The romantic relationship between [[Wataru Takagi]] and [[Miwako Sato]].
== Relationship analysis ==
[[Image:Takagi and Sato.jpg|thumb|250px|Takagi and Sato]]
'''[[Wataru Takagi]]''' and '''[[Miwako Sato]]''' are two officers working under Inspector Megure in the first division of the Tokyo Metropolitan Police Department, where Sato is currently Takagi's superior. As the story progresses, they start developing strong mutual romantic feelings for one another.

Despite being heavily admired by many male colleagues around her, especially Inspector [[Shiratori]] in the beginning, Sato still cares and worries about Takagi deeply, most notably during situations where his safety was put at risk. She also finds in Takagi traits that remind her of her late colleague, [[Jinpei Matsuda]], whom she had become romantically inclined towards in the brief time they've known each other. Takagi, on the other hand, respects Sato as his senior and loves her sincerely as a girlfriend, even to the point of willingly sacrificing his own life just to keep her away from all dangers.<ref>Manga: [[Volume 64]], File 673: "The Common Pattern"; Anime: [[The Scar that Evokes the Past]].</ref> After going through numerous difficulties and challenges, in some later cases, their relationship was hinted to have entered a sexual level; however, the true nature of this development has yet to be confirmed.<ref>'''Hints of sexual relationship:'''
* [[Volume 76]], File 806, Page 6 ([[The Life-Threatening Broadcast of Love]]): Sato accidentally reveals that she and Takagi have been sleeping together, and blushed awkwardly in response to the Detective Boys' speculation.
* [[Volume 82]], File 867, Page 6: Takagi accidentally reveals that he has slept on Sato's bed because he knows that it's "soft and fluffy", both of them blushed awkwardly in response to the Detective Boys' speculation; later in Page 9, Takagi whispers to Sato that "what was really soft and warm ''wasn't'', of course, the bedding..." in front of the kids, making her furiously embarrassed.
* [[Volume 82]], Files 869~871: Takagi misunderstands that Sato is pregnant, and is strongly convinced that the baby is his, which wouldn't make sense if they never had sexual relationship.</ref>

A running joke in the series is that their relationship never progresses because of interruptions by the rest of the police force or other characters.

=== ''Manga/Anime'' ===
==== [[Volume 12|Volume 21: Files 208-210]]/[[Metropolitan Police Detective Love Story|Episode 146-147: Metropolitan Police Detective Love Story]] ====
* Takagi tells the Detective Boys he has someone he likes and it's quickly inferred that it's Sato.
* Takagi is told that there is someone Sato likes in the 1st division and he wonders who it is, and worries if it is [[Ninzaburo Shiratori]].
* Shiratori invites Sato out for dinner at a french restaurant after the case is resolved, and is dejected when he gets rejected by Sato.
* Sato instead invites Takagi out, and then also invites Inspector Megure, making Takagi worried that the one Sato likes might be Megure instead of Shiratori.

==== [[Volume 23|Volume 23: File 231-233]]/[[Metropolitan Police Detective Love Story 2|Episode 156-157: Metropolitan Police Detective Love Story 2]] ====
* Takagi asks if Sato likes Inspector Megure (in that way), to which Sato replies yes (she misunderstood). She explains it's because he reminds her of her father, and Takagi realises what she means, that he misunderstood (from before). Sato teases and says he looks like he wants to say something more.

==== [[Volume 27|Volume 27: Files 267-269]]/[[Metropolitan Police Detective Love Story 3|Episode 205-206: Metropolitan Police Detective Love Story 3]] ====
[[Image:Takagi and Sato EP206 (1).jpg|thumb|250px]]
* Sato says she used to think she would grant the wish of the person who solves the mystery and catches Shuushirou, prompting Takagi and Shiratori to fantasise about Sato in a wedding dress. The Detective Boys immediately begin listing the wish they would like granted, and Sato thinks that only they would take it so seriously, but then notices the two men (Takagi and Shiratori) who have both gone quiet and looking like they're thinking hard (about their wishes), and she asks, "What's up with you two?"
* Takagi forgets his handcuffs and says the fortune telling magazine says he is super lucky today. It gives Sato flashbacks of the day her father died, when he left home he had forgotten his handcuffs and also said he had super lucky fortune that day. Sato gives old, rusty handcuffs to Takagi, telling him they are a memento of her father's and that it is sure to bring him luck. Shiratori looks decidedly put out.
* Later, Takagi is handcuffed into a building that has been set on fire, Sato wants to rush into the building but is stopped by Shiratori and Megure. As bits of the building crumbles, Sato yells out that Takagi is a baka, with tears in her eyes, only to hear Takagi answering her from behind them.
*Takagi had gotten out, but was still handcuffed to a metal bar, he collapses from the wound to his head, and Sato notices he has a gun and asks him why he didn't just shoot the handcuffs with his gun. The Detective Boys answer that it must have been because the handcuffs were the memento from Sato's father and he didn't want to damage them. Ai remarks that Takagi is the type to die early.
* Sato holds Takagi's unconscious body, and Shiratori stands to the side with his arms crossed.
* To show her thanks and to keep her promise (because Takagi figured out the mystery), she asks what he wants, and he says he wants to go somewhere sometime with her. He thinks it's a date, but Sato drags him along an undercover mission instead.

* A ticket to a magic show drops out of his jacket, and when asked, Takagi says that Yumi had an extra ticket and invited him, but that he said he wasn't interested. It was a plan Yumi thought up, to see whether Sato's face would change expression when she heard, but Sato instead encourages Takagi to go.
* Later, Takagi gets a phone call from Yumi asking how it went, he hangs up quickly shouting for her to call him at a better time, and Sato is behind him asking him what Yumi wanted.
* At the end of the episode, Yumi and Sato are talking, and Sato asks if Yumi likes Takagi. Yumi exclaims loudly, and thinks that her plan worked.
* Although Sato doesn't seem to care, the others remark that she is in an awfully good mood for someone who just got her pay cut (because a suspect had died in police custody) and "maybe something good happened."

* Yumi promises to send her "servant" (Takagi) to fake an emergency and save Sato, she texts Takagi but he is caught up with a case and doesn't read the mail until Conan using Shinichi's voice calls him and tells him the situation, that Shiratori and Sato have entered into a wager, if before sunset Takagi does not resolves the case and gets to them in time, Shiratori will take Sato as his wife, if Takagi does make it, then the whole thing will be forgotten.
* Sato agrees and thinks Takagi will definitely come, then she wonders why she thought he definitely would.
* Sato resigns herself to the deal, and thinks herself a failure as a police officer for not having noticed until now just how important Takagi has become to her.
* Just as Shiratori is about to seal their deal with a kiss, Conan uses Araide-sensei's shadow and his voice-changing bow tie to imitate Takagi's voice, stopping the kiss, and the deal.

'''{{nihongo|Naeko Miike|三池苗子|Miike Naeko}}''' is a character in the anime and manga franchise ''[[Detective Conan]]''. She is a childhood friend and the love interest of [[Kazunobu Chiba]].

== Background ==
Naeko Miike is a childhood friend of [[Kazunobu Chiba]] and [[Sakurako Yonehara]]. They all attended [[Teitan Elementary]] together where Kazonobu and Naeko both joined the school broadcasting commitee (although Naeko only joined because Chiba did). She then moved after her sixth grade summer. She works in the traffic department of the Tokyo Metropolitan Police District directly under [[Yumi Miyamoto]].

== Personality ==
Naeko is an extremely hardworking girl who bears great dedication to her work. However, she also possesses the notable trait of being very shy, which has ruined many of her chances to confess to Kazunobu Chiba about her true identity as his former classmate as well as her feelings for him. A running gag consists of Naeko always hiding her face and blushing heavily when she sees Kazunobu Chiba. She also has a friendly streak, in which she befriended her senior, Yumi Miyamoto, soon after she recently transferred to the latter's Division as well as Miwako Sato a short time after that. It is implied that she is quite observant, as shown when she noted and told Sato that Wataru Takagi was quite popular amongst women (though withholding the information from Sato herself that Takagi's popularity did not come close to matching the level of Sato's own impact around men).

== Abilites ==
It is revealed in [[The Mini Patrol Car Police's Big Chase|episode 918]] that Naeko is able to do karate. It is not confirmed by the manga. She was able to perform a throw, as she lifted a suspect with her hand and put him down knocking him out. She seems pretty experienced in martial arts.

== Plot overview ==
=== Video Letter of First Love (Manga: [[Volume 71|741-742]], Anime: [[A Video Letter of First Love|624]]) ===
When Naeko moved away, Chiba wrote down his feelings in a love letter. Naeko wrote her response on the side of a VHS in the committee storage room, hoping Chiba's sweating habit would cause the message "I like you, too" to show up on his hands after grabbing the tape. Unfortunately, Chiba couldn't find the right tape and never got the message.

On the day of his elementary school reunion, Chiba returned to the school and searched for the tape again. With the help of Conan and the Detective Boys he finally finds the message and heads for the reunion. Unfortunately Naeko doesn't show, and he hears from a former classmate that she said she is "now with the one she loved". Depressed, Chiba immediately leaves and finds a lady traffic cop giving him a ticket. When the officer offers to forget about the ticket since he is a fellow officer, Chiba scolds her for offering to ignore Chiba's illegal parking. Chiba leaves with the ticket, but then wonders how the girl knew he was a detective. The officer turns out to be Naeko, who has just been transferred to the police headquarters in Tokyo (working under Yumi) and looks forward to working with the one she loves.

=== The Joint Investigation with First Love (Manga: [[Volume 75|790-792]], Anime: [[Co-Investigating with a First Love|659-660]]) ===
Naeko makes her second appearence during a case involving threats that were placed in cars along with Yumi. Ironically, one of the victims happens to be Chiba himself. Naeko hides behind Yumi and continues to blush in front of him. However, Chiba remains oblivious to the fact that she is his childhood first love. She is forced into investigating the car cases with Chiba as Ayumi's, Mitsuhiko's and Genta's plan to get them to confess their love to each other. Soon after, a crash occurs and they find a man on the floor with another threat in the person's car. While everybody is investigating the current act of vandalism, Naeko helps out by giving information on the other cases. Meanwhile, Ayumi, Mitsuhiko and Genta continue to get Chiba to realize who Naeko really is, but he gets distracted by Conan, who keeps finding more evidence and Yumi who won't allow Chiba to steal her latest friend from her. Chiba comes close to finding out when a gust of wind blows Naeko's hat off, but is interrupted. Naeko feels like he doesn't remember her at all and calls him a dummy. Naeko continues to help with the investigation and they are able to find the culprit. Soon after Naeko takes Chiba home when Chiba remembers that he's seen her before. Naeko, thinking that he realizes she's his first love, is about to say that Chiba is correct when he says that it was from the time where she gave him a parking ticket. Naeko becomes embarrassed that she assumed wrong, but Chiba reveals to himself that he has a feeling who Naeko really is.

=== The Life-Threatening Broadcast of Love (Manga: [[Volume 76|804]], Anime: [[The Life-Threatening Broadcast of Love|681]]) ===
[[File:681-2.png|thumb|right]]
Naeko is first shown with Yumi in the Police Car where they meet Takagi, in which she guesses that he is going on a date with Sato to a hot spring for one night, and expresses surprise when Takagi denies so in a serious manner. Later at the police station, she teases Sato about the possibility of Takagi traveling to meet Sato's parents to ask for her hand, and introduces herself to Sato again when the latter forgets her name (much to her dismay). She voices out that she does not believe Takagi is committing a love affair when the trio discusses the reason behind his visit as he clearly stated that it was not a date and asks about Wataru Date when Yumi and Sato mentions the deceased police officer, to which she also considers the possibility Takagi visiting Date's parents. When the discussion hits the final result that Takagi can only be visiting a woman, Naeko remarks on Takagi's popularity with women, slightly sparking Sato's ire.

=== UFO Sighting Murder Case (Manga: [[Volume 89|942-944]], Anime: [[Chiba's Difficult UFO Case|847-848]]) ===
Naeko secretly send brochures about dieting plan to Chiba's house. Besides being busy with his investigation on the UFO sighting case, Chiba lost almost 10 kilograms after practicing the plan. Unexpectedly, this circumstance has made a few female police officers start being interested to attract Chiba. Naeko feels jealous and starts sending Chiba chocolates instead and this made Chiba's body return to his previous shape. The female police officers feel disappointed and say they do not interested in him anymore and that relieves Naeko.

=== Policewomen Serial Murder Case (Manga: [[Volume 95|1013-1017]], Anime: TBA) ===
Naeko makes a major appearence in this case since it involves the murder of policewomen, especially from the Traffic Divsion, with the presence of three suspects having violated traffic laws.

Later, Naeko is kidnapped by the culprit, after the latter took away her second phone while Naeko was trying to contact Chiba.
Chiba managed to rescue her and aprehend the culprit, but Naeko was injured in her right leg, while protecting Chiba from a bowgun arrow. While Naeko is being carried to the hospital in Chiba's back, the latter began to wonder if he should cross the red light since no one is around, however, Naeko managed to stop him from breaking the rules; using the same words that Chiba told her in the past.

Those words finally convinced Chiba that she was indeed his childhood friend Naeko, with the latter giving Chiba a hug. The couple goes to the hospital afterwards while blushing at the same time.

== Relationships analysis ==
=== [[Kazunobu Chiba]] ===
Chiba and Naeko were childhood friends and attended Teitan Elementary together were they both joined the school broadcasting committee (although Naeko only joined because Chiba did). When Naeko was to move away, Chiba wrote down his feelings in a love letter. Naeko wrote her response on the side of a VHS in the committee storage room, hoping Chiba's sweating habit would cause the message "I like you, too" to show up on his hands after grabbing the tape. Unfortunately, Chiba couldn't find the right tape and never got the message.

On the day of his elementary school reunion, Chiba returned to the school and searched for the tape again. With the help of Conan and the Detective Boys he finally finds the message and heads for the reunion. Unfortunately Naeko doesn't show, and he hears from a former classmate that she said she is "now with the one she loved". Depressed, Chiba immediately leaves and finds a lady traffic cop giving him a ticket. When the officer offers to forget about the ticket since he is a fellow officer, Chiba scolds her for offering to ignore Chiba's illegal parking. Chiba leaves with the ticket, but then wonders how the girl knew he was a police officer. The officer turns out to be Naeko, who has just been transferred to the police headquarters in Tokyo (working under Yumi) and looks forward to working with the one she loves. Despite this, Chiba is unable to identify Naeko as his childhood love, and Naeko has taken to hiding away in embarrassment upon seeing Chiba, though it is shown that Chiba has a slight feeling that he knows Naeko from before, even remembering that Naeko had spent a lot of time together with Sakurako when they were young.

=== [[Sakurako Yonehara]] ===
[[File:exboyfriend8765.jpg|right|thumb]]
Sakurako is Naeko's childhood friend and former neighbor. They are presumably close even back in their childhood days as Chiba, upon recognizing Sakurako, recalls that the latter always had Naeko by her side. Sakurako has also given Naeko the nickname "Nae-chan", and called her for help when she discovered a corpse at the house she was working at, showing that the two has kept in contact throughout the years.

=== [[Yumi Miyamoto]] ===
[[File:Yuminaekof04f3fdbb6fd5266b38c0b81aa18972bd5073607.jpg|right|thumb]]

'''{{nihongo|Yusaku Kudo|工藤優作|Kudō Yūsaku}}''' is the father of [[Shinichi Kudo]] and, along with his wife [[Yukiko Kudo|Yukiko]], is one of only a few characters to [[List of characters who know Conan's identity|know]] he is [[Conan Edogawa]]. He is also a world famous novelist and the creator of the popular [[Night Baron]] series.

== Background ==
[[File:Young Yusaku.jpg|thumb|left|Young Yusaku.]]
Yusaku Kudo was already noted for his sharp intellect and deductive abilities at a young age. He met Inspector Juzo Megure and became a good friend and valuable adviser to him in solving very difficult cases.<ref name="Call">Manga Chapter 204: The Initial Call</ref> While he often assisted the police, Yusaku's primary aspiration was that of a writer. Quickly attracting acclaim in his early twenties as a young novelist, he encountered the girl whom he resolved to marry: [[Yukiko Kudo|Yukiko Fujimine]], an already famed and beautiful actress. While taking her out in an expensive restaurant to make his proposal, he was involved in a murder case which he solved brilliantly, and right afterward proposed to a startled Yukiko - which she accepted (twenty years later, his son [[Shinichi Kudo|Shinichi]] would become involved in a follow-up of the exact same case in the exact same restaurant, but unlike Yusaku he wouldn't be able to profess his feelings to his own love, [[Ran Mouri]]).<ref>Manga Chapter 260: The Memorable Place</ref>

Yusaku's detective stories have won international acclaim, especially his novels involving the character called Night Baron, who has become a popular cultural item. He prefers to be known as a novelist, despite multiple demonstrations of a Mycroftian tendency to solve a case before Shinichi reaches the same conclusions (as in the OVA where Shinichi was trying to prove the alibi involving, supposedly, a black labrador dog). In the course of his career, he also encountered the first [[Toichi Kuroba|Kaitou Kid]] and struck a sort of competitive friendship with him; it is implied that Yusaku knew Kid's identity, but chose to chase Kid only during heists in order to foil the theft and no further.<ref name="Code">Manga Chapter 573: Setting Sun</ref>

After Shinichi becomes Conan, Yusaku learns from [[Hiroshi Agasa|Agasa]] what occurred, and stages an elaborate false kidnapping to drive home to Conan what the stakes are if he is caught by the [[Black Organization]]. He offers to take Conan to a new life in America, but understands when Shinichi refuses due to a desire for independence and feelings for Ran - though Yusaku doesn't expect that resolve to last.<ref name="Kidnapping">{{cite book |last=Aoyama |first=Gosho |title=Detective Conan |volume=6 |publisher=Shogakukan |date=1995-07-18 |isbn=4-09-123376-7 |chapter=File 1 |language=Japanese |location=Tokyo|}}</ref> He and Yukiko occasionally check up on Conan, but seem content to respect Shinichi's wishes to pursue the Black Organization without their help.

== Personality ==
Yusaku Kudo possesses a very sharp intellect and observation skills, traits which his son inherited, though Yusaku's own abilities remain more well-honed. He demonstrates in multiple cases an ability to operate one step ahead of both Shinichi and criminals, but he chooses to not get involved unless Conan appears unable solve the case alone in time to save the intended victim.<ref name="Train">Manga Chapter 218: The Last Station</ref><ref>Manga Chapter 752: A Troublesome and Difficult Case</ref><ref>Episode (English #99-102: The Cornered Detective)</ref> His success as a novelist is to a large part based on his keen understanding of the criminal mind, as his most famous recurring character is a criminal. While he is an excellent author, he will occasionally blow off his editors in order to do other things, such as travel with Yukiko.<ref name="Kidnapping"></ref> He is very laid back and calm, never seen to lose his temper. Some might think him too laid back, as he often took his son to crime scenes before Shinichi was eleven,<ref name="Call"></ref> and showed no concern over six-year-old Shinichi dragging Ran and Agasa into a potentially dangerous area of town to investigate a code.<ref>Manga Chapter 572: Broad Daylight</ref> The only time he has been shown to be caught off-guard or stressed by a situation is after the false kidnapping, when Shinichi alerts Yusaku's editors to his location and they force him to make up for missing his deadlines.<ref name="Kidnapping"></ref> His less tolerable personality traits include a certain cockiness and a very bad touch at making humor.<ref name="Train"></ref>

Yusaku loves to read, and is the one who compiled the massive library of mystery fiction Shinichi read as a child. His love of Sherlock Holmes is briefly explored in the non-[[canon]] 6th movie, '[[The Phantom of Baker Street]]', wherein Yusaku and Agasa helped develop one of the Cocoon VR modules as 19th Century London and included Holmes, Watson, and Irene Adler as non-playable characters modeled visually after Yusaku, Agasa, and Yukiko, respectively.

=== Yukiko Kudo ===
{{main|Yusaku Kudo and Yukiko Kudo}}
Not much is known about Yusaku and Yukiko's backstory before they get married. The most notable scene was from 20 years ago, when Yusaku and Yukiko met in a high end restaurant. Yusaku observed a murder crime, quickly solved it and suddenly proposed to a startled Yukiko, which she accepted. Despite occasional quarrels, they truly love each other and Yusaku fully supports Yukiko on her connections with the film industry after her retirement.

=== Shinichi Kudo/Conan Edogawa ===
Shinichi is his son and learns detective work from him. Yusaku began taking Shinichi to crime scenes as soon as Shinichi was 7 years old. Overall, Yusaku is a better detective, both from his experience and his astute observations that Shinichi sometimes misses. Yusaku fully supports Shinichi's goal and gives him the needed independence to solve cases, only dropping hints or stepping in when it is absolutely necessary. Although Yusaku and Yukiko left their son in Japan 3 years ago when they moved to America, they still supported him financially and occasionally came back to Japan to check their son's wellbeing.

When Shinichi shrunk into Conan, Yusaku staged a fake kidnapping scheme with Yukiko and Professor Agasa to make Shinichi realize the danger of the organization Shinichi was trying to investigate. He offered to bring Shinichi to America, which Shinichi refused. Since then, he still acted the same way towards Conan as before and limited his involvement with Black Organization, only helping his son on a single case by disguising as Subaru Okiya to fool Tooru Amuro.

Prototype antidote

2019-01-21T21:52:19Z

Bubbub907: /* Description */

[[File:Baijiu.jpg|thumb|The first known temporary antidote for APTX is [[baijiu]].]]
The {{nihongo|prototype antidote|解毒剤|gedoku-zai}} temporarily restores the body of someone de-aged by [[APTX 4869]] to their true age and appearance. The prototype antidote is created by [[Shiho Miyano]], the original creator of APTX 4869.

== Description ==
[[File:Transform animation.gif|thumb|right|The animation effect shown when the prototype antidote is either taking effect or wearing off.]]
Taking a prototype antidote causes [[Conan Edogawa]] and [[Ai Haibara]] to return to their original adult bodies for a short duration. The antidote lasts longer and has fewer side-effects than [[baijiu]]; the ones shown so far have typically lasted for about 24 hours or less. The transformation occurs as soon as the pill is taken, and there are no complications during the majority of the time that the antidote is in effect. However, when the antidote begins to wear off, Shinichi feels feverish, sweats profusely and experiences increasingly acute chest pain and heart palpitations. Shinichi reverts back into Conan soon after this.

Most of the times when Conan and Haibara have taken the prototype antidote, they were sick to some degree. It is unclear whether being ill is a requirement for the temporary antidote to act properly.

Unfortunately if a subsequent antidote dose is taken directly after the original dose, it works for far less time than the original dose. Taking the antidote frequently makes it less effective and shortens the active duration. Haibara cautions Shinichi that taking it consecutively will cause his body to develop resistance to it.<ref>Manga [[Volume 62]], File 11 (652), pg 9: "The Thing She Really Wants to Ask" </ref>

Ai Haibara developed the first prototype antidote after she discovered that consuming baijiu will temporarily restore a person shrunken by APTX 4869 to their original size.<ref>[[Reunion with the Black Organization]]</ref> While Haibara herself never directly states extracts of baijiu are part of the antidote, Conan implies that it is one component.<ref name=ep194>[[Episode 194]]</ref> It is also likely Haibara used APTX 4869 data she copied from the [[Black Organization]]'s files as part of the prototype antidote development process.<ref>Haibara made a copy of some of the APTX 4869 data when [[Reunion with the Black Organization|she was locked in a room with Pisco's computer]], but then lied to Conan about losing it. In [[The Desperate Revival|Episode 188]] (File 251), Haibara has the bloody disk of copied APTX 4869 data from [[Reunion with the Black Organization]] in a pile of other disks she has been using in her lab in Agasa's basement.</ref> Haibara characterizes these prototypes as quite dangerous. She cautions Shinichi that he could die when he tries it for the first time.

Haibara keeps a small stash of prototype antidote with her in a pill box in case a situation arises where she or Shinichi need to become adults. She withholds these extra from Conan, citing his tendency to misuse them or publicly appear as Shinichi.
{{clear}}

== Appearances ==
=== [[Canon]] ===
==== [[The Desperate Revival]] ====
A series of incidents led [[Ran]] to believe Conan is actually Shinichi who had been somehow shrunken. Before Conan could tell Ran the truth, Haibara reveals to Conan that she has developed a temporary antidote. After warning him that the temporary antidote was untested and could kill him, Conan agrees to take it as part of a trick to fool Ran by having both Conan and Shinichi appear at the same time. Shiho dresses up as Conan, and Shinichi secretly enters the school play as the mysterious Black Knight who would kiss the heroine played by Ran. Despite a murder interrupting the play, Ran saw both Conan and Shinichi at the same time, fooling her into no longer suspecting Shinichi and Conan were one and the same.<ref>[[Volume 26|Volume 26, Files 255-260]]</ref><ref>[[The Desperate Revival|Episodes 188-193: The Desperate Revival]]</ref>

The antidote ran out unexpectedly just before Shinichi was able to confess to Ran that he loved her.

==== [[Murderer, Shinichi Kudo]] ====
[[Image:Shinichi and Ran.jpg|thumb|After this scene, comes to where Shinichi almost confesses, this time his body here with Heiji's cap only lasting four hours.]]
Shinichi accidentally took the antidote prototype when [[Professor Agasa]] mistook it for cough medicine. This worked out to Shinichi's advantage because the culprit was in disguise as Shinichi, trying to implicate him for a crime. Shinichi was able to appear as himself and reveal the culprit's trick. The antidote wore off after 24 hours, forcing Haibara to give Shinichi another one to protect his identity. The second one wore off in a shortened 4 hours, again interrupting Shinichi's confession of his feelings to Ran.<ref>[[Volume 62|Volumes 62 & 63: Files 646-654]]</ref><ref>[[Murderer, Shinichi Kudo|Episode 521]]</ref><ref>[[Shinichi's True Face and Ran's Tears|Episode 522]]</ref><ref>[[What She Truly Wants to Ask|Episode 523]]</ref>

==== [[Holmes' Revelation]] ====
[[Image:Shinichi traveling.jpg|thumb|left|Shinichi on the plane after taking the pill.]]
Conan is given the antidote so he can fly to London, because the alias ''Conan Edogawa'' does not exist and has no passport.

Haibara passes to Conan a second pill for the trip back to Japan. However, after Conan accidentally reveals Shinichi is in London, Shinichi (as Conan) is chased by Ran, who doesn't know she is actually chasing Conan, but thinks it's Shinichi she chased. Conan hides in the booth and ingests the return-trip pill, and walks out of the booth. A bawling Ran runs away, and Shinichi runs after her. He grabs her arm and pulls her in front of him at the Big Ben, and this time nothing stopped him from confessing his feelings, somehow.

Fortunately for Shinichi, after he turns back to Conan and apprehends the terrorist together with [[Minerva Glass]], his parents [[Yusaku Kudo|Yusaku]] and [[Yukiko Kudo|Yukiko]] appear, giving him the third pill under orders from Haibara. He then goes back to Japan.<ref>[[Holmes' Revelation|Episode 616-621]]</ref><ref>[[Volume 71#Following Holmes|Volume 71, Files 743-751]]</ref><ref>[[Volume 72#Following Holmes|Volume 72, File 752]]</ref>

==== [[The Shadow Approaching Haibara's Secret]] ====
Shiho takes her first temporary antidote to break down the door of a burning shack to free herself and the Detective Boys. She hides in Agasa's camping tent until it wears off.

==== [[Crimson School Trip|Kyoto School Field Trip Case]] ====
To go to Kyoto for the school field trip, Conan took the antidotes provided by Haibara. Here Haibara provided Conan instructions when using multiple antidotes that he needed to wait 8 hours after being shrunk before taking the next one. Haibara added a footnote saying not to do anything too intimate while in the original body, although it's unclear whether it is related to the antidote.

=== Non-canon ===
==== [[The Stranger from Ten Years Later]] ====
The antidote Shinichi tried was a failure. Although he transformed, he was unconscious the whole time and had a vivid dream where he was still stuck as Conan a decade later. When he woke up, he transformed back to Conan.<ref>[[The Stranger from Ten Years Later|OVA, No. 9: The Stranger from Ten Years Later]]</ref>

== Speculation ==
While thinking about how to make a permanent antidote, [[Conan]] speculates that baijiu ingredients are not enough. Haibara adds that the APTX 4869 data is needed as well.<ref name=ep194/> Haibara in fact does have at least some APTX 4869 data. She copied some onto a floppy disk while [[Reunion with the Black Organization|she was locked in a room with Pisco's computer]], but then lied to Conan that she lost it.<ref>[[:File:Bloody Disk Manga.png|The bloody disk]] appears in [[The Desperate Revival]].</ref> Thus, there is some speculation that Haibara may have developed a full antidote, but is withholding it from Shinichi.

'''{{nihongo|Masumi Sera|世良真純|Sera Masumi}}''' is a high school detective in the manga and anime franchise ''[[Detective Conan]]''. She is the younger sister of [[Federal Bureau of Investigation|FBI]] agent [[Shuichi Akai]] and a practitioner of the martial art [[wikipedia:Jeet Kune Do|Jeet Kune Do]].

== Background ==
Masumi Sera is a high school detective and the younger sister of [[Federal Bureau of Investigation|FBI]] agent [[Shuichi Akai]] and shogi player, [[Shukichi Haneda]]. She is the only daughter of [[Tsutomu Akai]] and [[Mary]]. 17 years ago, her father, before he disappeared, instructed his family to hide in Japan, where Masumi later was born. Her oldest brother had prior to her birth left Japan to study in America, so they first got to meet each other when Masumi was six-seven years old. Although she grew up in Japan during her elementary school years, she moved abroad three years ago with her mother, presumably due to Shuichi infiltrating the [[Black Organization]]. Her other brother stayed in Japan. She has recently returned to Japan for some unknown reason. After meeting Conan, Ran, and Sonoko during a case, she transfers to [[Setting#Teitan High School (帝丹高校)|Ran's high school class]]. Masumi is skilled at [[Wikipedia:Jeet Kune Do|Jeet Kune Do]], a hobby encouraged by her brother Shuichi who mailed her instruction videos while in elementary school. She can fight on the same level as [[Ran Mouri|Ran]]. She seems to know that Conan is Shinichi and she had in fact met Ran and Shinichi sometime in their past. Currently she is living with [[Mary]], whom she calls "Mama", at a hotel. She claims that she is provided for by a rich friend of her late father, but it hasn't been revealed who it is. Every time they encounter the possibility of information on Mary getting out, they end up moving to a new hotel under Mary's order. While Masumi is eager to seek help from Conan, Mary is skeptical of him.
The three siblings has different last names. Sera is supposedly her mother's maiden name.

== Personality ==
[[File:691-15.png|thumb|Masumi beats a gangster in [[Yusaku Kudo's Cold Case]]]]
Masumi has a cheery, sociable, boyish personality<ref>Manga Volume 73, File 9, Page 3, "Let's hear your brilliant deduction!"</ref> and is well liked by her classmates at Teitan High. On their first meeting, Masumi fails to correct Sonoko's mistaken impression that she is a man and even makes it worse by declaring that Ran is "[her] type".<ref name=pronouns>The Japanese pronoun used is gender neutral and can refer to either males or females.</ref> Her rather boyish appearance - especially in relation with her flat chest - is a bit of a touchy subject to Masumi, who claims that her mother's bust size is rather well developed and keeps expressing her hope that someday her own chest size will similarly change for her.

Masumi is quite quick-minded, coming up with clever plans and adapting them to sudden changes rapidly. Masumi seems to be prone to dramatics like most detectives are, but perhaps to a lesser degree than [[Shinichi]] or [[Heiji]] as she bluntly says who the criminal is without preamble. On the other hand, Masumi is tough to the point that she is willing to risk all to achieve a successful conclusion of a case. In one instance, she purposefully lured a hostage-taker into a sniper's sight with a smile, hoping he would be shot without showing any apprehension about his possible demise.

Although she has crime scene experience<ref name=769p3>Manga Volume 73, File 7, pg 3: "A Detective Just Like You, Little Boy"</ref>, Masumi seems to be less skilled as a detective than Shinichi or Heiji, apparently missing a critical clue that was necessary to understand how the murderer's setup worked, although Conan opines that Masumi purposely made an error in order to test him. In some degree, she seems to like rivalry or contests to see who is the winner.

Sera's catchphrase upon the conclusion of a case is "case closed".

Sera shows a protective and caring side towards Conan, as seen in the Detectives Nocturne and in the beginning of the Red Woman case when she helps Conan up after falling, as well as having it made clear in the Haunted Hotel case that she was also clearly investigating Conan before they first met, as she knew he was a detective. It’s likely to believe that them being on the same bus was not an accident, which could even lead to be argued that she somehow hinted to them about the cake buffet so they would be on the same bus as her. It is safe to assume though she was, and possibly still is, investigating Conan.

Sera's way of referring to her parents as 'Mama' and 'Papa' indicates a privileges background.

== Appearance ==
[[File:Sera transfers.png‎|thumb|Masumi transfers to Teitan High School]]
At first, she wears a grey fedora that used to belong to Shuichi Akai and a dark jacket which gives her an androgynous appearance. When she transfers to Teitan High, she gets rid of her fedora and wears female clothing. Her hair is dark, wavy, and short; it doesn't even touch her shoulders. Even then, she is rather tomboyish; Genta mistakes her for a man, and Sonoko comments she has a petite figure. Later, Genta, Mitsuhiko and Hattori comment that her bosoms are rather small. Masumi also has an uneven tooth that shows when she smiles.

Masumi and her brother Shuichi presumably more closely resemble their mother than their father.

== Plot overview ==
=== Masumi's Introduction (Manga: [[Volume 73#Jeet Kune Do|768 - 770]], Anime: [[Deduction Showdown at the Haunted Hotel|646 - 647)]] ===
[[File:Sera_Kick.png|thumb|right|Masumi defends herself from Ran.]]
Masumi first met [[Sonoko Suzuki|Sonoko]], [[Ran Mouri|Ran]], and [[Conan Edogawa|Conan]] on a bus after she was mistaken for a [[Wikipedia:Groping|groper]]. After Sonoko declared Masumi was the groper, Masumi and Ran got into a fight, with Masumi's Jeet Kune Do holding even against Ran's karate. Conan and Masumi cleared up the misunderstanding by pointing out the real groper. Sonoko then mistook Masumi for a boy, an impression which wasn't helped by Masumi declaring that Ran was "his type".<ref name=pronouns/> Masumi and Ran both discovered they were heading to the same hotel, about which Conan is less than pleased.

Masumi finds out the hotel she is staying at doesn't have a room available and complains at the front desk. A man then falls into the parking lot and dies. Conan runs to the source of screaming while Masumi told the guard to watch the elevators before running to the roof. She immediately declares the crime to be a murder, giving her reasoning. She then reveals her name, Masumi, that she is a detective, and knows Conan is a detective as well. She also revealed before she knew Conan's name despite it not being mentioned in front of her, revealing that Masumi has been investigating Conan for awhile now.

[[Juzo Megure|Inspector Megure]] is not pleased to have another high school detective underfoot but lets Masumi and Conan investigate regardless. After listening to the suspect testimony, police observations, and examining the crime scene, Masumi announces that she has solved the case.

However, Masumi's deduction leaves out a critical detail; Conan is therefore forced to use Shinichi's phone to call his own, give Inspector Megure Conan's phone, and speak through Shinichi's as Shinichi using the voice-changer bow tie. Shinichi figures out the detail that had Masumi stumped, although a look she gives Conan as he runs off suggests her omission was possibly intentional, and once during the phone conversation she tries to trick Shinichi into admitting that he is physically present at the crime scene instead of being explained the details by Conan and Megure.

The following day, Masumi transfers to Teitan High School, surprising both Ran and Sonoko. She was rather popular at school surrounded by students asking her questions about herself.

=== Kogoro Detective Agency Hostage Crisis (Manga: [[Volume 73#Bomber's Request|771]]-[[Volume 74#Bomber's Request|774]], Anime: [[Hostage Situation at the Mouri Detective Agency|648 - 650]]) ===

==== Let's hear your brilliant deduction! (771) ====
According to Sonoko, Masumi has become very popular at Teitan high for being "cheery, sociable, boyish, and cute...and on top of that, she is a jeet kun do-using female detective!"<ref>Manga Volume 73, File 9, Page 3, "Let's hear your brilliant deduction!"</ref> One classmate compares her to [[Shinichi Kudo]] who has been taking a break from school. Masumi tells inquiring classmates that she has been staying in America with her parents since three years ago, but "rebelled" because she would rather live in her Japan where she was born and raised. She sneaks up behind Sonoko and Ran after school because she wanted to speak to Conan at the Mouri Detective Agency. At the agency, Masumi is unhappy to hear that Conan and the rest of Detective Boys are staying at Agasa's house and will be camping the following day. She settles for asking Kogoro if Conan is always at his side when he solves cases, hinting that she suspects Conan is the real brains behind "Sleeping Kogoro".

[[File:Sera slide_kick.png|thumb|left|Masumi sweeps out the Hostage Taker's legs]]
Just as Masumi is about to walk out the door, three female mystery writers and a man enter the agency. After a moment of confusion, the man suddenly fires a gun into the roof and takes the detective agency hostage. His demands are that Kogoro figure out which of the three writers killed his sister at a ryokan one month ago. The quick thinking Masumi sidles up to Ran and tells her to go for the man's gun after she takes his legs out. Sera's leg sweep sends the man to the floor, and Ran removes the gun from the man's hand with a kick; however, Masumi leaps back when the man reveals he has bombs strapped around his chest and will detonate them if they try to stop him.

Meanwhile at Agasa's, Haibara is angry that Conan used Shinichi's voice to solve a case around the suspicious Masumi. Conan's response is that Masumi is familiar somehow, like they have met before or she looks like someone, and Conan feels she isn't an enemy. Genta and Mitsuhiko told Conan they saw a high school student walking home with Ran, so the jealous Conan calls Ran's cellphone to hear about it from her.

The hostage taker man orders Ran to answer her phone, but Masumi snatches the phone away and says hello to Conan (who is shocked that Masumi is with Ran). Masumi then tricks the hostage taker and keeps the line connected so Conan can listen in by closing Ran's [[Yaiba#Characters|Sea Cucumber Man]] cellphone strap in between the screen and keypad of the the flip phone.

==== Nickname Rules (772) ====
Masumi asks a few insightful questions about the case; however the hostage taker man discovers Ran's phone is still connected. Under gunpoint, Masumi steps in front of Ran and takes the blame, but Conan, using Shinichi's voice, says he ordered Ran to do it. Masumi is mystified by why Shinichi is now on Conan's phone. Masumi meanwhile spots a glint of light across from the detective agency and declares that the case will come to an end without Shinichi's help.

==== Possible Sniping (773) ====
[[File:Sera773.png|thumb|right|Masumi surprised by Ran's attitude.]]
Masumi explains to Ran that she secretly kept the call to Conan connected so he could call the police and research into the case. While Masumi is still surprised that Shinichi was on the other end of the line instead of Conan, she had initially hoped that Shinichi would somehow be able to talk down the would-be-murderer. She suspects that Shinichi has already figured which one of the suspects is the murderer in the ryokan case, but Shinichi is unable to reveal the truth because the hostage taker would then kill the named culprit and then himself. Sera's plan changed when she noticed the lights from the police snipers on the building across from Mouri Detective Agency. She explains to Ran in detail the names and functions of the various police divisions responsible for hostage situations, and tells Ran in a roundabout fashion that this situation will end with the hostage taker being killed by the police.

Masumi launches a plan to bring the hostage taker into the snipers' range by telling him he should charge Ran's phone battery. Ran foils Sera's intentions by shutting the curtains, blocking the snipers' shot. To Masumi's utter astonishment, Ran tells her that she doesn't want to see anyone die in front of her and declares that "Shinichi won't allow anyone to die. He absolutely wouldn't!"<ref>Volume 73, File 11, page 13, "Possible Sniping." Shinichi then begins to present his deductions over the phone and Masumi wonders how he will manage to resolve this situation without bloodshed.</ref>

==== The book with unturned pages (774) ====
Masumi and Ran take the opportunity to disable the hostage taker when he loses his composure and grip on the detonator after Shinichi tricks him into believing his sister committed suicide. Masumi yells for the waiting bomb squad to secure the area. With the hostage taker arrested, Shinichi then reveals the true culprit. Masumi realizes the mistake in her deduction and explains the correct timeline of events before the murder. Sometime soon after the conclusion of the case, Masumi, walking with Ran and Sonoko speculates aloud that there must be some reason Shinichi left Agasa's before Ran could meet him there. She then exclaims that "due to what just happened, she really gets it", that Conan and Shinichi are on very good terms with one another, and that Ran "is tougher than Masumi thought". Conan isn't sure what to make of these last comments.

=== Video Site (Manga: [[Volume 74|775-777]], Anime: [[The Professor's Video Site|656-657]]) ===
[[File:Ai image.png|thumb|Masumi deletes Haibara's image]]
Masumi stops [[Genta Kojima|Genta]] and [[Mitsuhiko Tsuburaya|Mitsuhiko]] outside of [[Hiroshi Agasa|Agasa]]'s house to ask them if they are acquaintances of Professor Agasa. The topic of [[Shinichi]] comes up when she talks to Mitsuhiko and Genta about the prior hostage case. Mitsuhiko mentions that [[Ai Haibara|Haibara]] told them to keep Shinichi's involvement secret. After asking about Haibara, Masumi mentions that she saw Haibara in one of the professor's online videos. Next, Masumi asks who is currently living in the Kudo house because she saw the curtains shift slightly. The Detective Boys tell her that [[Subaru Okiya]] has been staying there since his apartment burnt down. Masumi cryptically comments with a smirk on her face, "And here I thought that someone had just settled in without permission...But it seems I was just getting worked up over nothing..." while looking up at where Subaru is hiding.

At the end of the case, Masumi is in her hotel room deleting various files. One of her deleted files was a still image from Agasa's video blown up to show Haibara reflected in Agasa's glasses. This indicates that she is not only keeping an eye on Conan but also on Haibara.
"Delete... Delete... For data, at least is an easy task to accomplish...", were her words while she was doing it.

Masumi proposes Heiji and Shinichi (via Conan's cellphone) have a deduction match. At the crime scene, Masumi becomes curious about the foreigner, Camel who secured the area. The police and Conan reveal Camel is an [[Federal Bureau of Investigation|FBI]] agent and Masumi takes interest. Meanwhile, Camel finds that Masumi looks familiar, but can't quite place why. He takes a picture of her and mails it to [[Jodie Starling|Jodie]] and [[James Black]] who are waiting outside. Jodie and James think Masumi resembles someone too, but only James Black correctly identified Masumi as female.

Meanwhile Masumi is busy helping with the case, asking questions and making comments about various deductions. Heiji nearly slips up with Conan's identity in front of her earning a pointed question from Masumi, but Heiji rescues himself by saying he thinks of Conan as Kudo when Conan gets smug have hearing Shinichi's deductions over the phone. Masumi doesn't seemed to be fooled though, her thoughts show that she seems to know Conan, not Shinichi, is the one solving the case while watching Conan come to his final conclusion.

Masumi isn't seen again for the rest of the case.

=== Murder at Mouri Detective Agency (Manga: [[Volume 76|797-800]], Anime: [[Detectives' Nocturne|672-674]]) ===
[[File:Sera's motorcycle.jpg|thumb|right|Masumi in her motorcycle.]]
During a murder case at Mouri Detective Agency, after meeting Kogoro's new apprentice [[Rei Furuya|Tooru Amuro]], [[Juzo Megure|Megure]] comments that the number of detectives around Kogoro has increased again, referring to Masumi. Amuro takes interest in Masumi. Later, Kogoro and friends go over to a suspect's apartment. Masumi calls Ran after hearing about the murder on the news because she is worried about her and Conan. The call has an usual amount of static which alerts Amuro that there are listening devices present. Amuro abruptly hangs up Ran's phone on Masumi. Meanwhile, Conan intentionally gets himself kidnapped by the primary suspect. After Ran enables calling again, Masumi calls back immediately and is very upset because she was worried something had happened to Ran. Ran tells her that Conan has been kidnapped, and details to Masumi the murder at Kogoro's agency. In order to figure out where the kidnapper is headed, Kogoro and Amuro search the apartment and decide to go to the address of one of the other suspects.

Masumi arrives at suspect's home on [[Cars|her motorcycle]], but just misses Kogoro and the gang leaving. She hears the elevator descending and rushes back downstairs in time to follow Amuro's [[Cars|car]]. Meanwhile, the culprit has been driving around with Conan while Haibara has been directing Okiya's car towards them using the criminal tracking glasses. Okiya catches up to the kidnapper and relays what the car looks like to Kogoro. Amuro sees the suspect's car heading in the opposite direction so he quickly wheels around after it. Masumi, who has been following Amuro's car this whole time, u-turns after Amuro and continues chasing. Amuro gets in front of the suspect's car and stops it. The suspect gets out of the car holding Conan at gunpoint, but Masumi drives up onto the roof of the car. She swings her motorcycle around so that the rear wheel slams into the woman's face knocking her unconscious. With tears of relief, Masumi hugs Conan, happy he is safe. Amuro, Okiya, and [[Vermouth]] look on.

Masumi is walking with Sonoko and Ran, and Ran is talking by phone with Conan. Masumi hears Haibara's voice in the background and becomes curious. She asks the two others what Haibara is like, and Sonoko says Haibara is like a woman in a child's body.

When Ran hangs up her cellphone, the topic switches over to [[Rei Furuya|Amuro]]. Masumi says to Ran she wants to meet Amuro because she never got a really good look at him from the last case, but Sonoko thinks she wants to meet Conan, instead. Ran says Shinichi and Conan are big fans of Sherlock Holmes. Masumi thinks about that she has known that for a long time.

Suddenly, Masumi sees [[Scar Akai]] in the crowd ahead. She runs after him, but she can't catch him. Ran wonders who Masumi was chasing, but Masumi replies she thought it was someone she knew, and silently appends in her mind that it would be impossible for the man she was chasing to be the person she thinks it was.

Both Subaru and Masumi had got more suspicious of Conan and the identity of Shinichi Kudo. At the end, when the criminals were knocked, she saw Ran and Conan and she thought she was a 'bad kid', after all.

=== Mystery Train (Manga: [[Volume 78|818-824]], Anime: [[The Jet-Black Mystery Train|701-704]]) ===
Masumi finally meets Haibara, and Haibara has a bad feeling about her (although it could have been due to Scar Akai spying on them from behind the door just then). Later when a murder occurs on the Bell Tree Express, she and Conan investigate. Masumi takes a video recording of the suspects running so she can show it to the detective boys in order to ask them which one had the closest gait to the masked suspect from earlier, but she is intercepted first by Scar Akai in the hallway. She stops and angrily asks him who he is. Scar Akai simply replies that she hasn't changed, reveals his face to her, and refers to her by her first name, "Masumi". In her shock Masumi calls him "Shu-nii", signifying that Shuichi is Masumi's older brother. She questions Scar Akai about what happened, saying that she heard he had died. Scar Akai then tasers her unconscious, stating that he was hoping for that response. Scar Akai later is revealed to be Vermouth in disguise, explaining why he attacked Masumi.

=== The Blush Mermaid Heist (Manga: [[Volume 78|828]]-[[Volume 79|830]], Anime: [[Kaitou Kid and the Blush Mermaid|724-725]]) ===

Masumi accompanies Conan, Ran, and Sonoko to the location of Kaitou Kid's next heist: a museum where the Blush Mermaid, a gem adhered to the shell of a turtle as a last ditch effort by a an Italian actress in an accident at sea to save her turtle by encouraging someone to rescue it. Before checking out the museum, Masumi asks Ran if she saw a [[Scar Akai|strange man in black]] when she found the hat on the Belltree Express. After the group arrives at the room where the turtle is being held in a large aquarium, [[Ginzo Nakamori|Inspector Nakamori]] pulls Masumi's face to see if it is a mask worn by Kid. Annoyed by Nakamori's mistaken gender assumption and having her face pinched, Masumi knees him in the privates ostensibly to prove he isn't Kid. Masumi then runs off to the bathroom. Later, when Kid makes his move, Masumi is one of many caught in his trap: the rug on the floor is pulled up by strings so that it pins everyone standing on it to the front of aquarium. As soon as the rug drops, everyone sees the tank is empty except for a card left by Kid. This leaves Conan and Masumi quite dumbfounded as to how Kaitou Kid could have removed the turtle. Later, Conan reveals that Masumi is really Kaitou Kid, and he had made a critical error in his acting by assuming Masumi was a male. Kaitou Kid had locked the real Masumi bound and gagged in the men's bathroom after knocking her out with a stun gun. Upon gaining consciousness, Masumi escapes her bonds, rushes out of the bathroom, and gives a still disguised Kid a fierce kick to the face. After Kid escapes (due to Ran distracting Masumi by pointing out that everyone can see her underwear), Masumi is relieved that she at least managed to recover her hat, which she thinks is special because it somehow has the same feel as her brother Shuichi Akai's hat.

Furthermore, Masumi explains to Conan that her brother also advises her on cases by phone. After successfully investigating the crime scene with Conan, Masumi steps aside with her smartphone and types in the message "It seems like he's also arrived at the truth... But whether or not our deductions are the same - lately I've been losing confidence in that regard...". When the recipient writes back "Who is he? I'd like an explanation!", Masumi takes a picture with her smartphone. However, the recipient's answer, "If it's him, there's no problem." reveals that he is familiar with Conan. It is heavily implied that it is the same person Conan saw Masumi making a call with in File 857.

Masumi asks the child is she is beginning to like him, but the child responds that she is still long way from trusting him. The child asks Masumi to tell Conan she is her little sister from outside the territory if he asks about her. Masumi doesn't mention that she showed Conan the child's picture.

Sera appeared in this movie as an investigator of the person who had been shot in the Bell Tower. She and Conan helped in chasing the culprit and afterwards was shot by the culprit after saving Conan.

== Plot Exposition ==
=== Hints that Masumi was Shuichi Akai's sister ===
Masumi was revealed to be Shuichi Akai's sister on the Bell Tree Express after a confrontation with [[Scar Akai]]<ref name=821p16>Manga [[Volume 78]], File 4 (821), pg 16: "Mystery Train (Junction)"</ref> and while sleeptalking.<ref name=823p4>Manga [[Volume 78]], File 6 (823), pg 4: "Mystery Train (Releasing Smoke)"</ref>
[[File:Sera_and_Shuuichi.png|thumb|right|Masumi and [[Shuichi Akai]].]]
* Masumi has bags under her eyes identical to Shuichi Akai's.
* Masumi Sera's name is also incredibly similar to Mobile Suit Gundam character [http://gundam.wikia.com/wiki/Sayla_Mass Sayla Mass] ({{lang|ja|セイラ・マス}}, ''Seira Masu''). [[Shuichi Akai#Name origin|Shuichi's name is derived]] from Sayla Mass's older brother's name, Char Aznable.
* Conan said he has a feeling he had met her before. "''Somehow I feel like we've met somewhere before, it might be that person resembles someone I know, that's why the feeling that we've met before is on my mind...''"<ref>Manga Chapter 771: Let's Hear Your Brilliant Deduction! p.11</ref>
* [[Andre Camel]] and most likely [[James Black]] seem to recognize her from somewhere. On another interesting note, James was the first to recognize that Masumi was a girl. Everyone else thought that she was a guy when they first saw her. Since James was Shuichi's boss, he would most likely know that Shuichi has a younger sister and what she would look like.
* Masumi lived in Japan until three years ago when her family moved to America. This matches with the time when Shuichi was infiltrating the Black Organization. The family's move to America could be the FBI's attempt to protect them should something go wrong with Shuichi's mission.
* In Chapter 801, Masumi chased after [[Scar Akai]] who appeared while she was walking with Ran in front of the Mouri Detective Agency. Although, Scar Akai hid before she could find him, she told Ran that she had just seen "someone she knew".
* In Chapter 859, Masumi, when being asked who taught her Jeet Kune Do, answers that her older brother did. Consequently, Conan asks Sera: "But, didn't you say your older brother was dead?" This leads to Masumi remarking "Yeah... That's what I heard." also further supporting the theory that Masumi is in Japan to investigate her brother's death.

=== Hints that Masumi was not Bourbon ===
* In Chapter 801, Masumi chased after [[Scar Akai]] who appeared while she was walking with Ran in front of the Mouri Detective Agency. Although, Scar Akai hid before she could find him, she told Ran that she had just seen "someone she knew". She then thinks there is "no way it was possible" regarding the man she saw, which would make sense if she thought Shuichi was dead. This implied she wasn't Bourbon, since Bourbon believes he is the only one who can kill Shuichi, implying that Gin might have failed to do so. Hence Bourbon wouldn't think that it was impossible to meet Shuichi again in the street.

== Relationships analysis ==
=== Friends and family ===
==== Shuichi Akai ====
[[Shuichi Akai]] is Masumi's older brother. She didn't get to meet him until she was six-seven years old, because Shuichi went to study abroad before Masumi was born. At first meeting she was very shy, but she did make some pranks in an attempt to make him smile. Masumi refers to Shuichi as "Shu-nii", implying that they were close. Masumi seems to miss him after his supposed death. In the Blush Mermaid Heist, Masumi is shown to be fond of her fedora as she believes it has the same "feel" as Shuichi's old hats. Shuichi sent Masumi Jeet-Kune-Do training tapes while she was in elementary school. She watched these so many times while practicing that she wore them out.<ref name="876p2">Manga [[Volume 83]], File 4 (876), pg 2: "Romance Novelist"</ref> She describes her eldest brother as ''strong'' in contrast to her second - oldest brother.<ref name="859p6-7">Manga [[Volume 81]], File 9 (859): pgs 6-7: "Jeet Kune Do vs. Karate"</ref>

==== Conan Edogawa ====
[[File:EP671-674 25.png|thumb|right|Masumi hugs Conan after rescuing him in [[Detectives' Nocturne]].]]
Masumi is interested in [[Conan Edogawa|Conan]]'s abilities as a detective and has been gathering information on him and his friends. She appears to be certain that Conan is Shinichi Kudo. Despite her initial suspicious presentation, Conan felt like she wasn't a bad person and so didn't mistrust her. Conan at several points questions her if they've met before, but she denies this, once secretly thinking, "Now's not the time". The period in which such an encounter could have taken place is initially hinted to be somewhere before the three-year span of Masumi's sojourn in the United States, when she was in her preteen years.<ref name="Mang83">Manga [[Volume 83]], File 2 (874), pg 7-8: "Red Past"</ref><ref name="Mang86">Manga [[Volume 86]], File 1 (905): "The Truth Rises to the Surface"</ref>

It is later shown that she had met Conan/Shinichi ten years ago, when the Akai family had gathered on an undisclosed beach in Japan prior to Shuichi Akai joining the FBI. By chance, Shinichi and [[Ran Mouri|Ran]] had also vacationed there, and they all ended up as witnesses and investigators in a gone-awry flight attempt from a robbery. When Shinichi managed to make Shuichi laugh (something Masumi had miserably failed to achieve) with his intelligence, observation skills and some unintended jokes, Masumi, in her admiration for Shinichi, began to call him "wizard". It is quite possible that this meeting inspired Masumi to become a detective herself.<ref name="Mang92">Manga [[Volume 92]], File 2-4 (972-974): "A Chance Meeting at the Beach"</ref>

If Masumi really lived in England, instead of America, then it's possible that she saw the tennis match from the London case on TV and recognized Conan as Shinichi based on his proclamation as 'Holmes' apprentice'.

On several occasions, such as the dramatic conclusion of the [[Volume 76#Online Client|Online Client Case]], Masumi has displayed an intensely affectionate air towards Conan which somewhat transcends a mere "big sister" relationship.<ref>Manga Chapter 800: ''Online Client Case'' - "When Objects Collide"; Anime Episode 674: ''[[Detectives' Nocturne]]'' - "Bourbon"</ref> In fact, it is hinted during the [[Volume 83#Romance Novelist Murder Case|Romance Novelist murder]] and in the movie ''[[Dimensional Sniper]]'' that she may actually be entertaining a crush on Shinichi/Conan and hopes of initiating a closer relationship with him. However, the actual level of her feelings for him is yet to be publicly revealed. However it doesn't seem like she has anything against Ran and Shinichi's relationship.

==== Ai Haibara ====
Masumi has been interested in meeting [[Ai Haibara]] for yet unrevealed reasons and has been secretly gathering information on her. She also seemed to recognize [[Shiho Miyano]] in the video of her rescuing the [[Detective Boys]]. Haibara in turn feels uneasy around Masumi, especially in close contact situations though arguably it could also be due to Scar Akai's presence near Masumi. The reason behind her interest might be due to Haibara's resemblance with [[Mary]].

==== Ran Mouri ====
[[File:Ran and Sera and Wave.jpg|thumb|left|Ran hears sounds of rippling waves when she sees Masumi hurried away]]
Since enrolling at Teitan High, Masumi and [[Ran Mouri|Ran]] have become friends and often walk home from school together. Masumi has also declared Ran as "her type" when they first met as a sign of liking, though this ultimately led Sonoko, Conan and Ran herself to mistake Masumi for a boy.

At one point, Ran recalls having met Masumi before in the past, hearing the sound of "rippling waves" when the she sees the latter leaving, "as if some sort of magic were at work".<ref name="Mang86"></ref> It is revealed in a later story that she and Masumi had actually met 10 years before, when they were both still children, on a beach, where by happenstance she, Shinichi and the Akai family inadvertently became embroiled in the aftermath of a crime (see '''Conan Edogawa''', above).<ref name="Mang92"></ref>

==== Sonoko Suzuki ====
Since enrolling at Teitan High, Masumi and [[Sonoko Suzuki|Sonoko]] have become friends and often walk home from school together, with Sonoko describing Masumi as a popular girl who is "cheery, sociable, boyish and cute" and on top of that, a "Jeet Kune Do using detective", though she also teasingly remarks that the only thing "against Sera" is her flat chest.

==== Shukichi Haneda/Akai family's middle brother ====
Masumi appears to have a good relationship with her [[Akai family's middle brother|second-older brother]] and often consults him regarding information or deductions about the cases she faced, and also has a high regard of her brother's intellect, even considering the already sharp Shuichi as "strong" in contrast to her second older-brother.

==== Tsutomu Akai ====
Masumi's father was missing before she was born, so she never knew him. But she refer to him as 'Papa.

==== Mary Sera ====
[[Mary Sera|Mary]] seems very mature and cold while talking to Masumi. She also treats her more like a coworker than her daughter, as she always advises her what to do and switch hotels if any intel about Mary is leaked.She is also somehow stubborn as she declined Masumi's trust in Conan despite the latter's motive and pursuit of justice are geniune.

=== Black Organization ===
==== Rei Furuya ====
Rei first saw Masumi in Detectives Nocturne case and seemed to recognise her. They formally met in chapter 936 (Girls Band) at [[Café Poirot]]. Masumi felt like having met him and even asked him directly about that, but Rei said that was the first time they met. When Masumi talked about a friend of her brother who taught her play the guitar, Rei also seemed to know about that incident. In Masumi's flashback of that friend, a man who looked very much like Rei appeared, and Masumi once again wondered about it, to which Amuro replied that she took the wrong person.

==== Scotch ====
Sera recalled meeting Scotch 4 years ago. That was when Scotch was with Akai and Rei in a train station. Sera also remembered Scotch teaching her how to play the bass and though it was only 10 minutes, she seemed to enjoy it. Sera is not sure of Scotch's true identity or allegiance, but thinks that Scotch is Japanese and that Scotch is not the real name.

== Speculation ==
[[File:Sera Knowing Conan's Name.png‎|thumb|right|Masumi mentioning Conan's name.]]
=== Masumi met Shinichi and Ran when she was younger and knows Conan is Shinichi ===
* Masumi knew [[Conan Edogawa|Conan]] and [[Ran Mouri|Ran]]'s identities before they introduced themselves. She also knew that Conan is a detective.<ref> [[Volume 73]], File 6 (768)</ref>
* Masumi seems to know that Conan is the brains behind Sleeping Kogoro. Conan seems to think that he may have met Masumi before or that she resembles someone that he knows. He believes that she got the deduction of a case wrong just so that he would reveal himself. <ref> [[Volume 73]], File 9 (771)</ref>
* Conan realizes he met Masumi before because he finds her snaggletoothed smile familiar,<ref name=845p16>Manga [[Volume 80]], File 6 (845), pg 16: "Our Territory"</ref>
* Masumi admits that she has met Conan before, but she can´t tell him until "the time" comes.<ref name=846p16>Manga [[Volume 80]], File 7 (846), pg 16: "The Magic Lock"</ref>
* Ran has met Masumi as well because Masumi's figure as she runs away reminds her of "sounds of rippling waves, as if some sort of magic were at work."<ref name=846p4>Manga [[Volume 80]], File 7 (846), pg 4: "The Magic Lock"</ref>
* Masumi, asks Conan if he once met a girl "a long time ago and could never forget [her]"<ref name=876p11>Manga [[Volume 83]], File 4 (876), pg 11: "The Romance Novelist"</ref> and gets annoyed when he says he can't recall someone like that.
* Ran has a flashback to when she saw a younger Masumi, who is wearing a bathing suit, say, "You are a wizard, right?". Ran also feels that she has met [[Mary]].<ref> Manga [[Volume 86]], File 1 (905)</ref>
* The meeting occurred 10 years ago, as mentioned by Mary.<ref> Manga [[Volume 90]], File 5 (953)</ref>
* Masumi puts on a swimsuit similar to the one in Ran's flashback in order to jog Conan's memory, which results in him remembering her in that bathing suit as well, along as three other people, assumed to be her relatives. <ref> Manga [[Volume 91]], File 11 (969)</ref>

In Chapter 771, it is revealed that she also knows Professor Agasa, although she calls him "Professor what's his name". Although this could be explained away as her talking to Conan off screen and her just not remembering Agasa's name.

=== Identity of Masumi's middle brother ===
{{main|Akai family's middle brother}}

=== The Wizard ===
In a PS, [[Akai family's middle brother|Masumi's middle brother]] asks if she "has already met the Wizard?"<ref name=861p15-16>Manga Volume 81, File 11 (861), pg 15-16: "Just like Magic"</ref> Masumi's thought reply is "You could say so..." Later, Masumi "thinks aloud" that her reason for returning to Japan is to meet the Wizard once more.<ref name=874p8>Manga [[Volume 83]], File 2 (874), pg 8: "The red past"</ref> The identity of the Wizard is revealed in File 974 to be Shinichi.

==== Shinichi Kudo ====
Tellingly, Masumi turns towards Conan when thinking of the answer "You could say so". At this point Masumi seems to know Conan is Shinichi. If Shinichi was nicknamed "The Wizard" by Masumi and/or her brother because of what happened when he and Masumi met in the past, then the response is appropriate since she could only sort of meet with Shinichi, because Shinichi shrunk into Conan. It's possible that the event where Shinichi earned the nickname "The Wizard" was Shinichi and Ran's meeting with Masumi 10 years ago. When trying to remember Masumi, Ran specifically mentions "sounds of rippling waves, as if some sort of magic were at work."<ref name=846p4>Manga [[Volume 80]], File 7 (846), pg 4: "The Magic Lock"</ref> A "magical" incident, if it was Shinichi's doing, might have earned him the nickname. Ran has a flashback of a young Masumi saying "You are a wizard, right?".<ref> Manga [[Volume 86]], File 1 (905)</ref> Conan seems to have remembered meeting Masumi 10 years ago and is shown as a young Shinichi standing in front of a large wave.<ref> Manga [[Volume 92]], File 2 (971)</ref>

==== Someone else ====
At this point it is unlikely that the Wizard is anyone else. There is evidence that Masumi nicknamed the person who she calls Wizard, at a point in the past while Ran was nearby. If Ran was nearby, then this would have to have happened when they first met 10 years ago, meaning that the person must be someone who existed back then. The topic of the Wizard came up during a text conversation about Conan between Masumi and her middle brother, and her response to if she had met the Wizard again was "You could say so", which is more than likely implying that she is referring to Conan, and therefore Shinichi.

[[File:Akai's picture 338.PNG|thumb|right|The picture of the Detective Boys the mystery assistants captured]]

=== Masumi learned about Haibara from Shuichi's picture ===
Masumi initially had an interest in Haibara. This is strange because Haibara didn't exist prior to Shiho shrinking. The knowledge of Shiho should have been secret to her as well, because Shuichi Akai's infiltration of the Black Organization was a secret. If Masumi doesn't even know the details of her brother's death, why should she know about Shiho? Masumi may recognize Haibara from pictures of Conan and Haibara that Shuichi took back during the Vermouth arc. It is standard procedure in the US to send the personal belongings of the dead back to their families. If Shuichi mixed these pictures in with his own things when he took them out of his truck before meeting with Kir, it's possible they were overlooked when the FBI sent Shuichi 's things to his family. If Masumi was interested in finding out how and why Shuichi died, she would begin by researching the people in those pictures and those connected with them in hopes of finding clues.

== Name origin ==
{{nihongo|Masumi Sera's|世良・真純|Sera Masumi}} name comes from the [[Wikipedia: Mobile Suit Gundam|Mobile Suit Gundam]] character {{nihongo|[[Wikipedia: Sayla Mass|Sayla Mass]]|セイラ・マス|Seira Masu}}.<ref>[[Sherry's soliloquy|Sherry's soliloquy (2012-06-17)]], Gosho was referring to the revelation that Masumi is Shuichi's sister (Manga File 821): {{lang|ja|やっぱりアルテイシアだったのね・・・}} (So it was '''Artesia'''…). Note that "Artesia" is another name of '''Sayla Mass'''.</ref> The kanji for Masumi's surname mean 'good world'. The kanji for her first name, Masumi, mean 'true' and either 'pure' or 'net.'

== Trivia ==
[[File:M18-Sera.jpg|thumb|right|Movie 18]]
* Masumi is based on [[Natsuki Koshimizu]], a tomboy detective girl turned criminal who made her first appearance in the [[Volume 54#Detective Koshien Case|''Detective Koshien Case'']]. Since Natsuki had proven highly popular, but Aoyama couldn't recycle her as a protagonist, the character of Masumi was created instead.<ref>''Shonen Sunday'' #33</ref>
* When she was young she liked to read the "[[Night Baron]]" series, so she is fan of [[Yusaku Kudo]].
* Her catchphrase, "Case Closed" (said in English), is likely a reference to the English-language name of Detective Conan. It was later revealed that she first heard the phrase being used by her brother Shuichi after he solved a case, most likely inspiring Masumi to use it herself as well.
* Masumi owns an [[Vehicles in Detective Conan#Sera's Yamaha Artesia XT400|Artesia XT400]].
* In File 859, Masumi reveals that she has a second-older brother and that her oldest brother taught her Jeet-Kune-Do.
* Masumi speaks Queen's English.<ref>[[:File:Postcard2015 1.jpg]]</ref>
* In movie 18, Sera's breasts are mistakenly a little bit developed.

'''{{nihongo|Masumi Sera|世良真純|Sera Masumi}}''' is a high school detective in the manga and anime franchise ''[[Detective Conan]]''. She is the younger sister of [[Federal Bureau of Investigation|FBI]] agent [[Shuichi Akai]] and a practitioner of the martial art [[wikipedia:Jeet Kune Do|Jeet Kune Do]].

== Background ==
Masumi Sera is a high school detective and the younger sister of [[Federal Bureau of Investigation|FBI]] agent [[Shuichi Akai]] and shogi player, [[Shukichi Haneda]]. She is the only daughter of [[Tsutomu Akai]] and [[Mary]]. 17 years ago, her father, before he disappeared, instructed his family to hide in Japan, where Masumi later was born. Her oldest brother had prior to her birth left Japan to study in America, so they first got to meet each other when Masumi was six-seven years old. Although she grew up in Japan during her elementary school years, she moved abroad three years ago with her mother, presumably due to Shuichi infiltrating the [[Black Organization]]. Her other brother stayed in Japan. She has recently returned to Japan for some unknown reason. After meeting Conan, Ran, and Sonoko during a case, she transfers to [[Setting#Teitan High School (帝丹高校)|Ran's high school class]]. Masumi is skilled at [[Wikipedia:Jeet Kune Do|Jeet Kune Do]], a hobby encouraged by her brother Shuichi who mailed her instruction videos while in elementary school. She can fight on the same level as [[Ran Mouri|Ran]]. She seems to know that Conan is Shinichi and she had in fact met Ran and Shinichi sometime in their past. Currently she is living with [[Mary]], whom she calls "Mama", at a hotel. She claims that she is provided for by a rich friend of her late father, but it hasn't been revealed who it is. Every time they encounter the possibility of information on Mary getting out, they end up moving to a new hotel under Mary's order. While Masumi is eager to seek help from Conan, Mary is skeptical of him.
The three siblings has different last names. Sera is supposedly her mother's maiden name.

== Personality ==
[[File:691-15.png|thumb|Masumi beats a gangster in [[Yusaku Kudo's Cold Case]]]]
Masumi has a cheery, sociable, boyish personality<ref>Manga Volume 73, File 9, Page 3, "Let's hear your brilliant deduction!"</ref> and is well liked by her classmates at Teitan High. On their first meeting, Masumi fails to correct Sonoko's mistaken impression that she is a man and even makes it worse by declaring that Ran is "[her] type".<ref name=pronouns>The Japanese pronoun used is gender neutral and can refer to either males or females.</ref> Her rather boyish appearance - especially in relation with her flat chest - is a bit of a touchy subject to Masumi, who claims that her mother's bust size is rather well developed and keeps expressing her hope that someday her own chest size will similarly change for her.

Masumi is quite quick-minded, coming up with clever plans and adapting them to sudden changes rapidly. Masumi seems to be prone to dramatics like most detectives are, but perhaps to a lesser degree than [[Shinichi]] or [[Heiji]] as she bluntly says who the criminal is without preamble. On the other hand, Masumi is tough to the point that she is willing to risk all to achieve a successful conclusion of a case. In one instance, she purposefully lured a hostage-taker into a sniper's sight with a smile, hoping he would be shot without showing any apprehension about his possible demise.

Although she has crime scene experience<ref name=769p3>Manga Volume 73, File 7, pg 3: "A Detective Just Like You, Little Boy"</ref>, Masumi seems to be less skilled as a detective than Shinichi or Heiji, apparently missing a critical clue that was necessary to understand how the murderer's setup worked, although Conan opines that Masumi purposely made an error in order to test him. In some degree, she seems to like rivalry or contests to see who is the winner.

Sera's catchphrase upon the conclusion of a case is "case closed".

Sera shows a protective and caring side towards Conan, as seen in the Detectives Nocturne and in the beginning of the Red Woman case when she helps Conan up after falling, as well as having it made clear in the Haunted Hotel case that she was also clearly investigating Conan before they first met, as she knew he was a detective. It’s likely to believe that them being on the same bus was not an accident, which could even lead to be argued that she somehow hinted to them about the cake buffet so they would be on the same bus as her. It is safe to assume though she was, and possibly still is, investigating Conan.

Sera's way of referring to her parents as 'Mama' and 'Papa' indicates a privileges background.

== Appearance ==
[[File:Sera transfers.png‎|thumb|Masumi transfers to Teitan High School]]
At first, she wears a grey fedora that used to belong to Shuichi Akai and a dark jacket which gives her an androgynous appearance. When she transfers to Teitan High, she gets rid of her fedora and wears female clothing. Her hair is dark, wavy, and short; it doesn't even touch her shoulders. Even then, she is rather tomboyish; Genta mistakes her for a man, and Sonoko comments she has a petite figure. Later, Genta, Mitsuhiko and Hattori comment that her bosoms are rather small. Masumi also has an uneven tooth that shows when she smiles.

Masumi and her brother Shuichi presumably more closely resemble their mother than their father.

== Plot overview ==
=== Masumi's Introduction (Manga: [[Volume 73#Jeet Kune Do|768 - 770]], Anime: [[Deduction Showdown at the Haunted Hotel|646 - 647)]] ===
[[File:Sera_Kick.png|thumb|right|Masumi defends herself from Ran.]]
Masumi first met [[Sonoko Suzuki|Sonoko]], [[Ran Mouri|Ran]], and [[Conan Edogawa|Conan]] on a bus after she was mistaken for a [[Wikipedia:Groping|groper]]. After Sonoko declared Masumi was the groper, Masumi and Ran got into a fight, with Masumi's Jeet Kune Do holding even against Ran's karate. Conan and Masumi cleared up the misunderstanding by pointing out the real groper. Sonoko then mistook Masumi for a boy, an impression which wasn't helped by Masumi declaring that Ran was "his type".<ref name=pronouns/> Masumi and Ran both discovered they were heading to the same hotel, about which Conan is less than pleased.

Masumi finds out the hotel she is staying at doesn't have a room available and complains at the front desk. A man then falls into the parking lot and dies. Conan runs to the source of screaming while Masumi told the guard to watch the elevators before running to the roof. She immediately declares the crime to be a murder, giving her reasoning. She then reveals her name, Masumi, that she is a detective, and knows Conan is a detective as well. She also revealed before she knew Conan's name despite it not being mentioned in front of her, revealing that Masumi has been investigating Conan for awhile now.

[[Juzo Megure|Inspector Megure]] is not pleased to have another high school detective underfoot but lets Masumi and Conan investigate regardless. After listening to the suspect testimony, police observations, and examining the crime scene, Masumi announces that she has solved the case.

However, Masumi's deduction leaves out a critical detail; Conan is therefore forced to use Shinichi's phone to call his own, give Inspector Megure Conan's phone, and speak through Shinichi's as Shinichi using the voice-changer bow tie. Shinichi figures out the detail that had Masumi stumped, although a look she gives Conan as he runs off suggests her omission was possibly intentional, and once during the phone conversation she tries to trick Shinichi into admitting that he is physically present at the crime scene instead of being explained the details by Conan and Megure.

The following day, Masumi transfers to Teitan High School, surprising both Ran and Sonoko. She was rather popular at school surrounded by students asking her questions about herself.

=== Kogoro Detective Agency Hostage Crisis (Manga: [[Volume 73#Bomber's Request|771]]-[[Volume 74#Bomber's Request|774]], Anime: [[Hostage Situation at the Mouri Detective Agency|648 - 650]]) ===

==== Let's hear your brilliant deduction! (771) ====
According to Sonoko, Masumi has become very popular at Teitan high for being "cheery, sociable, boyish, and cute...and on top of that, she is a jeet kun do-using female detective!"<ref>Manga Volume 73, File 9, Page 3, "Let's hear your brilliant deduction!"</ref> One classmate compares her to [[Shinichi Kudo]] who has been taking a break from school. Masumi tells inquiring classmates that she has been staying in America with her parents since three years ago, but "rebelled" because she would rather live in her Japan where she was born and raised. She sneaks up behind Sonoko and Ran after school because she wanted to speak to Conan at the Mouri Detective Agency. At the agency, Masumi is unhappy to hear that Conan and the rest of Detective Boys are staying at Agasa's house and will be camping the following day. She settles for asking Kogoro if Conan is always at his side when he solves cases, hinting that she suspects Conan is the real brains behind "Sleeping Kogoro".

[[File:Sera slide_kick.png|thumb|left|Masumi sweeps out the Hostage Taker's legs]]
Just as Masumi is about to walk out the door, three female mystery writers and a man enter the agency. After a moment of confusion, the man suddenly fires a gun into the roof and takes the detective agency hostage. His demands are that Kogoro figure out which of the three writers killed his sister at a ryokan one month ago. The quick thinking Masumi sidles up to Ran and tells her to go for the man's gun after she takes his legs out. Sera's leg sweep sends the man to the floor, and Ran removes the gun from the man's hand with a kick; however, Masumi leaps back when the man reveals he has bombs strapped around his chest and will detonate them if they try to stop him.

Meanwhile at Agasa's, Haibara is angry that Conan used Shinichi's voice to solve a case around the suspicious Masumi. Conan's response is that Masumi is familiar somehow, like they have met before or she looks like someone, and Conan feels she isn't an enemy. Genta and Mitsuhiko told Conan they saw a high school student walking home with Ran, so the jealous Conan calls Ran's cellphone to hear about it from her.

The hostage taker man orders Ran to answer her phone, but Masumi snatches the phone away and says hello to Conan (who is shocked that Masumi is with Ran). Masumi then tricks the hostage taker and keeps the line connected so Conan can listen in by closing Ran's [[Yaiba#Characters|Sea Cucumber Man]] cellphone strap in between the screen and keypad of the the flip phone.

==== Nickname Rules (772) ====
Masumi asks a few insightful questions about the case; however the hostage taker man discovers Ran's phone is still connected. Under gunpoint, Masumi steps in front of Ran and takes the blame, but Conan, using Shinichi's voice, says he ordered Ran to do it. Masumi is mystified by why Shinichi is now on Conan's phone. Masumi meanwhile spots a glint of light across from the detective agency and declares that the case will come to an end without Shinichi's help.

==== Possible Sniping (773) ====
[[File:Sera773.png|thumb|right|Masumi surprised by Ran's attitude.]]
Masumi explains to Ran that she secretly kept the call to Conan connected so he could call the police and research into the case. While Masumi is still surprised that Shinichi was on the other end of the line instead of Conan, she had initially hoped that Shinichi would somehow be able to talk down the would-be-murderer. She suspects that Shinichi has already figured which one of the suspects is the murderer in the ryokan case, but Shinichi is unable to reveal the truth because the hostage taker would then kill the named culprit and then himself. Sera's plan changed when she noticed the lights from the police snipers on the building across from Mouri Detective Agency. She explains to Ran in detail the names and functions of the various police divisions responsible for hostage situations, and tells Ran in a roundabout fashion that this situation will end with the hostage taker being killed by the police.

Masumi launches a plan to bring the hostage taker into the snipers' range by telling him he should charge Ran's phone battery. Ran foils Sera's intentions by shutting the curtains, blocking the snipers' shot. To Masumi's utter astonishment, Ran tells her that she doesn't want to see anyone die in front of her and declares that "Shinichi won't allow anyone to die. He absolutely wouldn't!"<ref>Volume 73, File 11, page 13, "Possible Sniping." Shinichi then begins to present his deductions over the phone and Masumi wonders how he will manage to resolve this situation without bloodshed.</ref>

==== The book with unturned pages (774) ====
Masumi and Ran take the opportunity to disable the hostage taker when he loses his composure and grip on the detonator after Shinichi tricks him into believing his sister committed suicide. Masumi yells for the waiting bomb squad to secure the area. With the hostage taker arrested, Shinichi then reveals the true culprit. Masumi realizes the mistake in her deduction and explains the correct timeline of events before the murder. Sometime soon after the conclusion of the case, Masumi, walking with Ran and Sonoko speculates aloud that there must be some reason Shinichi left Agasa's before Ran could meet him there. She then exclaims that "due to what just happened, she really gets it", that Conan and Shinichi are on very good terms with one another, and that Ran "is tougher than Masumi thought". Conan isn't sure what to make of these last comments.

=== Video Site (Manga: [[Volume 74|775-777]], Anime: [[The Professor's Video Site|656-657]]) ===
[[File:Ai image.png|thumb|Masumi deletes Haibara's image]]
Masumi stops [[Genta Kojima|Genta]] and [[Mitsuhiko Tsuburaya|Mitsuhiko]] outside of [[Hiroshi Agasa|Agasa]]'s house to ask them if they are acquaintances of Professor Agasa. The topic of [[Shinichi]] comes up when she talks to Mitsuhiko and Genta about the prior hostage case. Mitsuhiko mentions that [[Ai Haibara|Haibara]] told them to keep Shinichi's involvement secret. After asking about Haibara, Masumi mentions that she saw Haibara in one of the professor's online videos. Next, Masumi asks who is currently living in the Kudo house because she saw the curtains shift slightly. The Detective Boys tell her that [[Subaru Okiya]] has been staying there since his apartment burnt down. Masumi cryptically comments with a smirk on her face, "And here I thought that someone had just settled in without permission...But it seems I was just getting worked up over nothing..." while looking up at where Subaru is hiding.

At the end of the case, Masumi is in her hotel room deleting various files. One of her deleted files was a still image from Agasa's video blown up to show Haibara reflected in Agasa's glasses. This indicates that she is not only keeping an eye on Conan but also on Haibara.
"Delete... Delete... For data, at least is an easy task to accomplish...", were her words while she was doing it.

The case opens with Ran talking to Masumi about [[Heiji Hattori]] who is stopping by for a visit. Masumi is curious whether Heiji or Shinichi is the better detective. After Heiji is introduced to Masumi, Kazuha then calls Heiji and tells him that she is stuck at a restaurant because someone died and a foreigner [[Andre Camel]] is keeping everyone from leaving. Masumi proposes Heiji and Shinichi (via Conan's cellphone) have a deduction match. At the crime scene, Masumi becomes curious about the foreigner, Camel who secured the area. The police and Conan reveal Camel is an [[Federal Bureau of Investigation|FBI]] agent and Masumi takes interest. Meanwhile, Camel finds that Masumi looks familiar, but can't quite place why. He takes a picture of her and mails it to [[Jodie Starling|Jodie]] and [[James Black]] who are waiting outside. Jodie and James think Masumi resembles someone too, but only James Black correctly identified Masumi as female.

Meanwhile Masumi is busy helping with the case, asking questions and making comments about various deductions. Heiji nearly slips up with Conan's identity in front of her earning a pointed question from Masumi, but Heiji rescues himself by saying he thinks of Conan as Kudo when Conan gets smug have hearing Shinichi's deductions over the phone. Masumi doesn't seemed to be fooled though, her thoughts show that she seems to know Conan, not Shinichi, is the one solving the case while watching Conan come to his final conclusion.

During a murder case at Mouri Detective Agency, after meeting Kogoro's new apprentice [[Rei Furuya|Tooru Amuro]], [[Juzo Megure|Megure]] comments that the number of detectives around Kogoro has increased again, referring to Masumi. Amuro takes interest in Masumi. Later, Kogoro and friends go over to a suspect's apartment. Masumi calls Ran after hearing about the murder on the news because she is worried about her and Conan. The call has an usual amount of static which alerts Amuro that there are listening devices present. Amuro abruptly hangs up Ran's phone on Masumi. Meanwhile, Conan intentionally gets himself kidnapped by the primary suspect. After Ran enables calling again, Masumi calls back immediately and is very upset because she was worried something had happened to Ran. Ran tells her that Conan has been kidnapped, and details to Masumi the murder at Kogoro's agency. In order to figure out where the kidnapper is headed, Kogoro and Amuro search the apartment and decide to go to the address of one of the other suspects.

Masumi arrives at suspect's home on [[Cars|her motorcycle]], but just misses Kogoro and the gang leaving. She hears the elevator descending and rushes back downstairs in time to follow Amuro's [[Cars|car]]. Meanwhile, the culprit has been driving around with Conan while Haibara has been directing Okiya's car towards them using the criminal tracking glasses. Okiya catches up to the kidnapper and relays what the car looks like to Kogoro. Amuro sees the suspect's car heading in the opposite direction so he quickly wheels around after it. Masumi, who has been following Amuro's car this whole time, u-turns after Amuro and continues chasing. Amuro gets in front of the suspect's car and stops it. The suspect gets out of the car holding Conan at gunpoint, but Masumi drives up onto the roof of the car. She swings her motorcycle around so that the rear wheel slams into the woman's face knocking her unconscious. With tears of relief, Masumi hugs Conan, happy he is safe. Amuro, Okiya, and [[Vermouth]] look on.

Masumi is walking with Sonoko and Ran, and Ran is talking by phone with Conan. Masumi hears Haibara's voice in the background and becomes curious. She asks the two others what Haibara is like, and Sonoko says Haibara is like a woman in a child's body.

When Ran hangs up her cellphone, the topic switches over to [[Rei Furuya|Amuro]]. Masumi says to Ran she wants to meet Amuro because she never got a really good look at him from the last case, but Sonoko thinks she wants to meet Conan, instead. Ran says Shinichi and Conan are big fans of Sherlock Holmes. Masumi thinks about that she has known that for a long time.

Suddenly, Masumi sees [[Scar Akai]] in the crowd ahead. She runs after him, but she can't catch him. Ran wonders who Masumi was chasing, but Masumi replies she thought it was someone she knew, and silently appends in her mind that it would be impossible for the man she was chasing to be the person she thinks it was.

=== Mystery Train (Manga: [[Volume 78|818-824]], Anime: [[The Jet-Black Mystery Train|701-704]]) ===

She stops and angrily asks him who he is. Scar Akai simply replies that she hasn't changed, reveals his face to her, and refers to her by her first name, "Masumi". In her shock Masumi calls him "Shu-nii", signifying that Shuichi is Masumi's older brother. She questions Scar Akai about what happened, saying that she heard he had died. Scar Akai then tasers her unconscious, stating that he was hoping for that response. Scar Akai later is revealed to be Vermouth in disguise, explaining why he attacked Masumi.

Masumi accompanies Conan, Ran, and Sonoko to the location of Kaitou Kid's next heist: a museum where the Blush Mermaid, a gem adhered to the shell of a turtle as a last ditch effort by a an Italian actress in an accident at sea to save her turtle by encouraging someone to rescue it. Before checking out the museum, Masumi asks Ran if she saw a [[Scar Akai|strange man in black]] when she found the hat on the Belltree Express. After the group arrives at the room where the turtle is being held in a large aquarium, [[Ginzo Nakamori|Inspector Nakamori]] pulls Masumi's face to see if it is a mask worn by Kid. Annoyed by Nakamori's mistaken gender assumption and having her face pinched, Masumi knees him in the privates ostensibly to prove he isn't Kid. Masumi then runs off to the bathroom. Later, when Kid makes his move, Masumi is one of many caught in his trap: the rug on the floor is pulled up by strings so that it pins everyone standing on it to the front of aquarium. As soon as the rug drops, everyone sees the tank is empty except for a card left by Kid. This leaves Conan and Masumi quite dumbfounded as to how Kaitou Kid could have removed the turtle. Later, Conan reveals that Masumi is really Kaitou Kid, and he had made a critical error in his acting by assuming Masumi was a male. Kaitou Kid had locked the real Masumi bound and gagged in the men's bathroom after knocking her out with a stun gun. Upon gaining consciousness, Masumi escapes her bonds, rushes out of the bathroom, and gives a still disguised Kid a fierce kick to the face. After Kid escapes (due to Ran distracting Masumi by pointing out that everyone can see her underwear), Masumi is relieved that she at least managed to recover her hat, which she thinks is special because it somehow has the same feel as her brother Shuichi Akai's hat.

I'd like an explanation!", Masumi takes a picture with her smartphone. However, the recipient's answer, "If it's him, there's no problem." reveals that he is familiar with Conan.

Sera appeared in this movie as an investigator of the person who had been shot in the Bell Tower. She and Conan helped in chasing the culprit and afterwards was shot by the culprit after saving Conan.

== Plot Exposition ==
=== Hints that Masumi was Shuichi Akai's sister ===
Masumi was revealed to be Shuichi Akai's sister on the Bell Tree Express after a confrontation with [[Scar Akai]]<ref name=821p16>Manga [[Volume 78]], File 4 (821), pg 16: "Mystery Train (Junction)"</ref> and while sleeptalking.<ref name=823p4>Manga [[Volume 78]], File 6 (823), pg 4: "Mystery Train (Releasing Smoke)"</ref>
[[File:Sera_and_Shuuichi.png|thumb|right|Masumi and [[Shuichi Akai]].]]
* Masumi has bags under her eyes identical to Shuichi Akai's.
* Masumi Sera's name is also incredibly similar to Mobile Suit Gundam character [http://gundam.wikia.com/wiki/Sayla_Mass Sayla Mass] ({{lang|ja|セイラ・マス}}, ''Seira Masu''). [[Shuichi Akai#Name origin|Shuichi's name is derived]] from Sayla Mass's older brother's name, Char Aznable.
* Conan said he has a feeling he had met her before. "''Somehow I feel like we've met somewhere before, it might be that person resembles someone I know, that's why the feeling that we've met before is on my mind...''"<ref>Manga Chapter 771: Let's Hear Your Brilliant Deduction! p.11</ref>
* [[Andre Camel]] and most likely [[James Black]] seem to recognize her from somewhere. On another interesting note, James was the first to recognize that Masumi was a girl. Everyone else thought that she was a guy when they first saw her. Since James was Shuichi's boss, he would most likely know that Shuichi has a younger sister and what she would look like.
* Masumi lived in Japan until three years ago when her family moved to America. This matches with the time when Shuichi was infiltrating the Black Organization. The family's move to America could be the FBI's attempt to protect them should something go wrong with Shuichi's mission.
* In Chapter 801, Masumi chased after [[Scar Akai]] who appeared while she was walking with Ran in front of the Mouri Detective Agency. Although, Scar Akai hid before she could find him, she told Ran that she had just seen "someone she knew".
* In Chapter 859, Masumi, when being asked who taught her Jeet Kune Do, answers that her older brother did. Consequently, Conan asks Sera: "But, didn't you say your older brother was dead?" This leads to Masumi remarking "Yeah... That's what I heard." also further supporting the theory that Masumi is in Japan to investigate her brother's death.

=== Hints that Masumi was not Bourbon ===
* In Chapter 801, Masumi chased after [[Scar Akai]] who appeared while she was walking with Ran in front of the Mouri Detective Agency. Although, Scar Akai hid before she could find him, she told Ran that she had just seen "someone she knew". She then thinks there is "no way it was possible" regarding the man she saw, which would make sense if she thought Shuichi was dead. This implied she wasn't Bourbon, since Bourbon believes he is the only one who can kill Shuichi, implying that Gin might have failed to do so. Hence Bourbon wouldn't think that it was impossible to meet Shuichi again in the street.

[[Shuichi Akai]] is Masumi's older brother. She didn't get to meet him until she was six-seven years old, because Shuichi went to study abroad before Masumi was born. At first meeting she was very shy, but she did make some pranks in an attempt to make him smile. Masumi refers to Shuichi as "Shu-nii", implying that they were close. Masumi seems to miss him after his supposed death. In the Blush Mermaid Heist, Masumi is shown to be fond of her fedora as she believes it has the same "feel" as Shuichi's old hats. Shuichi sent Masumi Jeet-Kune-Do training tapes while she was in elementary school. She watched these so many times while practicing that she wore them out.<ref name="876p2">Manga [[Volume 83]], File 4 (876), pg 2: "Romance Novelist"</ref> She describes her eldest brother as ''strong'' in contrast to her second - oldest brother.<ref name="859p6-7">Manga [[Volume 81]], File 9 (859): pgs 6-7: "Jeet Kune Do vs. Karate"</ref>

==== Conan Edogawa ====
[[File:EP671-674 25.png|thumb|right|Masumi hugs Conan after rescuing him in [[Detectives' Nocturne]].]]
Masumi is interested in [[Conan Edogawa|Conan]]'s abilities as a detective and has been gathering information on him and his friends. She appears to be certain that Conan is Shinichi Kudo. Despite her initial suspicious presentation, Conan felt like she wasn't a bad person and so didn't mistrust her. Conan at several points questions her if they've met before, but she denies this, once secretly thinking, "Now's not the time". The period in which such an encounter could have taken place is initially hinted to be somewhere before the three-year span of Masumi's sojourn in the United States, when she was in her preteen years.<ref name="Mang83">Manga [[Volume 83]], File 2 (874), pg 7-8: "Red Past"</ref><ref name="Mang86">Manga [[Volume 86]], File 1 (905): "The Truth Rises to the Surface"</ref>

It is later shown that she had met Conan/Shinichi ten years ago, when the Akai family had gathered on an undisclosed beach in Japan prior to Shuichi Akai joining the FBI. By chance, Shinichi and [[Ran Mouri|Ran]] had also vacationed there, and they all ended up as witnesses and investigators in a gone-awry flight attempt from a robbery. When Shinichi managed to make Shuichi laugh (something Masumi had miserably failed to achieve) with his intelligence, observation skills and some unintended jokes, Masumi, in her admiration for Shinichi, began to call him "wizard". It is quite possible that this meeting inspired Masumi to become a detective herself.<ref name="Mang92">Manga [[Volume 92]], File 2-4 (972-974): "A Chance Meeting at the Beach"</ref>

If Masumi really lived in England, instead of America, then it's possible that she saw the tennis match from the London case on TV and recognized Conan as Shinichi based on his proclamation as 'Holmes' apprentice'.

On several occasions, such as the dramatic conclusion of the [[Volume 76#Online Client|Online Client Case]], Masumi has displayed an intensely affectionate air towards Conan which somewhat transcends a mere "big sister" relationship.<ref>Manga Chapter 800: ''Online Client Case'' - "When Objects Collide"; Anime Episode 674: ''[[Detectives' Nocturne]]'' - "Bourbon"</ref> In fact, it is hinted during the [[Volume 83#Romance Novelist Murder Case|Romance Novelist murder]] and in the movie ''[[Dimensional Sniper]]'' that she may actually be entertaining a crush on Shinichi/Conan and hopes of initiating a closer relationship with him. However, the actual level of her feelings for him is yet to be publicly revealed. However it doesn't seem like she has anything against Ran and Shinichi's relationship.

==== Ai Haibara ====
Masumi has been interested in meeting [[Ai Haibara]] for yet unrevealed reasons and has been secretly gathering information on her. She also seemed to recognize [[Shiho Miyano]] in the video of her rescuing the [[Detective Boys]]. Haibara in turn feels uneasy around Masumi, especially in close contact situations though arguably it could also be due to Scar Akai's presence near Masumi. The reason behind her interest might be due to Haibara's resemblance with [[Mary]].

==== Ran Mouri ====
[[File:Ran and Sera and Wave.jpg|thumb|left|Ran hears sounds of rippling waves when she sees Masumi hurried away]]
Since enrolling at Teitan High, Masumi and [[Ran Mouri|Ran]] have become friends and often walk home from school together. Masumi has also declared Ran as "her type" when they first met as a sign of liking, though this ultimately led Sonoko, Conan and Ran herself to mistake Masumi for a boy.

At one point, Ran recalls having met Masumi before in the past, hearing the sound of "rippling waves" when the she sees the latter leaving, "as if some sort of magic were at work".<ref name="Mang86"></ref> It is revealed in a later story that she and Masumi had actually met 10 years before, when they were both still children, on a beach, where by happenstance she, Shinichi and the Akai family inadvertently became embroiled in the aftermath of a crime (see '''Conan Edogawa''', above).<ref name="Mang92"></ref>

==== Sonoko Suzuki ====
Since enrolling at Teitan High, Masumi and [[Sonoko Suzuki|Sonoko]] have become friends and often walk home from school together, with Sonoko describing Masumi as a popular girl who is "cheery, sociable, boyish and cute" and on top of that, a "Jeet Kune Do using detective", though she also teasingly remarks that the only thing "against Sera" is her flat chest.

==== Shukichi Haneda/Akai family's middle brother ====
Masumi appears to have a good relationship with her [[Akai family's middle brother|second-older brother]] and often consults him regarding information or deductions about the cases she faced, and also has a high regard of her brother's intellect, even considering the already sharp Shuichi as "strong" in contrast to her second older-brother.

==== Tsutomu Akai ====
Masumi's father was missing before she was born, so she never knew him. But she refer to him as 'Papa.

==== Mary Sera ====
[[Mary Sera|Mary]] seems very mature and cold while talking to Masumi. She also treats her more like a coworker than her daughter, as she always advises her what to do and switch hotels if any intel about Mary is leaked.She is also somehow stubborn as she declined Masumi's trust in Conan despite the latter's motive and pursuit of justice are geniune.

=== Black Organization ===
==== Rei Furuya ====
Rei first saw Masumi in Detectives Nocturne case and seemed to recognise her. They formally met in chapter 936 (Girls Band) at [[Café Poirot]]. Masumi felt like having met him and even asked him directly about that, but Rei said that was the first time they met. When Masumi talked about a friend of her brother who taught her play the guitar, Rei also seemed to know about that incident. In Masumi's flashback of that friend, a man who looked very much like Rei appeared, and Masumi once again wondered about it, to which Amuro replied that she took the wrong person.

==== Scotch ====
Sera recalled meeting Scotch 4 years ago. That was when Scotch was with Akai and Rei in a train station. Sera also remembered Scotch teaching her how to play the bass and though it was only 10 minutes, she seemed to enjoy it. Sera is not sure of Scotch's true identity or allegiance, but thinks that Scotch is Japanese and that Scotch is not the real name.

== Speculation ==
[[File:Sera Knowing Conan's Name.png‎|thumb|right|Masumi mentioning Conan's name.]]
=== Masumi met Shinichi and Ran when she was younger and knows Conan is Shinichi ===
* Masumi knew [[Conan Edogawa|Conan]] and [[Ran Mouri|Ran]]'s identities before they introduced themselves. She also knew that Conan is a detective.<ref> [[Volume 73]], File 6 (768)</ref>
* Masumi seems to know that Conan is the brains behind Sleeping Kogoro. Conan seems to think that he may have met Masumi before or that she resembles someone that he knows. He believes that she got the deduction of a case wrong just so that he would reveal himself. <ref> [[Volume 73]], File 9 (771)</ref>
* Conan realizes he met Masumi before because he finds her snaggletoothed smile familiar,<ref name=845p16>Manga [[Volume 80]], File 6 (845), pg 16: "Our Territory"</ref>
* Masumi admits that she has met Conan before, but she can´t tell him until "the time" comes.<ref name=846p16>Manga [[Volume 80]], File 7 (846), pg 16: "The Magic Lock"</ref>
* Ran has met Masumi as well because Masumi's figure as she runs away reminds her of "sounds of rippling waves, as if some sort of magic were at work."<ref name=846p4>Manga [[Volume 80]], File 7 (846), pg 4: "The Magic Lock"</ref>
* Masumi, asks Conan if he once met a girl "a long time ago and could never forget [her]"<ref name=876p11>Manga [[Volume 83]], File 4 (876), pg 11: "The Romance Novelist"</ref> and gets annoyed when he says he can't recall someone like that.
* Ran has a flashback to when she saw a younger Masumi, who is wearing a bathing suit, say, "You are a wizard, right?". Ran also feels that she has met [[Mary]].<ref> Manga [[Volume 86]], File 1 (905)</ref>
* The meeting occurred 10 years ago, as mentioned by Mary.<ref> Manga [[Volume 90]], File 5 (953)</ref>
* Masumi puts on a swimsuit similar to the one in Ran's flashback in order to jog Conan's memory, which results in him remembering her in that bathing suit as well, along as three other people, assumed to be her relatives. <ref> Manga [[Volume 91]], File 11 (969)</ref>

In Chapter 771, it is revealed that she also knows Professor Agasa, although she calls him "Professor what's his name". Although this could be explained away as her talking to Conan off screen and her just not remembering Agasa's name.

=== Identity of Masumi's middle brother ===
{{main|Akai family's middle brother}}

=== The Wizard ===
In a PS, [[Akai family's middle brother|Masumi's middle brother]] asks if she "has already met the Wizard?"<ref name=861p15-16>Manga Volume 81, File 11 (861), pg 15-16: "Just like Magic"</ref> Masumi's thought reply is "You could say so..." Later, Masumi "thinks aloud" that her reason for returning to Japan is to meet the Wizard once more.<ref name=874p8>Manga [[Volume 83]], File 2 (874), pg 8: "The red past"</ref> The identity of the Wizard is revealed in File 974 to be Shinichi.

==== Shinichi Kudo ====
Tellingly, Masumi turns towards Conan when thinking of the answer "You could say so". At this point Masumi seems to know Conan is Shinichi. If Shinichi was nicknamed "The Wizard" by Masumi and/or her brother because of what happened when he and Masumi met in the past, then the response is appropriate since she could only sort of meet with Shinichi, because Shinichi shrunk into Conan. It's possible that the event where Shinichi earned the nickname "The Wizard" was Shinichi and Ran's meeting with Masumi 10 years ago. When trying to remember Masumi, Ran specifically mentions "sounds of rippling waves, as if some sort of magic were at work."<ref name=846p4>Manga [[Volume 80]], File 7 (846), pg 4: "The Magic Lock"</ref> A "magical" incident, if it was Shinichi's doing, might have earned him the nickname. Ran has a flashback of a young Masumi saying "You are a wizard, right?".<ref> Manga [[Volume 86]], File 1 (905)</ref> Conan seems to have remembered meeting Masumi 10 years ago and is shown as a young Shinichi standing in front of a large wave.<ref> Manga [[Volume 92]], File 2 (971)</ref>

==== Someone else ====
At this point it is unlikely that the Wizard is anyone else. There is evidence that Masumi nicknamed the person who she calls Wizard, at a point in the past while Ran was nearby. If Ran was nearby, then this would have to have happened when they first met 10 years ago, meaning that the person must be someone who existed back then. The topic of the Wizard came up during a text conversation about Conan between Masumi and her middle brother, and her response to if she had met the Wizard again was "You could say so", which is more than likely implying that she is referring to Conan, and therefore Shinichi.

[[File:Akai's picture 338.PNG|thumb|right|The picture of the Detective Boys the mystery assistants captured]]

=== Masumi learned about Haibara from Shuichi's picture ===
Masumi initially had an interest in Haibara. This is strange because Haibara didn't exist prior to Shiho shrinking. The knowledge of Shiho should have been secret to her as well, because Shuichi Akai's infiltration of the Black Organization was a secret. If Masumi doesn't even know the details of her brother's death, why should she know about Shiho? Masumi may recognize Haibara from pictures of Conan and Haibara that Shuichi took back during the Vermouth arc. It is standard procedure in the US to send the personal belongings of the dead back to their families. If Shuichi mixed these pictures in with his own things when he took them out of his truck before meeting with Kir, it's possible they were overlooked when the FBI sent Shuichi 's things to his family. If Masumi was interested in finding out how and why Shuichi died, she would begin by researching the people in those pictures and those connected with them in hopes of finding clues.

* Masumi ranked 11th in the Digest Book 80+ poll "Character you want to marry", with 281 votes.

== Name origin ==
{{nihongo|Masumi Sera's|世良・真純|Sera Masumi}} name comes from the [[Wikipedia: Mobile Suit Gundam|Mobile Suit Gundam]] character {{nihongo|[[Wikipedia: Sayla Mass|Sayla Mass]]|セイラ・マス|Seira Masu}}.<ref>[[Sherry's soliloquy|Sherry's soliloquy (2012-06-17)]], Gosho was referring to the revelation that Masumi is Shuichi's sister (Manga File 821): {{lang|ja|やっぱりアルテイシアだったのね・・・}} (So it was '''Artesia'''…). Note that "Artesia" is another name of '''Sayla Mass'''.</ref> The kanji for Masumi's surname mean 'good world'. The kanji for her first name, Masumi, mean 'true' and either 'pure' or 'net.'

== Quotes ==

{{cquote|I guess I'm a bad kid after all...|Masumi, while crying, File 814 pg 16}}

== Trivia ==
[[File:M18-Sera.jpg|thumb|right|Movie 18]]
* Masumi is based on [[Natsuki Koshimizu]], a tomboy detective girl turned criminal who made her first appearance in the [[Volume 54#Detective Koshien Case|''Detective Koshien Case'']]. Since Natsuki had proven highly popular, but Aoyama couldn't recycle her as a protagonist, the character of Masumi was created instead.<ref>''Shonen Sunday'' #33</ref>
* When she was young she liked to read the "[[Night Baron]]" series, so she is fan of [[Yusaku Kudo]].
* Her catchphrase, "Case Closed" (said in English), is likely a reference to the English-language name of Detective Conan. It was later revealed that she first heard the phrase being used by her brother Shuichi after he solved a case, most likely inspiring Masumi to use it herself as well.
* Masumi owns an [[Vehicles in Detective Conan#Sera's Yamaha Artesia XT400|Artesia XT400]].
* In File 859, Masumi reveals that she has a second-older brother and that her oldest brother taught her Jeet-Kune-Do.
* Masumi speaks Queen's English.<ref>[[:File:Postcard2015 1.jpg]]</ref>
* In movie 18, Sera's breasts are mistakenly a little bit developed.

'''{{nihongo|Masumi Sera|世良真純|Sera Masumi}}''' is a high school detective in the manga and anime franchise ''[[Detective Conan]]''. She is the younger sister of [[Federal Bureau of Investigation|FBI]] agent [[Shuichi Akai]] and a practitioner of the martial art [[wikipedia:Jeet Kune Do|Jeet Kune Do]].

== Background ==
Masumi Sera is a high school detective and the younger sister of [[Federal Bureau of Investigation|FBI]] agent [[Shuichi Akai]] and shogi player, [[Shukichi Haneda]]. She is the only daughter of [[Tsutomu Akai]] and [[Mary]]. 17 years ago, her father, before he disappeared, instructed his family to hide in Japan, where Masumi later was born. Her oldest brother had prior to her birth left Japan to study in America, so they first got to meet each other when Masumi was six-seven years old. Although she grew up in Japan during her elementary school years, she moved abroad three years ago with her mother, presumably due to Shuichi infiltrating the [[Black Organization]]. Her other brother stayed in Japan. She has recently returned to Japan for some unknown reason. After meeting Conan, Ran, and Sonoko during a case, she transfers to [[Setting#Teitan High School (帝丹高校)|Ran's high school class]]. Masumi is skilled at [[Wikipedia:Jeet Kune Do|Jeet Kune Do]], a hobby encouraged by her brother Shuichi who mailed her instruction videos while in elementary school. She can fight on the same level as [[Ran Mouri|Ran]]. She seems to know that Conan is Shinichi and she had in fact met Ran and Shinichi sometime in their past. Currently she is living with [[Mary]], whom she calls "Mama", at a hotel. She claims that she is provided for by a rich friend of her late father, but it hasn't been revealed who it is. Every time they encounter the possibility of information on Mary getting out, they end up moving to a new hotel under Mary's order. While Masumi is eager to seek help from Conan, Mary is skeptical of him.
The three siblings has different last names. Sera is supposedly her mother's maiden name.

== Personality ==
[[File:691-15.png|thumb|Masumi beats a gangster in [[Yusaku Kudo's Cold Case]]]]
Masumi has a cheery, sociable, boyish personality<ref>Manga Volume 73, File 9, Page 3, "Let's hear your brilliant deduction!"</ref> and is well liked by her classmates at Teitan High. On their first meeting, Masumi fails to correct Sonoko's mistaken impression that she is a man and even makes it worse by declaring that Ran is "[her] type".<ref name=pronouns>The Japanese pronoun used is gender neutral and can refer to either males or females.</ref> Her rather boyish appearance - especially in relation with her flat chest - is a bit of a touchy subject to Masumi, who claims that her mother's bust size is rather well developed and keeps expressing her hope that someday her own chest size will similarly change for her.

Masumi is quite quick-minded, coming up with clever plans and adapting them to sudden changes rapidly. Masumi seems to be prone to dramatics like most detectives are, but perhaps to a lesser degree than [[Shinichi]] or [[Heiji]] as she bluntly says who the criminal is without preamble. On the other hand, Masumi is tough to the point that she is willing to risk all to achieve a successful conclusion of a case. In one instance, she purposefully lured a hostage-taker into a sniper's sight with a smile, hoping he would be shot without showing any apprehension about his possible demise.

Although she has crime scene experience<ref name=769p3>Manga Volume 73, File 7, pg 3: "A Detective Just Like You, Little Boy"</ref>, Masumi seems to be less skilled as a detective than Shinichi or Heiji, apparently missing a critical clue that was necessary to understand how the murderer's setup worked, although Conan opines that Masumi purposely made an error in order to test him. In some degree, she seems to like rivalry or contests to see who is the winner.

Sera's catchphrase upon the conclusion of a case is "case closed".

Sera shows a protective and caring side towards Conan, as seen in the Detectives Nocturne and in the beginning of the Red Woman case when she helps Conan up after falling, as well as having it made clear in the Haunted Hotel case that she was also clearly investigating Conan before they first met, as she knew he was a detective. It’s likely to believe that them being on the same bus was not an accident, which could even lead to be argued that she somehow hinted to them about the cake buffet so they would be on the same bus as her. It is safe to assume though she was, and possibly still is, investigating Conan.

Sera's way of referring to her parents as 'Mama' and 'Papa' indicates a privileges background.

== Appearance ==
[[File:Sera transfers.png‎|thumb|Masumi transfers to Teitan High School]]
At first, she wears a grey fedora that used to belong to Shuichi Akai and a dark jacket which gives her an androgynous appearance. When she transfers to Teitan High, she gets rid of her fedora and wears female clothing. Her hair is dark, wavy, and short; it doesn't even touch her shoulders. Even then, she is rather tomboyish; Genta mistakes her for a man, and Sonoko comments she has a petite figure. Later, Genta, Mitsuhiko and Hattori comment that her bosoms are rather small. Masumi also has an uneven tooth that shows when she smiles.

Masumi and her brother Shuichi presumably more closely resemble their mother than their father.

== Plot overview ==
=== Masumi's Introduction (Manga: [[Volume 73#Jeet Kune Do|768 - 770]], Anime: [[Deduction Showdown at the Haunted Hotel|646 - 647)]] ===
[[File:Sera_Kick.png|thumb|right|Masumi defends herself from Ran.]]
Masumi first met [[Sonoko Suzuki|Sonoko]], [[Ran Mouri|Ran]], and [[Conan Edogawa|Conan]] on a bus after she was mistaken for a [[Wikipedia:Groping|groper]]. After Sonoko declared Masumi was the groper, Masumi and Ran got into a fight, with Masumi's Jeet Kune Do holding even against Ran's karate. Conan and Masumi cleared up the misunderstanding by pointing out the real groper. Sonoko then mistook Masumi for a boy, an impression which wasn't helped by Masumi declaring that Ran was "his type".<ref name=pronouns/> Masumi and Ran both discovered they were heading to the same hotel, about which Conan is less than pleased.

Masumi finds out the hotel she is staying at doesn't have a room available and complains at the front desk. A man then falls into the parking lot and dies. Conan runs to the source of screaming while Masumi told the guard to watch the elevators before running to the roof. She immediately declares the crime to be a murder, giving her reasoning. She then reveals her name, Masumi, that she is a detective, and knows Conan is a detective as well. She also revealed before she knew Conan's name despite it not being mentioned in front of her, revealing that Masumi has been investigating Conan for awhile now.

[[Juzo Megure|Inspector Megure]] is not pleased to have another high school detective underfoot but lets Masumi and Conan investigate regardless. After listening to the suspect testimony, police observations, and examining the crime scene, Masumi announces that she has solved the case.

However, Masumi's deduction leaves out a critical detail; Conan is therefore forced to use Shinichi's phone to call his own, give Inspector Megure Conan's phone, and speak through Shinichi's as Shinichi using the voice-changer bow tie. Shinichi figures out the detail that had Masumi stumped, although a look she gives Conan as he runs off suggests her omission was possibly intentional, and once during the phone conversation she tries to trick Shinichi into admitting that he is physically present at the crime scene instead of being explained the details by Conan and Megure.

The following day, Masumi transfers to Teitan High School, surprising both Ran and Sonoko. She was rather popular at school surrounded by students asking her questions about herself.

=== Kogoro Detective Agency Hostage Crisis (Manga: [[Volume 73#Bomber's Request|771]]-[[Volume 74#Bomber's Request|774]], Anime: [[Hostage Situation at the Mouri Detective Agency|648 - 650]]) ===

==== Let's hear your brilliant deduction! (771) ====
According to Sonoko, Masumi has become very popular at Teitan high for being "cheery, sociable, boyish, and cute...and on top of that, she is a jeet kun do-using female detective!"<ref>Manga Volume 73, File 9, Page 3, "Let's hear your brilliant deduction!"</ref> One classmate compares her to [[Shinichi Kudo]] who has been taking a break from school. Masumi tells inquiring classmates that she has been staying in America with her parents since three years ago, but "rebelled" because she would rather live in her Japan where she was born and raised. She sneaks up behind Sonoko and Ran after school because she wanted to speak to Conan at the Mouri Detective Agency. At the agency, Masumi is unhappy to hear that Conan and the rest of Detective Boys are staying at Agasa's house and will be camping the following day. She settles for asking Kogoro if Conan is always at his side when he solves cases, hinting that she suspects Conan is the real brains behind "Sleeping Kogoro".

[[File:Sera slide_kick.png|thumb|left|Masumi sweeps out the Hostage Taker's legs]]
Just as Masumi is about to walk out the door, three female mystery writers and a man enter the agency. After a moment of confusion, the man suddenly fires a gun into the roof and takes the detective agency hostage. His demands are that Kogoro figure out which of the three writers killed his sister at a ryokan one month ago. The quick thinking Masumi sidles up to Ran and tells her to go for the man's gun after she takes his legs out. Sera's leg sweep sends the man to the floor, and Ran removes the gun from the man's hand with a kick; however, Masumi leaps back when the man reveals he has bombs strapped around his chest and will detonate them if they try to stop him.

Meanwhile at Agasa's, Haibara is angry that Conan used Shinichi's voice to solve a case around the suspicious Masumi. Conan's response is that Masumi is familiar somehow, like they have met before or she looks like someone, and Conan feels she isn't an enemy. Genta and Mitsuhiko told Conan they saw a high school student walking home with Ran, so the jealous Conan calls Ran's cellphone to hear about it from her.

The hostage taker man orders Ran to answer her phone, but Masumi snatches the phone away and says hello to Conan (who is shocked that Masumi is with Ran). Masumi then tricks the hostage taker and keeps the line connected so Conan can listen in by closing Ran's [[Yaiba#Characters|Sea Cucumber Man]] cellphone strap in between the screen and keypad of the the flip phone.

==== Nickname Rules (772) ====
Masumi asks a few insightful questions about the case; however the hostage taker man discovers Ran's phone is still connected. Under gunpoint, Masumi steps in front of Ran and takes the blame, but Conan, using Shinichi's voice, says he ordered Ran to do it. Masumi is mystified by why Shinichi is now on Conan's phone. Masumi meanwhile spots a glint of light across from the detective agency and declares that the case will come to an end without Shinichi's help.

==== Possible Sniping (773) ====
[[File:Sera773.png|thumb|right|Masumi surprised by Ran's attitude.]]
Masumi explains to Ran that she secretly kept the call to Conan connected so he could call the police and research into the case. While Masumi is still surprised that Shinichi was on the other end of the line instead of Conan, she had initially hoped that Shinichi would somehow be able to talk down the would-be-murderer. She suspects that Shinichi has already figured which one of the suspects is the murderer in the ryokan case, but Shinichi is unable to reveal the truth because the hostage taker would then kill the named culprit and then himself. Sera's plan changed when she noticed the lights from the police snipers on the building across from Mouri Detective Agency. She explains to Ran in detail the names and functions of the various police divisions responsible for hostage situations, and tells Ran in a roundabout fashion that this situation will end with the hostage taker being killed by the police.

Masumi launches a plan to bring the hostage taker into the snipers' range by telling him he should charge Ran's phone battery. Ran foils Sera's intentions by shutting the curtains, blocking the snipers' shot. To Masumi's utter astonishment, Ran tells her that she doesn't want to see anyone die in front of her and declares that "Shinichi won't allow anyone to die. He absolutely wouldn't!"<ref>Volume 73, File 11, page 13, "Possible Sniping." Shinichi then begins to present his deductions over the phone and Masumi wonders how he will manage to resolve this situation without bloodshed.</ref>

==== The book with unturned pages (774) ====
Masumi and Ran take the opportunity to disable the hostage taker when he loses his composure and grip on the detonator after Shinichi tricks him into believing his sister committed suicide. Masumi yells for the waiting bomb squad to secure the area. With the hostage taker arrested, Shinichi then reveals the true culprit. Masumi realizes the mistake in her deduction and explains the correct timeline of events before the murder. Sometime soon after the conclusion of the case, Masumi, walking with Ran and Sonoko speculates aloud that there must be some reason Shinichi left Agasa's before Ran could meet him there. She then exclaims that "due to what just happened, she really gets it", that Conan and Shinichi are on very good terms with one another, and that Ran "is tougher than Masumi thought". Conan isn't sure what to make of these last comments.

=== Video Site (Manga: [[Volume 74|775-777]], Anime: [[The Professor's Video Site|656-657]]) ===
[[File:Ai image.png|thumb|Masumi deletes Haibara's image]]
Masumi stops [[Genta Kojima|Genta]] and [[Mitsuhiko Tsuburaya|Mitsuhiko]] outside of [[Hiroshi Agasa|Agasa]]'s house to ask them if they are acquaintances of Professor Agasa. The topic of [[Shinichi]] comes up when she talks to Mitsuhiko and Genta about the prior hostage case. Mitsuhiko mentions that [[Ai Haibara|Haibara]] told them to keep Shinichi's involvement secret. After asking about Haibara, Masumi mentions that she saw Haibara in one of the professor's online videos. Next, Masumi asks who is currently living in the Kudo house because she saw the curtains shift slightly. The Detective Boys tell her that [[Subaru Okiya]] has been staying there since his apartment burnt down. Masumi cryptically comments with a smirk on her face, "And here I thought that someone had just settled in without permission...But it seems I was just getting worked up over nothing..." while looking up at where Subaru is hiding.

At the end of the case, Masumi is in her hotel room deleting various files. One of her deleted files was a still image from Agasa's video blown up to show Haibara reflected in Agasa's glasses. This indicates that she is not only keeping an eye on Conan but also on Haibara.
"Delete... Delete... For data, at least is an easy task to accomplish...", were her words while she was doing it.

=== East vs. West Rematch (Manga: [[Volume 74#East vs. West|778-780]], Anime: [[Conan vs. Heiji, Deduction Battle Between the Detectives of the East and West|651]]) ===
[[File:Sera FBI.png|thumb|left|Masumi thinks about the FBI]]
The case opens with Ran talking to Masumi about [[Heiji Hattori]] who is stopping by for a visit. Masumi is curious whether Heiji or Shinichi is the better detective. After Heiji is introduced to Masumi, Kazuha then calls Heiji and tells him that she is stuck at a restaurant because someone died and a foreigner [[Andre Camel]] is keeping everyone from leaving. Masumi proposes Heiji and Shinichi (via Conan's cellphone) have a deduction match. At the crime scene, Masumi becomes curious about the foreigner, Camel who secured the area. The police and Conan reveal Camel is an [[Federal Bureau of Investigation|FBI]] agent and Masumi takes interest. Meanwhile, Camel finds that Masumi looks familiar, but can't quite place why. He takes a picture of her and mails it to [[Jodie Starling|Jodie]] and [[James Black]] who are waiting outside. Jodie and James think Masumi resembles someone too, but only James Black correctly identified Masumi as female.

Meanwhile Masumi is busy helping with the case, asking questions and making comments about various deductions. Heiji nearly slips up with Conan's identity in front of her earning a pointed question from Masumi, but Heiji rescues himself by saying he thinks of Conan as Kudo when Conan gets smug have hearing Shinichi's deductions over the phone. Masumi doesn't seemed to be fooled though, her thoughts show that she seems to know Conan, not Shinichi, is the one solving the case while watching Conan come to his final conclusion.

Heiji reveals the case that brought him to Tokyo; he received a mysterious letter signed in the name of a person who was murdered in Karuizawa requesting an investigation. Masumi takes an immediate interest in the case and wants to tag along, but Heiji refuses saying that the people he is visiting are only expected five people. Masumi is peeved at being left behind.

When an old lady named Takae Kiritani comes, she claims that Kogoro has been helping her. Masumi asks what he does for her to which she replies that its small things like helping around the house. Masumi isn't seen again for the rest of the case.

=== Murder at Mouri Detective Agency (Manga: [[Volume 76|797-800]], Anime: [[Detectives' Nocturne|672-674]]) ===
[[File:Sera's motorcycle.jpg|thumb|right|Masumi in her motorcycle.]]
During a murder case at Mouri Detective Agency, after meeting Kogoro's new apprentice [[Rei Furuya|Tooru Amuro]], [[Juzo Megure|Megure]] comments that the number of detectives around Kogoro has increased again, referring to Masumi. Amuro takes interest in Masumi. Later, Kogoro and friends go over to a suspect's apartment. Masumi calls Ran after hearing about the murder on the news because she is worried about her and Conan. The call has an usual amount of static which alerts Amuro that there are listening devices present. Amuro abruptly hangs up Ran's phone on Masumi. Meanwhile, Conan intentionally gets himself kidnapped by the primary suspect. After Ran enables calling again, Masumi calls back immediately and is very upset because she was worried something had happened to Ran. Ran tells her that Conan has been kidnapped, and details to Masumi the murder at Kogoro's agency. In order to figure out where the kidnapper is headed, Kogoro and Amuro search the apartment and decide to go to the address of one of the other suspects.

Masumi arrives at suspect's home on [[Cars|her motorcycle]], but just misses Kogoro and the gang leaving. She hears the elevator descending and rushes back downstairs in time to follow Amuro's [[Cars|car]]. Meanwhile, the culprit has been driving around with Conan while Haibara has been directing Okiya's car towards them using the criminal tracking glasses. Okiya catches up to the kidnapper and relays what the car looks like to Kogoro. Amuro sees the suspect's car heading in the opposite direction so he quickly wheels around after it. Masumi, who has been following Amuro's car this whole time, u-turns after Amuro and continues chasing. Amuro gets in front of the suspect's car and stops it. The suspect gets out of the car holding Conan at gunpoint, but Masumi drives up onto the roof of the car. She swings her motorcycle around so that the rear wheel slams into the woman's face knocking her unconscious. With tears of relief, Masumi hugs Conan, happy he is safe. Amuro, Okiya, and [[Vermouth]] look on.

=== Meeting with Scar Akai (Manga: [[Volume 76|801]], Anime: [[Won't Forgive Even One Millimeter|675]]) ===
[[File:Sera 675.jpg|thumb|left|Masumi looking for Scar Akai.]]
Masumi is walking with Sonoko and Ran, and Ran is talking by phone with Conan. Masumi hears Haibara's voice in the background and becomes curious. She asks the two others what Haibara is like, and Sonoko says Haibara is like a woman in a child's body.

When Ran hangs up her cellphone, the topic switches over to [[Rei Furuya|Amuro]]. Masumi says to Ran she wants to meet Amuro because she never got a really good look at him from the last case, but Sonoko thinks she wants to meet Conan, instead. Ran says Shinichi and Conan are big fans of Sherlock Holmes. Masumi thinks about that she has known that for a long time.

Suddenly, Masumi sees [[Scar Akai]] in the crowd ahead. She runs after him, but she can't catch him. Ran wonders who Masumi was chasing, but Masumi replies she thought it was someone she knew, and silently appends in her mind that it would be impossible for the man she was chasing to be the person she thinks it was.

=== Mystery Train (Manga: [[Volume 78|818-824]], Anime: [[The Jet-Black Mystery Train|701-704]]) ===

Masumi takes a video recording of the suspects running so she can show it to the detective boys in order to ask them which one had the closest gait to the masked suspect from earlier, but she is intercepted first by Scar Akai in the hallway. She stops and angrily asks him who he is. Scar Akai simply replies that she hasn't changed, reveals his face to her, and refers to her by her first name, "Masumi". In her shock Masumi calls him "Shu-nii", signifying that Shuichi is Masumi's older brother. She questions Scar Akai about what happened, saying that she heard he had died. Scar Akai then tasers her unconscious, stating that he was hoping for that response. Scar Akai later is revealed to be Vermouth in disguise, explaining why he attacked Masumi.

=== The Blush Mermaid Heist (Manga: [[Volume 78|828]]-[[Volume 79|830]], Anime: [[Kaitou Kid and the Blush Mermaid|724-725]]) ===

Masumi accompanies Conan, Ran, and Sonoko to the location of Kaitou Kid's next heist: a museum where the Blush Mermaid, a gem adhered to the shell of a turtle as a last ditch effort by a an Italian actress in an accident at sea to save her turtle by encouraging someone to rescue it. Before checking out the museum, Masumi asks Ran if she saw a [[Scar Akai|strange man in black]] when she found the hat on the Belltree Express. After the group arrives at the room where the turtle is being held in a large aquarium, [[Ginzo Nakamori|Inspector Nakamori]] pulls Masumi's face to see if it is a mask worn by Kid. Annoyed by Nakamori's mistaken gender assumption and having her face pinched, Masumi knees him in the privates ostensibly to prove he isn't Kid. Masumi then runs off to the bathroom. Later, when Kid makes his move, Masumi is one of many caught in his trap: the rug on the floor is pulled up by strings so that it pins everyone standing on it to the front of aquarium. As soon as the rug drops, everyone sees the tank is empty except for a card left by Kid. This leaves Conan and Masumi quite dumbfounded as to how Kaitou Kid could have removed the turtle. Later, Conan reveals that Masumi is really Kaitou Kid, and he had made a critical error in his acting by assuming Masumi was a male. Kaitou Kid had locked the real Masumi bound and gagged in the men's bathroom after knocking her out with a stun gun. Upon gaining consciousness, Masumi escapes her bonds, rushes out of the bathroom, and gives a still disguised Kid a fierce kick to the face. After Kid escapes (due to Ran distracting Masumi by pointing out that everyone can see her underwear), Masumi is relieved that she at least managed to recover her hat, which she thinks is special because it somehow has the same feel as her brother Shuichi Akai's hat.

But whether or not our deductions are the same - lately I've been losing confidence in that regard...". When the recipient writes back "Who is he? I'd like an explanation!", Masumi takes a picture with her smartphone. However, the recipient's answer, "If it's him, there's no problem." reveals that he is familiar with Conan.

Masumi was revealed to be Shuichi Akai's sister on the Bell Tree Express after a confrontation with [[Scar Akai]]<ref name=821p16>Manga [[Volume 78]], File 4 (821), pg 16: "Mystery Train (Junction)"</ref> and while sleeptalking.<ref name=823p4>Manga [[Volume 78]], File 6 (823), pg 4: "Mystery Train (Releasing Smoke)"</ref>
[[File:Sera_and_Shuuichi.png|thumb|right|Masumi and [[Shuichi Akai]].]]
* Masumi has bags under her eyes identical to Shuichi Akai's.
* Masumi Sera's name is also incredibly similar to Mobile Suit Gundam character [http://gundam.wikia.com/wiki/Sayla_Mass Sayla Mass] ({{lang|ja|セイラ・マス}}, ''Seira Masu''). [[Shuichi Akai#Name origin|Shuichi's name is derived]] from Sayla Mass's older brother's name, Char Aznable.
* Conan said he has a feeling he had met her before. "''Somehow I feel like we've met somewhere before, it might be that person resembles someone I know, that's why the feeling that we've met before is on my mind...''"<ref>Manga Chapter 771: Let's Hear Your Brilliant Deduction! p.11</ref>
* [[Andre Camel]] and most likely [[James Black]] seem to recognize her from somewhere. On another interesting note, James was the first to recognize that Masumi was a girl. Everyone else thought that she was a guy when they first saw her. Since James was Shuichi's boss, he would most likely know that Shuichi has a younger sister and what she would look like.
* Masumi lived in Japan until three years ago when her family moved to America. This matches with the time when Shuichi was infiltrating the Black Organization. The family's move to America could be the FBI's attempt to protect them should something go wrong with Shuichi's mission.
* In Chapter 801, Masumi chased after [[Scar Akai]] who appeared while she was walking with Ran in front of the Mouri Detective Agency. Although, Scar Akai hid before she could find him, she told Ran that she had just seen "someone she knew".
* In Chapter 859, Masumi, when being asked who taught her Jeet Kune Do, answers that her older brother did. Consequently, Conan asks Sera: "But, didn't you say your older brother was dead?" This leads to Masumi remarking "Yeah... That's what I heard." also further supporting the theory that Masumi is in Japan to investigate her brother's death.

=== Hints that Masumi was not Bourbon ===
* In Chapter 801, Masumi chased after [[Scar Akai]] who appeared while she was walking with Ran in front of the Mouri Detective Agency. Although, Scar Akai hid before she could find him, she told Ran that she had just seen "someone she knew". She then thinks there is "no way it was possible" regarding the man she saw, which would make sense if she thought Shuichi was dead. This implied she wasn't Bourbon, since Bourbon believes he is the only one who can kill Shuichi, implying that Gin might have failed to do so. Hence Bourbon wouldn't think that it was impossible to meet Shuichi again in the street.

== Relationships analysis ==
=== Friends and family ===
==== Shuichi Akai ====
[[Shuichi Akai]] is Masumi's older brother. She didn't get to meet him until she was six-seven years old, because Shuichi went to study abroad before Masumi was born. At first meeting she was very shy, but she did make some pranks in an attempt to make him smile. Masumi refers to Shuichi as "Shu-nii", implying that they were close. Masumi seems to miss him after his supposed death. In the Blush Mermaid Heist, Masumi is shown to be fond of her fedora as she believes it has the same "feel" as Shuichi's old hats. Shuichi sent Masumi Jeet-Kune-Do training tapes while she was in elementary school. She watched these so many times while practicing that she wore them out.<ref name="876p2">Manga [[Volume 83]], File 4 (876), pg 2: "Romance Novelist"</ref> She describes her eldest brother as ''strong'' in contrast to her second - oldest brother.<ref name="859p6-7">Manga [[Volume 81]], File 9 (859): pgs 6-7: "Jeet Kune Do vs. Karate"</ref>

==== Conan Edogawa ====
[[File:EP671-674 25.png|thumb|right|Masumi hugs Conan after rescuing him in [[Detectives' Nocturne]].]]
Masumi is interested in [[Conan Edogawa|Conan]]'s abilities as a detective and has been gathering information on him and his friends. She appears to be certain that Conan is Shinichi Kudo. Despite her initial suspicious presentation, Conan felt like she wasn't a bad person and so didn't mistrust her. Conan at several points questions her if they've met before, but she denies this, once secretly thinking, "Now's not the time". The period in which such an encounter could have taken place is initially hinted to be somewhere before the three-year span of Masumi's sojourn in the United States, when she was in her preteen years.<ref name="Mang83">Manga [[Volume 83]], File 2 (874), pg 7-8: "Red Past"</ref><ref name="Mang86">Manga [[Volume 86]], File 1 (905): "The Truth Rises to the Surface"</ref>

It is later shown that she had met Conan/Shinichi ten years ago, when the Akai family had gathered on an undisclosed beach in Japan prior to Shuichi Akai joining the FBI. By chance, Shinichi and [[Ran Mouri|Ran]] had also vacationed there, and they all ended up as witnesses and investigators in a gone-awry flight attempt from a robbery. When Shinichi managed to make Shuichi laugh (something Masumi had miserably failed to achieve) with his intelligence, observation skills and some unintended jokes, Masumi, in her admiration for Shinichi, began to call him "wizard". It is quite possible that this meeting inspired Masumi to become a detective herself.<ref name="Mang92">Manga [[Volume 92]], File 2-4 (972-974): "A Chance Meeting at the Beach"</ref>

If Masumi really lived in England, instead of America, then it's possible that she saw the tennis match from the London case on TV and recognized Conan as Shinichi based on his proclamation as 'Holmes' apprentice'.

On several occasions, such as the dramatic conclusion of the [[Volume 76#Online Client|Online Client Case]], Masumi has displayed an intensely affectionate air towards Conan which somewhat transcends a mere "big sister" relationship.<ref>Manga Chapter 800: ''Online Client Case'' - "When Objects Collide"; Anime Episode 674: ''[[Detectives' Nocturne]]'' - "Bourbon"</ref> In fact, it is hinted during the [[Volume 83#Romance Novelist Murder Case|Romance Novelist murder]] and in the movie ''[[Dimensional Sniper]]'' that she may actually be entertaining a crush on Shinichi/Conan and hopes of initiating a closer relationship with him. However, the actual level of her feelings for him is yet to be publicly revealed. However it doesn't seem like she has anything against Ran and Shinichi's relationship.

==== Ai Haibara ====
Masumi has been interested in meeting [[Ai Haibara]] for yet unrevealed reasons and has been secretly gathering information on her. She also seemed to recognize [[Shiho Miyano]] in the video of her rescuing the [[Detective Boys]]. Haibara in turn feels uneasy around Masumi, especially in close contact situations though arguably it could also be due to Scar Akai's presence near Masumi. The reason behind her interest might be due to Haibara's resemblance with [[Mary]].

==== Ran Mouri ====
[[File:Ran and Sera and Wave.jpg|thumb|left|Ran hears sounds of rippling waves when she sees Masumi hurried away]]
Since enrolling at Teitan High, Masumi and [[Ran Mouri|Ran]] have become friends and often walk home from school together. Masumi has also declared Ran as "her type" when they first met as a sign of liking, though this ultimately led Sonoko, Conan and Ran herself to mistake Masumi for a boy.

At one point, Ran recalls having met Masumi before in the past, hearing the sound of "rippling waves" when the she sees the latter leaving, "as if some sort of magic were at work".<ref name="Mang86"></ref> It is revealed in a later story that she and Masumi had actually met 10 years before, when they were both still children, on a beach, where by happenstance she, Shinichi and the Akai family inadvertently became embroiled in the aftermath of a crime (see '''Conan Edogawa''', above).<ref name="Mang92"></ref>

==== Sonoko Suzuki ====
Since enrolling at Teitan High, Masumi and [[Sonoko Suzuki|Sonoko]] have become friends and often walk home from school together, with Sonoko describing Masumi as a popular girl who is "cheery, sociable, boyish and cute" and on top of that, a "Jeet Kune Do using detective", though she also teasingly remarks that the only thing "against Sera" is her flat chest.

==== Shukichi Haneda/Akai family's middle brother ====
Masumi appears to have a good relationship with her [[Akai family's middle brother|second-older brother]] and often consults him regarding information or deductions about the cases she faced, and also has a high regard of her brother's intellect, even considering the already sharp Shuichi as "strong" in contrast to her second older-brother.

==== Tsutomu Akai ====
Masumi's father was missing before she was born, so she never knew him. But she refer to him as 'Papa.

==== Mary Sera ====
[[Mary Sera|Mary]] seems very mature and cold while talking to Masumi. She also treats her more like a coworker than her daughter, as she always advises her what to do and switch hotels if any intel about Mary is leaked.She is also somehow stubborn as she declined Masumi's trust in Conan despite the latter's motive and pursuit of justice are geniune.

=== Black Organization ===
==== Rei Furuya ====
Rei first saw Masumi in Detectives Nocturne case and seemed to recognise her. They formally met in chapter 936 (Girls Band) at [[Café Poirot]]. Masumi felt like having met him and even asked him directly about that, but Rei said that was the first time they met. When Masumi talked about a friend of her brother who taught her play the guitar, Rei also seemed to know about that incident. In Masumi's flashback of that friend, a man who looked very much like Rei appeared, and Masumi once again wondered about it, to which Amuro replied that she took the wrong person.

==== Scotch ====
Sera recalled meeting Scotch 4 years ago. That was when Scotch was with Akai and Rei in a train station. Sera also remembered Scotch teaching her how to play the bass and though it was only 10 minutes, she seemed to enjoy it. Sera is not sure of Scotch's true identity or allegiance, but thinks that Scotch is Japanese and that Scotch is not the real name.

== Speculation ==
[[File:Sera Knowing Conan's Name.png‎|thumb|right|Masumi mentioning Conan's name.]]
=== Masumi met Shinichi and Ran when she was younger and knows Conan is Shinichi ===
* Masumi knew [[Conan Edogawa|Conan]] and [[Ran Mouri|Ran]]'s identities before they introduced themselves. She also knew that Conan is a detective.<ref> [[Volume 73]], File 6 (768)</ref>
* Masumi seems to know that Conan is the brains behind Sleeping Kogoro. Conan seems to think that he may have met Masumi before or that she resembles someone that he knows. He believes that she got the deduction of a case wrong just so that he would reveal himself. <ref> [[Volume 73]], File 9 (771)</ref>
* Conan realizes he met Masumi before because he finds her snaggletoothed smile familiar,<ref name=845p16>Manga [[Volume 80]], File 6 (845), pg 16: "Our Territory"</ref>
* Masumi admits that she has met Conan before, but she can´t tell him until "the time" comes.<ref name=846p16>Manga [[Volume 80]], File 7 (846), pg 16: "The Magic Lock"</ref>
* Ran has met Masumi as well because Masumi's figure as she runs away reminds her of "sounds of rippling waves, as if some sort of magic were at work."<ref name=846p4>Manga [[Volume 80]], File 7 (846), pg 4: "The Magic Lock"</ref>
* Masumi, asks Conan if he once met a girl "a long time ago and could never forget [her]"<ref name=876p11>Manga [[Volume 83]], File 4 (876), pg 11: "The Romance Novelist"</ref> and gets annoyed when he says he can't recall someone like that.
* Ran has a flashback to when she saw a younger Masumi, who is wearing a bathing suit, say, "You are a wizard, right?". Ran also feels that she has met [[Mary]].<ref> Manga [[Volume 86]], File 1 (905)</ref>
* The meeting occurred 10 years ago, as mentioned by Mary.<ref> Manga [[Volume 90]], File 5 (953)</ref>
* Masumi puts on a swimsuit similar to the one in Ran's flashback in order to jog Conan's memory, which results in him remembering her in that bathing suit as well, along as three other people, assumed to be her relatives. <ref> Manga [[Volume 91]], File 11 (969)</ref>

In Chapter 771, it is revealed that she also knows Professor Agasa, although she calls him "Professor what's his name". Although this could be explained away as her talking to Conan off screen and her just not remembering Agasa's name.

=== Identity of Masumi's middle brother ===
{{main|Akai family's middle brother}}

=== The Wizard ===
In a PS, [[Akai family's middle brother|Masumi's middle brother]] asks if she "has already met the Wizard?"<ref name=861p15-16>Manga Volume 81, File 11 (861), pg 15-16: "Just like Magic"</ref> Masumi's thought reply is "You could say so..." Later, Masumi "thinks aloud" that her reason for returning to Japan is to meet the Wizard once more.<ref name=874p8>Manga [[Volume 83]], File 2 (874), pg 8: "The red past"</ref> The identity of the Wizard is revealed in File 974 to be Shinichi.

==== Shinichi Kudo ====
Tellingly, Masumi turns towards Conan when thinking of the answer "You could say so". At this point Masumi seems to know Conan is Shinichi. If Shinichi was nicknamed "The Wizard" by Masumi and/or her brother because of what happened when he and Masumi met in the past, then the response is appropriate since she could only sort of meet with Shinichi, because Shinichi shrunk into Conan. It's possible that the event where Shinichi earned the nickname "The Wizard" was Shinichi and Ran's meeting with Masumi 10 years ago. When trying to remember Masumi, Ran specifically mentions "sounds of rippling waves, as if some sort of magic were at work."<ref name=846p4>Manga [[Volume 80]], File 7 (846), pg 4: "The Magic Lock"</ref> A "magical" incident, if it was Shinichi's doing, might have earned him the nickname. Ran has a flashback of a young Masumi saying "You are a wizard, right?".<ref> Manga [[Volume 86]], File 1 (905)</ref> Conan seems to have remembered meeting Masumi 10 years ago and is shown as a young Shinichi standing in front of a large wave.<ref> Manga [[Volume 92]], File 2 (971)</ref>

==== Someone else ====
At this point it is unlikely that the Wizard is anyone else. There is evidence that Masumi nicknamed the person who she calls Wizard, at a point in the past while Ran was nearby. If Ran was nearby, then this would have to have happened when they first met 10 years ago, meaning that the person must be someone who existed back then. The topic of the Wizard came up during a text conversation about Conan between Masumi and her middle brother, and her response to if she had met the Wizard again was "You could say so", which is more than likely implying that she is referring to Conan, and therefore Shinichi.

[[File:Akai's picture 338.PNG|thumb|right|The picture of the Detective Boys the mystery assistants captured]]

=== Masumi learned about Haibara from Shuichi's picture ===
Masumi initially had an interest in Haibara. This is strange because Haibara didn't exist prior to Shiho shrinking. The knowledge of Shiho should have been secret to her as well, because Shuichi Akai's infiltration of the Black Organization was a secret. If Masumi doesn't even know the details of her brother's death, why should she know about Shiho? Masumi may recognize Haibara from pictures of Conan and Haibara that Shuichi took back during the Vermouth arc. It is standard procedure in the US to send the personal belongings of the dead back to their families. If Shuichi mixed these pictures in with his own things when he took them out of his truck before meeting with Kir, it's possible they were overlooked when the FBI sent Shuichi 's things to his family. If Masumi was interested in finding out how and why Shuichi died, she would begin by researching the people in those pictures and those connected with them in hopes of finding clues.

== Name origin ==
{{nihongo|Masumi Sera's|世良・真純|Sera Masumi}} name comes from the [[Wikipedia: Mobile Suit Gundam|Mobile Suit Gundam]] character {{nihongo|[[Wikipedia: Sayla Mass|Sayla Mass]]|セイラ・マス|Seira Masu}}.<ref>[[Sherry's soliloquy|Sherry's soliloquy (2012-06-17)]], Gosho was referring to the revelation that Masumi is Shuichi's sister (Manga File 821): {{lang|ja|やっぱりアルテイシアだったのね・・・}} (So it was '''Artesia'''…). Note that "Artesia" is another name of '''Sayla Mass'''.</ref> The kanji for Masumi's surname mean 'good world'. The kanji for her first name, Masumi, mean 'true' and either 'pure' or 'net.'

== Trivia ==
[[File:M18-Sera.jpg|thumb|right|Movie 18]]
* Masumi is based on [[Natsuki Koshimizu]], a tomboy detective girl turned criminal who made her first appearance in the [[Volume 54#Detective Koshien Case|''Detective Koshien Case'']]. Since Natsuki had proven highly popular, but Aoyama couldn't recycle her as a protagonist, the character of Masumi was created instead.<ref>''Shonen Sunday'' #33</ref>
* When she was young she liked to read the "[[Night Baron]]" series, so she is fan of [[Yusaku Kudo]].
* Her catchphrase, "Case Closed" (said in English), is likely a reference to the English-language name of Detective Conan. It was later revealed that she first heard the phrase being used by her brother Shuichi after he solved a case, most likely inspiring Masumi to use it herself as well.
* Masumi owns an [[Vehicles in Detective Conan#Sera's Yamaha Artesia XT400|Artesia XT400]].
* In File 859, Masumi reveals that she has a second-older brother and that her oldest brother taught her Jeet-Kune-Do.
* Masumi speaks Queen's English.<ref>[[:File:Postcard2015 1.jpg]]</ref>
* In movie 18, Sera's breasts are mistakenly a little bit developed.
