File 852 - Whereabouts of Shuichi Akai

  Show spoilers »

The culprit is Yoriko Danno. She wanted to avenge her son's death. Yoriko was pickpocketed by Ikuyo one year ago, and she lost her car keys which were placed inside the stolen purse. Because she couldn't open the car without them, her son who has asthma was locked inside the car for several hours. When he got sent to the hospital, it was already too late and he died. So Yuriko researched about that pickpocket on the Internet and hung out at places where she frequently appears. Tohei Benzaki turns out to be Bourbon in disguise, while the pregnant woman is actually Vermouth, who is there to assist Bourbon.

Steamy Relations

File 856 - Adultery Investigation

As Conan walks down the street, he recalls his conversation with Inspector Takagi, who had pointed out inconsistencies regarding Tohei Benzaki—one of the hostages from the Teito Bank robbery. Conan now suspects that Bourbon and Vermouth recently posed as the Benzaki couple. However, he is unsure whether this is a trap set by the Black Organization or exactly what the two might have observed. He calls Ai to ask if she sensed the Organization's presence during the cherry blossom festival, but she says no. While he is on the phone, Conan is being watched by Bourbon.

Later, Conan and Ran are waiting in the lobby of an apartment complex to meet Eri Kisaki for a meal once she finishes a consultation with a client. While waiting, Conan feels like he is being watched and hears the sound of a camera shutter. It turns out that Masumi has been taking photos of Conan, as she is also in the building for work. She has been hired by Rumi Kitao—the older sister of a classmate from another class—to vet Kenya Settsu; Rumi intends to introduce him to her parents as her future fiancé. The couple is also in the lobby, as Kenya plans to meet his ex-girlfriend, Waka Hashitani, to part ways amicably. After Eri calls Ran to say she will be late, Ran—at Masumi's request—approaches Rumi and Kenya. As Masumi had planned, she manages to secure the seat originally intended for Rumi's sister at the planned lunch. Masumi wants to put Kenya's loyalty to the test; Rumi catches on to the plan thanks to a signal from Masumi and agrees to go along with it.

Since Waka has not yet arrived, Rumi and Ran decide to check on her and head to her apartment. They manage to get inside using Kenya's spare key. When Rumi's phone rings shortly afterwards, Ran initially searches for Waka alone and eventually finds her unconscious in the bathroom. While Ran tries to speak to her, she too loses consciousness.

File 857 - My Deduction

When Ran regains consciousness, she finds herself in the anteroom of the bathroom in Waka's apartment. Conan, Masumi, and the police — led by Inspector Yokomizo — are also present. They inform Ran that Waka, whom she had previously found seemingly unconscious in the bathroom, has been bludgeoned to death. After Ran fainted, Rumi had also entered the bathroom but lost consciousness as well due to the chloroform present in the room. Half an hour later, they were discovered by Rumi's friends Kenya and Mitsuaki, who also notified the police.

Upon closer examination of the crime scene, Conan notices that Waka was already wearing mascara; Inspector Yokomizo also finds the condition of the body unusual. He summarizes the statements given by Waka's friends. His suspicion falls primarily on Kenya and Mitsuaki, as Kenya possesses a spare key to the apartment, while Mitsuaki had the opportunity to steal Waka's key the previous evening. However, Rumi also used to have a key to the apartment, having lived there for a time. Masumi is able to confirm, though, that Rumi had remained in the entryway the entire time before going to the apartment with Ran, and thus had no opportunity to commit the crime. She reveals herself to be a detective and explains her assignment — much to the annoyance of Rumi's friend Kenya. At the same time, she considers the possibility that there might be another explanation.

Meanwhile, Conan asks Rumi about an old photo of her and her friends in which they are all wearing glasses; she explains that they all use contact lenses now. Conan then asks Ran if Rumi unlocked the door and if there were any issues doing so; Ran says no. When he attempts to pull his wallet from his trouser pocket, he drops it, and the coins roll across the floor. Conan asks Kenya and Mitsuaki to pick up the coins for him. In the process, he notices something — and is certain that Masumi has noticed it too — but she is currently on the phone with an unknown person, checking whether her conclusions are correct.

File 858 - A Problematic Deduction

Inspector Yokomizo continues to suspect Kenya and Mitsuaki of Waka's murder. When Kenya accuses Rumi of conspiring with Masumi to kill Waka while simultaneously fabricating an alibi, Masumi intervenes in the conversation. She outlines a scenario of how Rumi could have committed the crime: since Ran did not know Waka and visibility in the bathroom was obscured by steam, Rumi could have posed as the late Waka. After Ran lost consciousness from the chloroform, Rumi could have quickly left the bathroom and subsequently killed Waka.

Following Masumi's deductions, a police officer enters the room and informs Inspector Yokomizo that Rumi's fingerprints have been found on the chloroform bottle. Just as he is about to arrest Rumi, Ran points out some flaws in the reasoning. Conan — who had previously called her on her mobile phone using Shinichi's voice — now intends to clarify the true sequence of events, as the actual culprit had aimed to incriminate Rumi. Given Waka's skimpy clothing, it seemed as though only a woman could have assumed the victim's role — but this conclusion is too obvious. However, the fact that the victim was lying with her back exposed creates a contradiction in the theory so far: Rumi could not have known for certain whether she herself or Waka had a birthmark on her back — a detail that would have revealed to Ran that they were two different people.

The actual culprit is Rumi's boyfriend, Kenya Settsu; he had staged the entire incident to cast suspicion on his girlfriend. He killed Waka during the brief period he had left the lobby and arranged the crime scene accordingly. However, because Waka fought back when he tried to sedate her, he lost one of his contact lenses. Waka managed to retrieve it and put it in. That is why Kenya had not handed the coins to Conan earlier; he had already dropped the key in the lobby while trying to give it to Rumi. Since his fingerprints were on the lens, he is consequently identified as the culprit.

Later, Conan and Ran talk to Eri in the lobby. She tells them that she had previously observed Masumi on a call with someone who was evidently her brother.

Bumper Brawn

File 859 - Jeet Kune Do vs. Karate

On a heavily raining day, Conan, Ran, Sonoko, Sera and Kogoro go bowling in Gunma. Makoto, who has just returned to Japan, is also coming, and Sonoko plans to introduce him to Sera. But, Sera is very curious, she quickly loses her patience, and cuddles Sonoko in an attempt to make her tell her who the person is. As she does so, Makoto arrives, and since he mistakenly thinks that Sera is a guy getting too intimate with his girlfriend, puts his hand on her shoulder forcefully and gives her a death stare. Sera takes the death stare as a sign that Makoto is challenging her, and a fight ensues. Sonoko is delighted by this scene, as she has been waiting for it for a long time; this means that Ran has to step in to stop the fight in the end. After resolving the misunderstanding and introducing themselves to each other, Makoto asks who taught Sera Jeet Kune Do, as he has learned from their brief engagement that Sera is quite good at it. Sera cites her brother (who, according to her, is three times as good as she is at it) as her teacher, which confuses Conan, who thought that her brother is dead. Sera clarifies that she actually has two elder brothers: the older between them taught her martial arts, and is probably dead; the younger one is whom she called during the last case. Sera continues to say that her second brother looks like their father (unlike her and the first brother), is very intelligent, and sometimes discusses cases with her. In addition, he has very important work to do, and thus is reluctant to share with Sera the specifics of his work and where he lives. Sera concludes by saying that her second brother thought that her deduction in the last case was problematic (which it was), and that Conan could rectify it for her. Conan replies that all credit should go to Shinichi; Sera smiles at him upon hearing this, which makes Conan think in dismay that maybe Sera already knows his identity.

At this moment two middle school teachers (named Michiko Monna and Sunami Masaki respectively) approach Makoto to apologize for their fellow teacher (called Masahiro Tanba) having picked a fight with him after drinking. Makoto says that he does not mind, and learns that Tanba is not injured by his punch and is now sleeping in their car. He then joins Sonoko and her friends in bowling, but as he is about to throw the bowling ball he hears Sonoko cheering for him. This makes Makoto blush and becomes a distraction for him, and the ball ends up causing massive vandalization instead of hitting the pins. Makoto thus smiles awkwardly, saying that bowling is not for him; combined with the fact that he still suffers from jet lag, he decides to go rest in Kogoro’s rented car.

A while later, Monna, out of worry, leaves the bowling alley to check on Tanba. When she returns she says that Tanba is missing. Kogoro offers to help (not because he suddenly turns warm-hearted, but because he has been bowling with the two teachers for a while and finds them quite attractive), and Conan and company join in. After a thorough search of the surrounding area, Masaki finds Tanba dead in a small porta-potty in the bowling alley’s parking lot. There are signs that he has been drowned somewhere else and dragged to the porta-potty; and since Tanba was a tall and robust man, Sera deduces that unless several people were involved in transporting the body, the murderer must be extraordinarily strong. Could it be the case that Makoto is the murderer, given that nobody knows where he was during the last few hours (Makoto did not rejoin the group until after the discovery of the body), and he just had a fight with Tanba?

File 860 - The Smell of Kerosene

The rain stops as Yamamura arrives to investigate; he is informed by Kogoro that they actually searched the parking lot two times. During the first search there was no sign of Tanba, for which the searchers went to the bars nearby to look for him, and stayed in those streets for an hour. After yielding nothing there either, they went back to the parking lot, and this time the body appeared. Yamamura asks whether they looked into the porta-potty specifically during the first parking lot search, and the two teachers respond that they did not enter, because there was a sign reading “OUT OF SERVICE”, and the door was padlocked.

Presently a subordinate of Yamamura tells him that the victim died around 5:30, which was when the first parking lot search ended. From these pieces of information, Yamamura deduces that Tanba was removed from their car before Monna went there to check on him, and that after everybody had gone to look for him in bars, the murderer drowned him and dragged him into the porta-potty. Yamamura then asks whether anyone holds a grudge against Tanba, which allows him to quickly learn that he fought with Makoto just a few hours before his unfortunate end. Since Makoto has no valid alibi, Yamamura determines that he is guilty and swiftly handcuffs him. Kogoro tells Yamamura that pronouncing Makoto to be guilty with so few clues is rather inappropriate, but the strongest protest of all comes from Sonoko. She puts herself between Yamamura and a confused Makoto, and declares (while blushing) that someone as outstanding and caring as Makoto must be innocent. This does not convince Yamamura, but after learning that Tanba was electrocuted by a stun gun before being killed and that Makoto is a national karate champion (who obviously has no need for a stun gun for self-protection), he agrees to take the handcuffs off Makoto; he also complains that Makoto should have told him that earlier (Conan remarks that Yamamura already knows Makoto from Sonoko’s handkerchief case).

The investigation continues (more accurately, Sera and Conan continue the investigation, as it starts raining again and Yamamura and Kogoro have gone inside the bowling alley to take shelter). They learn that due to land subsidence in the area, water would accumulate around it whenever it rains; this seems to be a major clue. In addition, the two detectives notice plenty of mud on the lower parts of the wall of the porta-potty, find evidence that duct tape once sealed the door and covered the ventilation grills located at the back of the porta-potty (curiously, the ventilation grills near the bottom of the door were not affected), and realize that kerosene was a part of the murderer’s trick. These clues allow them to see that it is possible that Tanba was actually drowned in the porta-potty.

Having inspected the porta-potty fully, Sera and Conan go indoors as well. There, they are told that a long, clear mark is present on the lower abdomen of Tanba’s body, which might mean that the murderer transported Tanba by grabbing his belt. They also learn that the police have found in the rubbish bin beside the porta-potty a wet towel and four cans burnt around the tear line and with odors resembling kerosene. Upon seeing these, Conan immediately rushes out, believing that there is one critical part of the porta-potty that he previously ignored. Sera quietly follows him there, and both find that a large portion of the ceiling has been burnt. This is the last piece of evidence that they need, and now both have a theory of what happened. However, partially because of her failure in the previous case, Sera is not very confident in herself, and so sends her deduction to her second brother to ask for his nod, and mentions that “he” (i.e. Conan) has gotten to the bottom already. The brother does not comment on her deduction, and instead asks who the “he” refers to. Sera thus sends him a photo of Conan, expecting the brother to be surprised, but she ends up being the one surprised: the reply of her brother is “if it is him then there is no problem”. Sera does not understand why his brother knows about Conan.

File 861 - Just Like Magic

  Show spoilers »

Conan goes back into the bowling alley and, after some efforts, convinces Kogoro and Yamamura to go outside for an “experiment”. They head to a porta-potty that Conan has asked Yamamura’s subordinates to set up (in the name of Kogoro, of course); similar to the original one, due to subsidence, a lot of rainwater accumulates around it. Kogoro is annoyed by the fact that someone has been doing things that he does not even know about in his name, but before he can protest Conan tranquilizes him and announces that the experiment will begin, with Yamamura being its subject. Yamamura accepts, albeit reluctantly, as he does not know what to expect. Conan says that it is simple, and that he just needs to sit on the flush toilet of the porta-potty and wait. He then requests Sera to cover the ventilation grills at the back with duct tape, place four cans partially filled by kerosene onto the shelves of the porta-potty, stuff a piece of paper inside each and ignite them. After this, Sera is to close the door and seal it with more duct tape, and the preparation is done. In the next few minutes, as the burning continues, the pressure inside the porta-potty increases. Eventually, oxygen runs out, the burning stops, and the air pressure reduces rapidly as temperature drops, causing water to be sucked into the porta-potty through the ventilation grills on the door. In this way, the volume of water inside drastically increases, and while at the start of the experiment it reached the lower portions of Yamamura’s legs, now he finds himself completely submerged and unable to breathe. If Sera had not removed the duct tape and opened the door in time, Yamamura would be dead in minutes.

As Sera finishes explaining the physics behind the murder scheme, she turns to Sunami Masaki, and declares her to be the murderer. She conjectures that on the way of taking the drunk Tanba back to their car, Masaki told him that she had forgotten the car key so that she could take him to the porta-potty for “temporary shelter against the rain”. Once Tanba was inside in a sitting position, Masaki would stun him and tie his belt to the flush toilet (in this way, if Tanba tries to stand up to avoid being submerged in water, he will be unable to do so, and a mark will be left on his abdomen as he attempts). Then she set up the cans (without igniting the paper yet), padlocked the porta-potty, put up the sign to dissuade others from approaching, used duct tape to cover the ventilation grills at the back and blocked the entrance to the drainage system nearby with a towel. With everything prepared, Masaki now could return to the bowling alley. She would claim that Tanba was asleep in the car, and encourage Monna to check on him so that she would notice that he was missing and ask her to search for him. This would give her a reason to return to the parking lot. Now that there was enough rainwater around the porta-potty, she would ignite the four pieces of paper (this is why the ceiling appeared burnt), seal the door with duct tape, remove the padlock and the sign and leave Tanba to die. Meanwhile she would convince Monna to head to nearby bars to continue the search so that she would have a valid alibi.

Sera continues stealing Conan’s show time and says that since this alibi will work only if the body is discovered soon after death, the murderer will be desperate to come back as soon as possible. Additionally, under this scheme, the murderer has to make sure that she (or he) is the one to find the body first, because the duct tape and the cans have to be disposed of, the entrance to the drainage system must be unblocked to remove water, the rope used to tie Tanba to the flush toilet must be cut and the completely soaked toilet paper needs replacement (if any of these fails, the police might think that there is something fishy). In other words, that Masaki discovered the body is proof that she is guilty. Another piece of evidence is as follows: since no duct tape was found in the rubbish bin, it must have been flushed down the toilet. Following this line of reasoning, Sera and Conan asked the police to look into the sewage system for retrieval. They have successfully done so, and, unsurprisingly, they have found Masaki’s fingerprints on it (as it is almost impossible to scrape duct tape off a surface with gloves on).

Knowing that the evidence the police have is unequivocal, Masaki admits that she killed Tanba. The motive is somewhat convoluted: Tanba was engaged to a good friend of hers, but since his parents had already picked another girl and were vehemently opposed to their marriage, the desperate couple decided to commit suicide together. However, when they were actually standing on the cliff and looking down at the bottomless ocean, Tanba was scared and, while his lover jumped off and eventually drowned, he stayed on the cliff cowardly and failed to kill himself. Masaki could not tolerate such behavior, and she also wanted the two to rejoin, which prompted her to do it herself.

The case is therefore solved. Presently Sera receives another message from her second brother, and while Aoyama does not show us, the readers, the main body (although it can be inferred that the brother is explaining why he knows Conan), he does kindly allow us to see the P.S. It reads “have you seen the wizard already?”, to which Sera responds “you could say so” as she looks at Conan with a smiley face.
