Conan Edogawa and Ai Haibara
In Episode 223, it is revealed that Conan knows Haibara's true name, Shiho Miyano, but he never calls her that, despite her calling him "Kudo-kun".
 Relationship analysis
It is shown in several manga chapters and anime episodes that Haibara gives hints about liking Conan. However, whenever Conan asks her about it, she always claims to be joking. Fans think she is trying to hide her pain on the fact that he loves Ran. Conan watches out for Haibara's safety and tries to protect and save Haibara if anything happens to her. He also worries about her mental condition when the Black Organization is involved. Yukiko Kudo and Jodie Starling sense that Haibara might have strong romantic feelings for Conan. Haibara is usually the first to notice Conan's actions and she knows well what he is up to.
 (Episode 129) The Girl from the Black Organization and the University Professor Murder Case - Volume 18 File 6 ~ Volume 19 File 1
- Upon Haibara's arrival at Teitan Elementary School, Genta eagerly offers the seat next to him for her to sit in. But as Haibara walks towards the desks, she brushes right past Genta and takes the empty seat next to Conan, and in monotone says to him: "Nice to meet you." Shocking Conan, the only thing he can manage to say is: "Yeah..."
- After class is over, the Detective Boys try to catch up with Haibara in the hallway, wanting to ask her to walk home with them. Haibara ignores all of Ayumi's attempts to talk to her until she inquires about her address, to which she replies: "22 Beika Block, Second Street." Conan regards the address as familiar and remarks to himself that her house can't be too far away from where his is. Haibara then looks over her shoulder and smirks at him, again shocking Conan and causing a small blush to appear right above his nose. Genta notices and asks him if he "likes that stuck-up woman". Which Conan quickly denies.
- When Ayumi and Mitsuhiko are telling Haibara about the Detective Boys, she asks, "Edogawa-kun is in it too?". Shortly after, the Detective Boys come across a case, where a fellow classmate's older brother has been missing and wants to find him.
- After solving said case, and Ai fires a gun through a window, causing her to get a scolding from Inspector Megure, and starts fake-crying (impressively well) to get out of it. Conan walks Haibara back home to her house, while she is still crying. When Conan drops her off nearby her home, Haibara immediately stops crying and then starts talking about a drug called "APTX 4869". Conan is confused, as Haibara continues to ramble about the drug, how he took it, and how she did too. It is apparent that Haibara isn't just your average little girl. It is not until Haibara tells Conan that she's occupied Professor Agasa's house and that he's "not in this world anymore", that Conan begins to freak out. He tries to call Professor Agasa but does not get an answer, while Haibara smirks evilly in the background (she's got the upper hand, at the moment). Conan then leaves Haibara behind and sprints to Professor Agasa's house, hoping to find him safe.
- Later on, Conan, Haibara, and Agasa come across another case. One involving the locked-room-murder of a university professor. After Conan solves the case, Agasa and Conan decide to head back home. When Conan gestures for Haibara to come along, we see a tear roll down her face as she asks why he didn't help her sister. To answer a confused Conan's face, Haibara explains (still in tears) that Hirota Misami was a fake name her sister took from the now-deceased university professor, and Conan realizes that the same girl (from the previous episode) who died during the one-billion-yen robbery case. Haibara continues to shout at a stunned Conan, with all his deducing skills, he should have been able to see right through her sister's case. Haibara breaks down and falls on her knees in front of Conan and clutches his shirt and continues to cry into it. But Conan silently thinks to himself: "This is probably the first true face she's ever showed me."
 (Episode 130-131) The Stadium Indiscriminate Threatening Case - Volume 19 File 9 ~ Volume 20 File 1
Near the end of the second part of this case, Haibara stares off into the distance after Conan made a joke about her being 84 years old. She tells him "Ara, I'm actually only 18 years old, just perfect for you. Just kidding." before she stares off into the distance again.
 (Episode 136-137) The Old Blue Castle Investigation Case - Volume 20 File 10 ~ Volume 21 File 3
While trying to figure out a chess code at a castle where the Detective Boys are staying, Haibara walks up to Conan, bends down, looks down at his paper, and asks if he is happy because that is his favorite thing. Conan blushes slightly when she looks up at his face and answers "I guess so..." Immediately after, they were interrupted by Ayumi yelling, "Hey! What are you two doing!?" which was really directed at Genta and Mitsuhiko.
Conan Edogawa later gets lost, and when every one tries to look for him it starts raining. Haibara tells Ayumi to stop crying and that "Edogawa-kun isn't the type to make you worry. He'll come back himself." She then comments on Ayumi's bag and about not letting her tears enter it. Ayumi replies, "Hey how do you know Conan-kun so well..." Haibara replies, "Come on. Why do you ask?" "Is it because you like him, right?" Haibara, surprised, recovers by asking, "What if I do?" Ayumi replies, "Then...I'm in trouble..." implying that there will be a love triangle if she does. Haibara sees Ayumi is worried and does not want to trouble her anymore, so Haibara plainly states she does not have those kinds of feelings for Conan
 (Episode 138-139) The Final Screening Murder Case - Volume 23 File 1 ~ File 3
At the start of the second Gomera movie, Ayumi falls asleep and puts her head on Conan's shoulder. When Conan turns to Haibara saying he needs to use the restroom and asks her if she would switch seats, she puts her head on Conan's shoulder too, having fallen asleep as well.
 (Episode 156) Metropolitan Police Detective Love Story 2 - Volume 23 File 10 ~ Volume 24 File 2
- The episodes opens with Haibara and Conan in what looks to be an abandonned and empty room. Haibara tells him that she (possibly referring to Ran) has found out about his identity. When he asks her why she's telling him all this, she tells him that he can see into the hearts of the wicked, but he couldn't understand a woman's heart, then tells him she's been in love with him since she met him. We see Conan's face, but it doesn't appear to be at all surprised, and Haibara continues with: "I guess you didn't even notice... Kamen Yaiba-san." After Mitsuhiko yells out "CUT!", it is revealed that both Conan and Haibara were merely acting, and practicing lines for Teitan Elementary School's play, with Mitsuhiko as the director.
 (Episode 176-178) Reunion with the Black Organization - Volume 24 File 7 ~ File 11
- Conan and Haibara went to the Haido City Hotel to catch Pisco, a Black Organization member, before he kills someone using the drug that shrunk them, as ordered by Gin. During the entire episode, Haibara is seriously frightened of Gin because the night before she dreamed that he discovered her true identity and killed everyone she had contact with. She made a point to also confide to Conan that she dreamed that he was shot first, which symbolizes a great fear over any harm done to him.
- Also, while they are in Professor Agasa's car following Gin and Vodka to the Haido City Hotel. She seems to be pleased by Conan's decision to stop Pisco from murdering someone (rather than just concentrating on Gin, Vodka, and the drug) and says, "Oh, what a strong sense of justice you have" with a proud smile. Because of his decision to do the right thing, she follows him into harms way knowing that she could be murdered immediately (because Gin can recognize her using only a strand of her hair) and enters Haido City Hotel against her premonitions.
- After Haibara says, "Maybe if I had been killed by the organization back then, there would be less hassle for everyone," Conan cuts her off by giving up his glasses (the only thing preventing people from recognizing him) and putting them on her to make her feel safer. After they have an encouraging conversation about his action's similarity to Superman/Clark Kent's disguise, Haibara turns away bashfully and thanks him. He looks at her and says somewhat sarcastically "You really aren't too adorable."
- After Haibara shrinks back to child size, Conan puts his jacket on her naked body and carries her from the fire before Pisco and Gin can discover them.
 (Episode 190) The Desperate Revival ~The Third Choice~ - Volume 26 File 2
While Conan was lying in a hospital bed after a blood transfusion, Haibara snuck into his room and held a gun at him. She told him that the Black Organization would accept her back if she killed him and everyone else related to him. She then pulled the trigger, but it turned out that it was a fake gun that shot red roses from the barrel. Symbolically, red roses represent love or passion, suggesting that Haibara might have romantic feelings towards Conan.

When asked by Conan (who has reverted back to Shinichi thanks to a prototype antidote) why she would go so far to help him, Haibara suddenly shows a surprised expression, as if some secret has been revealed.
 (Episode 230-231) The Mysterious Passenger - Volume 29 File 3 ~ File 5
Haibara was petrified because she felt a familiar and scary presence from the Black Organization around. (She was right because Vermouth was disguised as Dr. Araide at that time) When Jodie asked Conan for her name, she grabbed onto his hand desperately and he understood her fear, simply saying she was a random girl he happened to sit next to.
At the end of the second episode of The Mysterious Passenger, Haibara chose to stay on the bus (which contained a bomb) in an attempt to commit suicide so that she wouldn't have to worry about her future or the Black Organization anymore. Conan rushed back into the bus, risking his life to save her. They jumped out of the bus, but Conan was injured in the process. He put some of his blood on Haibara to give the police a reason to send her to the hospital, possibly as a way to keep an eye on her. It is also noted that Conan suspected that a Black Organization member was onboard the bus, so he tried to send her away. As Haibara got in the police car, Conan told her not to run away from her destiny.
 (Episode 233-234) The Evidence That Didn't Disappear - Volume 29 File 6 ~ File 8
Haibara was in a miserable mood throughout the two episodes. However, Ayumi, Genta, and Mitsuhiko cheered her up and Haibara was happy again. As she was smiling, Conan makes a comment saying that she should continue to smile like that because that makes her look like a child. She blushes from the comment until Conan says the wrong joke that she was 89 years old (she corrected him that she is 84 years old with scorn).

 (Episode 294-295) The Smash of Determination and Love
At the beginning of the episode, Conan notices that Haibara, who usually does not participate in their trips, is acting a bit odd by deciding to come along. Conan comments, "I wonder what could have provoked you to come this time". Haibara says that she's not really interested in the trip itself, but just wants a place to focus on her reading, adding, "Besides, you can't protect me if I'm not with you, right?". After the case, Conan and Haibara has to run laps for missing the semi-finals. When Conan has three laps to go, Haibara catches up to him and says, "I'll run with you." However, right after that, Ayumi and the rest comes up to them and runs the laps with them
 (Episodes 335-336) Secret of the Tohto Film Development Studio - Volume 41 File 4 ~ File 6
- Episode 335, Conan's mother, Yukiko, tells him that he seems to be popular with girls. Conan automatically assumes his mother is implying Ayumi likes him, and he was already aware of such, but Yukiko replies saying that not only Ayumi but Haibara too, saying: "She's looked your way about 10 times already," and continues: "There's only two reasons for a girl to look at a boy like that: he has something on his face or she likes him." Conan is shocked and insists she'd probably only been looking at him to see how the "test subject" for APTX 4869 was doing. Despite this, Conan later tests Haibara, otherwise.
- Before Yukiko left the Detective Boys, Conan and Haibara she's quick to remind Conan to: "never leave her side," before she drives off. To which Conan irritably replies: "I know, I know."
- Later that night, the Detective Boys, Conan and Haibara share a bed for sleeping. Conan and Haibara are sleeping side-by-side. When he is unable to go to sleep because of Genta and Mitsuhiko's loud, audible questions, Haibara calmly reminds him: "it can't be helped; they're just kids, not like us." Conan then takes this opportunity to ask her a question, as the scene grows quiet. Conan solemnly closes his eyes as the fringe on his hair shifts downward his forehead he asks if he can ask her something. She does not reply verbally but turns her head around, as she had her back to him before, to listen. Conan then asks: "Is there something on my face?" with something of a confused face. Haibara responds with a similar look, but appears to be dumbfounded instead.
