CoAi

Ai x Conan is the het ship between Shiho Miyano/Ai Haibara and Shinichi Kudo/Conan Edogawa from the Detective Conan fandom.

Canon
Since birth Shiho is a member of a mysterious criminal organization that tries to eliminate the young detective Shinichi Kudo, using a substance she invented, the APTX4869. Members of the organization, including Shiho, search Shinichi's home to ascertain his death. The girl, however, during the second search, realizes that her clothes from when she was a child have disappeared and since one of the laboratory guinea pigs on which she had tested the substance had happened to rejuvenate, she correctly deduces that Shinichi is a child again. However, the scientist decides not to divulge her hypotheses to her accomplices and when the Organization eliminates her sister, she decides to betray the group and assuming the APTX4869 she becomes a child again. She thus takes refuge in the Kudo house, hoping for the help of Shinichi (who has long since assumed the identity of Conan Edogawa) and runs into one of the few people who know Conan's secret, Dr. Agasa to whom she tells everything. Shortly thereafter, the girl and the professor create a pseudonym for her Ai Haibara, who enrolls in Conan's school. Ai Haibara immediately sits next to Conan and knowing that he is there too, she accepts the offer to join the group of Detective Boys. The group, at the request of a school friend, begins to investigate the disappearance of a high school student.

Convinced that behind there is the mysterious organization that made him become a child again, Conan tries to send his friends away and investigate with an excuse, but Ai smachera the trick and so the children follow him. Eventually the group manages to find the kidnappers ... but it turns out they were simply a gang of counterfeiters. Conan is surprised by the little girl's ability to use the gun. But when she is scolded by Inspector Megure and she starts crying he tells himself that she is still a child. Conan is annoyed at having to take Ai home, but as soon as they are alone, the brunette reveals that she is the creator of the substance that made her rejuvenate, and that she knows that he is actually Shinichi Kudo. Finding out that she is in the Organization by the name of Sherry, and that she too is rejuvenated by the substance and declaring that Dr. Agasa is dead, Conan becomes frightened and curses her ... only to discover shortly after that Ai he just made fun of. Later the doctor tells him the whole story.

Ai states that since they are in the same situation, Conan can understand her, but he claims he does not identify with a criminal thing that appears to hurt the brunette. Conan eventually decides to let her live with Dr. Agasa, but despite her being the creator of the substance, she cannot create an antidote without data. However, a floppy disk she sent to her sister may contain what they need, so the two go with Agasa to retrieve it. The two immediately start making fun of each other and the detective does not trust the scientist.

Unfortunately, when they arrive at the house of the man to whom Ai's sister had sent the disk, they find him dead. The two suspect the Organization, but then Ai becomes convinced that it was an accident and tries to persuade Conan that it is so, but the confidence with which he claims that this is a murder disguised as an accident, displaces her. Eventually Conan proves it was murder, to Ai's amazement. Shortly after Ai, she bursts into tears asking Conan how it is possible that one with his deductive skills did not save his sister Akemi, a robber killed by the same man who made Conan rejuvenate, Gin, whom he had met shortly after becoming a child again. The girl bursts into tears on Conan's chest screaming because and the brunette thinks that for the first time Ai has shown him her true face.

Eventually the recovered CD is found to be unusable due to a virus and Ai comments that she and Conan will have to see each other for a long time to come. However, Conan stops considering her a criminal and when the Detective Boys go to watch a national team football match, Ai makes fun of Conan for his passion for watching the game. The brunette remains on the sidelines, for fear that a camera will film her, since the organization knew what she looked like as a child, but wanting her to enjoy the game too, Conan gives her his hat and takes her by the hand to the stands. Watching the game Conan comments that Ai never gets upset for any reason and tells her that he was ashamed to death to go back to elementary school, but that she seemed very calm. The girl replies that it was because she knew that he was in the class too, who was in the same situation as her. The scientist then thinks that Kudo is at the center of the project that the organization has been carrying out for more than half a century, but she does not talk about it with the detective. Conan later asks Ai how old she really is. As a joke, she tells him that she is much older than she is, but the speech falls because a bomber threatens to blow up the stadium. Eventually Conan manages to get the bomber arrested and Ai tells him she's eighteen, just one older than him and says she's just perfect for him. This is a playful flirtation that will become a habit between the two.

The Detective Boys for a series of circumstances are housed in a castle and Haibara declares that Conan is the only one able to find him. When the friend mysteriously disappears, Haibara is the first to deduce that he may be in trouble. Eventually Conan, rescued by another friend of theirs Mitshuiko and manages to stop a multiple murderer from killing Haibara and the other girl from the Ayumi group. The Detective Boys go to the cinema and find themselves watching movies of the monster Gomera, which Conan has already seen when he was really a child. Ai urges him to try to enjoy the movies anyway, so that he can rest his brain a little. However, the three films do six hours of screening, heavy for children and during the second film, Ai and Ayumi fall asleep resting their heads on Conan's shoulders. Ayumi is really a little girl, so the brunette is not embarrassed, but when Ai leans her head on his shoulder he is embarrassed. Shortly after a murder is committed and Ai comments that even that day Conan will not be able to relax, certain that he will want to solve the case. Shortly after while I'm in the bathroom Ai comments that she shivers every time she passes in front of a mirror that sends her back to her as a child and asks Conan if that's the case for him too. Conan reminds her that it was her concoction that she fell this way and Ai admits her responsibility by apologizing and noting that she must be heavy for someone like Conan struggling to find out the truth, being forced to lie to anyone. Ai's words make Conan understand the trick used by the murderer and he runs to do his checks thanking her. Soon after Conan solves the case. Ai has a terrible nightmare about Organization members and is still visibly distraught at school the next day. Conan notices it and as they return to their houses he tells her that she must not think that she is better than she disappears so as not to endanger the children and tells her that he will take care of protecting her.

Soon after Conan and Ai come across a black Porsche 356 A and Ai says that Gin (the Organization member who gave Conan the APTX4869) owns that kind of car. Since it is an uncommon model, Conan correctly deduces that this is Gin's car and after having broken into it he puts a bug in it and the two begin to tail Gin and his partner Vodka from a distance in Doctor Agasa's car.

Ai finds that they are doing something too dangerous, but Conan continues with the chase and discovers that the Organization plans to have a person killed by a member of theirs that Ai does not know, Pisco. Unfortunately Gin finds the bug and destroys it and found a hair of Ai, he deduces that it was she who placed it. Conan has at least discovered the place of the murder and decides to listen to Ai's suggestion and stop the chase, but to try to prevent the killer, even if he does not intend to take the scientist with him. In the end, however, Ai learned that Gin plans to use the substance she created decides to accompany her friend (who did not want to take it with him because he thought it was too dangerous for her) saying that it is his responsibility to have created that stuff and that she doesn't want Conan to consider her a killer again. But Ai is frozen in terror and Conan learns of her nightmare and the fact that he and the other Detective Boys have been eliminated by Gin in it, gives her his glasses to disguise her and tries to comfort her. Ai so calms down. The murder succeeds, and Ai tries to take Conan away as the arrived cops may recognize them and in any case the situation is dangerous, but Conan convinces her that he can locate the culprit. To drag his friend away, Ai takes him by the hand which will become a habit between the two in moments of danger. Shortly after, however, Haibara is kidnapped.

Conan manages to get in touch with her via the microphone and headphones plugged into the glasses he lent her. Ai realizes that she must have been kidnapped by Pisco and Conan looks very worried. The scientist begins to explain to Conan how the APTX4869 works because she is sure that by now the Organization has identified it and that therefore even if she manages to escape, she will not be able to stay with the professor anymore, and continue to help Conan and therefore decides to give all possible information to the friend. Conan, however, manages to buy her time and makes her drink Paikal, a Chinese liqueur that has the ability to temporarily (and only once) reverse the effects of APTX4869. Ai manages to download data on the substance from Pisco's PC, and tells Conan that when the Organization takes her away, he can take the disk, but the detective tells her it won't happen.

Using her adult body, Shiho manages to reach the roof through the chimney of a chimney, but unfortunately she finds Gin waiting for her and shoots her, luckily only wounding her. Conan arrives just in time to hit Gin in the back with an anesteric needle and thanks to her diversion, Shiho manages to escape by throwing herself back into the fireplace. Unfortunately, Pisco returns to the room just after Ai becomes a child again and Conan has to save her from him too, and succeeds. Luckily, shortly afterwards Gin kills Pisco to punish him for having sloppily committed the murder and leaving evidence of his guilt and does not discover that Shiho is back as a child.

Fanon
Ai x Conan is a very popular ship in Detective Conan fandom and is primarily Ran x Shinichi's rival. Many fans think Ran is too dumb to be with someone as smart as Shinichi and that their relationship is dull, while Aibara is definitely more detective compatible and more mature.
