Ai Haibara

Ai Haibara, real name Shiho Miyano, is the creator of APTX 4869, the pill that shrunk Shinichi Kudo into Conan Edogawa, and a victim of it herself. Formerly Sherry of the Black Organization, she is on the run from them and lives with Professor Agasa. She is also one of the few characters who know that Shinichi is Conan. Haibara has a calm and cool personality, sarcastic wit, and high intelligence. When freshly escaped from the Black Organization, she was cynical and pushed others away. Haibara has since defrosted by embracing her new child life and has established strong relationships with the Detective Boys, Agasa, and Ran. As Ai Haibara, she speaks and acts older than she is supposed to be, which results in the Detective Boys referring to her as "cool" or "mature". This is emphasized by her impressing general knowledge, even in areas without relation with sciences (such as theology or history); and on occasion she is so forceful and demanding that she can stun adults several decades above her current physical age into submission. Despite her jaded demeanor, she can be kind and caring, though usually more to animals than people. Haibara tends to be quiet, though this may be due to her caution to keep herself hidden from the Black Organization. She considers Conan and the Detective Boys the first real friends she has ever had, and is even willing to sacrifice herself just to ensure their safety. Indeed, she considers herself as a threat for them, since the Black Organization will most likely eliminate all of them once she is found. That is why she describes herself as "dangerous and not like the others". Haibara is generally a loner and misses her older sister, Akemi, greatly (in the film Countdown to Heaven, she would call her sister's old apartment just to hear her voice on the voicemail). Her greatest fear is being caught by the Black Organization, and she is especially terrified of Gin and Vermouth. She tries to keep Conan from doing reckless things that may give away their identity, though often she is surprised by his actions which usually result in gaining the information he needs while also keeping their identities secret. However, whenever Conan is reckless in regards to keeping his identity from Ran, Haibara is the one who plans ahead in order to keep him from being revealed. Because she occasionally works overnight on the antidote for the APTX 4869, she tends to be tired quite frequently, causing Conan to call her an "evil-eyed yawny girl" on one occasion. Despite spending most of her time alone at the lab, Haibara shows excellent understanding of reading people's mind. Examples include Haibara deducing that Ayumi had a crush on Conan, figuring out Conan was about to tell his identity to Ran, or understanding the anger of Kobayashi when confronting Inspector Shiratori. Thanks to this ability, Haibara can remind Conan about the situation and make him act appropriately, not to reveal his identity. In the OVA A Secret Order From London, Haibara reveals to Ayumi that she likes peanut butter and blueberry jelly sandwiches, from her schooldays in America. She has also mentioned that she only make it with "American peanut butter and jelly exclusively sold in international grocery store". However, since Professor Agasa caught her eating one of these sandwiches, especially since Haibara was on her part constantly pestering him into eating low-calorie foods only, she had to abandon that habit for a while.
