Ai Haibara

Ai Haibara is one of the main characters from the Detective Conan anime and manga.

A young girl whose true identity is Shiho Miyano, aka "Sherry" of the Black Organisation. She is the genius chemist who created the APTX-4869 drug that turned Shinichi into a six-year old boy. After she is imprisoned by the Black Organisation for being related to the traitor, Akemi Miyano, Shiho attempted suicide with a dose of APTX-4869 but was instead de-aged as well. Using her newly-shrunken body to escape and go into hiding as "Ai Haibara", Shiho is taken in by Shinichi's next door neighbour and uses her condition to live out the innocent childhood she never had. She joins the Detective Boys as a way to make amends for her past crimes, and works on an APTX-4869 antidote for Shinichi.

Appearance
As a child, Shiho has a short bobcut light-brown hair and has blue eyes.

Personality
Shiho has a sang-froid, mistrustful, sarcastic, cold attitude, and often reminds others about the darker side of reality and human nature. 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". 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.

Shiho 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.

While she generally accompanies her fellow Detective Boys to soccer matches played by the Tokyo Spirits, Haibara herself is a fan of Big Osaka in general and of the player Ryusuke Higo in particular, especially since the latter has likewise abandoned a "black organization" (Noir Tokyo) after the team had betrayed him and had remained an outcast in public opinion for a time. 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.

In the OVA A Secret Order From London, Haibara reveals to Ayumi that she likes sandwiches with a mixture of peanut butter and blueberry jam, from her schooldays in America. 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.

Trivia

 * According to Agasa, Ai Haibara's name comes from Cordelia Gray (the character in her name means "ash") and V.I. Warshawski (V.I. upside down = "Ai"). Although Agasa suggested she use the kanji (love) for "Ai", she preferred to use the kanji (sorrow).
 * Her US FUNimation name, "Vi Graythorn", has similar roots.
