Ai Haibara
Ai Habara is the girl who made APTX 4869 - the medicine that has shrunken Shinichi Kudo and turned him into Edogawa Conan. She's also the victim of that medicine, too. She used to work in the Black Organization with her codename "Sherry"; but after the death of her sister Akemi, she ran away from them and currently lives with Agasa - The Old Professor. Haibara's also among the very few people who know Edogawa Conan's true identity.
Ai Haibara possesses a cool and calm personality, high intelligence, and sarcastic wit. During her first months after escaping from her organization, Haibra was cynical, always pushing others away. But later, she started to lose her coldness, embracing her new life while establishing stronger relationships with Conan, Ran, and Agasa.
Ai Habara is also pretty quiet - a girl of few words - though that might be a tactic to hide away from the Organization's members. She considers the Detective Boys (Conan, Ayumi, Genta, and Mitsuhiko) as the first friends she had, willing to do everything to keep them safe, even if that costs her own life. Hence, Haibara sometimes views herself as a dangerous threat to her friends, since she's certain the Organization will kill them all once they find her.
