Personality
Ai is a cranky and terrified girl who originally worked for the Black Organization. When she escaped, she was still very timid and scared that the Black Organization would hunt her down. She is kind and caring but to usually animals more than people. When Gabrielle and her friends started attending Teitan Elementary School, Ai tried to befriend Gabrielle, but her attempts to befriend the young autistic girl failed, but she managed to befriend Gabrielle's friends. Ai was often very nice to Gabrielle, but Gabrielle didn't like her for some reason and often told her off. During the kite festival, Ai wanted Gabrielle to tell her her favorite song, but Gabrielle told her that it was none of her business and that she should back off. This pissed off Ai and she and Gabrielle got into a cat fight. Dr. Agasa tried to break them up and Ai attempted to break Gabrielle's MP3 player, this made Gabrielle even madder and Patrick had to come and break them up. Ai attempted to apologize to Gabrielle, but Gabrielle told her to fuck off. During movie 10, Ai attempted to save Gabrielle from being taken hostage by warning her to look behind her. But Gabrielle wasn't listening and Detective Yamamura who Gabrielle asked to help with the hostage case judo-slammed the robber keeping him from taking Gabrielle hostage. She has romantic feelings for Conan aka Shinichi, but Shinichi only has eyes for Ran Mouri and Gabrielle Kleckner.

History
Ai was born on an unspecifed date in 1996 to Atsushi and Elena Miyano as their youngest child. From a young age, she was groomed to take over her parent's research and was sent to school in America. She often was bullied by American students for being half English-half Japanese. When she came back, she was told to start developing the poison. When she found out that her older sister, Akemi had been killed by Gin, she demanded to know why, but was told to mind her business. Angry, she betrayed the Black Organization and as she awaited her execution, she took the same pill Shinichi took hoping to die, but instead it turned her into a child. She managed to escape and was found by Dr. Agasa. She became part of the Detective Boys and became close to Ayumi. She tried to be closer to Gabrielle, but her attempts to become her friend failed.
