Ai Haibara (灰原 哀 ,Haibara Ai?), real name Shiho Miyano (宮野 志保 ,Miyano Shiho), is the inventor of the APTX 4869 poison that shrunk Shinichi Kudo into Conan Edogawa, and a victim of the poison herself. Formerly Sherry (シェリー) of the Black Organization, she is on the run from them and lives with Professor Agasa. She is also one of few characters who knows Shinichi is Conan.


Shiho Miyano and her older sister, Akemi Miyano aka Masami Hirota were born into the secret crime syndicate "The Black Organization". Of course, while Akemi lived a normal life, Ai was sent to America as a small child to go to school and was groomed to finish her parents' research. She was born to an English mother, Elena Miyano, and a Japanese father, Atsushi Miyano. Both of whom were members of the organization, and deceased. A prodigy, she was sent to the United States for education at a very young age, then later came back to Japan to finish her parents' secret project for the organization. Her codename in the Organization is "Sherry", after the alcoholic drink.

Shiho was about 18 years old when she developed the experimental test compound APTX 4869. She discovered that it could be used as a poison to kill without leaving any traces of itself in a body. While researching its effects, Shiho noticed that a rare few of her lab mice had become younger after being given the drug instead of dying.

Meanwhile, the Black Organization started using APTX 4869 to commit untraceable murders. Unaware of the drug's rare side effect when they used it on Shinichi Kudo, the Organization ordered a search for him because his body had not been found. Shiho searched Shinichi's house twice after he had been shrunk to confirm his death for the Black Organization. She began to suspect Shinichi's transformation after she searched his house for a second time and found that his clothes from primary school were missing. Shiho then confirmed him as deceased so the organization would not look into the matter further and kill him after all.

Her unhappiness over the Black Organization's usage of the APTX 4869 (for killing purposes), in addition to her open questioning over the murder of her sister, Akemi Miyano, resulted in her imprisonment and scheduled execution by the Black Organization. With no other way out, she took a pill of APTX 4869 to commit suicide.

Like Shinichi, she is one of the only two known rare cases who didn't die after taking the drug; but instead shrunk into a seven or eight year old girl. In her new smaller body, she escaped from the Black Organization and attempted to reach Shinichi's house, hoping he may be able to help her. Exhausted, she collapsed in front of Professor Agasa's house, who then found and adopted her.

Ai HaibaraEdit

To prevent the knowledge of her transfiguration from being discovered, she and Hiroshi Agasa created her alias Ai Haibara (known as Anita Hailey - recently Vi Graythorn - in the English dub). As Ai Haibara, she attends Teitan Elementary School with Shinichi Kudo's shrunken form, Conan Edogawa. Following her first adventure with the Detective Boys in which they investigated the disappearance of a schoolmate's brother, she revealed her true identity to Conan and the fact that she had developed the APTX 4869.At first stunned, then outraged, Conan protested her presence, but as time went by, he accepted Ai as a friend and fellow victim, though her cynicism and secretive air still rail him at times.

Eventually, Ai joined the ranks of the Detective Boys, and although she does not think too highly of her mates' immature antics, she has come to value them all as close friends.
