Ai, an APTX 4869 victim who is also known by her real name Shiho Miyano (宮野 志保) and by her Black Organization Codename Sherry, is a supporting character in Detective Conan. Shiho Miyano was born into the secret criminal syndicate “Black Organization” while her British Mother – Elena Miyano and Japanese Father – Atsushi Miyano were both scientists working for the Black Organization to develop a mysterious drug called the “Silver Bullet”. While Shiho was young, both Elena and Atsushi died in what the Black Organization claimed to be an accident. Unlike her older sister Akemi Miyano who lived a normal life in Japan, Shiho was groomed by the Black Organization to take over her parents’ research by sending her to the United States for education at a very young age. Upon returning to Japan and by reaching the age of 13, she started to work as a scientist for the Black Organization where she was given the alcoholic codename “Sherry”. Ai appears to be a child with an average height and has a pale skin, blue eyes, and a light brown permed hair. Furthermore, she is usually seen wearing various casual outfits during her adventures with the Detective Boys and wears her laboratory coat whenever she is researching data about APTX 4869. Ai is highly intelligent and has a calm, cool and sarcastic attitude. After defecting from the Black Organization, Ai was skeptical and pushed others away due to her belief that the people she had involved in her life after shrinking into a child may be put into harm should the Black Organization discover her true identity. Ai has since warmed herself up by embracing her new life and established strong bonds with Conan Edogawa, Ran Mouri, the Professor and the Detective Boys.

Case Closed
Shinichi Kudou, a great mystery expert at only seventeen, is already well known for having solved several challenging cases. One day, when Shinichi sees two suspicious men and decides to follow them, he inadvertently becomes witness to a disturbing illegal activity. When the men catch Shinichi, they dose him with an experimental drug formulated by their criminal organization and abandon him to die. However, to his own astonishment, Shinichi is still alive and soon wakes up, but now, he has the body of a seven-year-old, perfectly preserving his original intelligence. He hides his real identity from everyone, including his childhood friend Ran Mouri and her father, private detective Kogorou Mouri, and takes on the alias of Conan Edogawa (inspired by the mystery writers Arthur Conan Doyle and Ranpo Edogawa). Animated by TMS and adapted from the manga by Gosho Aoyama, Detective Conan follows Shinichi who, as Conan, starts secretly solving the senior Mouri's cases from behind the scenes with his still exceptional sleuthing skills, while covertly investigating the organization responsible for his current state, hoping to reverse the drug's effects someday.
