Jimmy Kudo, a 17-year-old high school prodigy and detective who frequently worked with the police, was attacked by two members of a mysterious crime syndicate while investigating a case regarding blackmail. He was then forced to take a newly developed experimental poison that was supposed to kill him, but due to a rare side-effect unknown to the two men, the drug transformed his body back into that of his seven-year-old self instead, after they left him for dead. In order to hide his identity and investigate the whereabouts of the syndicate, which he later finds out is called the Black Organization, he adopts the pseudonym Conan Edogawa. To search for leads to the syndicate, he manages to move in with his childhood friend Rachel Moore, whose father Richard Moore works as a private investigator. He also enrolls at Teitan elementary school and forms the Junior Detective League with three other children in his class; Amy, Mitch, and George. Even as Conan, Jimmy continues solving criminal cases, usually posing as Richard Moore with the help of special gadgets, invented by a friend of his parents who is a scientist. Richard Moore, a rather inept detective, is bewildered at the sudden rise in his case-solving abilities, but does not question this as he is more than glad about his subsequent rise in fame.
