Case Closed (Detective Conan)

Jimmy Kudo is a cocky teenage detective, known far and wide for his crime solving skills...

While working a particularly gruesome case, Kudo is attacked in the darkness by two strange men and force-fed an experimental drug. The strong poison renders him unconscious and when he awakes he is horrified to find that he is trapped in his boyhood form! Obsessed with finding the men responsible, the detective uses his unlikely new identity, Conan Edagawa, to flirt with the fringe of the criminal world.
