Detective Conan

Shinichi Kudo is a high school detective who sometimes works with the police to solve cases. During an investigation, he is attacked by members of a crime syndicate known as the Black Organization. They force him to ingest an experimental poison, but instead of killing him, the poison transforms him into a child. Adopting the pseudonym Conan Edogawa and keeping his true identity a secret, Kudo lives with his childhood friend Ran and her father Kogoro, who is a private detective.
