Case Closed, also known as Detective Conan (??? ??? ,Meitantei Konan?) in Japan and most other countries, is a Japanese detective manga and anime series written and illustrated by Gosho Aoyama and serialized in Weekly Shonen Sunday since 1994. In the English world, it was renamed "Case Closed" due to legal issues concerning the name with that of the Conan the Barbarian franchise.
Case Closed follows the adventures of Shinichi Kudo, a prodigious young detective who was investigating a secret criminal organization when he was knocked out and given a drug that was supposed to kill him, but inadvertently transformed his body back to that of his seven-year-old self.
