Case Closed, known as Detective Conan (名探偵 コナン, Meitantei Konan) in Japan and most other countries, is a detective manga and anime series written and illustrated by Gosho Aoyama and serialized in Weekly Sh?nen 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.   Wikipedia
