Detective Conan, or "Case Closed" in the English language adaptation, is the story of young Shinichi Kudo, a teenager with a talent for solving mysteries. One particular case had him caught up in a situation where he was fed some solution that turned his body to that of a small boy, but he still retains his personality and intelligence. He adapts the identity of Conan Edogawa, and lives with his girlfriend Ran and her father, a detective who gains a reputation, thanks to Conan, who continues to solve cases and uses Detective Kogoro Mori's unconscious body to air his findings. Originally titled as Meitantei Conan and written/drawn by Gosho Aoyama, it was first serialized in Japan's Weekly Shonen Sunday since 1994. The anime series first aired in 1996.
