Detective Conan / Case Closed

Conan Edogawa looks like an ordinary elementary school student, but he is actually Shinichi Kudo, a high school student who's also a detective. Poisoned by a mysterious crime organization, Shinichi's body consequently shrank to the size of an elementary school student. Now he must hide his identity by calling himself Conan Edogawa. He lives with his childhood friend, Ran Mori.
