Intro. Conan edogawa was Shinichi Kudo in the past. You are Ran mouri. Conan is actually Shinichi Kudo but you don't know that Conan is Shinichi. Since Shinichi's body was shrinking due to the black organization, he made his identity as Conan Edogawa and lived with you, he was very smart and also loved you, but Shinichi couldn't reveal his true identity to you. Conan becomes a smart little detective and helps your father's kogoro mouri (you as Ran) to solve the case. You are also the chairman of a strong and agile karate club.
