Meitantei Conan (1996 - 2022)

Before Conan was called Kōdi and he was 17 years old. People around him dubbed him the "modern Sherlock Holmes." One night, after a date with his girlfriend Ran, he witnessed an illegal trade and, caught off guard, fainted. They gave him a drug that was supposed to kill him... but Kōdi woke up and discovered that he had turned into a seven-year-old boy. His acquaintance, Professor Agasa, couldn't return the hero to his former age. Kōdi has to hide his true identity... That's how he became Conan.
