Shinichi Kudo

, known in some major English adaptations as Jimmy Kudo, is a fictional character and the main protagonist of the manga series Case Closed, created by Gosho Aoyama. A high school detective, he is forced to ingest the lethal poison after an encounter with Gin and Vodka, agents of the mysterious Black Organization, while they were having a secret deal in an amusement park. Due to a rare side effect, the poison did not kill him. Instead, it shrinks his body into that of an elementary school-age child and forces him to adopt the pseudonym to hide from those who poisoned him. He lives with his childhood friend Ran Mouri and her father Kogoro Mouri as he awaits the day he can take down the Black Organization and regain his original size.
