High school detective Shinichi Kudou is renowned for his sharp observational skills and brilliant deductive reasoning, helping the Japanese police solve cases that leave others baffled. One day, while out with his childhood friend Ran Mouri, Shinichi witnesses a suspicious transaction between two men. He is caught and forcibly given a poison intended to kill him, but instead of dying, Shinichi’s body is mysteriously shrunk to the size of a seven-year-old.

To protect his identity, Shinichi adopts the alias Conan Edogawa—drawing inspiration from famous mystery authors Arthur Conan Doyle and Ranpo Edogawa. Now living with Ran and her private detective father, Conan continues to solve challenging murder cases while secretly working to expose the mysterious organization responsible for his transformation, all in the hope of regaining his original body.
