EDOGAWA CONAN

At the beginning of the series, Shinichi brings his friend Ran Mouri to Tropical Land, a local theme park, to celebrate her victory in the Metropolitan Karate Championships. He later ends up solving a murder case there.[5] As they are leaving, Shinichi witnesses a suspicious exchange between an unknown businessman and a man in black in a secluded area by the Ferris wheel. While spying on the suspicious men, Shinichi does not notice another man in black, who knocks him out from behind and forces him to swallow a new experimental poison known as APTX 4869. They then leave him to die. However, instead of killing Shinichi, a rare side-effect occurred. Shinichi's body shrunk back to that of his six-year-old self.[6] In desperation and confusion, Shinichi heads back to his house and runs into his next-door neighbor and close family friend, Professor Agasa. After a few attempts at proving he's Shinichi, he finally succeeds in convincing the Professor. The latter warns him he must keep his identity secret as the Black Organization will surely try to kill him and others associated with him should they learn the truth.[7]
