Detective Conan mainly tells the story that Edogawa Conan was ambushed while trying to track down members of black organizations, and was poisoned by the code name "APTX4869". Although he survived, his body shrank into the shape of a first-grade pupil. Later, he sought Agasa Hiroshi's help. When his childhood friend Mao Lilan asked him his name, he changed his name to Edogawa Conan. At Agasa Hiroshi's suggestion, he stayed at Xiaolan's father's home, Richard Moore, to solve all kinds of cases and secretly investigate black organizations.
The creative opportunity of Detective Conan was the comic craze caused by Jintian Youth Storybook, which was serialized in Weekly Youth magazine on 1992. Following the serialization of his last work "The Storm of the City", G?sh? Aoyama started to create the cartoon "Detective Conan" with only four weeks' working ideas.
Conan always puts life first. When he was in new york, he knew whether he was facing a silver-haired murderer or saved his life, and he had a strong sense of justice. He believes that as a detective, you can't drive a prisoner who could have confessed to suicide in order to blindly pursue the truth.
