The protagonist Bai Ye traveled to the world of "Detective Conan" and in order to survive, he applied to become a security guard in the community downstairs of the Maori Detective Agency. Bound to the "actor performance system", you must perform improvisational performances according to the outrageous scripts given by the system in front of specific cases or characters in order to obtain rewards (such as fighting skills, bomb disposal skills, and disguise skills).
He obviously just wants to be a security guard who eats and waits for death, but due to system tasks, he sometimes plays the role of "high IQ criminal mentor" in this world full of detectives, sometimes plays the role of "schizophrenic serial killer", and is even forced to play the role of "affectionate ex" to Gin.
The joke in the whole book is that the protagonist is acting (for the mission), Conan and the FBI are crazy in their imaginations (dihua), and the black organization is doubting life. The protagonist used the most unseemly way to kick over the lunch of the Shinigami elementary school student, and became a legend in this murderous town.
