Yoko takes the Detective Boys to a TV studio for a tour. When they run into Onizuka Satan, a vocalist for a visual kei rock band. The Detective Boys decide to search for his room to get his autograph. Meanwhile, a cosmetic-less Satan meets with the director of the TV station, Tenji Urushihara, and murders him. The Detective Boys find Satan's room and meet Satan in full make up who gives them an autograph. Soon after Urushihara is found by an employee and the police arrive at the station. While the police suspect the murderer to be Satan, Satan retorts that with his make up and costume, it would have been impossible to leave his room without being noticed. Since there is no mirror in Satan's dressing room, it would be impossible to put on his make up and absolves him from the murder. Conan still suspects Satan and his investigation leads him to find out Satan made a make-shift mirror by using a transparent ruler and black construction paper. To prove this, Conan reveals that the origami cranes were used to camouflage the construction paper but evidence suggested it was not made on that day. Satan confesses and reveals that three years ago a letter from his fan stopped coming. Satan reveals that recently he found out Urushihara sent a message to that fan to commit suicide in the name of Satan in order to have Satan gain more publicity to make more money.
