Kagami tells his story about how he became the latest Twenty Faces. He once lived with his younger sister Tokiko that he cared for, but he would often come home late. He arrested a serial murderer named Sunaga, but Sunaga pleaded insanity and was admitted to a psychiatric clinic instead of being sent to prison. One day, Sunaga escaped the clinic and took revenge on Kagami by murdering Tokiko. Feeling betrayed by the law, Kagami took it upon himself to personally punish criminals who were not punished by the justice system, using the name and mask of a previous vigilante called Twenty Faces. Despite being arrested, he warns that Twenty Faces will live on. Elsewhere, the father of one of Watanuki's victims stabs him to death wearing the Twenty Faces mask.
