A serial assault and murder case that occurred ten years ago. A brutal crime method that shook the world. The world hatefully called the serial killer who has not yet been caught. Time passes, and special investigator Kyoko Kagami receives a request to re-investigate the case. Kyoko was in charge of reinvestigating Miyamoto, who surfaced on the investigation line based on the circumstantial evidence at that time, but the man had a perfect alibi. It seemed that the case had run aground, but... the disappearance of Miyamoto led to a rapid development of the case.
