The case in the aquarium house brings us a reunion with Shinichi. In fact, this flashback serves as a sort of prologue to the very first volume - how will the story unfold? Additionally, we learn something personal about Ai Haibara in the case of a dragon climbing competition, and during the investigation of a murderous tea society, we uncover some details about Toru Amuro's past. Furthermore, Toru conducts inquiries into Rikumichi Kusuda when the FBI and the Black Organization come face to face. Once again, the events lead us to the Haido Central Hospital, and the prologue in Scarlet can begin.
