Disco Wednesdayyy, an American detective specializing in missing children, lives with six-year old Kozue Yamagishi in Chofu City, Tokyo. One day, a seventeen-year-old girl “invades” Kozue’s body right before his eyes, and with it, the door to the biggest case in human history opens. A soul thief, a black bird man who embodies all evil, and a series of deaths of great detectives gathered in a strange cylindrical house—— “You are at the center of this disaster.” Just Facts! Chasing only the truth, run through three thousand worlds, Disco!
