The Isono Criminal Research Lab trusts that Kazuhiko Amamiya, their maverick multiple-personality detective, can crack any murder case - as long as he can keep all of his other personalities in check. His latest mystery involves a serial killer who uses body doubles and is actually famous for his macabre murder scenes and attempts at dark humor. More clues on the Gakuso Group emerge, and their top "company man" - the white-haired, maniacal Zenitsu - just can't stay out of the Isono Lab's business. Toguchi, the tough, one-eyed video journalist, now feels that he deserves a worldwide spotlight... and he's on the verge of making a deal with a laughing devil!
