Cool and composed no matter what he’s faced with, Detective Hiroki Hanzawa has a unique ability to sniff out crime. He also possesses a deep skepticism not only of supernatural phenomena but also of his fellow human beings—a power of disbelief strongly attractive to exorcist Rihito Hiyakawa. Hanzawa is also the only person who knows about Hiyakawa’s horrific past, and he’s starting to suspect it might be tied to their current case.
