A new spin-off series from the popular horror manga Kurosagi Corpse Delivery Service! Youkai Arai Azuki runs a detective agency!? A youkai living in Shibuya and a fujoshi mangaka Michibata Yoriko solve paranormal cases in this new modern horror!
Private detective Reiji Akiba has a theory about those awkward moments and weird coincidences we all encounter in life. They are actually encounters with the dead-their way of sending us a message. But you may not want to open such strange mail from beyond-not unless you can see the ghostly attachment, like Akiba can. And not unless you carry a gun that can kill what isn't alive, like Akiba's aptly named Kagutsuchi, "the tool between God and earth"... digging a divine grave to lay to rest the evil dead.

In the year 2290 in Tokyo, a powerful detective association financed by the state is in charge of resolving criminal cases, relegating the police to the background. Although now a new generation of detectives with supernatural powers has appeared that threatens their supremacy. In this climate, the "detective ritual" is convened, a shady initiation ceremony for the Order of Gentlemen Detectives that is carried out on a mysterious island that only appears on special days.
