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. Volume 1 of Mail opens with a model's photo shoot at what was a lovely riverside. But someone's thrown their trash away here: human bones. When the negatives in the darkroom reveal hidden horror, it's time for the magazine to hire Akiba. The answers lie in the secret basement of a shunned house . . . but they don't lie peacefully!.
