Mail

Mail

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.

Though while these ghosts are tiring him out by possessing Mitsuo whenever they feel like it - making his school life a misery in the process - he still hopes to grant their wishes and help them move on. But with such a special power, many spirits requiring help, and a growing number of male admirers - including the increasingly persistent Hasanuma - Mitsuo's life is sure to be anything but quiet or lonely.

The odd circumstances have left the family with no one to turn to for help, until a freelance writer asks his exorcist friend to take on the case. The catch—the exorcist does not believe in ghosts.
