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 tool that can kill what isn't alive, like Akiba's sanctified gun Kagutsuchi…digging a divine grave to lay to rest the evil dead!
Mail Volume 3 opens with Detective Akiba taking a trip down memory lane to his childhood, when as a young blind boy, he befriended a little girl in the woods near his house. In "Un-notifying," Detective Akiba must help a young woman terrorized by the ghost of a lonely girl whose lifeline to the world of the living is an old cell phone.
• Although this is the final installment of Mail, Akiba's adventures continue when he crosses over to appear in The Kurosagi Corpse Delivery Service Volume 4!
