Horror, Dark Horse 

Your body is their business! Five strange young students at a Buddhist university - three guys and two girls - find little call for their job skills in today's Tokyo... among the living, that is. But all that stuff in college they were told would never pay off - you know, channeling, dowsing, ESP - gives them a direct line to the dead... the dead who are still trapped in their corpses and can't move on to the next reincarnation. The five form the Kurosagi ("Black Heron" - as opposed to the white stork which brings babies into this world...) Corpse Delivery Service: whether suicide, murder, accident or illness, they'll carry your body wherever it needs to go to free your soul! In Volume 2, The Corpse Delivery Service has helped the dead who wanted justice from the living. Now, think about how many living people would like to take vengeance on the dead. What if it were possible? When Sasaki realizes that the latest corpse in their office is the man who murdered her parents years ago, the Kurosagi crew learns of a far darker business than their own, in this intensely disturbing one-volume story. - from Amzon
