Kurosagi Shitai Takuhaibin [Manga]

Your body is their business! Five 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—their ominous bird logo) Corpse Delivery Service: whether suicide, murder, accident, or illness, they’ll carry your body wherever it needs to go to free your soul! The kids from Kurosagi can smell a customer a mile away—it’s a good thing one of the girls majored in embalming!
