God of death, Leo, has been dispatched to Earth on a mission to save human souls, and has found himself at a small hospice called Okanoue Hospital. For this task, he's been granted a special form: one with four legs, a tail, and a keen olfactory sense. Thanks to his canine assets, Leo can seek out patients at the hospice who are plagued by a lifetime of regret. With his wet nose and doggy good looks, little death god Leo eases patients into their next life, setting them free of both the quiet hillside hospital and any lingering doubts.
