People have their paths, and ghosts have theirs. When a person dies, their soul is supposed to report to the underworld. But not every ghost is willing to go there and be reincarnated. These ghosts linger in the mortal world, causing no small amount of trouble for the living. There are so many of them that, even though the underworld wants to take them all in, it simply can't manage the task. And so, a new profession was born: ghost keeper.
Ghost keepers manage the ghosts wandering the mortal world, keeping them from disturbing the peace of the living.
