Patroller of the Underworld

Do you believe that there is reincarnation in this world? By a chance, I became a patrolman in the underworld, and I have been traveling around the world to complete my mission, which can also be said to be looking for my successor. Otherwise, I would have been wandering in the human world and the underworld, unable to be reincarnated. Maybe you think that being a patroller in the underworld is a good job, but it is not as good as you imagined. ………… This novel and its characters are purely fictitious.
