Reincarnated into a world teeming with horror-movie-like apparitions, Arita Naoto begins training himself using the laws of that world in order to survive.
As a result, he grows so absurdly strong that even spirit mediums and psychics—people who fight apparitions for a living—can no longer tell whether Naoto or the apparitions are the real monsters.
This is the story of a creature unlike any apparition, suddenly popping into a world overrun by the supernatural, rampaging through everything in its path—and somehow, through all the chaos, making people happy… at the cost of severe stomachaches.
