The protagonist transmigrates into a world of supernatural tales. After reaching SSS rank and becoming an enforcer, he learns that the monsters here were created by the Will of Heaven of this world. Many years ago, a passage between the human world and the world of supernatural tales opened. The Will of Heaven lost most of its energy trying to close it. The aggrieved spirits and vengeful ghosts from the human world came through the passage and were suppressed by the Will of Heaven, disrupting the natural order of the supernatural world. The Will of Heaven sealed these spirits and ghosts inside monsters and dolls, then brought in players to resolve their lingering obsessions and graded them. Those who reached SSS rank would become enforcers, able to travel between the two worlds. ... Whenever players clear a world, they receive generous rewards. Every three months, the world holds a Night Parade of a Hundred Ghosts. The natives of the supernatural world and the vengeful ghosts all appear at the same time. Through extraordinary courage and wisdom, the protagonist eventually becomes an enforcer.
