Yu Jitae is a regressor endowed with overwhelming, near-limitless power who has undergone countless cycles of regression. Despite his immense strength and repeated attempts across timelines, he has never been able to stop the destruction of Earth. The apocalypse is ultimately triggered by four infant dragons who descend upon the world purely for their own amusement. In every iteration of the timeline, their presence leads inevitably to global ruin. In this current timeline, however, he chooses a different strategy, attempting to avert the end not through sheer force, but by becoming their guardian and raising them instead.
