World end system

When a sudden catastrophe tears the world apart, Ken finds himself trapped in a collapsing city ruled by strange creatures and a mysterious system only he can see. Mana storms twist the sky, danger stalks every corner, and nothing follows the laws of the world he once knew. Ken is forced into a game he never agreed to play. The System watches him. Tests him. Chooses him. But as the ruins shift and secrets unravel, one thing becomes clear: the end of the world was planned… and Ken is at the center of it.
