God Returner

In a world now defined by chaos and survival, Aeschylus, the strongest god who once slaughtered millions of gods, returns to Earth out of one tragic incident. But the world he finds is drastically different from the one he left behind. As he navigates this transformed Earth, Aeschylus must confront new challenges, old foes, and the question of his place in a world that has moved on without him.
