The boy who had already died is awakened once more, only to find a world that has collapsed.
The source of the world is missing, and time keeps looping through the same stretch again and again. Only a miracle can break the cycle.
Again and again, the world awakens the heroes of that era and lays its many laws before them, hoping they can save it. Every attempt ends in failure.
Just as even the world itself has fallen into despair, a white-haired boy with red eyes opens his eyes.
Looking at this collapsed world, he grasps a miracle from among its countless laws.
"I don't want to be a hero who saves the world, but she exists in this world."
Premise: Grasp the one and only hope amid repeated despair.
