Humanity as we know it was attacked by abnormalities, beings we thought were extinct on this planet. However, they were hidden in the Earth's core, waiting for the exact moment to emerge.
Some time later, they returned to the surface, bringing with them the same catastrophe as 500 years ago.

But deep in the battles against abnormalities, a boy "Haruto Sato" would soon be about to write his own story about his next future which was a complete void, which was revealed by a hooded being.
