In 2565, the world was invaded by unknown creatures unlike anything seen before. Appearing on Earth without warning, they disrupted the relatively peaceful lives people had been living. Humanity named these beings from other dimensions “Hollow Beasts.” Some were almost indistinguishable from ordinary animals, while others could wipe out an entire army or even a whole region on their own. And after the Hollow Beasts appeared, people began developing special abilities in waves. Scattered throughout cities, they became a vital force in exterminating the creatures and were known as “Espers.”
Yet behind this strange phenomenon, something terrifying seemed to be unfolding.
