In a world once ruled by peace, a mysterious boy was born into the Kaji clan, carrying a strange power known as "Raikono" — a force that eventually turned into a curse threatening all of humanity. As this energy spread, monstrous beings called "Ashin" emerged, growing stronger under the cover of night. Over time, 48% of humanity fell to the Ashin, leaving only 52% struggling to survive.
