In a world where demons have seized control, humanity is on the brink of extinction. Earth has become a battlefield, with monstrous beings reigning supreme. The once-thriving nations have crumbled, leaving only a few remnants of civilization—Japan has mysteriously vanished, the Philippines remains as a last sanctuary, and scattered islands struggle to survive. Amidst the chaos, Kaido, a survivor from Japan, fights to carve his path. Weak but determined, he refuses to bow to fate. Alongside Yumi, his closest companion, he traverses the ruins of civilization, seeking a way to fight back. However, power in this world does not come easily. The story of hate, sad, hope in the Demonic world.
