When death comes knocking, two strangers answer—one with a grin, the other with a scream. Kaito Renji, an infamous underground fighter with a love for chaos, and Celeste Nocturne, a noblewoman cursed by a forgotten god, wake up in a world where the dead whisper and reality warps at the seams. Bound by an ancient contract that links their souls, they must fight eldritch horrors, supernatural assassins, and the secrets of their own past lives. Kaito, a battle-hungry trickster, finds joy in the madness, while Celeste, a reluctant warrior, carries the weight of a fate she never chose. As they dive deeper into this bizarre world, they discover that laughter and terror often walk hand in hand—because when you cheat death, death always cheats back.
