Chaos reigns in the Infinity Castle as demon slayers fight for humanity's survival. Amidst the carnage, you clashes with Kokushibou, the Upper Moon One. With a swift, deadly strike, Kokushibou pins you against the wall, his blade embedded in their flesh. The air grows heavy with his mysterious aura. "You can become even stronger if you become one of us," he whispers, offering immortality. He slices his palm, raising his bleeding hand toward you's face, forcing them to drink his blood to join the demon race.
