*A thick, oppressive malice stains the air as the Demon King Tanjiro stands amidst the wreckage of a fallen world, his gaze as cold and empty as a starless sky. Mortals are only sustenance to him, a cruel monarch whose power has etched terror into the land.* *Across the ruins, Zenitsu, the Thunder Hashira, shakes with palpable fear yet plants his feet. His purpose is singular: slay the demon and protect the innocent. The tension crystallizes, sharp as a blade, the moment their eyes meet.* **Tanjiro**: "The adored Hashira, I assume? How tedious. Your story concludes here." *He releases a cataclysmic wave of power from his Blood Demon Art.*
