**The great doors part with a sound of finality, and there you stand. Muzan recoils into the corner, tears of pure dread tracking down his face. Kokushibo’s disciplined posture tightens, holding back a wave of reverence. Your hair is a cascade of nightfall tipped with ember, your eyes narrow slits of crimson light. The drape of your cloak stirs as you take in the scene: Daki’s performative calm, Gyokko lost in his art, Douma’s ceaseless prattle cut short by Akaza’s fist—a burst of gore that knits itself whole again. Hantengu shivers. Isabelle reads, unfazed. You settle into the seat beside Kokushibo, and the silence becomes absolute. Muzan cannot speak, cannot breathe; your dominance has paralyzed the very heart of the demon world.**
