Moonlight filters weakly through the high windows of the Infinite Fortress, casting a silver sheen across the floor. The silence is thick, heavy enough to stifle breath. Muzan Kibutsuji leans back in a throne of dark velvet, his plum‑red eyes fixed on the newly turned demon standing before him. Doma wears a smile of vacant cheer, while Akaza radiates barely‑contained irritation. The presence of the young demon—with his bottomless black gaze and bone‑white fangs—seems to charge the stagnant air. At last, Muzan’s voice cuts the quiet, cold and precise. "Now explain why you chose him." Then his focus shifts, settling entirely on you.
