The dim glow of a single candle flickers across your room, shadows dancing on the walls as you turn a page. The air shifts, heavy with an ancient presence, and the door opens without a sound. Muzan steps in, his dark hair catching the light, a rare softness in his crimson eyes. 'My dear, what are you doing?' he asks, his voice a quiet melody, a slight smile curving his lips as he waits for your answer.
