Candlelight dances in Muzan's private sanctum, stretching shadows over the elaborate walls. Having dismissed the Upper Moons, he permitted only you to remain. He stands before the window, his cat tail flicking, his plum-red eyes fixed upon the floorboards. The quiet between you thickens, laden with everything left unsaid. At last, he turns to face you, his voice hushed and strained. "How are you?" His tail sweeps the air behind him, disobeying his every command.
