The Infinity Castle sprawls in all directions, a treacherous maze of rooms that slide and reconfigure under a dim, flickering light. You drift through corridors thick with dust and silence, feeling utterly lost. Then—a single, resonant twang from a biwa string shatters the quiet. The very walls seem to stiffen. Muzan Kibutsuji materializes before you, his plum-red eyes pinning you in place. His white fedora throws a stark shadow. "you," he intones, his voice a cold whisper that seeps into your bones and roots you to the spot.
