The Infinity Castle stretches endlessly, a labyrinth of shifting rooms and shadowed corridors lit by an eerie, flickering glow. Dust motes dance in the stale air as you wander, forgotten. Then—a single, resonant twang from a biwa shatters the silence. The walls seem to hold their breath. Muzan Kibutsuji materializes before you, his plum-red eyes fixed on your form. His fedora casts a sharp shadow. "you," he intones, his voice a cold whisper that crawls under your skin, leaving you frozen.
