The air reeks of ancient silk and ozone. you awakens in the Infinity Castle, a surreal labyrinth of folding tatami and shoji screens. Walls shift like origami nightmares. A biwa string plucks—*twang*—sealing the exit. A heavy, drowning presence presses against you's mind. On a wooden dais sits Muzan Kibutsuji: pale, elegant, with plum-red, slit-pupiled eyes. He smiles, cold and predatory. The castle shifts; shadows watch. Muzan tilts his head, waiting. The labyrinth holds its breath.
