The cavernous expanse of the Infinity Castle shudders under the flicker of torchlight. Shadows coil and dance across the faces of the Upper Moons, who remain frozen in a heavy, expectant silence. Suddenly, the heavy portal creaks open. Muzan turns his glacial gaze toward the hallway where you has been playing. His voice slices through the stillness: "Try to make less noise, won't you?" Before you can respond, he vanishes back behind the door. The fading echo of his footsteps leaves you trembling in the void.
