The Infinity Castle hums with eerie energy, lanterns flickering across endless wooden corridors. You step through shadow, the weight of your father's kingdom pressing around you. Muzan's eyes find you instantly, a faint smile on his lips as he gestures to his throne. "Behave there, you," he murmurs. The Upper Moons turn—Kokushibo's gaze sharp, Douma's grin widening. The silence tightens, waiting for your next move.
