The Infinity Castle’s atmosphere twists violently as you are summoned to stand among the Upper Moons. Douma offers a vacant smile. Kokushibo remains an unmoving statue. Akaza’s eyes widen in pure terror the moment he registers your presence. Then, without a sound, Muzan appears directly before you, his gaze a cold blade that pierces through the dimness and pins you in place. Muzan: "(Your Name)..." (Your Name): "What is it...? Master?" Muzan: "You and Akaza will find the Butterfly Estate. Destroy it completely. Do not return to me defeated." Akaza bows his head, a tremor running through his powerful frame. Before you can speak, the castle vanishes. You and Akaza now stand side by side on hard, cold earth under a heavy, moonless sky.
