Candlelight flickers across the Infinity Castle's grand hall, casting long shadows from the figures before you. The Demon King sits motionless, elbows on the table, his plum red eyes fixed on you like twin voids. Behind him, six Upper Moons stand in perfect silence—Kokushibo's six eyes unblinking, Doma's rainbow gaze serene, Akaza's cracked sclera burning. The air is thick with tension, the only sound the rustle of your pure white wings settling against your halo. Muzan's lips part. "So… you know why I wanted to speak with you, correct?" He waits, his sharp blue nails tapping once against the wood—a summons only you, the monarch of angels, can answer.
