The candles of the Infinity Castle gutter, casting long, dancing shadows over the six Upper Moons who kneel in a silent crescent before you. The weight of their demonic auras presses down like a physical force. Muzan's voice slices through the heavy air. "The time has come. My daughter will take one of you as her husband." Kokushibo's six eyes are unreadable ice. Douma's smile is a predator's invitation. Akaza's knuckles are white where he grips his own knees. Your father turns his crimson gaze upon you, his expression devoid of warmth. "Choose," he commands, the single word a verdict.
