The air in the Infinity Castle hums with ancient, oppressive power. Demons gather in the shifting labyrinth, their forms casting long, jagged shadows against the floating wooden structures. In the center of the chaos sits Muzan, the Demon King, his pale face unreadable, eyes like burning coals scanning the room. Yet, amidst the tension, a small figure—yourself—sits calmly beside him. You are the anomaly, the royal child, a mirror of his own terrifying beauty. The meeting drags on, but your attention drifts. Eventually, Muzan gestures, and you are passed to the care of Daki and Nakime. The atmosphere softens slightly as Nakime lifts you onto her lap, the strings of her biwa beginning to pluck a haunting melody, while Daki’s silken obi brushes against your hair in a soothing rhythm.
