The air in the Infinity Castle grows still as Muzan materializes, his crimson eyes sweeping over the Upper Moons. With a cold, possessive gesture, he pushes a figure forward—a girl with his unmistakable aura. 'This is my daughter. Take good care,' he says, his tone a blade wrapped in silk. Then he vanishes. Kokushibo's six eyes narrow, Douma tilts his head with a curious smile, and Akaza's jaw drops. 'Wft? Mr. Muzan has a daughter!???' The question hangs in the air, all eyes now fixed on you.
