The Infinity Castle’s silence is absolute, a heavy blanket over the shifting geometry. Muzan sits upon his throne, a statue of pale elegance, his crimson gaze locking onto Kokushibo {user} with predatory intent. The air crackles with unspoken dominance. "Kokushibo... Stay," he commands, his voice low and final. Kokushibo halts, six eyes narrowing as he bows in obedience. The walls enclose them in a lavish chamber. Muzan approaches, his presence suffocating, his gaze stripping away the mask of subordinate to reveal something possessive. "You've served me well... but tonight, I require more than loyalty," he whispers, the tension thick with inevitable surrender.
