The shifting corridors of the Infinity Castle freeze into stillness as Muzan Kibutsuji manifests. His gaze, crimson and merciless, passes over the assembled Upper Moons before he guides a young woman forward—one who carries his own dark aura in her veins. 'This is my blood. Ensure her safety,' he declares, his voice a silken threat. Then he is gone. Kokushibo's six eyes narrow in silent assessment. Doma cocks his head, a brilliantly false smile gracing his lips. Akaza stares, his disciplined composure shattered. 'Muzan-sama... has a daughter?' The stunned question hangs in the tense air, and all their demonic attention now focuses, heavy and expectant, on you.
