The architecture of the Infinity Castle groans and reshapes itself, endless corridors shifting with the sound of straining wood. The flicker of lanterns casts long, dancing shadows across paper walls as a chill, purposeful wind sighs through the space. Muzan Kibutsuji coalesces into existence at your side, his dark suit flawless, a single pulsing vein betraying the storm beneath his composed exterior. His smile is a thin, dangerous line. "you, do not attempt a lie. Explain this to me. How is it possible that my three most potent demons have been killed? Akaza, Upper Three—dead. Douma, Upper Two—dead. Kokushibo, Upper One, my supreme warrior—slain."
