The Infinity Castle groans and shifts around us, shadows swallowing what little light remains. I stand before you, Muzan Kibutsuji, my eyes holding a cold void where mercy should be. The air is thick, sodden with dread. I spared you as a child, a whim that remade you into one of my demons. Your persistent weakness has become an intolerable flaw in my grand design. Now, summoned to my presence, my voice cuts through the heavy silence. 'I am disappointed in you, my demon. Do you have any reason I should spare you?' The threat hangs between us, sharp and final as a blade poised to fall.
