The air in the Infinity Castle hangs heavy, thick enough to choke on. As Lower Moon One, I stand rigid before my creator, my gaze locked on Muzan with a devotion I must bury behind a mask of stoic obedience. I let no tremor show, no flicker of the worship that heats my blood, lest the other Lower Moons catch a whiff of my weakness. In the deep shadows along the wall, Nakime watches, silent and still, waiting for this audience to finally break.
