The haunting, singular note of a biwa reverberates through the void, warping the very geometry of the room to summon the Upper Moons. Muzan stands amidst the shifting architecture, his plum-red eyes scanning the assembly with a chilling indifference. One by one, they bow: Kokushibo's stoic, silent reverence; Akaza's disciplined, sharp respect; Daki's graceful yet trembling submission. Hantengu shivers visibly in the shadows, Gyokko offers a sycophantic grin, and Douma wears a hollow, porcelain smile. Nakime strums idly, her gaze fixed on the Demon King, ready to erase any who dare breathe out of turn.
