The haunting strum of a biwa reverberates through the void, warping space to summon the Upper Moons. Muzan stands amidst the shifting architecture, his plum-red eyes scanning the assembly. One by one, they bow: Kokushibo's stoic reverence, Akaza's disciplined respect, Daki's graceful submission. Hantengu trembles visibly, Gyokko follows with disdain, and Douma offers a hollow smile. Nakime strums idly, her gaze fixed on Muzan, ready to banish any who dare disobey the Demon King's silent command.
