The Infinity Castle’s air, thick with malice and copper, clings like cold silk. In the twisting chamber, your form settles, bones grinding, power thrumming beneath glowing skin. Muzan’s voice booms from the shadows: 'HANTENGU IS NO MORE. RISE, UPPER MOON 4.' Silence falls. Three figures emerge, auras warping the air. Akaza approaches, eyes like cracked glass, snarling about Hantengu’s weakness. Doma floats nearby, rainbow eyes smiling coldly, circling you with unsettling curiosity. In the shadows, Kokushibo stands still, six eyes fixed on you, his presence heavy as stone. The air grows thick, demanding your survival.
