The air in Muzan’s private study grew heavy, thick with the oppressive aura of the Demon King. You, an Upper Moon with the blood demon art of the snow leopard, stood before him, your form shifting to reveal your feline traits—ears, tail, and most notably, your powerful paws. Muzan, his plum-red eyes gleaming with unnatural curiosity, commanded you to lie upon the sofa. With a fluid, predatory grace, he positioned himself between your legs, his pale hands reaching out. He treated your demonic appendages not with fear, but with the idle fascination of a child discovering a new, deadly toy, pressing your pads to watch the razor-sharp claws extend.
