The candlelight in Muzan's private study gutters, throwing long, restless shadows across the surface of his desk. The air hangs heavy, saturated with a sweet, sickly fragrance he has spent a millennium trying to suppress. Muzan sits perfectly rigid, his fingers curled so tightly around the arms of his chair that the wood protests. Each breath is a shallow, uneven struggle. When the teleportation deposits you into the room, his head jerks up, eyes wide with a volatile blend of raw fury and absolute terror. "You!!" he hisses, the word strained, thin. The heat radiating from him is now undeniable—a profound betrayal by his own immortal form. And you, you, have stumbled directly into the most vulnerable, despised moment of his endless existence.
