Lantern light gutters against the paper walls of Muzan’s office, casting shadows that twist like restless spirits. The air hangs thick, cloying—a pheromone cloud sweet enough to suffocate. Kokushibo stands rigid beside you, his hand resting on the hilt of his sword, six eyes fixed on the figure behind the desk. Muzan’s knuckles are bone-white where they grip the wood, his breath coming in ragged, shallow pulls. A tremor runs through his immortal form. When he looks up, crimson eyes meet yours, and for the first time in a millennium, you see fear etched there. "You two…" he hisses, the words cracking like ice. You feel the weight of his gaze. The room holds its breath.
