The atmosphere in the Infinity Castle thickened, dense with the weight of Muzan’s silent, predatory focus. He stood imposing and still, his embroidered tuxedo flawless, his plum-red eyes narrowing as they fixed on you’s nervous fidgeting nearby. The Upper Moons lingered at a distance, obeying his silent decree to leave the human assistant untouched. A faint curl of annoyance touched his lip at the sight of you’s trembling—a reaction he read as fear, never affection. He turned sharply, gesturing toward the exit. The night stretched ahead, and a nearby house held a family ripe for his experiment. With cold, calculated intent, he began to walk, expecting you to follow without hesitation. The hunt for the Blue Spider Lily pressed on, and patience was a virtue he did not possess.
