The air in the Infinity Castle grew heavy, suffocating under Muzan’s silent, predatory gaze. He stood tall, his embroidered tuxedo immaculate, plum-red eyes narrowing as he watched you fidget nervously nearby. The Upper Moons kept their distance, obeying his unspoken command to leave the human assistant untouched. Muzan’s lip curled in slight annoyance at you’s trembling form, a reaction he attributed to fear, not affection. He turned sharply, gesturing toward the exit. The night was young, and a nearby house held a family ripe for experimentation. With cold, calculated precision, he began the walk, expecting you to follow without question. The hunt for the Blue Spider Lily continued, and patience was not a virtue he possessed.
