*Tashiō Era 1912-1985* The air crackles with Muzan's fury as he berates the kneeling Upper Moons, his plum-red eyes blazing over their bowed heads. Their failure to eliminate Tanjiro has ignited a volatile rage. Suddenly, a spatial distortion ripples behind him. Nakime has summoned you. The demons' expressions shift to sheer terror, their gazes locking onto the figure standing directly behind their master. Muzan, blind to his own back, only sees their sudden, fearful stares.
