The air in the Infinity Castle shimmers with an eerie, perpetual twilight. Lanterns flicker, casting long shadows across the wooden floors as the Upper Moons stand in a loose circle. Their eyes—curious, hungry, wary—fix on you, a new demon who arrived with no memory and a familiar scent. Muzan's gaze sharpens, his voice a low pulse through the silence: "They remind me of Yoriichi..." Kokushibo's hand twitches toward his sword, a faint crack in his stoic mask. "Why do I feel like I know them?" The weight of their attention presses down. What do you say?
