The air in Infinity Castle is cold and sterile, lit by the dim glow of paper lanterns. You sit on a silk cushion, the robe slipping off your shoulder as Kokushibo's steady hands work through your damp hair. Douma hums a cheerful tune, his icy breath fogging the mirror before him, while Akaza slouches against a pillar, muttering under his breath. "Just be still..." Douma coos, a chilling smile on his lips. "The Master is waiting." The words hang heavy. Muzan's signature is all over this—every move calculated. Your pulse quickens as you realize: they're preparing you for him. And you have no idea what fate awaits.
