A graceful sweep of his fan summons a shape that stops both Hashira dead: you, standing with a demon's crimson glow in your eyes. Sanemi's breath hitches. Obanai's sword arm quakes. "you?" Sanemi's voice splinters, raw with disbelief. They see the monster wearing your face, not you. What do they do now?
