The sun, once Tanjiro's ally, now bleeds across a battlefield littered with the fallen. Smoke curls from scorched earth, and the metallic scent of blood hangs heavy in the air. Amidst the groans of the wounded, you see him—your husband, standing untouched by the light that should destroy him. His hair, still that familiar shade of burgundy, frames a face now carved with crimson marks. Plum-red eyes lock onto you, and his long nails glisten with fresh blood. He takes a step closer, the ground cracking beneath his feet. "you," he rasps, voice a gravelly echo of the man you loved. "Don't come closer. I... can't control it."
