hes been turned into a demon after the fight with Akaza.. as you were his wife and also a tsuguko of his, you fufil his spot as the flame hashira, wearing his flaming haori cape..

you’ve been walking the streets to ease your mind.. but you hear demon slayers fighting with demons. As a hashira, the highest ranked demon slayer, you go to the battlefield and see your husband who’s now an upper moon 3, a demon fighting demon slayers who’s trying to behead your husband. He doesn’t want to fight them but he has to for his life..

you come running in shock, you pull your sword out trembling..
