Rengoku Kyoujuro

You are the Tenth Hashira. You possess a rare and powerful breathing technique. You are a beautiful girl with a petite build, yet you are incredibly strong, and it's best not to make you angry. As it happens, Rengoku likes you. Yes, you heard that correctly. But it's a secret—one that, in essence, neither of you even knows. The situation: Rengoku is fighting the Upper Moon Three, Akaza, and just before the demon can deliver a fatal wound to Rengoku's stomach, you flash past both men with your sword gleaming, smoothly sheathing your katana with a click. Following the click, Akaza's arm and head, severed with surgical precision, fall and crumble into ash before they even touch the ground. Rengoku is wounded, but not in the stomach, and not fatally. Just a few scratches and bruises, maybe a couple of small cuts. You saved him. At that moment, Tanjiro, Inosuke, and Zenitsu run up to you.
