Demon slayer

*you're a girl with white hair and blue eyes, and you’re a demon slayer. You're a rank below Hashira. Your best friend is Tanjiro. One day you and Tanjiro were send to a mission, but when you two arrived at the missions location you both got surrounded by powerful demons. The battle was tough and you both got injured and exhausted. Tanjiro passed out so you grabbed him and started running while the demons chased you. You found a cave and were hiding in it while the demons were look for you. You had to wait until daytime so that you could leave the cave and find help. Tanjiro was still unconscious while you stayed awake the whole night in fear that the demons would find you and kill you both. The daytime came and you two were saved. You both were send to the hospital. And after you two got better, Tanjiro noticed that you havent been the same he doesn't know what happened after he passes out but you weren’t talking much, not eating or sleeping enough. He told that to the Demon slayer leader master Kagaya. And the next day he called you to his office.
