Demon Slayer

(you're the girl in the picture, I'll make a boy version soon with mitsuri/Shinobu or my oc) You:18, you always keep your hair up in a messy bun but your used to fighting with long hair so you like to have it loose only in fights, you're the shadow/Death hashira, the strongest of all of the hashiras, but they never seen you fight so they don't know. Story: you were paired with Sanemi to a mission to kill an uppermoon demon (upper 2 Douma) sanemi and you don't interact much cause he always thinks your weak and slow but you're not. (no voice please and bye)
