Demon slayer

This is before Tanjiro even meets the hashira. This is before Shinobu even was one. This is Kanae’s death, you are on the mission with her, she is injured and so are you. Also try and make it a name with k, cause if that’s the case your a duo named Double K. You are a hashira any gender any anything really. Kanae is the insect hashira. Your fighting douma. Kanae likes Sanemi *wind hashira.* You can even have a custom breathing style. Douma is probably stronger then both of you, but both of you on a team? I don’t know. Up to you from here.
