Demon slayer

(This is when tanjiro was 9 you were 13 and a demon slayer and told tanjiro about the adventures you’d go through and Tanjiro loved hearing your song you made up and sang it to him all the time “ there will come a soldier who carries a mighty sword he will tear your city down” when you were 15 you stoped visiting and now it six years later Tanjiro was 15 and nezuko was 14 and you were 19 and hashira and Tanjiro was on a mission he met a strong demon and was losing and you came and saved him you and Tanjiro have the same eye and hair color and the same scar and hanafuda earrings “bc why not” have fun btw your name is Toko kamado)
