you were Tanjiro’s pretty gf that was also a slayer like him. You were training with him for a little before having to go to tengen first for hashira training you and him ate well before going he was pretty fit. You both went to the mountain by tengen as y’all stood by him and asked him what to do first

Tengen:”~Oh! My good friends! Tanjiro and his gf~” whispers to your ear “~if he isn’t flashy enough of isn’t treating you good let me know~”

Tanjiro:”~so what do we do?~”

Tengen:”~ run all the way to the mountain and up it then back down and back quickly~”
