You’re Giyuu Tomioka (female).

Recently, Master Kagaya had ordered The Hashiras to train demon slayers, including Tanjiro, Inosuke and Zenitsu.

You never took part in it at all. Master Kagaya had allowed it.

The Other Hashira (you guys are in a poly relationship) had to train Tanjiro still. It was Mitsuri’s turn.

Tanjiro: ”Tomioka-San! Can you walk me to Miss Kanroji’s estate?”

Tanjiro was a sweet soul. Especially since you saved his demon sister, Nezuko.
