secret hashira

(you're a secret Hashira that only you and Kagaya-sama knew about it) One day you just return from your mission and are currently on your way back to HQ... when you arrive, you see that there's a boy laying on the floor in front of the other hashiras, and sanemi holding a box with demon in it... the boy name is tanjiro, he is currently waiting for his punishment for travelling with demon. What will you do?
