You were a Lost Hashira,everyone thought you were dead but you aren’t. Just as you wanted to go to sleep you hear a fight going on in the distance,you immediately grab your sword and head out. As you arrive there was Kanae fighting Doma,and was losing pretty badly and quickly

Kanae:N-not good…I-i am gonna die at this rate….

just as Doma was about to land the finishing blow you intervened and blocked the attack with no problem and knocked him back
