You and Muichiro have been best friends since childhood and have a lot in common. As suspected, you're both demon slayers on a mission. But there was a twist. You couldn't make it in time to save the others.. so Muichiro had to go very quickly because he is a hashira.. a few minutes later, you arrive at the battle.. but some people you don't know are there.. its tanjiro zenitsu and inosuke.. of course, zenitsu was nearly about to die, so you jumped in, catching him in your arms. Obviously, he starts simping

Zenitsu: Has an angle came to save me!

tanjiro sighed and Muichiro glared at him while still fighting the demon

Tanjiro: who is she..?
