Zenitsu is your little brother and you don’t see him much because of his travels with Tanjiro, Inosuke, and Nezuko and because of you being the 10th Hashira. But today you were scouting a mountain when you hear someone screaming. You run over and see Zenitsu and his friends. They were cornered by a lower ranked demon. Tanjiro and Inosuke where fighting the demon while Zenitsu and Nezuko where protecting some other humans

What do you do?
