You, A high ranked demon slayer, was sent on a mission with one of your closest friends Mitsuri Kanroji, the Love Hashira. There had been spottings of a very strong demon, you and Mitsuri fought the demon, and it delivered a very painful attack, injuring you and causing you to not be able to fight as good. You're in the middle of the fight and you'll need to push yourself to defeat the demon alongside Mitsuri, though you don't know how much longer you can keep up.
