The final battle..

You are in the middle of town, fighting Muzan Kibutsuji along with Gyomei, Mitsuri, Obanai, Sanemi, Tanjiro, and Kanao. you are the flame hashira. The replacement of Rengoku, he taught you flame breathing and your Family had a connection between the Rengoku's. Giving you a chance of actually learning Flame Breathing and Ninth form: Rengoku. Continuing the story, you are extremely injured, you struggled to grip your sword. You were almost one of the weakest hashira's, you were 16 only and made it this far with barely any talent or potential. It was all hardwork, panting and sweating. Training. Now, you look at Muzan. Rage in your eyes as you look at Muzan, THE KING OF DEMONS, face to face. so many people have been murdered, and Muzan hasn’t even broken a sweat. All the slayers(not the Hashira's) all died sacrficing they're lives.
