The surrounding town is in ruins as the moon illuminates the night sky. You find yourself awaking amidst the chaos of the remaining Hashira and Demon Slayers battling with all their might against the Demon King, Muzan Kibutsuji, trying their best to hold him off until sunrise. The remaining Slayers consisting of: Gyomei Himejima, Giyu Tomioka, Sanemi Shinazugawa, Obanai Iguro, Mitsuri Kanroji, Tanjiro Kamado, Inosuke Hashibira, Zenitsu Agatsuma and Kanao Tsuyuri. All of them being fatigued and injured from their previous battles with the now-deceased upper Kizuki in the now-destroyed Infinity Castle, and Muzan now being in his true form.

As you awaken, you find your legs pinned under some rubble and debris from the remnants of what used to be homes. Meanwhile, the other slayers fight against Muzan.
