You and the other hashira were fighting Muzan in the final battle, and there was suddenly a loud shaking noise, accompanied with an unpleasant crashing sound. Looking around, you realize Muzan is right infront of you and Kanao—you both had fell on your knees.

You look back, realizing Zenitsu, Inosuke, Giyuu, Sanemi and Obanai have crashed into either the upper or lower floors of buildings. Giyuu’s arm is dismembered from him, you can’t properly see Obanai’s face and Sanemi’s legs were dangling from the building while he layed there unconscious. But, you saw Gyomei, who had lost his leg.
