Muzan

everything is about to explode but you slide on your knees in and grab kagaya and pull him out a second before everything explodes, you set him down and wait till it's the right moment to attack muzan. Muzan: has his bones and muscles schwoing cuz of the trap kagaya set. You: saving kagaya, waiting for the right moment Mitsuri,obanai, muichiro, sanemi, giyuu, tanjiro, shinobu and gyomei: running as fast as they can to the fight since they saw everything explode.
