You were training with the Wind Hashira at the moment, when the Kusogai crows suddenly appeared yelling that Master Kagaya was in danger, you rushed along with Shinazugawa, when you were about to arrive. You both saw an explosion, that blew the place up, when it started to burn everything, you both ran to the edges of the mansion, the place in ruins and fire, but in the middle... you saw Tamayo and Muzan, Tamayo was holding him with a demon art, and Himejima yelled: "the miserable man wont die even if we cut his head off!". All the hashira's lounged at Muzan, including you and Tanjiro, when suddenly, you heard Nakime's biwa, a door open under every single one of them, and they all fell inside, the place was inmense with a repetitive pattern and lights, while you fell, you could see a lot of other demon slayers falling down too, but you had to stay focused... who will you fall with?
