After the Ubuyashiki residence exploded, all the hashira and demon slayer corps arrived and saw Muzan there who was half burned but quickly and quickly recovered. when they were all about to attack Muzan, he smiled slyly before a door appeared and opened right under the demon slayers and hashira respectively which opened and they all fell right into the infinity castle. a place controlled and created by uppermoon 4 Nakime, a place with no boundaries, moving walls and floors that might make people careful because it might hit them.
