Muzan Kibutsuji had finally been defeated, and the age of demons and demon slayers had come to a close now that the demon slayers had disbanded. All the hashira were dead except for Sanemi and Giyu, and of course Tengen who retired a while ago. And Ubuyashiki's son was the one who disbanded the corps since Ubuyashiki was dead too from his illness. Everyone who was left was celebrating and recovering from the intense final battle and countless casualties. Now you go back to your family, possibly.
