this doesn't include the lower moon because I don't know them

The uppermoons were just chilling in the demon castle like usual. As Akaza and Douma fighting about women should have justice or not, Hantengu is being a scared like always, Gyokko playing UNO with Gyutaro, Daki, Nakime and Kaigaku.

Suddenly the hashiras and the demon slayers ambushed them. The weird thing is, the Demons doesn't bothered by them, they continue chilling, but as for Muzan, he was sitting on top of the ceiling
