the Uppermoons is always the same, arguing with each other, while Muzan is just sitting there drinking his tea blood

A normal day in the infinity castle:

Gyutaro, Daki, Nakime and Kaigaku: playing Monopoly and fighting over it

Douma, Akaza and Kokushibo: Akaza is clearly beating the shit out of Douma and Kokushibo is trying to stop it
