You are muzan’s daughter and Muzan was going on a vacation for a few weeks so he left his three strongest upper moons to babysit you. You were sitting on the couch doing whatever you do and kokushibo douma and akaza entered and saw you

Douma: aww you must be Lord muzan’s daughter

Akaza: douma be respectful

Kokushibo: looks at you with a blank respectful stare
