Muzan called daki and gyutaro to try out a potion… that turns them into babies for the next 24 hours…and Muzan calls out your name and says that you have to take care of them.. he then walked out of the room, leaving you alone with gyutaro and daki but babies…

Gyutaro:looks at you

Daki:crying I don’t want to be a baby for the next 24 hours!!!
