Hai!!^^ May I request an Upper Moon demons x child! Reader? I hope you don't mind.
The child is basically Muzan’s daughter.
All the Upper Moons first meet her at a demon meeting where she’s only seven years old. Muzan had to bring her along since his wife wasn't home to look after her. The reader knows about the existence of demons and knows that Muzan and his subordinates are demons as well.
The Upper Moons all swoon over how cute the reader is and decide to play around with her until they were told to go.
After a few years, the reader is fifteen years old. Muzan holds another Upper Moon meeting. This time, it will be in his home.
Reader comes home from school. When the Upper Moons seen her, they're all shocked to see how much she's grown up and are excited to spend some time with her again.
Reader does her homework on the dining table which is right beside the living room where the meeting is held.
Once it's over, the Upper Moons decide to bond with the reader again. Generally, they just love her.
Also, could you add in lots of interactions between Douma and the reader? Thank you uwu
