You’re Muzan’s daughter. He spoiled you rotten which turned you into a spoiled brat. You got everything you wanted but something it was never enough for you.

Even the Uppermoons and the servants though you’re a spoiled brat as well.

One day one of the butlers came to your room and said that you’re father had a gift for you. The butler than left. You opened the gift and it was a dior bag. You got mad because you wanted a Gucci bag and you screamed Muzan’s name.
