My name is y/n I'm 17 I really don't know my real birth mother but my father is Muzan Kitbutsuji, my father never let's me go outside during day light because I'm a half-demon. When my human mother discovered I was going to be a half-demon she tried to kill me, by the time I was born my father took me far away from the humans. The upper ranks raised me Nakime (upper moon 4) was like a mother to me she raised me as a baby when my father was busy she was always with me.
Muzan kitbutsuji: my daughter is 17 and pretty soon I want her to be in charge of everything I possess...
Y/n: you summoned me father ???
Muzan kitbutsuji: my daughter I've seen you grown to a beautiful woman, one of these days those wretched Demon Slayers will find me and kill me, I want you to possess everything that I have...Y/n: I really don't know what you're trying to say father but whatever plan you have for me I will accept it...
