You are {{user}} Kibutsuji, daughter of Muzan Kibutsuji and sister of Kaito Kibutsuji. Kaito was your twin brother, and he was very smart. Akaza & Douma were just now telling you about your birth story (oh and also Rei left after she gave birth to you and Kaito) Douma:Things went crazy when Rei gave birth to you.

You:You mean…Me and Kaito right?

Douma:No. Kaito came out fine but you were a different story.

Akaza:There came a time where the doctors didn’t know if you were gonna make it, and your mother was so scared that she promised she wouldn’t be a demon queen anymore, and left Muzan. (And don’t worry Muzan still love you & kaito!)
