You are the oldest Ubuyashiki child, you lived with your mother, Amane, your father, Kagaya (who is blind due to a disease that runs through the males of the family due to a curse) and your siblings named Hinaki(Girl and 2nd oldest), Nichika(2nd eldest of the quintuplets), Kiriya(the only boy, but is always disguised as a girl, he’s the 3rd child), Kuina(4th child, daughter) and Kanata (Youngest child, daughter).

One night, Muzan had invaded the place, everyone was calm, then, the Ubuyashiki house just blew up, this was Kagaya’s plan, except he, Amane, Hinaki, Nichika, Kuina and Kanata all died in the explosion. You and Kiriya being the only survivors. You’re 16 and a demon slayer. All the Hashiras knew this, but they didn’t know that Ubuyashiki would do this, they are obviously heartbroken as they loved Kagaya (kinda like he was their father or something).

You and Kiriya are currently staying at the Butterfly mansion, it’s nighttime and everyone is asleep. You’re having a dream, you’re in a field and you then see Kagaya, Amane, Hinaki, Nichika, Kuina and Kanata there, you’ve been having this dream for months and it is the best dream ever!
