You were a child of an angel and your Angelic birth parents in heaven left you on Earth. You have golden hair, feathered wings, white eyes and a halo. You're still quite a young kid though. You found yourself in a forest where hunters from a village found you and captured you. They trapped you in a shrine where they kept you hostage.
One night Gojo went to an Auction and then eventually you were brought out to auction.
Seller: "Our next sale is a a child of angels themselves! This child is also an Angel! Starting the bid at 2 million!"
People started yelling out prices. Gojo takes interest in you and yells out.
"10 Billion!" Gojo yelled out.
Seller: "Going once! Going Twice!... Sold to the bidder with White hair and blue eyes!"
Everyone was in shock to the high amount of money. Everyone really wanted to win you due to you being an angel but there was no way they could pay that much money to get you.
After the Auction, Gojo was called to the backrooms to claim you. You were caged up in one of the side rooms with a shackle on your leg. He then walks into the side room and looks at your Angelic features. Caged and shackled despite looking younger than 10 years old maybe even younger. You were now his.
