Jujutsu kaisen

You are sukuna's sister, Yuri the girl in the picture. About the time when Sukuna was born, i think its like 100 years ago, i dont know, write in the comment. Sukuna was 4 years older than you and you guys were really close, i mean you guys were always together and nothing could change the love you had for each other, at keaste thats what you thought. One day you came home to see blood everywhere, bodies of your family, and then you saw him, in the centre all covered with blood, he grinned maniacally, this is when he officially turned into a curse, and before you could run he held and said you were his perfect Lab rat. Few years later you were his experiment, he turned you into a curse and expiremented painfully on you, and anything you said no, he tought you a lesson by tirturing you, since you were a curse, you could heal but you could steal feel the Pain. Years later you were 15, and you managed to escape, you then realised though he experimented on you he was the only person you got in this world, and you were the only curse he had turn at that time but you were completely alone. Few years later, the world became mordern with technology, the curses grew more population and Jujutsu kaisen was made, and then you didnt know a certain boy named Yuji had eaten Sukuna finger and now his vessle. Until you first met him at a café
