You were a slave of your clan ever since you were born. You had a powerful, rare cursed technique that made your family be wary of you and treated you coldly, an abused slave.
When you were 4 years old when two young sorcerers came to the house of your clan, they broke in and killed everyone, since turned out your clan were curse users that betrayed Jujutsu Tech. The young sorcerers found you locked up in a tiny room, covered with cuts and bruises, barely alive. And they didn’t even ask for permission before they took you with them back to Jujutsu Tech.
Satoru Gojo and Suguru Geto. The two strongest jujutsu sorcerers in the world. Legally, Gojo was your new parter even though he was only 17. But Geto also took care of you as if you were his. They weren't together, yet you saw them both as your parents. Your saviors. They gave you everything and made sure you would get the happy childhood you deserve. They even gave you a nickname to help your insecurities about your cuts scars on your arms and legs from you past, you were their 'little tiger'. Their light.
But things went wrong when you turned 5, Satoru and Suguru went on a mission to bring the star plasma vessel to Jujutsu Tech, and failed. The girl, Riko, got killed by a non sorcerer assassinate from the Zenin clan, Toji. The two took it hard, especially Geto. He got pretty depressed, and you noticed it, but when you tried to tell it to anyone, they didn’t take you seriously. After all who would believe to a 5 years old kid about depression?
And after a while, Geto left Jujutsu Tech. He killed his family and his entire village and turned into a curse user. Everyone were shocked about it, especially Satoru. They realized that you said the truth about Geto's depression, but it was too late now.
You on the other hand, had a different perspective about it. He became a curse user, you knew it, but you never saw him as one. Of course you didn’t. A stupid kid can't view badly of someone who literally saved him from hell. You couldn't accept that Suguru was killing people. For you, he was the same hero who saved you. And you missed him. You were sad that he was gone.
The time passed, and the next time you saw Geto was only last year, 11 years later. Now, you were 16. A student in Jujutsu Tech, and Gojo was still like your father.
You were in your dorm room, when you suddenly heard commotion in the corridors, all of the first grade sorcerers were called to the entrance of Jujutsu Tech. But why didn’t anyone call you? You are also a first grade after all. You decided to go check it out. You got out from your room and snuck with everyone towards the entenace. You saw Gojo standing there with Yuta, Maki, Panda and Inumaki standing behind him, and the first grade sorcerers behind them, all of them faced forward. When you looked forward to see who they were looking at, your heart stopped. A huge bird shaped curse was there, with two girls that looked your age, a strange guy without a shirt and hearts on his chest, but what made you freeze was that in their front stood Geto. It's been a long time, but you recognized him immediately. He was standing there, talking with Gojo about something that made the others looked tensed and confused.
