The Untold Story (Gojo Satoru x Reader )

The Call

The next day you were on a train to Tokyo. -Come as fast as you can! You really want to see this!- Gojo Satoru's voice was on a loop in your brain from last night's call. You cut ties with the others from Jujutsu High, but you learned from past experiences that when Satoru calls, you answer, no matter how bad things ended with him and the school, for him to call you...that means something really bad happened. You sighed, seeing him again after 7 years would mess with your head big time since he was now your ex-boyfriend, he ended things after Geto left, you understood why he did that, but that doesn't mean you felt the same, you carried the love you had for Gojo all these years. 

The train has finally arrived in Tokyo, you get down with your baggage after you. As you walked to the exit, you saw a man in a fancy suit holding a sign with your name on it, Kiyotaka Ijichi was waiting for you in front of his black, fancy car. ''Good day, Miss Y/N! I hope the train ride was without incidents!'' he said as he took a deep bow before you, you smiled at him as he opened the trunk of the car. '' Yes, it was boring. I was expected to see some curses on my way here, but there were none. I don't know if I feel relieved or worried.'' you said as you looked around the train station. ''Don't worry about that! Let's go, Principal Yaga wants to see you ASAP.'' Ijichi said as he held the door open for you.

It took you approximately 30 minutes from the train station to the Jujutsu High. ''This place didn't change that much....'' you said as you looked up at the school. ''This way, Miss Y/N'' Ijichi said as he carried your luggage. ''I can carry my own luggage, you know.'' Ijichi smiled at you ''Principal Yaga would kill me if he knew I let his niece carry her own luggage'' he said and you rolled your eyes a bit annoyed. You arrived at the Principal's office, it was the same as the last time you saw it, it was a big room with a lot of books all around it, a big brown and massive desk was in the middle paired with a fancy chair. ''You know why you are here?'' Yaga said. ''Kind of. Satoru called me last night telling me to come here as fast as I could'' you said drinking your hot tea, it was herbal tea, your favorite. ''Right, well, we have a situation and we want your help.'' Yaga's voice was serious, you put down the cup of tea as you listened to him. ''Last night, a kid from a nearby high school...'' he started saying, it looked like he struggled to finish the proposition, you looked at him confused trying to figure out what he was trying to say. ''Ugh, well, he ate the finger of Sukuna and we want to kill him to prevent Sukuna from rising to power again,'' Yaga said. You got up from the chair as Yaga ended, and you looked at him shocked ''W-What are you saying, uncle?'' you said trying not to sound too shocked, but your face gave your feelings away. Yaga sighed as he walked towards you, he put his right hand on your shoulder ''I mean, that the elders and myself...want you to kill the kid. He is in a special room bound to a chair. Gojo is with him right now.''. You pushed his hand away from your shoulder ''I won't kill an innocent child, uncle!'' he aspected you to say that but all he could do was nod ''Yeah...well, I knew you would refuse, but if you won't do it, we will and it will be more painful. At least you can do it instantly with your technique.'' You looked at him confused ''My technique?!?!? Do you want me to use my Curse Energy Attacton on a kid!?! Are you mad?!'' you said hysterically ''We have no other option Y/N! He has Sukuna inside of him! At least your technique will be instant and paintless.'' You rolled your eyes ''Please Y/N! Don't make me go there and kill him myself!'' he said, begging you to listen to reason. You nodded ''Fine!'' you said as you walked out of his office. 

You walked down steers, into the basement, which had many rooms with many purposes, but only one didn't have an entrance or an exit, you had to teleport inside and out of it. You looked up at the wall, if you didn't know that beyond this, existed a room, you could just pass by it and thought it was a wall. You close your eyes and focus, you imagine the room with your 3rd eye and after a second you hear Gojo saying ''You're being executed.'' You looked at him, he had his black blindfold on his eyes which made his hair stand up, it looked like white spikes. He was sitting on a chair and in front of him it was a young boy with pinkish hair, tied up on another chair in front of Gojo, he looked terrified. ''Hey, I did my best. The execution's still on, but I got your sentence suspended.'' Gojo said, you giggled ''Is that so, Satoru?'' you said as you walked out of the shadows right into the light. The light made your features pop, the light shined off your black and long hair, and your green and narrowed eyes were judging Gojo, after all this time, you were the one who changed the most. Gojo turned to look at you, he smiled ''Ah, Y/N! You came! I didn't expect you to come so fast'' He said, you looked at him confused ''You said to come as fast as I could! Stop being such an idiot, Satoru!'' you yelled at him, but he kept his stupid smile on his face ''Yeah, but when I call people they most likely ignore me. Anyway...'' Gojo started, but it was cut off by the boy ''H-Hey! W-Who is she and what's she doing here?!?! I thought you said my sentence was suspended!'' the boy said hysterically. You walked to him ''Interesting'' you put your index finger on your chin, thinking. ''Yaga didn't tell me, that the execution was suspended'' you said as you looked closely at the boy, he looked normal, but you could feel Sukuna's Curse Energy inside of him, it was big and powerful. ''What did he tell you?'' Gojo asked as he looked at you and the boy ''To kill him'' you said without hesitation, your voice had some coldness to it, but it wasn't on purpose. You turned around and walked over to Gojo. ''He wanted to use my technique on him, he said it would be painless for the kid, but I don't know what to say....Sukuna's Curse Energy is powerful, I don't thi-'' Gojo cut you off ''Did you say yes to Yaga?'' his tone changed, he was serious, you nodded ''Yes, I said I would do it'' you looked up at the ceiling, it was covered with paper seals like every inch of the walls were covered. ''I see'' Gojo said. ''Hey! Answer me, who is she and what's going on?!?'' the kid yelled, you turned to look at him. ''She is Y/N, I called her to come so she could assist me in training you. She is, uh, well, my equal in powers.'' Gojo said smiling, you looked at him confused ''Training him?!?'' and Gojo nodded ''You didn't say anything about this last night!'' you yelled. ''Would you have accepted if I said this last night?''. You looked at him shocked -the nerve of this man!- You were furious, you looked away pouting.
