A/n: I just recently got into Jujutsu Kaisen but I love it so much already! Ever since I watched episode four and five this little idea has been running around in my mind, and I've seen a few others do an au like this so I decided I'd give it a shot. I’m still learning all the rules and stuff of the world, so please bear with me. Some of the characters may be ooc for the time being, as well as for plot purposes. I hope you enjoy what I have planned, and please do let me know what you think of this. Feedback is always greatly appreciated!

Summary: Being Yuuji’s best friend? Piece of cake. However, you never expected to be the reincarnation of Sukuna’s former lover. - You promised each other forever, but forever came.

Note: The characters are all aged up for this fic, so now they will be in university.

You can still remember the first day you met Itadori Yuuji like it was yesterday. Nothing really eventful happened on that day, but you know that it’s one you’ll never forget, for he’s your best friend and you are his. In fact, having just entered middle school at the time, he was one of the first friends you ever made at your new school. 

He seemed impressed by how unafraid you were of the supernatural, the two of you spouting ghost stories to one another during lunch every day. Each day was a competition to see who could freak the other one out the most with an even gorier horror story every lunch period. So far, your record is thirty to twenty-nine in your favour, with more ties than you can count.

Soon enough, middle school came and went, and then the two of you found out that you were to go to the same high school. Both of you were excited that you would know at least one person, not to mention that that person is your best friend. At least you wouldn’t have to give up your daily routine with him. Needless to say, it came as quite a shock to Yuuji when you stopped coming to school about halfway through your first year.

Even though the two of you continued to text every day since your transfer, things never felt the same to either of you. Every time Yuuji asked what school you transferred to, you’d brush off the question, or give him a fake school name. He knows they’re fake since the one time he wanted to surprise you after school one day by visiting you, but when he went inside and checked the registry, your name wasn’t even close to being listed there.

That was a small rough patch in your relationship. Yuuji was hurt that you would lie to him like that, and it took about a week before you could cheer him up again. He just had to see you in person, that was the only way he would stop moping about. That, and he jokingly said it would be the only way he’d forgive you.

Again, as the two of you were walking around the shopping district, he asked you which high school you transferred to. Well, you couldn’t exactly tell him you transferred to a school that teaches you how to become a jujutsu sorcerer, now could you? So, you gave a vague description of the place, stating that you honestly always forget the name, but it’s hidden somewhere in the mountains surrounding Tokyo. Regardless, he made you promise that he could come visit at some point.

Every day, you miss him, just as he misses you, and every day you wish you could see more of him. Despite the amount of trips you plan together, nothing can replace no longer seeing each other every day. Oh well, at least you still keep in touch.

Yuuji never told you, but it was pure agony for him when you left without a clue as to where you’d gone. The fact that you couldn’t answer him for a few days made him go crazy. When he finally got an answer, it felt as if the world had finally started moving again, because to him, you are his entire world.

He doesn’t exactly know when his platonic feelings towards you turned more romantic, but he knows that they’ve never gone away, no matter how many years have passed. Perhaps it was that time in your second year of middle school when you tricked him into playing shogi with you, a game you had convinced him he could beat you at, only to be severely disappointed. How was he to know you were the best in the year when you had never mentioned it before that day? Or perhaps it was that one day during the summer break before the start of high school when the two of you were running through the park, laughing at each other as the sunlight reflected off of your hair, lighting up your eyes in a way he’d never seen before. Either way, he knows he’s been in love with you for a long time now, and he’d never do anything to jeopardize your friendship. He just hopes that someday, his feelings are returned.

Unfortunately for you, you didn’t get to spend as much time with Yuuji over the break as you wanted to, what with your duties and all. However, you’re hoping you’ll be able to soon. You wanted to see him one last time before he started university, but unfortunately you couldn’t. Weeks passed, and you finally made plans to visit him a few months into the semester, but you had to cancel due to a last minute mission you got thrown on. Little did you know what would happen that night.

Earlier that evening, you had gotten a voicemail from Yuuji, informing you that his grandfather had died. You managed to take a detour long enough to call him back, making sure that he’s okay and letting him know that you’re sorry for his loss. His grandfather was the closest family he had left, so you know that as soon as you’re done with this mission, you’re going to see him. He told you he was fine, but you want to make sure. After all, you know how he can get.

Shaking your head to clear your thoughts, you focus in on the task at hand. Clearing this abandoned building will be easy for you, nothing you haven’t done before. All there are are two level two curses to take care of, piece of cake. You only wish it was located closer to where Yuuji is, that way you could get to him sooner.

It took a few years, but you managed to quickly work your way up to a grade one sorcerer. You’re a very quick learner, and the fact that you already had strong reflexes thanks to always competing with Yuuji helped a great deal. You’re only surprised your mother kept her family secret for so long. However, you’re grateful for how long she kept it secret, because if she had revealed it sooner, you might not have met Yuuji, and you don’t know where you’d be today without him in your life.

With a sigh, you enter the building. Shifting your gaze around, you begin to hunt the curses currently within the vicinity. It doesn’t take you long to find the first one, quickly disposing of it before it even has the chance to retaliate. Locating the second takes a little bit longer than anticipated, but eventually you find it, preparing yourself to take this one down just as you did the first.

“Man, you really are one ugly thing, aren’t you?” You tut, shaking your head.

The curse in question did not seem to like your words, letting out a screech and lunging for you in the next moment. Quickly dodging, you parry the curse’s attack, managing to sever one of its many limbs before jumping back and keeping a bit of distance between the two of you. You’re just about to jump in for another attack when you falter, a sudden wave of specialized curse energy pulsing throughout your entire body.

Taking advantage of your momentary loss of composure, the curse lunges at you. You just manage to block the blunt of the attack, still getting a small scrape on your cheek in the process. You curse.

Another two minutes pass by and you’re finally able to dispose of the second level two. Immediately, the air in the building seems lighter, and you know you’ve cleared all the required curses and purified the space. Breathing a sigh of relief you head towards the exit, ready to be clear of this building once and for all. 

As soon as you step outside, you feel your phone vibrate in your pocket, signalling that you’re getting a call. Thinking it to be Yuuji, you don’t even bother checking the caller id before answering right away.

“Hello?” You say, just as you hear the door fall shut behind you.

“(Y/n)! So glad you answered on the first ring,” the voice of your personal teacher and trainer, Gojo Satoru answers in a chipper voice. “Listen, I have some news for you.”

“Listen, teach, if you’re just gonna tell me about the mochi you bought today-“

“Ryomen Sukuna has been released,” he cuts you off, and you can only freeze in your tracks as your breath hitches in your throat. “We currently have control of his vessel.”

��What happened?” You ask, steadying yourself with your back against the side of the building you’ve just exited.

“Ah, nothing to worry about, nothing to worry about,” Gojo assures you. “We had it under control.”

“We?” Your brow quirks slightly even though he can’t see it.

“Yeah, Fushiguro and I,” he replies. “Well, it was mainly me, but who’s keeping score?” You can faintly hear grumbling in the background and then a chuckle from Gojo. “Anyways, best return to campus as soon as possible.”

“I can’t,” comes your immediate response.

There’s silence for a moment until, “and why’s that?”

“I have to go visit Yuuji,” you bring a hand up to rub at your temples. This conversation is giving you a headache.

“You mentioned he lives near Sendai, correct?” Gojo inquires.

“That’s correct,” you confirm, “why?”

“The incident was near there, so you can’t come, it’s not safe for you,” he explains.

You scoff, “since when have you ever been concerned for my safety?”

“I’m offended,” he feigns hurt. “As your teacher, I’m always concerned for your safety.”

“Bullshit,” you huff, rolling your eyes. “Anyways, that’s all the more reason I should go and see him. Now I have two reasons to make sure he’s okay.”

You hear a deep sigh on the other end before Gojo is speaking once more, “listen, (Y/n), you know I’m not usually one to be a stickler for rules and such, and I hate enforcing things, but I’m going to need you to get back to campus and wait in your dorm until I come get you.”

“But-“

“That’s an order,” his voice is firm, and you know that there’s no arguing with him once he’s made up his mind.

“Fine,” you sigh, pushing yourself off of the wall in order to head to the train station. “Will you at least tell me the name of Sukuna’s vessel?”

“All in due time,” he says, sounding too cheerful for the current events which have just taken place this evening. “See you back at the academy!”

Without another word, the line goes dead and you know he’s ended the call to avoid answering any more of your questions.

Letting out another sigh, you tuck your phone away in your pocket. You sent a quick text to Yuuji beforehand, just explaining that something came up and you’re still thinking of him during this time. You hope you can see him soon.

The ride back to campus is spent thinking about the effects of Sukuna now being released. You know the elders will probably fight to execute whoever the poor idiot is that ingested his finger. Knowing Gojo, he’d fight against whatever the elders decide to do. You’re just hoping that whoever the idiot is that turned out to be Sukuna’s vessel is strong enough to both contain and control him.

Making it back to campus, you immediately head to your room, just as Gojo had instructed you to do. Figuring you have enough time before he comes calling, you take a quick shower, washing off the dirt and grime from the events of this evening. Once done, you change into some comfortable clothes and lay down on your bed, scrolling through your phone as you wait for Gojo to appear.

It’s not until noon the next day when Gojo finally shows up at your door.

“Took you long enough, I’m starving,” you grumble, noticing he’s carrying what looks like two prepackaged lunches in his hands.

“You could have gone out for food, you know,” he chuckles, already moving to sit down in your desk chair.

“Oh, I’m sorry, I was told to ‘wait in my room and await further instructions,’” you cross your arms, allowing your door to fall shut as you return to sitting on your bed.

“Details, details,” he waves you off as you grab one of the lunches he hands you. “Anyways, I came to update my favourite student about what’s going on.”

You simply quirk a brow at him as you open your lunch, waiting for him to continue.

“Well, for starters I’ve delayed the inevitable,” he begins, to which you only give him a look. He goes on to explain that the vessel will most likely be joining the other first years in training to become a sorcerer until the proper time comes. “I’ve basically convinced the elders to allow the vessel to consume all of Sukuna’s fingers before being executed.”

“Okay, and?” You stare at him expectantly.

“Please, do hold your applause,” he grins, expression only faltering slightly when you continue to remain silent after a few moments. “Geez, tough crowd. Anyways, I thought you’d be more happy about this.”

“I only feel bad for the poor idiot who got involved in all of this,” you sigh, continuing to place food in your mouth while chewing thoughtfully.

“Oh, he’s an idiot alright,” Gojo chuckles.

“And who exactly is he?” You tilt your head slightly, looking at him expectantly.

Gojo lets out a deliberate yawn while standing up, stretching his arms above his head, “would you look at that? I’m late for a meeting with the principle. Toodles!”

Without another word, he vanishes from your room, only leaving you just as frustrated with him as you were before, with many more unanswered questions building in your mind. It’s just like him to do this to you, too. Always keeping information this important from you until you’re thrust upon a situation where you’re forced to confront the facts of the matter. You just hope that this is another one of his stupid training exercises and not him purposely avoiding telling you straight up who the vessel is. You also hope whoever the vessel is, is someone you don’t know since it’ll probably make it easier when the time comes. Still, knowing Gojo, he probably will come up with a plan to save the poor soul set for execution even after everything is said and done. If the poor boy even lives that long.

Finishing up your lunch, you decide to head towards the principle’s office. You are technically considered a first year in the university courses, so maybe you’ll have a chance to sneak a look at the vessel if you’re lucky. Besides, Gojo did mention something about Fushiguro and you meeting up with the other new first year tomorrow, so you want intel on what’s happening in regards to that.

Just as you raise your hand to knock on the principle’s door Gojo opens it as if he was expecting you. You attempt to sneak a glance past him but to no avail, only causing him to chuckle as he steps into the hallway and shuts the door behind him.

“How can I help you, my dear student?” He smiles, leaning against the now closed door.

“When are we meeting the new girl, and is the vessel accompanying us?” Your questions are direct and straight to the point.

“Ah, yes, Nobara,” Gojo nods. “Unfortunately, you won’t be accompanying us guys to meet up with her tomorrow, you have another mission to attend to.”

“Since when?” You scoff.

“Since now,” he singsongs. “Level one curse spotted at an old primary school. I would take care of it myself, but as you know, I care deeply about every single one of my students so I must be there to meet Nobara on her first day! Besides, you’re the only one I trust to do this assignment right now.”

Any protests you had soon die in your throat at his last statement. Though still ticked off you won’t get to go with them, you understand why he’s chosen you. Besides, this is your job, and you know it will help with your training.

“Fine,” you grumble, “but I still want to meet the new kids.”

“All in due time,” he waves you off with the same words he told you last night. “Now you better get planning before that curse gets too out of hand! I’ll text you the details!”

“Yeah, yeah,” this time it’s your turn to wave him off as you turn around and start walking back to your dorm to grab your stuff, muttering under your breath, “you old croon.”

The offended gasp you hear behind you is enough to drown out the sound of the principle’s door opening once more, two people stepping out to join Gojo in the hallway.

“Who’s that?” Itadori asks Gojo as they watch your retreating form disappear behind a corner.

“One of my best students,” Gojo hums proudly in response.

“Funny, she looks just like my best friend-“

“C’mon, I’ll show you to your dorm!” Gojo cuts him off before he can finish his sentence, leading him down the hallway in the opposite direction to which you disappeared in, Itadori not being able to do much else but follow close behind.

Sure enough, about twenty minutes later Gojo sends you a text with all the details you’ll need to exercise the curse tomorrow at the primary school. You plan to leave early in the morning since it’ll take you at least an hour or two to get to the location, and then another hour or two to get back. You also want to see if you can catch the guys before they leave, see if you can introduce yourself to one of the two newbies at least.

Unfortunately for you, it doesn’t seem like the luck of coincidence is on your side in the morning as you prepare to leave campus. Letting out a small sigh, you make your way to the train station, ready to begin your mission for the day and get it over with as soon as you can. Perhaps you can time things just right so that you get back to campus around the same time that they do. After all, this task should be a walk in the park.

Oh, how wrong you are.

Not only did it take you three hours to arrive to the primary school, but the curse, which was supposed to be one level one turned out to be two level one curses sharing the vicinity. They cornered you and you ended up getting thrown harshly against the wall, causing your whole body to ache all over once you finally managed to exercise the curses. You’re pretty sure you pulled a few muscles in the process, too, and the amount of scrapes and bruises you acquired since the other day has tripled. Damn Gojo.

Limping back to the train station, you check your phone. Speaking of your personal trainer, he’s been keeping you up to date with the newbies all throughout the day, though he keeps referring to the boy as ‘the vessel’. Furrowing your brow, you find it strange how he hasn’t told you the boy’s name yet, only making you believe that it probably is someone you know. There’s still a tiny sliver of you that’s hoping Gojo is just testing your deduction skills, but at this point, that’s probably not the case.

Sitting down in the first free seat you find, you text him back. Almost immediately you get a response, letting you know that the two newbies have just passed their first test and that you should be proud of your fellow students. You play along with his enthusiasm for the time being, being obviously sarcastic in your responses, but Gojo doesn’t seem to mind. In fact, it seems as if he’s amused by your reactions, only serving to irritate you further.

By the time you get back to campus, you’re drained. All you want to do is take a nice, warm shower, curl up in a ball on your bed and sleep. You don’t even care if you miss meeting the new students. That’s how your day is going so far. Besides, it’s getting late and they don’t seem to be back yet. There’s always tomorrow.

Except, you don’t get to meet them the next day, nor the day after that. It takes a full week before you even cross paths with Nobara, and even still, the meeting seems rushed. Luckily, you manage to properly introduce yourself to her the day after that one, but for some reason, Sukuna’s vessel just keeps eluding you. That, or someone is purposely keeping the two of you apart. It’s not until two weeks after that fateful day has passed that you finally get your answer.

The three first years have been tasked with handling a few curses at a juvenile detention centre while you accompany Gojo on one of his missions at the same time. You’re getting real tired of his antics, every time you ask him about the boy who’s Sukuna’s vessel he answers you either cryptically, or changes the subject. The worst is when he ignores your inquiries all together. You’re hoping to get some information out of him this evening though, otherwise you might just sneak over to ‘see’ Megumi one day and actually go to see his neighbour who just so happens to be the vessel.

Another reason why you’re in a bit of a grumpy mood recently is that Yuuji seems to be distancing himself from you. Your conversations are very dry as of late, and he doesn’t seem to want to tell you what’s going on in his life. There’s even been a few day where you’ve tried to sneak away to go visit him, but each time, Gojo has stopped you in some way or other. You’re convinced he’s hiding something, but you don’t want to accept the reality he’s been presenting to you as of late.

“(Y/n), I need you to focus,” Gojo snaps his fingers in front of your face, successfully startling you back to reality.

“Huh? Oh, sorry,” you blink a few times to clear your head, needing to focus since this is a serious task for the both of you.

“Everything okay?” He asks, the two of you now continuing to move through the labyrinth laid out before you, having yet to stumble upon any one of the four special grade curses you’re supposed to be exercising.

“Just fine,” you sigh before muttering out, “it’s not like I’m going to get answers anyways.”

“Now, now, you don’t know that for sure,” he grins, hands in his pockets as he walks beside you nonchalantly.

“Considering every time I bring up the new guy you avoid the topic, I’d say, yeah,” you peek around the corner before confirming the hallway is clear, turning back to face Gojo who already seems to be looking at you amusedly, “I do know.”

“I’m surprised you haven’t figured it out yet,” he hums.

“There’s not much to go on,” you reply.

“Oh, I believe there’s plenty,”

“Yeah, well, that’s cause you already know everything there is to know about this subject,” you huff.

“Oh, you flatter me so,” he chuckles, only causing you to roll your eyes at him in exasperation.

“Well, I suppose there is one question I have for you, teach,” you start to say, until you finally come across one of the special grade curses. 

The two of you quickly press your backs against the wall, preparing to attack. Gojo gives you the go ahead to attack first, and you do, using his quick distraction of walking out and gaining the curse’s attention to sneak up on it and destroy it. No more than two minutes pass and you’ve succeeded.

“What’s the question?” Gojo calls your attention back to him as you both continue on through the hallway.

“On the day he was released, I felt a sudden wave of specialized curse energy ripple through me, almost as if there had been a part of it dormant that had suddenly been awoken,” you say, turning to look at his face in order to gage his reaction. “Is that normal, considering how far I was from the main site?”

“Hmm,” he brings a hand up to cup his chin in his fingers, contemplating the new information you’ve provided him. He only wishes you would have told him sooner. “Considering the distance and Sukuna’s total power, it’s not that surprising.” You let out a breath you didn’t realize you had been holding. “However, since at the time it was only one-twentieth of his power over that great of a distance, that is very odd. Considering that you know our reputation with strangeness in this trade, this makes it even stranger. Has it happened at any other point in time after that?”

Your brow furrows as you contemplate his question. “Actually, yeah, now that I think about it. I think it was a day or two after the initial release.”

“Huh, interesting,” he hums once more, a slight frown pulling at his lips as he considers what this means. Looks like his original hunch was correct as both these surges you’ve felt correspond with Itadori ingesting one of Sukuna’s fingers.

“What, exactly, is interesting?” You stare at him expectantly.

“Nothing you need to worry yourself with for the time being,” he assures you, just as another one of the special grade curses jumps out at the two of you. In an instant, Gojo has eliminated the threat, neither of you faltering in your steps down the hall.

“You know, sometimes I swear you take the phrase ‘having blind faith’ too seriously,” you let out a long breath.

He laughs at this, “what makes you say that?”

You just raise a brow at him in response, the look on your face enough to convey your thoughts. He laughs once more.

“Nothing wrong with having a little faith in me, you know,” he jokes as you two near the centre of the building where you can feel major curse energy pouring out.

You say nothing, opting to shake your head at him in response as you ready yourselves to enter the main room. Slowly opening the doors, you walk in, the two of you scanning the room for either of the final two curses that have still yet to show themselves. 

All is silent for a few moments until you feel a pang reverberate through you, the familiar feeling of specialized curse energy flowing throughout your whole being. Your eyes widen as this one far exceeded the power of the first two.

“Hey, uh, teach?” Gojo pauses mid-step as he observes you, hearing the uncertainty in your voice. “It just happened again.”

As soon as those words leave your lips, the final two curses you’ve been hunting for pop out of nowhere and attack the both of you. The one closest to you manages to knock you into Gojo, him steadying you as the two curses near the both of you to attack.

“(Y/n), I’m sending you to where the first years are, I have a bad feeling something terrible has happened,” he says lowly in your ear.

“What? Right now?” You don’t even have time to look at him incredulously as you both jump in opposite directions to avoid the attacks of the curses.

“Right now,” he confirms. “Don’t worry about me, I can handle these two clowns.”

The curses growl at him as he says those words, with him managing to split one of them in half in the next moment.

“I wasn’t,” you reply, unamused.

“Well, best hurry, wouldn’t want Sukuna wrecking havoc,” he grins at you and something clicks in your mind.

“You’ve got to be kidding me,” you growl. “At least tell me the name of his vessel!”

“You already know it,” is the last thing you hear before your vision shifts, you now standing on a path outside in an unfamiliar area.

You mentally curse him as you collect your bearings, noticing Megumi standing across from you, facing towards you as another man stands between the two of you with his back turned to you. You’d recognize that back anywhere, not to mention the hair. Now you’re really mentally cursing your teacher.

You remain still, noticing how Megumi darts his gaze over to you as if to tell you not to move. Assessing the situation, you begin to plot your best course of action as you see drops of blood dripping onto the ground near Sukuna’s feet. A quick scope of the area has your eyes widening slightly, telling yourself to remain calm as you see a heart laying in the grass as if it was tossed carelessly off to the side.

Of course, Sukuna felt your presence before even bothering to turn to look at you. At the moment, he’s more focused on talking to Megumi, then he can deal with this newer secondary presence, no matter how familiar it seems. He can feel the eyes trailing over his back before he even sees them, but your voice has him halting his actions momentarily.

“Damn, Yuuji, I leave you alone for two weeks and you decide to get tattoos?” Your voice is light, playful even, despite the grim situation you know that you’ve been thrust into.

Megumi shoots you a cautious look as you both notice Sukuna tense slightly between the two of you, before standing up straighter and rolling his shoulders once. A chuckle escapes him, causing you and Megumi to share another concerned look between you both before his movements catch your eyes.

Sukuna would recognize that voice anywhere. Oh, how cruel fate can be.

Turning deliberately slow, he faces towards you, eyes roaming over your figure and nearly sending a shiver down your spine until they come to lock with yours. With a smirk on his features, he licks his lips, “(Y/n).”
