Diamonds are forever.
JJK x male!reader meant to be platonic one shot.
Cw: slight body horror/mutilation. Minor self harm, but only mentioned once. trying to leave ending ambiguous (because I don't wanna continue writing this) if someone else wants to write an actual fic for this go ahead just link my post/credits either works. Also shit grammar. And definitely slightly ooc sorry for that.
Divider Credits.
• You'd always been raised by a materialistic family.
• Money mattered more than whatever the hell you were doing.
• You never really showed how you felt on your face either.
• You had emotions, but they were internal not something you showed on your face.
• Yo never spoke of them, but you could see cursed spirits.
• Your parents were later killed by a curse.
• It spoke to you and you stood there expression blank.
• For some reason despite knowing how you should feel you weren't scared or sad.
• Sure your parents weren't loving, but they were still your parents.
"Would you like me to give you one of their eyes so you never forget them?" The curse asked in that horrid voice of its. You stood there and raised your open hand. "Why take one of theirs when you have twelve?" You asked and in that second you realized you were feeling angry. So angry, you tore out the eyes of the cursed spirit in front of you.
• The cursed spirit screamed slashed you under your eye, and in the end you tore it limb from limb.
• Suddenly every body part turned into diamonds.
• You touch your bleeding cut under your eye, and for some strange reason you shove the diamond that was the curse's eye into it.
• It was a mistake. It hurt like hell and you screamed. Yet there it was another eye in your skin.
• It functioned just like your other eyes.
• It scared you so you dug it out.
• Back to being a diamond it sat in your hand covered in your blood. Where the eye had been now just a cut.
• You left your house and wandered.
• You bumped into a tall muscular man who looks down at you.
• He kneels down because he's curious.
• He can feel the cursed energy seeping off of you in waves not as strong as the six eyes, but it's still impressive from a kid who's 7 or 8 at most.
• He sees a shiny object in the young boy's hand.
"What's in your hand?" He asks as you hold out the diamonds. "A monster." You reply as you turn the diamonds over in your hand.
• The older man looks at your like your stupid.
• This leads to you putting the diamond you previously had shoved into your cut back into the cut.
• You tear up from the pain, but you have three eyes again.
• In that second you saw the man before you with a hole in the side of his body with a white haired boy looking at him.
• The man looks at you in shock. He can see the third eye, hell he watched it form.
• That wasn't possible unless your cursed technique was actually manipulating your physical body into becoming the curse that you put in your body.
• That was impressive.
• Maybe you'd be useful once you were a little older.
"My name's Toji, what's yours kid?" Toji asks you as he stands up. There was something about him that made your eyes shine.
• After that you ended up finding a 19 year old woman before you.
• She wore a traditional miko with black hair in two pigtails.
"You've been missing for a while." She says as she kneels down to speak to you. You just look down at the diamonds in your hand. "Your parents are... Gone, right? Do you have any relatives to live with?" The lady asks you as you shake your head. "No... Are you hunting that monster?" You ask as her as she looks at the diamonds. Cursed energy spills from them as if they are made of a curse. "Yeah I am." The lady smiles reassuringly.
• You look down at the diamonds made of the curse.
• You place the diamonds in her hand and she looks over them.
• The lady is unsettled by you. Your cursed energy is just overflowing.
• No expression just... Blank.
• The diamonds now in her hand don't help either.
"Why are you giving these to me?" The lady asks you as you look at her like she's dumb. "I tore up the monster. Now it's like this..." You say as you pick up the diamond that was the monsters eye and put it in the healing cut.
• The lady looks at you before screaming loudly.
• After a few moments she calms down and kneels beside you.
"I'm Utahime Iori, and you are?" Utahime asks as she looks down at you. "I'm (Name)." You say as you look down at the ground.
• After that Utahime was basically your older sister.
• You'd annoy her, get parented by her, poked fun at by her.
• A few days pass and you meet Geto and Gojo.
• Both men powerful, but one was more like you.
• You didn't cling to Geto, but your eyes lit up more than they did with anyone else when he's nearby.
• He was so cool to you. You showed him your diamonds and you saw his cursed spirit balls.
• Yet Geto ate his, and you stuck them in your skin.
• Gojo was fine, but Utahime didn't like him.
• Then a month passes and Toji is dead.
• You went to the morgue and just stared at his body.
• Your "friend."
• Your cut has long since healed, but you were unattended and there was a knife, so you reopened the wound and shoved the eye diamond in.
• You saw him standing there staring at you.
"Why'd you do that dumbass?" Toji asks as he tilts his head to the side. The hole in his body still there, but he's standing. You look at the body then up at Toji. "I don't know. I had a feeling I'd see you again." You shrug not fully wanting to admit to being sad he's dead. "Hey, I got a brat... His name is Megumi. Doesn't matter who he ends up with. Stick with him for me, okay brat?" Toji asks as you nod. "Don't forget to get strong." He says as he fades away.
• When you got home to Utahime you were yelled at for several hours for the cut on your cheek.
• As you got older you went to the Kyoto school.
• But you'd regularly visit Gojo if only to ignore him and hang out with Megumi instead as Utahime yelled at Gojo in the background.
• You met your fellow first years Mai, Miwa, and Mechamaru.
• And the second years Kamo, Todo, and Momo.
• Mai strangely clung to you. You gave her comfort in a way Maki did when she was younger. You promised as long as you were near her you wouldn't let the monsters hurt her.
• Miwa was always talking to you about Gojo and you'd just tell her something embarrassing about him. (Like how you scammed him really easily because you weaponized sweets.)
• Mechamaru is always on edge around you. Mostly because despite being human half the time you don't look it. Your limbs changing to match the many cursed spirit diamonds you've gathered over the last 9 of 10 years of your life.
• Kamo always pushes you to get stronger which you don't mind, but you do intentionally piss him off like you do Utahime.
• Todo keeps asking you for your type, and you give him a description. Whether it be man or woman you tell him exactly what you want. He's slightly impressed, but it's not brother status worthy. It's close though, so he helps you a lot.
• Momo gets creeped out by you too, but she likes dressing you up to be cute. She thinks when all those damn holes on your body are covered up you're cute! And she convinces the other girls to help her dress you up.
• Speaking of the holes on your body, you have one large hole on each arm that has others that go smaller and smaller until they reach your wrist.
• You have two slits under your eyes as well.
• You have holes on your legs and back mimicking the ones on your arms.
• Why? They hold diamonds. Ones that turn your body into a cursed spirit.
• It's always really painful, but it's worth it.
• Of course you met the first and second years of the Tokyo school.
• The other first years, Maki, Yuta, Inumaki, and Panda.
• The second years Hakari and Hoshi.
• Maki would ask about Mai indirectly to check in on her. You, being very direct, would outright say what you believed. Maki wasn't 100% on board, but you always treated her with extreme respect. (She reminded you of Toji.)
• Yuta panicked around you when you first met him, but he's gotten a lot more confident since then. You both bonded over your strange techniques, and you quite like Rika even if you tried to turn her into diamonds when you first met her.
• Inumaki was easy to understand after a while of being around him. You'd always lend a hand, or a mouth when you were with civilians or with Kamo.
• Panda liked you, and you liked Panda. He'd spin you around and throw you and you'd go back over and over again to repeat it.
• Hakari liked you. You had the fever of a gambler you'd crave more and more. He's watched you put a diamond in you can't control and when he asked you why you'd just say he made you feel like you could take the gamble.
• Kirara wasn't close with you, but you both bounced ideas for your techniques off each other.
• Then the year passes and you meet your first year!
• You liked Arata you'd poke fun at him all with that blank expression on your face, but he was a good guy. Which meant one thing. You wanted him to quit. To leave and go back to being normal. Good people died too much in your line of work.
• Speaking of you want Utahime to step down. To be a normal teacher of a normal highschool. To just leave it all and be normal. You could protect her if you needed. You just didn't wanna lose someone so... Weak.
• Then you met the Tokyo school first years!
• Megumi knew you as a strange older brother who's been in his life since Gojo took him in. You'd never tell Megumi, but you'd always look out for him because of his dad. To be fair now you do it because you like to harass him and just spend time with him.
• Nobara was mourning when you first met her even if she denied it. You helped her out and showed her some spots on the body of curses that were best to hit with nails. You were nice even if she couldn't tell what was going on behind a blank expression that matched Megumi's face.
• Then the Goodwill event came.
• Gojo gave you all little cute mummy keychains which you promptly put in your pocket.
• Then he opened the cart and there he was. A boy who felt more like a cursed spirit or object than a human.
• You were absolutely enthralled and so you step closer and touch his hand only to feel a finger getting bitten off.
• Yuji looks at you in horror as Sukuna munched on one of your fingers.
"Ah, Iori-san, two of my fingers were bitten off." You say calmly as turn to Utahime. "What are you, oh my god!" Utahime says as she walks closer and looks at your hand. "Ah, wait it's only one finger. Give me a second." You say as you turn back to Yuji.
• You smile at Yuji as you put the same finger that was bitten off in Sukuna's mouth.
"Eat it. Go on. Make it even you coward." You say to Sukuna as he crunches down in anger. He starts yelling about how ignorant you are.
• You hum and put two diamonds on your fingers causing them to change.
"I think I'm gonna like you." You say to Itadori with a smile.
A/N: This took so long and was such a fun concept. I usually write batfamily stuff, so sorry if it seems like I'm nervous. I am since I have no idea how toxic y'all are or aren't lol.
