YES MY BOY I LOVE THIS MAN HE IS LITERALLY CHAOTIC BIG BROTHER OR DUMBASS DAD MATERIAL!!

let’s say you were maybe nine when tengen decided he was gonna leave your clan

you were too young to be in a fucked up place like this, he can’t stand the idea of a lil girl like you dealing w this shit, especially since your guys’ dad and remaining brother were like

“wOmEN aRe For mAKiNg KidS”

he does not stan

absolutely not flamboyant

“c’mon kiddo it’s just us now”

he took you w him!!

tengen still teaches you how to fight but just like he tells his wives later on in life, prioritize yourself over all else

HIS WIVES!! LOVE YOU!!! VERY MUCH!!!!!

they better fuckin love you or he’s gonna be real mad

you are!! in the center of his world

even if he taught you how to fight he doesn’t want you in danger’s way

he wants you to grow up in the most normal way possible. lil child like you deserves the chance to be happy and have a sense of normalcy

but let’s say you eventually convince him to let you be a demon slayer

(it’s not that he isn’t supportive!! he makes it v v clear he doesn’t want to lose you, the only blood family he has left/considers family still. he wants you to do what you want to do but he’s hesitant when it comes to putting your life directly at risk)

but you ain’t givin up and tengen knows so he relents

he does his best to teach you the breath of sound!!

bc if you’re gonna be a demon slayer you gotta be the most flamboyant girl the world has ever seen

and he’s gonna fuckin make sure that comes true

you’re wearing earrings and rings just like him

he prolly loves spoiling you rotten bc the way you smile and cheer gives him life and he would have it absolutely no other way

protective as all fuck

like sweet jesus

please calm down

agatsuma better watch his fuckin neck or tengen’s gonna lop his head right off for treatin his baby sis like that!!!

your bro drinks women’s rights juice every meal of the day and expects everyone to do the same

he loves his wives!! and he loves you!!!

you’re more of a daughter at this point ngl and he’s your legal guardian but he’s still your big bro

DON’T BE FORMAL W HIM HE WILL BE UPSET

like. really really upset

tengen prides himself in being trusted by you and you feeling comfortable around him, that’s all he cares about

if you get hurt someone is gonna die

pinky promises.

✿ synopsis: it's been two weeks since learn to love, and megumi still hasn't opened up to oc gojo girlfriend or satoru yet. so oc gojo girlfriend decides to teach him something about promises.

✿ a/n: i have a soft spot for gojo being megumi's guardian. oc gojo girlfriend is trying so hard, little does she know, megumi actually really loves her already, he's just too shy to show it. also, oc gojo girlfriend comes from a big shot sorcerer family, and she has an older brother named touya (specifically because i love touya kinomoto from cardcaptor sakura) who is also a powerful jujutsu sorcerer. geto and the others make a tiny appearance!!! not proofread.

✿ reminder: if you want to imagine yourself in oc gojo girlfriend's character descriptions, please do! don't feel like you have to follow the oc gojo girlfriend's green eyes and long black hair.

it was dinner time at the dining hall for all the tokyo jujutsu high school students. while the men were cooking dinner (and by men, that meant all the men were watching nanami cook dinner), you and shoko spoke about the recent gossip that spread like wildfire across campus: you and satoru gojo becoming parents.

“so, gojo brought these kids to your room and basically said that he’s taking them in?” shoko repeated. 

“yeah, crazy right? as of two weeks ago, i'm a mother.” you said as you watched megumi and tsumiki in the corner of the kitchen, they were coloring with crayons.

“do you really think that you and gojo can be parental figures in their lives?” she questioned as you were still gazing over at them.

“satoru seems to think so. i didn’t think he’d make me a teen mom.” you joked.

as you watched the two young fushiguros, you wondered if you would be good enough to give them parental advice as they grow up in yours and satoru’s care. could satoru really raise megumi to be a jujutsu sorcerer? everyone knew that satoru gojo was the strongest, but could he raise a jujutsu sorcerer even if he wasn’t fully trained himself? satoru was still working on perfecting his own techniques like his long distance teleportation and his domain expansion. only you were second to him in laying out your domains.

who would give the birds and the bees talk to megumi? and who would be there for tsumiki when she starts to mature? when she gets her first period? that would be up to you to teach her about puberty and becoming a woman. god, satoru gojo couldn’t even talk about the reproductive system without giggling.

***********************************

“how does (y/n) feel about you taking the kids in?” suguru asked as he and satoru watched nanami flip over gyozas in the pan. 

“she didn’t take me seriously at first.” satoru replied to him. his mouth watering at the sight of the crispy gyozas. the oil in the pan danced along with the sitting gyozas.

“i mean... have you seen yourself? we can’t even take you seriously.”  nanami retorted.

satoru frowned, “thanks nanami...”

“(y/n) is kind. she would do anything to help.” haibara put in his two cents. he was a big fan of yours, it was because you were so nice to him and nanami when they joined jujutsu high. you were the one to show them around campus on their first day.

“haibara is right, (y/n) is the best. satoru is lucky to have her. i don’t know how she deals with him.” suguru laughed as he put his arm around satoru's shoulder, teasing him.

“she said she’d help, but that’s after i begged.” satoru grumbled. he hated to admit that he had to beg.

“you? beg?” nanami snorted. he flipped the last of the gyozas and put them on the shared plate. he turned back to the stove and stirred the soup that was boiling away.

“i told her the circumstances, it was up to her ultimately. i could've raised them myself.” satoru folded his arms in defense. he looked over at you and shoko and saw that you were watching the kids too.

***********************************

you and shoko got up to walk over to where megumi and tsumiki were coloring. “megumi? tsumiki?” you called their names. megumi continued to color and tsumiki looked over at you obediently. her smile could blind a country. she was such a happy child despite her situation.

“kids, this is shoko ieiri. she’s a second year like me and satoru. she’s studying to be a doctor, so if you guys get hurt, you’ll see shoko, okay?”

“hi kids.” shoko waved to the children. she was able to hold a steady conversation with tsumiki, but megumi continued to color and color and color. he didn’t pay anyone any mind.

“dinner’s ready!” haibara called out. 

“come on, let’s eat.” shoko grabbed tsumiki’s hand and guided her to the dining table. you were about to leave with them, but saw that megumi didn’t get up from the little table to join everyone.

“megumi, are you hungry?” you crouched down to ask him. he ignored you, like he had been doing for the past two weeks. you folded your arms in discontentment. how were you going to get through to this kid? his walls were up and you didn’t know how to bring them down. how could you let megumi know that you were there for him?

“megumi! let’s eat dinner!” tsumiki called out to him, but he just brushed her off. 

“i'm not hungry.” he said quietly.

“it’s okay, shoko, tsumiki, go ahead.” you shoo’d them away. you stood back up and let megumi color in peace. you made eye contact with satoru and frowned in defeat. you were worried about megumi. these past two weeks have been hard on you because you tried everything you could to get through to him, to build a relationship with him. as you sat at the dining table with everyone, you couldn’t work up an appetite. you poked at your gyoza and sipped at your soup.

“you not hungry, babe?” satoru asked, putting his arm around your shoulder as you softly sighed, he free hand rubbing your thigh. 

“not really. i'm worried about megumi. something seems to be bothering him.” satoru squeezed your hand and both of you looked over at megumi. he was still coloring. you saw him look over at the table a couple of times when tsumiki started to laugh while talking to shoko and haibara. 

you got up from the dining table as satoru’s arm fell from your shoulder to the back of your now empty chair. he watched you while you grabbed a small bowl of soup and a couple pieces of gyoza. you made your way back to the table where megumi was coloring.

“hi megumi, i brought you some food.” you greeted him. 

“i said i wasn't hungry.” megumi repeated himself again, avoiding all eye contact with you. 

“well, you haven’t eaten since breakfast, you must be hungry.” you frowned at him. 

“no, i'm not.” did you just hear some sass in his tone? you squinted at him.

“well, i'm not leaving until you eat your food.” you quipped back at him. if megumi fushiguro wanted to have a stubborn competition, he was going to have a stubborn competition. and you were the reigning queen of this (satoru would know).

you watched him color. he was drawing two dogs, a white one and a black one. you remembered your older brother, touya, teaching you about the zen’nin clan and the ten shadows technique. the first shikigami a ten shadows technique user could summon were the demon dogs. was megumi already seeing his shikigami?

“are those your dogs?” you asked him as you pointed at his drawing. of course, he just ignored you. “are they the demon dogs?” you digged deeper.

megumi stopped coloring and looked up at you, “what do you know about the demon dogs?”

“well, i know that it’s the first shikigami a ten shadows technique user can summon. they are used for many different things like tracking, fighting, or just being there by your side to keep you company.” you told him. megumi put down his crayons. it seems like you piqued his interest.

***********************************

“hmmm, it looks like she got the kid to stop coloring.” satoru announced, looking over at the table as he watched you and megumi. he felt a weird feeling inside. it was warm and fuzzy. his heart swelled watching you with megumi.

all the second years and first years looked over at the table to watch you and megumi as well.

***********************************

“can you tell me about the ten shadows?” megumi asked you quietly. 

“only if you eat your dinner.” you made him a deal, it was up to him to take it or not. megumi furrowed his brows as he slowly reached for the pair of chopsticks to pick up a piece of gyoza. you felt that you could continue telling him what you knew now that he started to eat. 

“there’s a specific hand sign that you have to do in order to summon any of the shikigami.” you explained. 

“do you know the hand signs for the dogs?” megumi asked, chewing his food. 

you smiled softly. “i don’t, but i know who does.” 

“who?” 

“satoru gojo does.” 

“oh, the creepy guy with the white hair and sunglasses?” megumi’s comment made you laugh out loud. that was the first time someone called satoru gojo creepy.

“he does give you the creeps, huh? me too.” you joked with him. megumi cracked a smile. 

“oh, did i just get a smile from the megumi fushiguro?” you feigned with shock. megumi started to grin, but he contained himself and ate some more gyoza and sipped at his soup.

“megumi... i know your father and mother left you and tsumiki...” you started to say, but megumi interrupted you. 

“and? everyone always leaves in the end anyways.”

you blinked in shock at how straightforward this 5 year old boy could be. you actually weren’t even sure if he was 5 anymore with that last comment of his. 

“well, satoru and i won’t. we’ll always be there for you and tsumiki. i promise. and (y/n) (l/n) never breaks her promises.” you held out your pinky to megumi in hopes that he’ll pinky promise you back. 

“what are you doing?” megumi looked at you confused. 

“have you ever done a pinky promise before?” you asked him. megumi shook his head. he hadn’t. you explained the story of a pinky promise to him, “people make pinky promises so that they don’t break their promise. if you break your promise, you have to chop off your pinky.”

“you’re going to chop off your pinky if you break your promise to me and tsumiki?” megumi asked you with skepticism. he seems like he’s had one too many promises broken in his lifetime.

“yes, and satoru will too.” you answered back. satoru would understand if you spoke for him. he softly intertwined his pinky with yours and you kissed your thumb to seal the deal. megumi didn't follow you on the kiss back though. it was okay, you'll get him to do it next time.

“do you and that creep pinky promise on stuff too?” megumi wondered. 

you smiled at him, “all the time.”

“on what?”

“well, satoru pinky promised me that he will be the strongest jujutsu sorcerer so that he can protect me.” you told megumi. one day, satoru would have to tell him the story about megumi's own father and how satoru’s near-death fight with toji made him have an epiphany about his own powers.

you looked over at satoru. he was watching you and megumi. he waved when you made eye contact with him. you winked at him and he blew you a kiss. megumi’s eyes wandered to him as well.

“so he’s the strongest?” he asked with uncertainty. he couldn't believe that satoru gojo was the strongest. megumi thought he looked like a derp, especially with the lack of tact he had when he first approached him and tsumiki. why couldn't you have been the one to find them instead?

“yes, he is,” you smiled brightly at your man, “and he’ll be your sensei when you attend jujutsu high school.” you thought about the conversation you had with satoru about him becoming a teacher once he finishes his third year. would megumi be okay with him being the one to teach him how to handle cursed energy and how to fight?

“are you strong too, (y/n)?” megumi questioned you.

“i'm the second strongest,” you looked at him intently with a promise, “and i will protect you and tsumiki, just like satoru will.”

“why did he pinky promise that to you?” megumi changed the subject as he started to blush. he wondered why satoru promised to protect you if you could protect yourself. 

“well, megumi, satoru is something you call a boyfriend to me. he loves me. and, well, you protect the people you love.”

“he was talking about you when he picked us up. he said you were his girlfriend. is that the same thing as a boyfriend?” 

“yes it is,” you said laughing. kids were so damn cute with their comments, “you might be too young to understand, but maybe when you get bigger, you’ll find a someone you love and you can be a boyfriend too.”

megumi ended up finishing his food. (y/n) 1: megumi 0. you had won the stubborn competition. he took the empty soup bowl and put it in front of you.

“can i have more soup... please?”

EXTRA:

the kids were sleeping in your room as you spent the night in satoru’s dorm room. this was how it had been for the past two weeks.

you climbed into bed as your boyfriend watched you. you sat closely next to him. he was expecting you to tell him the juicy gossip of what happened at dinner with megumi. after giving him a brief run down, he sighed.

“so, megumi is already seeing his demon dogs?” you scratched at the back of his undercut and tilted your head at him. 

“yes, baby, and you’re gonna have to teach him how to use them. i told him you know the hand symbols.”

“that’s fine, we can do that. the demon dogs are loyal and loving according to my sources. they would be good to have by his side.” satoru closed his eyes and sighed in bliss, he loved when you scratched his undercut. you stopped scratching as he hugged you close. 

“satoru... are you going to tell megumi about his father?” you softly asked.

“you know, i tried telling him when i found him, but that little shit just cut me off. i told him that if he ever wanted to know about his dad, he can ask me any time.”

“you promise you’ll tell him the whole story?”

satoru intertwined his pinky with yours and kissed you firmly on the lips. 

“i pinky promise.”

I hate how they portray allmight as a father

in EVERY all might x daughter fanfic i've ever read, all might almost always neglects his daughter and it's almost always angst no fluff and i don't like that, I mean if you like it, sure go head and read it but I think all might would never do that. if anything, all might would desperately try to include her in everything. izuku's training?you're helping him bandage the mf up. hero galas? a date? nah man, hes taking you only to show you off. even when you're a child, he will attend all your school events, serve tea at all your princess tea parties, even when he's tired he will at least make sure to read you a bedtime story. all might once mentioned seeing nana shimura as a mother and I think he would try to be an equally if not better parent then her. wanting to take care of you and prove himself not only a worthy successor and hero but also as a worthy father.

Shigaraki: "What the he'll was that?" "My sneeze." "Your sneeze? Sounds like a cat!" Is actually hiding the fact it sounded cute.

Aizawa: "I swear, you sneeze one more time while I'm napping, I'll tie you to the couch as punishment."

Mic: "Oh cool, you sneeze like me!"

Dabi: "You done being loud, babe?"

Twice: "I think I lost a clone in the earthquake."

Mr. Compress: "You alright? That sounded like it hurt."

Spinner: "Ah, I better calm the rupture you caused."

Shigaraki: "Do that again and I swear you'll regret it."

Overhaul: "That it? I'm expecting the tsunami to come ruin the base soon."

Hawks: He accidentally shot you with some of his feathers out of instinct (which he kept apologizing about)

Natsuo: "Hey, we have the same sneeze! But I think you're a hack of a lot louder."

Endeavor: You have been thrown out of his office on more than one occasion, now only getting a look when he sees you start up.

Fatgum: "Welp, there goes Tamaki out the door from your noise."

Sir Nighteye: "That it? I swear a train just hit the building."

The eardrum blower (You go to sneeze and plug your nose at the last second, how you haven't blown your eardrums is amazing):

All-Might: He was immediately concerned for yoyr well being, even after you tried to console him.

Aizawa: "Right, now sneeze like a normal person." "That was normal." "No, that wasn't normal, that was you asking for your eardrums to blow."

Mic: "Doesn't that hurt, babe?"

Dabi: "You trying to communicate with the dead?" "What kind of a joke is that?" "One that says stop doing it."

Twice: He had to stop asking after having multiple clones killed in a rage after having upset you.

Mr. Compress: "My love, doesn't that hurt?"

Spinner: "I would cut that out now."

Kurogiri: "I will send you into another room if you start to sneeze like that again."

Shigaraki: "I'm worried now. When did this start?"

Overhaul: "As long as you're not destroying my office with that sneeze it's fine."

Hawks: "Baby! Don't sneeze like that!"

Natsuo: "You're annoying, you know?"

Endeavor: You were relieved when he ignored you, until you were constantly being forced to sneeze normally.

Fatgum: "Dear, don't sneeze that way."

Sir Nighteye: "I will count to ten and you better have an explanation on why you're trying to blow your eardrums.
