a headcannon that nobody asked for! overprotective itoshi brothers
if there's one thing that sae and rin can at least get along and agree with, is that no one ever touches their baby sister aka you. like we're talking about no boys breathing within a 1 meter radius from wherever you're standing or they're getting it type of overprotective.
and if anyone tries to cross that border, well, get ready to pray for their sorry asses for even attempting to do such thing.
so when the infamous u20 vs blue lock match was happening, you bet your ass sae and rin (telepathically) were both "concerned" for your being knowing that they'll have to face the most dreading question one could ever ask the two brothers,
"who's that chick that has the same long under lashes like you?"
you were seated at the VIP area where all the rest of the teams families were also staying at. you noticed some had their player's respective jerseys on. you on the other hand, having brothers on both opposing teams, you could only do so much. you only had one balloon from each team in each hand.
hey, it's the thought that counts.
the first half of the match just ended and that means it was time for the half time. there, you took the opportunity to cheer for your two brothers, so they were aware of your presence.
"sae-nii! rin-nii! over here~♡" you wave
even if they were both on the opposite sides of the field, both sae and rin simultaneously looked up to find your voice
and of course that also means that their nosy teammates are also looking at your direction because, what do you mean there was another itoshi that they did not know about?
(both brothers purposely left out the vital information that they did in fact have a little sister because you know..)
"woah! who's that cute chick" otoya was the first to jump on rin. followed by karuso who also said the same thing
"rin, you have a little sister?" isagi joins in the little circle surrounding rin who looked like he was gonna bite somebody's head off.
"she's pretty" chigiri comments, also looking up at you. "long under lashes really run in the family~" bachira says in a singsong voice, waving at you
"everyone shut up!" rin barks, breaking away from the little circle that formed. by little i mean almost the entirety of the blue lock team (yes. including the bench warmers)
"rin-nii~ don't be mean" you yell from above, poking your tongue at him. rin gives you a "not the time' look that he usually gives you at home but to you it was fun to see rin so worked up because you know he's the one that gets verbal when it comes to you
there was a sense of satisfaction when you hear his team laughed and teased rin. choruses of:
"yeah rin-nii chan don't be mean to us~☆"
"just tell us her name, rin! we won't bother you again!"
"if i pass you the ball, would you give me her number?"
on the other side of the field, there was only one person sae has to look out for and that was no other than the man, the myth, the demon himself, shidou ryusei
when your familiar voice rang through sae's ears, you can only imagine what his face was. he clicks his tongue in annoyance and hesitantly looks up at your direction, wary that his teammates would also be looking with him
to his dismay, some were looking with him because who had the guts to call sae like that out in the open?
"she's hot isn't she, under lashes senpai~" he hears shidou tease behind him. sae reacts to this by giving him a good ol' wack on the head.
"that's my sister, you demon" sae spat, internally grimacing that shidou had those kind of thoughts about you. no, not on sae's watch. although, the realization only dawns upon sae that he just openly admitted that he had a sister
shidou somehow lived up to his insect nickname by jumping and zooming around sae in happiness or he says "i'm releasing dophamine~♡". while also screaming about how he now has dibs on you.
"you fucking demon. she's off limits"
sae may be shorter than shidou but damn, can he really threaten someone like it was nothing. shidou lowkey cowers in fear but he doesn't let that get to his head. in fact, he thinks this might be one hell of an opportunity to push the prodigy genius off the edge for once in his life
"if i score a hat trick, i'm getting her number. bet?" shidou proposes in a sing song voice. this agitates sae further. quickly shutting his offer with a simple, "hell no."
"then.. can i get yours instead?"
"if it means you backing away from my sister then i'll consider"

ITOSHI BROS FIND OUT THWIR SIS DATING A TEAM MEMBER THEY SPECIFICALLY HATE.
HER DATING ISAGI OR SHIDOU (IK SAE DOESNT REALLY HATE SHIDOU BUT STILL)
It's worse cause isagi or shidou won't even get scared of the brothers. They would just be cocky about it oml.
and the member they specifically hate is no other than the man, the myth, the demon himself, shidou ryusei!! ++ part two of this basically
you are actually genuinely surprised that your secret boyfriend, shidou has not outed himself that he was dating you, a literal itoshi, in secret
that is until one day that you decided to sneak shidou inside the house not knowing sae was home
“ryu! stop” you gasp playfully after you felt his hand grope your ass while you two were quietly tip toeing upstairs to your room
“you know you want it, angel” shidou coos, snickering to himself after watching your reaction.
when you both reach your bedroom, shidou did not waste a single second and crashed his lips with yours. wrapping arms around your torso, pulling you closer and closer. his hands were roaming around your body like an animal.
he guides you to your bed, he carefully lays you down and straddles you. shidou removes his shirt and throws it somewhere in your room.
shidou pulls away and looks at you like you were some prey. you whined, pulling his head close. shidou hovers over your neck, blowing on your sweet spot before sucking on it.
you let out a small mewl, clamping your legs together but shidou places his knee in between. shidou grunts, crashing his lips against yours once again til you hear the garage doors open and close
“fuck!” you and shidou curse. he jumps off of you as you wiped your lips with the back of your hand. you sit up and try to fix yourself from you and shidou’s little activity. shidou paces around your room trying to eavesdrop outside in case one of your brothers barge in your room (he’s praying they don’t)
“fuck, ryu! where are you gonna hide?!” you hushed, scared one of your brothers would hear you. shidou shrugs and sits on the foot of your bed,
“they won’t find me. i’ll just jump out your window if they come in” shidou wiggles his eyebrows, as if he was teasing you. you slap him before coming up with a plan to scout your house and try to keep your brothers away from your room as much as possible
“whatever, ryu. i’m gonna go come down to look who just came home. could be my parents”
“okay, angel. whatever you wanna do” shidou waves you off as he finds something else to entertain himself. you huff, kicking his butt playfully before going downstairs.
you waltz inside the kitchen to see rin who looked like he just got back from his gym sessions.
"what is that?" rin asks, pointing at a strange looking bruise that was on your neck.
you reached over to touch the spot rin was pointing at and immediately you had flashbacks on certain events that occurred the moments before.
"a mosquito bite" you lie, swatting his hand away as you scurry over to the fridge to get something to eat
rin raises a brow at your weird answer, "why is it on your neck?"
you turn around to look at him and shrugged. "how should i know? i'm not a mosquito"
you backed up from the kitchen only to bump into sae who looked like he just woke up from his daily afternoon nap. he hisses and basically snaps at you to watch where you were going before his eyes spot the same "mosquito bite" you lied about
"what the fuck is that a hickey?!" sae's eyes looked like they were about to pop out from his eye sockets. he grabs both of your shoulders to have a proper look on your neck
rin immediately runs in, also to inspect the weird looking bruise he saw earlier
"I KNEW IT! IT WAS A HICKEY" rin accuses, pointing yet another finger in front of your face.
"should i go find this mosquito and beat the shit out of him?" sae blurts out, stretching his limbs
"how do you even know what a hickey looks like?!" you exclaimed, trying to run away but of course rin comes in and blocks your way
and of course during your commotion, shidou must’ve accidentally knocked something down inside your room. you closed your eyes and face palmed that shidou just blew his cover. both brothers pause before looking at the direction of your room. both rin and sae make eye contact before bolting up the stairs to try and catch shidou who was inside your room
you let out a shriek as you tried to chase down your two athletic brothers up the stairs.
sae was the first one to get to your door. without hesitation, he yanks your door open (almost breaking it) and barges in. eyes scanning the room for a potential intruder aka your boyfriend that they now know off.
the window was open and all of you heard a loud thud outside and some bushes rustling. rin peeps his head out the window to see shidou running for his life, his shirt on hand
“I’LL SEE YOU ANOTHER TIME WHEN YOUR BROTHERS AREN’T HOME, BABE!” you hear shidou yell from the distance.
you may never not be able to leave your house without one of your brothers OR you will never be left home alone ever again after this

itoshi brothers reaction to their little sister wearing a different jersey and supporting someone else 😭
anon ur mind… should i make this into a series 😭 100 milestone special
can you imagine the reaction of both brothers when they see you lounging around the house with a jersey that’s not from their respective teams?
sae never misses the chance to give you a jersey from his matches. he always makes sures to get two of the same jerseys no matter what. sae would never admit this though. when he gives you his jerseys, he just tells you it’s an old one but it’s a lie. he has his own sitting in his luggage, gym bag, you name it, it’s there. he personally got one for you cause you were his sister after all
rin on the other hand is the same but he only gives you hand me downs such as the blue lock one. if rin grows out of a jersey, you bet that said jersey will end up in your hands
so just imagine the look on their faces when you’re lounging at the couch, wearing a jersey from a team they’re not even in on.
sae is visibly pissed. you can tell by the way his eyes are more narrowed than usual and has his infamous bitch face on that he only makes when there were press around him.
rin is not as pissed like sae but he’s just wondering who owns that jersey. he only gets mad when he tries to connect the dots or something and ended up assuming isagi or someone from blue lock gave it to you behind his back (he already had a talk with his blue lock mates that they should not breathe, touch, or be even in the vicinity as you when you’re around or they’re gonna get “it” from him)
both brothers sit at each side of you and you can tell the atmosphere in the living room has shifted. i mean, it’s not like you’re used to it at this point but, what gives bros?
sae scans you from the bottom to the top with a face you can’t quite pinpoint. was he mad? was he disgusted? what’s he thinking? you can’t tell. you turn your head to rin for some help but he had the same face on.
was there something on your face?
“if you guys are just gonna be breathing heavily next to me and not say a word then i’m just gonna leave” you raise a brow at your two (idiotic) brothers. to which they only reply with them clicking their tongues and some grumbles under their breaths.
sae was the first one to break the ice
“who’s jersey is that?” sae frowns. like a deep frown. was this mf really THAT petty over a jersey?
you looked down at the shirt you were wearing and it was from bastard münchen.
“oh, it’s bastard münchen merch. this is kaiser’s jersey if i’m not mistaken” you explain, even turning around to show sae the number on your back. when you return back to your original position, sae looked like you just dropped the biggest bomb on him and he didn’t like it one bit. he instantly gets all over your face, basically interrogating you on why you would waste the hard earned money he gave you to buy another jersey that isn’t from real madrid (hc that he gives you allowance 😋)
“why the fuck would you even buy from bastard münchen? is real madrid’s merchandise not enough? is the quality shit? hold on, i’m gonna have to tell the managers about this. just why y/n. WHY”
sae almost goes into a complete mental breakdown. over you wearing some team’s merch instead of his own team, real madrid
“and it had to be kaiser’s number too”
“what’s so bad with kaiser?”
sae doesn’t answer directly but continues to bitch about kaiser and bastard münchen specifically. mumbling about something you can’t quite understand
you look at your other brother, rin. just to like check if you two were looking at the same thing, sae literally pacing around the living room with his arms crossed and his hands rolled up into a fists but all you see is rin concentrating really hard that was outright sweating and you can see prominent veins on the sides of his head
“that damn isagi…” you hear rin murmur beside you. oh hell nah, not rin too.
“rin-nii..?”
“have you been talking to isagi? how do you even know about bastard münchen? does this mean you’ve been talking to isagi behind my back? why didn’t you buy pxg’s instead?”
another set of questions (more like interrogation) comes rolling in.
at this point you are already feeling like you’re going insane with your brothers acting like it was the end of the world.
“guys.. i literally watch blue lock tv. of course i fucking know about bastard münchen!” you curse
both brothers stop their idiocy and both turn to you with stern faces, together they go,
“NO FUCKING CURSING”

ITOSHI BROTHERS FINDING OUT THEIR LITTLE SIS/BRO LOST THEIR VIRGINITY (idk why i typed this all in caps lmao im sorry, also hi again my fav sae writer/stan)

helloo i just read ur itoshi brothers hc and I LOVE LOVE LOVE ITTTT the concept is so cute istg I NEED A PART 2 🫀
Tumblr media Tumblr media
i decided to merge both of these asks into one since they're kinda the same premise anyway so this will be a self insert of your own blue lock boy! so that'll mean (bl/p) = blue lock player! also pretty much rin centered 😘
honestly speaking, the only one who'll ever have a problem with you dating is rin tbh. i mean, sae would also bitch about you dating at your age but it's not the same kind of bitching like rin's (💀)
rin would 100% pop a vein vessel when he finds out you're dating one of his peers from blue lock. there's no debate to it. he will quite literally lose his shit.
because first of all, those little blue lock boys that are on rin's palm literally made a scouts honor (rin basically forced them tbh) that they will not be interact with you even if it meant life or death. second of all, i've said this multiple times but it's true, they're gonna get it from rin. he does not give a single fuck if they were teammates, on the same team, literally even if they were roommates with him. rin will absolutely "devour" and "kill" them on and off the field.
so the u-20 vs blue lock match comes rolling in. it currently halftime and all players (including rin) were taking a short break and drinking water while discussing with ego about their plan for the next half of the match.
on the corner of rin's eye, he notices a player walk up to the stands, near where the VIP's were seated. he was about to call them out for not listening to the upcoming game plan but instead he was met with you, his sister, his own blood relative, wiping the sweat off the player's face with a ridiculous smile on your face.
"y/n, what the fuck!" you hear someone complain. you looked up and look who's stomping on the way to you? that's right! it's rin! with his infamous scowl.
"rin-nii~ hi!" you chirped, waving your hand at him. rin stops and whips his head towards (bl/p), glaring at them with the nastiest look on rin's face you've ever seen
"what the fuck is this about, (bl/p)? do you have a deathwish or something?" rin starts to nag. a little too loud for your liking tbh. because all the other players (including u20 btw) are now looking at the commotion.
seeing you looking all lost and confused in between rin and a blue lock player sae has never even heard of, he decides to intervene.
"what's this about, y/n?" you hear sae ask, walking over to you, rin and your boyfriend.
"sae-nii! hi! rin is scaring my boyfriend" you pout, motioning your hands to your boyfriend and rin bickering. sae was about to open his mouth to say something before he whips your head at the speed of light the moment the word 'boyfriend' escaped your lips
you. had. a. boyfriend?
"what did you just say?" sae repeats, putting a hand on his ear as if that would change the shit you just said. sae immediately diverts his attention to your boyfriend and rin. your eyes widened at the realization the both of your brothers were (if not) about to team up for once in their life and quite literally devour your poor boyfriend.
but it seems like luck was with your boyfriend that day. the referees just blew their whistle, indicating it was time for the other half of the match just right before sae opened his mouth.
your boyfriend sighs in relief and jogs over to the rest of the blue lock team with rin in tow. but before rin and sae go back to their respective teams, they both turn around to face you and motioned the "i'm watching you" sign. rolling your eyes, you waved both of them off.
it’s gonna be one hell of an earful at your shared itoshi gc later

OVERPROTECTIVE ITOSHI BROS LORE LEMME CONTRIBUTE SOMETHING
"W-what are you doing here?" Rin's eyes widen in horror as he sees his teammate in your room. To which Rin's teammate replies that you just needed some help with homework. BUT HELPING WITH HOMEWORK IS SUPPOSED TO BE DONE WITH A DISTANCE, NOT BEING SO CLOSE TO ALMOST KISSING LMFAO
rin wouldn't just widen his eyes in horror, i'd honestly think he will deadass 100% explode. your lil boyfriend aka his teammate will never see the light of day. rin will pull a shidou and start swinging i fear. even swallows his pride to call sae over the phone to tattletale on you. next thing you know sae is already booking the next flight back home

i think it’d be funny if itoshi sis hated kaiser and the itoshi siblings would literally just start gossiping abt him (she has a kaiser hate page on twt)
you’ve never seen sae smile like that or the way his eyes instantly lit up and looked like he was brought back to life the moment you said “i don’t like kaiser” came out of your mouth
instantly tells you all the things sae doesn’t like about him. like he literally sits you down and forces you to listen (you obediently do bc ur also curious lol) and just babbles til your ears tear off. like this is genuinely the first time you guys have talked for so long
and rin just listens to you guys while occasionally telling his own opinions only to get shushed by sae bc “he doesn’t know what he’s talking about” and then continues on to talk shit

A little what if for protective Itoshi bros:
Their little sister decides to arrive to one of their games to bring them lunch because they forgot and she's worried about her nii-chans.
When she arrives, all the boys are shocked to see a pretty girl ask to talk to Rin and Sae and start bombarding her with questions and blocking her path. And little Itoshi, being the clueless dork she is, answers them politely but is starting to get uncomfortable with all the stares.
Que Rin and Sae teaming up to loom over the peasants who dare look at their precious baby sister with such lustful eyes (even when their just being nice lol).
When they ask her why she's here, she shows them the packed lunches she made for them and the Itoshi brothers are beyond grateful despite their cold gaze. Before she leaves, she kisses them both on the cheek, says she loves them and that she'll be cheering them on.
When she's gone, the bros start to have a snarky battle over who's the fave brother even as their eating. Meanwhile, their poor, unfortunate teammates look on in jealousy at their yummy lunches.
sae and rin get so mad when ur being bombarded with questions from both of their respective teams and lowkey you too because you have no time for chitchat
cue the infamous "what the fuck are you doing here?" from sae while rin is more like "what is it this time"
both brothers post on their social media accounts that you brought lunch but they dont caption that its from you aka their sis bc god forbid the press and the rest of the world will also be up in your business

Am I the only one imagining rin and sae's little sister making them super cute (and filling) bento lunches that look so aesthetically pleasing and tasty that any teammate who isn't teasing them is super jealous or tries to steal a bit of their bento? Hell, they probably take pictures to compare who's got the more attractive lunch.
it turns into a competition between sae and rin on who got the better lunch (it's literally the same shit packed) and they simultaneously post on instagram to try and one up the other

Itoshi brothers notice their lil sis always wearing that one jacket. They yelled at her to take that off and wash it ffs. One day Sae finds the jack laying around in the living room and thinks finally he can put it in the damn washing machine. But he takes a closer look at it and finds it too damn familiar. And he guessed right as his eye twitches when he sees Kaiser's initials.
omg sae doing the laundry when hes at home…… so true ‼️
if last time it was rin who lost his marbles this time it’s sae again because at first he thought the new gen world 11 tracksuit jacket lying around the couch was his until he caught a glimpse of the name at the back. embroidered onto the said tracksuit spelled out KAISER and not SAE. will 100% attempt to throw the tracksuit away but you caught him in the act of doing so 💀💀
when he gets back to spain or wherever the new gen 11 trains and shit you best believe sae will be up kaiser’s ass

Sae and Rin getting competitive when Lil Sis! Itoshi shows them affection. From feeding them to hugs to holding hands, these two will fight over it in silence as she remains oblivious or ignorant.
sistoshi knows but she just acts ignorant cs she sees the way the two brothers try to one up each other 💀
sae tends to spoil sistoshi with material gifts which is equivalent to a big hug while rin on the other hand spoils sistoshi with acts of service and words with affirmation telling her she’s doing a great job, etc. yet again earning the same thing which is a hug
in the end to win sistoshi’s affection, she comes up w a plan that the three of them should head out together and they should successfully return home after a long day WITHOUT a single argument between sistoshi or anything in general 💀
