#iwaoi headcanons

[breadsoup00]

Iwaoi headcanons because I have brainrot <3

Featuring: individual Oikawa headcanons because I think about him way to much

Btw transmasc oikawa and greyace Iwaizumi because I’m projecting

Iwaoi

Movie night at least once every week

It’s also a must that they stay at each others house at least once every two weeks

Iwaizumi definitely helps Oikawa with binding

They’re each others lock screen. Not a picture of both of them together, but just the other individually

They’ve definitely been to a pride parade because Oikawa dragged Iwaizumi there

Nobody actually thinks they’re dating because they’ve always acted like a couple. Once they got together nothing really changed except maybe they were slightly more touchy

Iwaizumi is whipped. Prove me wrong.

then again so is Oikawa

When Oikawa came out as trans (he was around 14) to Iwaizumi the first thing iwa did was offer to help pick out a haircut for when he got to cut it

and also go clothes shopping with him tk help him pick out new clothes

Oikawa is literally the BEST at supporting Iwaizumi being greyace and the day he complains about it is the day the world ends. Literally he will fight someone on the spot if they say anything about it. He does everything he can to make Iwa comfortable with it

Oikawa

He/they. Let me have this please. HE. FUCKING. THEY.

Wants top surgery but doesn’t want to stop playing volleyball even for a little bit to get it so. A binder has to do

I just think he likes reading. Idk why. He’s a little nerdy and I love him for it.

But srsly that concept is so cute to me. Like at school he’s Mr Bigshot with fangirls and shit but at home he likes to read lord of the rings and yeah he’s a little bit too involved with it

He paints his nails a lot but tbh nobody ever really notices because it’s never very bright, just neutral colors

He owns two cats and their names are Murphy and Pippin

has a bunch of those scented wall plugs from bath and body works

he likes NASA, like, a lot

[raisunomii]

Bokuto kuroo and tsukishima live by the phrase “happy wife happy life” which is why their relationships r fully functioning. Oikawa kageyama and suga live by the phrase “fuck you im right” which is why their relationships fall apart every 3 days.

[kings-highway]

absolutely dumbass behaviour I think haikyuu ships would exhibit on days when there's no braincell to share

Daisuga: Daichi forgets the word for something and stands there snapping his fingers and thinking up synonyms and "sounds like" and various prompts to try and remember and Suga's guesses just keep getting more inaccurate and unhelpful

Iwaoi: Oikawa falls down icy steps in the winter and in his excitement to go make fun of him Iwaizumi falls down the same steps and ends up right beside him.

Ushiten: Tendou and Ushijima decided to cook dinner together and are not able explain how they got from point A to point "the oven is on fire."

Asanoya: They both forget to bring money when they go out to eat. They offer to work it off and the restaurant manager has to explain to them thats absolutely not how it works outside of TV.

Tsukkiyama: Tsukishima makes a statement that someone else fact checks and finds out is incorrect - both Tsukki and Yamaguchi then double down with 100% conviction that no, actually, Tsukki is right.

I was going to include Kagehina in this but honestly theyve never had even one braincell between them so everything I wrote just sounded like descriptions of canon.

Streets are saying Haikyuu Time Skip is being animated!!!!! I am afraid of the person I'm gonna become if it happens, you better hide Mr Onigiri Miya, EJP Middle Blocker Suna Rintarou, Argentina official setter Oikawa Tooru, Brazil Hinata Shoyou and those MSBY idiots or respectfully I am omw :)

Iwaoi Childhood ✏

[eurydicees]

i think iwaizumi is like. ok so he comes off as cool and athletic and smart and popular and, yk, to a degree, he totally is! he’s incredible at volleyball and he gets decent grades and he’s a good friend and overall well-liked by the general seijoh population.

ALSO at the same time he is like. the lamest popular guy in the world.

this is a title that oikawa has given him and the part that iwaizumi protests is not “lame” but “popular.” some points that oikawa makes, when talking to iwaizumi about how much of a normal average deeply Just A Guy iwaizumi is:

iwaizumi’s favorite activity is, first and foremost, volleyball; and second, it’s “spend time watching d-rated martial arts movies with my best friend.”

i appreciate it and love this, oikawa says, obviously, but you do have other things you can do with your time. do you know that. it doesn’t seem like you know that.

he’s popular, he has other friends, he could have his pick of girlfriends, and he chooses to instead monopolize oikawa’s time through varying methods of aggression and/or affection.

why do you not have a girlfriend yet, oikawa asks. i’m too busy keeping you in line, iwaizumi says. to which oikawa replies, you suck at being popular, iwa.

people think he’s cool because he likes the outdoors, likes going on hikes with his free time, excels at every athletic task, etc etc.

what they do not know is that he likes going on hikes to look at the changing leaves and his favorite way to interact with nature is like his fucking rock collection or some shit.

do they have names, oikawa asks, teasing. shut the fuck up, iwaizumi says. then, fucking obviously they have names.

he’s not scared of bugs, girls whisper when he passes in the hallways. he saved me from a spider one time, they say, and oikawa claims they swoon.

and like, oikawa HAS to laugh because this is the same boy who tried to keep a tank of beetles he collected from the park and cried hysterically both first when they all escaped, and second when his mother yelled at him for ten minutes about the five she found in the sugar jar. he was fourteen.

“he’s so smart,” someone says admiringly when iwaizumi helps them a bit with their class work. oikawa is rolling his damn eyes because iwaizumi is smart, sure, he’s doing fine in school, but he’s evidently not smart enough to calculate the risk/reward of a monetary bet on how many pork buns he can fit in his mouth. more than 8 gets him 1000 yen. less than 8 makes him lose 1500.

what the fuck was he thinking, oikawa is forced to ask, first when he nearly has to perform the heimlich maneuver and later when he buys iwaizumi a consolation bottle of water. what the fuck.

people think he’s mysterious and stoic and kind of darkly intriguing because he doesn’t necessarily laugh a lot while he’s in class and focused, and while he’s friendly with everyone, he still sticks pretty close to his little group.

oikawa cannot believe that anyone could ever think this because iwaizumi gets home after school and does not shut the fuck up. and he’s so easy to make laugh. and his every expression is so easy to read.

how could you possibly have anyone convinced that you are cool and mysterious, oikawa asks. how the fuck did you do that.

iwaizumi is forced to shrug. he doesn’t really have an answer. people just kind of make their own assumptions about him no matter what he does. doesn’t matter anyways. oikawa might be the only one who seems to truly get him, but he’s okay with that. if it had be one person, he’s glad it’s someone he loves.

and now what the fuck is oikawa supposed to do with that.

(push him down on the bed and kiss him, oikawa finds, seems to be the right answer.)

[iwaoiness]

In the Argentine volleyball team, arriving late for training comes with the Blanco's famous penalty of thirty-three laps around the block, and captain Javier's fifteen-minute reprimand. Oikawa has only been late on rare occasions, yet even his most charming flutter of eyelashes couldn't exempt him from the punishment. He endured it, unfortunately accompanied by the teasing of Matias and Bruno—those two, inexplicably, are the only ones who are punctual alongside the captain.

However, that day, when Oikawa arrives ten minutes late at one of the Olympic Village gymnasiums, almost out of breath, his hair disheveled and still wet from the quickest shower he has had in his thirty years, he doesn't hear Javier's ché, boludo tardón that always starts his reprimands, nor does he hear Blanco loudly instructing Tomás to get ready with the stopwatch and the punishment sheet.

That day, everyone stares at him with wide, blinking eyes. The ball Bruno was holding slips from his grasp, the sound of its bounce being the only thing breaking the sepulchral silence.

Oikawa frowns, tilting his head slightly.

"What?"

"Hermano," Matias arches an eyebrow with genuine curiosity, though his eyes sparkle with amusement, putting Oikawa on high alert "since when do you play for the Japanese national team?"

This further confuses Tooru, who blinks.

"The hell are you talking about, boludo?"

The libero points to his shirt and Oikawa looks down.

Oh.

He's not wearing his favorite blue training shirt, but a slightly baggy black one at his shoulders, with the Japanese flag stitched on it at his heart.

And then he remembers this morning. How they woke up late, almost stumbling because neither of the two damn alarms went off. How they rushed to the shower, too small for two tall and strong adults. How Tooru had a fit of giggles when Hajime mistook the cherry lube for his after-shave lotion. How they quickly got dressed in the first things they grabbed, barely glancing at their clothes, before kissing, wishing each other a good day, and running off to their respective teams.

Oh, la concha de la lora.

Oikawa's eyes widen comically, and he ignores the tug on his neck as he quickly raises his head. Feeling the heat boiling on his face, he now meets the playful gazes of his teammates—even Blanco coughs to hide his smile.

"This has a completely logical explanation!" he stammers, glaring at Matias as his devilish grin widens.

"Really? And that logic is tall, dark skinned, and part of Japan's technical team, Toto?"

But when Tooru, his face now completely red, opens his mouth to protest, a solid knocks on the door interrupts.

Everyone turns to look, and Oikawa sees Iwa-chan standing in the doorway, just as embarrassed—if not more so—than him. Instead of his regulation black shirt, he’s wearing Oikawa's blue one, tight around his torso, with the Argentine flag in the center.

"Sorry to interrupt," he apologizes with his accented Spanish. "Can I borrow Tooru for a second?"

"All yours, Hajime!" Bruno chimes in, nudging Tooru forward playfully, sticking his tongue out as the setter glares daggers at him.

"But don't keep him out too long. The penalty waits him" José Blanco requests, widening his smile as Hajime nods firmly before taking Tooru's hand and pulling him outside, ignoring his childish protest.

i love them with my whole heart

iwaoi, but's it's iwaizumi who had always wanted to leave japan. he found his every day life in miyagi stifling. he hated seeing the same classmates over and over again with their disagreeable opinions and close-minded worldviews, hated the way the people in his neighborhood all knew each other and their business, hated the way it rained and hated the way the sun rose every single day. he hated the very idea of staying in miyagi more than he had to.

he talked to oikawa about this regularly, ever since they could form thoughts that ventured outside of their little realm in japan. first, he told oikawa he'd move out of miyagi. he'd find an apartment in tokyo, or a job as a farmhand in hokkaido, or anywhere else that isn't miyagi and the life he's had to grow up in. then, as he got older, he went a step further.

china, he'd mumble oikawa during the first class of the day in middle school.

the phillippines, he'd shout at oikawa while peppering a volleyball.

somewhere further, he'd finally admitted to oikawa while walking home from a late-night home court game, his gaze trained on the ground with the most vulnerability he'd shown in years. like america. i've applied to a college in america.

oikawa had laughed at him on most times. iwaizumi knew oikawa liked life in miyagi; he got along with his classmates fine, girls liked him, he loved his family and their neighborhood, loved the sunrise and the rain. iwaizumi knew this because oikawa had always disagreed with him on those subjects.

but liking life wasn't enough when oikawa's goals were set further than what he would be constrained to at home. loving japan wasn't enough when japan didn't love him.

argentina, oikawa had whispered, miserable, to him for the first time near the end of their first year in high school. he'd seen kageyama around. he'd seen the way his serves had gotten better and better and better.

their planes left mere weeks from each other. oikawa first, to argentina, with tears in his eyes and a sharp call to not be stranger. iwaizumi left second, wishing his family a farewell with his heart full to finally leave.

iwaizumi had liked california enough. he was entertained, if not occasionally confused, by the manner of young adult americans. he had thought, originally, that he wouldn't miss japan. maybe he'd miss his family and the two friends he'd left, but nothing else. he thought the pang in his chest when his american roommate and newfound friends went out for a chicken wing restaurant and not onigiri, when they spoke exclusively english (sometimes spanish) and not japanese, when there were beds and air mattresses and not futons, that he was missing familiarity, is all. he only missed not feeling out of place.

oikawa had shared with him, over their many calls, his own struggles with homesickness. but, oikawa had told him over grainy Facetime, my team has done everything to make me feel at home. spanish isn't as hard as i thought it'd be! i'm going to make this work. even if i miss you and japan. i just... i need this. i need argentina.

both he and oikawa managed to make it home for christmas after only a few months into their respective journeys into the americas. they arrived at different times, though, so iwaizumi made the trip home from tokyo alone. he took two trains, then a taxi closer to his house. he saw the billboards in his own language. he watched people that looked like himself. they went to restraunts with onigiri. their seating would be chabudai and not high tables and booths. he saw familiar streets and familiar faces in his neighborhood.

he came to his house, where he knew exactly where the patch of grass his childhood cat was buried in the backyard. he could see phantoms of himself riding his bike up and down the road. he could see where he caught butterflies, where oikawa chased him with a handful of worms.

he came home, and his family was waiting for him. it all rushed over him, when he saw them again. all the anxiety of not being able to get to them fast if they got into an accident. constantly wondering what he'd be doing if he was in japan and not at uc-irvine. thinking about how much he preferred his home culture to the strangeness of the united states.

he met with oikawa next, who regaled him on his adventures in argentina as if they hadn't talked nearly everyday since their planes took them away from home.

i'm going to stay, oikawa told him during a late evening stroll after dinner, his eyes alight with happiness and success. i love it in argentina. it's everything i want and need.

iwaizumi was happy for him. but, iwaizumi knew he would not be content doing the same.

i'm coming back home after i get my bachelor's, he told oikawa after a second's pause, letting the coldness of the evening wash over him, watching the sun set in the way he'd spent hating his entire life. america is nice, but japan is where i'm meant to be.

he found that he didn't mind the rain when he was no longer seventeen and hating his classmates. he didn't mind staring out the window of the house he grew up in when he wasn't sixteen and desperate to leave. he'd been to the other side of the fence, and the grass simply wasn't any greener.

and he knew he'd be okay with that, eventually, even if a part of him wondered if he was giving up. even if that part of him wanted to riot and rage and scream at the idea of staying in the place he'd always told everyone he'd leave.

oikawa looked at him, then, with his eyes still bright but shining with a different kind of light. and that's perfectly fine, oikawa said to him, his voice low and earnest.

there was not a hint of condescension. nothing that said, you gave up. you are worth nothing. you will be nothing. oikawa meant it when he said that it was fine that leaving wasn't all iwaizumi had chalked it up to be. his tone said, in every way, nothing has changed. you will be just as good here as you would be anywhere else. you have not given up. there is nothing wrong with letting yourself be happy.

somehow, that was more reassuring than any of the faux comforts he'd been trying to console himself with.

HC Brazil OiHina scribbles (platonic)

Hinata is a SUCKER for dance battles every time he gets into one oikawa has to drag him out.

They make picnics at the beach but it always ends up with them running around playing tag or chasing the objects that air took away.

They love watching the sunset together.

Oikawa is obsessed with hinata’s freckled thighs and hands, whenever he was stressed, he fidgets with hinata’s hand and counts the freckles.

Whenever Hinata and Oikawa get into fights, they’d unconsciously switch languages and laugh it off. (The only ever close to serious “fight” they had was when oikawa broke no contact with his toxic ex of Argentina)

Hinata almost burned off oikawa’s hair by accident (he wanted to light an incense).

6am morning runs, hinata wears shorts and a shirt oikawa got him (blue) and Oikawa wears sweatpants and a black muscle fit shirt.

Whenever something happens, they are the first ones to tell eachother, example: when tsukishima texted hinata back, flirting, Hinata freaked out he called oikawa (2am) screaming and accidentally woke up his own neighbors.

my haikyuu ship headcanons (halloween edition)

Kagehina

They fight over everything, and halloween was no exception. Kageyama wanted to go as a baseball player and a referee. Hinata wanted to go as Ariel and Prince Eric. Guess who won.

IwaOi

Iwazumi didn’t really care what they went as, he didn’t really have a ton of excitement when it came to holiday stuff. Oikawa on the other hand, was all in. He put up decorations, bought candy for trick-or-treaters, and made their costumes. They went as Ken and Barbie.

DaiSuga

Both of them are like corny parents during the holidays. They both get excited and they encourage everyone to dress up. They put up decorations and watch movies with the team, although some are more compliant than others. (looking at you, tsukki) They went as a sailor and a mermaid.

Bokuaka

Akashi really, *really* didn’t want to dress up. Bokuto did not care. Bokuto went as Lloyd from ninjago, akashi went as ‘himself in a scarf’.

KuroKen

Kenma surprisingly didn’t mind dressing up. Kuroo was thrilled when he learned this. The two have a tradition of going to spirit halloween and laughing at the dumb costumes every year. They both went as cats. (obviously)

UshiTen

Tendou really is in his element during halloween. Ushijima just does whatever makes tendou happy. The two of them sit around in their room the week before, showing each other costumes ideas. (well, tendou shows ushijima costumes. ushijima shows tendou memes from 2017 and Tendou pretends to laugh) They went as a doctor and a nurse.

requests are always open!

[raisunomii]

Iwaizumi Hajime eats a centipede on a dare yes he chops the pincers off first. Hanamaki dared him during a sleepover it was 1am. Hajime spent 3 hours in the backyard looking for a centipede under rocks Matsukawa found it. Oikawa held the flashlight. Iwaizumi eats it live it’s not that he wants to do this. He throws up afterward. It’s just that his friends are pricks who chant until he eats the centipede. He gargles with mouthwash not one not two but three times. Matsukawa laughs so hard he cries. Oikawa chokes.

[kings-highway]

some safe-for-work headcanons regarding how they might of gone about having sex for the first time for some of my favouritr haikyuu ships:

daisuga: look you know these bitches had it scheduled. not like a meticulous planned thing, but it was definitely something they knew was going to happen in advance. Like they talked about it, agreed they both wanted it, and then 3 weeks later Suga's parents go away for the weekend and they know like a solid week in advance that their "hang out" on Saturday evening is basically exclusively so they can have sex. They're very prepared. This also probably makes that week of training super annoying for the team bc they cant figure out why their captains are being SO overly giggly like you are seventeen/eighteen year old men wtf is going on.

iwaoi: i've always thought they were probably way more nervous than any of their friends assumed and definitely did not have sex as early as people thought. like mattsun and makki both constantly tease them in a way that insinuates they're actively having sex but they probably didnt actually do it until like... the last few months of high school. They were both just nervous! Iwa was very afraid of rushing things and doing it "wrong," and Oikawa wasnt even sure what doing it "right" would be so they had like 6 false-starts before they actually managed it.

ushiten: dorm living is not condusive to intimacy so when for the first time in like 8 months since they started dating that they have a confirmed evening with a locked dorm alone they end up making out for just a crazy amount of time. Tendou is too nervous to actually move anything forward because he's too anxious over the possibility of rejection but he keeps making these weird half-insinuations like "haha I cant believe nobody's going to be back for another four hours... we could do anything and get away with it... isnt that so funny... like nobody would know if we were making out or having sex or just reading a book... haha... isnt that crazy... me and you..." and he's all weird and twitchy about it until Ushijima tells him he doesn't think the idea of them having sex is crazy at all and then it is on immediately.

kuroken: highkey, kuroo probably lays out like a whole romantic, corny ass evening with candles and rose petals and is prepared to have a whole long conversation about being "ready" and Kenma just sort of rolls his eyes and is like "have you finished talking? this is Too Much. I need you to understand this is Too Much. Oh my god I love you but WOW." (it works anyway and Kenma is sufficient wooed).

tsukkiyama: this one might be a little out there but I genuinely think they're the most likely to have it happen by accident, or in a spontaneous moment of opportunity. Like they both intend to just take advantage of the empty house with only a bit of making out and then suddenly they're losing their clothes and it's like "we'll have a conversation about it tomorrow, im sure."

kagehina: okay this one is more stupid but I imagine after they've been dating a while Hinata is like "you know what, im ready to take the next step" but Kageyama cannot read ppl so Hinata's somewhat obvious attempts at seduction go entirely over his head, and Hinata is getting increasingly frustrated and dramatic and trying really really hard to get Kageyama to realize what he wants and it ends up causing a fight between them because Kageyama thinks Hinata is being weird and Hinata thinks Kageyama is being intentionally distant and eventually Kageyama blows up and is like "Oh my god if you want to break up or something just say so!!!" and Hinata is like "Oh my GOD I dont want to break up with you I want to have sex with you!!!" and of course that shuts everyone up and unfortunately Yachi is probably also there and wants to die.

[miyasstan]

This Oikawa manga panel has my heart and soul, because his petty pride is truly fantastic, even though we knew him as a monster setter, he never went to nationals so leaving his country as an unknown player to pursue his own path and coming back with a team who realizes his potential, he took everyone by a storm and this is what I live for. ONE OF THE MOST SATISFYING ENDINGS IN THE HISTORY, FURUDATE I LOVE YOU FOR GIVING US OIKAWA, HAPPY BIRTHDAY TO THE GREAT KING <3

(I LOVE HIM, I LOVE HIM, I LOVE HIM 😭)

[touchlikethesun]

how i think different hq couples get engaged

kageyama and hinata are dating and living together for over a decade before they get engaged. there's just always something more pressing going on - usually their pro-volleyball careers - and they're both just so content with how their relationship is, marriage just seems kind of like an unnecessary hassle and a logistical nightmare that neither of them want to deal with. once they reach their 30s though, and they've both settled a bit more into their careers, i can see one of them casually proposing one day - they don't even have rings - because at this point, they both know they are going to spend the rest of their lives together, why not make mrs. hinata happy and make it official. plus, a wedding is an excuse to get together with all their friends again. when they buy their rings, they buy chains at the same time so they can still wear their rings on the court.

tsukishima and yamaguchi get engaged a lot earlier than kghn, i think they get engaged a year after they both graduate from undergrad. tsukki bought yams' engagement ring in their second year at uni after saving up basically since they got together in high school, but he waited to propose until after they lived and worked "in the real world," just in case yamaguchi found someone better or if their relationship changed when they didn't have school as an excuse to see each other all the time (kei eventually admits this to tadashi years down the line and tadashi scolds him - the efficacy being undercut by the kisses he gives kei at the same time - for ever thinking their relationship was so fragile). obviously yamaguchi was over the moon when tsukki proposed, and takes to calling him "his fiance" at every chance he gets. they wait to actually have a wedding until after tsukki has finished his masters, and they've both started working, so that they can actually enjoy the event with as little stress as possible

iwaizumi and oikawa get engaged around their mid-20s as well. i think oikawa is the kind of person that has had their whole life planned out in a scrapbook since they were 10, and he knows exactly when and how he planned to propose to iwa, so when iwaizumi beat him to the punch - an evening complete with a romantic dinner in a jazz cafe that iwa scouted for the occasion, roses, and a walk to the playground where they first met where upon iwa finally got down on one knee - tooru was so shocked and generally overcome with emotion that he burst into tears and forgot to say yes until hours later, when iwaizumi asked him again after many kisses and sweet words. ofc, after the shock has worn off, Oikawa Tooru's Dream Wedding Plans are back on, and iwa lets him take over planning the most elaborate and expensive wedding japan has ever seen

(for my bkak headcanon see this post i made a few days ago lol)
