Headcanons

❥ Warning: Haikyuu (Romantic) Rarepair

❥ Finished: April 19, 2023

❥ Kae's Notes: I have no idea what has been going on with me lately with writing, but we’re in a love/hate relationship right now- So, take some Kogayamagoshi headcanons, featuring aroace Tsukishima. Please no hate!! Just trying to have some fun. This is my OTP poly ship, it makes me giddy anytime I think about it, AND THIS SHIP NEEDS MORE LOVE AND CONTENT!!! Please see my Navi for more info♡

HOW THEY MET

Well, it started with Koganegawa and Tadashi meeting during the practice match between Karasuno and Date Tech (during S4 of anime). Y’know, when Kogane said “Tsukki!!” and Yams got all bent out of shape? Well, Tadashi had a crush on Tsukkishima for the longest time, and when he found out that he had competition when it came to the salty blond’s heart? Kanji unknowingly became more than just rivals on the court. Although, much to their embarrassment, Tadashi found out months later when Kei came out to him as Aroace. Automatically he felt guilty for being a jerk to Kogane, so he asked Tsukki for his number to apologize to him. In true Kanji fashion, he didn’t even realize and explained he lost feelings for the blond and was talking to someone named Goshiki. So, they became friends!! Yamaguchi and Goshiki then met through Kanji, and while things were a bit tense, they soon blossomed into the trio no one knew they needed. ♡

IN THE BEGINNING OF THEM ALL DATING around the first few weeks, Tsutomu didn’t know that they were dating, just thinking they were all hanging out and stuff. When she found out, she was super embarrassed for not knowing. To make her feel better, Kanji hugged her and refused to let her go, except when Tadashi wanted to give her little kisses.

THEY ALL HEAVILY STAN Lady Gaga and Halestorm. They all flipped out when Halestorm did a cover of Bad Romance

TSUTOMU HAS A HARD TIME expressing her love to her boyfriends, so she shows her love by actions, a.k.a. doing things to make Kanji and Tadashi’s life easier and happier. She does her boyfriend’s chores when their tired so they don’t have to, or make them their favorites drinks after a long day. And to say I love you? Buys them their favorite flowers.

POST-TIMESKIP Yamaguchi always arrives home before their partners, but can always assume Goshiki will be home soon after. So, before he gets home, Tadashi will prepare snacks and drinks for them to share. 50/50 depends if they’ll shower together or Tsu wants their alone time, but regardless it always ends up with them taking about their day, to how they miss their boisterous sunshine boyfriend. They joke about bored they are without him, until Kogane comes home and tackle them with love

WHEN THEY HAVE TIME IN THEIR BUSY SCHEDULES they will go on arcade dates. Tsutomu has a love/hate relationship with those Claw Machine games as they are for “babies” according to them, but he can’t win anything and it infuriates them. Kogane is a whiz at them though, and always tries to win matching prizes for all three of them. He’s skilled at the games where you put the balls in the holes too. Thought, Goshiki is an expert at air hockey, and Yams is a professional when it comes to those coin games or the ones you have to stop at the perfect time.

COFFEE IS A BIG NO-NO for Koganegawa as he get SUPER hyper, but still gets it when them and Tadashi are alone, buttering him up. Goshiki always scolds him for giving them coffee, but Yams just isn’t immune to Kanji’s “puppy-dog eyes” like Tsu is.

CUDDLES ON THEIR HOUSEHOLD consists of Kogane and Tadashi making a “Tsutomu Sandwich”. Different positions are used too, but they use this method when she’s over-working herself. They just drag her to the couch or bed, and once they do, Goshiki knows she’s not leaving anytime soon, and doesn’t even try to fight them anymore.

BEFORE A GAME Yams always gives them foreheads kisses as a “good luck charm” Kanji loves them, and always asks for one, two…seven…more kisses. Tsutomu gets really embarrassed, especially when Tadashi does it around their teammates, so he instinctively moves away a lot. Especially since it’s someone from another school/someone who just got done kissed someone from another team. But Tadashi always acts really sad, which makes the other’s heart wrenching, so she hesitantly gives them a headpat so their love wouldn’t be sad anymore. But it was all an act on Yams part, just to get some type of affection.

A LOT OF THEIR FIRSTS were initiated by Koganegawa as he was just too excited to wait, pumped to share these intimate moments between the two he loves. Although, their first kiss was initiated by Tadashi when they were parting ways after a training camp. He kissed Tsutomu, then Kanji, which lead to her saying “You both get on my nerves…but I love you two.” Which ended them having an extra long group hug.

POST-TIMESKIP Yamaguchi always has sympathy for their two partners after their practices/games. So, he makes sure to give them the full treatment and pamper them, especially if they had a game vs each other. Goshiki gets all embarrassed by it even though they secretly like it and Kogane couldn’t be happier by all the attention.

GOSHIKI IS NOT THE…best at accepting touch. Although, she never did mind Kanji’s arm around her shoulders or her and Tadashi’s pinkies interlocked together. ♡

KOGANE ALWAYS FEELS sooooooo incredibly bad if he accidentally squeezes his partners a little too hard in an embrace as he doesn’t realize his own strength. But no worries, YamaGoshi always makes him feel better in the aftermath <3

THEY ALWAYS HAVE LOTS of movie marathons with tons of different picks. Sci-fi, romance, and surprisingly horror movies. The horror ones are picked actually from Koganegawa as they love when their partners cling onto him during the extra scary parts.

BOTH GOSHIKI AND YAMAGUCHI get really jealous when they see people flirt with Kogane…and the poor baby is so oblivious to flirting he just thinks they were being friendly. They never blame Kanji, so they always send the person flirting with their man death glares.

POST-TIMESKIP When Tsutomu and Kanji have a game against each other, Tadashi is always decked out in both teams merch. Usually Kanji’s spare jersey and hats and pins from Tsutomu. Sure, they get weird looks, but he’s a fan of both of them—their number one fan to be exact. Both of them can’t help but blush when they see Yams in the stands, cheering his heart out for both of them ♡

first time writing yamagata/goshiki, i’m super excited !!

20) things you said that I wasn’t meant to hear

Goshiki loved all of his senpai. Every single one of them. They all had their special loving quirks. Semi was kind and motherly, Reon too. Tendou was fun to be around and always knew how to have a good time.

But then there was Yamagata. And Goshiki didn’t know just how he felt about the libero. 

He couldn’t place the name of the feeling when speaking to him makes your heart flutter and your stomach tie up like you have a stomach bug. But when his senpai was near him, that’s the way he felt. 

Shirabu was no help when Goshiki went to ask him about it.

“How should I know?” Shirabu says, eating his sandwich and barely looking up from the book in his hands. 

“I just thought you’d have more experience than me!” Goshiki squeaked. 

Shirabu let out a groan, like helping Goshiki was the last thing he’d ever do and it was physically paining him to give his kouhai some advice. He shut his book and turned to stare Goshiki in the eye.

“Goshiki, you have a crush on Yamagata-san,” he tells him, very matter-of-factly. 

“I…what?” Goshiki asks, dark eyes wide. 

Shirabu sighs again, rolling his eyes, “you like him. You want to date him and kiss him and cuddle with him in bed.”

“N-no I don’t!” Goshiki’s tone if high pitched and scared and Shirabu can’t help but chuckle and smirk at how oblivious he was to his own feelings. Then, shly, Goshiki asks, “is that how you feel with Semi-san?”

Shirabu’s cheeks flush a deep crimson and he opens his book again, bristling, “no it isn’t. Mind your own damn business.”

Goshiki left the cafeteria feeling dazed and achy. Do I really like Yamagata-san? Maybe I’ll ask him tonight, when he’s helping me with my homework. Yeah. I’ll do that. Good idea, Tsutomu. Thank you, Tsutomu. 

That night, Yamagata was sprawled out on Goshiki’s bed, a textbook opened. The third years (and Kawanishi) took turns helping Goshiki with schoolwork, making sure their first year didn’t flunk out of the startling lineup. At first, it was order of Coach Washijo but they didn’t mind.

Most of them (i.e Yamagata and Semi) enjoyed helping the boy. 

Goshiki was so busy going through English nouns with Yamagata, it completely slipped his mind to ask about his so called “crush.” Maybe for the better, he thinks as he stifles a yawn.

“Tired, Tsutomu?” Yamagata asks, he can hear the smile in Yamagata’s voice. The same one when Goshiki spikes a straight that gets a point or when he babbles about being the ace next year.

“Mmmhmm,” Goshiki mutters and he feels Yamagata position him so he’s leaning against the third year. He feels his eyelids grow heavier and heavier with each passing second and Yamagata’s presence is warm and familiar and very inviting to just sleep. 

Then, a few minutes later, he heard a soft voice, softer than he’d ever heard Yamagata use and a hand running through his bangs.

“Love you, Tsutomu, sweet dreams,” then he felt Yamagata leave the room and close the door quietly. A small smile spread to Goshiki’s lips and he curled in a ball on his bed, his heart thumping happily. 

thank you for your request !! <3

(last updated 9/25/25!)

This post will be a quick rundown of all the other relevant NPCs introduced in the main storyline of the game so far. Note that Palace Rulers have been moved to their own post here!

School-Related

Mr. Hakozaki (left) is class 2C's science teacher. He's somewhat jumpy, and admits he doesn't spend a lot of time around other people, even idolizing a historical scientist who never shared the results of his research with anyone. Still, he seems extremely passionate about the science he teaches, even if he's anxious about actually teaching it to a group of students. Hakozaki also makes a brief appearance at the end of the sports festival event.

Mr. Shimonuma (right) is class 2C's civics teacher. He doesn't seem to have much faith in his students, and primarily enjoys when they don't know an answer, so he can correct them. He's stern in a slightly sadistic way, though he hasn't yet been seen to go so far as throwing chalk at his students (like Ushimaru does to Joker); it's all verbal.

Mr. Endo (left) is class 2C's English teacher. He's somewhat casual, with a slightly disinterested vibe, but he evidently know his subject, and doesn't seem to be slacking on teaching it. Still, he complains about the strangeness of English sometimes, and once mentions that he wishes the whole world spoke Esperanto.

Ms. Taniyama (right) is class 2C's world history teacher. She's friendly, and seems gentle with her students, while of course displaying a knowledge of and interest in her subject. She seems to have some interest in various forms of divination, though it only comes up offhandedly. Ms. Taniyama also makes a brief appearance in Kumi Katayama's Synergy, in its final event.

Mr. Nagara (left) is class 2C's literature teacher. He's very passionate and enthusiastic about his subject, and seems to generally feel emotions deeply. At the same time, he seems somewhat prone to tangents. He's the type to laugh at his own jokes, and is overall very reactive.

Kokatsu's Dean of Student Affairs is a man named Yamanashi (right). Yamanashi has a level of authority at the school, but he's still quick to become nervous if questioned or called out in any way, even if he stubbornly puts his foot down about whatever is under question. He tends to push any work he can off to Riko Tanemura (and then brag about how capable she is), and is quick to follow Akashi's new policies when they sound like they're in line with what the school wants, without much critical thinking.

His Shadow later appears in the third Palace, as Akashi's victim after Katayama, though his desires aren't strong or distorted enough to provide much power. Still, the Phantom Thieves manage to inspire a change of heart in him without stealing his Treasure, and the real-world Yamanashi resigns at the end of Chapter 3.

Other

Merope is Wonder's Velvet Room attendant. Though she has a very calm, collected, and straightforward demeanor, she is very dedicated to helping him however she can, including coming up with the idea of (and creating) the Phantom Idols that help him in combat.

She is also a Confidant of his, and it revolves around her "special project" to help improve his skills further. However, she is very interested in idols and idol culture- apparently believing them to be similar to the role Wonder plays- and much of her "special project" focuses on teaching Wonder more about idols, and how to be more like one. She is not only focused on being a good idol mentor towards Wonder, but also on herself being a proper idol fan, and refers to having done extensive research on the subject, though in practice she's evidently missing a bit of practical knowledge.

Merope seems to have a fondness for Wonder that may edge into romantic territory, though she's not romanceable. She casually refers to them doing things similar to what a couple might do- such as when they ride a ferris wheel together- and asks Wonder about it. However, as she tends to keep a very matter-of-fact tone, it's difficult to say whether she's actually flirting, or simply gauging his own reaction to understand him better.

More information about Merope's Confidant can be found here. Merope also makes appearances in both summer events and the sports festival event, among other places.

Marthym is a humanoid shadow that mainly dwells in Mementos. She is a self-described businesswoman, and notably runs the in-game store that takes actual money, as well as allowing players to buy gacha pulls.

Marthym's main story role seems to be her loose function as a guide to Mementos. She explains to the Phantom Thieves how to open up areas using tickets collected on that floor, and mentions that this benefits her as well as them, though she doesn't clarify how.

She also introduces the player to Paradise, which is an area where the player can see their guild, and includes special rotating boss fights that give extra rewards. Again, this seems to be explained as part of her business.

Yamagoshi (often called "Pops" in the English version) is the owner of the restaurants Heritage Kitchen (Toraiken in Japanese) and Victory Kitchen (Ashouken in Japanese), and has been running them for a long time, though his wife passed away at some point after their opening but prior to an elementary-school-aged Shun visiting. Miyazawa particularly harasses Yamagoshi, as he wants to be given ownership of Victory Kitchen, especially after Yamagoshi fell ill.

Shun sees him as a surrogate father, and Yamagoshi evidently cares a lot about him as well, as he set aside an heirloom to be given to Shun when he turned 18. [In Wonder's vision, when Shun loses the competition and is declared a phantom, Yamagoshi dies of a heart attack.]

Yamagoshi seems to believe in teaching others, as he opened Victory Kitchen specifically with the intention of it being a place for his employees to learn. He also believes in authentic flavor for his food, and is very proud of the restaurants' ramen's signature taste.

Masa is the person currently running the ramen restaurant Victory Kitchen, though Yamagoshi actually owns it.

Masa is an apprentice of Yamagoshi's, and believes strongly in the same principles as he does. It's mentioned his dream is to open his own restaurant. He's familiar with Shun, and seems fond of him. Prior to the start of the game, however, Masa began to give into Miyazawa's demands for ingredient changes and bribes, even as it ruined Victory Kitchen's food, because he didn't want Yamagoshi's restaurant to die completely.

After trying Shun's ramen in the competition Miyazawa challenged him to, he seems to have come to his senses, and becomes much more willing to stand up to Miyazawa, even if it risks his job. Masa is also the one to inform Shun when Miyazawa formally apologizes.

Masa later reveals that he and Katayama were friends in high school, and delinquents at the time. They seem to still keep in touch, as when Miyazawa got Shun fired from Victory Kitchen, Katayama came to Masa to ask what happened. Masa also makes an appearance in Kumi Katayama's Synergy, as well as a brief appearance at the end of the sports festival event.

Daichi Ousaka, formerly a male idol/band member, is currently working as Takami Shimotsuna's "dog"/assistant, though she's blackmailed him into doing so. While it seems he initially put up a fight, after two years he has been (perhaps somewhat literally) beaten into submission. The second portrait, Shimotsuna's cognition of Daichi within her Palace, acts as a major boss fight during the Phantom Thieves' infiltration of her Palace.

There's also some history between Shouki and Daichi, as Shouki acted alongside Daichi at one point when he was little. Shouki used to look up to him, but could never understand why Daichi abruptly decided to "go solo" and switched agencies. After finding out about the blackmail- which Daichi went along with in order to protect his original talent agency's president, who punished another idol that sexually assaulted a female idol at their agency- Shouki becomes determined to steal back Daichi's desires and save him.
