History YMMV / Haikyuu

* DiagnosedByTheAudience: Kageyama is often speculated to be autistic due traits such as being unable to understand body language, difficulty expressing his emotions in a healthy manner and understanding the emotions of others.

* DiagnosedByTheAudience: Kageyama is often speculated to have some sort of disorder due to his personality. He has difficulty expressing his emotions in a healthy manner and understanding the emotions of others. Outside of volleyball, he's a very literal thinker and volleyball seems to be the only thing he's interested in.

** "No debi hacer eso jaja" [[labelnote:Explanation]][[https://twitter.com/kalu_atencio/status/1430619298826002432 A shot of a character lying in bed looking contemplative]] got the aforementioned caption (which translates "haha I shouldn't have done that") and quickly spread throughout Latin-American memespheres as a reaction image.[[/labelnote]]

** Diechi. [[labelnote:Explanation]]During their match with Shiratorizawa, Tanaka accidentally collides with Daichi, and fans make jokes about Daichi dying. In response people also say "nice kill, Tanaka."[[/labelnote]]

** Calling [[{{Jerkass}} Tsukki]] or Oikawa a shit. In a similar vein, referring to Oikawa, Kuroo, Tsukishima, and sometimes even Lev as "trash" in various ways.[[labelnote:Explanation]]Kuroo, Tsukishima and Oikawa InUniverse like to act TheGadfly to their respective teams, making them jokingly known as "trash". Lev is less of a troll but has a habit of annoying his peers, hence his honorary trash status.[[/labelnote]]
** [[TeamMom Sugamama!]] Alternatively, Mama Suga. Also [[TeamDad "Dadchi"]]. [[labelnote:Explanation]]Sugawara is a very good TeamMom of Karasuno, leading to a pun of his name and "sugar mama". Daichi's nickname came about due to his TeamDad role and the popularity of Daichi/Sugawara pairing. TeamMom and TeamDad levels even extend to other teams, i.e Yaku is the TeamMom of Nekoma, with the "father" either being Lev Haiba (popularised due to the Yaku/Haiba fandom) or Kuroo (who plays a similar strict but good-natured fatherly captain role to Daichi.[[/labelnote]]

** [[IncrediblyLamePun Solia K. Rabu]]. [[labelnote:Explanation]]Kuroo and Bokuto get sidetracked when Tsukishima earnestly asks for them and Akaashi advice about doing club activities. In Japanese, the two third years mishear Tsukishima saying "takaga bukatsu" as "tada no bukatsu" (both mean "only a club"), giving them an epiphany that it sounds like a name ("Tada Nobukatsu", in Japanese naming order), puzzling Tsukishima and Akaashi; one of the fan translations phrases this as "only a club" and "solely a club", with the third years thinking the latter phrase sounds like the name Solia ("solely a") K. Rabu ("club").[[/labelnote]]

** Oya? Oya oya? Oya oya oya? [[labelnote:Explanation]] Akaashi, Kuroo and Bokuto's NoblewomansLaugh, which can be translated as "Oh ho ho ho". The way they say those lines in the anime was found to be very amusing by Western fans.[[/labelnote]]
** "But why?"[[labelnote:Explanation]][[http://imaginethehaikyuukids.tumblr.com/post/86446579714/ka-gay-ama-imaginethehaikyuukids-imagine Originated from „Imagine the Haikyuu kids” tumblr]] as a standard Hinata's response to anyone having a crush on Tsukishima.[[/labelnote]]

** "You should have come to Shiratorizawa." [[labelnote:Explanation]]Ushijima thinks that Oikawa is wasting his talents at Aoba Johsai and should have gone to the strongest school to be his setter. Instead of telling him this when it would be effective, however, Ushijima decides that to ''open'' their conversation this way minutes after Aoba Johsai lost to Karasuno. It comes on pretty strong, and you get the idea that Oikawa has heard this sentiment before. [[/labelnote]]
** Farmer Ushiwaka. [[labelnote:Explanation]]Ushijima says that Shiratorizawa is fertile soil for strong players, whereas Aoba Johsai is barren land. Complete with background illustrations. Furthermore his nickname (Ushiwaka) translates to cowboy.[[/labelnote]]

** Diechi. [[labelnote:Explanation]]During their match with Shiratorizawa, Tanaka accidentally collides with Daichi, and fans make jokes about Daichi dying. In response people also say “nice kill, Tanaka.”[[/labelnote]]

* NightmareFuel: Furudate used to do horror manga. Naturally, ''Haikyuu!!'' is not immune to such horrifyingly drawn scenes.
** Kageyama's terrifying face after Hinata hits him in the head with a failed serve. Hinata himself says it's his scariest memory.
** Hinata's smile when he's getting overly hyped up in his matches (such as [[spoiler:the match against Nekoma]]) often crosses into creeper territory.
** The look in their eyes that quite a few characters get when they reach peak intensity comes off as chilling enough to startle several players who bear direct witness. The biggest example is Hinata's [[https://wallpaperaccess.com/full/2009625.png absolutely CHILLING expression]], which was sent to and ''able to'' leave [[TheStoic Ushijima himself]] taken aback!

* AuthorsSavingThrow:
** [[spoiler:The third years' graduation being given few panels and little fanfare]] in Chapter 369 was met with ire from fans who were looking forward to the moment and thought the characters in question deserved more. In the official volume release, [[spoiler:extra pages were added where Daichi reminisces over his last three years of high school volleyball and tells Kageyama and Hinata he's looking forward to their progress, which at least gives the graduation a little more emotional impact.]]
** Sakusa being such a mysterious player [[spoiler:to the point that he and Itachiyama are never shown playing during Nationals]] was seen as a let-down for fans interested in him and his reputation. After [[spoiler:the TimeSkip, he's made a pro-player of the MSBY Black Jackals (the team that is also home to Bokuto, Atsumu and eventually Hinata), thus giving him another chance to shine in a match and reveal his backstory]]. This also [[spoiler:sheds more light on Itachiyama, notably giving the captain some proper characterisation and a happier send-off than his tearful injury-induced exit out of Nationals]].

** Akaashi began as a surprisingly popular character, debuting at 14th place in the second character poll despite only having appeared at the Tokyo Camp arc at the time as the supportive deadpan teammate of Bokuto (who played a bigger role in the arc for Tsukishima's character development yet placed 18th).
** Sakusa is rather popular considering relatively short appearance in the Nationals arc. [[spoiler:Although he makes a comeback post-Timeskip as a more present character, he's still less developed than his teammates and his opponents.]]

** As the series has progressed, so have the {{Crack Pairing}}s. There are so many interesting, dynamic characters now that just about ''every single character'' can become a magnet for ships. For example, other than Hinata, Kageyama's ships include Sugawara, Oikawa, Iwaizumi, Tsukishima, Yamaguchi, and Yachi. The non-players and girls are not immune either, as Yachi's ships include Shimizu, Hinata, Yamaguchi, Kageyama, Tsukishima, Asahi, Kenma, Tanaka, Nishinoya, and Lev. Even couples like [[KissingCousins Sakusa x Komori]] or [[{{Twincest}} Atsumu x Osamu]] have their own collections of fanworks. It's pretty much Everyone x Everyone at this point.

* SelfFanservice: In canon, Oikawa is the only guy noted to be particularly attractive. Fans tend to pretty up other characters such as Sugawara, Kuroo, Kenma, and ''especially'' Akaashi, who is often portrayed as stunningly handsome and the object of Oikawa's envy in fan works.

** Kiryuu and Sakusa are hyped as the other top high school aces in Japan alongside Ushijima, with Sakusa's team Itachiyama in particular considered the biggest threat. While Kiryuu's skills are shown off and his characterisation is well done, [[spoiler:his only significant appearance is his loss against Fukurodani, which can feel shorter than he deserves]]; meanwhile, Sakusa [[spoiler:is never even shown in a high school match (other than the match point against Fukurodani in the Preliminaries), leaving one to wonder if there was any point in giving any attention to the famous second-year ace]]. AuthorsSavingThrow has him [[spoiler:appear on Hinata's V-League team after the TimeSkip to give him more exposure, but his lack of presence in the Nationals arc as a Top 3 Ace is still strongly felt]].

* GoodBadTranslation: It's technically correct to translate the Japanese ''waseigo'' volleyball terms to their Western equivalents, such as feint -> dink, receive -> dig/bump, one touch -> deflected etc. Many fans (especially those who don't already follow real-life volleyball) nevertheless become accustomed to hearing the original Japanese terms in the anime and end up preferring the literal translations.

** The French dub [[labelnote:Explanation]]The French dub of the anime is usually considered very {{narm}}y by French viewers of the series, who prefer to watch it either in the original Japanese or the English dub, due to but not limited to the GratuitousEnglish in Yū Nishinoya's battle cry now sounding like he's mourning rather than [[CallingYourAttacks Calling His Attack]], robotic speech from some characters and Hinata's breakdown upon losing inspiring tears of laughter rather than sorrow.[[/labelnote]]
** Diechi [[labelnote:Explanation]]During their match with Shiratorizawa, Tanaka accidentally collides with Daichi, and fans make jokes about Daichi dying. In response people also say “nice kill, Tanaka.”
** Anime Villain Oikawa. Oikawa is often included in people's lists of favorite anime antagonists with people joking about how a rival volleyball player is grouped alongside mass murderers, masterminds, sociopaths, and tyrants.[[/labelnote]]

** Miya twins who?[[labelnote:Explanation]]Since the Miya twins look similar, people started labeling other characters that look similar like the Miya twins.

* FandomRivalry: Many long-time volleyball fans are not fond of the Haikyuu fangirls and fanboys raiding literally every single possible volleyball video. Nations League? Expect Haikyuu comments. CEV Champions League clips (a ''European'' competition followed by few Americans, where most of the diehard Haikyuu fanbase is located)? Haikyuu. Olympic volleyball? ''Haikyuu''. The invasion eventually culminated in pissed off volleyball fans starting to make hate videos directed straight at the fandom for their immaturity, shortsitedness (i.e. they did not come to appreciate volleyball) and overall disrespectfulness.
