HaruhiSuzumiya/{{Tropes A-E}} | '''Tropes F-I''' | HaruhiSuzumiya/{{Tropes J-N}} | HaruhiSuzumiya/{{Tropes O-S}} | HaruhiSuzumiya/{{Tropes T-Z}} |
----
!!!''LightNovel/HaruhiSuzumiya'' provides examples of the following tropes:

* {{Facepalm}}: After [[Series/StarTrekTheNextGeneration Picard]], Kyon is the best known Facepalmer on the Internets.
** Near the end of the ''Disappearance'' movie, after Kyon [[spoiler:wakes up in the hospital, the first thing he says to Haruhi when she sees he's awake is, "Hey."]] Itsuki does a huge facepalm behind Kyon's back as soon as he says that.
* FakeBand: ENOZ, whose name is a homage to the real band ZONE.
* FakeVideoCameraView: In ''The Adventures of Asahina Mikuru''
* FallingInLoveMontage: Parodied without mercy in "The Adventures of Mikuru Asahina."
* FalseCameraEffects: Most notably, the first/zeroth episode consists of a simulated student film; but the whole anime has scenes drawn with simulated lens flare, barrel/pincushion distortions and fisheye lenses all over the place.
* FanDisservice: In episode six of season two, Koizumi's swim trunks are swapped with a tiny, black Speedo. Still fanservice [[EstrogenBrigade to some]], though.
* {{Fanservice}}: Special mention to episode [[spoiler:three]] of season two. [[spoiler:It's essentially a repeat of episode two by nature of being part of a GroundhogDayLoop, but has gratuitous amounts of fanservice for both guys and girls]]. Specific focus given to Itsuki's and Kyon's bodies during [[ShirtlessScene shirtless scenes]] [[spoiler:and an ''additional'' shirtless scene for Kyon at the beginning (he was wearing a shirt that time last episode!)]] as well as to Haruhi's and Mikuru's... assets. Also, close ups to the face play up Itsuki's [[{{Bishonen}} bishonen-ness]] and the girls' [[{{Moe}} moe-ness]] (and the entire episode seems to ''intentionally'' defy anyone to resist hugging Yuki). To cap it all, there's some ShipTease all around for Kyon/. (Kyon has reactions to each of the girls' aforementioned {{Moe}} facial expressions, [[GayOption and even Itsuki arguably has his bit of ship tease]]). The episode just screams "intentional gratuitous fanservice."
* FeelNoPain:
** Yuki. [[spoiler: Grapples with a combat knife by its blade. Intercepts lasers with her palm. Takes several steel spikes through the chest. Impaled with steel spikes the width of a ship's mast and lifted off her feet. Only the latter is enough to make her fall over -- and even then, it's from ''exertion'', not pain.]]
** Then, of course, [[spoiler:it gets ''horrifically'' subverted in ''Disappearance'' -- Yuki has made herself fully human to finally be with Kyon. Now that she's human, though, ''she can feel pain'' and has a natural terror of it... meaning she ''can't'' rush to his rescue when Ryoko shows up for round two, as her old crazy stunting would only get her killed in agonizing minutes as a human. It doesn't help that she can't even ''remember'' her old stunts due to the way she rewrote the world and ''herself''.]] [[spoiler:This can lead to a little confusion when it looks like she grabs the knife ''[[{{Badass}} anyway]]'', but later on in the novels we learn a bit more about the rest of the incident and it turns out the actual trope is still in full force]].
* FemaleGaze: Exactly how Tsuruya sizes up Kyon when they meet in ''The Boredom of Haruhi Suzumiya''.
* FestivalEpisode: Part of "Endless Eight".
* {{Fetish}}:
** Kyon admits to Haruhi that he has a [[{{Moe}} thing]] for ponytails, and encourages Yuki to lose the glasses because he isn't a fan of {{meganekko}}.
** In one of the novels, he admits to himself that Mikuru's maid outfit is his favorite one and wonders if he has a maid fetish.
** And later novels he subverts this trope by noting he finds seeing Yuki [[LimitedWardrobe in her uniform]] especially comforting, but not because he has a [[{{Joshikousei}} sailor uniform]] fetish.
* FigureItOutYourself: Both Mikuru Asahina (big) and Yuki Nagato give Kyon very incomplete information about [[spoiler: how to ... save the world from Haruhi.]] Kyon puts both clues together at nearly the last minute to do just so. [[JustifiedTrope Justified]] to some extent because both Asahina and Nagato are constrained by rules. It's actually pretty obvious. Kyon is just [[SelectiveObliviousness selectively oblivious]] as long as possible.
* {{Filler}}:
** In the books, "Endless Eight" was a brief story that lasted about 30 or so pages and the time loop was broken without the reader seeing any other repeats after [[spoiler:Kyon has Haruhi help him with his homework]]. In the anime, it's eight episodes of near-identical footage and dialogue, reanimated from scratch ''every single time'' (which in turn angered those who viewed the affair as a waste of money and season). You can just skip episodes 3-7 of second season and literally miss nothing.
** Although overshadowed by "Endless Eight", the first season episode "Someday in the Rain" had 3 minutes and 23 seconds of continuous filler, with irrelevant chatter going off in the background while Yuki reads, occasionally turning the page. It was interrupted for a couple seconds with a scene of of Kyon riding the train.
* FirstKiss: The climax of season one.
* FirstNameBasis:
** Kyon refers to Haruhi by her first name, no honorific extremely soon after the SOS-dan's founding, and she's the only one to call him by just his nickname, no honorific. Also notable is that Yuki never, ever refers to Kyon by name, only "you". Neither does Koizumi.
** Also [[ShipTease significantly]], Haruhi's the only person that Kyon addresses by first name and no honorific.
** In the student film, the characters are supposed to refer to each other by first name, but the actors sometimes flub their lines and use last name.
** End of the ''Disappearance'' movie (not the novel): "I'm sorry, Nagato...Yuki." However, it's unclear if he was using her name or simply pointing out the fact that it had started snowing (or both).
* FirstPersonSmartass: Kyon, in an combination of his DeadpanSnarker and {{Narrator}} roles.
* FirstTimeFeeling: In ''Disappearance'', Kyon discovers that Nagato [[spoiler: set the whole plot in motion by developing emotions and, unable to deal with them, stole Haruhi's powers and remade the world]].
* FiveManBand: Lampshade hanging, Haruhi purposely creates the club to her expected stereotypes. Although, it should be noted that the roles change depending on the point of view. According to Haruhi, she is TheHero, Yuki is TheSmartGuy, Koizumi is TheLancer, Kyon TheBigGuy, and Mikuru is obviously TheChick. But for Kyon, Yuki is TheBigGuy (and to an extent, his Lancer) and Koizumi is TheSmartGuy. So Haruhi would probably be Kyon's Lancer or vice versa. (Guess who he calls first when something happens....) [[spoiler: He calls ''Haruhi'' when a the [[ItMakesSenseInContext time-shifted version of Mikuru(Michuru)]] gets kidnapped. Luckily she thinks it's a joke.]]
* {{Flashback}}: For example, after the SOS brigade finishes the movie, we see what happens right after Haruhi meets Kyon at the end of ''Melancholy Part VI''.
* FlashStep: Done by Yuki twice to stop Mikuru's eye beams.
* {{Foreshadowing}}:
** Episode 00 has [[spoiler: everyone in more or less role they play in the series, Kyon's the Narrator, Yuki's an Alien, Mikuru's a time traveller and Haruhi's the Director so everyone has to bow to her wishes]].
** Kyon makes an offhand comment in Novel 11 that Koizumi is the last member of the brigade you would want to see angry. [[spoiler:And who should be the one to explode (literally) at Fujiwara in the climax?]]
** In one early episode (chronologically, not the broadcast order) Yuki mentions that Haruhi would never believe Kyon if he told her about Yuki [[spoiler:being an alien. This is exactly what happens when he finally does decide to tell her at the end of the series]]
** In the third novel/first series story "Remote Island Syndrome," Haruhi notes that it's better to go to an island in the summer, because you can't get caught in a blizzard unless it's the winter, with Kyon even noting that isn't something to hope for. Sure enough, in the fifth novel, they visit the mountains in winter and get caught in a blizzard.
** The anime has a subtle one in "The Day of Sagittarius." As the Brigade members walk home together after accepting the Computer Club's challenge, Haruhi confidently tells Mikuru that her skills will put Admiral Nelson to shame. At Trafalgar, Nelson led the first attack wave personally and went straight after the enemy flagship, which is exactly what Haruhi's strategy for playing the game later turns out to be. The dub changes it from Nelson to Admiral Halsey, but since Halsey's strategy for carrier-based combat was, "Find the enemy as fast as you can and hit him with everything you have," the foreshadowing of Haruhi's playing style still fits perfectly.
* ForScience: Studying Haruhi? Okay. [[spoiler:Killing one of your classmates]] to see how she'll react? [[SarcasmMode Ooookay...]]
* ForgotTheCall: There are scenes that indicate that Haruhi is up against a mental block as opposed to just being totally clueless. [[spoiler: Note how something stops her in midstream here: "I'm the brigade chief and director and ... Anyway, I won't allow you to go against me!"]]
* FortuneTeller: Yuki in "Live Alive". However, as Kyon points out, she doesn't understand the difference between telling somebody their fortune and predicting their future; for example, she tells someone that he'll drop his ice cream in ten point three minutes.
* FourTemperamentEnsemble: ''All in Haruhi combined''! It's... totally awesome.
* FourthWallPsych: In TheMovie when Kyon asks a question to "the world".
* FreezeFrameBonus: In the first part of the two-episode island mystery arc, there's a shot of the sunset, and then a wave passing over the beach. Pause in the two or three frames before the wave crosses the screen, and you'll see a bizarre sketch in the sand of...[[TrueArtIsIncomprehensible something.]] Haruhi? A caveman? [[FanDisservice Itsuki in a bikini?]]
* FrickinLaserBeams: For the most part averted; nobody is able to dodge them and they're even invisible! ''Completely'' averted if you can believe Yuki can run at faster-than-lightspeed to block them ([[PhysicalGod and she probably can]]).
* FrothyMugsOfWater:
** Underage drinking is a big no-no to the Japanese (or at least depictions of it are). In the ''Sigh'' novel, Mikuru was slipped tequila; the anime changed this to amazake, which is seen as alright to give infants, which makes Mikuru seem [[CantHoldHisLiquor much, much worse at holding her liquor]] (not that she wasn't already bad in the original). In a rare inversion, the English Dub actually changes it to sake.
** In ''Boredom'' the ''Remote Island Syndrome" segment has the entire cast get very drunk twice (with the possible exception of Yuki). The anime adaptation cuts this out entirely and drags Kyon's little sister along just to make sure everyone stays on their (relative) best behavior.
* FunnyBackgroundEvent:
** While Haruhi is talking about how she doesn't see the point in love, there is a brief cut to a random scene outside where a male student helps out a female student with something, and it's all very flirty. Later in the episode, there's another brief cut to where the female student shoves the male student to the ground and runs away.
** Multiple in "Live Alive":
*** Two TV personalities "HardGay" and Akihiro Miwa grab Kyon as he's walking through the halls.
*** When Kyon is leaving the building at the festival, there's a mom getting a balloon for her kid. The kid protests, and the mother threatens to leave the kid behind.
*** When Kyon goes into the hall so he can doze through a concert (having just been up all night editing the brigade's movie), someone else appears to have already fallen asleep a few rows in front of him.
* FunSize:
** Tsuruya-san's fan interpretation, Churuya-san.
** Now ''{{Haruhi-chan}}'' as well.
** Achakura, Ryoko's (still psychotic) but barely two-feet-tall incarnation from ''Haruhi-chan'', is notable in that she's tiny compared to the rest of the heavily [[{{Chibi}} chibified]] cast.
* FunWithAcronyms: SOS Brigade stands for '' '''S'''ekai wo '''O'''oi ni Moriageru tame no '''S'''uzumiya Haruhi no Dan'', or ''Haruhi Suzumiya's gang whose purpose is to greatly enliven the world''. To [[{{Woolseyism}} maintain the joke]], the {{fansub}}bers and the official manga and light novel, gave this as '' '''S'''ave the World By '''O'''verloading It With Fun -- Haruhi '''S'''uzumiya's Brigade'', while the official dub translated it as '' '''S'''preading Excitement All '''O'''ver the World with Haruhi '''S'''uzumiya's Brigade''.
* FutureImperfect: Asahina sometimes does this. For example, she comments on Koizumi's telescope being "not very different from Kepler's." This particular example could actually make sense, who knows how future telescopes work? In Asashina's time they might use non-optical telescopes, or more conventional telescopes built into contact lenses, or even simply direct the visual input into their minds. From this point of view, there is little difference between two cylindrical telescopes with glasses, and only half a millennium's development between them.
* GagSub: ''[[http://www.youtube.com/watch?v=Xc-uGW5gmlg The Adventures of Nagato Yuki]]''
* GainaxEnding: The final chapter of ''Surprise'' is the most confusing one yet.
* {{Gainaxing}}: Poor Mikuru. Particularly noticeable in the opening.
%%* GenericCuteness
* GenkiGirl: Haruhi, as well as minor character Tsuruya.
* GenreBusting: It's depicted as Sci-Fi, come on...
* GenreSavvy: Haruhi insists on seeing GenreTropes everywhere, even where they might not have existed; in a completely different way, Itsuki attempts to "appease" Haruhi by providing textbook, predictable examples of tropes. Haruhi does not do "predictable", so these tend to mutate.
* GirlInABox: Kyon's little sister hid in his duffel bag so he would take her on vacation with him. Amusingly, RealityEnsues - Kyon immediately notices that his bag is a good 30 kilos heavier than it should be and catches her. In the anime he brings her along anyway, whereas in the {{light novels}} he sends her back home.
* GirlishPigtails: One of Haruhi's haircuts. Also, Mikuru in her waitress outfit.
* GirlWithPsychoWeapon: [[spoiler: Ryoko Asakura]].
* GivingSomeoneThePointerFinger: Sometimes played straight but also used to reference PhoenixWrightAceAttorney. Or just outright parody Phoenix Wright, down to the dramatic speed lines.
* AGlassOfChianti: The Computer Club President during the DeepImmersionGaming. Also Haruhi in the manga, when describing the importance of {{moe}}. A glass of [[FrothyMugsOfWater grape juice]], that is.
* TheGlassesGottaGo: Yuki Nagato, of course.
* {{God}}: Or something similar...
* AGodAmI: Subverted and/or reversed: [[spoiler:the character with godlike powers, Haruhi, has ''no'' idea she has them. Her delusions of grandeur are just that.]]
* GodlySidestep: Kyon asks Nagato, after treating with beings that are effectively ghosts of alien lifeforms, what happens after humans die. Her answer? Classified information.
* GoMadFromTheRevelation: Nakagawa in "Love at First Sight", who [[spoiler:senses the Integrated Data Sentient Entity through Yuki; the sensory overload causes him mental illness and obsession with Yuki.]]
* GoodAllAlong: [[spoiler: Sasaki.]]
* GratuitousEnglish:
** This trope is mostly invoked by Koizumi. Probably the most ridiculous is his line in "Endless Eight": "Perhaps grab her from behind, and whisper '[[NarmCharm AI LAAV YOU]]' [[http://www.youtube.com/watch?v=x0KXbV75Ts8&fmt=18 into her ear."]]
** Kyon tends to speak English a lot too, mostly in "Endless Eight" - highlights are exclaiming "Excellent!" upon seeing Mikuru in a yukata, and his hilarious outburst of "Three days!?" when Haruhi tells him how long it took her to finish her summer homework.
* GroundhogDayLoop: "Endless Eight", in which the SOS Brigade gets stuck repeating the same two weeks of summer vacation nearly 15,500 times and suffer from severe deja vu throughout -- except for Haruhi, who remembers nothing, and Yuki, who remembers '''''[[AndIMustScream everything]]'''''. The anime adaptation makes you feel it too, dragging the short story out ''beyond'' 15,500 and into ''eight'' repetitious episodes.
* GroundhogPeggySue: See above. An interesting variation in that [[spoiler:only one character is aware of the situation, and she is unable to take action herself]].
* HandsOffParenting: All characters' parents are so absent, they're not even mentioned. Yuki lives alone, being an alien, Itsuki's and Mikuru's parents are never shown, though presumably them being secret agents has something to do with their surprising amount of free time. Even OrdinaryHighSchoolStudent Kyon is at home with his sister, but his parents are never seen. Both Kyon and Haruhi's parents are ''present'' (Kyon's sister often acts a a go-between for him and his mother-fetching him for meals, waking him up, etc-and is once even heard complaining to her one time when he kicks her out of his room), they're just ''[[TheUnseen unseen]]''. Haruhi's mother is mentioned very briefly in the beginning of ''Surprise'', where she's explained to be a LethalChef.
* HaveWeMet: Haruhi casually asks Kyon this in their first conversation. [[spoiler:She has in fact met him before, but Kyon hasn't; he [[TimeTravelTenseTrouble will meet her three years ago a couple of months later]].]] So it's really a case of HaveWeMetYet. There's a similar time-travel paradox in the first meetings of Kyon and Mikuru: [[spoiler:Kyon and [[FutureBadass (future) Mikuru]], as the latter tells the former something she thought he already knew. [[TemporalParadox Hilarity]] ensues.]]
* HaveIMentionedIAmHeterosexualToday: Kyon launches into a paragraph-long example in ''Disturbance'' to dispel some of the HoYay that had been accumulating.
* HeadDesk: Kyon can be seen doing this in the [[AnimeThemeSong opening theme song]], ''[[http://www.youtube.com/watch?v=mIKRn1dbT28 Bouken Desho Desho]]'', cementing his OnlySaneMan role in the SOS Brigade.
%%* HealingFactor: Yuki.
* HeelFaceReturn: [[spoiler:Ryoko in the tenth novel]].
* HeelFaceTurn:
** In the tenth novel, [[spoiler: Ryoko, who comes to defend Kyon from Kuyo rather than kill him. At least, she's definitely more willing to listen to her superiors.]]
** [[spoiler: In the following novel, Kyouko also has one, being the only member of the "Anti-Brigade" to turn good (Sasaki, who was GoodAllAlong, not withstanding.)]]
** Haruhi has one in ''Sigh'' after Kyon makes her realize that what she had done to Mikuru is a potential Moral Event Horizon on her part. Said MEH thus becomes either a subversion or an inversion.
* HeelRealization:
** Arguably Haruhi in ''Sigh'' when Kyon [[WhatTheHellHero calls her on her treatment of Mikuru]]. After that incident, she is much more consistent in her PetTheDog moments and less consistent in her KickTheDog moments.
** Kyon has one in ''Disappearance'' where he realizes that [[spoiler: his inaction and over-reliance on Yuki is part of what led to her hijacking Haruhi's powers and re-writing the world.]]
** [[spoiler: Kyouko also has one accomponied by a brief {{Villainous BSOD}}.]]
* HeroicBSOD: Kyon is positively distraught in ''Disappearance'' when he finds [[spoiler: no one remembers Haruhi or the SOS Club, to the point of shouting at and shaking people visibly frightened by his outburst.]]
* HeroicRROD: [[spoiler:The beginning of Book 10 reveals that Yuki's "flu" is a result of the Data Overmind using her in an attempt to contact/understand the utterly alien [[StarfishAliens Canopy Domain.]] This weakens Yuki so much that she can barely communicate. More than usual, that is.]]
%% HeyItsThatVoice is trivia and goes on the Trivia page. %%
* HighSchoolHustler: Haruhi has gotten away with hijacking the literature clubroom, blackmailing the Computer Club President into giving a computer away for free by having him grope Mikuru, dressing as [[PlayboyBunny bunnies]], submitting her film to the culture festival with the applications already closed...
* HijackingCthulhu: There was a story arc where someone stole Haruhi's powers.
* {{Homage}}: One scene plays out as a blatant ShoutOut to the ''AceAttorney'' series, complete with all the [[GivingSomeoneThePointerFinger epic finger pointing]], speed lines, and character sprite animations. [[http://www.youtube.com/watch?v=Tj-g6tWM2WU This video demonstrates.]]
* HostileShowTakeover: The entire plot of ''Disappearance''. [[spoiler:Yuki rewrites reality to change herself into the main character: a painfully introverted -- but completely human -- bookworm with a crush on Kyon. Meanwhile, Haruhi and Itsuki are PutOnABus and Mikuru gets [[{{Shipping}} shipped]] with Tsuruya so Kyon can't get close. Got its own [[Manga/TheVanishingOfNagatoYukiChan spin-off manga!]]]] Of course, [[spoiler:once Kyon ''finds'' Haruhi and gets her going, she immediately sets out taking the show back for herself. Even in the official AlternateUniverse manga, she seems poised to steal the spotlight...]]
* HowWeGotHere:
** The written Remote Island Sydrome opens discovering Keichi's body, then flashes back to explain how events transpired.
** The movie.
* HumanAliens: The Interfaces...whatever they actually are.
* HumanoidAbomination: All the Data Interfaces except Yuki, according to Kyon. [[RealityWarper Haruhi herself might be this...]]
* HumansAreSpecial: Humans apparently are the only organic lifeform that can actively seek knowledge and continuously advance themselves.
* IAmWho: Haruhi Suzumiya. Kyon also occasionally discusses or invokes this trope when thinking about his own role.
* IChooseToStay: In ''The Disappearance of Haruhi Suzumiya,'' Kyon is given the opportunity to [[spoiler:leave the SOS Brigade and Haruhi's fantastic world of aliens, time travelers, and espers, both of which he's complained about for the entirety of the series up to this point, behind him, and start a new life.]] The offer comes complete with [[spoiler:new friends to make and even a potential love interest]], but in one of the most moving [[InnerMonologue inner monologues]] in the series, [[spoiler: he decides that he can't leave that world behind, even going so far as to say he'd have to be an idiot to walk away from it all.]]
* IdenticalGrandson: In the manga, [[spoiler: Kyon looks just like his grandfather.]]
* IdiosyncraticEpisodeNaming: Every book, video game, and full-length album is entitled "''Suzumiya Haruhi no ___''", or "The ___ of Haruhi Suzumiya".
* IdiotHair: Taniguchi.
* IfYouEverDoAnythingToHurtHer: Disappearance!Asakura to Kyon regarding Yuki. See the extra note under This Is Unforgivable.
* IJustWantToBeNormal[=/=]IJustWantToBeSpecial: The series plays with these tropes [[ZigZaggingTrope in a pretty elaborate manner]].
** Kyon spent his childhood [[IJustWantToBeSpecial dreaming about having supernatural powers]] or hanging out with people who did, but he says that he got over it and now he just [[IJustWantToBeNormal wants to be normal]]. [[spoiler:This is subverted in ''Disappearance'': when push comes to shove, Kyon decides against an ordinary life, and admits that he is excited to hang out with an alien, time traveler, esper and Haruhi. So Kyon is really IJustWantToBeSpecial posing as IJustWantToBeNormal.]]
** Haruhi lived a happy childhood until she discovered that her life was ordinary, and then decided that [[IJustWantToBeSpecial she would become an extraordinary person]], or find extraordinary beings like aliens, time travelers, espers or sliders. She creates the SOS Brigade with that latter purpose. [[spoiler:Subverted, however, because it turns out that what she most enjoys is hanging out with her fellow brigade members and doing ordinary high school activities together, like playing baseball, doing summer activities or helping them do their summer homework. So Haruhi is really IJustWantToBeNormal posing as IJustWantToBeSpecial.]]
** Kyon and Haruhi are [[{{Foil}} foils]] to each other when it comes to these tropes. [[spoiler:But the remarkable thing is that they show subverts the ''direction'' of the foil; Kyon's actually the one with IJustWantToBeSpecial, and Haruhi the one with IJustWantToBeNormal.]]
** [[spoiler: Yuki]] is a pretty straightforward case of IJustWantToBeNormal.
* ImageSong: The amount of additional music done for the show is staggering, rivaling ''MahouSenseiNegima''. 16 character albums, 4 soundtracks, 3 drama [=CDs=], 8 combination soundtrack and drama [=CDs=] that shipped with one of the [=DVD=] versions, a live concert, and an ''orchestral'' concert.
** First set: Haruhi Suzumiya, Yuki Nagato, Mikuru Asahina, Tsuruya, Ryoko Asakura, Kyon's sister, Emiri Kimidori, Itsuki Koizumi, and Kyon.
** Second set: Haruhi Suzumiya, Yuki Nagato, Mikuru Asahina, Itsuki Koizumi, Kyon, Tsuruya, and Taniguchi.
* ImportantHaircut:
** Haruhi cuts her hair after meeting Kyon, about the same time she changes from being antisocial to being outgoing and happy. Before that, she changed her hair based on the day of the week, with a full-blown explanation as to why. It's implied she did this to get Kyon to comment on it.
** Haruhi can sometimes be seen holding her hair in a ponytail after [[spoiler: Kyon claims to have a thing for girls with ponytails in a "dream,"]] with the most obvious example being [[spoiler: that she has her hair in a ponytail the very next day after said "dream."]] In fact, at one point, when deciding on whether or not to put Mikuru's hair in a ponytail, Haruhi [[spoiler: looks at Kyon and immediately drops the idea out of jealousy]]. She does it again the day after Kyon blows up at her over her mistreatment of Mikuru during the shooting of their movie.
* ImprobableAge: [[spoiler: Koizumi may or may not actually be the one in charge of his Organization.]]
* ImTakingHerHomeWithMe: Tsuruya says this about Mikuru in ''Sigh''. Then they actually go to Tsuruya's house to do a scene.
* IncestSubtext: Though Kyon is most definitely not attracted to his sister, he is attracted to Mikuru, and at least six times, he pointed out how similar she is to his sister, causing an inverted example of the trope. He also sees simularities between Haruhi and his sister as detectives.
* InconsistentDub: An incredibly minor example, but when watching seasons 1 and 2 together in chronological order, you may notice that while the season 2 episode "Bamboo Leaf Rhapsody" uses the term "{{Tanabata}}", the [[AnachronicOrder season 1 episode "Mysterique Sign" that comes directly after]] makes references to the "Star Festival" instead.
* IndecisiveMedium: The Anime went out of its way not to show Kyon's mouth during his monologues, to keep the uncertainity from the novels, where you could never tell if he was saying something out loud, or just thinking.
* IndirectKiss:
** In ''Sigh'', Mikuru shows some rare outgoing qualities by offering Kyon a drink from a water bottle that she already drank from, and Haruhi grabs it before Kyon can. Subtextual meanings runs rampant among fans.
** A straight example at the end of the last episode of ''Sigh'', when they flashback to when Kyon talked to Haruhi at the cafe in May - Haruhi finishes Kyon's drink shortly before storming out.
** A better example in book 6 (with free bonus trope). Mikuru places her finger on Kyon's lips and then her own, in order to get him to [[ShutUpKiss stop talking]].
* {{Infodump}}:
** Lampshaded. Yuki, Mikuru and Itsuki lay these down on Kyon, who usually responds by pointing out that he doesn't understand, or just facepalming.
** Itsuki in particular ''loves'' these, and seems to take pleasure in cornering Kyon for a few pages' worth of exposition.
* InnerMonologue: Loves to edge on DidIJustSayThatOutLoud.
* InsignificantLittleBluePlanet: In ''Surprise'', Kyon demands that the aliens take their fights to the fringes of the galaxy. Kuyoh replies that ''they have''.
* InvisibleParents: There are some parental figures, like the various adults in the island episode, but none of the characters' actual parents are ever seen. Yuki, of course, has no parents (in the human sense anyway) and Mikuru's [[TimeTravel probably haven't been born yet]], but Haruhi and Kyon are implied to have parents...who never show up, (Kyon's mother is never directly seen or heard, but often referenced, and his dad is mentioned once) and never seem to say or do anything that affects the plot.
* InvokedTrope: {{Woobie}}, {{absurdly powerful student council}} and a few others.
* ItsAWonderfulPlot: [[spoiler: [[InvokedTrope Created]] by Yuki in [[TheMovie ''Disappearance'']]. [[SubvertedTrope Subverted]] in that the point wasn't to teach Kyon anything, she merely acknowledged the possibility that she could be wrong. She even went so far as to give everyone who could tell him what happened the flu. ]]
* ItAmusedMe: Arguably the reason Haruhi does anything.
