[[caption-width-right:300: {{Fanservice}}, [[LaserBlade Beam Sabres]], {{Stable Time Loop}}s, and the [[LoveDodecahedron Unsubtle Harem Plot]].]]

->''"Count the tropes! Save, collect, trade for swell prizes!"''

[[http://soulriders.net/brian/fanfic/kbdh/ Kyon: Big Damn Hero]] is the result of creating a crossover between ''LightNovel/HaruhiSuzumiya'' and ''Wiki/TVTropes''. It starts with an InMediasRes prologue and moving swiftly on to an [[AnachronicOrder Anachronic Arc]] before finally settling into as chronological an order as possible when a StableTimeLoop shows up every few chapters.

First featured on the [[FanficRecs/HaruhiSuzumiya Haruhi fanfic recommendations page]].

As for the plot, it started with Haruhi being told about her powers in order to save Nagato. Then came time travel, breaking up crime rings, a harem plot, [[VisualNovel/HigurashiWhenTheyCry Higurashi characters]] and a subplot involving a Slider and the Sky Canopy Dominion.

Is it worth mentioning that the series frequently mentions much of the cast being fans of the 'JustForFun/TropeTan anime'?

Consists of 13 arcs so far:
* Obligatory Anachronic Order Explanation (2 chapters)
* Straightforward Flashback and Exposition (3 chapters)
* Heroic Antics Begin (5 chapters)
* Filler (4 chapters)
* Fanservice (4 chapters)
* Gearing Up (5 chapters)
* Initial Conflict (5 chapters)
* Thwarted Lull (5 chapters)
* Calm Before The Storm (5 chapters)
* Storm Begins (5 chapters)
* Open Battle (7 chapters)
* Laying Low (6 chapters)
* Resolution (6 chapters)
* Alliances and Enemies (1 chapter and counting)

Due to negative reception on [[FanfictionDotNet Fanfiction.net]] (for his opinions, not his works) the [[http://soulriders.net/brian/fanfic/kbdh/ author's website]] will be the only source for new chapters. Chapters up to number 44 (Open Battle Arc, Chapter 1) can still be found [[http://www.fanfiction.net/s/5844698/1/Kyon_Big_Damn_Hero on Fanfiction.net]] (Warning: there will be '''no new updates there''').

[[foldercontrol]]

[[folder: A-C]]
[[#A]]
%% There is already an entry for the trope "One Hundred And Eight" for Tsuruya in the Characters' Page.
* AcceptableBreaksFromReality: Subverted. Kyon raised his PDA to take a picture of some police officers while invisible in Chapter 34. To his surprise, it made an audible click, because all cellphones and cameras are required to make a sound in Japan, ostensibly to make things harder for voyeurs. It nearly blew his cover.
** Played straight with the NPA, who act more like the United States FBI than the real NPA because it makes a better story.
* AcousticLicense: {{Averted|Trope}} in the FreefallRomance scene from Chapter 39. As it happens to skydivers and parachutists, it's normally impossible to speak to another person in such conditions. [[spoiler:Yuki bypassed this by touching his skinsuit and transmitting her voice through bone conduction.]]
* ActionPrologue: [[InMediasRes The]] [[DepartmentOfRedundancyDepartment prologue]].
* ActorAllusion: When discussing ''LuckyStar'' Taniguchi mentions that Konata's voice creeps him out for some reason--[[Creator/AyaHirano most likely because it's so similar to Haruhi's.]]
** Similarly, in "Epileptic Plot Tree", Haruhi bites the head off a chocolate cornet (whichever end that might be).
* AdaptationDecay: In-universe example. A BrokenBase of Trope-tan formed due to the second season of the anime adaptation because it diverged from the manga a lot, according to Haruhi in Chapter 32.
* ADayInTheLimelight: Magical Radiant Nonoko and Shamisen saves the Day in Chapter 47.
* AdultsAreUseless: Kyon's parents.
* AdultFear: Chapters 47-48 were a WhamEpisode for [[LockedOutOfTheLoop Kyon's parents]]:
** Akane was taking care of a feverish Nonoko who was hit by a cold and left her alone in her room for a few minutes. When she came back, Nonoko was nowhere to be found. When phone called later, she was told that the girl was in fact ''kidnapped''; however she was already rescued by her brother. This also applies to her husband Yuuto who was left in an HeroicBSOD by the news of his daughter missing until he was informed Nonoko was safe.
* AffectionateGestureToTheHead: Kyon tousles his little sister's hair pretty much whenever he sees her.
* AfterSchoolCleaningDuty
* AIIsACrapshoot: Kyon fears that his new PDA could become [[{{Terminator}} Skynet]] after Yuki said that it was capable of learning and that it was formed from remnants of [[KnifeNut Asakura Ryouko's data]]. However, this doesn't stop him from [[TemptingFate naming the device exactly that]].
* TheAllSolvingHammer: Tsuruya Kenshiro's approach to...pretty much any problem, really, is "buy the institution involved".
* AlienInvasion: In Michikyuu Kanae's backstory, it's the reason she started sliding through universes.
* AllGirlsWantBadBoys: [[spoiler:Kanae]] and several other nameless girls at the school while [[spoiler:Kyon]] happens to be in 'delinquent mode'.
** Mikuru, on the other hand, prefers [[SingleWomanSeeksGoodMan 'domestic mode']].
* AllPartOfTheShow: See BavarianFireDrill below.
* AllJustADream: Inverted in Chapter 30 with Kanae, who doesn't realize she was awake until [[spoiler:after she kisses Kyon]].
** Kyon and Sasaki experience a similar inversion in Chapter 60, [[spoiler:during their kiss]].
* AmazinglyEmbarrassingParents: {{Invoked|Trope}} by [[VisualNovel/HigurashiWhenTheyCry Keiichi and Rika]] and raised to an art form. From Chapter 61:
-->'''[[{{Miko}} Matsuri]]:''' O-oh, um, Kyon-nii-- For, um, for extra purification--\\
'''Rika:''' Matsu-chan, nothing about Watanagashi involves kissing. ''*blows a kiss to Keiichi*'' [[SayingSoundEffectsOutLoud Chu~]]\\
'''Matsuri:''' ''*[[LuminescentBlush blushing]]*'' I-- I wasn't-- I mean-- ''Mo~om''!\\
'''Keiichi:''' A direct hit!\\
'''[[GirlsHaveCooties Shutaro]]:''' No! My own father!\\
'''Keiichi:''' Arg… brain… turning to mush! Save yourselves!
* AmusingInjuries: Among other things, [[spoiler:Achakura]] has been drowned (by Yuki) and hit across the room (by Yuki) within two chapters. She is nothing more than data, so it's somewhat justified.
* AnachronicOrder: The [[ShapedLikeItself Anachronic Order Explanation arc]].
* AncestralWeapon: The hilt of Kyon's {{laserblade}} was used by one of his ancestors ([[spoiler:Usui Sadamitsu[=/=]Taira no Tadamichi]] to be precise).
* AndThatLittleGirlWasMe: [[spoiler:Shinobu, in Chapter 56.]]
* AndTheAdventureContinues: Due to [[AuthorExistenceFailure the story ending abrubtly]] after many of the main plot threads are resolved the ending has shades of this.
* AnswerCut: The ''InMediasRes [[DepartmentOfRedundancyDepartment Prologue]]'' includes, among other things, Kyon being attacked by Asakura Ryouko, having possession of a lot of supernatural tools his canon counterpart doesn't have and Haruhi not batting much of an eye to Kyon's admission Asakura is an humanoid interface like Yuki. At some point after that Kyon asks himself "It started off such a nice day, too. How had it come to this, anyway...?". Cue scene change to the first non-prologue scene. The storyline after this point then continues... 40+ chapters later.
* ARareSentence: In Chapter 57.
--> Ichiro raised a hand to his face and sighed. "My apologies for their behavior," he said, bowing his head. "Good help is hard to keep from being thrown away in a pointless attack on your ... fiance." What a strange thing to say!
* ArrangedMarriage: [[spoiler:Tsuruya and Kyon are set up on a ''omiai''[[note]]and end up engaged[[/note]]]] in Chapter 28. The marriage part of the trope is justified by the parents as beneficial because both families used to be extremely powerful a millennium ago. Disregarding that, also because both of them like the effect and skills the other parents' child has.
* ArsonMurderAndJaywalking: Kyon mentions casually to Sasaki that he has to meet several past instances of people, fight 12 thugs at once, arrange to deliver an alien artifact and study for a math test. It scares the crap out of adult Mikuru, [[SarcasticConfession but Sasaki doesn't take it seriously]].
* AscendedExtra: A few classmates of Haruhi and Kyon, background characters from the anime with barely a surname and a line of characterization to their credit in [[AllThereInTheManual the supplemental materials]] at the time, are given bigger roles here. Notable examples are [[http://haruhi.wikia.com/wiki/Sumire_Yanagimoto Yanagimoto]][[note]](canonically described as "Member of the Rhythmic Gymnastics Club. Dislike Haruhi.")[[/note]] and [[http://haruhi.wikia.com/wiki/Yamane Yamane]][[note]](canonically described as "Member of the Idol Research Club. Sniff Asakura's scent.")[[/note]].
* AugmentedReality: It's how the SOS Brigade can perceive and interact with [[spoiler:the chibified Asakura]].
** As part of her preparations, Mikuru was given an AugmentedReality system. It doesn't seem to interact very well when watching some movies.
** [[spoiler:This trope is taken to its logical conclusion in Chapter 61, where Achakura deploys a tactical AR environment for Kyon, providing him with real-time information about his enemies, targeting warning receiver, battleground condition updates, etc. The overlaying pseudo-holographic display is so effective that he can fight regardless of light condition and visual impediments like concealment (think of X-Ray Vision), smoke, blinding flashes, etc.]]
* AuthorCatchphrase: That suited them just fine.
[[#B]]
* BackToBackBadasses: Kyon and Yuki in Chapter 44. [[spoiler:The horde of Sumiyoshi-rengo they dismantled were less than pleased at this arrangement.]]
* BadassFamily: Haruhi is firmly convinced that Kyon's family is one. Readers have yet to see proof of the ''opposite''. To wit: his father is a Manga/InitialD-class BadassDriver and is apparently a descendant of the [[http://en.wikipedia.org/wiki/Taira_clan Taira clan]][[note]]The Taira were one of the four important clans that dominated Japanese politics during the Heian period (794-1185) -- the others were the Fujiwara, the Tachibana, and the Minamoto (from whom the Tsuruya family are descendants)[[/note]]; his mother is intimidating enough that the entire [[VisualNovel/HigurashiWhenTheyCry Higurashi cast]], possibly Mori and ''Haruhi'' herself, are very cautious of crossing her; and his little sister (when properly outfitted) can take apart [[spoiler:the Combine's synths]] with a giggle. Heck, even their ''cat'' gets a badass moment or two.
* BalancedHarem: [[spoiler:{{Invoked|Trope}}. The girls in the SOS-dan take great care to share equal time with Kyon, usually at Haruhi's or Tsuruya's urging.]]
* BatmanGambit:
** Kyon asks Koizumi to mail Haruhi when they are going to meet the Student Council President, so he may have just enough time [[spoiler:to talk with Kimidori Emiri about the IDSE's goals and reasons, but not to do anything before Haruhi shows up]]. [[MeaningfulEcho Works better than expected.]]
** Tsuruya pulled off a nifty one in Chapter 29. [[spoiler:After the surprise of her [[ArrangedMarriage engagement]] with Kyon, Tsuruya took in her hands how to deliver the news to Haruhi, which she did as soon as possible in a school day while reassuring Haruhi that she was in no way attempting to separate her and Kyon. That left Haruhi to mull over things during class (where she sits behind Kyon) and as soon as the classes were over, she dragged him to.. er.. allay her concerns on the matter. Predicting this, Tsuruya looked for them in any secluded location around school she could think of with the objective of assuring Kyon that everything was alright and, if she timed things right, giving him a "good-natured heart attack".]]
** Tsuruya arranged a similar one in Chapter 62. Predicting how hard would be for [[spoiler:Sasaki]] to deal with a paradigm shift such as [[spoiler:the confirmation of the supernatural]], Tsuruya made sure of keeping [[spoiler:a "supply of Kyon-kun"]] at hand. All said and done, it worked remarkably well.
* BavarianFireDrill: After [[spoiler:Kyon is shot and in retaliation Haruhi uses her MindOverMatter powers]], Haruhi simply acts as she were the Director of a movie to invoke AllPartOfTheShow. Bystanders start applauding.
* BeachEpisode: It starts in Chapter 30, and ends in the next chapter.
* BeamSpam: [[KillSat Gungnir]] can fire lasers at up to [[{{Cap}} 65,535]] targets at once.
* TheBeard: After rumor goes in Kitago about Kyon being engaged, most "unclaimed" girls of the SOS Brigade get one to prevent unwanted romantic attention: [[spoiler:Haruhi and Kanae have each other, and Mikuru has Shutaro ([[MasterOfDisguise a disguised Kyon]])]].
** Interestingly, it's implied that this trope was very much in effect until that point without anyone meaning to. The ambiguity of the relationship between Kyon and Haruhi, Yuki and Mikuru was apparently enough determent to keep their (many) suitors at bay.
* BeatThemAtTheirOwnGame: Believe it or not, [[spoiler:''Kanae'']] managed to reduce ''Haruhi'' to a blushing fit once with a RomanceInducingSmudge.
* BedmateReveal: Happens to Kyon when he wakes up one day just to find Kanae sleeping at his side. [[spoiler:Turns out that she teleported herself to his bed while sleeping after she learned to slide within the same world.]]
** Happens to Kyon again in Chapter 40. [[spoiler:With a twist. This time, Kanae teleported herself to his bed on purpose, but after she woke up she discovered that Yuki had the same idea.]]
** Happens once again in Chapter 47, [[spoiler:only this time with Haruhi and Tsuruya, thanks to Yuki and Kanae teleporting them there.]]
** At this point it's pretty safe to assume they ''will'' [[InvokedTrope invoke]] this trope every time they can get away with it. They even were GenreSavvy enough to get a [[MagicFromTechnology special program]] in place that teleports the girls [[spoiler:(except for Achakura; she is invisible after all)]] out of Kyon's bedroom the instant someone tries to open the door, in clear {{defi|edTrope}}ance of a [[ParentsWalkInAtTheWorstTime certain problematic trope]].
* BerserkButton:
** Do not [[spoiler:try and harm any of Kyon's friends, let alone push Tsuruya out of a window. He will suspend you by the ankle with one hand and invoke DissonantSerenity.]]
** In a similar vein, do not [[spoiler:shoot Kyon. Haruhi will gladly try to kill you.]]
* BetterThanABareBulb: Given the ridiculous number of [[LampshadeHanging Lampshades hung]] over the course of every chapter, it's safe to say this is in effect.
* BifurcatedWeapon: [[MorphWeapon Altair + Vega]] + [[{{Laserblade}} Hakurouken]] = [[KillSat Gungnir]].
* BigBrotherInstinct:
** Threaten Kanae like Ryuguu did, and Kyon will come after you with a vengeance. In fact, he'd fix up most problems in the Brigade, mostly with force because of circumstances.
** Don't even insinuate that you will harm any of his friends in front of Kyon. He will practically ''teleport'' in front of you.
* BigDamnHeroes: Right there in the title. And in the prologue. Also happened at some other point, we finally get to see over twenty chapters after we first learned about it.
* BigNo[=/=]LittleNo: Both played for laughs when Mikuru wants to meet Kyon (who was busy [[spoiler:giving Haruhi a [[PostKissCatatonia catatonia-inducing kiss]]]]) because he could help Koizumi with some "esper business", as he put it. As both Yuki and Koizumi are connected to Haruhi and feel her emotional state, both voice their negative accordingly:
-->"Oh, my," Mikuru said, frowning as she glanced around. "Um ... should I call Kyon-kun about it?"\\
"No!" Koizumi barked, almost shouting\\
At the same time Yuki raised her gaze from her book and said, much more calmly, "No."
* BirthdayEpisode: The first quarter of Chapter 61 is devoted to the SurpriseParty that the girls prepared for Kyon.
* BiTheWay: Any doubts about Haruhi [[spoiler:and Tsuruya]] are removed in chapter 54.
* BlahBlahBlah: In Chapter 1.
-->'''Haruhi:''' Blah blah blah, Skip the speeches - if I don't know the complete back story, it's all meaningless to me.
* BorrowedCatchphrase: Chapter 61:
-->"We can [[FriendlyTickleTorture tickle it out of her]]," Mion suggested, eyeing the shrine maiden sternly.\\
"Hau..." Rika whimpered, backing cautiously away.
* BreadEggsMilkSquick: After [[YakuzaPrincess Tsuruya]] comments to Haruhi that she learned calligraphy because it's an important thing to know in the business:
-->'''Haruhi:''' What else did you learn? Back to the beginning... I know you mentioned that you had some martial arts training, too?\\
'''Tsuruya:''' All proper things! Tea ceremony, calligraphy, social behaviors, ninkyo dantai formality, martial arts, interrogations ... that kinds of stuff.
* BrickJoke:
** Kyon's analogy in the prologue for being hit by Ryouko is about being hit by a speeding minivan. Guess what happened in the Initial Conflict arc.
** Also used in conjunction with the StealthPun in Heroic Antics Begin Arc, Chapter 4, which is titled: [[UpToEleven Chapter Eleven]]: ''Yes, It Goes There [=/=] Yeah, It Went There'' (depending on whether you're looking at the Table of Contents or the chapter itself). If you recall, the title for Chapter 3 is called: Chapter Three: ''It Goes To Eleven''.
** [[spoiler:In Chapter 9, Kyon's father tells him, "There's no way you could come home from school one day and announce that you had, say, rescued an heiress from rampant hoodlums and secured a position at her father's company. So, (your mother's) point of view is that there's no future in fighting." Naturally, this is exactly what ends up happening.]]
** After 37 chapters going unmentioned, Yuki offhandedly reveals that she always knew of the small "private library" that Kyon keeps in his cell phone (see "PornStash" below) and notifies him that she will keep it ''updated''. Kyon apparently doesn't check it too often because her words seemed to miss the target. Tsuruya, on the other hand, had to bite back a smirk.
** In Chapter 3, Haruhi uses her recently discovered powers to make her hair grow five times faster than normal. Finally, in Chapter 62 and a little more than two months later InUniverse, she managed to don a ponytail in class. Kyon predictably approved the new hairstyle.
** Yamane's seat in class remains unoccupied until a NewTransferStudent arrives in Chapter 62.
** In Chapter 11 and thanks to [[OneDialogueTwoConversations ambivalent semantics]], Mori mistakenly thought Kyon was having unprotected sex with Tsuruya and Yuki and made an adamant point to provide him with a box full of (as they put it) "protection". Much later in Chapter 63 and somewhat concerned after learning just how many girls Kyon's romantically involved with, Mori asked him how much "protective gear" he had left. Cue blushing, sputtering mortification.
** Chapter 63 marks the return of two additional bricks: Kyon mentioning the JustForFun/TropeTan outfit he briefly wore in Chapter 36 ([[ShuttingUpNow only to immediately regret it]]) and Tsuruya remembering her promise from Chapter 14 to Haruhi about not bathing with Kyon without her ([[LoopholeAbuse only for Yuki to suggest an alternative]]).
* BroFist: Between Keiichi and Satoshi in Chapter 17.
* BrokenMasquerade: Kyon pulls this on Haruhi so she can save Yuki. Also, that chapter's FictionalDocument refers to how to prepare for this trope as well.
* BuffySpeak: To avoid mentioning exactly what it was that he and Yuki swiped from Yamane Jun's room [[spoiler:(i.e. Asakura's gym shorts)]], Kyon [[VerbalBackspace stops himself halfway through the word]] and calls it "the corrupted data thingy."
* BusmansHoliday: The SOS Brigade visits Hinamizawa for [[FestivalEpisode Watanagashi]] and some well-earned R&R. No prize for guessing when [[spoiler:Wataru]] decided to show up.
* BystanderSyndrome: Pretty much any public act of violence seems to be accompanied by this.
** When Kanae is attacked by Ryuguu in a crowded school hallway, nobody tries to help until Kyon stumbles across them. He calls the other students on this.
** When Tsuruya and Kasai are attacked by Sumiyoshi-rengo, Tsuruya's narration notes that bystanders quickly streamed away, pretending nothing was happening.
** When [[spoiler:Sasaki]] is kidnapped in Chapter 52, her cries for help go ignored by onlookers.
[[#C]]
* CallingYourAttacks: ''Master Spa~ark!''
* CampbellCountry: Hinamizawa.
* CaptivityHarmonica: One of the inmates has one when Kyon visits Masao in jail. They use it to drown out their conversation in case of eavesdroppers.
* CassandraTruth: Kyon's sister frequently has tried to tell her parents and friends that her brother is a hero but nobody believes her. In part this is also because [[GenreSavvy Kyon]] [[InvokedTrope tells her enough to know but not enough for her to be believed if she tells someone else]].
** Sasaki doesn't believe in aliens, time travelers, espers, or sliders and recently convinced herself that they're code words used by Yakuza.
* CasualDangerDialog: Kyon, as a DeadpanSnarker, is prone to type 4. Of course, since he often already knows the outcome of the fight, he might not need to be worried.
* CatchPhrase Koizumi gets: "Somehow, that suited him just fine."
* CelebrityParadox: In addition to this wiki apparently existing in the fic's universe, Taniguchi mentions LuckyStar in Chapter 33.
* ChainedHeat: [[spoiler:Haruhi and Sasaki were handcuffed together by their kidnappers at the end of Chapter 54]].
* ChekhovsGun:
** Yuki checks out Kyon's wristwatch. A few chapters later, [[spoiler:it turns out she installed a program to create a impenetrable skinsuit in case Kyon gets attacked.]]
** During Haruhi's second time in Closed Space with Kyon, she made several unmentioned changes to reality, including a limit to her powers. A notable one showing up later is [[spoiler:removing Koizumi's limitations so that he can use his [=ESPer=] powers outside of closed space]].
** What about Chekhov's Coat?
* ChekhovsGunman: [[spoiler:Shamisen]], seriously. To be precise, [[spoiler:the "paragenetic silicon-based data lifeforms", who are hosted in Shamisen's body since the events of the short story ''Wandering Shadow'',]] helped [[spoiler:Kuyou]] out of a difficult situation in Chapter 47.
* ChunkySalsaRule: The enemy slider from Chapter 30 may not understand fighting very well, but he knows that threatening to reduce Kyon into a chunky salsa is the same as a death threat.
* CliffHanger: Frequently; Chapters 47, 53, 54
* CloseCallHaircut: Immediately after [[spoiler:[[MagicalGirl Radiant Magical]] Nonoko]] protests having to return Kyon's gear to him, citing that she's "[[Anime/PuellaMagiMadokaMagica not afraid of]] ''[[Anime/PuellaMagiMadokaMagica anything]]'' [[Anime/PuellaMagiMadokaMagica anymore]]", a flechette nearly [[OffWithHerHead beheads her]], only taking a few strands of hair instead.
* CombatAndSupport: After [[EmpoweredBadassNormal he got]] [[AppliedPhlebotinum his tools]], Kyon does the heavy-lifting and [[spoiler:Achakura]] handles the tech. [[spoiler:Later, Kuyou acquires her chibi-mode and takes a support role for him too, among other things, granting the team with access to her PhantomZone where the fighting can take place without the risk of collateral damage.]]
* CombatByChampion: Defied after the battle against the 24 {{Yakuza}}. Fujiya Masao, their boss who proposed himself as his own champion was convinced he doesn't have to keep fighting (and losing); instead, he only had to promise never work again with pictures of changing high school female students.
* ComicallyMissingThePoint:
** In Chapter 23 when returning from training Kyon was received with a pillow thrown to his face, making him fall. This conversation followed:
--->'''Kyon:''' Haruhi? Was that you?\\
'''Haruhi:''' Wah! Seriously? You can tell it's me because of how the pillow hit you?\\
'''Kyon:''' I can tell it's you because you hit me with a pillow at all.
** In Chapter 61, [[spoiler:Kyon comments that he agrees with the sentiment that they should take things slowly in their very complex romantic relationship, to "be a bit more restrained, just now". Kuyou remarks on the word "restrained" and notices that, with Sasaki and herself [[ALadyOnEachArm holding each of his arms]], he can't easily fend off if either of them tries to kiss him. Cue three-way make-out session.]]
* CommonalityConnection:
** It's eventually revealed that one of the reasons why Sasaki and Kyon got along so well in middle school is because of [[MyBelovedSmother how similar their mothers are]].
** [[spoiler:Their similar experiences as [=ESPers=] [[PsychicLink linked]] 24/7 to someone else's emotional state allowed Koizumi and Kyouko to truly empathize with each other.]]
* {{Continuation}}.
** ''Kyon: Big Damn Hero'' was first published during the three-years long ScheduleSlip after the ''[[LightNovel/HaruhiSuzumiya Dissociation of Haruhi Suzumiya]]'' and, while {{retcon}}ning it a little, it mostly works around what the reader knew until that point and picks up the plot after the first chapter of the ninth novel. After the ''Astonishment of Haruhi Suzumiya'' came up, the story became an AlternateUniverseFic proper.
** The fic also serves as a DistantEpilogue of sorts for ''VisualNovel/HigurashiWhenTheyCry'', retaking the events almost thirty years after the GoldenEnding.
* ContinuityCameo: It seems that [[spoiler:Kyon and Kanae]] made a brief but intriguing appearance in the seventh chapter of [[http://soulriders.net/brian/fanfic/later/ Later]], another one of Durandall's fanfics, in front of [[spoiler:the adult version of Kyon]], who reacts in a [[GenreSavvy savvy]] and [[OlderAndWiser very sensible]] [[JustIgnoreIt way]].
-->'''[[spoiler:adult!Kyon]]:''' [[spoiler:I suppose it's none of my business, whatever it was. Perhaps there's something strange and amazing there ... but as I've learned, there's no reason - really - to search for it. If I have to be involved, I'm confident that whatever is to happen will find me. And, really ... it doesn't bother me too much if it doesn't.]]
* ContinuityNod:
** Kyon receives a wristwatch from adult!Mikuru in Chapter 8, a model similar to the radio-controlled timepiece that young!Mikuru wears in ''Bamboo Leaf Rhapsody''.
** In Chapter 21, Haruhi congratulates Mikuru on being the first to accomplish her {{Tanabata}} wishes.
** Also, Koizumi explains his Esper powers over a cup of coffee with Haruhi, just like how he explained it to Kyon.
** At Tsuruya's house in Chapter 36, Koizumi reminded Kyon of the events of the [[AudioAdaptation Drama CD]], where Haruhi wrote a literal EarWorm and Hare Hare Yukai. Then they perform Hare Hare Yukai for everybody.
*** The Drama CD is also the source of Yuki's seldom-used [[spoiler:yet inhibition-eroding when used by Kyon]] pet name, "Yuki-rin".
** In the HeroesGoneFishing scene in Chapter 18, Keiichi warned Kyon to not go near a abandoned quarry. That's a reference to "[[VisualNovel/HigurashiWhenTheyCry Nekogoroshi-hen]]" (Cat Killing Chapter), a [[BonusEpisode single episode scenario]] of the anime based on the homonymous LightNovel.
*** Around the same point it was mentioned that Kyon and his cousins visited the same water park from "[[PoolEpisode Hajisarashi-hen]]", the first episode of ''VisualNovel/HigurashiWhenTheyCry [[OriginalVideoAnimation Rei]]''.
** Also in Chapter 18, Rika told [[spoiler:Haruhi]] about the "magatama incident" from ''[[VisualNovel/HigurashiWhenTheyCry Higurashi]] [[GaidenGame Daybreak]]'', or more precisely the episode of the same name from ''[[OriginalVideoAnimation Rei]]'' based on it.
** It has been mentioned a few times that Kyon resembles his grandfather a lot, which could be a small nod to [[http://haruhi.wikia.com/wiki/Myst%C3%A9rique_Sign_Returns "Mystérique Sign Returns"]]. This manga-only chapter features a case similar to the Cave Cricket incident, but in this case the data entity took the form of a man dressed in an Imperial Japanese Army uniform with a katana, who Kyon first mistook for an older version of himself. Later he discovered that the apparition was in fact based on her grandfather in his younger days.
** Most times Kyon has to time travel he notes how he is getting more used to it.
** In Chapter 50, Koizumi reveals that the fake version of Kyon who visited his room in ''Snow Mountain Syndrome'' was behaving aggressively in [[{{Seme}} 'that way']].
** It's implied that Yuki made her hair grow long via data manipulation to better resemble [[http://en.touhouwiki.net/wiki/Patchouli_Knowledge this character]] for the FlashMob in Chapter 53, which could be a reference to [[http://img710.imageshack.us/img710/5944/tomadoiyuki.jpg certain scene]] from the {{PS2}} game [[http://haruhi.wikia.com/wiki/The_Perplexity_of_Haruhi_Suzumiya Suzumiya Haruhi no Tomadoi]].
** In Chapter 59, Kyon's cousins commented that they play ''Old Man/Geezer'' (ジジ抜き, jijinuki) instead of ''Old Maid'' (ババ抜き, babanuki). This is a reference to an important conversation with TheBigBad by the end of [[GoldenEnding Matsuribayashi]][[VisualNovel/HigurashiWhenTheyCry -hen]], where both card games were used as part of an analogy.
* ContrivedCoincidence: The IDSE created tools for theoretical interactions with [[AlternateUniverse Alternate Universes]], with a dimensional anchor being among those items. The last one created dates from millions of years. The item found in Tsuruya's backyard during the seventh book? Guess what it is.
* ConversationalTroping: In Kyon and Sasaki's backstory it was the usual topic of conversation: Kyon presented a trope and Sasaki [[{{Deconstruction}} deconstructed it]].
* CooldownHug: This trope is used fairly often, like when Haruhi hugs Tsuruya when she blames herself for [[spoiler:Kyon being shot]], Yuki receiving one from Kyon when she is scared after being too close to a black hole, or Kyon being hugged after being dangerously close to killing, or when he visibly stressed from the fight against the Combine at Kitago ([[spoiler:after his sister joined the battle]]).
* CoolSword: Kyon's {{Laserblade}}, whose hilt was used by [[AncestralWeapon one of his ancestors]] and blade was made of the remains of a robot from another world.
* CoverInnocentEyesAndEars: In Chapter 60, Mikuru covers Kanae's eyes when [[spoiler:Kyon and Sasaki kiss for the first time]]. She quickly realizes it was kind of pointless as Kanae [[spoiler:had already kissed Kyon on her own.]]
* CovertPervert:
** It seems neither Kyon nor Mikuru missed the potential implications of him getting carte blanche from her superiors:
--->"Okay. Asahina-san, I know I requested your superiors back me up on explaining who you are to Haruhi, but I'm still not clear on why they suddenly decided that it was okay for you to do ... whatever I said," Kyon said, shifting his shoulders. "Was there anything else in that message?"\\
"Um, no," she answered, her face turning pink, her eyes looking away.
** [[spoiler:Yuki and [[VisualNovel/HigurashiWhenTheyCry Hanyuu]].]] They spent their time in Hinamizawa together "enjoying the view" of Kyon in bath.
** When Kyon and five girls from the SOS Brigade disappeared from Mion's house for some training in Yuki's PocketDimension in Chapter 59, [[spoiler:Hanyuu]] immediately arrived to the conclusion that they went somewhere to do "naughty things". Apparently, she knows for a fact that Rika and the others did the same thing all the time when they were that age.
** As surprised as she was at Haruhi's InnocentInnuendo in Chapter 63, [[spoiler:Sasaki]] was coming to terms with the idea of [[spoiler:sleeping with Kyon]] remarkably quickly before Haruhi corrected herself.
* CowerPower: After Haruhi's reaction to Tsuruya's report on what she and Kyon did to disband a illegal photographic ring (which included sleeping and bathing together -- ItMakesSenseInContext), Mikuru automatically hides behind Tsuruya. Kanae, noting that Tsuruya isn't the safest cover in this circumstance, decides not to follow this trope and only hide behind the table.
* {{Crackfic}}: It crosses over with ''tropes''. It should also be noted that nobody knows how to cross a story with a concept.
* CreatorCameo: In Chapter 50, during the conversation where Haruhi and Kyon discussed how to name his LaserBlade, she suggested the name of the "weapon from the battle of Troy, and featured in the [[Literature/TheSongOfRoland 'Song Of Roland']]". Kyon rejected it because "somehow, [[StockWeaponNames that particular name felt overused]]".
%% Crowning moments go on their own pages %%
* CurbStompBattle:
** Kyon, Yuki, and Tsuruya, vs. 24 Yakuza. [[BlatantLies Poor Yakuza.]]
** Once more in the Initial Conflict arc. [[spoiler:You know the twelve {{Yakuza}} he beat on that Sunday? He defeated them all spectacularly easily.]]
* CurseCutShort:
** Kyon's first meeting with Ryuguu in Chapter 6. Kyon smashed his nose against the equipment shed, making him curse. Before Ryuguu could finish [[PrecisionFStrike the curse]], Kyon smashed his nose in again.
** On second thoughts, search for any mention of "fu-". That's a CurseCutShort. For example, Chapter 7, when Kyon's ''sternly chastising'' Watanabe.
* CutenessOverload:
** Mikuru when Kyon first calls her by her first name. [[spoiler:As a result, she kisses Kyon with utmost desperation [[HypocriticalHumor while giving the "it's forbidden" speech]].]]
** Also happens to Haruhi when [[FirstNameBasis Kanae first calls her Suzumiya-sempai]].
--->'''Mikuru:''' Eh? Suzumiya-san? Are you alright? You look dazed!\\
'''Haruhi (in a faint voice):''' S...something amazing happened.
** And to Yuki, of all people, when [[spoiler:Kyon calls her ''[[ContinuityNod Yuki-rin]]'']].
** A notable instance that doubles as a minor plot point takes place in Chapter 63. Kuyou, donning an unbelievably adorable variant of her [[FunSize chibi-mode]], manages to [[spoiler:completely bypass Sasaki's disbelief-activated PowerNullifier by virtue of being ''[[RuleOfCute just too cute for Sasaki]] [[WillingSuspensionOfDisbelief to stop to think if it makes sense or not]]''. Once realization hit and incapable of doubting her own eyes, Sasaki had no further troubles to accept Yuki's explanations about the AugmentedReality system that the SOS Brigade uses, from then and on preventing her power from interfering with it.]]
*** And then she notices [[spoiler:Achakura]]...
---->Ah! Cute!
[[/folder]]

[[folder: D-F]]
[[#D]]
* DangerouslyGenreSavvy: After Kyon fired a [[spoiler:[[MagneticWeapons rail-]][[KineticWeaponsAreJustBetter accelerated needle]]]] to OneHitKill a [[spoiler:Strider]] in Chapter 61, the rest of them [[spoiler:recalibrated their DeflectorShields]] to prevent this from happening again. [[spoiler:Ultimately a {{subver|tedTrope}}sion, because this allowed Kyon to run to the closest one and chop it into pieces with ''[[LaserBlade Hakurouken]]''.]]
* DashAttack: In an interesting combined application of his LaserBlade, DeflectorShields and [[GravityMaster gravity manipulators]], Kyon in Chapter 61 set "the field below him to frictionless", shot himself towards the nearest enemy and cut it in half with ''Hakurouken'' as he dashed beneath it. A highly difficult technique and Kyon himself guessed that merely training his reflexes to deal with the lack of resistance transferred from the sword to the wielder must have took Yuki a lot of work.
* DaydreamSurprise: In Chapter 31, Kanae daydreams herself in a BeachKiss scene with Kyon, apparently a {{Recurring Dream|s}} of hers that usually doubles as a ShirtlessScene[[spoiler:, which turns to be a subversion of the ThatWasNotADream type.]]
* DeadManSwitch: Sasaki [[InvokedTrope invokes this trope]] in Chapter 37. It goes like this: if she doesn't send two text messages at certain times of the day, the intended recipient will know that something bad happened to her.
* DefiledForever: {{Parodied|Trope}} in Chapter 60, just after Kyon kisses [[spoiler:Sasaki]]:
-->Haruhi snorted. "Yeah, well, now you've ruined her for marriage," she warned.\\
"What!?"\\
"Ah, n-no, I--" [[spoiler:Sasaki]] began, before Haruhi covered her mouth.\\
"Utterly ruined!" Tsuruya agreed. "You'd better promise to take care of her!"\\
"But-- But--" Kyon started to protest.
* DeflectorShields:
** Kyon's coat has them, but they're very complicated to operate and very energy-consuming under heavy fire or when he uses them for more telekinesis-like applications. [[spoiler:Their practicability was greatly improved after Achakura took charge of most of their micromanagement.]]
** In a pinch, [[spoiler:Haruhi]] can use her powers to improvise a temporal force shield sturdy enough to resist [[spoiler:direct fire from a Strider's wrap cannon.]]
** [[spoiler:Slider!Kuyou]] used some sort of green PureEnergy construct to [[spoiler:protect Wataru from enemy fire and to slow down his fall à la ''Franchise/GreenLantern''.]]
* [[DeniedFoodAsPunishment Denied Lunch As Punishment]]: To Kyon when he's grounded.
* DenyingTheAntecedent: Kyon's sister resorted to this to get herself invited to the [[BeachEpisode beach trip]] in Chapter 29. Kyon immediately noticed it, but it turns out that she goes anyway.
-->'''Kyon:''' So ''if'' I tell you, that means you can't go. Understand?\\
'''Kyon's sister:''' Okay! So, don't tell me! That means I can go!\\
'''Kyon:''' That's not what--
* DestinationDefenestration: Yamane does this to Tsuruya when he's cornered by her, Kyon, Yuki and Yanagimoto in the photography club room. Kyon managed to pick her hand before falling though, and between him and Yuki they picked up Tsuruya back in the clubroom.
* DiggingYourselfDeeper: Taniguchi in Chapter 56. It has to be seen to be believed.
* DisappearedDad: [[spoiler:Sasaki's father.]] Her mother's bitterness at the abandonment strongly implies that this is ''not'' a case of DaddyHadAGoodReasonForAbandoningYou.
* DiscardAndDraw: After her disconnection from the IDSE, Yuki lost access to the Entity's assistance and resources, which severely limited her effectiveness to detect and deal with the threats that could affect her protection targets[[note]]this is part of the reason why Kyon had to TakeALevelInBadass and handle some measure of danger by himself[[/note]]. To compensate this, Yuki now makes a point to [[AwesomenessByAnalysis analyze and reverse-engineer]] any new supernatural power available for her study in order to [[PowerCopying enhance her abilities' library]]. [[spoiler:So far Yuki has learned {{teleportation}} from Kanae, the ability to create a PocketDimension from Haruhi, a [[PerceptionFilter specific kind of invisibility]] from Kuyou and she also adapted Mikuru's AugmentedReality technology for the SOS Brigade's usage.]]
* DiscussedTrope: Quite frequently. Some notables examples are:
** In Chapter 4, Haruhi complained about DeathOfTheHypotenuse. [[spoiler:It gets bonus points because her dislike of mediocre romantic resolutions is a plot point.]]
--->'''Haruhi:''' I don't like that answer. It's just like an action movie where the hero dies. Or where the hero likes two girls, so one isn't quite as pure-hearted or kind as the other, and is killed to make it so the hero never has to choose.
** Surprisingly enough, Kyon and Haruhi discussed {{Tsundere}} in Chapter 5 with interesting results:
--->'''Kyon:''' "I did say that, but I don't know what 'tsundere' means."\\
'''Haruhi:''' "Stereotypical anime relationship? [[BelligerentSexualTension Girl likes boy, boy likes girl? Girl hits boy, boy mouths off to girl?]] You could change the order of operation, but it all works out the same."\\
'''Kyon:''' ""[[{{Deconstruction}} Oh ... well, that's not a real relationship]], [[EnforcedTrope just a mechanic to let the viewers know that a relationship exists while artificially keeping it from developing]], [[TokenRomance since it's a minor point at best in the role of the show]]. (...)"
** Kyon once discussed ThoseTwoGuys with [[ThoseTwoGuys Taniguchi and Kunikida]] after school in Chapter 13. To wit: each of them claims that he's the real main character and that the other two are ThoseTwoGuys.
** Mikuru, Koizumi and Haruhi discuss ObliviousToLove in front of [[ObliviousToLove Kyon]] in Chapter 24. He doesn't get the hint.
** In Chapter 63, part of the SOS Brigade talked about [[TeleportInterdiction counter-measures against teleportation]]. [[GenreSavvy Kyon]] [[CombatPragmatist immediately]] suggested to set the exit point of an enemy portal [[HurlItIntoTheSun inside the sun]].
* DistractedByTheSexy: Nagato and Hanyuu stopped fighting because Kyon got out of the bath.
* DistressedDamsel: Sasaki has been kidnapped four times and Haruhi once (due to a played with instance of BruceWayneHeldHostage due to [[spoiler:Sasaki's disbelief based PowerNullifier abilities]]).
* DoesNotKnowHisOwnStrength: In Chapter 35's FictionalDocument, it warns you to be careful of one's new powers.
* DoesThisRemindYouOfAnything:
** This excerpt from Chapter 54:
--->"Um ... I'm sorry about this...." [Kyon] paused, considering, then winced and asked, "Did it ... hurt?"\\
"Not as much as the first time," [Haruhi] groaned, lowering her hands before blinking and suddenly looking to one side. "Um-- It's fine, really...."
** Sometimes Yuki's narration is kind of eyebrow-raising. From Chapter 56:
--->It would be nice to join in on that, but Yuki was enjoying herself at the present, and could enjoy some further time with Kyon once he got back home and went to bed.
** Or earlier, in Chapter 43:
--->It was strangely intimate, with [[spoiler:Kuyou]] submitting entirely to Yuki's manipulations, and Yuki -- for her part -- proceeding as cautiously as possible, not wanting in any way to damage the other entity.
* {{Doorstopper}}: As of Chapter 59, the story is approximately as long as the English translation of memetic doorstopper ''Literature/WarAndPeace''[[note]]both of them have a word count of around 587,000 words[[/note]].
* DramaticIrony: Used for comedy with the "very special hell" RunningGag. [[spoiler:Kyon has had make out sessions with Haruhi, Yuki, Tsuruya, Mikuru and Kanae, and as a result he's troubled because he thinks he's cheating Haruhi even if they aren't even dating. His ArrangedMarriage with Tsuruya doesn't help. He doesn't know that all the girls agreed [[MarryThemAll to share him]]]].
* DrivesLikeCrazy: Kyon's father drives "[[InsistentTerminology efficiently]]."
* DroppingTheBombshell:
** Haruhi and Tsuruya are chatting about [[spoiler:Kyon and kissing]] in the presence of Yuki, who was silently reading:
--->'''Tsuruya:''' [[spoiler:Would kissing be within those boundaries?]]\\
'''Haruhi:''' I already did, so I'd be a hypocrite if I said no.\\
'''Tsuruya:''' So he practiced with you! That's why he was so good .... Er.... Um....Um, I have a picture of me in a [[CostumePorn junihitoe]] on that SD card!\\
'''Haruhi:''' You and him!? Er.... I mean.... Yeah, he's really ''really'' good, isn't he?\\
'''Tsuruya:''' I thinks so.\\
'''Yuki:''' I also think so.
*** Why it's an example? Because it made Haruhi and Tsuruya realize that [[spoiler:Yuki and Kyon being in a nightly YearInsideHourOutside training for weeks gave Yuki the chance of being kissed by Kyon many times before and made him become the excellent make-out partner, even if [[LaserGuidedAmnesia he can't remember it afterwards]]]].
** [[spoiler:Tsuruya-sama, [[{{Yakuza}} ninkyo dantai]] boss,]] drops a bombshell so huge by revealing Kyon's relationship with his organization and the deeds Kyon has done for it that Kyon's mother faints from the shock.
** When Kyon was asked, in front of the whole 2-5 class, if he was engaged to [[spoiler:Tsuruya. By Kunikida]].
** Happens to Sasaki in chapter 62 [[spoiler:when the SOS brigade prove to her that [[HumanAliens Aliens]], [[PsychicPowers ESPers]], and [[TimeTravel Time Travelers]] are all real, she has PowerNullifier abilities, and that she creates spaces and bestowed powers onto people like [[RealityWarper Haruhi]] does. She decides that {{Fainting}} in Kyon's lap is the proper thing to do.]]
* TheDutifulDaughter: Tsuruya's mother in the backstory in contrast to her sister[[spoiler:, Shinobu.]]
* DynamicEntry: One of the fictional documents advise this. In addition, [[spoiler:Kyon used it on one of the twelve {{Yakuza}}.]]
[[#E]]
* ElectricSlide: When Kyon wanted to get from his school to the meeting point with Future!Mikuru in Chapter 42, he performed this trope. [[spoiler:Ryouko Asakura]] found it interesting but quite inferior compared to teleportation.
* ElegantGothicLolita:
** One of Tsuruya's costumes. Though admittedly, [[PerkyGoth her cheerful demeanor doesn't complement it well]].
** In Chapter 33, Yuki gets her costume, and she pulls it off quite well.
* {{EMP}}: One of the [[MorphWeapon known presets]] for Kyon's guns fires a directed and fairly localized electromagnetic pulse. Used in two occasions to stop a car in its tracks.
* EmpathicWeapon: When Kyon genetically imprints [[spoiler:his new weapon, courtesy of future Kyon]], he feels a highly disconcerting awareness of the weapon.
* EntertaininglyWrong: Due to her rational nature, Sasaki tends to get hit by this trope fairly often. For example, after witnessing Kyon's proficiency as a martial artist Sasaki accurately deduces that he must have trained for years to reach that level of skill; but she makes the reasonable yet incorrect assumption he knew how to fight when they met in middle school and remained quiet about because he's not the type to brag.
* EstablishingCharacterMoment: Kyon's sister gets hers in Chapter 13 when Kyon tells her about his heroic antics. It really shows how much she cares for her brother and is afraid of losing him, as it's the first time [[SwitchingPOV the story is told from her perspective]].
* EveryoneIsBi: Thus far the only one of Kyon's girlfriends not to have made out with at least one other of Kyon's girlfriends is Mikuru.
** Now that she's part of the harem, Kuyou is another exception. [[spoiler:And as of Chapter 60, Sasaki's been added to the group.]]
*** Kuyou's connection to Kyon's PDA by Yuki was described... As a very intimate process. Might count, for beings like Yuki and Kuyou.
* ExactlyWhatItSaysOnTheTin:
** Guess what the InMediasRes prologue was named?
** Most arc names are like this too (Heroic Antics Begin includes the first time Kyon is shown being "hero", in Gearing Up there's new equipment and so on) with the exception of, ironically, the {{Filler}} and {{Fanservice}} arcs.
* ExcaliburInTheRust: Kyon's AncestralWeapon. Subverted in that it actually ''is'' in a state of disrepair and data manipulation is needed to make it a functional weapon. Of course, it probably wasn't a LaserBlade in its original incarnation...
[[#F]]
* {{Facepalm}}: Haruhi when she realized Kyon will get in trouble with the Student Council again [[spoiler:by dangling Yamane out a window.]]
* {{Fainting}}:
** Kyon's mother's reaction upon learning what really is the Tsuruya family business.
** "If you do not mind, I would like to faint now." Is Sasaki's (quite polite) reaction in Chapter 62 to [[spoiler:finding out and having it proven to her that Aliens, [=ESPers=], and Time Travelers are all real]].
* {{Fanservice}}: Constantly played straight, and subverted in the actual 'fanservice arc'.
** More like constantly [[InvokedTrope invoked]]. With fanservice played straight, there's often no particular in-story reason why it's there, and the characters themselves aren't aware of it. Here, the fact that there ''will be'' fanservice is so well established that nobody even questions it anymore; the remaining issue is ''who'' gets to do it.
* FanservicePack: Haruhi wishes for one in Chapter 2.
* FascinatingEyebrow: Part of Kyon's answer to Fujiwara's declaration of not giving up the [[SwissArmyWeapon slider's weapon]] to him. The other part was Kyon showing Fujiwara the very same weapon, meaning it's a [[StableTimeLoop predetermined event]] Kyon will receive it.
* FestivalEpisode: [[VisualNovel/HigurashiWhenTheyCry Watanagashi]] in Chapter 61.
* FictionalDocument: The [[{{Epigraph}} beginning of every chapter]]. Mostly EncyclopediaExposita-like self-help books on being a hero, with the occasional poetry thrown in. They're implied to be from future documents/books. Since the author never [[WordOfGod said who wrote what]], it will remain an extremely popular topic in [[WMG/KyonBigDamnHero the WMG]].
* {{Filler}}: Subverted in the so-called FillerArc.
* FirstEpisodeSpoiler: The IDSE scheduling Yuki's deletion, forcing Kyon to use his TrustPassword on Haruhi thus making her be aware of her powers.
* FirstGirlWins: Haruhi calls it a cliché, since she believes that one can always fix the situation, as in Sakanaka's case.
* FirstNameBasis: At the same time that the SOS Brigade strengthens their TrueCompanions relationship, characters start addressing others differently:
** Kyon refers to Tsuruya by ''Tsuruya-san'' the first time she sees him fight (as he does in {{Canon}}), then ''Tsuruya-sempai'' after that fight when he volunteered himself to help her, and a few days later ([[TimeTravel from her perspective]]) ''Tsuruya-kun'', regarding themselves as equals. Later on, in Chapter 45, he switches to ''Tsuruya-hime'' in order to better distinguish between her and Tsuruya-sama while around the Tsuruya-tachi.
** Mikuru starts calling Nagato ''Yuki-chan'' after [[spoiler:they comfort each other when Kyon is recovering from being shot.]]
** Tsuruya had called both Haruhi and Mikuru that they both should drop the formalities (''Tsuruya-san'') when talking to her. Haruhi has been calling her ''Tsu-chan'' since then, and Mikuru(big) calls her the same way.
** Kyon finally called Mikuru ''Mikuru-chan'' after watching a movie together and being ''asked again''.
** Tsuruya started calling Yuki ''Yuki-chan'' in Chapter 31.
** In Chapter 35, Kyon first calls Yuki ''Yuki'' when Haruhi asks her to make the club's filing cabinet secure. When visiting her later in the day, he calls her ''Yuki-rin'', before finally settling on ''Yuki-chan''.
** Kanae starts calling Mikuru ''Mikuru-onee'' in Chapter 38.
** Mikuru calls Haruhi ''Haruhi-chan'' in Chapter 41 after Haruhi tells her to stop calling her ''Suzumiya-san''.
** In an interesting take on this trope, Kyon's sister changes the way she calls her brother from [[EmbarrassingNickname "Kyon-kun"]] ''back'' to [[UsefulNotes/JapaneseSiblingTerminology "Nii-san"]][[note]]as she did in their backstory[[/note]] in Chapter 48. Contrary to what one might think, her reversal towards formality in fact denotes a improvement in their relationship after she has come to respect Kyon more and his (albeit reluctant) acceptance of Nonoko as an ally.
** Yuki calls Mikuru ''Mikuru-chan'' in Chapter 50.
** Sasaki gets ''Saki-nyan'' from Tsuruya in Chapter 56.
** Kyon calls Kuyou ''Kuyou-san'' [[spoiler:after he kisses her]] in Chapter 57.
* FiveRoundsRapid: [[SubvertedTrope Subverted]] after [[SwitchingPOV Sumiyoshi-rengo member Taiso]] signals to the other Yakuza members to pull out their guns when Koizumi uses his esper power to destroy Taiso's gun just as Taiso tries to fire it. Played straight when fellow Sumiyoshi-rengo, Senzo, fires five shots at Koizumi in his red energy form. Of course, this [[ImmuneToBullets fails to work]].
* FlashMob: In Chapter 53, the entire SOS Brigade plus Sasaki, Kyouko and Nonoko staged ''[[DancingTheme Hare]] [[EarWorm Hare]] [[ContinuityNod Yukai]]'' in a train station dressed as ''VideoGame/{{Touhou}}'' characters to the surprise and delight of many passers-by. Sasaki can't help but wonder if it might be part of a FlashMobCoverup.
* FlechetteStorm: Used twice by [[KnifeNut Asakura]] in Chapter 1.
* {{Flight}}: [[spoiler:Haruhi, as part of the [[PowerOverhaul upgrades she performs on her powers while in Safe Mode]].]]
* FoodAsBribe: [[spoiler:In Chapter 59, Kuyou unintentionally prevented Hanyuu from informing Rika about Kyon and the girls disappearing from Mion's house by bribing her with (you guessed) cookies.]]
* ForcedToWatch: Sasaki is made to watch on closed-circuit television Kyon and Yuki being ambushed by about thirty Sumiyoshi-rengo assassins. She thinks it's to torture her, [[JustifiedTrope but it's actually]] [[spoiler:to use [[PowerNullifier her power]] [[BroughtDownToNormal to disable Yuki's data manipulation and Kyon's superscience gadgetry]].]]
* {{Foreshadowing}}:
** In Chapter 3, Kanae commented that a few versions of Kyon from other universes knew about demons. Later chapters suggest that most likely she was talking about [[spoiler:Oyashiro-sama, the vengeful shrine god of Hinamizawa (also known as Hanyuu)]].
** Kyon mentions that his uncle is called Keiichi in Chapter 7. It turns out that's the same one in [[VisualNovel/HigurashiWhenTheyCry Higurashi]].
** Also this, from Chapter 9:
-->'''Yuuto:''' There's no way you could come home from school one day and announce that you had, say, rescued an heiress from rampant hoodlums and secured a position at her father's company.
*** And then, in Chapter 13, after the photography ring is shut down, Tsuruya's father visits Kyon's family and tells them that Kyon has secured a position at his company, due to Kyon rescuing his daughter from rampant hoodlums.
** In Chapter 31, Kyon quips that he doesn't have a "wise-cracking robotic sidekick" in response to Haruhi's remark about him becoming a [[ShoutOut lom]][[VideoGame/RatchetAndClank bax]] because of his tools. Ten chapters later he instead got [[spoiler:[[FunSize Achakura]], a [[ProjectedMan Projected Chibi]][=/=]FairyCompanion[[note]]an AugmentedReality construct to be precise[[/note]]]] whose nominal responsibility is to assist Kyon at handling the very complex AppliedPhlebotinum at his disposal.
** Yuuto is something of an OverprotectiveDad about her daughter. Chapter 59 reveals why.
** There is another one hidden in the RunningGag about Kyon fending off nonexistent accusations of being a {{lolicon}}. Unlike all the other people at the other end of the joke, his father's reaction consisted in a sharp wince and a quick change of subject. [[spoiler:This is most likely because he probably had to endure similar verbal barbs in the past after a very young (and even younger-looking) Akane gave birth to his first child.]]
* FountainOfYouth: After each [[YearInsideHourOutside training session]] Yuki restores the trainees' age, otherwise they'd age a year each night.
* FourIsDeath: [[DefiedTrope Defied]]. In Chapter 54, Koizumi is added to the group of people assigned to face the Combine (Kyon, Yuki, Kuyou, and Ryouko) the next time they appear "mostly to make the number involved slightly luckier."
* FramingTheGuiltyParty: Takahashi is arrested for kidnapping of a minor at the beginning of Chapter 49. While wrongly accused in this particular case, she did try to [[spoiler:kidnap Sasaki and Kyon with the help of the Sumiyoshi-rengo]] just the day before in-story.
* FreefallRomance: In Chapter 39, a hasty and ''very'' tricky exit from [[spoiler:Kuyou's Shadow Song]] teleported Kyon and Yuki to some point twelve kilometers above the sea at the south of Nishinomiya. After she navigated through the air to his side and grabbed his wrist to let him know she will handle the fall, Kyon nodded and hugged her tightly against himself. This gesture and the fact that Kyon asked for her help moments prior after a long while (for her) avoiding to "burden" her reassured Yuki and told her how much Kyon trusts in her and how needed she is for him, which is kind of a '''huge''' deal for her.
* FreudianSlip:
** Mostly from Kanae, followed by her [[LuminescentBlush blushing]].
--->'''Kanae:''' You got to take a bath with Sempai! I'm jealous! Er, I mean, that is... (claps hands over her mouth)
** Though Haruhi usually catches herself before letting something slip, she got one for the same scene as above, after prompting from Tsuruya.
--->'''Tsuruya:''' Understood! Next time I want to take a bath with Kyon, I'll invite you over to join us!\\
'''Haruhi:''' You'd better! ... (realizing) I mean, don't think like that!
** Mikuru has her own share when asked about the movie she went to watch with Kyon and Yuki.
--->'''Tsuruya:''' So, how was your date~?\\
'''Mikuru:''' W...wonderful. Ah! It, I mean, we had fun, er, the three of us! [[NotADate It wasn't a date]], Tsuruya!
* FriendlyTickleTorture:
** In a stroke of role-reversal humor, Kyon once woke up Nonoko with the aptly named "forbidden little-sister-submission-tickle-strike."
--->'''Nonoko:''' "T...tickle-ninja! No fair!"
** This trope was used as a joke threat in Chapter 61 by Mion and Satoko to get Rika to spill the beans about [[spoiler:Kyon's secrets]].
* FunnyAneurysmMoment: Chapter 59 has an unusual InUniverse example where the character's joke becomes ''very'' inappropriate only after another one asks what was intended as an unrelated question.
* FuroScene:
** A few times, first with Kyon and Tsuruya, then Kyon, Tsuruya and Yuki, and later Kyon and Haruhi.
** Then there's another in the Thwarted Lull arc.
** In the Fanservice Arc, when Kyon goes to Hinamizawa. Admittedly, Yuki and Hanyuu don't join him, but, well...
-->"We have just shared a wonderful experience," Hanyuu stated. "We should use this opportunity to become friends."
* {{Futureshadowing}}:
** Mori didn't go to the first meeting Kyon had with Organization members because she was intimidated by something Kyon did a few days before. In Chapter 26 Kyon is shown [[spoiler:bursting into a secret Organization meeting (falling through the skylight in a 10 meter drop) while carrying a man beneath an arm and calmly saying "Don't mind me dropping in," as if it is normal for someone to do this. He left through the skylight too.]]
** In Chapter 58 and shortly after they arrive to Hinamizawa, the SOS Brigade run into [[spoiler:Sasaki]]'s future self, who later will tell them about certain events that [[TimeTravelTenseTrouble took/will take]] place in Nishinomiya during the weekend, including: [[spoiler:another kidnapping attempt]], a CarChase and Kyon and [[spoiler:Haruhi]]'s involvement in these. Kyon takes the hint and decides to ask Yuki for some driving training in RetroactivePreparation for [[TimeTravel redoing the weekend]].
[[/folder]]

[[folder: G-I]]
[[#G]]
* GadgetWatches: Kyon's wristwatch [[spoiler:contains a skinsuit[[note]]a full-body armor that looks like black body painting when activated[[/note]] with the capability to selectively redistribute momentum over its surface[[note]]e.g. if Kyon gets shot, the skinsuit can spread the kinetic force of the projectile evenly over a much larger surface, depriving the bullet of its stopping power[[/note]], which in turn contains {{gravity ma|ster}}nipulators originally designed for [[JumpPhysics enhanced]] [[InASingleBound movement]]]]. It also doubles as a [[http://en.wikipedia.org/wiki/Radio_clock radio clock]] (useful for TimeTravel).
%%* GeniusLoci: [[spoiler:The Agents of the Sky Canopy Domain are the avatars of living, sapient stars. Part of the reason they don't get along with the IDSE is because the way the stars perceive time, matter, and thought are so vastly different.]]
* GenreSavvy: Many characters already are in the source material, but Haruhi turns this UpToEleven: [[spoiler:she uses her powers to give herself a limitation on them so she doesn't destroy the world accidentally; and while she learns to be responsible with her full powers she'll have a limited version of them so she can still have fun. Of course, things can go bad, as explained in BlessedWithSuck.]]
** Even Kyon's sister is starting to become this, though in her case it borders on WrongGenreSavvy: she was able to deduce that Kyon was visiting an enemy to draw him to their side, but at the same time [[DaydreamBeliever she ardently believes that she will become a Magical Girl on her next field trip]].
** Taniguchi seems to be well aware of his role as comic relief and makes the most of it. He even thinks that he got a girlfriend out of deal because it makes things funnier and he's ''definitely'' not complaining about that. As with Nonoko, he did get a [[WrongGenreSavvy few things wrong]] and thinks he's in a [[ShonenGenre shonen story]] with Kyon as the main character. For example, he incorrectly speculates that the NewTransferStudent in Chapter 62 is Kyon's "new fiancée" and/or someone he saved and who is joining the team. [[spoiler:He got ''very'' close though. Sasaki, who fills the bill to a T, was transferred to a different sophomore class.]]
* GilliganCut: As Haruhi initiates her [[spoiler: MemoryGambit]], she mentions in her narration that she's making a small change to Kyon as well. Cut to Kyon leaping out of his bed like a ninja in the morning with lots of energy, then deciding to go in to school early to study for a math test.
* GirlsAreReallyScaredOfHorrorMovies: After learning in Chapter 19 that Kyon promised Miyoko to take her to see a gory movie the [[YoungerThanTheyLook young girl]] so eagerly wanted to watch, [[GenreSavvy Haruhi]] invites herself and Mikuru along while expecting that this trope would come into play and hoping to {{invoke|dTrope}} a SecurityCling out of the time traveler. [[GoneHorriblyRight It goes better than planned]]: [[spoiler:Miyoko and ''[[HoistByHerOwnPetard Haruhi]]'' herself end grabbing his arms for comfort. Mikuru, on the other hand, ''leaps'' onto Kyon's lap and presses her face into his chest before the ten minutes' mark and remains that way for the rest of the screening]].
* GirlOnGirlIsHot: Kyon once had a dream of [[TimeTravel present!Mikuru]] [[ScrewYourself and]] [[TwinThreesomeFantasy future!Mikuru]] which he started reminiscing about. He cuts himself off before he [[DiggingYourselfDeeper digs himself deeper]].
** [[spoiler:He was also pretty interested when Haruhi kissed Tsuruya.]]
** [[spoiler:Nor did he have any objection when it was Tsuruya and Yuki or Haruhi and Kanae.]] Kyon is a very lucky boy.
* [[TheGlomp Glomp]]:
** Haruhi and Tsuruya to the already hugging Mikuru and Yuki [[spoiler:when Kyon is recovering from being shot at the hospital.]]
** Kyon is in the receiving end of one from his sister as a greeting in Chapter 35.
* GoodAngelBadAngel: [[spoiler:Achakura and [[FunSize chibi]]!Kuyou dressed the part and tried to play the role for Kyon in Chapter 54, with great emphasis on ''tried''. Let's just say that neither of them ''quite'' get BlackAndWhiteMorality]].
-->'''Kyon (to Angel!Ryoko)''': "I don't think you're supposed to tell me to be more violent when you're dressed like that."
* GoodCopBadCop: In the Heroic Antics Begin arc.
* GoofyPrintUnderwear: Kimidori Emiri wears Trope-tan character print panties.
* GoToYourRoom: Kyon's mother to her son in Chapter 13.
* GratuitousJapanese: Aside from using Japanese honorifics, the author uses a lot of Japanese words, especially with regards to the {{Yakuza}}.
* GrievousHarmWithABody: Kyon and Yuki use this trope a lot in both [[CurbStompBattle of their fights with the Yakuza]].
* GrowlingGut: Kyon in Chapter 45, after Mikuru asks him if he's hungry.
[[#H]]
* HalfTruth: Kyon tells Aida that his PDA is custom[[note]]Yuki made it from Asakura's data remnants[[/note]], and says that he got Akasaka's picture because if you do it right, people just look right through you[[note]]He made himself invisible[[/note]].
* HangoverSensitivity:
** Happens to almost all the members of the [[VisualNovel/HigurashiWhenTheyCry "after-school club"]] in Chapter 17. Mion seems to have it the worst, judging from her reaction to her sister's intentionally-too-loud greeting:
-->'''Mion:''' My head's killing me. Kei-chan, Rika-chan... if I don't make it... I'm leaving the household to Makoto-chan.\\
'''Shion:''' ''(yelling and banging the frying pan of eggs on the table)'' Good morning, nee-chan! How are you doing today?\\
'''Mion:''' ''(whimpering and clutching her head)'' Please, where are my henchmen when I need them?
** Subverted in Chapter 63. During a job-related event, Kyon had to drink some whiskey at the insistence of high-raking members of the [[{{Yakuza}} Yamaguchi-gumi]] to celebrate the good outcome of the meeting. To his surprise, he woke without a hangover the next morning and soon realized he had to [[MundaneUtility thank Yuki and her powers for that]].
* HeadPet: DeadpanSnarker Kyon + TeamPet [[spoiler:Achakura]] = Inevitability.
** As of Chapter 48, [[spoiler:chibi!Kuyou]] also takes a turn riding on Kyon's head.
* HeroesGoneFishing: Kyon goes fishing with his uncle Keiichi when he goes to visit for golden week.
** The entire Fanservice Arc counts as this.
* HeroesPreferSwords: In Chapter 61, Kyon uses a sword against what can be described as a WalkingTank. {{Justified|Trope}} by three reasons: it was a LaserBlade capable of cutting through its armor, he was under the protection of personal DeflectorShields and he made a point to ask [[spoiler:Achakura]] first to run electronic countermeasures to mess with his enemies targeting systems. [[spoiler:Still very risky.]]
* HeroicBSOD:
** Subverted, as the pressure of knowing the implications of her own power almost provokes one on Haruhi.
** Kyon suffers this on his backstory without realising it: after Sasaki [[TVTropesWillRuinYourLife constant deconstructionism]], culminating with the {{deconstruction}} of ThePowerOfLove, Kyon's sister notes her brother lost his smile, only to be regained after Kyon met Haruhi.
** Kyon comes to close to having one when the girls finally reveal the harem plot to him.
* HeroSecretService: The SOS Brigade, including the Organization and [[spoiler:Tsuruya's {{Yakuza}}]] for Kyon, for mostly non-action roles. Haruhi'd like to be in the action though.
-->'''Haruhi:''' *chuckling* Damn, I just realized, I'm stuck with Kyon's paperwork again!
* HesitationEqualsDishonesty: Kyon does this in Chapter 6 when Tsuruya asked why he had to return to the clubroom despite him telling her earlier that he was dismissed for the day. It turns out he had to find Mikuru to TimeTravel.
-->'''Kyon:''' Well, I have to head back in anyway, since ... I forgot my shoes. Yeah. I'll see you tomorrow, alright, Tsuruya-sempai?
* HiddenDepths: Pretty much every named character and a few more. A particularly poignant example is Kyon himself, who in Chapter 5 revealed to Haruhi that the reason why he always kept certain emotional distance until then, at least enough to prevent a RelationshipUpgrade with her, has nothing to do with the supernatural. [[spoiler:He was convinced that if they ever hooked up, Haruhi would eventually get ''bored'' with [[HeroicSelfDeprecation someone as unremarkable as him]]. Being the snarky friend who complains from the sidelines? Sure, he can handle that. Getting rejected for such a reason? No way.]] This argument can be easily extended to Yuki and Mikuru. Probably the only reason why he allowed himself to fantasize with the latter is that he "knew" via RetroactivePrecognition that nothing would come out of it even if he did.
* HighAltitudeInterrogation: How [[spoiler:Kyon]] made [[spoiler:Yamane]] spill the beans in Chapter 11.
* HolographicDisguise: The [[ChangingClothesIsAFreeAction "stealth function"]] of Kyon's greatcoat. Outfits need to be scanned first, but the OS is smart enough to build a sufficiently interactive 3D model from ordinary pictures.
* HolyBacklight: Kyon is seen that way by Kanae in after fighting a giant robot at the beach.
* HopelessSuitor:
** A minor [=PoV=] character from Chapter 51 called Oe Akito is this for Haruhi. She caught his attention since her performance as [[GirlGroup ENOZ]]'s replacement vocalist during the last [[SchoolFestival Cultural Festival]] and later he became enamoured by her strong, indomitable personality. By the time he was ready to make his move though, the president of the Martial Arts Club also discovered that Haruhi was evidently interested in certain "snarky standoffish guy", which made him give up on trying to approach her. After the news about Kyon's engagement went public, Akito got his hopes up again and he was even willing to challenge Haruhi's supposed rebound guy to a fight until he learned that the "guy" was a small first-year ''girl'', realizing that there was ''no way'' to drive Kanae off without coming across as an inexcusable jerk.
** Yuki rejected at least two members of the Computer Research Society who confessed to her after the accidental announcement of Kyon and Tsuruya's engagement. It's implied that their president feels the same way but he gave up long ago because he somewhat realized just how important Kyon is for Yuki.
** Mikuru, Kitago's SchoolIdol, has them literally by the dozen. After Kyon supposedly got out the way, things got so bad that she had to [[InventedIndividual invent a boyfriend]] who attends to a distant high school so they would leave her alone. She gets bonus points because she [[MetaphoricallyTrue convincingly described her boyfriend by simply speaking about Kyon with a different name]].
** Kunikida carried a torch for Sasaki since middle school. [[spoiler:She definitely turns him down in Chapter 48.]]
** [[LoveEpiphany Once she realized her own feelings]], Sasaki considered herself one for the already engaged Kyon. [[spoiler:Subverted later on in Chapter 60.]]
* HowMuchDidYouHear:
** In Chapter 18, Kyon discovers his sister eavesdropping Haruhi when [[spoiler:she's outlining her plan [[MarryThemAll to share Kyon]] to Mikuru]]. While Tsuruya wonders what she overheard, Haruhi doesn't really care about how much exactly she knows: she just cares that she doesn't tell anybody else.
** It happens again in Chapter 32[[spoiler:, just after Haruhi [[TheGlomp glomps]] Kanae and Mikuru:]]
--->[[spoiler:'''Haruhi:''' "Making such cute noises... if he ever tries to start something, those sounds will make Kyon unable to stop!"]]\\
[[spoiler:'''Mikuru:''' "S...Suzumiya-san! Spare Kanae-chan! T...take me instead!"]]\\
[[spoiler:(Haruhi is interrupted by a far-too familiar tug on the collar of her shirt)]]\\
[[spoiler:'''Haruhi:''' "Eh? Y...you, H...how long...?"]]\\
[[spoiler:'''Yuki:''' " 'If he ever tries to start something, those sounds will make Kyon unable to stop' "]]\\
[[spoiler:'''Kyon:''' "Somehow, I wasn't really sure that I should interfere..."]]
* HugeGuyTinyGirl: Tsuruya observes that [[spoiler:Kasai and Mori]] appear to be this after they start dating.
* HumansThroughAlienEyes: In the sections shown from Kuyou's point of view. For example, she's seen observing baking cookies with childish fascination and she seems to equate interpersonal relationships to complex orbital systems to facilitate her comprehension.
* HumiliationConga: [[spoiler:Yamane Jun.]] After him being caught off-guard by Tsuruya in the idol research club room [[spoiler:and tried to kill her]] Kyon held him by an ankle, his body dangling outside a third floor window, making people who was passing by take photos with their phones. Then he just had to wet himself.
-->'''[[TheHyena Tsuruya]]:''' That's precious! I'll make sure one of those pictures of you that's being taken down there now is right next to the article about this that'll be in the paper!
* HyperspaceArsenal: Somehow, Kyon tucked his slider weapon into his shirt from Haruhi's point of view.
* HypocriticalHumor:
** [[CannotKeepASecret Nonoko]] in Chapter 17:
--->"Yeah," Kyon's sister agreed, pouting. "You're not very good at keeping secrets."
** Haruhi's rant in Chapter 27 about long and/or ongoing series. She's especially unhappy that [[MahouSenseiNegima Negima]] is that long, but the part that sticks out most is that she doesn't like light novels that go on for more than 10 novels. The source material is releasing its 10th novel, and it's only the start of the Brigade's second year.
*** In addition, this fanfic is ''quite'' long (see {{Doorstopper}} above), and was the longest Haruhi fanfic on fanfiction.net before the author removed it and reposted it[[note]]Although the fanfiction.net version only holds up to Chapter 29[[/note]].
** Mikuru's "it's forbidden" speech in Chapter 29.
[[#I]]
* IaijutsuPractitioner: An {{Elite Mook|s}} from the [[{{Yakuza}} Sumiyoshi-rengo]] used an iaijutsu technique against Kyon in Chapter 44. [[spoiler:Kyon barely managed to parry the attack, breaking his own sword in the process, and then he took advantage of his opponent's surprise to sucker-punch him in the side of the face.]]
* ICallItVera: Kyon's {{Morph Weapon}}s, [[StellarName Altair a]][[{{Tanabata}} nd Vega]], and his [[LaserBlade Beam Saber]], [[VideoGame/{{Touhou}} Hakurouken]].
* ICannotSelfTerminate: [[spoiler:Achakura]] says this word-for-word in Chapter 48. She's horribly upset at two things: her actions directly lead to Kyon's sister being in severe danger, and she's [[spoiler:feeling 'Negative' emotions like sadness, worry, and guilt for the first time]], and hates it. In order to let herself stop feeling that way, she gives Kyon [[spoiler:the schematics to a special form of his LaserBlade that can erase her from existence. He's tempted to do so because of the danger to his sister, but is talked out of it when he's told that she was honestly trying to save his life, and never intended to bring Kyon's sister to the front lines.]]
* IdenticalTwinIDTag: Invoked by Haruhi in Chapter 47 when an identical AlternateSelf of [[spoiler:Suou Kuyou]] appears. She quickly decides to tie one of [[IconicItem her golden ribbons]] to her friend's hair to avoid mixing them up.
* IfIHadANickel:
-->'''Haruhi:''' "If I had a paper crane for all of the things that Kyon's done for me, [[ThousandOrigamiCranes I'd have a wish by now]]!"
* IKissYourHand: In Chapter 33, Kyon, [[InstantCosplaySurprise wearing a Victorian-style suit]], plays along with Yuki's, wearing an ElegantGothicLolita outfit, offer of tea making this gesture (ItMakesSenseInContext). While he makes the gesture his lips don't actually touch Yuki's hand.
* ImagineSpot:
** In Chapter 13, after Kyon phoned Yuki.
--->He stared a minute longer, imagining her in her apartment, kneeling by the phone, her cheeks pink-tinged as she daydreamed about him... But he dismissed that thought. This was Yuki, after all. As much as he might wish that...
** Kanae dreamed of kissing a shirtless Kyon in a shadowy wooded glade surrounded by bunnies and flowers, not [[spoiler:on a beach, after fighting off an inter-dimensional robot.]]
* ImperialStormtrooperMarksmanshipAcademy: What would [[GenreSavvy Kyon]] do before going all CQC against a WalkingTank? {{Invoke|dTrope}} this trope by deploying ECM to make himself difficult to target on.
* ImTakingHerHomeWithMe: Performed by the TropeNamer, Ryuguu Rena, on a cosplaying Yuki in Chapter 42. [[EmpoweredBadassNormal Kyon]] ''barely'' held her back from {{glomp}}ing Yuki, but [[DoubleSubversion she swept her up anyway the moment Kyon let go]].
** Haruhi does this to Kanae in Chapter 31, although not quite as extreme.
--> "God, she's cute like that, though," Haruhi exclaimed, grabbing Kanae away from her sempai suddenly. Kanae allowed another squeak of alarm to escape as the older girl held her tightly and twirled around. "I want to take her ''home!''"
* IncomingHam: In chapter 57, when Taniguchi greets Kunikida with a YouExclamation, [[GivingSomeoneThePointerFinger pointing his finger towards him]]. Actually an inversion because it was Kunikida who was entering the scene (Taniguchi was waiting for him to arrive this whole time) but it had the same effect as a straight use.
* InconvenientSummons: [[spoiler:When they start training]] Yuki teleported Mikuru two nights in a row to her apartment just after Mikuru took a bath, still wearing her ModestyTowel. After complaining about being teleported while bathing [[LiteralMinded the next teleport was while she was eating]].
* IndirectKiss: Kyon and Yuki. Kyon's aunt observes no real hesitation on his part when he has to share a teacup with Yuki.
* INeedToGoIronMyDog: In Chapter 31, [[spoiler:after Yuki teleports Kyon with the intention of letting Haruhi having a make out session with him]].
-->'''Kanae:''' We have to take care of that ... thing in the kitchen, right Asahina-san?
* InMediasRes: The prologue.
** We finally reached the events it covers [[BrickJoke after 41 intervening chapters]].
* InnerCitySchool: "Hikami Gakuen" was mentioned only in passing during Chapter 12 and promptly described as "the delinquent capital of our city."
* InnocentFanserviceGirl:
** Tsuruya happily undresses in front of Kyon, after they slept together ([[InnocentInnuendo No, not that way]]). She also bathes with him, and almost gives him a nosebleed the first time.
** Yuki offers to teach Haruhi how to kiss better. Haruhi's mind goes into overdrive.
** If Mikuru's thoughts are to be trusted, Tsuruya never bothers with a ModestyTowel. Ever.
** Thanks to her tendency to imitate others [[spoiler:and Achakura's encouragement]], Kuyou picked up the habit of using her powers to dress herself up without really minding ''what'' she is wearing. So far, her outfits range from the [[RuleOfCute adorable]] to the [[RuleOfSexy "distracting"]] with a tendency to the former.
* InnocentInnuendo:
** Crops up on occasion. First between [[spoiler:Kanae and Kyon]], then later with [[spoiler:Kyon, Yuki, and Tsuruya]].
** In the prologue, Haruhi asks Kyon eagerly to "see it", asking in the process "Doesn't that get hot?" with a wide smile. [[spoiler:It's his [[LaserBlade beam saber.]]]]
** [[spoiler:Kanae slept with Kyon, and Haruhi immediately lampshades everything when she meets them]].
---> [[spoiler:'''Haruhi:''' Wow. Just ... around you, Kyon, that slider turns into a living innuendo ''factory''. Kanae-chan's little 'you wore me out last night' comment, her constant {{Freudian slip}}s, and now, 'accidentally falling into your bed'? I can't even bring myself to get worked up over the things that get said between the two of you - what ''really'' happened? And where'd the Trope-tan cosplay come from?]]
** In Chapter 63, Haruhi provides a hilarious example.
--->'''Haruhi:''' (...) there's this nice little thing where we take turns sleeping with Kyon.
* InnocentlyInsensitive: Kanae in Chapter 63. [[spoiler:Haruhi was feeling somewhat down because she wasn't able to be of much help to the team lately and increasingly frustrated because several high-priority situations in a row got in the way of her time with Kyon. When she finally got a chance to arrange a date, Kanae mistook Haruhi's words and enthusiastically accepted the invitation intended for Kyon. Thankfully Mikuru presented her own plans for a date with "Shutaro" and they decided to make it instead a double ([[MarryThemAll single?]] [[{{Polyamory}} quadruple?]]) date for the four of them.]]
* InsistentTerminology: Yakuza members tend to refer to their own organization as "ninkyo dantai" (任侠団体 or 仁侠団体, "chivalrous organization") and enemy organizations as "bōryokudan" (暴力団, "violence group"). The police also tend to use "bōryokudan".
* InstantArmor: Yuki adds this function to Kyon's watch, which saves his life [[spoiler:when he gets shot]].
* InstantCosplaySurprise: Haruhi modified[=/=]learnt that Skynet, Kyon's PDA and controller of [[ChangingClothesIsAFreeAction the stealth function on Kyon's greatcoat]], can scan pictures from the Internet. The first thing she does is make Kyon wear a Victorian suit, followed by various outfits from the same era.
* InternalReveal: In Chapter 16, Rika Fuurude tells Kyon about the events of VisualNovel/HigurashiWhenTheyCry, hoping he'll reveal his story after that. Understanding that [[SecretKeeper she'll believe him and will keep his secret]], Kyon tells Rika afterwards about the SOS Brigade and the supernatural events he had lived through.
* InventedIndividual: "Shutaro", originally just Mikuru's non-existent [[TheBeard Pretend Boyfriend]] (see HopelessSuitor above), becomes Kyon's {{holographic|Disguise}} SecretIdentity. This cover identity is based on an aged-up version of one of his younger cousins (specifically the one who thinks that GirlsHaveCooties) and occasionally goes in dates with Mikuru.
* InverseLawOfUtilityAndLethality: Kyon's [[AppliedPhlebotinum equipment]]. All in all, Kyon's more lethal tools (i.e. his LaserBlade, [[MorphWeapon slider guns]] or [[spoiler:the suborbital KillSat]]) remain largely unused in comparison to the support ones (e.g. InvisibilityCloak, [[ChangingClothesIsAFreeAction stealth function]] and particularly the [[InstantArmor skin]][[GravityMaster suit]]).
* InvisibilityCloak: [[spoiler:Kyon's equipment]] provides him with one of these at will. Well, so long as he's not too cold.
* IShouldWriteABookAboutThis: Rena used some of [[VisualNovel/HigurashiWhenTheyCry her and her friends experiences]] for some of the plots of her ''[[ShowWithinAShow Brave Detective Sasha]]'' series in a [[ParentalBonus cleverly covert and toned-down way]]. [[WhatDoYouMeanItsForKids The books are intended for children and teenagers after all]].
* [[IThinkYouBrokeHim I Think You Broke Her]]: After [[spoiler:Yuki makes modifications to Kuyou using Haruhi's (Kyon-approved) RealityWarper powers]], Haruhi and Tsuruya start to ask Kuyou some questions. When Tsuruya asks her [[spoiler:why she wanted to be linked to Kyon in the same manner as Ryouko]], she considers the question... and freezes, causing Haruhi to wonder if Tsuruya broke her.
-->'''Haruhi:''' Tsu-chan, did you just break Suou-san?\\
'''[[spoiler:Ryouko]]:''' I don't get it! It's like she suddenly got overwhelmed as soon as she tried to access a memory!
* ItsALongStory: In Chapter 4, after Kyon returns to the clubroom with a little cut in the head, a faint line of blood trickling down one cheek:
-->'''Haruhi:''' What happened?\\
'''Tsuruya:''' You're still bleeding? But I put a bandage on that for you yesterday!\\
'''Kyon:''' Long story.
* [[ItWasADarkAndStormyNight It Was A Dark And Stormy Morning]]: Averted, though Kyon really wants that when he wonders whether Haruhi will end the world after the previous night's incident in Chapter 28.
* ItWasAGift: When Kyon goes with Yuki to buy a phone to her in Chapter 27 Yuki acknowledges that, even if she could emulate the functions of a phone without effort, she would treasure it as a gift from him.
** Also, Mikuru's mail and photo to Kyon in Chapter 15. Kyon finally admits to Mikuru keeping her photos without her consent and deletes them in front of her, thinking he's being hypocrite after breaking the illegal photo ring. After a really uncomfortable day for both of them, Kyon receives a [[ShipTease mail from Mikuru with a photo of herself with a very shy look and skimpy clothing]], implying she forgives him. In a later chapter Kyon comments to adult!Mikuru that photo is meaningful to him.
* ItWillNeverCatchOn: Haruhi thinks Kyon's nickname for his beam saber in its tool mode will never catch on. He calls it his [[Series/DoctorWho sonic screwdriver]].
* IWasJustJoking: In Kyon and Haruhi's first meeting with [[spoiler:[[OCStandIn Michikyuu Kanae]]]], Kyon jokingly suggests that she's a slider who knows them from a {{Alternate Universe}}s after she ran away from them. Haruhi starts chasing her before he could say the line. He was right.
[[/folder]]

[[folder: J-L]]
[[#J]]
* JawDrop:
** This is the reaction of Kyon's father on how Tsuruya's father countered his negative to change jobs due to loyalty to his company (so Kyon's father could work under Tsuruya's father): buying the company where Kyon's father works.
** Koizumi in Chapter 29 when he's told [[spoiler:Kyon got [[ArrangedMarriage engaged]] to Tsuruya]].
* JumpPhysics:
** Yuki jumps from the ground floor, hops off the wall several times, and hangs on the roof one-handed before she slides [[spoiler:Yamane Jun's]] window open. Kyon looks at that and decides that his chance of mimicking her is nonexistent.
** Later, Kyon invokes this trope via gravity manipulation and his training.
* JustBetweenYouAndMe: Haruhi tried to [[InvokedTrope invoke]] this trope to get information out of a {{yakuza}} in Chapter 55, who not only [[SubvertedTrope subverts]] it but also [[DiscussedTrope points out]] that "smart people know better than to entrust critical and -- more importantly -- incriminating information to pawns like [himself]". Not a great loss because Haruhi [[spoiler:and Sasaki]] mainly wanted [[KansasCityShuffle to keep his attention away from]] [[spoiler:Haruhi's cell phone while she called for help]].
* JustInTime: In Chapter 44, Kyon and Yuki are forced to fight over thirty Sumiyoshi-rengo while most of Kyon's equipment is disabled and Yuki is BroughtDownToNormal. The ''second'' katana Kyon took from his assailants eventually shatters, which is when the Yakuza decide to stop holding back and draw their guns. It is at this moment that Koizumi bursts through the ceiling while destroying the ceiling cameras that were set up to allow a PowerNullifier to be in effect.
[[#K]]
* {{Kawaiiko}}: {{Discussed|Trope}} in Chapter 10.
-->'''Haruhi:''' "What about a stewardess? Yeah, with your kawaiiko features and small frame, I think you would look even more moe in uniforms."\\
'''Kanae:''' "Ooh, that might be fun! But I'm not a kawaiiko, I use 'I' (...) [[ThirdPersonPerson Would Sempai like Kanae-chan more if she refered to herself in the third person?]]"\\
'''Haruhi:''' (crosses arms making a 'X' sign) "Negative! Too burikko ... and if you become a natural, it'll be a kawaiiko overload."
* KillSat: Gungnir isn't quite orbital, but the effect is the same.
* KineticWeaponsAreJustBetter: In Chapter 61, Kyon [[OneHitKill One-Hit Kills]] a [[spoiler:Strider]] with [[MorphWeapon Altair]] in [[MagneticWeapons railgun-like]] configuration.
* KnowWhenToFoldThem: Daimonji was the only member of the [[spoiler:photography ring]] who gave up rather than resisting. He got off the lightest.
[[#L]]
* ALadyOnEachArm: A bit of a {{decon|struction}}[=/=]{{recon|struction}}. This trope becomes a common expression of affection among Kyon and his girlfriends, however it's something they rarely can get away with in public (e.g. sitting in the same row in a movie theater and when the light are dimmed).
* LampshadeHanging: If every time something was lampshaded was listed, we'd probably make the page four times longer.
* {{Laserblade}}: Kyon wields one in the prologue and finally gets it in Chapter 31.
* LaserGuidedAmnesia: After [[YearInsideHourOutside each session of training]], Yuki clears out "all non-necessary mental data to prevent unintentional corruption or trauma" from the trainees.
* LastSecondWordSwap: Haruhi in Chapter 62:
-->"Nothing but the best for Kyon's girl... cohorts"
* LatexSpaceSuit: Played with. Kyon's "[[BulletProofVest skinsuit]]" looks like black BodyPaint when activated, thus having the "form fitting" requirements down pat, but it's an InstantArmor designed to be turned on and off without any need of removing whatever other clothes he could be wearing at the moment and his [[BadassLongcoat coat]] prevent ClothingDamage as par for the course, so it's unlikely that it'll play any {{fanservice}} role whatsoever.
* LeapOfFaith: There is an interesting instance in Chapter 47, where Kyon tried to use his [[GravityMaster gravity manipulators]] to jump from ground floor to the rooftop of a building [[spoiler:in an attempt to get himself and Kuyou away from a group of enemy Synths trying to gun them down]]. In this case it's not that Kyon couldn't see where he would land, but rather he had the certainty that the jump was ''beyond'' the limits of his [[JumpPhysics physics-defying equipment]] unless [[spoiler:an almost unresponsive Kuyou would be able to deduce his tacit intentions and spare a little bit of her power to give them the necessary momentum to cover the required distance while still devoting most of her efforts to repel the actions of her alternate self]]. In other words, he bet on something that only happened once before.
* LeaveTheTwoLovebirdsAlone: Yuki in Chapter 29, when she left [[spoiler:Mikuru and Kyon]] alone by the entrance of Tsuruya's house.
* LesserOfTwoEvils: Even if Kyon hardly qualifies as "evil", that's not a clear-cut conclusion for the SympatheticInspectorAntagonist Akasaka Miyuki. From her perspective, he's a remarkably competent {{yakuza}} who leaves little to no incriminating evidence behind and a well-regarded member of the biggest crime syndicate in Japan. However, in Chapter 61 Miyuki discovers [[spoiler:that Kyon's actions could be preventing supernatural dangers from reaching innocent people and she resolves to try to keep the law's eyes off Kyon.]]
* LiteralMinded: Kyon's PDA. In Chapter 29, when Kyon starts chatting with Sasaki she brings up that most of his events were most probably organized by someone else. His PDA, being able to learn and adapt, brings up his event planner immediately. He then tries to avoid meetings with her with lame excuses that Skynet (his PDA) obligingly fills his schedule with as it doesn't understand Kyon is lying.
** An alternate interpretation is that Skynet knew Kyon was lying, but was helping him out anyway - as Kyon never makes any mentions of Skynet reminding him of any of his false excuses. Either he deleted them later or Skynet did it for him.
*** A third alternative is that Skynet knew he was lying, but was doing it to mess with him. Given how it reacted to losing at chess, and changed its name back after Haruhi switched it...
** Kuyou. When asked if she knows what udon is, she responds by listing its chemical composition. And after hearing Kyon say he is going to "A Special Hell", she decides she has to find the special hell so she can go with him.
* LivingEmotionalCrutch: {{Defied|Trope}}. Once the Brigade realized how emotionally dependent [[spoiler:Kanae]] was on Kyon, they made a conscious effort to make her understand she can rely on ''all'' her friends.
* LockedOutOfTheFight: While the whole SOS Brigade was in class when the enemy slider attacked Kitago the battle was inside Kuyou's [[PhantomZone shadow song]]. Koizumi can't enter those spaces by himself.
* LockedOutOfTheLoop: The males in the SOS Brigade don't know that [[spoiler:the females in the brigade are aiming [[MarryThemAll to share Kyon]].]]
** As of Chapter 40, Kyon has been brought into the loop. Koizumi still doesn't know, though.
** And as of Chapter 52, Koizumi has figured it out.
* {{Lolicon}}: Kyon isn't pleased to note that Taniguchi thinks Kanae's cute, in a lolicon sort of way.
** And a running gag has Kyon denying that he feels this way for younger girls like Miyoko and his cousin.
* LoopholeAbuse:
** In Chapter 47, the only way [[spoiler:Asakura Ryouko]] could circumvent "good-child mode" and alert the brigade of [[AlienInvasion a slider attack]] was get [[spoiler:Kyon's sister]] to speak to her first and convince her to activate Kyon's tools and deliver them to him.
** Tsuruya commented in Chapter 63 that she promised ([[BrickJoke way back in Chapter 14]]) she wouldn't bathe with Kyon again until she gets the chance to invite Haruhi over to join them (ItMakesSenseInContext). Yuki, always a helper, pointed out that the specific wording of the promise didn't forbid them from ''showering'' together. [[spoiler:They still didn't go for it, though.]]
* LoveDodecahedron: Kyon-centered. Putting aside the already established (semi-){{canon}} pairings of [[OfficialCouple Haruhi]], Mikuru and Yuki, Kanae's crush on him was obvious enough since her first appearance in the story[[spoiler:[[note]](to be precise, [[DimensionalTraveler Kanae]] became interested in Kyon after meeting numerous [[AlternateSelf alternate versions]] of him)[[/note]]]], [[spoiler:Tsuruya]] Haruka eventually admits to harboring similar romantic feelings for him, and [[spoiler:as of Chapter 30, the normally unflappable Sasaki is undeniably distressed by news of his engagement to Tsuruya, although [[ObliviousToLove she's unable to identify why she's distressed by that in the first place]]. Furthermore, Kuyou's love has been confirmed. Aside from those centering Kyon, Sakanaka is implied to like Kunikida, who in turn harbors an unrequited crush towards Sasaki.]] Gosh, this is a worthy rival to Manga/SchoolRumble.
* LuminescentBlush:
** Kanae. Almost always when the situation involves Kyon.
** Also Mikuru in the picture she sent to Kyon in Chapter 15.
** And Haruhi, after kissing Kyon in Chapter 29. Also Koizumi because he's linked to Haruhi.

[[folder: M-O]]
[[#M]]
* MagicSkirt: Averted by Kuyou in Chapter 37 during a DynamicEntry. Both the trope and the aversion are surprisingly underplayed, all considered.
* TheMaidenNameDebate: [[VisualNovel/HigurashiWhenTheyCry Maebara Keiichi]] changed his family name to ''Fuurude'' when he married Rika as per custom in Hinamizawa to preserve the traditional name of the {{shrine maiden}}s that minister to Oyashiro-sama's shrine.
* MajorInjuryUnderreaction:
** In Chapter 22, [[{{Yakuza}} Iyouji]] is shocked to realize that Kyon dismissed [[spoiler:being shot]] so easily.
** The above example could be chalked up to the fact Kyon lost consciousness too quickly and [[spoiler:that the emergency medical function of his skinsuit]] pretty much guaranteed his safety from such a wound. But then in Chapter 60, when discussing something about one of the guys responsible of the attack, Haruhi and Tsuruya remarked that [[spoiler:the shooting]] doesn't even ''cross'' Kyon's mind when he was voicing his grievances against [[spoiler:Ryuugu Ryo]].
* ManlyTears: Kyon, after [[spoiler:his aunt Rika told him [[VisualNovel/HigurashiWhenTheyCry her backstory.]]]]
* MarryThemAll: [[spoiler:Keiichi has ended up in this situation despite being married to Rika, and Haruhi is aiming for this.]]
** This is actually deconstructed and then reconstructed in the same chapter. [[spoiler:According to Rika, the romantic situation at the end of [[VisualNovel/HigurashiWhenTheyCry the Higurashi series]] turned into a NoRomanticResolution situation for several years until Rika was physically old enough to make her move on Keiichi, but [[ClingyJealousGirl the way she tried to catch Keiichi's notice]] nearly destroyed her and Keiichi's relationship with [[FirstGirlWins Mion]] and the rest of their friends (and considering that this is Higurashi, [[MurderTheHypotenuse it's not hard to imagine]] how ''that'' might've played out). Disaster was only averted at the last moment when a MarryThemAll solution was proposed by Rena and Satoko and accepted by the rest of the group.]] Even then, it's not an easy relationship to have; it only works because the whole group were iron-clad TrueCompanions before they were a harem, and each of the girls has enough self-esteem and love for their partners to not worry about him ever abandoning them.
* MarshmallowHell:
** [[spoiler:Haruhi pulls Mikuru onto Kyon]] while wrestling for control of a letter in his jacket. The result is this trope.
--->'''[[spoiler:Kyon]]:''' I might have died happy.
** Also, Mikuru pulls one on Yuki, leading to a rather deadpan comment from Yuki. ItMakesSenseInContext.
--->'''Yuki:''' It becomes difficult to breathe. Is this ... appropriate?
* MathematiciansAnswer:
** In Chapter 26, Yuki hugs Kyon to buy Haruhi time to play with his PDA at the latter's request, cueing this exchange:
---> '''Haruhi:''' Er, er, good work. Um, more emotion next time, Yuki, and then we'll have that sequel down solidly!\\
'''Yuki:''' Good.\\
'''Haruhi:''' That means you can let go!\\
'''Yuki:''' Understood.\\
'''Haruhi:''' That means ''let go''!
** Yuki and Kanae use this trope while at Tsuruya's house in Chapter 36, when Yuki and Haruhi are forcibly undressing Kyon, while Kanae is getting out the various layers of his kimono out of a bundle.
--->'''Kyon:''' Y...Yuki! Kanae-chan! Come on! H...help me- Waaah! Help me out!\\
'''Yuki:''' I am helping.\\
'''Kanae:''' I'm trying!
** Yuki gets another, amazingly cute one in Chapter 40. [[spoiler:Kyon wakes up to find both Yuki and Kanae in his bed.]]
--->'''Kyon:''' Um...Good morning?\\
'''Yuki:''' Yes.
* MeaningfulEcho: In Chapter 6.
-->(In a reunion with the Student council)\\
'''Kyon''': I don't really believe that last part, but it's nice of you to say. I just want to point out, though, that a challenge against any one of us is a challenge against all of us(...).\\
(Immediately after Kyon stops talking Haruhi barges in the room)\\
'''Haruhi''': Trying to pick us apart by calling out my underlings when I'm not around, eh? Well, you've got a lot to learn! A challenge against one of us is a challenge against all of us!
** Also, Mikuru's response to Kyon getting a minor injury with "Kyon, don't die!" Then, after [[spoiler:Kyon is shot]], Mikuru responds with the same line, just before fainting.
* MegaNeko: [[spoiler:Shamisen, on Nonoko's [[BigDamnHeroes arrival]] during the Resonance Cascade.]]
* MissionControl: Haruhi and Tsuruya for Kyon when he and Sasaki go to meet the Anti-SOS Brigade.
* MobWar: Kyon's actions together with the involvement of the NPA caused the Sumiyoshi-rengo to declare war against the local groups associated to the Yamaguchi-gumi due to the loss of billions of yen in potential profits. There is a little of {{deconstruction}} going on as none of organizations really want an open conflict but the Sumiyoshi-rengo can't afford to do nothing and lose face, which would just deepen their problems.
* MoodWhiplash: Invoked in Chapter 59. After the reveal of the difficult circumstances surrounding [[spoiler:the past of Kyon's parents]], Tsuruya tried to lighten the mood by remarking how Mion was perhaps the basis of Kyon's "type" (key words: "[[BuxomIsBetter bonbons]] and ponytails"). [[spoiler:It worked.]]
* MomentKiller: The enemy slider in Chapter 30. [[spoiler:He found Kanae just when she was going to kiss Kyon]].
* MorphWeapon: One of the slider's enemies has one. [[spoiler:Kyon receives it later as a present from his future self.]] Also, in Chapter 30, one of the enemy sliders attack, only for Fujiwara and Kuyou to perform a VillainousRescue. [[spoiler:Kuyou reprograms one of the weapons for Kyon, only for Fujiwara to take it. She reprograms another one for Kyon anyway.]]
* MuggleBestFriend: Sakanaka and Yanagimoto to Haruhi.
* MundaneUtility:
** Yuki used data manipulation to slow relative time around a kettle to preserve tea and prevent it to cool down in Chapter 32.
** Haruhi often makes random items such as knives, forks, and pencils move on their own simply because she doesn't feel like cooking/writing physically.
** Kyon turned one of his [[MorphWeapon slider guns]] into a cosplay prop in Chapter 42, and he frequently uses his disguise coat for the same purpose.
** It's hinted that Yuki opted for data manipulation to give herself real long hair instead of using a wig during the FlashMob in Chapter 53, and Haruhi used her power to make her hair grow faster, although not quite unbelievably fast.
** Kuyou's "[[NotHyperbole Grand Alchemy of Cookie Creation]]" in Chapter 57.
** As part of her training on [[TeleportersAndTransporters teleportation]], Kanae learned to ''very'' accurately assess and recall sizes and forms at a glance. Said skill is incidentally very helpful when cooking, allowing her prepare and portion the ingredients to match precisely the requirement of the intended dishes.
** Yuki spared Kyon from a {{hangover|Sensitivity}} by neutralizing the alcohol's effects with her powers.
* MustHaveCaffeine: Coffee seems to be Keiichi's remedy of choice [[HangoverSensitivity whenever he drinks too much]]. Satoshi, on the other hand, seems to need his morning fix, as well, even without drinking.
-->Rika smirked, helping Shion with the kitchen chores until the coffee machine chirped. Keiichi and Satoshi stumbled into the room as if summoned by the chime, both wearing robes and with roughly identically bedraggled hair in their respective shades. "Coffee," they moaned in synch, zombie-like.
* MyOwnGrampa: Kyon hopes that this isn't the case, after realizing that he time travels a lot, and that he wouldn't have to go back in time [[StableTimeLoop and ...]]
* MythologyGag:
** [[spoiler:Asakura gets turned into [[Manga/HaruhiChan Achakura]].]] The chapter marks the [[FirstNameBasis first time Haruhi is called]] "[[Manga/HaruhiChan Haruhi-chan]]".
** Also, the later chapters reference information that was given in the later books such as Itsuki supposedly being the leader of the Organization and Sasaki and Haruhi having gone to elementary school together.
** In Chapter 51, Haruhi gives Kanae a smiley-face hairpin, which is the same HairDecoration as that worn by Yasumi, the {{Canon}} character Kanae was based upon.
[[#N]]
* NarrativeProfanityFilter: [[spoiler:Hanyuu]]'s outburst in Chapter 59, described via Yuki's narration:
-->[[spoiler:Hanyuu]]'s reaction was to emit an ''entirely'' unexpected string of words -- the kind of language that Yuki had read was typically related to European mariners.
* NeighbourhoodFriendlyGangsters: The [[spoiler:Tsuruya]] {{Yakuza}}, especially since their current oyabun and his YakuzaPrincess daughter[[note]]Tsuruya Haruka (Tsuruya-san), if you don't already know.[[/note]] take the "Neighbourhood Friendly" part literally.
** The Yamaguchi-gumi (the [[spoiler:Tsuruya family]] {{Yakuza}} is a branch of it) were responsible for most of the relief and aid efforts after the [[http://en.wikipedia.org/wiki/Great_Hanshin_earthquake Kobe earthquake]], as Kyon commented in Chapter 8. [[http://www.nytimes.com/1995/01/22/world/quake-in-japan-gangsters-gang-in-kobe-organizes-aid-for-people-in-quake.html This real life event]] arguably becomes a plot point in Chapter 9, as it partially explains Kyon's lack of real reluctance to [[spoiler:join the Yamaguchi-gumi]].
* NiceJobBreakingItHero: Subverted. Kyon initially thinks this is the case after accidentally informing Fujiwara that the latter cannot die until after traveling back to the previous Saturday, however [[spoiler:Fujiwara did a VillainousRescue on that day, so if he had not gone back in time due to Kyon's information, Kyon would have died.]]
** What ultimately makes Tachibana decide for [[spoiler:trapping Kyon halfway into Sasaki's closed space]] was Mori's [[ShameIfSomethingHappened implicit threat to her grandfather]].
*** Also she gets the idea from Fujiwara warning her not to do it.
* NoHuggingNoKissing: The ShowWithinAShow ''Brave Detective Sasha'' is an InUniverse example. Koizumi commented that fans are speculating that the last book of the series ''might'' depict a kiss between the main characters.
* NoJustNoReaction: Kyon does ''not'' want to think about the idea of being his shipped with Koizumi. [[YaoiFangirl Kanae does]]. [[RunningGag Repeatedly.]] It all comes to a head when the contents of her notebook are revealed, where even Koizumi can't resist joining in the teasing.
* NoodleIncident:
** Kyon travelled back in time to defeat 12 Yakuza single-handedly, complete with BadassLongcoat, and on the same trip did something that was said to have intimidated Mori severely. Later on, readers discover that Mori is extremely intimidating already, as seen in the PsychoticSmirk entry.
*** Subverted even later in Chapter 26 where the events are described in detail.
** In-universe, lampshaded example: In Chapter 45, Kuyou eats a plate of noodles far too fast (and did not yet understand the concept of chewing), and winds up choking. When Kyon gives her the Heimlich, she almost hits Achakura with a noodle. In the next chapter, Kyon turns it into a literal example of this by not "going over the noodle incident."
* NotADate: In Chapter 30, Mikuru tried to deny to Haruhi that her going to see a movie with Kyon and Yuki was a date, despite the fact that she asked Haruhi for permission about this appointment ''as a date''. Implicitly subverted, as [[spoiler:Haruhi and the rest of the girls explained her the plan to [[MarryThemAll share Kyon]], making the attempt to hide that it was a date a moot point]].
* NotSoDifferent: Kyon invokes this trope by name to Wataru, as they both want to protect their own sisters.
* NotSoStoic:
** In Chapter 30, Kuyou wants to help Kyon, and he sees the satisfaction in her eyes when he takes the weapon. She also wishes him good luck.
** Yuki after the events of Chapter 39. It's the first time that she's visibly ''scared'', trembling and asking Kyon to [[SecurityCling hold her]].
*** The above ''pales'' in comparison with her reaction to what happened next. Due to a misconstruction, [[spoiler:Kyon thought Yuki wanted to break up with him. At his pained acquiescence (he honestly thought [[YourCheatingHeart he didn't deserve any better]])]] Yuki realized her mistake and tried to clarify the misunderstanding, becoming more and more distraught over her self-perceived inability to express herself and clear things up. Her reaction was [[MeaningfulEcho very reminiscent]] of a particularly [[TearJerker tear-jerking]] scene from TheMovie where [[spoiler:Kyon returns the Literature Club application to disappearance!Nagato]].
---->'''Yuki:''' "Don't ... let me go..."
* NotWhatItLooksLike: Kyon's reaction after being photographed with Kanae sleeping against him and his arm around her (an absent movement, he does the same to his sister). Actually a subversion since who took the photo is just teasing him.
[[#O]]
* ObfuscatingInsanity: One batch of Yakuza decide that this is must be what Kyon is doing when he starts having a conversation with ShoulderAngels only he can see.
* OffScreenTeleportation: Kyon ''seems'' to pull off this trope from [[SympatheticInspectorAntagonist Miyuki]]'s [=PoV=]. In Chapter 60 and just around twenty minutes after the latest report of Kyon's activities in Nishinomiya, Miyuki sees him in person in Okinomiya, well aware of the fact that no form of transportation should be able to make such a trip in said timespan. [[spoiler:Explanation: The person sighted in Nishinomiya was in fact Kyon's future self.]]
* OhCrap: Kuyou's response when she accidentally creates an uncontrolled singularity in the middle of her [[PhantomZone Shadow Song]].
* [[OhCrapThereAreFanficsOfUs Oh Crap! There Are Doujin of Us...]]: The rest of the Brigade discover that some of Kanae's sketchbooks contain hentai doujin of them, such as [[{{Yaoi}} Kyon × Koizumi]], [[AThreesomeIsHot Haruhi × Kyon × Kanae]], etc.
* OhNoNotAgain: Sasaki's response to [[spoiler:Sumiyoshi-rengo's frequents attempts to kidnap her]].
* OlderThanTheyLook:
** Zigagged with. All participants of Yuki's training session have trained [[YearInsideHourOutside for about a year at least each night]] for weeks. However, Yuki [[LaserGuidedAmnesia deleted all their irrelevant memories]] except hers and [[FountainOfYouth reverted their aging process]]. So they don't remember anything except the results of training, even if they have lived all these years.
** Kyon time-travels so much, even he isn't sure how old he'd be at the end of everything.
** As a consequence of [[spoiler:Kanae using Mental Interdimensional Travel]], Haruhi believes she is quite a bit older than she thinks she is.
*** Kanae in general; her given age is sixteen, but she looks about the same as twelve year old Miyoko.
* OneDegreeOfSeparation: Let's see:
** It's all but stated that Miyoko's older cousin that she had a crush on ran off with Kyon's older cousin that he had a crush on.
** Haruhi's father is Kyon's father's direct superior.
** Tsuruya's bodyguard is [[spoiler:the son of [[VisualNovel/HigurashiWhenTheyCry Shion's]] [[http://whentheycry.wikia.com/wiki/Tatsuyoshi_Kasai bodyguard]].]]
** Itsuki turns out to be a huge fan of [[spoiler:Kyon's aunt Rena's books]].
** Ryuguu Ryo, the boy that Kyon fights, turns out to be [[spoiler:the son of the child produced by Rena's mother's cheating.]]
** Miyuki, the head of the investigation surrounding Kyon, [[spoiler:is Akasaka's daughter.]]
** Haruhi and Sasaki [[MythologyGag went to the same Elementary School]], although they never talked to each other.
** One of members of the Fujiya-tachi, Maruyama Iyouji, ended working in [[http://haruhi.wikia.com/wiki/Keiji_Yamatsuchi Yamatsuchi Keiji's]] model store, which was one of the two sponsors of the amateur movie filmed by SOS Brigade.
** Chapter 60 reveals that [[SympatheticInspectorAntagonist Akasaka Miyuki]] met [[spoiler:Kyon when he was a kid. She even babysat him a few times and Mion joked that she changed his diapers at some point.]]
* OneDialogueTwoConversations:
** In Chapter 22, Kyon and his father have a chat. Kyon thinks his father found out about his [[spoiler:criminal connections and activities]]. His father is actually talking about the [[spoiler:arranged marriage]] both families have planned.
** Also, in Chapter 11, Kyon mentions that he went to Nagato's place to [[spoiler:learn martial arts]]. Mori thinks they had sex. When Kyon mentions that he also slept in the same room as Tsuruya, Mori thinks that, they too, had sex. Kyon thus thinks that Mori is getting him armor because she starts moaning about it when he mentions he's going to meet with [[spoiler:20+ Yakuza in a CurbStompBattle]]. Mori instead gets him other forms of protection. Individually packaged, foil-wrapped 'protection'.
%% There is already an entry for the trope "One Hundred And Eight" for Tsuruya in the Characters' Page.
* OneLiner:
** [[DeadpanSnarker Kyon]] in Chapter 13: "Anyway, you were reminding me that I don't have a future?"
** Koizumi in Chapter 26: "I believe my point has been significantly punctuated."
* OneOfUs: [[CaptainObvious Well, duh?]]
* OneSideOfTheStory: The reason why [[spoiler:Yamane]] hates Kyon's guts. [[spoiler:From [[StalkerWithACrush Yamane]]'s [=PoV=], the events surrounding Asakura's murder attempt against Kyon looked a lot like a LoveConfession going ''[[QuestionableConsent wrong]]''[[labelnote:(to be precise)]]For Yamane, it happened like this: Ryouko leaves a note in Kyon's shoe locker, she walks into empty classroom and some time later Kyon follows suit, nobody else enters the room until eventually Taniguchi opens the door and promptly runs away while apologizing profusely (and yelling "take your time!" in the dub), Yamane leaves and misses Kyon and Nagato leaving the classroom and the next day their homeroom teacher announces that Asakura moved overseas with Kyon looking not one bit surprised at the news[[/labelnote]].]]
* OneSteveLimit: Averted due to the crossover. There are two characters named Keiichi: [[Characters/HigurashiWhenTheyCry Kyon's uncle]], and one of the Tamaru brothers.
** While Tsuruya is given a first name in this story, she's still nearly always referred to as "Tsuruya" by her friends, and her father is introduced in this story and ''also'' referred to by his last name, despite his first name being given. This leads to two characters both referred to as "Tsuruya," and if this story didn't use JapaneseHonorifics any scene involving both of them at once would be ''extremely'' confusing.
** Kyon's mother also shares her name with Shion and Mion's mother. This led to problems for her growing up.
* OperaGloves: Yuki's new costume has elbow-high gloves that act as an arm-version of ZettaiRyouiki.
* OrAreYouJustHappyToSeeMe: Parodied. After Kyon received his new PDA and [[AIIsACrapshoot deadpanned about it being like]] [[{{Terminator}} Skynet]], while the phone is still on his hand:
-->'''Tsuruya:''' Is that the end of the world in your pockets, or are you just happy to see us?
* OurHeroIsDead: Chapter 19 ends with [[spoiler:Kyon being shot]].
* OurLawyersAdvisedThisTrope: The author helpfully mentions in Chapter 31 that his LaserBlade is legally distinct from a [[StarWars lightsaber]].
* OutsideRide: Kyon hopped to the top of car while [[InvisibilityCloak stealthed]] in Chapter 45, keeping himself in place thanks to his [[GravityMaster gravity manipulators]].
[[/folder]]

[[folder: P-R]]
[[#P]]
* PaperThinDisguise: Kyon calls Tsuruya and claims he's his uncle Kintaro. Justified because [[TimeTravel he was asleep with her at the moment,]] though she remarks they have the same voice.
* ParentsAsPeople: Kyon's parents. [[spoiler:Also Sasaki's mother.]]
* ParentsWalkInAtTheWorstTime: {{Defied}}. [[GenreSavvy Yuki]] [[MagicFromTechnology installed a program]] in Kyon's bedroom that prevents this trope from happening by teleporting his guests out of there if someone is about to discover them. On the flip side, this preventive measure sometimes causes [[InconvenientSummons Inconvenient]] [[InvertedTrope un-]][[InconvenientSummons Summons]].
* PassThePopcorn: In Chapter 60, Yuki and Kuyou chose to sit back and enjoy their tea & cookies while quietly and attentively observed how their friends [[spoiler:convinced Kyon and Sasaki to hook up.]]
* PerceptionFilter: Yuki learns how to generate an "occlusion field" from her observations of Kuyou's powers. She uses it in Chapter 51 to make Kyon and herself "difficult to focus on or remember to most bystanders". If Kuyou boosts her efforts, this cousin of the "[[Literature/LifeTheUniverseAndEverything S.E.P. field]]" is powerful enough for her to [[spoiler:make out with Kyon]] in the middle of the street with no one but them (and potentially other Interfaces) noticing a thing.
* [[spoiler:PerfectlyArrangedMarriage]]: Initially resisted due to risk of apocalypse, but all involved parties come around to the idea quite quickly.
* PhantomZone: Kuyou utilizes her "Shadow Song" as sandbox of sorts, where she can allow herself to use her powers to a greater extent without [[EarthShatteringKaboom destroying the Earth]] by mistake and more importantly [[spoiler:to act as a buffer space where the Combine forces and other extra-dimensional harmful influences can be deal with before they can affect the real universe]].
** It's also useful for practicing baking cookies. On a stellar scale.
* PhlebotinumAnalogy: [[spoiler:Achakura]] [[SureLetsGoWithThat explains]] that having a costume that protects you and operates on principles most people won't understand, and wielding equipment that few on Earth have ever seen, let alone held ''is'', in fact, much like turning into a MagicalGirl.
* PhoneyCall: Cleverly {{invoked|Trope}} in Chapter 15. When Rika wants to speak with [[NotSoImaginaryFriend Hanyuu]] in the presence of people [[InvisibleToNormals who can't see or hear her]], she wears an ear-piece and simply talks with her, deliberately giving the impression that she's just having a conversation by phone.
* PimpedOutDress: After Haruhi declares they can take turns at mascot duty, Tsuruya ends up wearing one of these, as does Yuki.
** Tsuruya also has a collection of formal kimonos with elaborate designs and enough layers and accessories to require at least one other person's help to put them on.
* PinkySwear: Kyon's sister promises her brother not to tell Haruhi [[spoiler:Tsuruya kissed Kyon]]. While Kyon's sister didn't tell Haruhi, she acknowledged it's her fault Haruhi learned that because she slipped when talking with a cousin.
** Yuki initiates one after Tsuruya asks her to promise to tell her if she ever needs anything [[spoiler:in return for helping her confront the boss of the Sumiyoshi-rengo group responsible for all the kidnapping attempts and attacks against Kyon.]]
* ThePlan: Kyon suspects Ryouko had one, after he finds out that Yamane was being controlled by Ryouko via her [[spoiler:bloomers]]. Yuki thinks that Yamane was just stupid enough to accidentally corrupt the data inside, accidentally letting Ryouko control him.
* PocketDimension: The daily training sessions take place in one.
* {{Polyamory}}: [[spoiler:Keiichi and Kyon's aunts.]] They even have the schedule in the closet. [[spoiler:Haruhi is ''actively angling'' toward this exact setup with the other female members of the SOS-Dan]].
* [[PoorCommunicationKills Poor Communication Gets You Engaged]]: When Kyon's dad asks him about joining Tsuruya's family, Kyon mistakenly thinks he means the Tsuruya crime family. Had Kyon and Yuuto not been talking cross purposes, there is a chance that the engagement could have been stopped. Luckily it all worked out in the end anyway.
* PornStash: Kyon deleted the one on the SOS Brigade computer. He now has a small one in his phone, courtesy of Mikuru and Tsuruya.
* PostKissCatatonia:
** The one who provoked the ForcefulKiss example above took a few moments to recover from it.
** [[spoiler:Adult!Mikuru]] also pulls this off on [[spoiler:Kyon]].
** In Chapter 28, [[spoiler:Kyon]] pulls this on [[spoiler:teen!Mikuru]], with the latter also "suffering" FootPopping.
* PowerIncontinence: In order to keep Haruhi's power from affecting the world randomly, Yuki has to work full-time as control mechanism for them; however, closed space still occurs and Yuki has to clear junk data periodically. [[spoiler:After the MemoryGambit closed space stops happening but Yuki still has to control Haruhi's power full-time.]]
** [[spoiler:Later chapters reveal that Haruhi has been steadily producing less and less junk data, probably as a result of her growing emotional stability, to the point that Yuki asked her to come with them to a training session so the TimeDilation would help to accelerate the relative production rate of the data that Yuki uses to maintain her PocketDimension.]]
* PowerOfFriendship: A recurrent element through the story, especially after Kyon is shot.
* PowerOfTrust:
** This is what moved Haruhi into [[TakeAThirdOption taking a third option]], preventing her HeroicBSOD.
** The older Mikuru's WorldOfCardboardSpeech is based on this.
* PowerPerversionPotential: A very mild example: It's been pretty much confirmed in story that during Yuki's [[YearInsideHourOutside training sessions]], she used some of that time to [[spoiler:make-out with Kyon]].
-->'''Kyon:''' Um ... what ... do you get out of this, exactly? I know to us, we each go ... somewhere else to practice. What about you?\\
[=*=]Yuki says nothing and blushes*\\
'''Kyon:''' *realization hits* A...actually, forget about that for now.
** In Chapter 28, with over a month of training sessions:
--->'''Haruhi:''' *[[GivingSomeoneThePointerFinger pointing to Yuki]]* Kyon got so good [[spoiler:at kissing]] because of ''you''!\\
'''Yuki:''' That is probable. However, I have no comparable metric for comparison. But I do find the sensation ... very enjoyable.
* PowerUpFood: In Chapter 59, it's revealed that [[spoiler:Hanyuu can still materialize herself as she did in the last arc of ''VisualNovel/{{Higurashi|WhenTheyCry}}'', but she normally lacks the energy to do it. Noticing this, Kuyou decided to provide Hanyuu with additional "spin" for her to "shape" by imbuing it in the cookies Kuyou gave to Hanyuu.]]
* PowerUpMagnet: A rare non video game example. In Chapter 61, [[spoiler:Kuyou in her chibi-mode flew around Kyon and]] collected what amounts to the power cores of defeated [[spoiler:Striders]]. This is a double-aimed tactic: it precludes their enemies from reusing that energy and the resources so obtained can potentially be repurposed.
* PreAssKickingOneLiner: Subverted in Chapter 38. Just after Kyon delivers the line to three {{yakuza}}, he gets teleported out of there.
-->'''Kyon:''' "I'll respect that you're cutting to the chase; let me return the favor in kind!"
* PsychicBlockDefense: Haruhi, Yuki, Mikuru and [[spoiler:Kyon]] blocks their mind from Koizumi.
** Haruhi's block feels like a strong wind that prevents him from approaching.
** Yuki's block feels like a wall, though he still can detect her presence.
** Mikuru's block is more solid, and haphazard than Yuki's and more than enough.
** [[spoiler:Kyon]]'s block prevents Koizumi from even detecting his presence. [[spoiler:Not even Haruhi running her powers in safe mode can bypass it.]]
* PsychoticSmirk: All the Yakuza can do it, mainly because it implies that they can give you hell. Mori's smirk, on the other hand, can cause fear-induced paralysis, as seen in Chapter 22, and she isn't even a Yakuza.
* PunchCatch: {{Averted|Trope}} and {{discussed|Trope}}. The first time Haruhi watched Kyon fighting she wondered why he yanked his opponent's fist to the side instead of stopping it entirely. A second later she realized Kyon took advantage of the mook's strength to slam his solar plexus and shoulder-throw him against the concrete ground in a single movement.[[#Q]]
* QuizzicalTilt:
** Tsuruya when Kyon received a greatcoat as a gift from Mikuru, and realized it's the same coat she saw [[TimeTravel him wearing some weeks ago]].
** Mikuru in Chapter 30's FuroScene when [[spoiler:Haruhi is explaining the plan to [[MarryThemAll share Kyon]]]].
[[#R]]
* RagnarokProofing: The dimensional anchor worked perfectly fine in spite of being millions of years old.
* RankInflation: Tsuruya gave an S rank to Kyon's speech when she asked him if she should learn about the supernatural in the SOS Brigade.
* RecurringExtra: There's an unnamed underclassman of Kyon who [[RunningGag usually runs into him]] at inopportune moments, like [[GoodCopBadCop interrogating a member of an illegal photography ring]] and talking how breaking a {{Yakuza}} thug's hand was the most impressive display of a fight.
* RedPillBluePill: Kyon gives Tsuruya the option to either learn the truth behind the SOS brigade and the supernatural, or remain 'just a side character.'
* ReferenceOverdosed: Mainly to trope names.
** An avid ''VisualNovel/HigurashiWhenTheyCry'' fan would also catch the multiple subtle references to Higurashi, even in chapters that have nothing to do with Hinamizawa.
* RefugeInAudacity: And its buddy, RuleOfCool, are the two primary forces responsible for keeping Kyon from becoming a MartyStu.
* RetCon: There have been a few, mostly involving the author changing the names of certain characters. The original first name he gave Tsuruya was Kaede, but changed it to Haruka because he liked [[MeaningfulName its meaning]] better. He was also originally mistaken about the name of [[VisualNovel/HigurashiWhenTheyCry Akasaka's]] daughter, and fixed the mistake (Momoko to Miyuki) once he was informed. Also, back when he thought that "Sasaki" was the character's given name, the surname he chose for her was Matsumoto. He changed that to a RepetitiveName in order to TakeAThirdOption.
* RetGone: Narrowly avoided for [[spoiler:Kyon, involving Closed Space, TimeTravel and Kanae's sliding]].
* RetroactivePreparation: Kyon uses and abuses this trope.
** Need a dimensional anchor quickly and you just realized your friend who doesn't know of the supernatural may have it? Go to a day before and ask her to deliver it a few seconds after you realize that.
** He also time travels several days back to prepare countermeasures when [[spoiler:Sasaki is kidnapped]].
* TheReveal: Kuyou explaining how Sasaki's powers are expressed, that being [[spoiler:a PowerNullifier of everything she doesn't believe possible on anything she can observe]].
* RevengeByProxy:
** The voyeur ring was originally a plan set by [[spoiler:Yamane]] to get embarrassing pictures of [[spoiler:Haruhi]] and through her enact revenge on [[spoiler:Kyon for what Yamane thinks he did to Asakura.]]
** Some men from a foreign country killed Tsuruya's mother to get revenge on [[spoiler:her sister, Shinobu.]]
* RightForTheWrongReasons: Several cases, typically due to people on either sides of the {{Masquerade}} trying to predict the actions/reasons of others in what's on the way to becoming a ThirtyXanatosPileup.
* RomanceInducingSmudge: In Chapter 62, [[spoiler:Kanae]] plucks up a grain of rice from Haruhi's cheek, winks to her and then carefully licks it from her fingertips. A blushing Haruhi is left speechless for moment and first thing she does after finding her voice again is actually to ''congratulate'' her for getting the flirting upper hand.
* RomanticTwoGirlFriendship: [[spoiler:Haruhi and Kanae]], or so [[TheBeard they want everyone in Kitago to think]].
* RoofHopping: In Chapter 26, [[spoiler:after getting a powerup which allowed him to control gravity, Kyon]] started jumping from roof to roof for the fun of it, discovering in the process that it was a fast, inconspicuous and energy-efficient way of movement.
* RunningGag:
** "I am keeping this picture."
** Also the content from the letters from the future.
--->'''Haruhi:''' Can I go (time travelling) with you?\\
'''Kyon:''' (reading his first letter) "No, she can't."
** Also Kyon's dual habits of saying his future self is annoying and then mocking his past self's incompetence, in addition to saying 'hi' to himself.
** Kyon thinks that he has a very special hell waiting just for him.
** Every time an adult has an important conversation with Kyon, he initially thinks they're accusing him of being a {{Lolicon}}.
*** As a slight variation on the gag, Kyon's uncle asked about his relationship with his female friends in one such conversation, and Kyon interpreted it as asking if he was gay.
---->'''Kyon:''' Don't get the wrong idea. I like girls just fine. That is ''not'' the problem.
** Kyon keeps telling himself that Shinobu, the Tsuruya family maid, is a ninja.
** Cookies being Suou Kuyou's TrademarkFavoriteFood.

[[#S]]
* SacredFirstKiss: In Chapter 30, Kanae asks Kyon to be her FirstKiss. Interestingly enough, it's him who makes a bigger deal of it by pointing out that "[he's] not sure [he's] the kind of guy [she wants] to waste something that precious on".
* SaidBookism: The characters ''allow'' and ''offer'' a whole lot more than they ''say''.
* {{Sarashi}}: Mentioned by name as part of Sasaki's cosplay during the FlashMob.
* SarcasticConfession:
** At the end of Chapter 9, [[spoiler:Kyon joins the Yamaguchi-gumi as an honorary member.]] When his mother asks if he's through being a delinquent (which wasn't his fault in the first place), he answers that he's moved on to joining the Yakuza. His mother doesn't believe him. Obviously.
** Also, Kyon mentions casually to Sasaki that he has to meet several past instances of people, fight 12 thugs at once, arrange to deliver an alien artifact and [[ArsonMurderAndJaywalking study for a math test]]. It scares the crap out of adult Mikuru, but Sasaki doesn't take it seriously.
** Inverted in Chapter 30, Sasaki tells Haruhi about the Anti-SOS Brigade's identities. Sasaki thinks that they're delusional or pulling her leg, but Haruhi is now aware of enemy espers, time travelers, and aliens, since immediately after hearing this she wants to speak with Koizumi.
* ScareEmStraight: Tanaka Taro in chapter 54 begins his short time in the story reflecting to himself that he is going to become an important and powerful person by taking out Kyon. After the attempt, he reflects that after he recovers, he will still become an important and powerful person by working at the docks, getting the Japanese equivalent of a GED, and working his way up to management.
* SceneryCensor: During Kyon's first FuroScene at his uncle's house, [[spoiler:Hanyuu]] notes that hers and [[spoiler:Yuki]]'s linked hands (long story, ItMakesSenseInContext) would prevent anyone standing at the doorway from seeing his "most interesting areas".
* SchoolUniformsAreTheNewBlack:
** Kyon keeps falling into this and just when it looked like he'd got something to replace his uniform, he ended up wearing the uniform as well as his default.
** Nagato seems to have gotten out of this. Well, if she wears any of the clothes she and Mikuru bought.
* TheScottishTrope: In Chapter 44, during the POV of one of the Sumiyoshi-rengo, at one point he refers to Kyon as '[[SuspiciouslySpecificDenial the boy who he absolutely had not heard the name of]].' This was immediately after Yuki said something that 'not a single man would acknowledge what they had heard.'
* TheScream[=/=]ScreamingAtSquick: Haruhi when Tsuruya shows her the pictures of her investigation. Later Yanagimoto Ai when she's shown the same pictures.
* ScrewYourself: Implied that Kyon dreamt of a situation involving Mikuru and this trope. He cuts himself off though...
* SecretKeeper:
** Rika managed to be one for Kyon's supernatural adventures [[InternalReveal by revealing]] [[VisualNovel/HigurashiWhenTheyCry her own story first]].
** [[spoiler:Miyoko (who went by Miyokichi in the novels)]] after she gets to know about Kyon and time travelling.
** Kyon's sister is aiming to gain enough trust from her brother to become one.
** In Chapter 51, [[spoiler:Sakanaka and Yanagimoto]] aren't convinced that [[spoiler:Haruhi and Kanae]] are really in a RomanticTwoGirlFriendship and try to get [[spoiler:Haruhi]] to explain what's really going on. [[spoiler:Haruhi eventually reveals to them the plan for a MarryThemAll arrangement between Kyon the rest of the girls in the Brigade. Both girls promise to keep it secret.]]
* SecurityCling:
** Haruhi tries to invoke this trope in Chapter 19 by having Kyon take Mikuru to see a [[{{Film/Saw}} gory movie]]. Mikuru ends up in Kyon's lap, with Haruhi clinging to one arm and Miyoko clinging to the other.
** In Chapter 35, Kyon's sister is invited to a special showing of the [[ShowWithinAShow movie]] "JustForFun/TropeTan Begins", but she gets scared of the crowd of reporters covering the event and their flashing cameras and runs up to grab his brother's hand.
* SempaiKohai: Kyon and Kanae. [[spoiler:And as of Chapter 32, Suzumiya-sempai as well.]]
* SexByProxy: [[DownplayedTrope A mild version]], more like "Kiss by Proxy", but the same principles apply:
** In Chapter 29, Koizumi was uncomfortably [[TheEmpath aware]] of Haruhi's emotional state while she and Kyon were kissing. [[spoiler:A few chapters later, after Koizumi informed Haruhi of this, the very first thing she did was to sever her PsychicLink to him and the rest of the Organization's [=ESPers=].]]
---> [[spoiler:"Um, yeah, well.... I'd really like to make it so that you would stop being stuck reading me! As brigade chief, I think I deserve mental privacy!"]]
** Kuyou and Achakura frequently share data and insights in their attempts to bridge the communication gap between their vastly different forms of sentience. Cue Chapter 57, where [[spoiler:Kuyou apparently didn't see nothing wrong with leaving an open channel for Achakura to "access" what she was feeling while she and Kyon kissed. It's currently unknown (as of Chapter 57) what Achakura thought of the experience.]]
** In Chapter 60, it was [[spoiler:Kyouko]]'s turn to perceive the sensations and emotional responses from [[spoiler:Sasaki when she and Kyon]] were kissing. With two interesting twists: [[spoiler:1) Koizumi was with Kyouko at that moment and he was able to ''accurately'' recognize what was going on thanks to [[TheEmpath psychic powers]] and [[BrickJoke his previous experience]] [[OhNoNotAgain on the matter]], resolving to talk to Kyon "most sternly" about it and 2) Thanks to the fact that the episode took place shortly after her RelationshipUpgrade with Koizumi, Kyouko resorted to a simply and effective approach to deal with the situation: {{glomp}} her boyfriend and [[BigDamnKiss kiss him passionately enough]] to be unable to tell between her own feelings and Sasaki's.]]
** There is the implication that this trope was played straight in [[spoiler:[[VisualNovel/HigurashiWhenTheyCry Rika and]] [[NotSoImaginaryFriend Hanyuu]]'s case, as it follows from the FridgeLogic of what would happen with their [[{{Synchronization}} shared senses]] after Rika grows up.]]
* ShipperOnDeck:
** Most of the girls in the [[FanNickname Big Damn Harem]] ship each other with Kyon, but Haruhi makes a conscious effort to do this.
** [[NinjaMaid Shinobu]] ships Kyon/Tsuruya and makes a point to remind him to spend time with her and keep things with the other girls as discreet as possible. [[spoiler:Shinobu even scored an OffscreenMomentOfAwesome by convincing Tsuruya's father, a major yakuza boss, to turn a blind eye to the whole situation after he was informed about it.]]
** Kyon's mother also ships Kyon/Tsuruya, to the point of [[spoiler:arranging an ''Omiai'' (Japanese formal marriage interview) for them with Tsuruya's father's help.]]
** Sasaki's mother unsubtly encourages her daughter to date Kyon. [[spoiler:Actually a {{Deconstruction}}: The former had to raise Sasaki alone because Sasaki's father abandoned them and she doesn't want the same fate for her daughter. For this very same reason, she approves Kyon because she mistook him for a spineless guy whom Sasaki would be able to keep under her thumb and at her side if they ever hooked up.]]
* ShipSinking: Subverted in Chapter 39. Yuki comments "It is not ... mutual" when Kyon stayed to comfort her (Yuki had to save Kyon from something that makes her afraid). After Kyon's answer - he believed she was talking about their relationship and even had to give ''himself'' a BetterAsFriends inner monologue - Yuki explains that what she really wanted to say is that her own actions aren't on par of what she expected Kyon to do.
* ShipTease: Kyon is teased with most single female characters. Especially Kanae, who has dated Kyon before in an AlternateUniverse.
* ShoutOut: There's a ton. So many so that we've set up [[ShoutOut/KyonBigDamnHero a page for them]].
* ShowWithinAShow: There is a JustForFun/TropeTan anime and movie.
-->'''Trope-tan''': Chekhov ... BEEEEEEAM!
** Also "Brave Detective Sasha" novel series, written by Rena.
* ShuttingUpNow:
** In Chapter 36, after Kyon notes Haruhi's too calm reaction to her learning Kanae [[BedmateReveal involuntarily teleported herself to Kyon's bed during the night]].
--->'''Kyon:''' Part of me wants to say that your reaction to this is incredibly unreasonable. Rather, only you would look at something so incredibly unreasonable, and choose to be so reasonable about it.\\
'''Haruhi:''' (gives a pointed look to the other person in the conversation) I'm the only one who's reasonable? What about your [[ArrangedMarriage fiancée]]?\\
'''Kyon:''' I am going to forgo speaking privileges for the rest of the day.
** In Chapter 51, after Yanagimoto utters an [[ThatCameOutWrong oddly worded]] sentence.
--->"Yeah, but I can't let Tani-baka know about this -- ever," Yanagimoto said, shaking her head. "The second he heard about it, his head would explode!" She blinked, thinking about what she just said as her face reddened. "And I'm going to shut up now," she muttered, reaching for her slightly melted sundae.
* SillyMeGesture:
** Tsuruya in Chapter 14 when she had to explain about "kinship rituals" to Haruhi.
** Adult!Mikuru in Chapter 24 when she told Kyon she lost certain photo of hers.
* [[TheSlowPath Slow Path]]: Kyon is sent about half a day back in time so he could help Tsuruya (and then staying at her house) while being grounded without trouble. Future Kyon had to stay the night at home.
* [[BigBlackout Small Blackout]]: To Hinamizawa. Apparently happens a lot.
* SoGoodWeMentionedItTwice: Taniguchi's opinion about Kyon's rise to popularity/notoriety in Chapter 13:
--> '''Taniguchi (to Kyon):''' "I mean, the ladies love you, you've rounded up all the best looking ones into your club, your grades are coming up, the ladies love you, word on the street is that you've been regularly fighting crime in dark alleys or something, super-hero style, the ladies love you, you're a badass martial artist now, the ladies love you, you were a super-athlete in physical education today, the ladies love you.... Just that last point alone should satisfy any normal, healthy male, right?"
* SoundEffectBleep: In the form of a car horn when Fujiwara calls Tachibana a bitch.
* SquareCubeLaw: The robot Kyon fought violates that law with its spindly legs.
* {{Squick}}: In-universe example: this is Kyon's reaction to Yuki taking the remnants of Ryoko's data for future use. [[spoiler:From Ryoko's old bloomers.]]
* StableTimeLoop: There's one every few chapters.
** Also, due to the nature of time loops and causality, Kyon knows the only thing preventing the IDSE from getting revenge on him for making Yuki disconnect is the fact that he's involved in several loops, and killing him might cause tons of trouble to time.
---> "I'm putting that off for now," he said with another shrug. "I need to keep a time loop open to occupy the IDSE anyway."
* StealthPun:
** Chapter ''Eleven's'' name is ''Yeah, It Went There'', as it's saying this chapter will get... UpToEleven.
** Chapter 62 is titled "{{Faint|ing}} Acknowledgment".
* SuperCellReception: Kyon's phone can send and receive some calls even when he's not technically on ''Earth''. [[spoiler:Justified: Yuki prepared two sets of [[http://en.wikipedia.org/wiki/Quantum_entanglement paired particles]] in both of their phones so they could keep in contact regardless of the distance or the availability of human networks. Averted with regular phone calls, which caused some troubles in Chapter 55 when both of them were in Kuyou's [[PhantomZone Shadow Song]] and couldn't be informed about Haruhi and Sasaki's kidnapping for most of the girls' ordeal.]]
* SuperWindowJump: [[spoiler:Kyon does this]] in the Initial Conflict arc [[spoiler:whilst holding a spy.]]
* SureLetsGoWithThat: When Kyon [[WeHaveForgottenThePhlebotinum accidentally leaves his coat and equipment behind in his sister's room]], [[spoiler:Achakura]] tries to get [[spoiler:Nonoko]] to bring it to him as expediently as possible. During the course of [[spoiler:Achakura's]] explanation, she resorts to this trope to avoid wasting time with additional explanations.
-->'''[[spoiler:Nonoko]]:''' And it's going to [[JumpedAtTheCall turn me into a magical girl]]?\\
'''[[spoiler:Achakura]]:''' For values of 'turning you into a magical girl' equal to 'you having a costume that protects you and operates on principles most people won't understand, and wielding equipment that few on Earth have ever seen, let alone held,' yes, this will turn you into a magical girl!
* SurpriseParty: Chapter 60 ends with almost all the girls in the SOS Brigade welcoming Kyon to his birthday party at Mion's house.
* SuspiciouslySpecificDenial:
** [[spoiler:Hanyuu watched Kyon while he was bathing because he disappeared the night before.]] She had no ulterior motive to keep an eye on him, or admire his surprisingly toned physique as he patiently watched over one of his younger cousins. She was just ensuring he was okay, unhurt after the mysterious events, and that was the only reason she was staring at him so closely!
** Kanae swore that her sliding into Kyon's bed and sleeping with him was a complete accident. Haruhi lampshades her constant InnocentInnuendo around Kyon.
--->'''Kanae:''' I didn't mean to fall into Sempai's bed! We weren't sleeping together on purpose - it was an accident!
** Chapter 55[[spoiler:, during the escape from their yakuza captors:]]
-->'''Haruhi:''' Close your eyes!\\
[=*=]Haruhi tears open a chain-link fence in their way with {{telekinesis}}*\\
'''Sasaki:''' *opens eyes* What-- What just happened?\\
'''Haruhi:''' Something ''completely'' plausible.
* SweatDrop: Mikuru after telling Haruhi about when Kyon accompanied her buying cloth and a sewing machine.
* SwitchingPOV: Changes in character focus are signaled by a break.
[[#T]]
* TakeAThirdOption:
** Haruhi can't unbottle her feelings about the consequences of her powers because it will cause even more strain to others, and she can't ignore it either because she cares about the SOS Brigade. In order to prevent an HeroicBSOD she [[spoiler:runs a MemoryGambit on herself so she doesn't destroy the world on an accidental whim.]]
** [[spoiler:What do you do if you are part of an UnwantedHarem but don't want anybody to lose? MarryThemAll!]]
** WordOfGod said that the story [[CuttingOffTheBranches follows]] a ''Higurashi'' plot called "Mitsuhoshi-hen", which literally translates as "third-way chapter," in reference to the fact that the version of ''Higurashi'' considered "canon" for this story, rather than following one of the two "official" endings[[note]]''Matsuribayashi-hen'' and ''Miotsukushi-hen''[[/note]], is a combination of ''Matsuribayashi-hen'' and various elements from the other ''Higurashi'' arcs.
* TalkingInYourSleep: In Chapter 3, Yuki teleports Kanae, Mikuru and Kyon into her home. Kanae was asleep throughout the teleportation and starts talking in her sleep.
-->"Mmm, Sempai," Kanae murmured in her sleep with a quiet giggle.
* TheTapeKnewYouWouldSayThat: Future Kyon likes to do this with his instructions to Past Kyon, probably since it helps avoid spoilers.
-->'''Haruhi:''' Can I go [back in time] with you?\\
'''Kyon (reading note):''' "No, she can't."
* TeleportInterdiction: In Chapter 63, [[spoiler:the SOS Brigade figures out how the Combine tracks down Kanae across dimensions but they also discover that they can't suppress or alter the "signal" without hurting her. In the end, they manage to set up an "Echo" on Kyon so the Combine will be forced to target his location instead of Kanae's.]]
* TemptingFate:
** Sure, Kyon, name the piece of sophisticated technology capable of self-advancement and created from the data remains of AxCrazy Asakura Ryouko [[{{Terminator}} Skynet]]. [[SarcasmMode What could possibly go wrong?]][[note]]Note that Kyon is expecting it to betray him. It also got itself hooked up to the Internet already.[[/note]]
** In the beginning of Chapter 31, Koizumi muses that he is the most normal among the extended SOS Brigade. He soon realizes he can use his powers outside closed space.
* ThatCameOutWrong:
** When Tsuruya and Kyon are disguising themselves as students of another school:
--->'''Tsuruya:''' Now, Kyon-kun, can you get on your knees?\\
'''Kyon:''' *shrugs* Somehow, I really expected to hear that from Haruhi, first.\\
[=*=]beat*\\
'''Tsuruya:''' *chuckles* I have to do your hair.
** Haruhi's InnocentInnuendo in Chapter 63.
* TheyFightCrime: She's a wealthy [[{{Yakuza}} heiress]]. He's a [[KidWithTheLeash role model]] for a [[RealityWarper so-called goddess]].
** Sasaki also briefly fantasizes about doing this, [[BrainsAndBrawn with her as the Brains to Kyon's Brawn]], before giving herself a reality check. [[spoiler:After all, if that ever happens, they would be technically criminals too because of Kyon's ties with the [[NeighbourhoodFriendlyGangsters Tsuruya family]].]]
* TheThingThatGoesDoink: There's one at the restaurant where Tsuruya and her father invite Kyon's family for a formal dinner in Chapter 28.
* ThoseTwoGirls: Sakanaka and Yanagimoto to Haruhi.
* AThreesomeIsHot[=/=]OneTrueThreesome: One of Kanae's hentai doujinshi features herself, Haruhi, and Kyon.
** Kyon gets a real one with Haruhi and Tsuruya in Chapter 54; even if it's only making out.
** Implied to have happened between Keiichi, Rena, and Mion after tying in one of their card games.
* ThrowingDownTheGauntlet: Wataru gives one to Kyon by causing what seemed like a small earthquake and shouting "Kyon! Face me!" that probably everyone in Kitago could hear.
* TimeBomb: The IDSE gives Yuki advance warning of her impending deletion in Chapter 1, and she periodically gives countdown times in the conversation with the Brigade.
* TimeMaster: In his duel with Koizumi, Fujiwara seems to speed himself up.
* TimeyWimeyBall: Kyon describes his view of time this way, using the exact same words as [[Series/DoctorWho the Doctor]].
-->'''Kyon''': I mean, for the most part, it's just kind of a...I don't know...[[ShoutOut a great ball of wibbly-wobbly, timey-wimey...stuff.]]
* TiredOfRunning: One FictionalDocument refers to what to do in this case.
* TooDumbToLive: Haruhi thinks that of Taniguchi. He doesn't realize that using his scale in front of Haruhi to rate Kanae an A- would arouse her curiosity. And that Kyon would most probably explain it cynically. And that Haruhi might be offended to find out Taniguchi's view of girls.
-->'''Kyon''': Taniguchi's a living perv-wiki. He's rated all the girls on a grading scale and only learns the names of those who get an 'A' or better.\\
'''Haruhi''': ''[turning to Taniguchi]'' Oh? I wonder what I ranked on that scale. Too bad you didn't even make fifteen minutes on mine.
* TooMuchInformation: By Kyon's request, Koizumi explained that he gained his ESP powers when both he and Haruhi were undergoing puberty. At the beginning, he found it extremely difficult separating their feelings at first, which led to highly awkward situations. Kyon realizes his mistake and declares that he never wants to clarify that.
* TrespassingToTalk: A variation. Thanks to his InvisibilityCloak, Kyon in two opportunities sneaked into [[spoiler:a police station to talk to people locked up in the cells. The first time, he accompanied Yuki who needed to be in close proximity to Yamane to purge the corrupt data that was affecting his mind. The second time, Kyon broke into the detention block alone to speak with the leader of the Fujiya-tachi and negotiate their possible admission into the Yamaguchi-gumi.]]
* TrickedOutTime: After Fujiwara declares that he is effectively immortal until he travels back in time to the beach in Calm Before The Storm, [[DiscussedTrope Kyon takes out his PDA, scans him, and notes that he now has a perfect image: since Kyon wouldn't know the difference back then, he just made "killing Fujiwara" a viable option again]]. Mikuru thus wonders whether she could alter time by changing events as predetermination is set by observations and records.
* TriggerPhrase: Kyon is given one if he needs to revert the MemoryGambit.
* {{Troperiffic}}: Need it be repeated what it has crossed over with?
* TheTropeWithoutATitle:
** Haruhi's favorite website is never mentioned by name. However, as it's mentioned it's a wiki, it inspired the JustForFun/TropeTan [[ShowWithinAShow anime]], and has an entry for HeadPet, [[TvTropes the name of this website]] isn't exactly a mystery for the reader.
** There's also a computer videogame series Haruhi likes, which apparently has LoadsAndLoadsOfCharacters and earned Kyon's complains on [[BulletHell having too many bullets]]. The name of the [[VideoGame/{{Touhou}} videogame series]] nor any characters are mentioned.
* TrueCompanions: Of course, the SOS Brigade are these. Everybody, including Tsuruya and Kanae was relieved when Kyon woke up from his [[spoiler:gunshot-caused unconsciousness]]. Kyon even points this out.
* TrustPassword: The story starts by Kyon using his TrustPassword so Haruhi can believe him and help Yuki.
* TVTropesWillRuinYourLife:
** Kyon's optimism and interest in the supernatural was destroyed by Sasaki's incessant [[{{Deconstruction}} deconstructionism]]; likewise, Sasaki's automatic {{Deconstruction}} of the PowerOfLove appears to have been what ruined her relationship (and chances of romance with) Kyon.
** It also occasionally causes Haruhi difficulty when it comes to explaining things.
** [[spoiler:Achakura]] thinks it might eventually become sentient. She doesn't expect it to be very sympathetic to her, but until then, she finds it helpful for understanding human culture.
[[#U]]
* UnbrokenVigil: After Kyon [[spoiler:had a bullet surgically extracted]], [[TrueCompanions Haruhi, Yuki, Mikuru and Tsuruya]] stayed the night in the hospital keeping him company, even if Yuki had already healed him. As a bonus, both Haruhi and Yuki sleep in the bed with him.
* UndeadTaxExemption: The slider always had a complete identity in every world she visited, including school records, friends and family. Later it's deconstructed when it's revealed that [[spoiler:she slides mentally, replacing or [[FridgeHorror overwriting the local Kanae with her]] thus never needing to have an identity-- she uses the local Kanae's]]. She doesn't realize it.
* UnPaused: A rare mundane example. When Mikuru begins to stitch Kyon's wound in Chapter 45, she forgets everything else. When she's done she completes her sentence.
* UnrequitedLoveSwitcheroo: It's revealed Kyon had a crush on Sasaki in their backstory ([[ObliviousToLove not that any of them realized that at the time]]). Now Sasaki [[LoveEpiphany has realized her own crush]] on Kyon (he has already gotten over his), who is [[ArrangedMarriage set to be wed to Tsuruya]] [[spoiler:and to be part of a MarryThemAll scenario]].
* UnstoppableRage: [[spoiler:Haruhi especially, coming dangerously close to killing people when Kyon is in danger. Kyon is prone to this as well when anybody from the SOS Brigade is threatened.]]
* UnusuallyUninterestingSight: Kyon's response to [[spoiler:Haruhi remaking the world again.]]
--> '''Kyon:''' (yawning) This again?
* UnwantedHarem: Deconstructed and reconstructed [[spoiler:in the [[VisualNovel/HigurashiWhenTheyCry Higurashi]] cast backstory.]]
* UnwittingMuggleFriend: Subverted with Yanagimoto and Sakanaka. Even though Haruhi went out of her way to keep them LockedOutOfTheLoop about the supernatural without outright cutting ties with them, they figured out that the SOS Brigade was involved in something dangerous and secret. However, they also realized that Haruhi's actions implied that she most likely wanted them as a [[MuggleBestFriend real link to the more mundane facets of her life]], so they decided to become her {{Secret Secret Keeper}}s (in a [[IDoNotWantToKnow willfully unaware]] manner) and help her wherever else they could.

* VerbalBackspace: After Kyon receives a greatcoat as gift from Mikuru in Chapter 21:
-->'''Kyon:''' I won't be able to get much use out of this until next winter, but I know once I do, I will greatly appreciate this! Asahina-san, I don't know what I've done to deserve such a fine present, but I am very grateful.\\
'''Tsuruya:''' I've seen that coats before. [[TimeTravel You had it on when you beat up those Sumiyoshi-rengo fellows who hurt Kasai!]]\\
'''Koizumi:''' Y...yes. I've seen that once before, as well, that day you left even Mori-san impressed.\\
'''Kyon:''' Or, you know, maybe even sooner than that.
* VerbalTic: In addition to Tsuruya, from the source material, her father also has it. Both of them lose it when they are stressed though.
** Matsuri also has the same recurring use of 'nii-pah' as her mother.
* VerbThis: [[spoiler:Kuyou delivers one to slider!Kuyou.]]
-->'''[[spoiler:Kuyou]]:''' Synchronize with that! Activating '[[FunSize chibi mode]]'!
* VillainousRescue: Fujiwara and Kuyou [[spoiler:come to save Kyon and Kanae from an enemy slider. Kuyou wipes two of the weapons and Fujiwara takes one of them back to (presumably) his original time. Kyon takes one for himself.]]
* VSign: Haruhi and Sakanaka to each other in Chapter 6 after Kyon and Haruhi return from a Student Council session.
[[#W]]
* WakeUpFighting: In a low-key take on this trope, Kyon was able to block an elbow-to-midsection wake-up strike from his sister (in her defense, [[NotAMorningPerson he had troubles to wake up by his own until that point]]) the morning after the first daily training session. This is one of the first signs ([[InMediasRes s]][[ActionPrologue o]] [[AnachronicOrder to]] [[{{Futureshadowing}} speak]]) of his [[TookALevelInBadass development as a martial artist]].
* WakeUpGoToSchoolSaveTheWorld: Played straighter than canon. Kyon even [[DiscussedTrope discoursed]] about it in Chapter 27.
-->Still, in retrospect, having to worry about both school and the abnormal side of his life -- the business of supernatural and secret organizations… The manga weren't entirely accurate when it came down to living the experiences. Strangely, it felt like less of a burden than most of his shounen heroes made it seem, and he felt he spent significantly more time actually doing school-related things than otherwise.
* WaveMotionGun: [[spoiler:''Master Spark'']] is a CombinationAttack performed by [[spoiler:Haruhi and Kuyou]] where the former creates a PureEnergy construct and feeds it with power while the latter contains and compresses it until [[ChargedAttack it has gathered enough force]] to destroy an [[spoiler:alien fortification]] which towered several ''kilometers'' high upon contact.
* WeHaveForgottenThePhlebotinum: In Chapter 47, after [[spoiler:Tsuruya and Haruhi's BedmateReveal]], Kyon was so distracted taking care of his sick sister that he left his coat behind in her room, along with pretty much everything else in it.
* WeHaveToGetTheBulletOut: PlayedWith in Chapter 20. [[spoiler:After the public shooting during the previous chapter, an injured Kyon was taken to the same hospital from the ''Disappearance''. However, as not every medic in there was under the Organization control, Koizumi asked Yuki to look for an alternative to an UnexplainedRecovery. It's implied that Yuki used her powers to turn the injury into a ludicrously easy case to treat so the doctors would decide to take the bullet out on their own.]]
* WelcomeToMyWorld: On Chapter 10:
-->'''Kyon:''' I assume that the Organization is reasonably aware of what we're doing?\\
'''Koizumi:''' I haven't a clue! I suppose you can fill me in on the way? I feel a bit clueless about this right now...\\
'''Kyon:''' Welcome to my world.
* [[WhamEpisode Wham Chapter]]: Chapter 19.
* WhamLine:
** "But then, by that logic, if ''I'' had subordinates, they could help, too?"
** "Not half as monstrous as that thing you're trying to kiss."
* WhatDidIDoLastNight: Mion in Chapter 17. [[spoiler:It was a three-way between Keiichi, Mion, and Rena.]] Rena's blush at that statement indicates that she remembers, and the others' reactions indicate that they know what happened, anyway.
* WhatHappenedToTheMouse: Early on Kanae mentions being stalked by three enemy sliders. An evil boy (Wataru), a girl with dark hair (alternate!Kuyou), and an evil duplicate of herself. While the first two appear over the course of the story her evil duplicate is never mentioned again.
* WhatTheHellHero: Kyon thinks this as he was climbing across the peaked roof of a two-story house in the dead of night with Yuki. ItMakesSenseInContext.
* WhatMeasureIsAMook: Averted with Kyon on Chapter 11, when he was worried about [[DoesNotKnowHisOwnStrength how bad he had harmed]] the {{Mooks}} he just fought.
* WhatWouldXDo: To force Nonoko to go home, Kyon asked her, "What would a defender of justice do?". It actually worked as she had to be sure her friend get home safely.
* WhoAreYou: Right after Kyon [[DynamicEntry arrives to rescue Tsuruya and her bodyguard from a dozen Yakuza]]:
-->'''Yakuza Mook:''' You've bought yourself ten seconds, and a one-way ticket to a world of hurt, kid. Who the hell do you think you are?\\
'''Kyon:''' Today, I'm a defender of justice, and that girl's guardian. Cliché though it may sound ... from this point on if you want to get to her, or him, you go through ''me''.
* TheWorldIsJustAwesome: As technical and somewhat laconic as her narration may be, the FreefallRomance scene between Yuki and Kyon in Chapter 39 carries this vibe:
-->Just then they burst through the wet fog, falling with the expanses of rain around them. Parallel to the bottom of the cloud they had passed through, the sun was visible once more. She'd already been aware of the conditions, but pressed against Kyon -- who had needed her help with something again, finally -- she thought the light changed in fascinating ways as she watched.
* WorldOfCardboardSpeech: In Chapter 25:
-->'''Mikuru(big):''' So ... in a roundabout way, you and I, together, even though I still stumble a little bit, are forging towards a brighter future. One that isn't predetermined to you, that doesn't damage the future I come from. If you understand what I said earlier ... you have the power to change me. Not my past self, so directly ... but your influence ends up helping me become the person I am. I could tell you everything; try to make it predetermined... I could say things were better or worse then they truly will be, and try to trick you into changing things for me. Once, I did - sort of - tell you about the goals of the people I work for. Instead, though, this time I'll do what Yuki-chan did. I'll tell you nothing, even if you ''would'' believe me. But I'm not trying to keep you in the dark because I want to manipulate you ... I'm telling you as little as possible because I ''believe'' in you. I have absolute confidence that if I don't limit you, you will achieve something wonderful. And maybe, just in small, selfish bits ... I might lead you towards something that I think we both would like...

* XRayVision: A variant. [[spoiler:Skynet's tactical AugmentedReality environment can display enemy movement behind visual obstacles, allowing in practice to look through typical concealment such as walls or trees.]]
[[/folder]]

[[folder: Y-Z]]
[[#Y]]
* {{Yakuza}}: [[spoiler:Tsuruya, later Kyon, and later still the entire SOS Brigade.]]
* YamatoNadeshiko: Tsuruya's mother, in the backstory.
* YearInsideHourOutside: Part of Yuki's training sessions. [[spoiler:She creates {{pocket dimension}}s and uses Kanae and the dimensional anchor to slide into them. That's where Kanae, Mikuru and Kyon practice sliding, sewing and cooking, and martial arts respectively. After a year, Mikuru uses her TPDD to send them back to the correct time and Yuki de-ages them]], thus also invoking TookALevelInBadass at the same time.
* YearsTooEarly: In Chapter 4, after Kyon's sister awakens her brother by trying to tickle him, he says her she's a hundred years too young to try that on him.
* YouAreBetterThanYouThinkYouAre: When Haruhi learns about her powers, she also learns the world is in constant threat of destruction because of closed space and how hard times has Kyon lived because of her. All of this makes her worry if she's forcing Kyon against her will if not outright breaking him, bordering a HeroicBSOD in Chapter 3. Kyon counters by mentioning her own growth and whatever trouble she's causing, it isn't intentional on her part.
* YouAreGrounded: In Chapter 7, Kyon had to work around one of these to [[spoiler:help Tsuruya with [[{{Yakuza}} Watanabe]]]]. His [[TimeTravel future self]] had to stay at home to cover his past self's tracks.
* YouAreNotAlone: [[spoiler:Michikyuu Kanae]] concludes that [[ItsNotYouItsMyEnemies staying in this world will put the SOS Brigade in risk]]. [[TrueCompanions The rest of the brigade]] tell her that she can trust them with her troubles, the same way she has helped them before.
* YouCanSayThatAgain: In Chapter 27.
-->'''Kyon:''' Lost your excuse to sneak out and grab a smoke without mom noticing?\\
'''Kyon's father:''' What she doesn't know won't hurt her.\\
'''Kyon:''' You can say that again.
* YouCanSeeMe: [[spoiler:Hanyuu and Yuki (by that time existing only in as data in order to watch over Kyon)]] are able to see and touch each other. The surprise is for the former.
** Kyon to Haruhi when he saves her from being run over by a minivan.
* YouDidEverythingYouCould: Yuki blames herself for not foreseeing events that could injure Kyon. He reminds her that she trained him, gave him most of his weapons, and that he's still alive.
* YouExclamation: Taniguchi to Kunikida in Chapter 57.
* YouHaveNoIdeaWhoYoureDealingWith: Said to Kyon in Chapter 26 the first time ([[TimeTravel chronologically speaking]]) he fights {{Yakuza}}.
-->'''Mook:''' You don't know who you're messing with.
** Of course, since he is time travelling, Kyon already knows.
* YouJustToldMe: Used by Haruhi against Kyon in the Chapter 38.
** And then Haruhi falls into one in the Chapter 50, even though she wasn't even the one being asked. Sure, Kunikida already knew, but nobody else in the room did.
* YoureNothingWithoutYourPhlebotinum: The enemy slider tends to taunt Kyon for being unable to do anything without "his dolls" ([[RealityWarper Haruhi]], [[ArtificialHuman Yuki]], etc). To be fair, he has already met some AlternateUniverse incarnations of Kyon so he's probably talking from experience (and Kyon at the beginning of the fic isn't much of a fighter either; the fic hints the current combined skills of the SOS Brigade are an unique occurrence).
* YouTalkTooMuch: Haruhi[[spoiler:'s {{Alternate Sel|f}}ves]] according to [[spoiler:Wataru]].
* YouWouldntBelieveMeIfIToldYou: In Chapter 16, after being convinced to tell his stories about the supernatural.
-->'''Kyon:''' (through ManlyTears) I...it's... It's nothing nearly that bad. I wouldn't... You may still think I'm crazy, and... Well, parts of this are secrets I don't really tell anyone else, but...
