Due to negative reception on Fanfiction.net (for his opinions, not his works) the 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 on Fanfiction.net (Warning: there will be no new updates there).Now has a dedicated forum thread.Thanks to hardworking forum goers, there is now a Visual Novelnote Technically a Kinetic Novel adaptation! Volume 1 has been released, covering everything up to the first half of chapter 5. It can be found here.A fan-made timeline can be found here and a PDF compilation is available here.There is a character sheet for more details (under construction). Please add character-specific tropes there, unless they apply to several characters or can fit in the main article fine.When adding tropes, be sure they aren't used just like in the very Troperiffic source material. Those go there.Remember to add future examples on the pages being linked to.As of 1/17/2014, the author is no longer with us.
This fic contains examples of the following tropes, in addition to those already present in the source material:
open/close all folders
Acceptable Breaks from Reality: 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.
Acoustic License: Averted in the Freefall Romance scene from Chapter 39. As it happens to skydivers and parachutists, it's normally impossible to speak to another person in such conditions. Yuki bypassed this by touching his skinsuit and transmitting her voice through bone conduction.
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 Heroic BSOD by the news of his daughter missing until he was informed Nonoko was safe.
Matsuri: O-oh, um, Kyon-nii— For, um, for extra purification— Rika: Matsu-chan, nothing about Watanagashi involves kissing. *blows a kiss to Keiichi*Chu~ Matsuri:*blushing* I— I wasn't— I mean— Mo~om! Keiichi: A direct hit! Shutaro: No! My own father! Keiichi: Arg… brain… turning to mush! Save yourselves!
Amusing Injuries: Among other things, 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.
Answer Cut: The In Medias ResPrologue 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.
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!
Arranged Marriage: Tsuruya and Kyon are set up on a omiainote and end up engaged 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.
Ascended Extra: 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 the supplemental materials at the time, are given bigger roles here. Notable examples are Yanagimotonote (canonically described as "Member of the Rhythmic Gymnastics Club. Dislike Haruhi.") and Yamanenote (canonically described as "Member of the Idol Research Club. Sniff Asakura's scent.").
Augmented Reality: It's how the SOS Brigade can perceive and interact with the chibified Asakura.
As part of her preparations, Mikuru was given an Augmented Reality system. It doesn't seem to interact very well when watching some movies.
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.
Back-to-Back Badasses: Kyon and Yuki in Chapter 44. The horde of Sumiyoshi-rengo they dismantled were less than pleased at this arrangement.
Badass Family: 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 Initial D-class Badass Driver and is apparently a descendant of the Taira clannote 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); his mother is intimidating enough that the entire Higurashi cast, possibly Mori and Haruhi herself, are very cautious of crossing her; and his little sister (when properly outfitted) can take apart the Combine's synths with a giggle. Heck, even their cat gets a badass moment or two.
Balanced Harem: Invoked. The girls in the SOS-dan take great care to share equal time with Kyon, usually at Haruhi's or Tsuruya's urging.
Kyon asks Koizumi to mail Haruhi when they are going to meet the Student Council President, so he may have just enough time to talk with Kimidori Emiri about the IDSE's goals and reasons, but not to do anything before Haruhi shows up. Works better than expected.
Tsuruya pulled off a nifty one in Chapter 29. After the surprise of her 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 Sasaki to deal with a paradigm shift such as the confirmation of the supernatural, Tsuruya made sure of keeping a "supply of Kyon-kun" at hand. All said and done, it worked remarkably well.
The Beard: After rumor goes in Kitago about Kyon being engaged, most "unclaimed" girls of the SOS Brigade get one to prevent unwanted romantic attention: Haruhi and Kanae have each other, and Mikuru has Shutaro (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.
Bedmate Reveal: Happens to Kyon when he wakes up one day just to find Kanae sleeping at his side. 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. 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, 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 willinvoke this trope every time they can get away with it. They even were Genre Savvy enough to get a special program in place that teleports the girls (except for Achakura; she is invisible after all) out of Kyon's bedroom the instant someone tries to open the door, in clear defiance of a certain problematic trope.
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.
Big Damn Heroes: In the prologue. Also happened at some other point, we finally get to see over twenty chapters after we first learned about it.
Big "NO!"/Little "No": Both played for laughs when Mikuru wants to meet Kyon (who was busy giving Haruhi a 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."
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.
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 Stealth Pun in Heroic Antics Begin Arc, Chapter 4, which is titled: 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.
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 "Porn Stash" 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 In-Universe, she managed to don a ponytail in class. Kyon predictably approved the new hairstyle.
In Chapter 11 and thanks to 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.
Yuki checks out Kyon's wristwatch. A few chapters later, 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 removing Koizumi's limitations so that he can use his ESPer powers outside of closed space.
What about Chekhov's Coat?
Chekhov's Gunman: Shamisen, seriously. To be precise, the "paragenetic silicon-based data lifeforms", who are hosted in Shamisen's body since the events of the short story Wandering Shadow, helped Kuyou out of a difficult situation in Chapter 47.
Chunky Salsa Rule: 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.
Combat and Support: After he gothis tools, Kyon does the heavy-lifting and Achakura handles the tech. Later, Kuyou acquires her chibi-mode and takes a support role for him too, among other things, granting the team with access to her Phantom Zone where the fighting can take place without the risk of collateral damage.
Combat by Champion: 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.
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, 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 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.
Kyon: Big Damn Hero was first published during the three-years long Schedule Slip after the Dissociation of Haruhi Suzumiya and, while retconning 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 Alternate Universe Fic proper.
Continuity Cameo: It seems that Kyon and Kanae made a brief but intriguing appearance in the seventh chapter of Later, another one of Durandall's fanfics, in front of the adult version of Kyon, who reacts in a savvy and very sensibleway.
adult!Kyon: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.
Also in Chapter 18, Rika told Haruhi about the "magatama incident" from HigurashiDaybreak, or more precisely the episode of the same name from 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 "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 'that way'.
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 The Big Bad by the end of Matsuribayashi-hen, where both card games were used as part of an analogy.
Contrived Coincidence: The IDSE created tools for theoretical interactions with 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.
Cooldown Hug: This trope is used fairly often, like when Haruhi hugs Tsuruya when she blames herself for 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 (after his sister joined the battle).
Cover Innocent Eyes And Ears: In Chapter 60, Mikuru covers Kanae's eyes when Kyon and Sasaki kiss for the first time. She quickly realizes it was kind of pointless as Kanae had already kissed Kyon on her own.
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.
Yuki and 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 Pocket Dimension in Chapter 59, 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 Innocent Innuendo in Chapter 63, Sasaki was coming to terms with the idea of sleeping with Kyon remarkably quickly before Haruhi corrected herself.
Cower Power: 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 — It Makes Sense in Context), 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.
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 Kyon calls her 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 chibi-mode, manages to completely bypass Sasaki's disbelief-activated Power Nullifier by virtue of being just too cute for Sasakito 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 Augmented Reality system that the SOS Brigade uses, from then and on preventing her power from interfering with it.
Dash Attack: In an interesting combined application of his Laser Blade, Deflector Shields and 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.
Dead Man Switch: Sasaki 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.
Haruhi snorted. "Yeah, well, now you've ruined her for marriage," she warned. "What!?" "Ah, n-no, I—" 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.
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. Their practicability was greatly improved after Achakura took charge of most of their micromanagement.
In a pinch, Haruhi can use her powers to improvise a temporal force shield sturdy enough to resist direct fire from a Strider's wrap cannon.
Slider!Kuyou used some sort of green Pure Energy construct to protect Wataru from enemy fire and to slow down his fall à la Green Lantern.
Denying The Antecedent: Kyon's sister resorted to this to get herself invited to the 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—
Destination Defenestration: 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.
In Chapter 4, Haruhi complained about Death of the Hypotenuse. 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:
"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 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 War and Peacenote both of them have a word count of around 587,000 words.
Dramatic Irony: Used for comedy with the "very special hell" Running Gag. 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 Arranged Marriage with Tsuruya doesn't help. He doesn't know that all the girls agreed to share him.
Haruhi and Tsuruya are chatting about Kyon and kissing in the presence of Yuki, who was silently reading:
Tsuruya: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 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 Yuki and Kyon being in a nightly Year Inside, Hour Outside 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 he can't remember it afterwards.
Tsuruya-sama, 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 Tsuruya. By Kunikida.
Happens to Sasaki in chapter 62 when the SOS brigade prove to her that Aliens, ESPers, and Time Travelers are all real, she has Power Nullifier abilities, and that she creates spaces and bestowed powers onto people like Haruhi does. She decides that Fainting in Kyon's lap is the proper thing to do.
Dynamic Entry: One of the fictional documents advise this. In addition, Kyon used it on one of the twelve Yakuza.
Electric Slide: When Kyon wanted to get from his school to the meeting point with Future!Mikuru in Chapter 42, he performed this trope. Ryouko Asakura found it interesting but quite inferior compared to teleportation.
In Chapter 33, Yuki gets her costume, and she pulls it off quite well.
EMP: One of the 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.
Empathic Weapon: When Kyon genetically imprints his new weapon, courtesy of future Kyon, he feels a highly disconcerting awareness of the weapon.
Entertainingly Wrong: 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.
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.
Excalibur in the Rust: Kyon's Ancestral Weapon. 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 Laser Blade in its original incarnation...
Facepalm: Haruhi when she realized Kyon will get in trouble with the Student Council again by dangling Yamane out a window.
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 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 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.
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 (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 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 "Kyon-kun"back to "Nii-san"note as she did in their backstory 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-sanafter he kisses her in Chapter 57.
Five Rounds Rapid: Subverted after 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 fails to work.
Flash Mob: In Chapter 53, the entire SOS Brigade plus Sasaki, Kyouko and Nonoko staged HareHareYukai in a train station dressed as Touhou characters to the surprise and delight of many passers-by. Sasaki can't help but wonder if it might be part of a Flash Mob Coverup.
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 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 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 lombax because of his tools. Ten chapters later he instead got Achakura, a Projected Chibi/Fairy Companionnote an Augmented Reality construct to be precise whose nominal responsibility is to assist Kyon at handling the very complex Applied Phlebotinum at his disposal.
There is another one hidden in the Running Gag 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. 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.
Four Is Death: 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."
Framing the Guilty Party: 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 kidnap Sasaki and Kyon with the help of the Sumiyoshi-rengo just the day before in-story.
Freefall Romance: In Chapter 39, a hasty and very tricky exit from 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.
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 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 Sasaki's future self, who later will tell them about certain events that took/will take place in Nishinomiya during the weekend, including: another kidnapping attempt, a Car Chase and Kyon and Haruhi's involvement in these. Kyon takes the hint and decides to ask Yuki for some driving training in Retroactive Preparation for redoing the weekend.
Gadget Watches: Kyon's wristwatch contains a skinsuitnote a full-body armor that looks like black body painting when activated with the capability to selectively redistribute momentum over its surfacenote 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, which in turn contains gravity manipulators originally designed for enhancedmovement. It also doubles as a radio clock (useful for Time Travel).
Genre Savvy: Many characters already are in the source material, but Haruhi turns this Up to Eleven: 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 Blessed with Suck.
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 few things wrong and thinks he's in a shonen story with Kyon as the main character. For example, he incorrectly speculates that the New Transfer Student in Chapter 62 is Kyon's "new fiancée" and/or someone he saved and who is joining the team. He got very close though. Sasaki, who fills the bill to a T, was transferred to a different sophomore class.
Gilligan Cut: As Haruhi initiates her Memory Gambit, 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.
Girls Are Really Scared of Horror Movies: After learning in Chapter 19 that Kyon promised Miyoko to take her to see a gory movie the young girl so eagerly wanted to watch, Haruhi invites herself and Mikuru along while expecting that this trope would come into play and hoping to invoke a Security Cling out of the time traveler. It goes better than planned: Miyoko and 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.
Growling Gut: Kyon in Chapter 45, after Mikuru asks him if he's hungry.
Half Truth: Kyon tells Aida that his PDA is customnote Yuki made it from Asakura's data remnants, and says that he got Akasaka's picture because if you do it right, people just look right through younote He made himself invisible.
Happens to almost all the members of the "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 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 thank Yuki and her powers for that.
As of Chapter 48, chibi!Kuyou also takes a turn riding on Kyon's head.
Heroes Gone Fishing: Kyon goes fishing with his uncle Keiichi when he goes to visit for golden week.
The entire Fanservice Arc counts as this.
Heroes Prefer Swords: In Chapter 61, Kyon uses a sword against what can be described as a Walking Tank. Justified by three reasons: it was a Laser Blade capable of cutting through its armor, he was under the protection of personal Deflector Shields and he made a point to ask Achakura first to run electronic countermeasures to mess with his enemies targeting systems. Still very risky.
Kyon comes to close to having one when the girls finally reveal the harem plot to him.
Hero Secret Service: The SOS Brigade, including the Organization and 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!
Hesitation Equals Dishonesty: 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 Time Travel.
Kyon: Well, I have to head back in anyway, since ... I forgot my shoes. Yeah. I'll see you tomorrow, alright, Tsuruya-sempai?
Hidden Depths: 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 Relationship Upgrade with her, has nothing to do with the supernatural. He was convinced that if they ever hooked up, Haruhi would eventually get bored with 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 Retroactive Precognition that nothing would come out of it even if he did.
A minor PoV character from Chapter 51 called Oe Akito is this for Haruhi. She caught his attention since her performance as ENOZ's replacement vocalist during the last 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.
In Chapter 18, Kyon discovers his sister eavesdropping Haruhi when she's outlining her plan 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, just after Haruhi glomps Kanae and Mikuru:
Haruhi: "Making such cute noises... if he ever tries to start something, those sounds will make Kyon unable to stop!" Mikuru: "S...Suzumiya-san! Spare Kanae-chan! T...take me instead!" (Haruhi is interrupted by a far-too familiar tug on the collar of her shirt) Haruhi: "Eh? Y...you, H...how long...?" Yuki: " 'If he ever tries to start something, those sounds will make Kyon unable to stop' " Kyon: "Somehow, I wasn't really sure that I should interfere..."
Huge Guy, Tiny Girl: Tsuruya observes that Kasai and Mori appear to be this after they start dating.
Humans Through Alien Eyes: 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.
Humiliation Conga: Yamane Jun. After him being caught off-guard by Tsuruya in the idol research club room 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.
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!
Hyperspace Arsenal: Somehow, Kyon tucked his slider weapon into his shirt from Haruhi's point of view.
"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 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 itnote Although the fanfiction.net version only holds up to Chapter 29.
Mikuru's "it's forbidden" speech in Chapter 29.
Iaijutsu Practitioner: An Elite Mook from the Sumiyoshi-rengo used an iaijutsu technique against Kyon in Chapter 44. 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.
I Cannot Self-Terminate: 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 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 the schematics to a special form of his Laser Blade 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.
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 on a beach, after fighting off an inter-dimensional robot.
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!"
Tsuruya happily undresses in front of Kyon, after they slept together (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 Modesty Towel. Ever.
Thanks to her tendency to imitate others 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 adorable to the "distracting" with a tendency to the former.
Crops up on occasion. First between Kanae and Kyon, then later with 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. It's his beam saber.
Kanae slept with Kyon, and Haruhi immediately lampshades everything when she meets them.
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 slips, 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.
Innocently Insensitive: Kanae in Chapter 63. 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 (single?quadruple?) date for the four of them.
Insistent Terminology: 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".
Instant Armor: Yuki adds this function to Kyon's watch, which saves his life when he gets shot.
I Think You Broke Her: After Yuki makes modifications to Kuyou using Haruhi's (Kyon-approved) Reality Warper powers, Haruhi and Tsuruya start to ask Kuyou some questions. When Tsuruya asks her 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? Ryouko: I don't get it! It's like she suddenly got overwhelmed as soon as she tried to access a memory!
It's a Long Story: 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.
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.
It Was a Gift: 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 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.
I Was Just Joking: In Kyon and Haruhi's first meeting with Michikyuu Kanae, Kyon jokingly suggests that she's a slider who knows them from a Alternate Universes after she ran away from them. Haruhi starts chasing her before he could say the line. He was right.
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 Kyon got engaged to Tsuruya.
Yuki jumps from the ground floor, hops off the wall several times, and hangs on the roof one-handed before she slides 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.
Just Between You and Me: Haruhi tried to invoke this trope to get information out of a yakuza in Chapter 55, who not only subverts it but also 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 and Sasaki mainly wanted to keep his attention away fromHaruhi's cell phone while she called for help.
Just in Time: 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 Brought Down to Normal. 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 Power Nullifier to be in effect.
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' (...) 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."
Kill Sat: Gungnir isn't quite orbital, but the effect is the same.
Know When To Fold Them: Daimonji was the only member of the photography ring who gave up rather than resisting. He got off the lightest.
A Lady on Each Arm: A bit of a decon/recon. 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).
Lampshade Hanging: 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.
Latex Space Suit: Played with. Kyon's "skinsuit" looks like black Body Paint when activated, thus having the "form fitting" requirements down pat, but it's an Instant Armor designed to be turned on and off without any need of removing whatever other clothes he could be wearing at the moment and his coat prevent Clothing Damage as par for the course, so it's unlikely that it'll play any fanservice role whatsoever.
Leap of Faith: There is an interesting instance in Chapter 47, where Kyon tried to use his gravity manipulators to jump from ground floor to the rooftop of a building 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 physics-defying equipment unless 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.
Lesser of Two Evils: Even if Kyon hardly qualifies as "evil", that's not a clear-cut conclusion for the Sympathetic Inspector Antagonist 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 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.
Literal-Minded: 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.
Living Emotional Crutch: Defied. Once the Brigade realized how emotionally dependent Kanae was on Kyon, they made a conscious effort to make her understand she can rely on all her friends.
Locked Out of the Fight: While the whole SOS Brigade was in class when the enemy slider attacked Kitago the battle was inside Kuyou's shadow song. Koizumi can't enter those spaces by himself.
In Chapter 47, the only way Asakura Ryouko could circumvent "good-child mode" and alert the brigade of a slider attack was get 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 (way back in Chapter 14) she wouldn't bathe with Kyon again until she gets the chance to invite Haruhi over to join them (It Makes Sense in Context). Yuki, always a helper, pointed out that the specific wording of the promise didn't forbid them from showering together. They still didn't go for it, though.
Love Dodecahedron: Kyon-centered. Putting aside the already established (semi-)canon pairings of Haruhi, Mikuru and Yuki, Kanae's crush on him was obvious enough since her first appearance in the storynote (to be precise, Kanae became interested in Kyon after meeting numerous alternate versions of him), Tsuruya Haruka eventually admits to harboring similar romantic feelings for him, and as of Chapter 30, the normally unflappable Sasaki is undeniably distressed by news of his engagement to Tsuruya, although 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 School Rumble.
In Chapter 22, Iyouji is shocked to realize that Kyon dismissed being shot so easily.
The above example could be chalked up to the fact Kyon lost consciousness too quickly and 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 the shooting doesn't even cross Kyon's mind when he was voicing his grievances against Ryuugu Ryo.
Marry Them All: 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. According to Rika, the romantic situation at the end of the Higurashi series turned into a No Romantic Resolution situation for several years until Rika was physically old enough to make her move on Keiichi, but the way she tried to catch Keiichi's notice nearly destroyed her and Keiichi's relationship with Mion and the rest of their friends (and considering that this is Higurashi, it's not hard to imagine how that might've played out). Disaster was only averted at the last moment when a Marry Them All 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 True Companions 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.
(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 Kyon is shot, Mikuru responds with the same line, just before fainting.
Mission Control: Haruhi and Tsuruya for Kyon when he and Sasaki go to meet the Anti-SOS Brigade.
Mob War: 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.
Mood Whiplash: Invoked in Chapter 59. After the reveal of the difficult circumstances surrounding 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: "bonbons and ponytails"). It worked.
Moment Killer: The enemy slider in Chapter 30. He found Kanae just when she was going to kiss Kyon.
Morph Weapon: One of the slider's enemies has one. 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 Villainous Rescue. Kuyou reprograms one of the weapons for Kyon, only for Fujiwara to take it. She reprograms another one for Kyon anyway.
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 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 Flash Mob in Chapter 53, and Haruhi used her power to make her hair grow faster, although not quite unbelievably fast.
As part of her training on 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 by neutralizing the alcohol's effects with her powers.
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.
My Own Grampa: 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 and ...
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 Hair Decoration as that worn by Yasumi, the Canon character Kanae was based upon.
The Yamaguchi-gumi (the Tsuruya familyYakuza is a branch of it) were responsible for most of the relief and aid efforts after the Kobe earthquake, as Kyon commented in Chapter 8. This real life event arguably becomes a plot point in Chapter 9, as it partially explains Kyon's lack of real reluctance to join the Yamaguchi-gumi.
Nice Job Breaking It, Hero: 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 Fujiwara did a Villainous Rescue on that day, so if he had not gone back in time due to Kyon's information, Kyon would have died.
"No. Just... No" Reaction: Kyon does not want to think about the idea of being his shipped with Koizumi. Kanae does. 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.
Kyon travelled back in time to defeat 12 Yakuza single-handedly, complete with Badass Longcoat, 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 Psychotic Smirk 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."
Not a Date: 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 Haruhi and the rest of the girls explained her the plan to share Kyon, making the attempt to hide that it was a date a moot point.
Not So Different: Kyon invokes this trope by name to Wataru, as they both want to protect their own sisters.
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 hold her.
The above pales in comparison with her reaction to what happened next. Due to a misconstruction, Kyon thought Yuki wanted to break up with him. At his pained acquiescence (he honestly thought 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 very reminiscent of a particularly tear-jerking scene from The Movie where Kyon returns the Literature Club application to disappearance!Nagato.
Yuki: "Don't ... let me go..."
Not What It Looks Like: 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.
Off Screen Teleportation: Kyon seems to pull off this trope from 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. Explanation: The person sighted in Nishinomiya was in fact Kyon's future self.
Oh Crap: Kuyou's response when she accidentally creates an uncontrolled singularity in the middle of her Shadow Song.
In Chapter 22, Kyon and his father have a chat. Kyon thinks his father found out about his criminal connections and activities. His father is actually talking about the arranged marriage both families have planned.
Also, in Chapter 11, Kyon mentions that he went to Nagato's place to 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 20+ Yakuza in a Curb-Stomp Battle. Mori instead gets him other forms of protection. Individually packaged, foil-wrapped 'protection'.
One Side of the Story: The reason why Yamane hates Kyon's guts. From Yamane's PoV, the events surrounding Asakura's murder attempt against Kyon looked a lot like a Love Confession going wrong(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.
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 Japanese Honorifics 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.
Pass the Popcorn: In Chapter 60, Yuki and Kuyou chose to sit back and enjoy their tea & cookies while quietly and attentively observed how their friends convinced Kyon and Sasaki to hook up.
Perception Filter: 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 "S.E.P. field" is powerful enough for her to make out with Kyon in the middle of the street with no one but them (and potentially other Interfaces) noticing a thing.
Perfectly Arranged Marriage: Initially resisted due to risk of apocalypse, but all involved parties come around to the idea quite quickly.
Phantom Zone: Kuyou utilizes her "Shadow Song" as sandbox of sorts, where she can allow herself to use her powers to a greater extent without destroying the Earth by mistake and more importantly 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.
Phlebotinum Analogy: Achakuraexplains 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 Magical Girl.
Pimped-Out Dress: 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.
Pinky Swear: Kyon's sister promises her brother not to tell Haruhi 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 in return for helping her confront the boss of the Sumiyoshi-rengo group responsible for all the kidnapping attempts and attacks against Kyon.
The Plan: Kyon suspects Ryouko had one, after he finds out that Yamane was being controlled by Ryouko via her bloomers. Yuki thinks that Yamane was just stupid enough to accidentally corrupt the data inside, accidentally letting Ryouko control him.
Polyamory: Keiichi and Kyon's aunts. They even have the schedule in the closet. Haruhi is actively angling toward this exact setup with the other female members of the SOS-Dan.
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.
Porn Stash: Kyon deleted the one on the SOS Brigade computer. He now has a small one in his phone, courtesy of Mikuru and Tsuruya.
The one who provoked the Forceful Kiss example above took a few moments to recover from it.
Adult!Mikuru also pulls this off on Kyon.
In Chapter 28, Kyon pulls this on teen!Mikuru, with the latter also "suffering" Foot Popping.
Power Incontinence: 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. After the Memory Gambit closed space stops happening but Yuki still has to control Haruhi's power full-time.
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 Time Dilation would help to accelerate the relative production rate of the data that Yuki uses to maintain her Pocket Dimension.
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: *pointing to Yuki* Kyon got so good 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.
Power-Up Food: In Chapter 59, it's revealed that Hanyuu can still materialize herself as she did in the last arc of Higurashi, 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.
Power-Up Magnet: A rare non video game example. In Chapter 61, Kuyou in her chibi-mode flew around Kyon and collected what amounts to the power cores of defeated Striders. This is a double-aimed tactic: it precludes their enemies from reusing that energy and the resources so obtained can potentially be repurposed.
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.
Kyon's block prevents Koizumi from even detecting his presence. Not even Haruhi running her powers in safe mode can bypass it.
Psychotic Smirk: 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.
Punch Catch: Averted and discussed. 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.
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 its meaning better. He was also originally mistaken about the name of 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 Repetitive Name in order to Take a Third Option.
Romance-Inducing Smudge: In Chapter 62, 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.
Sacred First Kiss: In Chapter 30, Kanae asks Kyon to be her First Kiss. 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".
Said Bookism: The characters allow and offer a whole lot more than they say.
At the end of Chapter 9, 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 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.
Scare 'Em Straight: 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.
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, Sakanaka and Yanagimoto aren't convinced that Haruhi and Kanae are really in a Romantic Two-Girl Friendship and try to get Haruhi to explain what's really going on. Haruhi eventually reveals to them the plan for a Marry Them All arrangement between Kyon the rest of the girls in the Brigade. Both girls promise to keep it secret.
Haruhi tries to invoke this trope in Chapter 19 by having Kyon take Mikuru to see a 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 movie "Trope-tan 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.
Sempai Kohai: Kyon and Kanae. And as of Chapter 32, Suzumiya-sempai as well.
In Chapter 29, Koizumi was uncomfortably aware of Haruhi's emotional state while she and Kyon were kissing. A few chapters later, after Koizumi informed Haruhi of this, the very first thing she did was to sever her Psychic Link to him and the rest of the Organization's ESPers.
"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 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 Kyouko's turn to perceive the sensations and emotional responses from Sasaki when she and Kyon were kissing. With two interesting twists: 1) Koizumi was with Kyouko at that moment and he was able to accurately recognize what was going on thanks to psychic powers and his previous experienceon 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 Relationship Upgrade with Koizumi, Kyouko resorted to a simply and effective approach to deal with the situation: glomp her boyfriend and kiss him passionately enough to be unable to tell between her own feelings and Sasaki's.
Most of the girls in the Big Damn Harem ship each other with Kyon, but Haruhi makes a conscious effort to do this.
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. Shinobu even scored an Offscreen Moment of Awesome 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 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. 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.
Ship Sinking: 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 Better as Friends 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.
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 fiancée? Kyon: I am going to forgo speaking privileges for the rest of the day.
In Chapter 51, after Yanagimoto utters an 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.
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?"
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."
Super Cell Reception: Kyon's phone can send and receive some calls even when he's not technically on Earth. Justified: Yuki prepared two sets of 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 Shadow Song and couldn't be informed about Haruhi and Sasaki's kidnapping for most of the girls' ordeal.
Nonoko: And it's going to turn me into a magical girl? 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!
Surprise Party: Chapter 60 ends with almost all the girls in the SOS Brigade welcoming Kyon to his birthday party at Mion's house.
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 Innocent Innuendo 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, 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.
Sweat Drop: Mikuru after telling Haruhi about when Kyon accompanied her buying cloth and a sewing machine.
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 Heroic BSOD she runs a Memory Gambit on herself so she doesn't destroy the world on an accidental whim.
Word of God said that the story 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" endingsnote Matsuribayashi-hen and Miotsukushi-hen, is a combination of Matsuribayashi-hen and various elements from the other Higurashi arcs.
Talking in Your Sleep: 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.
Haruhi: Can I go [back in time] with you? Kyon (reading note): "No, she can't."
Teleport Interdiction: In Chapter 63, 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.
Sure, Kyon, name the piece of sophisticated technology capable of self-advancement and created from the data remains of Ax-Crazy Asakura Ryouko Skynet. 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.
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.
Too Dumb to Live: 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.
Too Much Information: 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.
Trespassing To Talk: A variation. Thanks to his Invisibility Cloak, Kyon in two opportunities sneaked into 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.
Kyon's optimism and interest in the supernatural was destroyed by Sasaki's incessant deconstructionism; likewise, Sasaki's automatic Deconstruction of the Power of Love 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.
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.
Unbroken Vigil: After Kyon had a bullet surgically extracted, 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.
Undead Tax Exemption: 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 she slides mentally, replacing or overwriting the local Kanae with her thus never needing to have an identity— she uses the local Kanae's. She doesn't realize it.
Un Paused: 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.
Verbal Backspace: 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. 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.
Verbal Tic: 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.
Kuyou: Synchronize with that! Activating 'chibi mode'!
Villainous Rescue: Fujiwara and Kuyou 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.
V Sign: Haruhi and Sakanaka to each other in Chapter 6 after Kyon and Haruhi return from a Student Council session.
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.
We Have to Get the Bullet Out: Played With in Chapter 20. 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 Unexplained Recovery. 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.
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.
"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."
What Did I Do Last Night?: Mion in Chapter 17. 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.
What Happened to the Mouse?: 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.
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.
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.
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...
X-Ray Vision: A variant. Skynet's tactical Augmented Reality environment can display enemy movement behind visual obstacles, allowing in practice to look through typical concealment such as walls or trees.
Yakuza: Tsuruya, later Kyon, and later still the entire SOS Brigade.
Year Inside, Hour Outside: Part of Yuki's training sessions. She creates pocket dimensions 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 Took a Level in Badass at the same time.
Years Too Early: 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.
You Are Better Than You Think You Are: 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 Heroic BSOD in Chapter 3. Kyon counters by mentioning her own growth and whatever trouble she's causing, it isn't intentional on her part.
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.
You're Nothing Without Your Phlebotinum: The enemy slider tends to taunt Kyon for being unable to do anything without "his dolls" (Haruhi, Yuki, etc). To be fair, he has already met some Alternate Universe 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).
