''The Vanishing of Nagato Yuki-chan'' (in Japanese, ''Nagato Yuki-chan no Shoushitsu'') is a SpinOff slice-of-life manga for the ''LightNovel/HaruhiSuzumiya'' series. Running from 2009 to 2016 for ten volumes, the manga is written and illustrated by Puyo, creator of the original ''Manga/HaruhiChan'' manga. In this alternate universe, Yuki Nagato is not an alien; she's a quiet, ordinary girl who is the president of North High's Literature Club alongside her best friend, Ryōko Asakura, and Kyon, whom she harbours feelings for. As such, the bashful Yuki becomes even more uncertain around Kyon, who's enjoying the idle, calm environment that the Literature Club provides. With the ever-watchful Ryōko keeping an eye on Yuki, the latter's feelings do not go unnoticed; Ryōko soon pushes the reluctant Yuki forwards in expressing these feelings towards Kyon.
However, this early peace does not last: shortly after celebrating Christmas together, Kyon and Yuki encounter none other than Haruhi Suzumiya, who'd been camped out at the park in an attempt to capture Santa Claus. Her boisterous presence and actions result in Itsuki Koizumi, Mikuru Asahina and Tsuruya joining the Literature club. Kyon and Yuki are suddenly thrown into adventures and mysteries that gradually, but surely, closes the distance between the two. As they spend more time together, hints of a LoveTriangle begin to materialise, as well. An AnimatedAdaptation produced by Satelight was aired as part of the Spring2015Anime season, and an OVA also aired during October 2015.
----
!!''The Vanishing of Nagato Yuki-chan'' provides examples of:
* [[AbsurdlyPowerfulStudentCouncil Absurdly Powerful Class Representative]]: Ryōko exercises her powers as class representative in an effort to accommodate for a Christmas party in their clubroom at Yuki's request, although there are limits to what she can do (for instance, Ryōko can't alter the minimum number of members a club can have).
* AdaptationalHeroism:
** As Yuki's best friend, Ryōko resembles a doting parent, displaying none of the psychotic tendencies seen in the original series.
** While retaining a mildly manipulative attitude and blasé outlook towards rules, Haruhi is less selfish and abrasive.
* AdaptationalPersonalityChange:
** Haruhi is very excitable and ever-ready for pursuit of the mysterious. Her JerkAss mannerisms are toned down, and so, while retaining her independent GenkiGirl and CloudCuckooLander character, she develops a [[BigBrotherMentor Big Sister Mentor]] / CoolBigSis dynamic with Yuki. In some instances, Haruhi even serves as the StraightMan to Ryōko's antics. [[spoiler:Sasaki]] says that Haruhi comes off as completely different to her classmates at Koyouen, seeming like a model student that everyone looks up to, although she does point out that the way Haruhi seems at North High is in all likelihood her true self.
** Ryōko's CuteAndPsycho traits are gone; she acts as a big-sister figure to Yuki, periodically advising her on how to get along with Kyon, and generally concerns herself with being a ProperLady to keep the others in check.
** Tsuruya is friends with Ryōko, and Mikuru is a more independent individual, no longer being required to follow orders from any higher-ups.
** Koizumi's AmbiguouslyGay tendencies are less apparent in the manga, because he's [[spoiler:in love with Haruhi]]. Within the anime, some of the AmbiguouslyGay elements resurface; during the group's visit to a hot springs, Kyon finds himself uncomfortably close to Koizumi on two separate occasions while in the men's bath.
** Kyon is much [[NiceGuy friendlier]] all-around except when dealing with Haruhi, during which some of his [[FirstPersonSmartass old sarcasm reappears]] in response to her remarks.
* ArtEvolution: The artwork becomes more natural as the chapters progress, and in earlier chapters, it was quite difficult to differentiate between Ryōko and Tsuruya, particularly in black-and-white (here is a comparison between the [[http://www.mangareader.net/985-38763-4/nagato-yuki-chan-no-shoushitsu/chapter-1.html first chapter]] and [[http://www.mangareader.net/985-57379-18/nagato-yuki-chan-no-shoushitsu/chapter-12.html twelfth chapter]]).
* AscendedExtra: Taniguchi and Kunikida have a much greater presence in the anime than the manga. (In fact, in the manga chapters covered by the anime, Taniguchi appears in a whopping one panel and Kunikida doesn't appear at all. They do appear regularly in a later arc of the manga though.)
* BeachEpisode: Chapter thirty-six (episode fifteen in the anime) follows the Literature Club's visit to Tsuruya's beach house.
* BecauseYouWereNiceToMe:
** Kyon and Yuki first meet when she was too timid to ask for assistance in registering for a library card. He ends up helping her to get one so she could borrow a book.
** Koizumi sticks around Haruhi because when he was the NewTransferStudent, he was ostracised by his classmates. However, Haruhi approached him and treated him differently than everyone else. and so, while he knows that [[spoiler:Haruhi doesn't seem romantically interested in him, he's definitely in love with her]].
* BelligerentSexualTension: Haruhi and Kyon detect hostility from the other from the moment that they exchange names.
* BewareTheNiceOnes: While Ryōko [[CuteAndPsycho lacks her psychotic tendencies]], she still emanates a frightening aura whenever she finds Kyon and Yuki procrastinating or idling.
* BigEater: Yuki's fond of snacks and can eat more than her stature suggests.
* BlankWhiteEyes: These are visible on Ryōko after she changes her mind about tutoring Kyon when he tries to ask Yuki for some help instead, all the while attempting to coerce him into allowing her to tutor him instead of Yuki.
* BlindWithoutEm: Yuki appears to be entirely blind without her glasses. Barely able to coherently walk to a nearby store and back, she can't recognise Haruhi's face when she finally sees her without her glasses.
* BluntYes: When Haruhi and Ryōko are discussing Ryōko's worries about Yuki and Kyon's relationship, Haruhi replies that their friendship is strong enough to handle it.
-->'''Ryōko''': The more the distance between Nagato-san and Kyon-kun closes, the more it feels like they're moving further from me. And it's just... I hate it. It's lonely. I know, I know. I'm not protecting anyone. It's pure jealousy.
-->'''Haruhi''':''(places a hand on Ryōko's shoulder)'' Ryōko... ''(with a smile)'' Yeah, that's really dumb!
* BookEnds: In volume one, Ryōko wakes a sleeping Yuki by tugging on her hair and asking "Are you quite awake, Your Highness?". In the final volume, Ryōko repeats the action and question when she finds Yuki sleeping [[spoiler: during a visit to Japan on a vacation]].
* {{Bookworm}}: Despite being fond of games, Yuki also enjoys reading. [[spoiler:After the accident, the alternate Yuki prefers books over video games]].
* BoyfriendBluff: [[spoiler:Sasaki]] asks Kyon to pose as her boyfriend, in order to ward off potential suitors. Kyon, [[spoiler:having heard the other Yuki's confession, declines, saying after something like that, he doesn't want to go out with Sasaki, even as a lie]].
* ButtMonkey: Haruhi's machinations leave Kyon on the receiving end even in this universe; while singing some karaoke at the hot springs resort, they stick around for Mikuru's song. But when it's Kyon's turn, he decides to go all-out on it. Unfortunately, Haruhi gets bored before he even starts, so she leaves. The others following her, leaving Kyon to sing by himself.
* CannotSpitItOut: This holds true for both Yuki and Kyon. Initially, Yuki's only able to thank Kyon for helping her obtain a library card, while Kyon finds conversation with Yuki awkward [[spoiler:following her vanished alter-ego's love confession. Eventually, he replies in kind under the din of a fireworks show]]. As of volume nine, [[spoiler: this trend comes to an end, as Kyon and Yuki confess their love to each other in front of the Christmas tree at Tsuruya's house]].
* CharacterDevelopment:
** Yuki gets better at interacting with Kyon, slowly getting closer to him.
** Kyon loses some of his ObliviousToLove issues, [[spoiler:especially with the alternate Yuki]].
** Haruhi's {{Jerkass}} characteristics dramatically decreases over the series.
** Ryōko reins in some of her parental tendencies, dramatically chastising herself at times for hovering over Yuki. By the final volume, she's fully supportive of Kyon and Yuki's relationship, deciding to [[spoiler: study abroad in Canada to be closer to her parents]].
* CharlesAtlasSuperpower: Similar to her character in the other spinoff, Manga/HaruhiChan, Tsuruya is in exceptional shape. She declares a what would be considered a physically-taxing hike to be super-easy, hints that she and her family wrestle bears on vacation, and can even bodily throw someone a surprising distance.
* ChickMagnet: All of the girls appear to exhibit some degree of interest in Kyon.
* ChildhoodFriends: Ryōko and Yuki have known one another since childhood, having met when their parents introduced them to one another
* ChristmasEpisode: The first six chapters detail preparations for and partaking in a Christmas party in their clubroom.
* CliffHanger: The end of volume three leaves the outcome of Yuki's [[spoiler:near-accident]] unknown.
* ClingyJealousGirl: Yuki represents a mild case, becoming distraught whenever she feels that Kyon is becoming closer to another girl. This is especially noticeable when she she sees Haruhi giving what turns out to be nothing more than obligation chocolate, although she seems to take it well when Haruhi says she "doesn't dislike" Kyon. However, Yuki [[spoiler: takes it somewhat harder when Kyon reunites with Sasaki, whom he's known for a long time]], but Mikuru reassures her that it's natural to feel that way, later giving her advice on how to "recapture" him.
* ClubStub: Yuki's literature club is on the verge of being shut down from a lack of members; Yuki resolves to attain the sufficient numbers to continue the club's activities after speaking with Ryōko.
* ComplimentBackfire: Haruhi can't bear for Yuki to thank her, after Yuki is roped into Haruhi's scheme to capture Santa Claus.
* CrushBlush: [[spoiler:Kyon admitting to himself that he has this marks his official LoveEpiphany for Yuki.]]
* CryCute: Ryōko bursts into tears when faced with a mathematics problem she cannot solve; her class had not covered the topic yet, whereas Haruhi's school had.
* CuteClumsyGirl: [[http://www.mangareader.net/985-38763-6/nagato-yuki-chan-no-shoushitsu/chapter-1.html Yuki]] exhibits these traits in both the manga and anime:
** In the anime's opening sequence, Yuki trips shortly after running in during the title's appearance before picking herself up again.
** Tsuruya claims Mikuru demonstrates these attributes, but Mikuru protests it only happens occasionally.
* DareToBeBadass: Upon learning that the Literature Club faces closure, Ryōko delivers a passionate lecture to Yuki, asking if she's willing to do what it takes to protect the club. Despite her worries about coming across as being too harsh, Yuki gains the courage to find more members.
* DatePeepers: The ninth episode offers two instances:
** After Yuki loses in old maid, she's asked to buy drinks and snacks as a penalty. Kyon decides to escort her, provided that it's dark outside. Ryōko, Haruhi, and Koizumi end up tailing the two. They watch as Kyon and Yuki seemingly embrace for a kiss, causing Ryōko to let out a BigNo. This is [[spoiler:subverted, as it turns out to have been a very long ImagineSpot she was having]].
** However, the trope is played straight moments later. Tsuruya originally intended to bring everyone up a hidden trail to a quiet spot for stargazing, but upon seeing Ryōko and Haruhi sleeping, she suggests that Kyon and Yuki go together. Both [[spoiler: Haruhi and Ryōko wind up awakening and promptly tail the couple, though Haruhi claims she just wants to go stargazing.]]
* DaydreamSurprise: It initially appears that Yuki lost the card game and has to go shopping, with Kyon accompanying her. However, it turns out to be Ryōko's daydream, and in reality, Ryōko ends up losing.
* DeadpanSnarker: Although Kyon is a StraightMan in the series' beginning, his interactions with Haruhi gradually brings out this side of him as time progresses.
* DeathGlare: Ryōko's {{Yandere}} KnifeNut disposition are absent, but she is nonetheless quite capable of frightening Yuki and Kyon. On several instances, she's able to do so with her eyes closed, in conjunction with the [[http://www.mangareader.net/985-39482-9/nagato-yuki-chan-no-shoushitsu/chapter-5.html ]in conjunction with the]] BishieSparkle.
* DespairEventHorizon: Yuki becomes melancholy after being told that the Literature Club is to be closed for on account of lacking a sufficient number of members.
* DeterioratesIntoGibberish: Despite her exceptional intellect, Yuki's explanations for how she reaches a solution are incoherent to most everyone. As such, Ryōko refuses to allow Yuki to tutor Kyon; he likely would not have understood Yuki's explanations.
* DoggedNiceGuy: Koizumi follows Haruhi everywhere and agrees to be her lackey, despite knowing that she might lose interest in him since he's no one special.
* DraggedByTheCollar: Ryōko resorts to these means to move Yuki to the clubroom after classes end for the day during the first episode.
* DynamicEntry:
** Tsuruya throws Mikuru, breasts-first, at Kyon's head.
** Haruhi pops out of a snow covered bush at the park while Yuki and Kyon are walking by, subsequently ordering Kyon to bring her somewhere warm.
** Kyon's sister does this to Kyon as punishment for not inviting her to the beach with his friends.
* EarlyBirdCameo: Taniguchi and Kunikida appear in the anime much earlier than they did in the manga.
* EmotionlessGirl: Yuki acts in this manner during chapter twenty-six to [[spoiler: conceal her dysmnesia after a near-accident. Despite lacking the knowledge of how to behave as the original Yuki did, she manages to remain low-key and eventually falls in love with Kyon]].
* EveryoneCanSeeIt: Yuki's feelings for Kyon are noticed by most everyone, save Kyon himself.
** This is a MythologyGag, bearing resemblance to the situation seen in the original series with Kyon and Haruhi.
** Similarly, everyone but Haruhi knows that [[spoiler:Koizumi is crushing on her]].
* EvolvingCredits: In the anime, the ending credits show scenes of Yuki interacting with all the major characters. During the [[spoiler: "Disappearance" arc, the characters are all cast in colored silhouettes. A second is seen Yuki observing them near the end, mirroring how the other Yuki doesn't consider these memories as her own.]]
* {{Fanservice}}:
** When Kyon joins Ryōko and Yuki for dinner during chapter two, Yuki spills food down her shirt mid-conversation and briefly struggles with Ryōko in pulling it off. They promptly stop when they realise Kyon's still there, but not before he gets half an eyeful of Yuki's navel.
** Chapter twenty-two takes place at a [[HotSpringsEpisode Hot Spring]], and chapter thirty-six is a BeachEpisode, so such moments are par the course during these chapters (and their corresponding episodes in the anime).
** In the manga, [[SplashPanel two-page spread]] of all the girls in bikinis is found a couple chapters earlier, while everyone is planning for Tanabata.
** MsFanservice: Mikuru fulfils this role more prominently in the anime.
* FastballSpecial:
** Tsuruya throws Mikuru at Kyon in chapter sixteen to give her a DynamicEntry.
** Haruhi uses Kyon as a distraction, throwing him at Tsuruya during episode three in order to "kidnap" Mikuru.
* FunbagAirbag: Kyon is subjected to this after Tsurya tosses Mikuru at him in the aforementioned DynamicEntry.
* GamerChick: Yuki retains her interest in video games; this trait was is seen in Yuki's ''Manga/HaruhiChan'' incarnation (in turn originally derived from the original Yuki's apparent enjoyment of ''Day of Sagittarius''). Conversely, the [[spoiler: alternate Yuki prefers books over games]].
* GoneHorriblyRight: Ryōko becomes uneasy in response to Kyon and Yuki's growing closeness.
* GoodMorningCrono: The first scene involves Ryōko waking a sleeping Yuki in a painful fashion.
* GotVolunteered: Kyon was made a member of the [[InstantFanClub "Mikuru Fan Club"]] without his knowledge, complete with a membership card bearing a photograph of him that was likely clandestinely taken.
* HeadbuttOfLove: [[http://www.mangareader.net/985-38764-16/nagato-yuki-chan-no-shoushitsu/chapter-2.html Yuki and Ryōko]] share a [[HeartwarmingMoment heartwarming]] moment after Ryōko promises to help realise Yuki's desire to host a Christmas party in their clubroom.
* [[SheIsNotMyGirlfriend He Is Not My Boyfriend]]:
** Yuki replies in this manner after Haruhi questions her relationship with Kyon. Unfortunately, she takes it too far, declaring him a complete stranger (to Kyon's chagrin), but later consents that they are friends.
** Haruhi bemoans having to constantly explain that Koizumi isn't her boyfriend, too. She doesn't view him anything as more than a friend, even though [[spoiler:Koizumi wishes things were different]].
* HeroicSacrifice: This is PlayedForLaughs in during chapter ten (episode three in the anime), when Haruhi "sacrifices" Koizumi and Kyon to Tsuruya in order to kidnap Mikuru. The two guys are easily "defeated", and as the Tsuruya prepares to attack Haruhi, she's stopped by a teacher who says jumping down a flight of stairs is risky. While Tsuruya is being lectured, Haruhi uses this opportunity to "steal" Mikuru away to the Literature club.
* HeterosexualLifePartners: Ryōko is Yuki's neighbor, but visits Yuki's place so often and minds over so many aspects of her life that they might as well be related. Similarly, Tsuruya and Mikuru are always seen together, with Tsuruya regarding herself as Mikuru's guardian.
** Kyon and Haruhi seem to be moving into [[PlatonicLifePartners the opposite-sex version]]. They have elements of their [[StrangeMindsThinkAlike odd connection]] from the original series, in that she opens up to him more than almost anyone else, but it seems to be more of a VitriolicBestBuds thing than romantic.
* HostileShowTakeover: Haruhi, despite not being a student of North High, quickly takes over the Literature club room, and brings in much of the antics that she does in the original series.
* HotSpringsEpisode: Episodes seven to nine in the anime (and the corresponding chapters in the manga) follow the group as they vacation at a hot springs.
* HotTeacher: Ryōko changes into a suit while tutoring Kyon, prompting him to wonder why she changed her clothes.
* HypercompetentSidekick: Ryōko is [[TheAce exceptionally skilled]] with school and housework, further finding the time to help Yuki out, and gives her encouragement when the latter is feeling down. However, her abilities have their limits: [[spoiler:she eventually gives up on a textbook problem that Haruhi goads her into trying to solve]].
* IdentityAmnesia: After her [[spoiler: near-accident during chapter twenty-five, Yuki suffers from temporary dysmnesia. While she still retains her memories, she no longer recognises them as her own and is effectively [[EmotionlessGirl a completely different person]]]]. This aspect is treated quite seriously, as her friends [[spoiler: come to terms with how to best interact with the alternate Yuki as a distinct person, who fears being regarded as just a sickness waiting to go away when for her being "cured" sounds frighteningly similar to death]].
* ImaginaryLoveTriangle: Tsuruya initially acts under the pretense that Yuki and Mikuru are rivals for Kyon's affections, despite Mikuru's protests otherwise.
* JapaneseSchoolClub: With the entire SOS brigade present, it's hard to remember that the bulk of the story takes place in the Literature Club.
* JerkWithAHeartOfGold: Despite frequently harassing Kyon for "two-timing" on Mikuru and generally enjoying extracting whatever entertainment she can from others, Tsuruya also helps with the literature club's Christmas party, shares her family's discount at a hot springs and hotel, and hosts everyone at her family's villa and private beach during summer vacation.
* JustFriends: [[spoiler:Haruhi and Koizumi are merely friends; she befriended him while he was adjusting to a new school, and eventually he, fell in love with her]].
* LastNameBasis: Despite being long-time friends, Yuki and Ryōko typically call each other by their family names.
* LighterAndSofter: As it is a SliceOfLife romantic comedy, the atmosphere in ''The Vanishing of Nagato Yuki-chan'' is much more relaxed relative to that of the original series.
* LoveConfession: While attempts are quite frequent, circumstances constantly cause [[spoiler: them to fail]]. The most poignant instance [[spoiler:occurs with Yuki's alternate personality making her feelings known. However, she does so with the knowledge that she'll [[DyingDeclarationOfLove cease to exist]] once she fully reintegrates with Yuki's original identity]].
* LoveEpiphany: As the manga progresses, both [[spoiler: Kyon begins to realise he's in love with Yuki after alternate Yuki makes her LoveConfession to Kyon]].
* LoveTriangle: Elements of a love triangle are gradually appearing.
** Haruhi supports Yuki's feelings for Kyon wholeheartedly, but there have been hints of her feelings for Kyon. Recently, it seemed chemistry was starting to bloom after Kyon pulls Haruhi out of the river, and she starts to feel something strange when Kyon pulls a John Smith-esque line. Later, Yuki walks in on Haruhi giving Kyon (obligation) chocolate during Valentines' Day, where Haruhi explains that she does feel a little bit of affection towards Kyon, stating that she "doesn't dislike him" to Yuki.
** Early on, Yuki saw Haruhi as a rival to be emulated, even in impossible things like having a ponytail.
** During the "Disappearance Arc", a love triangle materialises, involving Kyon, Yuki, and [[spoiler:Yuki's amnesiac alternate personality]]. Specifically, [[spoiler:alternate-Yuki confesses to Kyon just before Yuki's original identity reawakens, clarifying her feelings to Kyon. However, Kyon becomes conflicted as to whether he's honestly attracted to Yuki, or if she's just a stand-in for the now-faded alternate identity that managed to steal his heart during her brief life]].
* MeaningfulName: The Vanishing Of Nagato Yuki-chan [[spoiler:refers to Nagato [[NotHimself disassociating from her memories]] after nearly being hit by a car and her original, cheerful personality temporarily "vanishing"]]..
* {{Meganekko}}: Yuki is the only member of the main cast to sport a pair of her glasses.
* MistakenForGay: Mikuru's efforts to rally Yuki's courage in giving her Valentine's Day Chocolate results in some misunderstanding: she states that she'd be glad to get chocolate from Yuki if she were male, and while Yuki is aware of what she means, Tsuruya and Ryōko view it as a LoveConfession and proceed to tease Mikuru about it.
* MomentKiller: Tsuruya, Kyon's sister and Ryōko have a propensity of ruining such moments.
** In particular, Ryōko unintentionally ruins things for Yuki during the Christmas party, when she opens the window to watch the snowfall while the two are outside alone.
** Ryōko also walks in to the club room on Kyon and Yuki supposedly hugging, which happened because [[NotWhatItLooksLike Kyon took her game away to tease her a little]].
* MyBelovedSmother: Ryōko sometimes acts in this manner towards Yuki.
* MythologyGag: Numerous references to ''The Melancholy of Suzumiya Haruhi'' are made:
** In the first episode, Ryoko hands off the bags of groceries to Kyon after shopping. She remarks that her hands are cold, and the camera tilts to the same angle in the original series, right before the original Asakura ran at Kyon with a knife. Here, she simply places her hands on his face to warm them up.
** Haruhi attempts to recreate the "I am here" message to aliens on the field. Since Kyon doesn't know her, she doesn't run into him, instead asking Yuki to write said message.
** Kyon responds to Haruhi's question "Do you think kappas really exist?" with a "Dunno. Maybe they do." This mirrors the Haruhi and "John Smith" conversation.
** A flashback is shown to an alternate version of the [[spoiler:John Smith scene, although Kyon does not remember]].
** Mikuru has a star-shaped mole on her chest, and initially, only Tsuruya is aware of this.
** Like in ''Manga/HaruhiChan'', Mori is the physical education instructor.
** Yuki offers Kyon the club signup sheet in the same manner as she had in the light novels.
** Haruhi's [[TheReveal big reveal]] about her "ambitions" is featured, albeit under different circumstances.
** Haruhi dresses up in Kyon's sports uniform so as not to stand out in North High; Kyon even asks her to do her hair up in a ponytail.
** When Yuki gives a confusing explanation for a math problem, Ryōko says "It's like she's speaking some kind of alien language," referencing how Yuki's gibberish sounds exactly like the original Yuki's incantations.
** In the anime, Haruhi and Tsuruya square off with {{Animal Battle Aura}}s of [[Manga/HaruhiChan Haruhi dressed as a sheep dog and Tsuruya dressed as a swan]].
** During the Anime's version of the [[HotSpringsEpisode Literature Club field trip]], after bathing in the onsen, Haruhi declares it to be the 15,498th Ping-Pong meet, alluding to the number of repetitions quoted in the Endless Eight arc.
** Some of the wishes written for Tanabata are similar to those from 'The Melancholy of Suzumiya Haruhi''.
** Ryōko mentions that if she succumbs to stress, she just might knife Kyon.
** Chapter thirty-eight begins with [[GroundhogDayLoop a familiar scene concerning a (not-as-dramatic) declaration of not having done one's summer homework]], although this time, there is no [[MemeticMutation endless recursions of time]].
** Everyone's roles during the previous year's SchoolFestival in chapter forty-one are call-backs to the original series: Yuki was a fortune-teller, while Haruhi wrote, filmed, and directed her own movie, with Koizumi as the star. Unfortunately, she got bored and shelved it once it got into post-production. In said movie, mysterious transfer student Koizumi awakens to his PsychicPowers and uses them to fight giant monsters. Haruhi and Tsuruya also filled in for absent members of a band at North High's festival.
** Ryōko is seen humming Hare Hare Yukai while the audience gets a glimpse of her insane knife skills (while cooking).
** One of Ryōko's character songs is called "LOVE EDITION", mirroring one of her original songs, "COOL EDITION".
** Episode ten is titled "Someday in the Rain", shared with the main series' first season finale.
** Kyon's sister tries to sneak along to Kyon's trip to the beach, hiding in his duffle bag and dropkicks him like she did in ''Manga/HaruhiChan'' upon being discovered.
** Haruhi hums "Bouken Desho, Desho?" (the first opening of the main series) during the final episode.
** The final episode mirrors Endless Eight's plot, and [[spoiler: it turns out that [[TheStinger Kyon even forgot to do his summer homework]].]]
** Yuki fondly remembers Kyon helping her get a library card, as he did in the series, but in a manner that was closer to the post-credits scene from the Disappearance movie.
** Volume ten has a callout to Endless Eight when Kyon's little sister remarks "Kyon-kun, phone" in response to a text Kyon's received.
** Objects resembling Kimidori-san, [[Manga/HaruhiChan the balloon dog]], makes an appearance every so often in the background.
* NoAntagonist: With a lack of [[AliensAreBastards bastard-like aliens]], [[EldritchAbomination amoral data entities]], and [[ThePsychoRangers rival time-travelers and espers]], very little stands in the way of Yuki achieving her wish to become closer to Kyon, barring [[CanNotSpitItOut herself]].
* NormalFishInATinyPond: Ryōko is a good student at North High, but she's blown away by the math problems Koyouen students routinely solve.
* NotAMorningPerson: Ryōko regularly has to push Yuki through her morning routine to make sure the latter is ready for school on time.
* NotWhatItLooksLike:
** Yuki walks in on Haruhi giving Kyon chocolate on Valentine's Day, throws away the chocolate she had been planning to give him, and runs out of the clubroom at full speed. It turns out that [[spoiler:Haruhi's is just obligation chocolate, identical to what she then gives Koizumi]].Later, Yuki reveals that [[spoiler:she left out of consideration, and meant to present hers later - she's quite alarmed to discover she dropped hers]].
** When Kyon asks Ryōko for some tutoring, she tells him that relying on her right away is bad. He then decides to ask Yuki instead, prompting Ryōko to immediately change her mind about the tutoring. When he points out her initial refusal, she strong-arms him into agreeing. Yuki, meanwhile, has an ImagineSpot and thinks the two are secretly sharing a romantic moment, before rationalising it as NotWhatItLooksLike... just not the NotWhatItLooksLike [[WrongGenreSavvy that actually happened]].
** Ryōko walks into the club room while Kyon and Yuki are supposedly hugging. She then slowly backs out of the room and closes the door. In reality Kyon took Yuki's game away, then jokingly kept it out of reach while she attempted to get it back, bumping into him in the process. A moment later he feeds Yuki a little bit of his food to make up for teasing her, and Ryōko once again walks in on it. She hilariously tries to exit the same way she did the first time.
* ObliviousToLove: Kyon does not seem aware of Yuki's feelings due to the fact she CannotSpitItOut.
* {{Otaku}}: While not quite as passionate about games as her ''Manga/HaruhiChan'' incarnation, Yuki often plays games well into the morning hours, much to Ryōko's displeasure.
* ParentalAbandonment: Ryōko's parents are working overseas, and little is known about Yuki's parents, save when a doctor mentions their absence in passing.
* ThePiratesWhoDontDoAnything: The Literature Club's activities are largely unrelated, and save an exhibit for a culture festival involving the collection of literature, the club's members usually spend their days relaxing together.
* ProductPlacement: Kyon, his sister, and Yuki play a Monster Hunter-like game on the Nintendo 3DS. In the anime, this changes to Yuki's love of playing visual novels on her UsefulNotes/PlayStationVita.
* PublicDomainSoundtrack: 'Maurice Ravel's ''Pavane for a Dead Princess'' [[https://infinitemirai.wordpress.com/2015/12/18/pavane-for-nagato-yuki-remarks-on-the-musical-score-in-the-disappearance-of-nagato-yuki-chan/ is used as a lietmotif of sorts for Yuki]]. ''Pavane for a Dead Princess'' begins quietly, with a slow tempo; as the song continues, it transitions from pianissimo to fortissimo, without losing its slow tempo. Likewise, Yuki is content to do things at her own pace, but as she gains more confidence, her actions become bolder.
* RealPlaceBackground: In line with the original series, the anime offers a faithful depiction of the town of [[https://infinitemirai.wordpress.com/2012/04/27/nishinomiya-hyogo-home-of-the-melancholy-of-suzumiya-haruhi/ Nishinomiya]]; many landmarks are even shown in their renovated state.
* RecycledSoundtrack: Motifs from the original anime's soundtrack are used on some occasions, especially in scenes with Haruhi.
* TheReveal: Haruhi's makes her declaration about longing to meet "time travelers, aliens and espers", but the context differs compared to that of the original.
* RubberFace:
** Ryōko does this to Haruhi after finding out the latter had Yuki quickly sign a permission slip to allow her and Koizumi to enter their school for club activities despite not being students at the school.
** Haruhi in turn does this to Yuki when the latter starts getting apologetic about Haruhi doing everything for the Literature Club.
* RunningGag: Yuki's attempts to follow Ryōko's advice to get an early night before important days typically fail: unable to sleep out of excitement, she typically ends up staying up all night, playing video games. [[spoiler:Alternate Yuki gets into the same routine with books]].
* SchoolFestival: The school festival and accompanying preparations forms the focus for much of the sixth volume.
* SeriousBusiness:
** Tsuruya and Ryōko become very involved during the Mikuru vs Yuki contest to see who's more popular, reaching the point where both Mikuru and Yuki are no longer the contestants, as Tsuruya and Ryōko going head to head against one another.
** After declaring Ryōko as North High's representative against Haruhi's school and saying that an insult to their school was an insult on her, Ryōko openly challenges Haruhi to a mathematics quiz and is promptly bested.
* ShipperOnDeck: Ryōko ships Yuki with Kyon. In fact, most of the girls do (even Haruhi, who has some degree of affection for Kyon). Tsuruya attempted to ship Mikuru and Kyon for a while, but neither Mikuru nor Kyon [[JustFriends shares these sentiments]]. Kyon's sister also appears enthralled with notions of her brother and Yuki being a couple.
* ShipTease:
** Most moments deal with Kyon and Yuki.
** There's also a few instances involving Ryōko and Kyon, although it might just be that she's trying to spur Yuki into being more proactive herself.
** Hints of Haruhi and Kyon begin arising when Haruhi realizes that [[spoiler: Kyon is John Smith]], complete with mild tsundere tendencies on Haruhi's part, in the anime.
** ShipSinking: In contrast to the regular series, Kyon and Mikuru view one another as JustFriends..
* ShooOutTheClowns: For the entirety of the "Disappearance" arc, Mikuru, Tsuruya, Haruhi and Itsuki are absent. This coincides with the fact that in-universe, both schools are close to major exams and thus, the others are busy preparing for their exams.
* SingleTear: Yuki lets a single tear fall from her eye when Kyon replies to her [[spoiler:LoveConfession]] with one of his own.
* SkinshipGrope: Mikuru suffers this at Haruhi and Tsuruya's hands during their excursion to the hot springs.
* ShrinkingViolet: Yuki is one in this series, being quite shy and often unwilling to do much on her own without prodding from someone else, but as children, [[spoiler: ''Ryōko'' was quite shy and tended to depend on Yuki]].
* SpotlightStealingSquad: Despite the series not bearing her name, Haruhi's presence is very noticeable in the anime.
* TheStinger:
** At the end of episode two in the anime, Yuki forgets her meeting in the park with Haruhi to capture Santa. As she walks by with Kyon the next day, Haruhi then leaps out of the bushes and collapses, suggesting she had been there all night.
** Ryōko tells Yuki to come up with excuses to see Kyon over the summer break since they won't have club meetings as episode nine draws to a close, and shortly after, [[spoiler: Yuki is involved in a near-accident while crossing the road]].
** The final episode hits audiences with a BrickJoke several episodes in the making -- [[spoiler:Kyon forgot to do his summer homework]].
* StraightMan: Kyon is the most level-headed and usually makes snide remarks on events around him. There are cases where [[GenkiGirl Haruhi]] also fulfills this role, in response to Ryōko's ShipperOnDeck actions.
* StrangeMindsThinkAlike: Similar to the original, Kyon and Haruhi have this dynamic. Similarly, [[spoiler:Yuki confesses to Kyon at the same time that he was considering doing the exact same with her]].
* StrongerThanTheyLook: Tsuruya effortlessly ascends the hill that exhausts Kyon, Koizumi, and Yuki en route to the stargazing spot near the resort, all while carrying Mikuru piggyback for the full length of the hike.
* TeamMom: Ryōko fulfills this role for her friends, to the point where Tsuruya teases her with the idea, after Ryōko manoeuvres Kyon into some alone time with Yuki at the Christmas party. Similarly, Haruhi views Ryōko as a disapproving mother-in-law over Yuki and Kyon's relationship.
* TemptingFate: In episode nine, Koizumi and Kyon are relaxing in their room at the hot springs resort. The latter mentions that having some nice and quiet every now and then is good. The peace is disturbed almost immediately as Haruhi shows up, and says they're going to spend the whole night playing games together.
* ThemeTuneCameo: In the very first episode of the anime, Ryōko hums ''[[LightNovel/HaruhiSuzumiya Hare Hare Yukai]]'' while she cooks. In the final episode, Haruhi hums ''Bouken Desho, Desho?''.
* TheyDo: By volume eight in the manga, it's shown that [[spoiler: Yuki and Kyon confess their feelings for one another. There are no distractions and no circumstances preventing them from doing so, and subsequently, the two begin dating]].
* TimeSkip:
** The first volume of the manga skips forwards seven months after Ryōko's conversation with Yuki, leaving out details pertaining to how Kyon ended up joining the literature club until later.
** The final volume skips over much of Yuki and the others' third year, primarily showing a montage of the events of several months, eventually leading up to [[spoiler:Ryōko's depature]]
* TookALevelInKindness: Kyon and Haruhi are both noticeably nicer than their original characters, but this is most apparent with Ryōko, whose psychotic tendencies are discarded entirely, even though she can project a substantial aura of menace whenever angered.
* {{Tsundere}}: Haruhi fulfils some of the requirements for being Type B, although this is played with in that she doesn't get awkward when it's necessarily someone she's crushing on; instead, she becomes a little shy whenever someone thanks her (she had elements of this in the original, although her JerkAss personality means she's better classified as Type A).
* UncannyValleyGirl: This averted in this series for Ryōko Asakura (contrasting the main ''Haruhi'' series); she doesn't smile all the time or always have a voice of concern. She seems to have an actual normal range of emotions and they run deeper than skin-deep. From just starting the series, one can tell she's normal in this series, and she comes across very differently from how she comes across in the ''Haruhi'' series.
* UnwantedAssistance: After the above FanService happens, Yuki asks Kyon what he thought of what he saw. After worrying about how to answer, he looks over at Ryōko, who holds up a cue card that says, "It was sexy (especially your belly button)".
* UnwantedHarem: While not every girl is into Kyon, the later chapters predominantly feature a large number of girls congregating in the Literature Club room.
* ValentinesDayEpisodes: Episodes four and five in the anime, and the respective chapters in the manga, are set around Yuki's wish to gift Kyon some chocolates during Valentines' Day.
* VisualPun: The anime's opening has several of these:
** The line that can be translated as "Whether it's a sunny day, a rainy day or a snowy day" is illustrated by a shot of the school grounds on a sunny day, followed by one on a rainy day, followed by... Yuki[[note]]The Japanese word for snow also being pronounced ''yuki''[[/note]] walking down the corridor.
** The line that gives the song most of its title, ''Fure fure yo'' ("Fall, fall!" in relation to rain or snow), is accompanied by the girls swaying their hips from side to side. ''Fure'' can also be the imperative of a different verb meaning "to shake".
* VitriolicBestBuds: Ryōko and Tsuruya initially regard each other in this manner at first, but they develop a friendly rivalry as they get to know one another better. Ryōko and Haruhi later develop a similar dynamic, as do Kyon and Haruhi. In the latter case, Kyon is put-off off by Haruhi's antics, but does seem to understand her more than almost anyone else.
* WeUsedToBeFriends: Yuki and Ryōko were close friends with Kimidori in the past but began drifting apart when Kimidori joined the student council.
* WhamLine:
** From chapter twenty-six: "... I thought so. Just one more thing. [[spoiler:Who are you?]]"
** From chapter thirty-three: [[spoiler:"I... Kyon, I love you."]]
* WomanInWhite: In the "Vanishment" arc, when Yuki is being introspective, she is often wearing a white dress in her thoughts.
* YouGottaHaveBlueHair: The odd hair colours are retained despite this being a more realistic universe, and Mikuru's hair even has a colour gradient now.

''The Vanishing of Nagato Yuki-chan'' (in Japanese, ''Nagato Yuki-chan no Shoushitsu'') is a SpinOff slice-of-life manga for the ''LightNovel/HaruhiSuzumiya'' series. Running from 2009 to 2016 for ten volumes, the manga is written and illustrated by Puyo, creator of the original ''Manga/HaruhiChan'' manga. In this alternate universe, Yuki Nagato is not an alien; she's a quiet, ordinary girl who is the president of North High's Literature Club alongside her best friend, Ryōko Asakura, and Kyon, whom she harbours feelings for. As such, the bashful Yuki becomes even more uncertain around Kyon, who's enjoying the idle, calm environment that the Literature Club provides. With the ever-watchful Ryōko keeping an eye on Yuki, the latter's feelings do not go unnoticed; Ryōko soon pushes the reluctant Yuki forwards in expressing these feelings towards Kyon.
However, this early peace does not last: shortly after celebrating Christmas together, Kyon and Yuki encounter none other than Haruhi Suzumiya, who'd been camped out at the park in an attempt to capture Santa Claus. Her boisterous presence and actions result in Itsuki Koizumi, Mikuru Asahina and Tsuruya joining the Literature club. Kyon and Yuki are suddenly thrown into adventures and mysteries that gradually, but surely, closes the distance between the two. As they spend more time together, hints of a LoveTriangle begin to materialise, as well. An AnimatedAdaptation produced by Satelight was aired as part of the Spring2015Anime season, and an OVA also aired during October 2015.
----
!!''The Vanishing of Nagato Yuki-chan'' provides examples of:
* [[AbsurdlyPowerfulStudentCouncil Absurdly Powerful Class Representative]]: Ryōko exercises her powers as class representative in an effort to accommodate for a Christmas party in their clubroom at Yuki's request, although there are limits to what she can do (for instance, Ryōko can't alter the minimum number of members a club can have).
* AdaptationalHeroism:
** As Yuki's best friend, Ryōko resembles a doting parent, displaying none of the psychotic tendencies seen in the original series.
** While retaining a mildly manipulative attitude and blasé outlook towards rules, Haruhi is less selfish and abrasive.
* AdaptationalPersonalityChange:
** Haruhi is very excitable and ever-ready for pursuit of the mysterious. Her JerkAss mannerisms are toned down, and so, while retaining her independent GenkiGirl and CloudCuckooLander character, she develops a [[BigBrotherMentor Big Sister Mentor]] / CoolBigSis dynamic with Yuki. In some instances, Haruhi even serves as the StraightMan to Ryōko's antics. [[spoiler:Sasaki]] says that Haruhi comes off as completely different to her classmates at Koyouen, seeming like a model student that everyone looks up to, although she does point out that the way Haruhi seems at North High is in all likelihood her true self.
** Ryōko's CuteAndPsycho traits are gone; she acts as a big-sister figure to Yuki, periodically advising her on how to get along with Kyon, and generally concerns herself with being a ProperLady to keep the others in check.
** Tsuruya is friends with Ryōko, and Mikuru is a more independent individual, no longer being required to follow orders from any higher-ups.
** Koizumi's AmbiguouslyGay tendencies are less apparent in the manga, because he's [[spoiler:in love with Haruhi]]. Within the anime, some of the AmbiguouslyGay elements resurface; during the group's visit to a hot springs, Kyon finds himself uncomfortably close to Koizumi on two separate occasions while in the men's bath.
** Kyon is much [[NiceGuy friendlier]] all-around except when dealing with Haruhi, during which some of his [[FirstPersonSmartass old sarcasm reappears]] in response to her remarks.
* ArtEvolution: The artwork becomes more natural as the chapters progress, and in earlier chapters, it was quite difficult to differentiate between Ryōko and Tsuruya, particularly in black-and-white (here is a comparison between the [[http://www.mangareader.net/985-38763-4/nagato-yuki-chan-no-shoushitsu/chapter-1.html first chapter]] and [[http://www.mangareader.net/985-57379-18/nagato-yuki-chan-no-shoushitsu/chapter-12.html twelfth chapter]]).
* AscendedExtra: Taniguchi and Kunikida have a much greater presence in the anime than the manga. (In fact, in the manga chapters covered by the anime, Taniguchi appears in a whopping one panel and Kunikida doesn't appear at all. They do appear regularly in a later arc of the manga though.)
* BeachEpisode: Chapter thirty-six (episode fifteen in the anime) follows the Literature Club's visit to Tsuruya's beach house.
* BecauseYouWereNiceToMe:
** Kyon and Yuki first meet when she was too timid to ask for assistance in registering for a library card. He ends up helping her to get one so she could borrow a book.
** Koizumi sticks around Haruhi because when he was the NewTransferStudent, he was ostracised by his classmates. However, Haruhi approached him and treated him differently than everyone else. and so, while he knows that [[spoiler:Haruhi doesn't seem romantically interested in him, he's definitely in love with her]].
* BelligerentSexualTension: Haruhi and Kyon detect hostility from the other from the moment that they exchange names.
* BewareTheNiceOnes: While Ryōko [[CuteAndPsycho lacks her psychotic tendencies]], she still emanates a frightening aura whenever she finds Kyon and Yuki procrastinating or idling.
* BigEater: Yuki's fond of snacks and can eat more than her stature suggests.
* BlankWhiteEyes: These are visible on Ryōko after she changes her mind about tutoring Kyon when he tries to ask Yuki for some help instead, all the while attempting to coerce him into allowing her to tutor him instead of Yuki.
* BlindWithoutEm: Yuki appears to be entirely blind without her glasses. Barely able to coherently walk to a nearby store and back, she can't recognise Haruhi's face when she finally sees her without her glasses.
* BluntYes: When Haruhi and Ryōko are discussing Ryōko's worries about Yuki and Kyon's relationship, Haruhi replies that their friendship is strong enough to handle it.
-->'''Ryōko''': The more the distance between Nagato-san and Kyon-kun closes, the more it feels like they're moving further from me. And it's just... I hate it. It's lonely. I know, I know. I'm not protecting anyone. It's pure jealousy.
-->'''Haruhi''':''(places a hand on Ryōko's shoulder)'' Ryōko... ''(with a smile)'' Yeah, that's really dumb!
* BookEnds: In volume one, Ryōko wakes a sleeping Yuki by tugging on her hair and asking "Are you quite awake, Your Highness?". In the final volume, Ryōko repeats the action and question when she finds Yuki sleeping [[spoiler: during a visit to Japan on a vacation]].
* {{Bookworm}}: Despite being fond of games, Yuki also enjoys reading. [[spoiler:After the accident, the alternate Yuki prefers books over video games]].
* BoyfriendBluff: [[spoiler:Sasaki]] asks Kyon to pose as her boyfriend, in order to ward off potential suitors. Kyon, [[spoiler:having heard the other Yuki's confession, declines, saying after something like that, he doesn't want to go out with Sasaki, even as a lie]].
* ButtMonkey: Haruhi's machinations leave Kyon on the receiving end even in this universe; while singing some karaoke at the hot springs resort, they stick around for Mikuru's song. But when it's Kyon's turn, he decides to go all-out on it. Unfortunately, Haruhi gets bored before he even starts, so she leaves. The others following her, leaving Kyon to sing by himself.
* CannotSpitItOut: This holds true for both Yuki and Kyon. Initially, Yuki's only able to thank Kyon for helping her obtain a library card, while Kyon finds conversation with Yuki awkward [[spoiler:following her vanished alter-ego's love confession. Eventually, he replies in kind under the din of a fireworks show]]. As of volume nine, [[spoiler: this trend comes to an end, as Kyon and Yuki confess their love to each other in front of the Christmas tree at Tsuruya's house]].
* CharacterDevelopment:
** Yuki gets better at interacting with Kyon, slowly getting closer to him.
** Kyon loses some of his ObliviousToLove issues, [[spoiler:especially with the alternate Yuki]].
** Haruhi's {{Jerkass}} characteristics dramatically decreases over the series.
** Ryōko reins in some of her parental tendencies, dramatically chastising herself at times for hovering over Yuki. By the final volume, she's fully supportive of Kyon and Yuki's relationship, deciding to [[spoiler: study abroad in Canada to be closer to her parents]].
* CharlesAtlasSuperpower: Similar to her character in the other spinoff, Manga/HaruhiChan, Tsuruya is in exceptional shape. She declares a what would be considered a physically-taxing hike to be super-easy, hints that she and her family wrestle bears on vacation, and can even bodily throw someone a surprising distance.
* ChickMagnet: All of the girls appear to exhibit some degree of interest in Kyon.
* ChildhoodFriends: Ryōko and Yuki have known one another since childhood, having met when their parents introduced them to one another
* ChristmasEpisode: The first six chapters detail preparations for and partaking in a Christmas party in their clubroom.
* CliffHanger: The end of volume three leaves the outcome of Yuki's [[spoiler:near-accident]] unknown.
* ClingyJealousGirl: Yuki represents a mild case, becoming distraught whenever she feels that Kyon is becoming closer to another girl. This is especially noticeable when she she sees Haruhi giving what turns out to be nothing more than obligation chocolate, although she seems to take it well when Haruhi says she "doesn't dislike" Kyon. However, Yuki [[spoiler: takes it somewhat harder when Kyon reunites with Sasaki, whom he's known for a long time]], but Mikuru reassures her that it's natural to feel that way, later giving her advice on how to "recapture" him.
* ClubStub: Yuki's literature club is on the verge of being shut down from a lack of members; Yuki resolves to attain the sufficient numbers to continue the club's activities after speaking with Ryōko.
* ComplimentBackfire: Haruhi can't bear for Yuki to thank her, after Yuki is roped into Haruhi's scheme to capture Santa Claus.
* CrushBlush: [[spoiler:Kyon admitting to himself that he has this marks his official LoveEpiphany for Yuki.]]
* CryCute: Ryōko bursts into tears when faced with a mathematics problem she cannot solve; her class had not covered the topic yet, whereas Haruhi's school had.
* CuteClumsyGirl: [[http://www.mangareader.net/985-38763-6/nagato-yuki-chan-no-shoushitsu/chapter-1.html Yuki]] exhibits these traits in both the manga and anime:
** In the anime's opening sequence, Yuki trips shortly after running in during the title's appearance before picking herself up again.
** Tsuruya claims Mikuru demonstrates these attributes, but Mikuru protests it only happens occasionally.
* DareToBeBadass: Upon learning that the Literature Club faces closure, Ryōko delivers a passionate lecture to Yuki, asking if she's willing to do what it takes to protect the club. Despite her worries about coming across as being too harsh, Yuki gains the courage to find more members.
* DatePeepers: The ninth episode offers two instances:
** After Yuki loses in old maid, she's asked to buy drinks and snacks as a penalty. Kyon decides to escort her, provided that it's dark outside. Ryōko, Haruhi, and Koizumi end up tailing the two. They watch as Kyon and Yuki seemingly embrace for a kiss, causing Ryōko to let out a BigNo. This is [[spoiler:subverted, as it turns out to have been a very long ImagineSpot she was having]].
** However, the trope is played straight moments later. Tsuruya originally intended to bring everyone up a hidden trail to a quiet spot for stargazing, but upon seeing Ryōko and Haruhi sleeping, she suggests that Kyon and Yuki go together. Both [[spoiler: Haruhi and Ryōko wind up awakening and promptly tail the couple, though Haruhi claims she just wants to go stargazing.]]
* DaydreamSurprise: It initially appears that Yuki lost the card game and has to go shopping, with Kyon accompanying her. However, it turns out to be Ryōko's daydream, and in reality, Ryōko ends up losing.
* DeadpanSnarker: Although Kyon is a StraightMan in the series' beginning, his interactions with Haruhi gradually brings out this side of him as time progresses.
* DeathGlare: Ryōko's {{Yandere}} KnifeNut disposition are absent, but she is nonetheless quite capable of frightening Yuki and Kyon. On several instances, she's able to do so with her eyes closed, in conjunction with the [[http://www.mangareader.net/985-39482-9/nagato-yuki-chan-no-shoushitsu/chapter-5.html ]in conjunction with the]] BishieSparkle.
* DespairEventHorizon: Yuki becomes melancholy after being told that the Literature Club is to be closed for on account of lacking a sufficient number of members.
* DeterioratesIntoGibberish: Despite her exceptional intellect, Yuki's explanations for how she reaches a solution are incoherent to most everyone. As such, Ryōko refuses to allow Yuki to tutor Kyon; he likely would not have understood Yuki's explanations.
* DoggedNiceGuy: Koizumi follows Haruhi everywhere and agrees to be her lackey, despite knowing that she might lose interest in him since he's no one special.
* DraggedByTheCollar: Ryōko resorts to these means to move Yuki to the clubroom after classes end for the day during the first episode.
* DynamicEntry:
** Tsuruya throws Mikuru, breasts-first, at Kyon's head.
** Haruhi pops out of a snow covered bush at the park while Yuki and Kyon are walking by, subsequently ordering Kyon to bring her somewhere warm.
** Kyon's sister does this to Kyon as punishment for not inviting her to the beach with his friends.
* EarlyBirdCameo: Taniguchi and Kunikida appear in the anime much earlier than they did in the manga.
* EmotionlessGirl: Yuki acts in this manner during chapter twenty-six to [[spoiler: conceal her dysmnesia after a near-accident. Despite lacking the knowledge of how to behave as the original Yuki did, she manages to remain low-key and eventually falls in love with Kyon]].
* EveryoneCanSeeIt: Yuki's feelings for Kyon are noticed by most everyone, save Kyon himself.
** This is a MythologyGag, bearing resemblance to the situation seen in the original series with Kyon and Haruhi.
** Similarly, everyone but Haruhi knows that [[spoiler:Koizumi is crushing on her]].
* EvolvingCredits: In the anime, the ending credits show scenes of Yuki interacting with all the major characters. During the [[spoiler: "Disappearance" arc, the characters are all cast in colored silhouettes. A second is seen Yuki observing them near the end, mirroring how the other Yuki doesn't consider these memories as her own.]]
* {{Fanservice}}:
** When Kyon joins Ryōko and Yuki for dinner during chapter two, Yuki spills food down her shirt mid-conversation and briefly struggles with Ryōko in pulling it off. They promptly stop when they realise Kyon's still there, but not before he gets half an eyeful of Yuki's navel.
** Chapter twenty-two takes place at a [[HotSpringsEpisode Hot Spring]], and chapter thirty-six is a BeachEpisode, so such moments are par the course during these chapters (and their corresponding episodes in the anime).
** In the manga, [[SplashPanel two-page spread]] of all the girls in bikinis is found a couple chapters earlier, while everyone is planning for Tanabata.
** MsFanservice: Mikuru fulfils this role more prominently in the anime.
* FastballSpecial:
** Tsuruya throws Mikuru at Kyon in chapter sixteen to give her a DynamicEntry.
** Haruhi uses Kyon as a distraction, throwing him at Tsuruya during episode three in order to "kidnap" Mikuru.
* FunbagAirbag: Kyon is subjected to this after Tsurya tosses Mikuru at him in the aforementioned DynamicEntry.
* GamerChick: Yuki retains her interest in video games; this trait was is seen in Yuki's ''Manga/HaruhiChan'' incarnation (in turn originally derived from the original Yuki's apparent enjoyment of ''Day of Sagittarius''). Conversely, the [[spoiler: alternate Yuki prefers books over games]].
* GoneHorriblyRight: Ryōko becomes uneasy in response to Kyon and Yuki's growing closeness.
* GoodMorningCrono: The first scene involves Ryōko waking a sleeping Yuki in a painful fashion.
* GotVolunteered: Kyon was made a member of the [[InstantFanClub "Mikuru Fan Club"]] without his knowledge, complete with a membership card bearing a photograph of him that was likely clandestinely taken.
* HeadbuttOfLove: [[http://www.mangareader.net/985-38764-16/nagato-yuki-chan-no-shoushitsu/chapter-2.html Yuki and Ryōko]] share a [[HeartwarmingMoment heartwarming]] moment after Ryōko promises to help realise Yuki's desire to host a Christmas party in their clubroom.
* [[SheIsNotMyGirlfriend He Is Not My Boyfriend]]:
** Yuki replies in this manner after Haruhi questions her relationship with Kyon. Unfortunately, she takes it too far, declaring him a complete stranger (to Kyon's chagrin), but later consents that they are friends.
** Haruhi bemoans having to constantly explain that Koizumi isn't her boyfriend, too. She doesn't view him anything as more than a friend, even though [[spoiler:Koizumi wishes things were different]].
* HeroicSacrifice: This is PlayedForLaughs in during chapter ten (episode three in the anime), when Haruhi "sacrifices" Koizumi and Kyon to Tsuruya in order to kidnap Mikuru. The two guys are easily "defeated", and as the Tsuruya prepares to attack Haruhi, she's stopped by a teacher who says jumping down a flight of stairs is risky. While Tsuruya is being lectured, Haruhi uses this opportunity to "steal" Mikuru away to the Literature club.
* HeterosexualLifePartners: Ryōko is Yuki's neighbor, but visits Yuki's place so often and minds over so many aspects of her life that they might as well be related. Similarly, Tsuruya and Mikuru are always seen together, with Tsuruya regarding herself as Mikuru's guardian.
** Kyon and Haruhi seem to be moving into [[PlatonicLifePartners the opposite-sex version]]. They have elements of their [[StrangeMindsThinkAlike odd connection]] from the original series, in that she opens up to him more than almost anyone else, but it seems to be more of a VitriolicBestBuds thing than romantic.
* HostileShowTakeover: Haruhi, despite not being a student of North High, quickly takes over the Literature club room, and brings in much of the antics that she does in the original series.
* HotSpringsEpisode: Episodes seven to nine in the anime (and the corresponding chapters in the manga) follow the group as they vacation at a hot springs.
* HotTeacher: Ryōko changes into a suit while tutoring Kyon, prompting him to wonder why she changed her clothes.
* HypercompetentSidekick: Ryōko is [[TheAce exceptionally skilled]] with school and housework, further finding the time to help Yuki out, and gives her encouragement when the latter is feeling down. However, her abilities have their limits: [[spoiler:she eventually gives up on a textbook problem that Haruhi goads her into trying to solve]].
* IdentityAmnesia: After her [[spoiler: near-accident during chapter twenty-five, Yuki suffers from temporary dysmnesia. While she still retains her memories, she no longer recognises them as her own and is effectively [[EmotionlessGirl a completely different person]]]]. This aspect is treated quite seriously, as her friends [[spoiler: come to terms with how to best interact with the alternate Yuki as a distinct person, who fears being regarded as just a sickness waiting to go away when for her being "cured" sounds frighteningly similar to death]].
* ImaginaryLoveTriangle: Tsuruya initially acts under the pretense that Yuki and Mikuru are rivals for Kyon's affections, despite Mikuru's protests otherwise.
* JapaneseSchoolClub: With the entire SOS brigade present, it's hard to remember that the bulk of the story takes place in the Literature Club.
* JerkWithAHeartOfGold: Despite frequently harassing Kyon for "two-timing" on Mikuru and generally enjoying extracting whatever entertainment she can from others, Tsuruya also helps with the literature club's Christmas party, shares her family's discount at a hot springs and hotel, and hosts everyone at her family's villa and private beach during summer vacation.
* JustFriends: [[spoiler:Haruhi and Koizumi are merely friends; she befriended him while he was adjusting to a new school, and eventually he, fell in love with her]].
* LastNameBasis: Despite being long-time friends, Yuki and Ryōko typically call each other by their family names.
* LighterAndSofter: As it is a SliceOfLife romantic comedy, the atmosphere in ''The Vanishing of Nagato Yuki-chan'' is much more relaxed relative to that of the original series.
* LoveConfession: While attempts are quite frequent, circumstances constantly cause [[spoiler: them to fail]]. The most poignant instance [[spoiler:occurs with Yuki's alternate personality making her feelings known. However, she does so with the knowledge that she'll [[DyingDeclarationOfLove cease to exist]] once she fully reintegrates with Yuki's original identity]].
* LoveEpiphany: As the manga progresses, both [[spoiler: Kyon begins to realise he's in love with Yuki after alternate Yuki makes her LoveConfession to Kyon]].
* LoveTriangle: Elements of a love triangle are gradually appearing.
** Haruhi supports Yuki's feelings for Kyon wholeheartedly, but there have been hints of her feelings for Kyon. Recently, it seemed chemistry was starting to bloom after Kyon pulls Haruhi out of the river, and she starts to feel something strange when Kyon pulls a John Smith-esque line. Later, Yuki walks in on Haruhi giving Kyon (obligation) chocolate during Valentines' Day, where Haruhi explains that she does feel a little bit of affection towards Kyon, stating that she "doesn't dislike him" to Yuki.
** Early on, Yuki saw Haruhi as a rival to be emulated, even in impossible things like having a ponytail.
** During the "Disappearance Arc", a love triangle materialises, involving Kyon, Yuki, and [[spoiler:Yuki's amnesiac alternate personality]]. Specifically, [[spoiler:alternate-Yuki confesses to Kyon just before Yuki's original identity reawakens, clarifying her feelings to Kyon. However, Kyon becomes conflicted as to whether he's honestly attracted to Yuki, or if she's just a stand-in for the now-faded alternate identity that managed to steal his heart during her brief life]].
* MeaningfulName: The Vanishing Of Nagato Yuki-chan [[spoiler:refers to Nagato [[NotHimself disassociating from her memories]] after nearly being hit by a car and her original, cheerful personality temporarily "vanishing"]]..
* {{Meganekko}}: Yuki is the only member of the main cast to sport a pair of her glasses.
* MistakenForGay: Mikuru's efforts to rally Yuki's courage in giving her Valentine's Day Chocolate results in some misunderstanding: she states that she'd be glad to get chocolate from Yuki if she were male, and while Yuki is aware of what she means, Tsuruya and Ryōko view it as a LoveConfession and proceed to tease Mikuru about it.
* MomentKiller: Tsuruya, Kyon's sister and Ryōko have a propensity of ruining such moments.
** In particular, Ryōko unintentionally ruins things for Yuki during the Christmas party, when she opens the window to watch the snowfall while the two are outside alone.
** Ryōko also walks in to the club room on Kyon and Yuki supposedly hugging, which happened because [[NotWhatItLooksLike Kyon took her game away to tease her a little]].
* MyBelovedSmother: Ryōko sometimes acts in this manner towards Yuki.
* MythologyGag: Numerous references to ''The Melancholy of Suzumiya Haruhi'' are made:
** In the first episode, Ryoko hands off the bags of groceries to Kyon after shopping. She remarks that her hands are cold, and the camera tilts to the same angle in the original series, right before the original Asakura ran at Kyon with a knife. Here, she simply places her hands on his face to warm them up.
** Haruhi attempts to recreate the "I am here" message to aliens on the field. Since Kyon doesn't know her, she doesn't run into him, instead asking Yuki to write said message.
** Kyon responds to Haruhi's question "Do you think kappas really exist?" with a "Dunno. Maybe they do." This mirrors the Haruhi and "John Smith" conversation.
** A flashback is shown to an alternate version of the [[spoiler:John Smith scene, although Kyon does not remember]].
** Mikuru has a star-shaped mole on her chest, and initially, only Tsuruya is aware of this.
** Like in ''Manga/HaruhiChan'', Mori is the physical education instructor.
** Yuki offers Kyon the club signup sheet in the same manner as she had in the light novels.
** Haruhi's [[TheReveal big reveal]] about her "ambitions" is featured, albeit under different circumstances.
** Haruhi dresses up in Kyon's sports uniform so as not to stand out in North High; Kyon even asks her to do her hair up in a ponytail.
** When Yuki gives a confusing explanation for a math problem, Ryōko says "It's like she's speaking some kind of alien language," referencing how Yuki's gibberish sounds exactly like the original Yuki's incantations.
** In the anime, Haruhi and Tsuruya square off with {{Animal Battle Aura}}s of [[Manga/HaruhiChan Haruhi dressed as a sheep dog and Tsuruya dressed as a swan]].
** During the Anime's version of the [[HotSpringsEpisode Literature Club field trip]], after bathing in the onsen, Haruhi declares it to be the 15,498th Ping-Pong meet, alluding to the number of repetitions quoted in the Endless Eight arc.
** Some of the wishes written for Tanabata are similar to those from 'The Melancholy of Suzumiya Haruhi''.
** Ryōko mentions that if she succumbs to stress, she just might knife Kyon.
** Chapter thirty-eight begins with [[GroundhogDayLoop a familiar scene concerning a (not-as-dramatic) declaration of not having done one's summer homework]], although this time, there is no [[MemeticMutation endless recursions of time]].
** Everyone's roles during the previous year's SchoolFestival in chapter forty-one are call-backs to the original series: Yuki was a fortune-teller, while Haruhi wrote, filmed, and directed her own movie, with Koizumi as the star. Unfortunately, she got bored and shelved it once it got into post-production. In said movie, mysterious transfer student Koizumi awakens to his PsychicPowers and uses them to fight giant monsters. Haruhi and Tsuruya also filled in for absent members of a band at North High's festival.
** Ryōko is seen humming Hare Hare Yukai while the audience gets a glimpse of her insane knife skills (while cooking).
** One of Ryōko's character songs is called "LOVE EDITION", mirroring one of her original songs, "COOL EDITION".
** Episode ten is titled "Someday in the Rain", shared with the main series' first season finale.
** Kyon's sister tries to sneak along to Kyon's trip to the beach, hiding in his duffle bag and dropkicks him like she did in ''Manga/HaruhiChan'' upon being discovered.
** Haruhi hums "Bouken Desho, Desho?" (the first opening of the main series) during the final episode.
** The final episode mirrors Endless Eight's plot, and [[spoiler: it turns out that [[TheStinger Kyon even forgot to do his summer homework]].]]
** Yuki fondly remembers Kyon helping her get a library card, as he did in the series, but in a manner that was closer to the post-credits scene from the Disappearance movie.
** Volume ten has a callout to Endless Eight when Kyon's little sister remarks "Kyon-kun, phone" in response to a text Kyon's received.
** Objects resembling Kimidori-san, [[Manga/HaruhiChan the balloon dog]], makes an appearance every so often in the background.
* NoAntagonist: With a lack of [[AliensAreBastards bastard-like aliens]], [[EldritchAbomination amoral data entities]], and [[ThePsychoRangers rival time-travelers and espers]], very little stands in the way of Yuki achieving her wish to become closer to Kyon, barring [[CanNotSpitItOut herself]].
* NormalFishInATinyPond: Ryōko is a good student at North High, but she's blown away by the math problems Koyouen students routinely solve.
* NotAMorningPerson: Ryōko regularly has to push Yuki through her morning routine to make sure the latter is ready for school on time.
* NotWhatItLooksLike:
** Yuki walks in on Haruhi giving Kyon chocolate on Valentine's Day, throws away the chocolate she had been planning to give him, and runs out of the clubroom at full speed. It turns out that [[spoiler:Haruhi's is just obligation chocolate, identical to what she then gives Koizumi]].Later, Yuki reveals that [[spoiler:she left out of consideration, and meant to present hers later - she's quite alarmed to discover she dropped hers]].
** When Kyon asks Ryōko for some tutoring, she tells him that relying on her right away is bad. He then decides to ask Yuki instead, prompting Ryōko to immediately change her mind about the tutoring. When he points out her initial refusal, she strong-arms him into agreeing. Yuki, meanwhile, has an ImagineSpot and thinks the two are secretly sharing a romantic moment, before rationalising it as NotWhatItLooksLike... just not the NotWhatItLooksLike [[WrongGenreSavvy that actually happened]].
** Ryōko walks into the club room while Kyon and Yuki are supposedly hugging. She then slowly backs out of the room and closes the door. In reality Kyon took Yuki's game away, then jokingly kept it out of reach while she attempted to get it back, bumping into him in the process. A moment later he feeds Yuki a little bit of his food to make up for teasing her, and Ryōko once again walks in on it. She hilariously tries to exit the same way she did the first time.
* ObliviousToLove: Kyon does not seem aware of Yuki's feelings due to the fact she CannotSpitItOut.
* {{Otaku}}: While not quite as passionate about games as her ''Manga/HaruhiChan'' incarnation, Yuki often plays games well into the morning hours, much to Ryōko's displeasure.
* ParentalAbandonment: Ryōko's parents are working overseas, and little is known about Yuki's parents, save when a doctor mentions their absence in passing.
* ThePiratesWhoDontDoAnything: The Literature Club's activities are largely unrelated, and save an exhibit for a culture festival involving the collection of literature, the club's members usually spend their days relaxing together.
* ProductPlacement: Kyon, his sister, and Yuki play a Monster Hunter-like game on the Nintendo 3DS. In the anime, this changes to Yuki's love of playing visual novels on her UsefulNotes/PlayStationVita.
* PublicDomainSoundtrack: 'Maurice Ravel's ''Pavane for a Dead Princess'' [[https://infinitemirai.wordpress.com/2015/12/18/pavane-for-nagato-yuki-remarks-on-the-musical-score-in-the-disappearance-of-nagato-yuki-chan/ is used as a lietmotif of sorts for Yuki]]. ''Pavane for a Dead Princess'' begins quietly, with a slow tempo; as the song continues, it transitions from pianissimo to fortissimo, without losing its slow tempo. Likewise, Yuki is content to do things at her own pace, but as she gains more confidence, her actions become bolder.
* RealPlaceBackground: In line with the original series, the anime offers a faithful depiction of the town of [[https://infinitemirai.wordpress.com/2012/04/27/nishinomiya-hyogo-home-of-the-melancholy-of-suzumiya-haruhi/ Nishinomiya]]; many landmarks are even shown in their renovated state.
* RecycledSoundtrack: Motifs from the original anime's soundtrack are used on some occasions, especially in scenes with Haruhi.
* TheReveal: Haruhi's makes her declaration about longing to meet "time travelers, aliens and espers", but the context differs compared to that of the original.
* RubberFace:
** Ryōko does this to Haruhi after finding out the latter had Yuki quickly sign a permission slip to allow her and Koizumi to enter their school for club activities despite not being students at the school.
** Haruhi in turn does this to Yuki when the latter starts getting apologetic about Haruhi doing everything for the Literature Club.
* RunningGag: Yuki's attempts to follow Ryōko's advice to get an early night before important days typically fail: unable to sleep out of excitement, she typically ends up staying up all night, playing video games. [[spoiler:Alternate Yuki gets into the same routine with books]].
* SchoolFestival: The school festival and accompanying preparations forms the focus for much of the sixth volume.
* SeriousBusiness:
** Tsuruya and Ryōko become very involved during the Mikuru vs Yuki contest to see who's more popular, reaching the point where both Mikuru and Yuki are no longer the contestants, as Tsuruya and Ryōko going head to head against one another.
** After declaring Ryōko as North High's representative against Haruhi's school and saying that an insult to their school was an insult on her, Ryōko openly challenges Haruhi to a mathematics quiz and is promptly bested.
* ShipperOnDeck: Ryōko ships Yuki with Kyon. In fact, most of the girls do (even Haruhi, who has some degree of affection for Kyon). Tsuruya attempted to ship Mikuru and Kyon for a while, but neither Mikuru nor Kyon [[JustFriends shares these sentiments]]. Kyon's sister also appears enthralled with notions of her brother and Yuki being a couple.
* ShipTease:
** Most moments deal with Kyon and Yuki.
** There's also a few instances involving Ryōko and Kyon, although it might just be that she's trying to spur Yuki into being more proactive herself.
** Hints of Haruhi and Kyon begin arising when Haruhi realizes that [[spoiler: Kyon is John Smith]], complete with mild tsundere tendencies on Haruhi's part, in the anime.
** ShipSinking: In contrast to the regular series, Kyon and Mikuru view one another as JustFriends..
* ShooOutTheClowns: For the entirety of the "Disappearance" arc, Mikuru, Tsuruya, Haruhi and Itsuki are absent. This coincides with the fact that in-universe, both schools are close to major exams and thus, the others are busy preparing for their exams.
* SingleTear: Yuki lets a single tear fall from her eye when Kyon replies to her [[spoiler:LoveConfession]] with one of his own.
* SkinshipGrope: Mikuru suffers this at Haruhi and Tsuruya's hands during their excursion to the hot springs.
* ShrinkingViolet: Yuki is one in this series, being quite shy and often unwilling to do much on her own without prodding from someone else, but as children, [[spoiler: ''Ryōko'' was quite shy and tended to depend on Yuki]].
* SpotlightStealingSquad: Despite the series not bearing her name, Haruhi's presence is very noticeable in the anime.
* TheStinger:
** At the end of episode two in the anime, Yuki forgets her meeting in the park with Haruhi to capture Santa. As she walks by with Kyon the next day, Haruhi then leaps out of the bushes and collapses, suggesting she had been there all night.
** Ryōko tells Yuki to come up with excuses to see Kyon over the summer break since they won't have club meetings as episode nine draws to a close, and shortly after, [[spoiler: Yuki is involved in a near-accident while crossing the road]].
** The final episode hits audiences with a BrickJoke several episodes in the making -- [[spoiler:Kyon forgot to do his summer homework]].
* StraightMan: Kyon is the most level-headed and usually makes snide remarks on events around him. There are cases where [[GenkiGirl Haruhi]] also fulfills this role, in response to Ryōko's ShipperOnDeck actions.
* StrangeMindsThinkAlike: Similar to the original, Kyon and Haruhi have this dynamic. Similarly, [[spoiler:Yuki confesses to Kyon at the same time that he was considering doing the exact same with her]].
* StrongerThanTheyLook: Tsuruya effortlessly ascends the hill that exhausts Kyon, Koizumi, and Yuki en route to the stargazing spot near the resort, all while carrying Mikuru piggyback for the full length of the hike.
* TeamMom: Ryōko fulfills this role for her friends, to the point where Tsuruya teases her with the idea, after Ryōko manoeuvres Kyon into some alone time with Yuki at the Christmas party. Similarly, Haruhi views Ryōko as a disapproving mother-in-law over Yuki and Kyon's relationship.
* TemptingFate: In episode nine, Koizumi and Kyon are relaxing in their room at the hot springs resort. The latter mentions that having some nice and quiet every now and then is good. The peace is disturbed almost immediately as Haruhi shows up, and says they're going to spend the whole night playing games together.
* ThemeTuneCameo: In the very first episode of the anime, Ryōko hums ''[[LightNovel/HaruhiSuzumiya Hare Hare Yukai]]'' while she cooks. In the final episode, Haruhi hums ''Bouken Desho, Desho?''.
* TheyDo: By volume eight in the manga, it's shown that [[spoiler: Yuki and Kyon confess their feelings for one another. There are no distractions and no circumstances preventing them from doing so, and subsequently, the two begin dating]].
* TimeSkip:
** The first volume of the manga skips forwards seven months after Ryōko's conversation with Yuki, leaving out details pertaining to how Kyon ended up joining the literature club until later.
** The final volume skips over much of Yuki and the others' third year, primarily showing a montage of the events of several months, eventually leading up to [[spoiler:Ryōko's depature]]
* TookALevelInKindness: Kyon and Haruhi are both noticeably nicer than their original characters, but this is most apparent with Ryōko, whose psychotic tendencies are discarded entirely, even though she can project a substantial aura of menace whenever angered.
* {{Tsundere}}: Haruhi fulfils some of the requirements for being Type B, although this is played with in that she doesn't get awkward when it's necessarily someone she's crushing on; instead, she becomes a little shy whenever someone thanks her (she had elements of this in the original, although her JerkAss personality means she's better classified as Type A).
* UncannyValleyGirl: This averted in this series for Ryōko Asakura (contrasting the main ''Haruhi'' series); she doesn't smile all the time or always have a voice of concern. She seems to have an actual normal range of emotions and they run deeper than skin-deep. From just starting the series, one can tell she's normal in this series, and she comes across very differently from how she comes across in the ''Haruhi'' series.
* UnwantedAssistance: After the above FanService happens, Yuki asks Kyon what he thought of what he saw. After worrying about how to answer, he looks over at Ryōko, who holds up a cue card that says, "It was sexy (especially your belly button)".
* UnwantedHarem: While not every girl is into Kyon, the later chapters predominantly feature a large number of girls congregating in the Literature Club room.
* ValentinesDayEpisodes: Episodes four and five in the anime, and the respective chapters in the manga, are set around Yuki's wish to gift Kyon some chocolates during Valentines' Day.
* VisualPun: The anime's opening has several of these:
** The line that can be translated as "Whether it's a sunny day, a rainy day or a snowy day" is illustrated by a shot of the school grounds on a sunny day, followed by one on a rainy day, followed by... Yuki[[note]]The Japanese word for snow also being pronounced ''yuki''[[/note]] walking down the corridor.
** The line that gives the song most of its title, ''Fure fure yo'' ("Fall, fall!" in relation to rain or snow), is accompanied by the girls swaying their hips from side to side. ''Fure'' can also be the imperative of a different verb meaning "to shake".
* VitriolicBestBuds: Ryōko and Tsuruya initially regard each other in this manner at first, but they develop a friendly rivalry as they get to know one another better. Ryōko and Haruhi later develop a similar dynamic, as do Kyon and Haruhi. In the latter case, Kyon is put-off off by Haruhi's antics, but does seem to understand her more than almost anyone else.
* WeUsedToBeFriends: Yuki and Ryōko were close friends with Kimidori in the past but began drifting apart when Kimidori joined the student council.
* WhamLine:
** From chapter twenty-six: "... I thought so. Just one more thing. [[spoiler:Who are you?]]"
** From chapter thirty-three: [[spoiler:"I... Kyon, I love you."]]
* WomanInWhite: In the "Vanishment" arc, when Yuki is being introspective, she is often wearing a white dress in her thoughts.
* YouGottaHaveBlueHair: The odd hair colours are retained despite this being a more realistic universe, and Mikuru's hair even has a colour gradient now.

to:
''The Vanishing of Nagato Yuki-chan'' (in Japanese, ''Nagato Yuki-chan no Shoushitsu'') is a SpinOff slice-of-life manga for the ''LightNovel/HaruhiSuzumiya'' series. Running from 2009 to 2016 for ten volumes, the manga is written and illustrated by Puyo, creator of the original ''Manga/HaruhiChan'' manga. In this alternate universe, Yuki Nagato is not an alien; she's a quiet, ordinary girl who is the president of North High's Literature Club alongside her best friend, Ryōko Asakura, and Kyon, whom she harbours feelings for. As such, the bashful Yuki becomes even more uncertain around Kyon, who's enjoying the idle, calm environment that the Literature Club provides. With the ever-watchful Ryōko keeping an eye on Yuki, the latter's feelings do not go unnoticed; Ryōko soon pushes the reluctant Yuki forwards in expressing these feelings towards Kyon.
However, this early peace does not last: shortly after celebrating Christmas together, Kyon and Yuki encounter none other than Haruhi Suzumiya, who'd been camped out at the park in an attempt to capture Santa Claus. Her boisterous presence and actions result in Itsuki Koizumi, Mikuru Asahina and Tsuruya joining the Literature club. Kyon and Yuki are suddenly thrown into adventures and mysteries that gradually, but surely, closes the distance between the two. As they spend more time together, hints of a LoveTriangle begin to materialise, as well. An AnimatedAdaptation produced by Satelight was aired as part of the Spring2015Anime season, and an OVA also aired during October 2015.
----
!!''The Vanishing of Nagato Yuki-chan'' provides examples of:
* [[AbsurdlyPowerfulStudentCouncil Absurdly Powerful Class Representative]]: Ryōko exercises her powers as class representative in an effort to accommodate for a Christmas party in their clubroom at Yuki's request, although there are limits to what she can do (for instance, Ryōko can't alter the minimum number of members a club can have).
* AdaptationalHeroism:
** As Yuki's best friend, Ryōko resembles a doting parent, displaying none of the psychotic tendencies seen in the original series.
** While retaining a mildly manipulative attitude and blasé outlook towards rules, Haruhi is less selfish and abrasive.
* AdaptationalPersonalityChange:
** Haruhi is very excitable and ever-ready for pursuit of the mysterious. Her JerkAss mannerisms are toned down, and so, while retaining her independent GenkiGirl and CloudCuckooLander character, she develops a [[BigBrotherMentor Big Sister Mentor]] / CoolBigSis dynamic with Yuki. In some instances, Haruhi even serves as the StraightMan to Ryōko's antics. [[spoiler:Sasaki]] says that Haruhi comes off as completely different to her classmates at Koyouen, seeming like a model student that everyone looks up to, although she does point out that the way Haruhi seems at North High is in all likelihood her true self.
** Ryōko's CuteAndPsycho traits are gone; she acts as a big-sister figure to Yuki, periodically advising her on how to get along with Kyon, and generally concerns herself with being a ProperLady to keep the others in check.
** Tsuruya is friends with Ryōko, and Mikuru is a more independent individual, no longer being required to follow orders from any higher-ups.
** Koizumi's AmbiguouslyGay tendencies are less apparent in the manga, because he's [[spoiler:in love with Haruhi]]. Within the anime, some of the AmbiguouslyGay elements resurface; during the group's visit to a hot springs, Kyon finds himself uncomfortably close to Koizumi on two separate occasions while in the men's bath.
** Kyon is much [[NiceGuy friendlier]] all-around except when dealing with Haruhi, during which some of his [[FirstPersonSmartass old sarcasm reappears]] in response to her remarks.
* ArtEvolution: The artwork becomes more natural as the chapters progress, and in earlier chapters, it was quite difficult to differentiate between Ryōko and Tsuruya, particularly in black-and-white (here is a comparison between the [[http://www.mangareader.net/985-38763-4/nagato-yuki-chan-no-shoushitsu/chapter-1.html first chapter]] and [[http://www.mangareader.net/985-57379-18/nagato-yuki-chan-no-shoushitsu/chapter-12.html twelfth chapter]]).
* AscendedExtra: Taniguchi and Kunikida have a much greater presence in the anime than the manga. (In fact, in the manga chapters covered by the anime, Taniguchi appears in a whopping one panel and Kunikida doesn't appear at all. They do appear regularly in a later arc of the manga though.)
* BeachEpisode: Chapter thirty-six (episode fifteen in the anime) follows the Literature Club's visit to Tsuruya's beach house.
* BecauseYouWereNiceToMe:
** Kyon and Yuki first meet when she was too timid to ask for assistance in registering for a library card. He ends up helping her to get one so she could borrow a book.
** Koizumi sticks around Haruhi because when he was the NewTransferStudent, he was ostracised by his classmates. However, Haruhi approached him and treated him differently than everyone else. and so, while he knows that [[spoiler:Haruhi doesn't seem romantically interested in him, he's definitely in love with her]].
* BelligerentSexualTension: Haruhi and Kyon detect hostility from the other from the moment that they exchange names.
* BewareTheNiceOnes: While Ryōko [[CuteAndPsycho lacks her psychotic tendencies]], she still emanates a frightening aura whenever she finds Kyon and Yuki procrastinating or idling.
* BigEater: Yuki's fond of snacks and can eat more than her stature suggests.
* BlankWhiteEyes: These are visible on Ryōko after she changes her mind about tutoring Kyon when he tries to ask Yuki for some help instead, all the while attempting to coerce him into allowing her to tutor him instead of Yuki.
* BlindWithoutEm: Yuki appears to be entirely blind without her glasses. Barely able to coherently walk to a nearby store and back, she can't recognise Haruhi's face when she finally sees her without her glasses.
* BluntYes: When Haruhi and Ryōko are discussing Ryōko's worries about Yuki and Kyon's relationship, Haruhi replies that their friendship is strong enough to handle it.
-->'''Ryōko''': The more the distance between Nagato-san and Kyon-kun closes, the more it feels like they're moving further from me. And it's just... I hate it. It's lonely. I know, I know. I'm not protecting anyone. It's pure jealousy.
-->'''Haruhi''':''(places a hand on Ryōko's shoulder)'' Ryōko... ''(with a smile)'' Yeah, that's really dumb!
* BookEnds: In volume one, Ryōko wakes a sleeping Yuki by tugging on her hair and asking "Are you quite awake, Your Highness?". In the final volume, Ryōko repeats the action and question when she finds Yuki sleeping [[spoiler: during a visit to Japan on a vacation]].
* {{Bookworm}}: Despite being fond of games, Yuki also enjoys reading. [[spoiler:After the accident, the alternate Yuki prefers books over video games]].
* BoyfriendBluff: [[spoiler:Sasaki]] asks Kyon to pose as her boyfriend, in order to ward off potential suitors. Kyon, [[spoiler:having heard the other Yuki's confession, declines, saying after something like that, he doesn't want to go out with Sasaki, even as a lie]].
* ButtMonkey: Haruhi's machinations leave Kyon on the receiving end even in this universe; while singing some karaoke at the hot springs resort, they stick around for Mikuru's song. But when it's Kyon's turn, he decides to go all-out on it. Unfortunately, Haruhi gets bored before he even starts, so she leaves. The others following her, leaving Kyon to sing by himself.
* CannotSpitItOut: This holds true for both Yuki and Kyon. Initially, Yuki's only able to thank Kyon for helping her obtain a library card, while Kyon finds conversation with Yuki awkward [[spoiler:following her vanished alter-ego's love confession. Eventually, he replies in kind under the din of a fireworks show]]. As of volume nine, [[spoiler: this trend comes to an end, as Kyon and Yuki confess their love to each other in front of the Christmas tree at Tsuruya's house]].
* CharacterDevelopment:
** Yuki gets better at interacting with Kyon, slowly getting closer to him.
** Kyon loses some of his ObliviousToLove issues, [[spoiler:especially with the alternate Yuki]].
** Haruhi's {{Jerkass}} characteristics dramatically decreases over the series.
** Ryōko reins in some of her parental tendencies, dramatically chastising herself at times for hovering over Yuki. By the final volume, she's fully supportive of Kyon and Yuki's relationship, deciding to [[spoiler: study abroad in Canada to be closer to her parents]].
* CharlesAtlasSuperpower: Similar to her character in the other spinoff, Manga/HaruhiChan, Tsuruya is in exceptional shape. She declares a what would be considered a physically-taxing hike to be super-easy, hints that she and her family wrestle bears on vacation, and can even bodily throw someone a surprising distance.
* ChickMagnet: All of the girls appear to exhibit some degree of interest in Kyon.
* ChildhoodFriends: Ryōko and Yuki have known one another since childhood, having met when their parents introduced them to one another
* ChristmasEpisode: The first six chapters detail preparations for and partaking in a Christmas party in their clubroom.
* CliffHanger: The end of volume three leaves the outcome of Yuki's [[spoiler:near-accident]] unknown.
* ClingyJealousGirl: Yuki represents a mild case, becoming distraught whenever she feels that Kyon is becoming closer to another girl. This is especially noticeable when she she sees Haruhi giving what turns out to be nothing more than obligation chocolate, although she seems to take it well when Haruhi says she "doesn't dislike" Kyon. However, Yuki [[spoiler: takes it somewhat harder when Kyon reunites with Sasaki, whom he's known for a long time]], but Mikuru reassures her that it's natural to feel that way, later giving her advice on how to "recapture" him.
* ClubStub: Yuki's literature club is on the verge of being shut down from a lack of members; Yuki resolves to attain the sufficient numbers to continue the club's activities after speaking with Ryōko.
* ComplimentBackfire: Haruhi can't bear for Yuki to thank her, after Yuki is roped into Haruhi's scheme to capture Santa Claus.
* CrushBlush: [[spoiler:Kyon admitting to himself that he has this marks his official LoveEpiphany for Yuki.]]
* CryCute: Ryōko bursts into tears when faced with a mathematics problem she cannot solve; her class had not covered the topic yet, whereas Haruhi's school had.
* CuteClumsyGirl: [[http://www.mangareader.net/985-38763-6/nagato-yuki-chan-no-shoushitsu/chapter-1.html Yuki]] exhibits these traits in both the manga and anime:
** In the anime's opening sequence, Yuki trips shortly after running in during the title's appearance before picking herself up again.
** Tsuruya claims Mikuru demonstrates these attributes, but Mikuru protests it only happens occasionally.
* DareToBeBadass: Upon learning that the Literature Club faces closure, Ryōko delivers a passionate lecture to Yuki, asking if she's willing to do what it takes to protect the club. Despite her worries about coming across as being too harsh, Yuki gains the courage to find more members.
* DatePeepers: The ninth episode offers two instances:
** After Yuki loses in old maid, she's asked to buy drinks and snacks as a penalty. Kyon decides to escort her, provided that it's dark outside. Ryōko, Haruhi, and Koizumi end up tailing the two. They watch as Kyon and Yuki seemingly embrace for a kiss, causing Ryōko to let out a BigNo. This is [[spoiler:subverted, as it turns out to have been a very long ImagineSpot she was having]].
** However, the trope is played straight moments later. Tsuruya originally intended to bring everyone up a hidden trail to a quiet spot for stargazing, but upon seeing Ryōko and Haruhi sleeping, she suggests that Kyon and Yuki go together. Both [[spoiler: Haruhi and Ryōko wind up awakening and promptly tail the couple, though Haruhi claims she just wants to go stargazing.]]
* DaydreamSurprise: It initially appears that Yuki lost the card game and has to go shopping, with Kyon accompanying her. However, it turns out to be Ryōko's daydream, and in reality, Ryōko ends up losing.
* DeadpanSnarker: Although Kyon is a StraightMan in the series' beginning, his interactions with Haruhi gradually brings out this side of him as time progresses.
* DeathGlare: Ryōko's {{Yandere}} KnifeNut disposition are absent, but she is nonetheless quite capable of frightening Yuki and Kyon. On several instances, she's able to do so with her eyes closed, in conjunction with the [[http://www.mangareader.net/985-39482-9/nagato-yuki-chan-no-shoushitsu/chapter-5.html ]in conjunction with the]] BishieSparkle.
* DespairEventHorizon: Yuki becomes melancholy after being told that the Literature Club is to be closed for on account of lacking a sufficient number of members.
* DeterioratesIntoGibberish: Despite her exceptional intellect, Yuki's explanations for how she reaches a solution are incoherent to most everyone. As such, Ryōko refuses to allow Yuki to tutor Kyon; he likely would not have understood Yuki's explanations.
* DoggedNiceGuy: Koizumi follows Haruhi everywhere and agrees to be her lackey, despite knowing that she might lose interest in him since he's no one special.
* DraggedByTheCollar: Ryōko resorts to these means to move Yuki to the clubroom after classes end for the day during the first episode.
* DynamicEntry:
** Tsuruya throws Mikuru, breasts-first, at Kyon's head.
** Haruhi pops out of a snow covered bush at the park while Yuki and Kyon are walking by, subsequently ordering Kyon to bring her somewhere warm.
** Kyon's sister does this to Kyon as punishment for not inviting her to the beach with his friends.
* EarlyBirdCameo: Taniguchi and Kunikida appear in the anime much earlier than they did in the manga.
* EmotionlessGirl: Yuki acts in this manner during chapter twenty-six to [[spoiler: conceal her dysmnesia after a near-accident. Despite lacking the knowledge of how to behave as the original Yuki did, she manages to remain low-key and eventually falls in love with Kyon]].
* EveryoneCanSeeIt: Yuki's feelings for Kyon are noticed by most everyone, save Kyon himself.
** This is a MythologyGag, bearing resemblance to the situation seen in the original series with Kyon and Haruhi.
** Similarly, everyone but Haruhi knows that [[spoiler:Koizumi is crushing on her]].
* EvolvingCredits: In the anime, the ending credits show scenes of Yuki interacting with all the major characters. During the [[spoiler: "Disappearance" arc, the characters are all cast in colored silhouettes. A second is seen Yuki observing them near the end, mirroring how the other Yuki doesn't consider these memories as her own.]]
* {{Fanservice}}:
** When Kyon joins Ryōko and Yuki for dinner during chapter two, Yuki spills food down her shirt mid-conversation and briefly struggles with Ryōko in pulling it off. They promptly stop when they realise Kyon's still there, but not before he gets half an eyeful of Yuki's navel.
** Chapter twenty-two takes place at a [[HotSpringsEpisode Hot Spring]], and chapter thirty-six is a BeachEpisode, so such moments are par the course during these chapters (and their corresponding episodes in the anime).
** In the manga, [[SplashPanel two-page spread]] of all the girls in bikinis is found a couple chapters earlier, while everyone is planning for Tanabata.
** MsFanservice: Mikuru fulfils this role more prominently in the anime.
* FastballSpecial:
** Tsuruya throws Mikuru at Kyon in chapter sixteen to give her a DynamicEntry.
** Haruhi uses Kyon as a distraction, throwing him at Tsuruya during episode three in order to "kidnap" Mikuru.
* FunbagAirbag: Kyon is subjected to this after Tsurya tosses Mikuru at him in the aforementioned DynamicEntry.
* GamerChick: Yuki retains her interest in video games; this trait was is seen in Yuki's ''Manga/HaruhiChan'' incarnation (in turn originally derived from the original Yuki's apparent enjoyment of ''Day of Sagittarius''). Conversely, the [[spoiler: alternate Yuki prefers books over games]].
* GoneHorriblyRight: Ryōko becomes uneasy in response to Kyon and Yuki's growing closeness.
* GoodMorningCrono: The first scene involves Ryōko waking a sleeping Yuki in a painful fashion.
* GotVolunteered: Kyon was made a member of the [[InstantFanClub "Mikuru Fan Club"]] without his knowledge, complete with a membership card bearing a photograph of him that was likely clandestinely taken.
* HeadbuttOfLove: [[http://www.mangareader.net/985-38764-16/nagato-yuki-chan-no-shoushitsu/chapter-2.html Yuki and Ryōko]] share a [[HeartwarmingMoment heartwarming]] moment after Ryōko promises to help realise Yuki's desire to host a Christmas party in their clubroom.
* [[SheIsNotMyGirlfriend He Is Not My Boyfriend]]:
** Yuki replies in this manner after Haruhi questions her relationship with Kyon. Unfortunately, she takes it too far, declaring him a complete stranger (to Kyon's chagrin), but later consents that they are friends.
** Haruhi bemoans having to constantly explain that Koizumi isn't her boyfriend, too. She doesn't view him anything as more than a friend, even though [[spoiler:Koizumi wishes things were different]].
* HeroicSacrifice: This is PlayedForLaughs in during chapter ten (episode three in the anime), when Haruhi "sacrifices" Koizumi and Kyon to Tsuruya in order to kidnap Mikuru. The two guys are easily "defeated", and as the Tsuruya prepares to attack Haruhi, she's stopped by a teacher who says jumping down a flight of stairs is risky. While Tsuruya is being lectured, Haruhi uses this opportunity to "steal" Mikuru away to the Literature club.
* HeterosexualLifePartners: Ryōko is Yuki's neighbor, but visits Yuki's place so often and minds over so many aspects of her life that they might as well be related. Similarly, Tsuruya and Mikuru are always seen together, with Tsuruya regarding herself as Mikuru's guardian.
** Kyon and Haruhi seem to be moving into [[PlatonicLifePartners the opposite-sex version]]. They have elements of their [[StrangeMindsThinkAlike odd connection]] from the original series, in that she opens up to him more than almost anyone else, but it seems to be more of a VitriolicBestBuds thing than romantic.
* HostileShowTakeover: Haruhi, despite not being a student of North High, quickly takes over the Literature club room, and brings in much of the antics that she does in the original series.
* HotSpringsEpisode: Episodes seven to nine in the anime (and the corresponding chapters in the manga) follow the group as they vacation at a hot springs.
* HotTeacher: Ryōko changes into a suit while tutoring Kyon, prompting him to wonder why she changed her clothes.
* HypercompetentSidekick: Ryōko is [[TheAce exceptionally skilled]] with school and housework, further finding the time to help Yuki out, and gives her encouragement when the latter is feeling down. However, her abilities have their limits: [[spoiler:she eventually gives up on a textbook problem that Haruhi goads her into trying to solve]].
* IdentityAmnesia: After her [[spoiler: near-accident during chapter twenty-five, Yuki suffers from temporary dysmnesia. While she still retains her memories, she no longer recognises them as her own and is effectively [[EmotionlessGirl a completely different person]]]]. This aspect is treated quite seriously, as her friends [[spoiler: come to terms with how to best interact with the alternate Yuki as a distinct person, who fears being regarded as just a sickness waiting to go away when for her being "cured" sounds frighteningly similar to death]].
* ImaginaryLoveTriangle: Tsuruya initially acts under the pretense that Yuki and Mikuru are rivals for Kyon's affections, despite Mikuru's protests otherwise.
* JapaneseSchoolClub: With the entire SOS brigade present, it's hard to remember that the bulk of the story takes place in the Literature Club.
* JerkWithAHeartOfGold: Despite frequently harassing Kyon for "two-timing" on Mikuru and generally enjoying extracting whatever entertainment she can from others, Tsuruya also helps with the literature club's Christmas party, shares her family's discount at a hot springs and hotel, and hosts everyone at her family's villa and private beach during summer vacation.
* JustFriends: [[spoiler:Haruhi and Koizumi are merely friends; she befriended him while he was adjusting to a new school, and eventually he, fell in love with her]].
* LastNameBasis: Despite being long-time friends, Yuki and Ryōko typically call each other by their family names.
* LighterAndSofter: As it is a SliceOfLife romantic comedy, the atmosphere in ''The Vanishing of Nagato Yuki-chan'' is much more relaxed relative to that of the original series.
* LoveConfession: While attempts are quite frequent, circumstances constantly cause [[spoiler: them to fail]]. The most poignant instance [[spoiler:occurs with Yuki's alternate personality making her feelings known. However, she does so with the knowledge that she'll [[DyingDeclarationOfLove cease to exist]] once she fully reintegrates with Yuki's original identity]].
* LoveEpiphany: As the manga progresses, both [[spoiler: Kyon begins to realise he's in love with Yuki after alternate Yuki makes her LoveConfession to Kyon]].
* LoveTriangle: Elements of a love triangle are gradually appearing.
** Haruhi supports Yuki's feelings for Kyon wholeheartedly, but there have been hints of her feelings for Kyon. Recently, it seemed chemistry was starting to bloom after Kyon pulls Haruhi out of the river, and she starts to feel something strange when Kyon pulls a John Smith-esque line. Later, Yuki walks in on Haruhi giving Kyon (obligation) chocolate during Valentines' Day, where Haruhi explains that she does feel a little bit of affection towards Kyon, stating that she "doesn't dislike him" to Yuki.
** Early on, Yuki saw Haruhi as a rival to be emulated, even in impossible things like having a ponytail.
** During the "Disappearance Arc", a love triangle materialises, involving Kyon, Yuki, and [[spoiler:Yuki's amnesiac alternate personality]]. Specifically, [[spoiler:alternate-Yuki confesses to Kyon just before Yuki's original identity reawakens, clarifying her feelings to Kyon. However, Kyon becomes conflicted as to whether he's honestly attracted to Yuki, or if she's just a stand-in for the now-faded alternate identity that managed to steal his heart during her brief life]].
* MeaningfulName: The Vanishing Of Nagato Yuki-chan [[spoiler:refers to Nagato [[NotHimself disassociating from her memories]] after nearly being hit by a car and her original, cheerful personality temporarily "vanishing"]]..
* {{Meganekko}}: Yuki is the only member of the main cast to sport a pair of her glasses.
* MistakenForGay: Mikuru's efforts to rally Yuki's courage in giving her Valentine's Day Chocolate results in some misunderstanding: she states that she'd be glad to get chocolate from Yuki if she were male, and while Yuki is aware of what she means, Tsuruya and Ryōko view it as a LoveConfession and proceed to tease Mikuru about it.
* MomentKiller: Tsuruya, Kyon's sister and Ryōko have a propensity of ruining such moments.
** In particular, Ryōko unintentionally ruins things for Yuki during the Christmas party, when she opens the window to watch the snowfall while the two are outside alone.
** Ryōko also walks in to the club room on Kyon and Yuki supposedly hugging, which happened because [[NotWhatItLooksLike Kyon took her game away to tease her a little]].
* MyBelovedSmother: Ryōko sometimes acts in this manner towards Yuki.
* MythologyGag: Numerous references to ''The Melancholy of Suzumiya Haruhi'' are made:
** In the first episode, Ryoko hands off the bags of groceries to Kyon after shopping. She remarks that her hands are cold, and the camera tilts to the same angle in the original series, right before the original Asakura ran at Kyon with a knife. Here, she simply places her hands on his face to warm them up.
** Haruhi attempts to recreate the "I am here" message to aliens on the field. Since Kyon doesn't know her, she doesn't run into him, instead asking Yuki to write said message.
** Kyon responds to Haruhi's question "Do you think kappas really exist?" with a "Dunno. Maybe they do." This mirrors the Haruhi and "John Smith" conversation.
** A flashback is shown to an alternate version of the [[spoiler:John Smith scene, although Kyon does not remember]].
** Mikuru has a star-shaped mole on her chest, and initially, only Tsuruya is aware of this.
** Like in ''Manga/HaruhiChan'', Mori is the physical education instructor.
** Yuki offers Kyon the club signup sheet in the same manner as she had in the light novels.
** Haruhi's [[TheReveal big reveal]] about her "ambitions" is featured, albeit under different circumstances.
** Haruhi dresses up in Kyon's sports uniform so as not to stand out in North High; Kyon even asks her to do her hair up in a ponytail.
** When Yuki gives a confusing explanation for a math problem, Ryōko says "It's like she's speaking some kind of alien language," referencing how Yuki's gibberish sounds exactly like the original Yuki's incantations.
** In the anime, Haruhi and Tsuruya square off with {{Animal Battle Aura}}s of [[Manga/HaruhiChan Haruhi dressed as a sheep dog and Tsuruya dressed as a swan]].
** During the Anime's version of the [[HotSpringsEpisode Literature Club field trip]], after bathing in the onsen, Haruhi declares it to be the 15,498th Ping-Pong meet, alluding to the number of repetitions quoted in the Endless Eight arc.
** Some of the wishes written for Tanabata are similar to those from 'The Melancholy of Suzumiya Haruhi''.
** Ryōko mentions that if she succumbs to stress, she just might knife Kyon.
** Chapter thirty-eight begins with [[GroundhogDayLoop a familiar scene concerning a (not-as-dramatic) declaration of not having done one's summer homework]], although this time, there is no [[MemeticMutation endless recursions of time]].
** Everyone's roles during the previous year's SchoolFestival in chapter forty-one are call-backs to the original series: Yuki was a fortune-teller, while Haruhi wrote, filmed, and directed her own movie, with Koizumi as the star. Unfortunately, she got bored and shelved it once it got into post-production. In said movie, mysterious transfer student Koizumi awakens to his PsychicPowers and uses them to fight giant monsters. Haruhi and Tsuruya also filled in for absent members of a band at North High's festival.
** Ryōko is seen humming Hare Hare Yukai while the audience gets a glimpse of her insane knife skills (while cooking).
** One of Ryōko's character songs is called "LOVE EDITION", mirroring one of her original songs, "COOL EDITION".
** Episode ten is titled "Someday in the Rain", shared with the main series' first season finale.
** Kyon's sister tries to sneak along to Kyon's trip to the beach, hiding in his duffle bag and dropkicks him like she did in ''Manga/HaruhiChan'' upon being discovered.
** Haruhi hums "Bouken Desho, Desho?" (the first opening of the main series) during the final episode.
** The final episode mirrors Endless Eight's plot, and [[spoiler: it turns out that [[TheStinger Kyon even forgot to do his summer homework]].]]
** Yuki fondly remembers Kyon helping her get a library card, as he did in the series, but in a manner that was closer to the post-credits scene from the Disappearance movie.
** Volume ten has a callout to Endless Eight when Kyon's little sister remarks "Kyon-kun, phone" in response to a text Kyon's received.
** Objects resembling Kimidori-san, [[Manga/HaruhiChan the balloon dog]], makes an appearance every so often in the background.
* NoAntagonist: With a lack of [[AliensAreBastards bastard-like aliens]], [[EldritchAbomination amoral data entities]], and [[ThePsychoRangers rival time-travelers and espers]], very little stands in the way of Yuki achieving her wish to become closer to Kyon, barring [[CanNotSpitItOut herself]].
* NormalFishInATinyPond: Ryōko is a good student at North High, but she's blown away by the math problems Koyouen students routinely solve.
* NotAMorningPerson: Ryōko regularly has to push Yuki through her morning routine to make sure the latter is ready for school on time.
* NotWhatItLooksLike:
** Yuki walks in on Haruhi giving Kyon chocolate on Valentine's Day, throws away the chocolate she had been planning to give him, and runs out of the clubroom at full speed. It turns out that [[spoiler:Haruhi's is just obligation chocolate, identical to what she then gives Koizumi]].Later, Yuki reveals that [[spoiler:she left out of consideration, and meant to present hers later - she's quite alarmed to discover she dropped hers]].
** When Kyon asks Ryōko for some tutoring, she tells him that relying on her right away is bad. He then decides to ask Yuki instead, prompting Ryōko to immediately change her mind about the tutoring. When he points out her initial refusal, she strong-arms him into agreeing. Yuki, meanwhile, has an ImagineSpot and thinks the two are secretly sharing a romantic moment, before rationalising it as NotWhatItLooksLike... just not the NotWhatItLooksLike [[WrongGenreSavvy that actually happened]].
** Ryōko walks into the club room while Kyon and Yuki are supposedly hugging. She then slowly backs out of the room and closes the door. In reality Kyon took Yuki's game away, then jokingly kept it out of reach while she attempted to get it back, bumping into him in the process. A moment later he feeds Yuki a little bit of his food to make up for teasing her, and Ryōko once again walks in on it. She hilariously tries to exit the same way she did the first time.
* ObliviousToLove: Kyon does not seem aware of Yuki's feelings due to the fact she CannotSpitItOut.
* {{Otaku}}: While not quite as passionate about games as her ''Manga/HaruhiChan'' incarnation, Yuki often plays games well into the morning hours, much to Ryōko's displeasure.
* ParentalAbandonment: Ryōko's parents are working overseas, and little is known about Yuki's parents, save when a doctor mentions their absence in passing.
* ThePiratesWhoDontDoAnything: The Literature Club's activities are largely unrelated, and save an exhibit for a culture festival involving the collection of literature, the club's members usually spend their days relaxing together.
* ProductPlacement: Kyon, his sister, and Yuki play a Monster Hunter-like game on the Nintendo 3DS. In the anime, this changes to Yuki's love of playing visual novels on her UsefulNotes/PlayStationVita.
* PublicDomainSoundtrack: 'Maurice Ravel's ''Pavane for a Dead Princess'' [[https://infinitemirai.wordpress.com/2015/12/18/pavane-for-nagato-yuki-remarks-on-the-musical-score-in-the-disappearance-of-nagato-yuki-chan/ is used as a lietmotif of sorts for Yuki]]. ''Pavane for a Dead Princess'' begins quietly, with a slow tempo; as the song continues, it transitions from pianissimo to fortissimo, without losing its slow tempo. Likewise, Yuki is content to do things at her own pace, but as she gains more confidence, her actions become bolder.
* RealPlaceBackground: In line with the original series, the anime offers a faithful depiction of the town of [[https://infinitemirai.wordpress.com/2012/04/27/nishinomiya-hyogo-home-of-the-melancholy-of-suzumiya-haruhi/ Nishinomiya]]; many landmarks are even shown in their renovated state.
* RecycledSoundtrack: Motifs from the original anime's soundtrack are used on some occasions, especially in scenes with Haruhi.
* TheReveal: Haruhi's makes her declaration about longing to meet "time travelers, aliens and espers", but the context differs compared to that of the original.
* RubberFace:
** Ryōko does this to Haruhi after finding out the latter had Yuki quickly sign a permission slip to allow her and Koizumi to enter their school for club activities despite not being students at the school.
** Haruhi in turn does this to Yuki when the latter starts getting apologetic about Haruhi doing everything for the Literature Club.
* RunningGag: Yuki's attempts to follow Ryōko's advice to get an early night before important days typically fail: unable to sleep out of excitement, she typically ends up staying up all night, playing video games. [[spoiler:Alternate Yuki gets into the same routine with books]].
* SchoolFestival: The school festival and accompanying preparations forms the focus for much of the sixth volume.
* SeriousBusiness:
** Tsuruya and Ryōko become very involved during the Mikuru vs Yuki contest to see who's more popular, reaching the point where both Mikuru and Yuki are no longer the contestants, as Tsuruya and Ryōko going head to head against one another.
** After declaring Ryōko as North High's representative against Haruhi's school and saying that an insult to their school was an insult on her, Ryōko openly challenges Haruhi to a mathematics quiz and is promptly bested.
* ShipperOnDeck: Ryōko ships Yuki with Kyon. In fact, most of the girls do (even Haruhi, who has some degree of affection for Kyon). Tsuruya attempted to ship Mikuru and Kyon for a while, but neither Mikuru nor Kyon [[JustFriends shares these sentiments]]. Kyon's sister also appears enthralled with notions of her brother and Yuki being a couple.
* ShipTease:
** Most moments deal with Kyon and Yuki.
** There's also a few instances involving Ryōko and Kyon, although it might just be that she's trying to spur Yuki into being more proactive herself.
** Hints of Haruhi and Kyon begin arising when Haruhi realizes that [[spoiler: Kyon is John Smith]], complete with mild tsundere tendencies on Haruhi's part, in the anime.
** ShipSinking: In contrast to the regular series, Kyon and Mikuru view one another as JustFriends..
* ShooOutTheClowns: For the entirety of the "Disappearance" arc, Mikuru, Tsuruya, Haruhi and Itsuki are absent. This coincides with the fact that in-universe, both schools are close to major exams and thus, the others are busy preparing for their exams.
* SingleTear: Yuki lets a single tear fall from her eye when Kyon replies to her [[spoiler:LoveConfession]] with one of his own.
* SkinshipGrope: Mikuru suffers this at Haruhi and Tsuruya's hands during their excursion to the hot springs.
* ShrinkingViolet: Yuki is one in this series, being quite shy and often unwilling to do much on her own without prodding from someone else, but as children, [[spoiler: ''Ryōko'' was quite shy and tended to depend on Yuki]].
* SpotlightStealingSquad: Despite the series not bearing her name, Haruhi's presence is very noticeable in the anime.
* TheStinger:
** At the end of episode two in the anime, Yuki forgets her meeting in the park with Haruhi to capture Santa. As she walks by with Kyon the next day, Haruhi then leaps out of the bushes and collapses, suggesting she had been there all night.
** Ryōko tells Yuki to come up with excuses to see Kyon over the summer break since they won't have club meetings as episode nine draws to a close, and shortly after, [[spoiler: Yuki is involved in a near-accident while crossing the road]].
** The final episode hits audiences with a BrickJoke several episodes in the making -- [[spoiler:Kyon forgot to do his summer homework]].
* StraightMan: Kyon is the most level-headed and usually makes snide remarks on events around him. There are cases where [[GenkiGirl Haruhi]] also fulfills this role, in response to Ryōko's ShipperOnDeck actions.
* StrangeMindsThinkAlike: Similar to the original, Kyon and Haruhi have this dynamic. Similarly, [[spoiler:Yuki confesses to Kyon at the same time that he was considering doing the exact same with her]].
* StrongerThanTheyLook: Tsuruya effortlessly ascends the hill that exhausts Kyon, Koizumi, and Yuki en route to the stargazing spot near the resort, all while carrying Mikuru piggyback for the full length of the hike.
* TeamMom: Ryōko fulfills this role for her friends, to the point where Tsuruya teases her with the idea, after Ryōko manoeuvres Kyon into some alone time with Yuki at the Christmas party. Similarly, Haruhi views Ryōko as a disapproving mother-in-law over Yuki and Kyon's relationship.
* TemptingFate: In episode nine, Koizumi and Kyon are relaxing in their room at the hot springs resort. The latter mentions that having some nice and quiet every now and then is good. The peace is disturbed almost immediately as Haruhi shows up, and says they're going to spend the whole night playing games together.
* ThemeTuneCameo: In the very first episode of the anime, Ryōko hums ''[[LightNovel/HaruhiSuzumiya Hare Hare Yukai]]'' while she cooks. In the final episode, Haruhi hums ''Bouken Desho, Desho?''.
* TheyDo: By volume eight in the manga, it's shown that [[spoiler: Yuki and Kyon confess their feelings for one another. There are no distractions and no circumstances preventing them from doing so, and subsequently, the two begin dating]].
* TimeSkip:
** The first volume of the manga skips forwards seven months after Ryōko's conversation with Yuki, leaving out details pertaining to how Kyon ended up joining the literature club until later.
** The final volume skips over much of Yuki and the others' third year, primarily showing a montage of the events of several months, eventually leading up to [[spoiler:Ryōko's depature]]
* TookALevelInKindness: Kyon and Haruhi are both noticeably nicer than their original characters, but this is most apparent with Ryōko, whose psychotic tendencies are discarded entirely, even though she can project a substantial aura of menace whenever angered.
* {{Tsundere}}: Haruhi fulfils some of the requirements for being Type B, although this is played with in that she doesn't get awkward when it's necessarily someone she's crushing on; instead, she becomes a little shy whenever someone thanks her (she had elements of this in the original, although her JerkAss personality means she's better classified as Type A).
* UncannyValleyGirl: This averted in this series for Ryōko Asakura (contrasting the main ''Haruhi'' series); she doesn't smile all the time or always have a voice of concern. She seems to have an actual normal range of emotions and they run deeper than skin-deep. From just starting the series, one can tell she's normal in this series, and she comes across very differently from how she comes across in the ''Haruhi'' series.
* UnwantedAssistance: After the above FanService happens, Yuki asks Kyon what he thought of what he saw. After worrying about how to answer, he looks over at Ryōko, who holds up a cue card that says, "It was sexy (especially your belly button)".
* UnwantedHarem: While not every girl is into Kyon, the later chapters predominantly feature a large number of girls congregating in the Literature Club room.
* ValentinesDayEpisodes: Episodes four and five in the anime, and the respective chapters in the manga, are set around Yuki's wish to gift Kyon some chocolates during Valentines' Day.
* VisualPun: The anime's opening has several of these:
** The line that can be translated as "Whether it's a sunny day, a rainy day or a snowy day" is illustrated by a shot of the school grounds on a sunny day, followed by one on a rainy day, followed by... Yuki[[note]]The Japanese word for snow also being pronounced ''yuki''[[/note]] walking down the corridor.
** The line that gives the song most of its title, ''Fure fure yo'' ("Fall, fall!" in relation to rain or snow), is accompanied by the girls swaying their hips from side to side. ''Fure'' can also be the imperative of a different verb meaning "to shake".
* VitriolicBestBuds: Ryōko and Tsuruya initially regard each other in this manner at first, but they develop a friendly rivalry as they get to know one another better. Ryōko and Haruhi later develop a similar dynamic, as do Kyon and Haruhi. In the latter case, Kyon is put-off off by Haruhi's antics, but does seem to understand her more than almost anyone else.
* WeUsedToBeFriends: Yuki and Ryōko were close friends with Kimidori in the past but began drifting apart when Kimidori joined the student council.
* WhamLine:
** From chapter twenty-six: "... I thought so. Just one more thing. [[spoiler:Who are you?]]"
** From chapter thirty-three: [[spoiler:"I... Kyon, I love you."]]
* WomanInWhite: In the "Vanishment" arc, when Yuki is being introspective, she is often wearing a white dress in her thoughts.
* YouGottaHaveBlueHair: The odd hair colours are retained despite this being a more realistic universe, and Mikuru's hair even has a colour gradient now.
