''Who... are you?''

''Who... am I?''

''Ever17'', the second game in the ''Infinity'' series, is a VisualNovel made by the now-sorta-defunct studio KID (while bankrupt, key members of the company split off into three companies: Cyberfront, 5pb., and Regista), and is one of the very few visual novels to be officially translated into English (by a company called Hirameki International, now ''completely'' defunct). It tells the story of six (or is it five? Or seven?) young people who are trapped in an underwater theme park called [=LeMU=] when it unexpectedly springs a leak. They then have 119 hours to find a way to escape before the place implodes and they all die. It's a little like ''The Poseidon Adventure'', if ''The Poseidon Adventure'' were set in the future and had sinister German pharmaceutical companies and some interesting uses of quantum physics. [[{{Dissimile}} So not much like it at all, really.]]

The game has two first-person protagonists, each with their own set of paths. The first is an amnesiac boy known only as the Kid; the second is Takeshi, an ordinary college student. Other major characters include Coco, a fourteen-year-old who looks ten and acts about five; You (it's a nickname, [[WhosOnFirst not a pronoun]], although it's still pronounced "yuu," and not "yo"), a cheerful and friendly employee of [=LeMU=]; Sara, an imaginative girl who is a little obsessed with ninjas; Sora, a calm and mature woman who also works at [=LeMU=]; and Tsugumi, an enigmatic and unfriendly girl who seems to want little to do with anyone else.

The game is also a huge MindScrew and possessed of a plot so twisty that any attempt to explain or describe it more thoroughly would, by necessity, involve spoilers. Speaking of which, beware of falling spoilers in the trope examples section; some tropes are big spoilers just by being listed.

A {{manga}} adaptation (based on the Xbox 360 version of Tsugumi's Route) [[http://www.famitsu.com/comic_clear/se_ever17/ ran from 2011-2012]] ([[http://www.mangareader.net/ever-17 translated chapters]]).

Two {{DramaCD}}'s were made which act as [[PostscriptSeason supplemental stories]] for what occurs after the game's ending. Fan translations of the plays can be found [[http://www.youtube.com/watch?v=a05MYATZERw&list=PLB24224557266598C here]] and [[http://www.youtube.com/watch?v=vhgNKp8N0d8&list=PLBD73D7CF2A812A57 here]].

See also {{Never 7}}, {{Remember 11}} (the other two games in the series),[[TwelveRiven 12Riven]] (a spinoff of sorts that takes place in a similar setting), {{Code18}} (the "official" fourth game in the series, though without any input of the original staff), [[InputOutput [=I/O=]]], [[VisualNovel/RootDoubleBeforeCrimeAfterDays Root Double]] (directed/written by the game's director/main writer), and VisualNovel/NineHoursNinePersonsNineDoors (directed/written by the other main writer), all which have similar themes and setups.

'''Due to the nature of the game, the trope page contains many SPOILERS even after following our usual spoiler policy. If you are the type of reader who is bothered by them, probably you shouldn't look at this page at all before playing the game.'''
----
!!Provides examples of:
* [[spoiler:AGodIsYou: You, the player, are actually Blick Winkel.]]
* [[spoiler:AbsurdlyYouthfulMother: Yubiseiharukana and Tsugumi.]]
* [[spoiler:ActionMom: Tsugumi, if "After You've Gone" is to be believed, is pretty decent in a fight.]]
* AllThereInTheManual: [[spoiler:The origins of the Cure Virus, as well as the significance of Tsugumi's friend Julia and Shigezo Morino, is only revealed in {{Never7}}, the first game of the series.]]
* AloofDarkHairedGirl: Tsugumi is tall with long, dark hair and is highly distanced from the rest of the cast. If nothing else, Takeshi is intrigued enough to follow her around a lot.
* AmbiguousSituation: Unlike most of the mysteries, it's never made clear what exactly happened in the game of kick the can.
* ArcNumber: 17, 34 or other numbers divisible by it.
** A few of the times/dates have 17 in them.
*** The most obvious one, being that the year is 2017. [[spoiler:The seventeen-year time gap obviously counts too.]]
*** Coco's birthday falls on December 17th, 2002.
*** [[spoiler: BW comes into existence on May 1st, 2034 at 3:17 PM.]]
** 17 meters (56 feet) between each floor of [=LeMU=].
** 17 minutes in the decompression chamber in the prologue.
** Takeshi mentions the Ninneko Song 17 when Coco starts calling him [[InSeriesNickname Takepyon]].
** 17 seconds for the lights to come on after repairing the generator. [[spoiler:In 2017, Tsugumi correctly times this by pressing the switch on Takeshi's count of 17, ending with 0 as the lights come on. In 2034, You/Sara/Kid press the button on Kaburaki's count of 34, and Sara counts 17 as the lights come on.]]
** 34 rings in Tsugumi's Jewel Chocolate metaphor to Kid. [[spoiler:Like the above example, this is a reference to the 2034 incident being a repeat of 2017, in addition to Tsugumi's hinting that she's figured everything out, and is playing along for both the cause of rescuing Takeshi/Coco, as well as collecting her "rings," being her children Sara and Hokuto.]]
** You's father disappeared 17 years ago, when she was 1 year old.
** [[spoiler:The password to the system is a haiku, which is 17 syllables long (5-7-5)]]
** [[spoiler:The Tief Blau virus is labeled "Tief Blau 2017-Rev.17"]]
** [[spoiler:Likewise, the Cure virus is known to affect the p53 function on the 17th chromosome.]]
** [[spoiler:Due to her condition, Tsugumi stops aging, making her [[TitleDrop forever 17]], at least physically.]]
** It's even expressed in the game's internal logic: Getting Tsugumi's Good End requires 17 affection points.
* ArtisticLicenseBiology: Tsugumi states that after seven years, every cell in the human body has died and been replaced. The neurons in the cerebral cortex are ''never'' replaced.
** Maintaining the complex at six atmospheres of pressure and expecting people to be comfortable? Including children and elders? They transition over 17 minutes, but still.
* BilingualBonus: In tandem with LostInTranslation and ChekhovsGun, the [[spoiler: [[http://imageshack.us/photo/my-images/86/passwordpx2.jpg/ haiku password is actually alluding to the characters!]] Crazy.]]
** Also, if you happen to know both Japanese and German, you will make the connection between [[spoiler: Sora and the "Himmel" door before it actually comes up in the story. After all, both Sora and Himmel mean Sky.]]
* {{Bishonen}}: [[spoiler:Takeshi and Hokuto. At first you wouldn't think Takeshi is, but that's because it's not really him. The real Takeshi is described as being ridiculously good looking.]] On a different note, it's kind of amusing when even a {{bishonen}} trope involves major spoilers.
* BittersweetEnding: [[spoiler:The "good endings" that aren't the true final ending, mainly Tsugumi and Sora's endings.]]
* BlindIdiotTranslation: Not as bad as some, but it has its moments.
** A line that's supposed to be like "Of course I know what a hacker is" became "Naturally, I knows the hacker", which became a minor {{meme|ticMutation}} among the fanbase.
*** [[spoiler:Whenever someone posts a screencap of that line, a post of "[[WhosOnFirst Oh You]]" may follow.]]
** A more ''literal'' example would be near the beginning, where someone in a tanuki suit (which, in the first place, is really a lemur suit) being bitten by a girl who is being bitten by a dog. The dog looks ''nothing at all'' like the tanuki, and yet the game calls the dog a "smaller tanuki". And then, mind-bogglingly enough, the game later states the obvious and tells you that it's not a tanuki.
** Not to mention all the "find and replace" errors, as in "youth" with "Kid". The result gives us sentences like "Kidere" and "Kidink," instead of "You there" and "You think".
*** Which is particularly ironic, considering a find-and-replace error is an actual plot point during Kid/You's scenario. [[spoiler:This is how You'aki' discovers that mentions of her (grand?)parents were purposefully deleted from LEMMIH.]]
** "Tooling test" was suppose to be "Turing test".
* BookEnds: [[spoiler:Both the prologue and the epilogue start on a boat, narrated by Takeshi.]]
* BreakTheCutie: [[spoiler:You and Kaburaki after the first incident.]]
* BrokenBird: Tsugumi. [[spoiler:''Twice''. You"haru" and Kaburaki have essentially become this by 2034.]]
* ChekhovsGun: Too many to list. [[spoiler:Archimedes principle. The cryogenics function on the pods. The coffee machine. The lemur suit. "Life readings: 6." The broken mirror in the bathroom. Can you swim 100ft? "I am You." You's mom had a robot dog...]] EVERYTHING is important.
* ChickMagnet: [[spoiler:Takeshi. Getting the affection of Tsugumi, Sora and You'haru'.]]
** [[spoiler:Even Sara falls for him, who answers 'papa' when asked of her ideal boyfriend in the audio CD.]]
* CloningBlues: [[spoiler:The You in the Kid's routes (Yubisei''aki''kana) is a clone of the You in Takeshi's routes (Yubisei''haru''kana). Unlike most examples of this trope, however, the one being cloned did it willingly.]]
* ClosedCircle: More or less the game's premise.
* ContinuityNod: Several to Never7, such as [[spoiler:the mentioned characters of Shigezo Morino, the father of Izumi and Kurumi Morino, and Julia, one of the origins of Cure Syndrome.]]
* CurtainsMatchTheWindow: ''Everyone''.
* [[spoiler:DeathBySex: Takeshi dies shortly after having sex with Tsugumi. Sort of.]]
* [[spoiler:DeadPersonImpersonation: 2017's Kid is playing Takeshi's role in 2034, although real Takeshi is NotQuiteDead at that time.]]
* DeathSeeker: Tsugumi.
* DefrostingIceQueen: Tsugumi. [[spoiler:Then she refrosts again, and then defrosts permanently by the True End.]]
* {{Determinator}}: Takeshi. The game even states [[spoiler:that he's actually probably drowned at this point]], and he still gets up and saves the day. After having enough done to him to kill him in about six different ways without eating in over a day because he ''threw up his last meal after swimming through frigid water'' and without resting at all. Unless you consider [[spoiler:being dead at the bottom of the ocean "rest".]]
** [[spoiler:All of the survivors of the 2017 incident probably count. Organizing a 17-year-long [[DidYouJustScamCthulhu scam]], using your children as pawns, to trick a hyperdimensional being into retconning history takes some ''balls''.]]
* DeusExMachina: [[spoiler:{{Invoked|Trope}} by survivors of 2017's incident, with '''[[PlayingThePlayer the player]]''' being Deus.]]
* DiabolusExMachina: [[spoiler:Tsugumi's good end, where she and Takeshi board the remote sub and escape just as IBF collapses around them, cue them talking about the future and the forthcoming happy ending right? Nope, the sub just happens to run out of battery power and starts sinking at the conveniently worst possible moment, necessitating Takeshi's HeroicSacrifice to save Tsugumi's life, and the TearJerker DownerEnding.]]
** [[spoiler:Not to mention it gets worse in Coco's route, where you learn exactly what happened after that. [[DeusAngstMachina Poor Tsugumi just can't catch a break.]]]]
* DisappearedDad: Part of You's back-story.
* DitzyGenius: Sara is perhaps the silliest character, saying the silliest things (both how she says them and what she says, though a lot of it is lost in the English translation), but she is a genius, especially when it comes to computers. [[spoiler:Judging by the flashbacks, her silly personality seems to be due to associating with You.]] Coco is silly too, but she's a TokenMiniMoe so it's expected.
** You seems to be pretty smart too, but most of silliness seems to stem from the fact that she's a GenkiGirl.
* DoesThisRemindYouOfAnything: You demonstrates a point about perception to the Kid by making him cap a pen with one eye closed. The tip is slippery. It won't go in the hole. It's his first time doing this. See DoesThisRemindYouOfAnything page quote for details.
* DownerEnding: [[spoiler:Both of Takeshi's endings count, as well as all the bad ends. In Tsugumi's ending, Takeshi makes a last minute HeroicSacrifice to allow Tsugumi to escape to the shore while he drowns, as she cries for him not to die. In Sora's ending, not only does SHE not escape, but Takeshi is caught in the collapse and everyone but Tsugumi is slowly dying of Tief Blau without any available treatment. Luckily, the true end is NOT a continuation of THIS route.]]
** [[spoiler:It can be assumed that in the Sora arc, Tsugumi treated all afflicted persons on on her own, while Takeshi was unconscious. Otherwise he probably would not have been able to get to Sora, let alone survive the sudden decompression. Of course this still qualifies as a DownerEnding by a wide margin.]]
*** [[spoiler:Given how resistant Tsugumi is to that idea in her own route, and how hostile relations are between her and the rest at the end of the Sora route, that is quite unlikely. Most likely, either this was due to Takeshi being TheDeterminator, or he had gotten infected whilst in the Jellyfish Gondola.]]
*** [[spoiler:Then again, it is quite explicitly stated in Tsugumi's arc that Takeshi gets some of Tsugumi's blood in his mouth when they kiss. As this means he's infected with Cure, he quite probably can't even die from the pressure. But even if he survives, if he can't get up, the DownerEnding gets even worse.]]
* DyingDeclarationOfLove: [[spoiler:You to Takeshi in Tsugumi-Sora BadEnd.]]
* EarnYourHappyEnding
* EverybodyLives: [[spoiler:The True Ending.]]
* [[spoiler:EveryoneIsRelated: Out of the nine (ten if you count BW) main characters in the game, six are related to at least one other person (seven if you want to get technical).]]
** [[spoiler:To elaborate: Takeshi, Tsugumi, Hokuto and Sara are all a family; You'aki is and You'haru's daughter and clone; Yoichi (You's father) had a hand in the creation of Sora, and thus she also has some relation to You. There's also Coco "adopting" BW as her older brother (and boyfriend).]]
** [[spoiler:On the other hand, in a slight subversion, the game leads the player to believe that there's some relation between Coco and Sara. This is highlighted by the fact that they're the major missing link between Takeshi's routes and Kid's routes, they both appear in the same places, sing the same lullaby, and further promotional and extra art typically shows the two together. Fast-forward to the end and epilogue of the game, and there's neither relation nor any real interaction between the two. The Drama [=CDs=] don't have the two interact much either (justified in After You've Gone, given their circumstances).]]
* {{Expy}}: Most of the characters' personalities and archetypes are similar to characters from {{Never7}}.
** You is based off of Yuka.
** Tsugumi takes traits from Haruka and Saki.
** Sora's personality is very similar to Izumi's.
** Both Sara and Coco have traits from Kurumi.
* FaceDoodling: You and Sara do it to sleeping Takeshi. [[spoiler:Kaburaki, who was one of the survivors of the first incident, eventually had it happening to him in the second. He probably knew it was going to happen.]]
* FindTheCure: May 6th is devoted to this as everyone is infected with Tief Blau. [[spoiler:Ironically, [[IncrediblyLamePun the cure is Cure.]]]]
** [[spoiler:This is also pretty much the plot of both Drama [=CDs=], with Sora in "2035" and Sara in "After You've Gone".]]
* FirstGirlWins: [[spoiler:For both protagonists.]]
** [[spoiler:Although Takeshi (and initially, the player) doesn't realize that it's Tsugumi under the tanuki suit. The next girl would be Coco, who gets paired with Blickwinkel.]]
* FlatWhat: After eating a sandwich with Takeshi's special ingredients (sage, soy sauce, mayonnaise, Tabasco, etc.), Tsugumi claims it tastes like pizza, and Kid's first thought is this.
* {{Foreshadowing}}: Lots of it, inside each path and in a game as a whole.
* [[spoiler:GasChamber]]: The [=LeMU=] incident [[spoiler:(the first time around, that is)]] turns out to be an unplanned version of this.
* GenerationXerox: Deliberately invoked on [[spoiler:Yubisei''aki''kana by her mother, in order to make her as similar to her mother as possible, as part of the BatmanGambit to trick Blickwinkel. As this includes tricking her into thinking she has [[DisappearedDad the same backstory]] as her mother, You is obviously [[CallingTheOldManOut not happy when she finds out]].]]
* GenkiGirl: You, Sara, and Coco, to varying extents.
* GetAHoldOfYourselfMan: Takeshi has the option of using one of these on the Kid. Subverted if he does do it, as he instantly regrets it and is [[WhatTheHellHero looked down upon by the others]].
** [[spoiler:If you chose to hit him, Tsugumi's affection points actually go up.]]
* GoMadFromTheRevelation: [[spoiler:The Kid has brief moments of mental stress no less than three times when he starts to discover his past. You does this rather comically when she learns part of the Kid's past as well.]]
* GoldenEnding: [[spoiler: Coco's route, which requires every good route to be completed to be unlocked. Coco and Takeshi survive, everyone is reunited, and all the answers are revealed.]]
* GratuitousEnglish: The message at the end of every route [[spoiler:except Coco's]].
-->[[spoiler:''This story is not an end yet. Because only you are in the infinity loop.'']]
* GratuitousFrench: "Comprendez-vous?" As anybody who knows French can tell, the d doesn't belong there, but that can be explained as Takeshi just not being fluent.
* GratuitousGerman: LEMMIH's system declares its announcements in German. Also, [[MegaCorp Leiblich]] originated from Germany.
** There's also [[spoiler:Tief Blau (Deep Blue)]] and [[spoiler:Blick Winkel (View/Perspective)]].
* GoOutWithASmile: Several characters in bad endings.
* [[spoiler:GroundhogDayLoop: [[GratuitousEnglish This story is not an end yet. Because only you are in the infinity loop.]]]]
** [[spoiler:Different from most other loops in that, like the game says, it's only Blickwinkel that's experiencing the loop, continually going back and forward in time to 2017 and 2034.]]
* HalfHumanHybrid: [[spoiler:Hokuto and Sara]] are classified as such, though not a true example of this trope.
* HalfIdenticalTwins: {{Averted}}. [[spoiler:Sara and Hokuto look very little alike.]]
** [[spoiler:StrongFamilyResemblance]]: Also {{averted}}. [[spoiler:Hokuto and Sara bear little resemblance to either of their parents.]]
*** [[spoiler: Hokuto looks notably different than his father, though he is still handsome. Also, Hokuto is much smarter than Takeshi, though less decisive and reckless.]]
* HandBehindHead: In the Kid's route, Takeshi's right hand is ''always'' behind his head.
* HeadPet: Pipi, sometimes.
* HealingFactor: [[spoiler:Tsugumi.]]
* HeliumSpeech: Used in the prologue by Coco. Combined with the fact that her normal voice is already high-pitched... your eardrums will explode.
** In the remake, Takeshi also has this in the same scene (which makes more sense in hindsight, since all voices, his included, should sound like this without the headphones).
* HeroicSacrifice: [[spoiler:Tsugumi's Good Ending ends with one of these.]]
* HiddenEyes: A strange version of this: while we never see either Takeshi or the Kid while playing as them (except in some [=CGs=], but even there they are not fully seen), we see exactly what the other looks like while playing from the opposite perspective. [[spoiler:Or so we're lead to believe.]]
** On Tsugumi's face when she [[spoiler:proves her HealingFactor by "killing" her pet hamster that has the same condition]] and then proceeds to [[spoiler:lay out her {{backstory}}]].
* HonoraryUncle: [[spoiler:A variation. Coco begins to call Takeshi and Tsugumi "father" and "mother." By the end, she's calling Blick Winkel "brother."]]
* HopeSpot: See the DiabolusExMachina above.
* HumanPopsicle: [[spoiler:Takeshi and Coco are both cryogenically frozen in order to avoid dying of Tief Blau.]]
* IdiotHero: Takeshi, at times. [[spoiler:Both routes, actually -- Kaburaki does a pretty good job of mimicking it, compared to his original, [[ShrinkingViolet somewhat low-key]] personality.]]
** [[spoiler: Hokuto/Blick Winkel also have their moments. The most notable is at the end of the final path - my friends are cryogenically frozen at the bottom of the ocean, and have been for 17 years already? Well, let me just grab a stone and jump and sink to the bottom of said ocean, instead of just calmly asking someone for a submarine. You"haru" even calls Hokuto/BW out on it.]]
* {{Immortality}}: [[spoiler: Shigezo Morino lists three kinds of immortality when talking to You'haru: [[TheAgeless immortality of body]], [[BrainUploading immortality of memory]] and [[OurClonesAreIdentical immortality of genetics]]. In the course of the story it becomes apparent that Tsugumi represents the first, Sora represents the second, and You represents the third.]]
* IncurableCoughOfDeath[=/=]BloodFromTheMouth: Symptoms of Tief Blau.
* InformedSpecies: That plump, vacant-eyed mascot is a lemur, not a tanuki.
* IronicEcho: [[spoiler: During his HeroicSacrifice in the Tsugumi route, Takeshi says "Don't touch me" when Tsugumi tries to stop him, which is what she said early on in their relationship when he tries to stop her from leaving in disgust.]]
* KarmicDeath: [[spoiler:All of Leiblich's KickTheDog moments, such as capturing Tsugumi, Hokuto, Sara, and Dr. Tanaka, developing and accidentally releasing Tief Blau, and various experimentation comes to bite them back in the ass as they all contribute to the Japanese branch's eventual shut down at the end of the game.]]
* LaserGuidedAmnesia: The Kid.
* LethalChef: There's a reason Takeshi was designated as the one to cook the chicken sandwiches, as one scene proves. You's, Kid's and Coco's sandwiches apparently don't taste bad, but they end up looking bad. Coco's sandwich in particular has a long list of ingredients that probably don't go well together.
* LimitedWardrobe: [[spoiler:While "Takeshi" and Tsugumi's clothing being the same in 2034 is justifiable, You"aki" still wears the same casual clothes that her mother did in 2017, despite 17 years having gone by.]]
** [[spoiler: The LeMU uniform remaining exactly the same after it being detroyed, rebuilt, and 17 years having passed, is also a stretch.]]
* LongLostRelative: More of a [[spoiler: Long Lost Family]] in this case.
* LostInTranslation: The scene about [[spoiler: the deaths of Yukie and Yoichi may throw some people off if they're used to the month/day/year calendar system as opposed to the year/month/day system Japan uses.]]
* LoveMakesYouCrazy: Both Sora and Tsugumi get steadily more unstable in Sora's route resulting in [[spoiler:Tsugumi first half killing and then basically raping Takeshi (ot at least taking advantage of his confusion) on the gondola, followed by Sora having a minor FreakOut and trying to drown Takeshi with the sprinklers.]]
* LoveTriangle: Sora, Takeshi and Tsugumi. Obvious in both of his routes but only really problematic in Sora's [[spoiler:when both have mild breakdowns because of him, with Tsugumi apparently raping Takeshi on the Gondola after asking him to kill her and Sora's reaction of a mental breakdown through jealousy.]] The Kid as well, sort of, but his two choices aren't a BrokenBird with a SugarAndIcePersonality and a TinMan with [[WhatIsThisThingYouCallLove emotional expression issues]].
** Though one of them is [[spoiler:[[BrotherSisterIncest his sister]]]]. Good thing the other one is the "canonical"/True Ending love interest, huh?
*** All the {{UST}} between [[spoiler:Sara]] and the Kid admittedly does disappear instantly after that reveal. But there was more there than in any other route in the game which is mildly disturbing.
* LukeYouAreMyFather: [[spoiler:Hokuto and Sara are actually the son and daughter of Takeshi and Tsugumi, though in a slight subversion, Tsugumi already knew this.]]
* LyricalDissonance: Sara's ImageSong, "Lullaby of Tears", is a poppy, catchy, obnoxiously cute song about how alone and sad she is and how much she misses [[spoiler:her brother]].
* [[spoiler:MakingLoveInAllTheWrongPlaces: Takeshi and Tsugumi have sex in the Qualle (the jellyfish gondola) in Sora and Coco's routes, and in the IBF sickbay in Tsugumi and Coco's routes.]]
* [[spoiler:MamaBear: Tsugumi, as revealed in [[AudioAdaptation "After You've Gone"]]. Simply put, do ''not'' mess with Hokuto or Sara, or Tsugumi will kick your ass.]]
* MeaningfulEcho: In the prologue, You's line [[GratuitousEnglish "I am You"]] is said JustForPun. Next time, [[spoiler:it's said to You'haru by You'aki, to signify that they are [[CloningBlues the same person]].]] And in the epilogue, it's a CrowningMomentOfHeartwarming.
* MegaCorp: Leiblich Pharmaceuticals.
* MementoMacGuffin: Sara's pendant, which contains a hologram of [[spoiler:what she believes is]] her deceased father.
* MentalTimeTravel: The Kid wonders, in You's route, if his Déjà-Vus and amnesia are caused by this.
* MindScrewdriver: Coco's route manages to clear up virtually every mystery in the game.
* MoonLogicPuzzle: Without a walkthrough, some paths can be difficult to succeed on a first try. Most notably Tsugumi's good end.
* MoralityPet: Chami is this to Tsugumi.
** [[spoiler:MoralityChain: Hokuto and Sara were the only things that kept Tsugumi from becoming a NietzscheWannabe after Takeshi's death.]]
* [[spoiler:MorningSickness: This is how Tsugumi began to realize that she was pregnant. Particularly notable in her case, as she has the Cure virus, meaning she ''can't'' normally get sick, meaning something was clearly up.]]
* MrExposition: Sora generally fullfills this role inside [=LeMU=] [[spoiler:while You"haru" does so at the end of the game for Hokuto/Blickwinkel.]]
* MultipleEndings: An interesting subversion occurs here since the "True End" is actually much, much happier than the so-called "Good Ends".
* MurderTheHypotenuse: Subverted in [[spoiler:Sora's]] route: she decides to [[spoiler:try to kill Takeshi]] instead.
* NoNameGiven: [[spoiler: Tsugumi reveals that Hokuto's and Sara's names are their adopted names. It was never revealed what their true names are.]]
* NietzscheWannabe: Tsugumi, when at her {{wangst}}iest.
* NoExportForYou: You're from Europe? Tough luck.
* OfficialCouple: [[spoiler:Takeshi/Tsugumi, Hokuto/You.]]
* OlderThanTheyLook: Coco. Takeshi thinks to himself how energetic elementary school kids are these days... then is shocked to find out that Coco is a third-year in middle school.
** [[spoiler:Tsugumi as well. In 2034, all characters except Hokuto, Sara, You'aki and Sora are this. Coco looks 10 then although she's actually 32.]]
* OneDegreeOfSeparation: [[spoiler:Hokuto and Sara are Tsugumi and Takeshi's children. You'aki is You'haru's clone, and the elder's father helped design Sora and [=LeMu=] with Coco's father. You'aki and Hokuto are hooked up at the end. Coco has some sort of strange tie to Blickwinkel, and it's not entirely clear who or what that is. That leaves only Kaburaki as essentially having nothing to do with the rest.]]
* OneSteveLimit: [[spoiler:Subverted with Takeshi: he shares the same first name as Coco's father, Takeshi Yagami (although their names were spelled with different kanji in the Japanese version).]]
* OnlyKnownByTheirNickname: The Kid, by virtue of his amnesia, and You, whose full first name is ridiculously long [[spoiler:and full of spoilers. It's stated a few times, but deliberately never dwelled on for long. How long it is probably meant that [[ExactlyAsPlanned no one bothered to memorize it]]]].
* [[spoiler:ObfuscatingStupidity: Kaburaki in the 2034/Kid routes. It is not only ObfuscatingStupidity, but also Obfuscating Personality.]]
* OverlyLongName: That's why she wants to be called You instead.
* [[spoiler:OurHeroIsDead: Takeshi in both of his routes, of course.]]
* PairTheSpares: [[spoiler:Kaburaki and Sora]] in the Drama [=CDs=], rather awkwardly.
** [[spoiler:It probably would had [[FridgeLogic made a lot more sense]] to pair Kaburaki and You'haru together, considering that they spent 17 years together.]]
* ParentalAbandonment: You's father died in an accident when she was young, which lead her to work for [=LeMU=] to find out what happened to him. [[spoiler:He was blackmailed by Leiblich, who faked his death and forced him to continue working for them, and is found in IBF, where he dies of Tief Blau, but not before talking to You one last time.]]
** [[spoiler:Takeshi and Tsugumi also do this to Hokuto and Sara, though given their [[HeroicSacrifice diffe]][[HumanPopsicle rent]] [[DaddyHadAGoodReasonForAbandoningYou circumstances]], they can hardly be blamed. Not that Hokuto and Sara seem to mind...]]
* ThePlan / BatmanGambit: [[spoiler:The entire storyline is a massive trick, played by the player perspective, on himself.]]
* PlayfulHacker: Sara.
* ProperlyParanoid: Tsugumi. [[spoiler:Especially in 2034. At least in 2017 it really was an accident.]]
* [[spoiler:[[PsychicPowers Psyyyyychic Powers]]]: Coco claims to have this (spelled like that too), though the extent of her powers is vague. Her feats, however, include the ability to "borrow" the perspective of beings from "the other side" (the 4th dimension), enabling her to see the past, present, and future of everyone in [=LeMU=] (which would explain how she knows everything about what Blick Winkel eventually finds out). She's also able to project herself across time, allowing her to speak directly to Hokuto/Blick Winkel, in addition to actually being able to see the latter when they travel across time. [[ArsonMurderAndJaywalking Oh, and she can bend spoons with her mind.]]]]
** [[spoiler:The Drama CD "After You've Gone" takes Coco's telekinetic ability further, as she uses her powers to toss around a man who has restrained Tsugumi, while Coco herself is miles away at school. The feat left her mentally drained, however, and she ended up passing out on her desk as soon as she got back to class, but not before wishing Tsugumi good luck.]]
* PygmalionPlot: Takeshi and Sora, sort of.
** There's actually a scene with an extended bit of exposition specifically about the legend of Pygmalion as a thinly veiled allegory for the relationship between Takeshi and Sora. May bea LampshadeHanging, but probably is not.
* RapunzelHair: Tsugumi's hair extends to around her knees.
* ReallySevenHundredYearsOld: [[spoiler:Tsugumi, who stopped aging at seventeen due to her genetic code being rewritten by the Cure virus. By the end of the game, Takeshi, You'haru, Kaburaki and Coco have also become this.]]
* RedHerring: Several, but two notable ones only applies to Japanese players/those who played {{Never7}} first. [[spoiler:WordOfGod says that The Kid having the [[Creator/SoichiroHoshi same voice actor as Takeshi]] was meant to deceive players into thinking Kid was a clone of Takeshi (which was pulled off in {{Never7}}), and the Kid's premonitions and mentions of Cure was also meant to fool players into thinking he had Cure Syndrome.]]
* TheRemnant: Non-military example: [[spoiler:In "After You've Gone", Kleinmare, a branch of Leiblich, attempts to continue their activities by luring Tsugumi there, though it backfires in the end.]]
* RelationshipVoiceActor: Creator/KanaUeda, Creator/NorikoShitaya, and YuuAsakawa also played characters who were close to each other in some way in a [[FateStayNight certain other visual novel...]]
* [[spoiler:RipVanWinkle: Takeshi and Coco, who sleep for 17 years in cryo-sleep, though more the former than the latter (as Coco had access to Blick Winkel's viewpoint. In fact, the story of Rip Van Winkle is discussed by Takeshi, You, and Coco at one point as {{Foreshadowing}}.]]
* RobotGirl: Sora, although of a [[ProjectedMan Holographic AI Girl]]. [[spoiler:In the True End, she does get a robot body.]]
* SetRightWhatOnceWentWrong: [[spoiler:The whole goal of the BatmanGambit is to summon Blickwinkel to prevent Takeshi and Coco's deaths in the past.]]
* ShownTheirWork: The authors clearly knew their way around theoretical physics, as well as just what kind of circumstances would be required to operate an underwater theme park.
* ShoutOut: All of the names that the Kid can choose for himself are the names of protagonists from other KID visual novels, except for Prince (which is a ShoutOut to the KID game Prince Level 1):
** Tomoya Mikami -- Memories Off. Makoto Ishihara -- {{Never7}}. Naoto Miyama (mistranslated as Naoto Fukuyama) -- Yume no Tsubasa. Shiina Hasegawa -- Tentama. Motoki Homura (mistranslated as Motoki Inamura) -- Close to ~inori no oka~. Ken Inami -- Memories Off 2. Kyosuke Watarase -- My Merry May.
** In one of the paths, there'll be a party. You will perform an impression of a [[IndianaJones strange old archaeologist, who had a talent for cracking a whip]].
** There's a few other {{Shout Out}}s to {{Never7}}, including:
*** The scene where Coco is introduced as a third-year in middle school is close to Kurumi introducing herself as a third-year in high school. Both of them are YoungerThanTheyLook, and likewise act the same mentally.
*** The same argument over the name of the card game. Coco/Izumi call it "Super Memory," You/Kurumi call it "Mental Guts", Tsugumi/Makoto call it "Concentration", and Takeshi/Makoto settle for "Concenmemory".
*** [[spoiler:"A girl who doesn't have an older brother can call someone who's like a brother to her, 'Onii-chan'" -- a "made-up" rule stated by Coco near the end of the game, but one that Kurumi also abides to.]]
*** A scene with a sleeping male character (who is the only other guy in the group apart from the current protagonist), who mutters things in his sleep that change/randomize depending on how many routes have been cleared beforehand.
*** The entire epilogue, where [[spoiler:everyone is going home on a boat. Not necessarily BookEnds in Never7, but the idea seemed to be pulled from there.]]
* SignificantAnagram: LEMMIH spelled backwards is HIMMEL.
* SnowMeansDeath: Inverted, it's stated to have been snowing on the night [[spoiler:Tsugumi gave birth to Hokuto and Sara.]]
* SoapOperaDisease: [[spoiler:You'haru turns out to be suffering from a heart ailment that will take her life shortly, which is why she had herself cloned.]]
* [[spoiler:SomeoneToRememberHimBy: Shortly after Takeshi's death, Tsugumi learns that she's pregnant with his children, though he gets better in the True Ending.]]
* SpaceWhale: The "Cosmic Whale Room" has an animatronic one.
* SpitTake: Takeshi in Kid's routes, when he hears what You's high school club did.
* StableTimeLoop
* StepfordSmiler: [[spoiler:You, Coco, and Sara, though the last is a slight subversion as her GenkiGirl personality is actually genuine due to being free from Leiblich.]]
** [[spoiler:Coco is really only like this in a few scenes in her route, and Hokuto can see through it. Most of the time, she's genki to the extreme, and when she does get sad or depressed, she shows it.]]
* SugarAndIcePersonality: Tsugumi. When she's not being visibly disgusted with everyone (especially Takeshi), she'll prefer a cold emotional distance.
* TalkingToHimself: Takeshi and the Kid, which happens in the prologue [[spoiler:and the end of the game]], but is otherwise averted due to them having no voiced lines in their own routes. [[spoiler:The two Yous also go through this.]]
* TeamPet: Pipi the dog and Chami the hamster.
* TemporalParadox: ''Very'' unpleasant. see trope page for details.
* [[spoiler:TheAllConcealingI: Neither Takeshi nor the Kid's faces are shown when you play as them, not even in [=CGs=], but they are seen in the other's route. This is to hide the fact that [[TomatoInTheMirror the Kid is not the same Kid we see in Takeshi's route, and vice-versa]].]]
** [[spoiler:At the end of their routes, the game does slip up and show that their hair color is not as the player expects them to be, but most of the time, the attention is drawn to something else. See the TearJerker that is Tsugumi-Sora's bad end.]]
** [[spoiler:Averted on the one of the covers for the game, which blatantly shows Takeshi with bluish black hair.]]
* TheDogWasTheMastermind: [[spoiler:The one who came up with the plan is Blick Winkel (a sort of player avatar) with the goal of tricking himself and ultimately allowing Hokuto to call out 17 years into the past to his father. Basically, the player the mastermind behind the plans to trick himself.]]
** [[spoiler:Its hard to say who is the real mastermind though. Blick Winkel told You'haru the plan only because he knew about the plans from watching You'haru and Kaburaki carry it out in the year 2034. However, You'haru and Kaburaki only carried out the plans because they were told to do so by Blick Winkel. But Blink Winkel told them the plan only because he knew about the plan from watching... See the TemporalParadox here? No one will ever know who originally came up with the plan. Then again, if you studied real life TimeTravel philosophers, you might argue that [[StableTimeLoop the plan did not originate from anywhere, and it never needed to]].]]
* TheRashomon: Takeshi and the Kid both come off as being far more competent and ''interesting'' in their own routes. In Takeshi's routes, the Kid is a semi-stable, emotional kid who follows whatever the group says. In the Kid's routes, Takeshi is a huge ButtMonkey. [[spoiler:But it's a ''huge'' subversion because both of these are correct. 2017 Takeshi is much more confident and has stronger leadership qualities than 2034 Takeshi, who is a grown up version of the Kid from 2017.]]
* ThirdPersonPerson: Coco.
* TinMan: Sora.
* [[spoiler:TogetherInDeath: Sora's ending.]]
* TomatoInTheMirror: [[spoiler:When Hokuto/Blick Winkel discovers he's not the Kid from 2017.]]
* TrickedOutTime
* TrueCompanions: Takeshi gives a lecture to Tsugumi about the meaning of "nakama" (which is translated as "friend"), though she rejects the idea. [[spoiler:By the Epilogue, the 2017 and 2034 groups have essentially become one large group of TrueCompanions.]]
* {{Tsundere}}: Tsugumi by the end of her route, and the epilogue.
* UpdatedRerelease: The "Premium Edition", which contained about 15 new CGs (most of them related to Coco's Route), new sprites, and different bonus pictures. The CGs and sprites were also included in all PC versions of the game.
* {{Utsuge}}
* ValleyGirl: PlayedForLaughs- In Sora's Route, Sora asks Takeshi to teach her how to act more human-like. The ultimate result is that she begins speaking like the trope. However, after it ends up making Coco cry, Takeshi and Sora agree she should just talk like she normally does.
* VerbalTic: Sara, being a ninja fangirl, sometimes refers to herself as "[[JapanesePronouns sessha]]" and ends sentences with the archaic "de gozaru". The translation renders this as over-the-top flowery AntiquatedLinguistics.
* WalkingSpoiler: The Character Sheet has a separate folder for characters who fall under this trope.
* [[spoiler: WhatIfTheBabyIsLikeMe: Tsugumi is worried that her children might be Cure species, and won't be able to grow up like normal children. Luckily, her children end up as [[HalfHumanHybrid Sapiens/Cure hybrids]] who grow up normally, and are immune to the effects of the Cure virus.]]
* WhatYearIsThis: The Kid asks Takeshi this since he can't remember a thing. Takeshi seems to not know either and has to rely on his admission ticket. [[spoiler:Of course, when you're playing as the Kid, "Takeshi" (also known as the "original" Kid) lies to you, which is just the beginning of setting up the enormous MindScrew that is Ever17.]]
* WhatIsThisThingYouCallLove: Sora's route revolves around this.
* [[WritersCannotDoMath Translators Cannot Do Math]]: There are 17 meters between each level, but America doesn't really use the metric system. So they converted it to feet. The only problem is that there are about 3.3 feet in a meter and not just three. So not only do you lose another reference to 17, the conversions aren't done properly in some places.
* YamatoNadeshiko: Sora, {{Justified|Trope}} as that's her programming as a park employee AI. [[spoiler:However, it's subverted at one point in her route after she sees Takeshi and Tsugumi having sex, where she briefly goes {{Yandere}} out of confusion.]]
* YouAlreadyChangedThePast: Found out [[TemporalParadox the hard way]].
* YouGottaHaveBlueHair: Coco's is pink. Everyone else's is a reasonable color.
* YoungerThanTheyLook: Sora, who is 6. Justified in that she's an AI, and her age is given as eternally 24.

!! The Xbox 360 remake provides examples of:

* [[spoiler:AcheyScars: In the remake, Hokuto has a knife scar across his arm that Sara gave him during their {{Tykebomb}} training that Leiblich forced them through. Whenever he has a dream about his past or tries to remember it, the scar aches.]]
* BigBrotherMentor: Takeshi to the Kid. This was slightly present in the original, but really taken to its fullest in the remake.
* BittersweetEnding: The remake changes [[spoiler:Sora's Route]] from a DownerEnding to this. [[spoiler: While Takeshi and Sora still die, instead of futilely copy Sora onto a terabyte disk that won't make it out of LeMU, Takeshi instead uploads a program that makes a copy of Sora and wirelessly sends it to the successor LEMMIH computer, meaning that she'll still live on through that computer.]]
* ChekhovsGun: [[spoiler:A "Lemurian Tablet" is in the remake, a mysterious tablet supposedly from Lemuria that has strange hieroglyphics on it that no one can read, and has Coco's drawing on it. As it turns out, the Lemurian Tablet was created by Blick Winkel (via possession of another person from long ago), and the mysterious hieroglyphics have the details of Third Eye Project written on it.]]
* ChekhovsGunman: [[spoiler:Pipi, who is this version actually contains a quantum computer created by Yoichi Tanaka. When Sora's data is backed up, it backs up into Pipi, and Sora essentially becomes Pipi for the next 11 years until her android body is developed.]]
* EnhancedRemake: Contains an additional route [[spoiler:(the Blick Winkel Route, an epilogue of sorts that shows some of the events between 2017 and 2034)]], rewritten story (the main plot and major events are mostly the same, but a lot of the events in-between are completely different), complete background graphic, additional [=CGs=], character conversion from 2D to 3D, remixed soundtrack, and re-recorded voices.
* FixFic: [[spoiler:Essentially the second half of the Blick Winkel Route, where Blick Winkel uses his powers to fix the Bad Endings and give every route a happy ending.]]
* [[spoiler:LaserGuidedAmnesia: Kaburaki's amnesia, which was caused by an incident in 2029 where an experiment on space-time oscillation device designed to create an artificial black hole went wrong. Kaburaki had to manually shut it off, but the effects of the black hole briefly sent his 2029 self's consciousness to his 2017 self. The overload of memories caused 2017's Kaburaki's amnesia, but left him with a few fragments of 2029 Kaburaki's memories, which was the source of his "premonitions".]]
* [[spoiler:MemoryGambit: In this version, Hokuto was also one of the members of the Third Eye Project, due to his compatibility with Blick Winkel, and therefore had known he was going to lose his memory ahead of time.]]
* [[spoiler:PsychicPowers: In addition to Coco's from the original, it's revealed at the end of her route that Kaburaki is a low-level psychic. Furthermore, Professor Yagami in this version was actually researching these powers and their connection to the Third Eye.]]
* SchrodingersCast: [[spoiler:In the original, Professor Yagami's fate was never revealed, leaving it unknown what happened to him after Tief Blau broke out. Here, he managed to escape from [=LeMU=], made a miraculous recovery from TB, and became a major supporter of the Third Eye Project.]]
* StableTimeLoop: [[spoiler:A variation from the original- in the remake, Blick Winkel can only talk to other people when he's in possession of Takeshi or Hokuto (or if they have the Third Perspective, like the former two and Coco), and can't talk to anyone else. As a result, he can't directly tell You"haru" the Third Eye Project. As a result, he goes back in time and creates the "Lemurian Tablet", writing down all the details of the Third Eye Project.]]
* StepfordSmiler: [[spoiler:Sara, who was a subversion in the original, has it played straight in this version, though she still has moments of genuine happiness.]]
* [[spoiler:{{Tykebomb}}: In this version, Hokuto and Sara were trained to be agents of Leiblich, teaching them how to use weapons and various other things. However, Hokuto was removed from training when he was 11 after he protected Sara from a bomb she accidentally set off, injuring him badly. This allowed You"haru" to use her influence to get him out of there.]]
* VocalEvolution: [[spoiler:In the original game, Creator/SoichiroHoshi had two distinct voices: his "Takeshi" voice (which he uses for Takeshi and adult Kaburaki) and his "Kid" voice (which he uses for kid Kaburaki and Hokuto). By the Xbox 360 remake, he's developed a distinct voice for all four (his adult Kaburaki and Hokuto voices are similar to their original types, but slightly different).]]
