->''"I'm dreaming again...that summer day's dream."''

Full name - ''Noein: To Your Other Self'' (''Mou Hitori no Kimi e'')

Haruka is an average girl, living an average life. Or so she thinks. In fact, she is a CosmicKeystone being sought by the forces of two [[AlternateUniverse alternate dimensions]], La'Cryma and Shangri'La. Each represents a possible future for Haruka's world, and Haruka has the power to determine which one becomes reality. [[BadFuture La'Cryma]] is a shattered, dystopian place... but there is something sinister about the seemingly serene [[TheShangriLa Shangri'La]] as well. Which side should she choose?

Haruka and her friends find themselves in the middle of a war, with multiple factions and rapidly shifting allegiances. Some wish to protect her, while others will go to any length to abduct her. A few important characters include:

* '''Haruka''': Main character and MacGuffinGirl, despite those two usually being mutually exclusive.
* '''Yuu''': Haruka's troubled friend/love interest. EmoTeen extraordinare, complete with box cutter.
* '''Ai''': Haruka's best friend, she's the most HotBlooded of Haruka's friends.
* '''Isami''': Yuu's best friend, he has a fear of ghosts.
* '''Miho''': A close friend of Haruka's and TheDitz of the group.
* '''Karasu''': A FutureBadass version of Yuu from La'Cryma, sent to abduct Haruka but desiring to protect her.
* '''Fukurō''': Karasu's closest friend from La'Cryma.
* '''Atori''': An AxCrazy PsychoElectro rival of Karasu, also from La'Cryma.
* '''Noein''': The eponymous BigBad, mysterious [[MaskPower masked]] leader of Shangri'La.

The anime relies heavily on the ideas and theories present in quantum mechanics, most notably the idea that there are an infinite number of parallel universes, with [[WhatIf a new one created with every decision we make]]. At one point, it also references the paradox of SchrodingersCat. For added fun, watch it with someone who has [[TechnoBabble actually studied quantum physics]].

----
!!This program includes examples of:
* AmicableExes: Haruka's parents, although it took them a long time after a very bitter divorce to get to that point, and even in the present tempers can sometimes flare up. Despite this, near the end Haruka's father asks her mother to "bring Haruka to the park together, like old times," possibly implying an attempt to reconcile with her for good.
* ArtShift: An intentional example. Alternates per episode; only two animators, so only two styles.
* AfterTheEnd: La'Cryma.
* AlienBlood: The Dragon Knights bleed blue Layze/Reizu.
* AmbiguouslyBrown: Tobi.
* {{Amnesiac Dissonance}}: Atori.
* AnimeFirst
* AntagonistTitle
* ApocalypseMaiden: La'Cryma certainly think [[spoiler: Haruka]] is one.
* ArcWords: "I'm dreaming again...that summer day's dream," at the beginning of each preview.
** "Blue snow?"
* ArtificialLimbs: Kuina.
* AssimilationPlot: Shangri'La [[spoiler: is composed of all of the other realities that Noein wishes to prevent from happening. The inhabitants of Shangri'La are all humans whom Noein has absorbed into his cause]].
* BadassCape: The Dragon Knights.
* BadFuture: La'Cryma, but arguably Shangri'La as well. At one point Noein shows Haruka a bad future where each of her friends ends up [[BreakTheCutie getting broken]]. [[spoiler: Creepily enough, the specific injuries the other characters sustain imply that the timestream Noein shows to Haruka is Lacryma's past.]]
* BestOfAllPossibleWorlds: Deconstructed and back. Haruka has the ability to jump dimensions, and spends an episode or two observing possible parallel or future time lines. One is 'perfect' in a StepfordSmiler kind of way, one is seriously [[AfterTheEnd post-apocalyptic]], and most are pretty average, but after all of it she comes to decide there really isn't a best world, and even if there was, it's really not where she belongs.
* BigBad: The title Noein.
* BigFriendlyDog: Baron.
* BittersweetEnding: [[spoiler:Noein's plans have been thwarted, but Haruka has to say goodbye to the other-dimensional Karasu, and she will still likely face her untimely death a few years later in one way or the other]].
* BlandNameProduct
* BloodlessCarnage: Due to extensive bodily alterations, the Dragon Knights don't bleed actual blood when being wounded, which makes their fight scenes much less gory than they could have been.
* BloodyHandPrint: The last we see of [[spoiler:Haruka in Noein's past]].
* BodyHorror: The Dragon Knights' powers involve some very uncomfortable transformations of their physical selves. [[PsychoElectro Atori's]] power-up mode in particular is disturbing, given how [[AxCrazy unstable]] he is.
* CanNotSpitItOut: Yuu's feelings for Haruka, which Karasu encourages him to confess. Ditto for Ai and Isami.
* CastAsAMask: English dub only: [[spoiler: The title character is originally voiced by RichardEpcar, until his mask comes off, at which point he's voiced by Creator/CrispinFreeman, Karasu's voice actor.]]
* CatchPhrase: Isami thinks that it is impossible for him to have a catch phrase.
* CatFight: Haruka gets into one with Ai, who is jealous over what she believes to be a budding romantic relationship between Haruka and Isami, despite Haruka's attempts to explain. The audience knows from the get-go that it's not too serious, though, as it's accompanied by playful, cheerful background music (and they make up at the end of the episode).
** {{Lampshaded}} by a cut to a pair of lazy cats observing the proceedings.
* CharacterDevelopment: Yuu and Atori, and in varying doses the entire cast.
* ChekhovsGunman: Throughout the series, Uchida makes repeated attempts to get in touch with a "Dr. Mayuzumi", apparently one of the scientists in charge of overseeing the Magic Circle Project. [[spoiler: He turns out to be Haruka's father.]]
* {{Cloudcuckoolander}}: Miho.
* CombatTentacles: Karasu's wire-like attacks.
* ConspicuousCG
* CoolOldGuy: Kōriyama. Although some might call him sleazy rather than cool. And he's not that old.
* CorruptCorporateExecutive: Shinohara, the head of the Magic Circle Project.
* CrapsackWorld: La'Cryma and [[spoiler: Shangri-La]].
* CreepyCemetery: Both in Japanese and Western varieties.
* CynicismCatalyst: [[spoiler: Yuu's mother, Miyuki, was hit pretty hard by the death of her sister Emi when they were teenagers. It didn't help that their parents seemed to favor Emi for her better grades and achievements. This is the main reason she's pushing her son to get a good education.]]
** There's also [[spoiler:Karasu, who, while not necessarily cynical, is so hell-bent on protecting Haruka after seeing the Haruka from his own dimension willingly sacrifice herself to try to keep La'Cryma safe.]]
** And finally we have [[spoiler: Noein, who...[[OmnicidalManiac really didn't take it very well]] after the death of ''his'' own dimension's Haruka in a car crash.]]
* DamselInDistress: Haruka.
* DanBrowned: Quantum physics don't work this way. It's all for [[MST3KMantra the sake of the story]], though, so we forgive it.
* DeadPartner: Kōriyama's partner was murdered during a botched espionage mission several years before the events of the story. Due to the nature of the mission, it was covered up as a suicide.
* DesignatedLoveInterest: Yuu is a {{toy ship}} version of this to Haruka.
* {{Determinator}}: ''Karasu.'' He'll go through Hell and back twice to keep Haruka safe [[spoiler: because he feels [[MyGreatestFailure he failed to protect the Haruka of his own dimension]]]].
* DiabolusExMachina: The "future" shown to Haruka by Noein in episode 22, where she sees all of her friends' lives ruined. In quick summary,[[spoiler: Isami turns into a delinquent and loses his eye in a fight, Ai is told her leg must be amputated, effectively ruining her future of being an all-star soccer player, and Miho becomes a depressed {{Hikikomori}} due to bullying]]. The episode itself ends on a high note, though.
* DisneyDeath: [[spoiler: Yuu in episode 20, and Kōriyama in the final episode.]]
* DissonantSerenity: [[spoiler: When we finally see behind the mask, Noein manages to act in a manner that can be described as being filled with rage and depression, but he does it with a creepy smile and a calm voice.]]
* DrivesLikeCrazy: Miss Yukie, driving completely off the road. Justified in that she was trying to lose someone, but she was clearly enjoying herself.
* {{Dubtitle}}: In the UK release.
* DudeLooksLikeALady: Tobi.
* {{Dystopia}}
* EducationMama: Yuu's mother.
* EpiphanyTherapy: Yuu's mom gets over a life-long hang-up ''in just a day''. Possibly InVinoVeritas.
* EvilAlbino: [[spoiler:Noein]].
* EvilPhone: In one episode, after things start getting strange, Haruka asks her mother if she's ever encountered anything paranormal, and her mother mentions that her old house phone once rang, even though it was unplugged. At the end of the episode, the same unplugged phone rings again when Haruka's alone, so she picks it up, and realizes the person on the other side is her mother in the past. Haruka's mother is puzzled, while Haruka is very amused by the situation... and then her mother gets disconnected, and Haruka finds herself talking to ''[[MoodWhiplash herself from an alternate future.]]'' Her future self sounds so sad, and combined with the advice she offers, our Haruka is left quite shaken up by a vague hint at something ''terrible''.
* ExplosiveOverclocking: Dragon Knights can turn themselves into huge beings of energy, but it is very dangerous.
* ExpositoryHairstyleChange: After the AxCrazy Atori [[spoiler:loses all his memories and powers,]] his pointed bangs become rounded and curled up at the end. [[spoiler:It's reverted back by the final episode, though he never regains his sadistic tendencies.]]
* EyeScream: [[spoiler: Isami in the BadFuture of episode 22 loses an eye after being stabbed during a robbery. It's implied that this is where Fukuro's scar came from.]]
* TheFaceless: Future Haruka. [[spoiler:Except for the future in which she dies in a car accident]].
* FlashStep: The Dragon Knights use something similar to this.
* ForDoomTheBellTolls: Seen with [[spoiler:Fukuro's death]].
* ForeignQueasine: Although it's not technically foreign, and actually pretty tasty.
* FuroScene: Haruka gets several.
* FutureBadass: Karasu and Fukuro.
* FutureMeScaresMe: Yuu is scared by how cold and intense Karasu is. Karasu is disgusted by his cowardly former self. Furthermore, [[spoiler:Noein is yet another future version of Yuu, who despises both of them]].
** Karasu glaring at Yuu earned the honor of page picture for this trope for a very good reason.
* GasLeakCoverup: The first appearance of the Shangri'La attackers was explained to the public as a meteorological phenomena. Given their incredible obliviousness, probably it worked for the second time as well.
* GirlishPigtails: Miho. Haruka also wore her hair this way as a very young child.
* GoOutWithASmile: [[spoiler: The Haruka of Karasu's dimension.]]
** [[spoiler: Also, Tobi in the final episode.]]
* GoodSmokingEvilSmoking: Kōriyama and Shinohara, repectively.
* GreenEyedMonster: Yuu is jealous of Karasu because he takes up a lot of Haruka's attention.
* HackerCave: Tobi sets one up with some ExtremeGraphicalRepresentation thrown in for good measure.
* HairAntennae: Isuka.
* HairColors
* HairDecorations: Haruka's pink ribbon.
* HappierHomeMovie: One episode begins with Haruka watching a videotape of herself as a little girl, playing with her now-deceased grandmother.
* HarmfulToMinors: [[spoiler: Atori's backstory. As a child, he was from a war-torn country and watched his friend be blown apart after coming into contact with a landmine. According to him, this is also how his sister died.]]
* HeelFaceTurn: [[spoiler:Atori and Kosagi]].
* HeroicAlbino: Karasu.
* HeroicSacrifice: [[spoiler:Future Haruka]].
** [[spoiler: Also Atori, in the finale.]]
* HeyItsThatVoice: Creator/CrispinFreeman as Karasu and Creator/RichardEpcar as Kōriyama. We also have Creator/YuriLowenthal as Yuu - which makes his [[RelationShipVoiceActor entire relationship]] with Karasu rather amusing if you're a ''{{Naruto}}'' fan.
** Also Creator/KazuyaNakai in the original Japanese.
* HilariousOuttakes: Much to the English cast's surprise and glee many of their outtakes, ad-libs, and general screwing around was preserved on the official [=DVDs=].
* HornedHairdo: Lady Amamiku of La'Cryma [[spoiler: who is revealed to be that dimension's Ai. She lets her hair down again later, looking much more like her younger self afterward]].
* HotForTeacher: Isami shows shades of being attracted to Miss Yukie. It's PlayedForLaughs [[spoiler: and subverted when he seems to reciprocate Ai's feelings by the end of the series]].
* HotScientist: Uchida-chan.
* HugeSchoolgirl: Ai is shown towering over her female classmates while in high school.
* IgnoredExpert: Nobody listens to the warnings given by the experts on quantum physics, which include Uchida and Mayuzumi. The result is not pretty.
* IHaveTheHighGround: All of the Dragon Knights do this.
* ImCryingButIDontKnowWhy: Ai, after [[spoiler: Fukuro's death]].
* InterruptedSuicide: [[spoiler:Ai, in the alternative BadFuture shown by Noein. Isami arrives JustInTime.]]
** [[spoiler: BadFuture Miho attempts to overdose, but is stopped by Atori.]]
* JerkAss: Shinohara. [[spoiler: Not only does he shoot Kōriyama, he actually ''digs his foot'' into the wound [[KickThemWhileTheyAreDown while Kōriyama tries to get up.]]]]
* LightIsNotGood / DarkIsNotEvil: While [[FutureMeScaresMe Karasu]] slings dark lightning bolts around in their duel, AxCrazy Atori throws white lightning. Noein, similarly, decorates his realm like a Buddhist paradise and is clad in pure white.
* LimitedWardrobe: Considering the span of time the story encompasses, some characters change clothes very rarely.
** Haruka changes frequently but seems to have three outfits.
* LoveMakesYouEvil / LoveMakesYouCrazy: This has Noein written ''all'' over it.
* LookBothWays: A disoriented [[spoiler: and amnesiac]] Atori wanders into the road at one point, completely ignoring the truck headed straight for him. He's saved by Tobi at the last moment.
* MacGuffinGirl: Haruka, aka the Dragon Torque.
* MagicSkirt: Despite all the running, jumping and climbing Haruka does while wearing a very short skirt, the viewer never gets subjected to any {{panty shot}}s.
* MaskPower: Noein often appears as a floating mask.
* MeaningfulName: "Noein" is Greek (νοεῖν), which roughly translates to "I think/I know". More specifically, it refers to something that is known, but not through the traditional senses of the human body, only in thought. In other words, an existence defined solely by thought.
* MergedReality: Noein's goal.
* MyFutureSelfAndMe
* MoodWhiplash: There are a few, but [[spoiler: the car crash that killed Haruka and the others in Noein's timeline]] is exceptionally jarring. Probably because it was [[TruthInTelevision realistic]].
* MoralityPet: Miho turns into one for Atori.
* NighInvulnerability: Of a sort. For the Dragon Knights, thanks to mechanical replacements and the bizarre way they take damage, its as if they were made of a uniform shiny substance underneath their skin.
* OmnicidalManiac: Noein's ultimate plan for utopia is to erase the entire multiverse and start it again from scratch.
* OneWayTrip: The removal of the plugs connecting the Dragon Knights to their dimension.
* OpenMindedParent: While she's the kids' teacher rather than a legal guardian, Miss Yukie certainly fits the bill. When[[spoiler: Kurasu]] lies mortally injured after a battle with the forces of Shangri'La, she is completely unfazed by the fact that the person her students are helping is missing a limb, is bleeding blue sparkles and has no recognizable internal anatomy whatsoever.
* OuijaBoard: Paranormal-obsessed Miho suggests using one to figure out the weird stuff going on with Haruka early in the series. It spells "Noein", but at the time none of the characters present had ever heard the name, so they chalked it up to nonsense.
* {{Ouroboros}}: The motif appears with all the crazy quantum time wizzywigging. A giant one even serves as a portal to (effectively) TheLegionsOfHell.
* PantyShot: Averted, despite Haruka's penchant for wearing very short skirts.
* ParentalObliviousness: It takes the ''house disappearing'' before Haruka's mother realizes something strange might be going on.
* ParrotExposition: Kōriyama-san. Almost any scene with him talking to Uchida-san eventually descends into her effectively talking to herself.
* PeekABangs: Karasu. Sometimes Atori, too.
* PetTheDog: Haruka's dog, Baron, doesn't seem remotely intimidated by Karasu and allows the Dragon Knight to pet him. [[spoiler:Atori's treatment of Miho counts too.]]
* PinkySwear: Haruka remembers moving from Tokyo years ago, making one of these with her friend Aya to write to her every day. [[spoiler:She later runs into Aya in the present day, and is excited to see her again...until she learns Aya doesn't remember her.]]
* PowerBornOfMadness: Noein. [[spoiler:He was an {{ordinary high school student}} until a car crash killed his true love in front of him, after which it's suggested that his single-minded rage alone propelled him to gather followers, take over his Earth, master interdimensional travel and nearly succeed in obliterating everything in the multiverse.]] By contrast, [[spoiler:Karasu is a badass hero, but Uchida's technobabble baffles him.]]
* PowerTattoo: The Dragon Knights.
* PsychoElectro: Atori. [[spoiler:He seems to lose his sadistic tendencies after getting and recovering from amnesia, and [[HeelFaceTurn changing sides in the process]]. But then he gets [[CurbStompBattle left alone with the enemy]]...]]
* PunctuationShaker
* RazorFloss: This is Karasu's signature weapon. He can generate seemingly infinite amounts of it from his forearms.
* RealityWarper: Haruka.
** Noein has some elements of this as well. Unlike the Dragon Knights, whose bizarre powers are explained as being the result of Sufficiently Advanced Technology, Noein doesn't seem to use machinery at all, and can just ''do'' things. [[spoiler:He started off as an ordinary human. How did he become the dimension-hopping HumanoidAbomination he is now? No one knows.]]
* RealPlaceBackground: The series takes place in the Japanese town of Hakodate. There is a lot of emphasis on the spectacular view from Mt. Hakodate, and the ropeway to its summit plays an important role in one scene.
* RedemptionEqualsDeath: [[spoiler:Atori]].
* RedEyesTakeWarning: The moment we realize that ''that's not Karasu''.
* SayMyName: played rather masterfully in Episode 13 [[spoiler: when Karasu is mortally wounded]]
* SchrodingersCat: The Schrodinger's Cat scenario is actually an important plot point on two occasions.
** It's arguable that the entire plot can be boiled down to a schrodinger's cat. Yuu is indecisive about the future. Therefore, many possible futures exist. [[spoiler:When he takes control and decides what he's going to do, the path he did not choose disappears.]]
* SetRightWhatOnceWentWrong
* TheShangriLa: Shangri'La, obviously.
* ShesAManInJapan: Tobi was made female in the English dub, due to his feminine hairstyle and possibly as an effort to avoid implications of HoYay between him and Atori.
* SkintoneSclerae: Kōriyama looks like he has this.
* SignificantDoubleCasting: [[spoiler: Karasu and Noein, who are voiced by Creator/KazuyaNakai in the original Japanese, and turn out to be the same person from alternate timelines. The dub is bit different...]]
** CastAsAMask: [[spoiler: In the dub, Noein is initially voiced by RichardEpcar. When he's unmasked, he's instead voiced by Karasu's dub voice actor Creator/CrispinFreeman.]]
* SnowMeansDeath: [[spoiler: Subverted for the BadFuture of episode 22. While it's snowing when Ai makes her way to the hospital roof and Miho prepares to overdose, they're both interrupted.]]
* SoundtrackDissonance: The opening song at times seems unfit for the show.
** If you bought the DVD, you know they should have chosen one of those [[http://www.youtube.com/watch?v=i0e2-18xfpk alt openings]]!
** The song over the ending credits, too, could fall into this.
* TheSmurfettePrinciple: Kosagi. The English dub averts this with [[ShesAManInJapan Tobi]].
* StalkerWithACrush / {{Yandere}}: Kosagi followed Karasu to Haruka's dimension in order [[spoiler: to kill ''both'' of them, after realizing her feelings for Karasu were unrequited]].
* StrangeMindsThinkAlike: Everyone in the story. For some weird reason, they all instantly identify Layze particles (glowing blue sparks floating upside down in a small area) as blue snow.
* StrongFamilyResemblance: That little GenkiGirl with the pink hair and pigtails, running around La'Cryma? Yep, that's [[CloudCuckoolander Miho's]] daughter.
* TheStoic: Karasu, at least whenever Haruka ''isn't'' in danger...
* TechnoBabble: Uchida provides quite a lot of this, much to Kōriyama's annoyance.
* TechnoWizard / WrenchWench: Tobi falls somewhere between these two tropes.
* TheEndOfTheWorldAsWeKnowIt
* TheHeartless: The forces of Shangri'La are people who surrendered their humanity to go along with Noein's plans.
* TheMole: [[spoiler:Kuina]].
* ThemeNaming: The Dragon Knights are all named after birds; ''Karasu'' is the Japanese word for crow, for example.
** Also the names of two of the futures: Shangri-La is a fictional {{utopia}} in the novel ''Literature/LostHorizon'' (as well as a term for utopias in general). The lacrimal (La'Cryma) ducts are where tears come from.
*** Actually, "lacrima" means "tear" in Latin. Which is why it's ridiculous that even the official translation went with the nonsensical La'Cryma spelling as if it was just a random fantasy name. (Incidentally, this spelling for "lacrima" comes from the J-Rock band La'Cryma Christi).
* TheMultiverse: With each alternate reality being caused by a ForWantOfANail situation.
* TheOmniscientCouncilOfVagueness: One of these rules La'Cryma.
* ThePowerOfFriendship: One of the important points of the series.
* ThePowerOfLove: This is what ultimately allows [[spoiler:Karasu and Yuu to defeat Noein]].
* ThePresidentsDaughter: Haruka.
* ThemeTuneCameo: An instrumental version of "Idea" appears in the last episode.
* ThisIsUnforgivable: Said by a twelve year old girl. A twelve year old ''RealityWarper'', mind you.
* TimeStandsStill: Dragon Knights stop time before engaging in battle to make sure there are no bystanders.
* TimeTravel
* TitleDrop: During the first few episodes, each mention of Noein makes the viewer sit up and take notice.
* TomboyAndGirlyGirl: Ai and Haruka respectively.
* TouchedByVorlons: The Dragon Knights had their quantum structure changed in order to receive super powers.
* {{Tsundere}}: Ai for Isami.
* UnstoppableRage: Karasu, whenever Haruka is in danger.
* TheUnfavorite: [[spoiler: Part of the backstory of Yuu's mother. She felt her parents saw her this way compared to her older sister, Yuu's Aunt Emi.]]
* VariableTerminalVelocity: Haruka is able to catch Yuu by jumping off a cliff after him.
* ViewersAreGeniuses: You can understand quantum mechanics, right? Good. (or maybe not so good, considering the research slip-ups.)
* VillainousValor: Atori is at first unlikable, yet eventually his steadfast determination turns out to be quite an admirable trait. [[spoiler: Even if you don't consider him a villain at the end, the trope still rings true in retrospect.]]
* VisitByDivorcedDad: Haruka has a "date" with her dad once every three months, and they still get on well.
* TheWatson: Kyoji's primary purpose is to have Ryoko explain quantum mechanics to him.
* WeHardlyKnewYe: Isuka.
* WellIntentionedExtremist: Noein.
* WoobieDestroyerOfWorlds: Noein.
* YouShallNotPass: [[spoiler:Atori]], in a CrowningMomentOfAwesome.
