->''"If there's anything you want, anything at all... come to me. I'll be your guardian angel."''
-->-- '''Opening Theme'''[[note]]the line itself is taken from the film ''The Swimmer'', starring Burt Lancaster[[/note]]

In the not-too-distant future, deep underground, descendants of a banished generation vie for control of the crumbling city of Lux. Ichise, an orphan turned prize fighter, loses an arm and a leg to satisfy an enraged promoter. On the brink of death, he is taken in by a young female doctor and used as a guinea pig for the next evolution of [[ArtificialLimbs texhnolyze]].

Having adjusted to his new limbs, Ichise is eventually taken under the wing of Onishi, the powerful but distrusted leader of Organo, a criminal organization with some hold over the people of Lux. Meanwhile, four different factions begin to draw battlelines for territorial control of the city: the aforementioned Organo; the Union, a fiercely anti-texhnolyze faction; the Racan, a group of rebellious texhnolyzed youths; and the Class, a mysterious group of privileged beings who lurk behind the city. As Ichise is unwillingly drawn deeper into an uncontrollable war, he learns of his possible future from the prophet girl Ran, who guides him from the shadows in his darkest times. When society comes crashing down, Ichise must uncover the truth about Lux and fight for his survival.

Made by the same team that produced ''Anime/SerialExperimentsLain'', ''Texhnolyze'' is often considered to be one of the strangest and darkest anime ever made.

----
!!''Texhnolyze'' provides examples of:

* AffablyEvil: [[spoiler: Yoshii]].
* AGlassOfChianti: Doc can frequently be seen drinking red wine, from a lab beaker no less.
* ApocalypseHow: It is vaguely presented, but the implications are that [[spoiler:the surface-dwellers of the world at least partially predicted the decline of the human species, and isolated those with greatest genetic chances of prospering, which just happen also to be those that create violent tendencies. Also isolated were predecessors of the members of the Class, who were given special privileges in Lux in return for their cooperation. It is arguable as to whether this was a better decision than their first choice to solve the problem: kill everyone.]]
* AppliedPhlebotinum: Raffia, which allows the ArtificialLimbs to be attached to a human body.
* AfterTheEnd
* AllThereInTheManual: Given the minimalist tone of the series, several characters barely speak and have unspoken names which only appear in the credits.
* TheAloner: Ichise. {{Lampshaded}} by various people in-series.
* AmbiguouslyGay: Toyama.
* AndIMustScream: [[spoiler:This is how the Shapes end up]].
* AnimalTesting: Doc does this on rats, as is typical of an experimenting scientist.
* ArtificialLimbs: The texhnolyze technology applied to humans, mainly in Ichise and Onishi's case but also [[spoiler: Kano]]. Later events take this trope to a very disturbing extreme [[spoiler: with the Shapes, humans who discard their biological bodies to be almost fully automatized as mechanical beings]].
* [[spoiler: TheBadGuyWins: Both Yoshii and Kano ultimately get what they want, in spite of the fact that they both die in the process.]]
* {{Badass}}: Several, the most frequent ones being Ichise, Onishi, Shinji, Kimata and Toyama.
** BadassInANiceSuit: Onishi. He's pissed when his nice suit gets damaged.
--> I just had it serviced.
* BackToBackBadasses: [[spoiler: In episode 17, Onishi and Kimata, leaders of opposing organizations who would like nothing more than to tear out each others' throats, commit to this as the Organo aids the Union in fending off the Shapes.]]
* [[BlackAndGreyMorality Black And Very Dark Grey Morality]]: Even the most sympathetic characters in Lux skirt close to being [[VillainProtagonist Villain Protagonists]] at times.
* BladeBelowTheShoulder: Part of Yoshii's [[spoiler:prosthetic arm, unfortunately for Onishi]]. Also [[RetractableWeapon retractable]].
** The Shapes also use these to devastating effect.
* BigBad: [[spoiler:Yoshii]] in the first half of the series, [[spoiler:Kano]] in the second.
* {{Bishounen}}: Toyama is a less-traditional version.
* BloodSport: The almost ritualized 'spectacles' that take place in Lux at first glance seem to be nothing more than ways for the citizens of Lux to release their savagery [[spoiler:but there are prominent clues that the spectacles happen to procure bodies for [[HumanResources Raffia]], which just adds to the [[CrapsackWorld brutality of the setting]]...]]
** The boxing matches that Ichise participated in before becoming texhnolyzed did't involve gloves or protection of any kind.
* BodyHorror: All over the place. Texhnolyzation itself is seen as such by several characters. Then there are [[spoiler:the Shapes, and what happens to Ran.]]
* BondVillainStupidity The villains frequently keep blathering while they have one of the protagonists at their mercy.
** Justified in Kano's case. [[spoiler:When confronted by Ichise, he is physically helpless, and only has his words to defend himself.]] And of course both he and Yoshii really want to be believed and understood by others, and genuinely try to appeal to people with their rants.
* BoomerangBigot: Kimata, the leader of the Union, hates texhnolyze despite being texhnolyzed himself. Towards the end of the series his [[TheDragon dragon]] calls him out on it [[spoiler: only to reveal himself as a far worse hypocrite by defecting to the Class and becoming a Shape]].
* TheCaligula: Kano.
* TheChessmaster: Kano, again. He isn't even revealed until after most of the damage has been done.
* ChickMagnet: Ichise. Every woman he comes across seems to want a piece of him. It's more disturbing than anything, especially considering his reactions to them.
* CicadianRhythm: On the surface, which makes the feeling of desolation even more pronounced.
* CityNoir: With [[DutchAngle Dutch Angles]] to boot.
* CoolBike: Racan members tend to use these as their main methods of transport, as opposed to the large trucks employed by the Union and the more stylish Mafia cars used by the Organo.
* ConspicuousCG: When showing Ichise's texhnolyze arm and leg before they've been attached, as well as the [[FanNickname Discoball of Doom]].
* CrapsackWorld: Lux is presented as the dumping site of the planet. [[spoiler: However, the surface world is revealed to be almost completely depopulated, save for "ghosts" of people, because humanity has lost the collective will to live]].
* CreepyMonotone: Kano's voice always stays flat and emotionless, which just adds to his creepy nature. Yoshii is much the same, maintaining a pleasant falsetto tone to his voice.
* [[CreepyTwins Creepy Triplets]]: Kano's mothers. Especially when they [[PsychoticSmirk smile]] in unison.
* CrowdChant: The Union's "SOUL! BODY! TRUTH! SALVATION! VENGEANCE!" counts.
* CyberCyclops: The Shapes' helmets.
* CyberneticsEatYourSoul: The Salvation Union are especially zealous about this.
* CyberPunk: Like ''Anime/SerialExperimentsLain'', ''Texhnolyze'' is a particularly dark example.
* CyberPunkWithAChanceOfRain: Kicks in especially later in the series, disregarding actual rain obviously.
* DecapitationPresentation: [[spoiler:Kano]] does this in a slightly less traditional way with [[spoiler:Ran]], [[spoiler:and she's [[FateWorseThanDeath still alive]].]].
* DeathRay: The Shapes carry these, capable of shooting a perfectly circular hole through anything.
* DespairEventHorizon: The series ''starts'' here and gets worse. The city of Lux is full of people despairing with their lives to the point where some just sit on the street too depressed to move, and Ichise comes from a childhood of despair. [[spoiler:Yoshii was driven to insanity through his despair and dissatisfaction with the surface world, Tetsuya ''lives'' on the horizon, Shinji passes it when he goes on his KillEmAll rampage up on the Hill, and Doc passes it when she discovers what the surface world consists of. Fitting, given that the rest of the surface-dwellers of the Earth passed it a long time ago.]]
* {{Determinator}}: Ichise proves immovably determined to stay alive time and time again. Even Doc and Onishi remark on this, the first with amusement, the second with irritation because Ichise refuses to die in the first couple of episodes when he really should have.
* DissonantSerenity: One of the more terrifying things about [[spoiler: Yoshii]] as well as Kano.
* DoesThisRemindYouOfAnything: All over the place, thanks to a heavy reliance on symbolism and metaphor to convey the story.
* DontYouDarePityMe: Shinji.
* DoubleStandardRapeFemaleOnMale: There are several instances in which Doc has sex with Ichise while he's not in a position to give or withhold consent. Despite this, she's still portrayed as mostly benevolent ([[BlackAndGreyMorality by the show's standards, anyway]]).
* [[spoiler: DownerEnding: While maintaining an extremely dark and depressing atmosphere throughout the show, the ending still manages to be impressively sad.]]
* DrivenToMadness: In perhaps the most ambitious example of this trope, [[spoiler: Kano drives the entire city of Lux to madness, reflecting the inner state of his mind]]. {{Lampshaded}} by Ran, Onishi, and Kano.
* DrivenToSuicide: [[spoiler:It is implied that Doc committed suicide in the bathtub of their hotel suite after Ichise went back to Lux. Also Ran, who killed her own mind to spite Kano and escape from an AndIMustScream situation]].
* [[spoiler: DyingAlone: Ichise inadvertently fulfils Ran's prophecy of him. However, as the power of his texhnolyzed limbs almost dissipates completely, his arm projects an image of a flower onto the ground.]]
* DysfunctionJunction: Literally ''everyone''.
* {{Dystopia}}

* EnemyMine: Onishi tries to negotiate this with the Racan and the Salvation Union in the beginning of the series when he suspects that somebody's attempting to break the incredibly fragile peace in Lux.
** [[spoiler: Onishi and the Organo assist Kimata and the Union when they attempt to rally against the Shapes. It doesn't end very well for the Union and Onishi's forced to retreat.]]
* ExtremeDoormat: Ichise seems to have this attitude a lot of the time, though he does lash out every so often.
* EyeScream: Ichise gets his pupil plugged by the fingernail of his promoter's girlfriend during sex, which earns her a punch in the face. [[spoiler:Hal also suffers one of these when he betrays Shinji and then returns to kill him as a Shape. You don't see the actual injury, but the crunching sound is enough.]]
* FallenPrincess: Doc was initially a member of the Class, but is banished for vague reasons.
* FalseUtopia: The surface world.
* FanDisservice: Ichise's shirtless scenes and Doc's fetish of sleeping with her patients would provide relief from the impending grimness of the show if it wasn't for the disturbing manner in which they are presented.
* FateWorseThanDeath: [[spoiler: The Shapes, left immobile and immortal, and Tatsuya, who is left to wait until he dies in silent misery on the surface.]]
* FingerPokeOfDoom: [[spoiler: Shinji to Hal when the latter becomes a Shape and attacks him.]]
* ForTheEvulz: This is what makes [[spoiler:Yoshii's]] reign of terror all the more horrifying: his utter lack of a motive for it. It's made even worse by his placid and rational demeanour throughout the whole event and gets down right chilling when we see through Sakimura that he was once just an innocent, optimistic office drone.
* FoodPorn: Inverted. The only appetizing food shown is that eaten by privileged inhabitants of Lux like Doc and Onishi. Everybody else's is unappetizing goo.
* FromBadToWorse: In general, the longer the show goes on, the more hopeless its characters' situations start to look. [[spoiler: And then you find out what's [[DespairEventHorizon above-ground]].]]
* FromNobodyToNightmare: [[spoiler:Yoshii]] arrives in Lux halfway through his transition and its only through flashbacks that we learn just how much of a nobody he was before he damn near destroyed the city.
* GenreSavvy: Shinji.
* GoOutWithASmile: [[spoiler: Ichise in a particularly tragic example in the final episode, and it's the only time he ever does really smile...]]
** Also, [[spoiler: Toyama]]
** [[spoiler:Onishi smiles before the Obelisk just before he's gunned down by the crazed Luxites.]]
* GirlishPigtails: Ran.
* HatesBeingTouched: Ichise. Even the few times he's shown having sex, he just lies there with the woman sitting on top of him.
* HeroesFightBarehanded: Ichise, mainly because he's a prize fighter. He does get a sword later on.
* HeroicMime: Ichise can talk, he just stubbornly prefers not to.
** The [[HilariousOuttakes Gag Reel]] {{Lampshade}}s this by taking advantage of FilmingForEasyDub and having him talk non-stop.
* HeyItsThatVoice: Most notably, Doc is [[Manga/{{Hellsing}} Sir Integra Wingates Hellsing]].
** [[SamRiegel Yoshii]] is [[Anime/CodeGeass Clovis]], [[Anime/TengenToppaGurrenLagann Viral]], and [[Anime/ParanoiaAgent Li'l Slugger]], [[WendeeLee that prostitute he talks to]] is [[Manga/{{Akira}} Kei]] and [[Anime/CowboyBebop Faye Valentine]], and [[Creator/MichaelMcConnohie the head of the Union]] is [[Anime/CodeGeass Emperor Charles]]. [[Creator/CarrieSavage Ran]] is [[Anime/HaibaneRenmei Rakka]], [[Manga/IkkiTousen Hakufu Sonsaku]]. and [[Anime/StellviaOfTheUniverse Shima Katase.]]
* HiddenVillain: It takes a while before [[spoiler: Yoshii]] is revealed as the BigBad of the first story arc. Especially since [[TheYakuza Onishi]], [[GangBangers Shinji]] and [[ChurchMilitant Kimata]] all seem candidates as well.
* HighPressureBlood: Whenever there is a massacre, and there are quite a few.
** [[spoiler: Toyama's death, complete with CleanCut and HighPressureBlood.]]
* HilariousOuttakes: The DVD releases feature "Alternate Dialogue Outtakes", which redub select clips from the included episodes with snarky, filthy, or outright bizarre dialogue (such as changing a vicious gun battle into a rather enthusiastic paintball match, and by-and-large {{lampshading}} the entire [[{{Bowdlerise}} bowdlerization process]]).
* [[spoiler: HumanResources: Raffia. Even more terrible when it's revealed that it actually no longer serves a purpose and is simply being produced as a matter of procedure]].
* HeadsUpDisplay: For texhnolyzed people through their corneas, complete with bubbling gurgly noises.
* HumanityIsInsane: Kano seems to believe this. [[spoiler: Within the context of the show, he is arguably right.]]
* HumanitysWake
* HumansAreBastards: Seems to be the closest thing the show has to an overarching message.
* ILied: [[spoiler: Doc reveals that she never used the (dead) cells of Ichise's mother to power his arm--it was just so she could get him to accept the texhnolyzation. Ichise is far from amused.]]
* {{Industrial}}: It is CyberPunk after all. Some prominent examples include the Juno Reactor ThemeSong "Guardian Angel (Xavier's Edit)" and "A Dog's Heart Leaping from Irritation".
* InnocentFlowerGirl: Ran plays with the trope in various ways, though she really isn't all that innocent.
* IRejectYourReality: [[spoiler:Kano is a delusional solipsist with severe homicidal tendencies who won't entertain the idea that human beings are anything other than playthings produced by his mind]].
* ItsAllAboutMe: Kano, in one of the most horrifying examples of this trope. [[spoiler: He believes that Lux itself is a reflection of his mind, and that humans are puppets or homunculi eroding it. He would qualify for AGodAmI, except that he doesn't believe that he's God, he believes that he is ''reality itself''.]]
* JigsawPuzzlePlot: The workings of the Raffia, the Organo, the Class and surface are all explained through minimalist storytelling. Pay attention.
* KarmaHoudini: Arguably, [[spoiler: Yoshii]], to the extent someone can be in this show. [[spoiler: While he does get killed, his death is a lot less gruesome and painful than those which befall pretty much every other character.]]
* KatanasAreJustBetter: Subverted at times but also played straight many a time. Some of the curved blades used by the Organo thugs seem to be cavalry sabers rather than katanas, but the main characters in Organo all use katanas, so this trope is played straight more often than not.
** KukrisAreKool: Hal uses one.
* [[spoiler: KillEmAll: By the end of the series, absolutely everybody is dead, with the exception of the Shapes, who are forced to live forever, and Tetsuya, who is still waiting to die on the surface.]]
* KnightOfCerebus: Kano.
* LackOfEmpathy: Yoshii.
* LastStand: [[spoiler: The final episode tells us exactly what happened in Lux while Ichise and Doc were investigating and warning the surface, in a vignette-like film-grainy fashion. Onishi, Shinji and what's left of Lux (including the Seer's followers) band together to try to prevent Ran from being taken by Kano and the Shapes, since she's the only person left to protect. [[HopeSpot Not surprisingly]], [[DespairEventHorizon it fails]], and all the people of Lux lose the will to do anything once Ran is taken.]]
* LikesOlderWomen: Yoshii is only interested in prostitutes with "experience."
* [[spoiler: LittleDeadRidingHood: Ran]].
* LonelyPianoPiece: [[http://www.youtube.com/watch?v=FMH6Ru7bBKI "Time for Blooming Flower"]].
* LostTechnology: Interestingly enough, the surface world seems to be stylistically stuck in the fifties, with old fashioned radios and other outdated technology just laying around, but mixed with various examples of extremely sophisticated tech.
* MadOracle: Although Ran claims to be this at the end, she in fact [[CrazySane narrowly subverts this trope]].
* MadScientist[=/=]HotScientist: Doc, in equal parts.
* ManipulativeBastard: Several; most prevalent are Yoshii and Kano. A couple of the Organo take a stab at it, but fail when they are thwarted by other, smarter [[ManipulativeBastard Manipulative Bastards]] such as Kohakura and Onishi. And while not really being one himself, Shinji seems rather adept at seeing through other people's machinations when inclined.
* MeaningfulName: Lux, or "Ru9su" as it was originally called. Kohakura makes a remark about this.
-->'''Kohakura''': [[spoiler: He said this is the Ninth Annex of the Reviving Hell.]]
* MechaMooks: Subverted by the Shapes.
* MercyKill: [[spoiler: Ichise does this for Ran at the end]].
** Onishi [[spoiler:does this for his secretary when she begs for it]].
* MessianicArchetype: Ran.
* {{Minimalism}}: The series' defining stylistic trope.
* MindScrew: This series can be difficult to understand given the method of storytelling.
* MobWar: This is the focus of the first half of the series, instigated by [[spoiler: Yoshii]].
* MuggingTheMonster: Two Racan thugs try to mug [[spoiler: Yoshii]].
* {{Mukokuseki}}: Averted, by and large. It's possible to infer the entire cast's ethnic backgrounds just by looking at them, the only aberration of course being Kano, who was specifically designed to look as alien and "anime" as possible in order to sell just how much of an OutsideContextVillain he really was to Lux.
* MyNewGiftIsLame: Kano has a more petulant version of this in his backstory, just to show off what an irredeemable monster he is: Onishi [[spoiler:sold his legs to the Class in exchange for what amounted to starter money to work his way in to the Organo (hence why he has texhnolyze legs). Kano received the legs as a gift and either got bored of them or found some other reason to be rid of them, effectively squandering Onishi's sacrifice]]. And of course, he [[EvilGloating gloats to Onishi about it]] when they meet face to face.
* MysteriousWaif: Ran, especially before she becomes a viewpoint character.
* NightmareFuelStationAttendant: Kano.
* NothingIsScarier: When the characters reach the surface world.
* NoHoldsBarredBeatdown: Ichise does this to... a lot of people.
* NoPronunciationGuide: Despite being spelled "texhnolyze" it's pronounced "technolize", with the "xh" forming a the harsh "eck" sound normally heard in the word "tech".
* NotWorthKilling: [[spoiler: Hal]] after his FaceHeelTurn says this to Shinji. He apparently changes his mind shortly afterward.
* OedipusComplex: Ichise, who never really knew his father, adopts Doc as his "second mother" by WordOfGod. However, he lets her have sex with him whenever she repairs his texhnolyzed limbs.
* OneHitKill: Ichise basically [[CrowningMomentofAwesome does this]] to [[spoiler: Yoshii]], who had just recently taken down [[spoiler: Onishi]] and effortlessly killed many Organo members. He [[SingleStrokeBattle does it again to]] [[spoiler:Toyama]] near the ends of the series and then makes it a hat-trick by [[spoiler:punching Kano's head off its shoulders]].
* OnlySaneMan: Onishi, though Kano believes it of himself.
* OracularUrchin: Ran, yet again.
* OutsideContextVillain: [[spoiler:Kano. Lux might have been able to bounce back from Yoshii's reign of terror, but it was doomed the moment the Shapes arrived from the Hill. Kano steamrolls over everyone and despite Onishi's efforts to mount a counterattack Kano damn near wins before his self-destructive nihilism (and Ichise's fist) catches up with him]].
* ParentalIncest: [[spoiler:Poor Toyama]]. Apparently also how [[spoiler: Kano]] came into this world.
* PinballProtagonist: Ichise.
* PlatonicProstitution: Yoshii rents a room with a prostitute [[FanDisservice who turns out to be severely mutilated]], but only to get information about the city. Later he does sleep with her [[spoiler: and finally kills her and her pimp]].
* PrimalStance: Ichise takes this when walking out of an Organo cell block daring anybody to try and stop him.
* PsychoForHire: [[spoiler: Yoshi, made scariest by his overall sane-looking attitude and soft voice.]]
* PsychopathicManchild: Kano is a Type C.
* PygmalionPlot: One of the sideplots between Doc and Ichise.
* RapeAsBackstory: [[spoiler: Toyama]]. He really hates his father.
* RapeAsDrama: [[spoiler: Onishi's secretary Michiko]], by the end of the series, has been raped and abused so much by a trio of remaining Luxites that she's barely responsive and only asks to be killed.
* RoaringRampageOfRevenge: [[spoiler: Ichise to the man who sold his father out and had him killed. It gets him in trouble.]]
** [[spoiler: What Ichise does to the crazed people of Lux after they kill Onishi at the Obelisk.]]
** Also counts when [[spoiler: Ichise '''punches''' off Kano's head for what he's done to Ran.]]
* RoyallyScrewedUp: Kano, a high ranking member of the Darwinistic nihilistic Class.
* SceneryGorn
* SchizoTech: The setting combines advanced ArtificialLimbs and other futuristic technology with early 20th century phones, cars, trains and weapons. The Class, on the other hand, is so technologically advanced it's lead to a form of transhumanist inbreeding. See Kano and his retinue of BodyHorror technofreaks. The surface world is shown to be both highly advanced (see Yoshii and Sakimura's office) and has apparently regressed back into the 1920s.
* ScrewDestiny: Ichise's approach to Ran's prophecy. [[spoiler:It doesn't work.]]
* SelfDestructiveCharge and FoeTossingCharge: [[spoiler:Kimata]] does this near the end of the series against the Shapes with the Union behind him. [[spoiler: It [[CurbStompBattle fails horrifically in the end]], resulting in [[GoryDiscretionShot his]] and the rest of his organization's deaths]].
* SexlessMarriage: One scene shows that Onishi and his wife sleep in separate beds. Which would explain why Onishi sleeps with his secretary instead.
* SexySecretary: Michiko, Onishi's secretary. On her day off she gets flirted with by Shinji too.
* SheathStrike: [[BadAss Onishi]] uses his sheathed sword to beat the crap out of Union and Racan thugs alike when he's caught alone amidst their street scuffle.
* ShirtlessScene: The anime begins with a naked Ichise staring at himself in the mirror. Keeping up with the spirit of the series, it is not used as {{Fanservice}}.
* ShoutOut: To ''Theatre/{{Macbeth}}'' in episode 18. Also, scenes from the surface world mimic the paintings of Edward Hopper.
* ShutUpHannibal: Ichise sharply disagrees with Kano's nihilism. [[spoiler: This is expressed by punching Kano's head clean off.]]
* SilenceIsGolden: The first line of dialogue isn't spoken until 11 minutes into episode 1. Ichise, the ''protagonist'' of the series, doesn't say anything until episode 3, and after that is [[HeroicMime practically mute]] unless spoken to by someone he respects like Doc, Onishi, Toyama, or Ran.
* SissyVillain: Kano doesn't do any fighting, unlike Yoshii.
* SlidingScaleOfFreeWillVersusFate: Skates between type 0 and type 1. Ran predicts the future, but it is just one of many possible futures... unfortunately, if it is a long-term prediction it is almost always correct. It's not that there is a higher power, it's just that the inevitable succession of human actions leads to the result she predicts.
* SlidingScaleOfIdealismVersusCynicism: They don't get much more cynical than this show.
* SlidingScaleOfSillinessVersusSeriousness: Or serious for that matter.
* SmugSnake: Mizuno, to the point where both the Union and the Rakan hang a lampshade on him in very short succession. Kohakura seems like a more competent example [[spoiler:but then arguably ends up [[FateWorseThanDeath even]] [[AndIMustScream worse]]]].
* SupernaturalGoldEyes: Ran the prophet. Kano, however, averts it by being crazy but human.
* SurprisinglyGoodEnglish: The second ED that plays after the final episode, "Walking this Empty Earth", features English lyrics and, while they are heavily accented and rather nonsensical, the grammar is correct and understandable.
* TheStarsAreGoingOut: Near the end of the series the artificial sky above Lux finally craps out, [[AlwaysNight turning cement gray and plunging the city into an unending night]].
* TheStoic: Ichise, who only speaks when he has to. His first lines aren't until the third episode.
* StormingTheCastle: Shinji, in the second-to-last episode.
* StoryArc: Two of them; the first half mainly revolves around the actions of Yoshii, the second half is about the war for the city and Kano.
* SwissArmyAppendage: [[spoiler: Yoshii's prosthetic arm doubles as a retractable arm-blade]].
* TallDarkAndHandsome: Ichise is a sort of diamond-in-the-rough version, until he puts a suit on that is.
* TechnologyPorn
* ThatManIsDead: Ichise says this when talking about his missing limbs.
* ThereAreNoGoodExecutives: A rare subversion in [[spoiler:Onishi]], who is distrusted as the head of the ominous mafia-like business, Organo, that maintains enough control over Lux to prevent it from falling apart; despite this, he is one of the show's few sympathetically heroic characters.
* ThrowingYourSwordAlwaysWorks: Well, it does when you have a computer in your arm plotting out the trajectory for you.
** Hal does this with his [[KukrisAreKool own weapon]] to help out Shinji during the bloody scuffle between Racan and the Salvation Union.
* {{Transhuman}}: The entire show is one long pessimistic study of transhumanism. It's conclusion? [[HumansAreBastards People are fucked up]], and [[TranshumanTreachery transhuman people are even more fucked up than regular people]].
* TheUbermensch: Kano, who leans very much towards SocialDarwinist tendencies.
* UndyingLoyalty: [[SexySecretary Michiko]] to Onishi.
* TheUnfettered: Both Yoshii and Kano, and Ichise before he meets Ran.
* VisionaryVillain: [[spoiler: Kano, though it's a vision of basically nothingness]].
* WhatMeasureIsANonCute: There are big brown rats everywhere, they are particularly noticeable when Ichise gets thrown into the sewers, and they are Doc's test subjects, but they are not depicted as hostile; in most cases, they are presented as pitiful creatures.
* WildCard: Ichise and Yoshii.
* WorldHalfEmpty: Few anime have ever been so faithful to this trope. [[spoiler:Not only does Lux itself qualify, but we later learn that the world on the surface is nearly empty, being only populated by ghostly half-humans that have given up on living but are too tired to seek death]].
* WretchedHive: Lux, obviously. This was inevitable due to the nature of its creation.
* WorldOfSilence: [[spoiler:The surface world, and Lux after the Shapes stop moving.]]
* XtremeKoolLetterz: That X in the title may lead the uninitiated to pronouncing the title "Teks-nolyze". The anime itself makes it quite clear this is not the case.
* YouCantFightFate: [[spoiler: Ran prophesies that Ichise will kill countless people before dying alone and unloved. He swears to fight this fate. He doesn't succeed.]]
* YouGottaHaveBlueHair: Everyone else in the series has realistic hair and eye colors except for Kano, who has blue hair and yellow eyes.
* ZergRush: Seems to be the method of the Racan due to their disorganization, and is later employed against the Shapes by nearly all of the factions to varying efficacy.
