* MrImagination: Takumi has far too many delusions ''not'' to qualify. Though this is more of a deconstruction, considering he's insane...

* ScaryShinyGlasses: Yua
* SlasherSmile

The game has a SpiritualSuccessor in ''SteinsGate'' and ''Robotics;Notes''.

** KentaMiyake as Norose is basically reprising his role as Rosenberg in ElCazador, except with scary teeth and [[spoiler:a {{BFS}}]].

* ImagineSpot: Pretty much defines Takumi's 'delusions', but it seems as though he doesn't remember them. Some might go into DaydreamSurprise territory, except they're obvious to the audience, particularly because you have to trigger them yourself in the game.

* WellIntentionedExtremist: Norose. The fact that he's also a NietzscheWannabe pursuing his goals to extremes that make him a CompleteMonster tend to make him less than sympathetic, though.

The game has a SpiritualSuccessor in ''[[SteinsGate Steins;Gate]]'' and ''Robotics;Notes''.

* [[spoiler: AngstySurvivingTwin]]: [[spoiler: Yua. Her twin sister [[ThemeTwinNaming Mia]] died in the "Group Dive," the ''first'' First Gen incident. Yua then launches her own investigation into [[ThemeTwinNaming Mia]]'s death. She suspects Takumi is involved in the First Gen murders and pretends to befriend him under the ruse of being a [[GamerChick girl otaku]]. When Takumi finds out her true intentions, Yua ... [[NotHerself doesn't]] [[ScaryShinyGlasses take]] [[DepartmentOfRedundancyDepartment it well]]]].

* BlandNameProduct: Deluoode for Google, and We-Key Pedophilia[[hottip:*:the Encyclopedia of Useless Knowledge]] - seriously - for TheOtherWiki.

** [=MewTube=] (YouTube) and @-Channel (2-Channel).
*** ...both of which would later resurface (and play major roles in) ''[[SteinsGate Steins;Gate]]''.

* BreakTheCutie: ''Every single heroine''. [[spoiler:It's the basic requirement to obtain a Di-Sword, after all...]]

* [[CantYouReadTheSign Can't You Read The Sign?]]: @chan has a "20 years or older" rule, clearly seen every time Takumi (17) is reading it.

* DeusSexMachina: Many of Takumi's delusions are about him randomly having sex with one of the girls.
* DiabolusExMachina: Route B is one huge ever-expanding example of this, featuring among other things, [[spoiler:a DespairEventHorizon (Sena) and BodyHorror AndIMustScream (Kozue), all of which culminates in a LetThemDieHappy MercyKill JustBeforeTheEnd for a ShootTheShaggyDog ending]]. And the reason why it all happened? [[spoiler:Kozue got knocked unconscious during the earthquake]].

* {{Dojikko}}: Kozue. Also Yua, in the anime.

* {{Evolving Credits}}: Very subtlely done in the opening. In certain parts, Takumi's facial expressions change as the series progresses, becoming more confident. Only really obvious if you watch the openings side by side.

* EyesAlwaysShut: Detective Ban's right eye is almost always closed, giving him a Series/{{Columbo}}-esqe appearance.

* FakeBand: Phantasm. Their lead singer is FES, also known as Ayase Kishimoto.

* HairColors: Fifty-fifty split - Rimi, Kozue and [[{{You Gotta Have Blue Hair}} Ayase]] have them, while Yua, Sena, and Nanami have more normal blonde and black shades.

* [[ItsASmallNetAfterAll It's A Small Net After All]]: Averted most of the time, there are random comments, spam e-mail, and useless search results.

* ImaginaryFriend: Seira, from ''[[{{ShowWithinAShow}} Blood Tune]]''

* TechnoBabble

** And in one of the delusions, Takumi is called on his phone by an (otherwise nonexistent) incredibly generic Tsundere love interest, whose every second sentence is "It's not that I like you or anything".

* UnwantedHarem: While [[spoiler:except for Rimi]] none of them are after Takumi romantically, elements of the genre are invoked in a fashion. Official art usually depicts Takumi with the six leading girls of the show in a way reminiscent of it as well.

* VirginPower
--> '' '''Takumi:''' [[InsultBackfire Earlier, you called me a Cherry-Boy.]] [[PreAssKickingOneLiner Did you know? Virgins have incredible imaginations!]]''

* HotChickWithASword: They all might use Di-Swords, but it's Sena who belongs to this trope.

When the story begins, he is only know to have even semi-regular interactions with a few people: his [[AnnoyingYoungerSibling bratty younger sister Nanami]], his ESO [[BandOfBrothers guild partner Grim]] (whom he speaks to online), the school's [[HandsomeLech resident playboy Misumi]], and Seira, whom he has become deluded into thinking she exists and can hear her talking and interact with her as kind of muse. Beyond these, he seems to be quite afraid of interacting with people, exhibiting classic signs of social phobia (such as extreme discomfort with making eye contact).

* CastFromLifespan: Any Gigalomaniac that overuses their powers risks severe damage to themselves. [[Spoiler: Shogun is very far along with process, thanks to constant use of his powers.]]

* [[spoiler: ClonesArePeopleToo]]: [[spoiler: Shogun considers Takumi to be a real person, and he wants Takumi to live on after his imminent death. In ending AA, Rimi agrees with Shogun.]]

** [[spoiler: When Suwa tries to catch Takumi in a delusion to distract him long enough to attack, Takumi turns it around on him, forcing Suwa to kill himself.]]

* DownerEnding
* DysfunctionJunction -- We'll be here all day if we try listing all of the crazy in this show.

* {{Evolving Credits}} -- Very subtlely done in the opening. In certain parts, Takumi's facial expressions change as the series progresses, becoming more confident. Only really obvious if you watch the openings side by side.
* {{Expospeak}} -- Halfway through the anime they seem to replace the UnreliableNarrator stuff with massive amounts of technobabble.

* EyesAlwaysShut -- Detective Ban's right eye is almost always closed, giving him a Series/{{Columbo}}-esqe appearance.
* EyesOfGold -- Takumi (in certain lighting), Yua, [[spoiler: her twin sister Mia]], Shino.

* FictionalVideoGame -- ''Empire Sweeper Online''

* FlashForward -- The show starts with one
* FormulaicMagic -- fun[[superscript:10]] × int[[superscript:40]] = Ir2, [[spoiler:the equation Takumi discovered in elementary school and the basis of the Noah Project]]. What the equation actually signifies is never explained in depth.

* {{Geek}} -- Takumi. Yua acts like one to get Takumi to trust her.
* GirlWithPsychoWeapon -- The entire core female cast.

* GoMadFromTheRevelation -- Sena's mother. [[spoiler: She was secretly used as a test subject for creating matter from delusions artificially. Since her second child and Sena's little sister mana died shortly after birth, they created a new baby from artificial delusions and gave it to her. Sena's father was against turning her into a guinea pig, but also didn't want her to realize that her child had died, so he reluctantly approved. The experiment continued for several years, until it was decided that enough results were gathered from it and it will be halted. Sena (who didn't know about the experiment) unfortunately happened to be there when they turned the machines off, causing her mother to freak out upon realizing she's been carrying a corpse and proceeded to stab her own eyes out with a scissor. All while Sena could do nothing but watch.]] No wonder she hates her dad.

* HealingFactor
* HeyItsThatVoice -- Take a seat. There's a few.

* HospitalHottie -- Shino. Also a {{Meganekko}}, to an extent.
* HotChickWithASword -- They all might use Di-Swords, but it's Sena who belongs to this trope.
* [[ItsASmallNetAfterAll It's A Small Net After All]] -- Averted most of the time, there are random comments, spam e-mail, and useless search results.
* ImageSong -- Each heroine has her own ImageSong that plays during the credits of her respective route in the XBox360 version of the VisualNovel
* ImaginaryFriend -- Seira, from ''[[{{ShowWithinAShow}} Blood Tune]]''
* ImagineSpot -- Pretty much defines Takumi's 'delusions', but it seems as though he doesn't remember them. Some might go into DaydreamSurprise territory, except they're obvious to the audience, particularly because you have to trigger them yourself in the game.

* InterruptedSuicide -- [[spoiler:Ayase. Takumi's first conscious use of his delusionary abilities in the game is to create a flowerbed which breaks her fall after she attempts suicide by jumping off the roof of the school.]] And later on, [[spoiler:Takumi himself]].

* LighterAndSofter -- ''Chaos;Head Love Chu Chu'', a true UnwantedHarem romantic comedy version that's actually a sort of sequel to the main series of events.

* ManicPixieDreamGirl -- Takumi hopes that Yua, and later Rimi are this.
* {{Meganekko}} -- Yua, [[spoiler: [[NotHerself most]] [[ScaryShinyGlasses of the]] [[DepartmentOfRedundancyDepartment time]]]].

* MrImagination -- Takumi has far too many delusions ''not'' to qualify. Though this is more of a deconstruction, considering he's insane...

* NewTransferStudent -- Kozue.
* NietzscheWannabe -- Norose.
* NinetyPercentOfYourBrain -- Norose's reasoning for how the abilities of Gigalomaniacs work.
* {{Otaku}} -- Takumi. Specifically of the Anime sort, though he ''really'' likes his {{MMORPG}}.

* PsychicLink -- [[spoiler:Kozue uses this to communicate telepathically. Kind of. It's stated that somehow it is entirely different because it runs off the power of delusions]].
* ScaryShinyGlasses -- Yua

* ShowWithinAShow -- ''Blood Tune''. All the audience really knows about it is lead character Seira, who Takumi is deluded enough to see talking to him.
* SplitPersonality -- [[spoiler: Subverted]]
* SpoilerOpening -- The gradual reveal of the different Gigalomaniacs throughout the story isn't quite as exciting after you see all but two of them with their Di-Swords in the opening.

* SuspiciouslyAproposMusic -- In all three versions of ''Chaos; Head'', the music by Phantasm is not only apropos, it's plot important, since it seems to be predicting the New-Gen events.

* [[spoiler:TakingTheBullet -- Sena's father, Hatano.]]
* TallDarkAndBishoujo -- Sena.

* [[spoiler: ThemeTwinNaming]] -- [[spoiler: Yua and Mia]].
* ThirdPersonPerson -- Kozu-pii

* TrademarkFavoriteFood -- Sena loves popsicles.

* {{Tsundere}} -- Sena. She even has a ShoutOut to [[ShakuganNoShana Shana]], Nanami also shows tsundere traits focusing on un-giver strategy

* [[spoiler: TwinSwitch -- The game and anime alike drop a lot of hints that the girl we know as Yua was actually her twin, Mia. The incident that gives her her Di-Sword has her conclude that it doesn't matter which one she is.]]

* UnwantedHarem -- While [[spoiler:except for Rimi]] none of them are after Takumi romantically, elements of the genre are invoked in a fashion. Official art usually depicts Takumi with the six leading girls of the show in a way reminiscent of it as well.

* UpdatedRerelease -- ''Chaos;Head Noah'', for the [=XBox=] 360. Changes to the game include adding routes for each of the girls and changing it to widescreen. [[spoiler: They also changed the route system; you now have to finish each route to unlock the True Ending, which can then be directly selected from the Main Menu.]]

* WellIntentionedExtremist -- Norose. The fact that he's also a NietzscheWannabe pursuing his goals to extremes that make him a CompleteMonster tend to make him less than sympathetic, though.

* WrongGenreSavvy -- Sometimes Takumi thinks of himself as a character in an RPG.
* {{Yandere}} -- ''Everyone.''
* YouGottaHaveBlueHair -- Ayase.

* ZettaiRyouiki -- Rimi and Kozue.

* AllJustADream -- Some of the positive delusions try to provide a HappyEnding through this, Takumi even [[LampshadeHanging lampshades]] the cliche.
* [[spoiler: AngstySurvivingTwin]] -- [[spoiler: Yua. Her twin sister [[ThemeTwinNaming Mia]] died in the "Group Dive," the ''first'' First Gen incident. Yua then launches her own investigation into [[ThemeTwinNaming Mia]]'s death. She suspects Takumi is involved in the First Gen murders and pretends to befriend him under the ruse of being a [[GamerChick girl otaku]]. When Takumi finds out her true intentions, Yua ... [[NotHerself doesn't]] [[ScaryShinyGlasses take]] [[DepartmentOfRedundancyDepartment it well]]]].

* CharacterBlog -- Part of the website for ''Chaos;Head Noah'' features blogs by each of the six main girls and one for Takumi.
* TheChessmaster -- [[spoiler: Norose]].

* CruelAndUnusualDeath -- The New Gen murders. However, the 2nd incident easily takes the cake ''and then some'' after you get know the circumstances of the murder. [[spoiler: Nurse Hazuki, who together with Suwa is the culprit behind all these cases, restrained the unlucky guy on a operating table and proceeded to vivisect him '''without any sort of anesthesia'''.]] [[ItGotWorse And that isn't even the worst part]]. Remember that an unborn child was inserted into his body? [[spoiler: That's Hazuki's baby of whom Suwa is the father. How it got into that guy's body you ask? Well, after slicing the victim open, she - I shit you not - proceeded to cut her own womb open, rip the fetus out and shove into that guys stomach. And she did this '''without any anesthesia''', all while sprouting an SlasherSmile par excellence and mumbling stuff in some sort of trance.]]
* CuteAndPsycho -- Two. Nice with some disturbing and murderous traits: [[spoiler:Kozue]]. Jerkass psychopath with a veneer of civility: [[spoiler:Suwa]].
* CuteMute -- Kozue, at first.
* DepartmentOfRedundancyDepartment -- [[spoiler:Serious-mode Yua]] has a habit of emphasizing sentences by repeating them several times in a row with slightly different phrasings.
* DeusSexMachina -- Many of Takumi's delusions are about him randomly having sex with one of the girls.
* DiabolusExMachina -- Route B is one huge ever-expanding example of this, featuring among other things, [[spoiler:a DespairEventHorizon (Sena) and BodyHorror AndIMustScream (Kozue), all of which culminates in a LetThemDieHappy MercyKill JustBeforeTheEnd for a ShootTheShaggyDog ending]]. And the reason why it all happened? [[spoiler:Kozue got knocked unconscious during the earthquake]].

* EmotionEater -- This is how the Di-Swords function.

-->''Those eyes... who's are they?''

* NinetyPercentOfYourBrain -- Norose's reasoning for how the abilities of Gigalomaniacs work. Also that 80% of the brain is used for processing visual data.

A fan translation patch for the game exists, but was taken down from the main site due to an agreement with Nitroplus, with unfortunately lead to DevelopmentHell as there's localized version of the game yet, in fact no news after the "agreement" between the original fan translators and Nitroplus were given.

* EyesAlwaysShut -- Detective Ban's right eye is almost always closed, giving him a {{Columbo}}-esqe appearance.

* GratuitousEnglish -- "New Gen" and a few others. Also the ending theme in the anime is about 75% SurprisinglyGoodEnglish. Seriously, it sounds like they called in an American to sing it.

** The list goes on, believe me - Taboo! (Yahoo!), Slavecard (Mastercard), Grouchosoft Mindorz X Perfect (Microsoft Windows XP Premium... seriously), TWO different [=McDonald's=] spoofs ([=McDeinald's=] and [=WacTiKald's=])... there are easily a half dozen of these in each chapter of the game, and the anime adds in even more.

->A shipping container on the roof. Sounds [[MindScrew crazy]], no?
