History Characters / ChaosHead

* TomatoInTheMirror: He's really a delusional existence created by Shogun, the real Takumi Nishijou.

!The Real Takumi Nishijou

* SuperLoser: He's a rude, selfish hikikomori with the power to make delusions real. Near the end he even embraces it and sneers at the adulation of the crowd after catching the killer. In his eyes, he's a loser through-and-through no matter how they want to look at him.

* ArtificialHuman: Quite literally a (real booted) figment of someone's imagination. In this case, that of the real Takumi Nishijou.

The main protagonist, a 17 year old second-year student at Suimei Academy who barely visits school in the first place. He spends most of his time playing Empire Sweeper Online, in which he is the most famous and powerful player (known as [[SpellMyNameWithAnS Neidhart/Knightheart]]).

* AwesomeMcCoolName: His username of "Lightning Fast Neidhardt" is supposed to give off the air that he's cool and unstoppable (which he actually is, in the game world of ESO as the strongest player).

* MeaningfulName: The kanji characters for his name can translate to "Lightning-fast Neidhardt blossoming the snake." Neidhardt is obvious, blossoming refers to how his DI-sword and personality (as revealed in the [=NoAH=] version of the game) is named/represents a Water Lily Stem as he opens up to people (blossoming) and moves forward after resolving himself (the stem). The Snake alludes to the serpent he creates with his delusions to smite and destroy Noah II at the end of the game. Said Snake also represents Takumi repeating the original sin from the story of Adam and Eve, as Adam rejected paradise for the sake of the woman he loved because of the temptations of a Snake, so does Taku in destroying Noah II with the power of a Snake that represents his deepest desires, all for the sake of Rimi.

* ShrinkingViolet: Takumi goes out of his way to avoid contact with other people as much as humanly possible. He actively tries to make himself not stand out at school and "become like the air" so DQNs and the like won't bother him. He has severe social anxiety which makes it hard for him to hold any type of conversation, and tries to convince himself into thinking 3D girls are disgusting so he's less inclined to interact with them.

* [[spoiler:TakingTheBullet]]: In the [=NoAH=] version of ''Chaos;Head'', [[spoiler:he does this for Sena believing that he's invincible because of a cheat code he was told that would be activated. It doesn't work.]]

* [[spoiler:AccidentalMurder]]: In Chaos;Head [=NoAH=] [[spoiler: she accidentally kills Sena during her character route because Kozue attacked her before she could undo the delusion she'd placed on Sena.]]

* ColdBloodedTorture: In Chaos;Head [=NoAH=], it's revealed [[spoiler: that for an entire year, Rimi was sliced, starved, waterboarded, as well as many other unseen forms of torture by Norose in order to make her awaken as a Gigalomaniac, to the point where she created multiple personalities for herself to escape the suffering.]]

* {{Deuteragonist}}: She's the most fleshed out girl in the common route and actually gets first person perspective in her Chaos;Head [=NoAH=] route which no other girl does. (Science Adventure typically allows the Deuteragonist to have this privilege for most of the mainline entries, whereas the other girls of their respective casts never get the privilege of.)

* AngstySurvivingTwin: Her twin sister [[ThemeTwinNaming Mia]] died in the "Group Dive," the ''first'' First Gen incident. Yua then launches her own investigation into 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, she [[NotHerself doesn't take it well]].
** Chaos;Head [=NoAH=] reveals [[spoiler: that she is actually Mia, and Yua died in her stead after volunteering to go to a group offline meet up to make a good first impression on her behalf. That, coupled with years of neglect from their parents as Mia, her parents forgetting about "Mia" who was believed to be dead, and Mia blaming herself for Yua's death, caused her to believe she was Yua and develop a split personality. It also gave her enough mental trauma that seeing a delusion of her dead sister claiming that she took on a false persona is enough to push her past the mental brink to obtain a DI-sword and awaken as a Gigalomaniac.]] Angsty is correct.

* CatchPhrase: "Is the scenery your eyes perceive the real thing?" She usually uses this phrase to gauge whether or not the other party is a threat, as she notes to herself in Chaos;Gate (the short story crossover where she meets Okabe from ''VisualNovel/SteinsGate''.

* {{Kuudere}}: More heavily emphasized in her [=NoAH=] route where she gets into an embarrassing situation with Takumi and is easily flustered. In general however, she tends to constantly maintain a stoic front to hide her true feelings about how fragile she is after witnessing half of her family's traumatic murders, as well as running from her emotions with a wall of logic about how the world is run by electrical impulses and devices instead. She even has a ShoutOut to LightNovel/{{Sha|kuganNoShana}}na.

* BoyishShortHair

* {{Kuudere}}: She's blunt and standoffish, but really is just emotioanlly stunted and doesn't know how to properly express her feelings unless with someone she can fully trust in, like how she grows to trust Takumi.

* ProperTightsWithASkirt

* [[spoiler:GoOutWithASmile]]: [[spoiler:He dies smiling, after having achieved his goal of atoning for Noah II by having Takumi destroy it, while holding Nanami's restored hand.]]

[[caption-width-right:300:[[labelnote: Click to see her ''Awakening'' outfit.]][[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/seiraawakech.png]] [[/labelnote]]]]

* ToxicFriendInfluence: She heavily encourages Takumi to stay in the "2D world" over the 3D world and encourages more of his bad {{Hikikomori}} habits. This is [[{{Downplayed}} downplayed]] in the sense that the Seira in Takumi's head is really just a manifestation of his weak willed thoughts and desire to isolate himself and escape from the pain in his reality, as the real Seira character in the in-universe Blood Tune anime does not actually know Takumi.

* {{GIRL}}: Inverted, as she pretends to be a guy as Grim when playing the MMO Empire Sweeper Online.

* AbusiveParents: Subverted. He initially only used his wife as a labrat to better her life and prevent her from grieving over the loss of their baby daughter, but it all goes horribly wrong once Norose and NOZOMI end the experiment and she's forced to face reality, going insane from it and killing herself.

* ArtificialHuman: Quite literally a figment of someone's imagination. In this case, that of the real Takumi Nishijou.

* {{Portmanteau}}: '''[[Creator/GenUrobuchi Gen]]''' [[Creator/GenUrobuchi Uroba]]'''[[Creator/GenUrobuchi chi]]''' (with an added "i").

** He is also inadvertently responsible for traumatizing his daughter enough for her to awaken as a Gigalomaniac, and she was taken to Ark Heart Medical for months before she escaped, thoguh this was not of his own volition.

* TheHeavy: Along with Hazuki, he is the one directly carrying out the New Gen murders on behalf of [[BigBad Genichi]].

* ToxicFriendInfluence: {{Downplayed}}. Encourages Takumi to stay in the "2D world" over the 3D world and encourages more of his bad {{Hikikomori}} habits. [[{{Downplayed}} However]], she's not doing it with any genuine malicious intent as she wants him to feel safe without bringing harm to him or anyone else.

* OnlyKnownByTheirNickname: Only Rimi and NOZOMI know him as Shogun, Takumi doesn't find out the truth about him until the end of the game and refers to him as "Shogun" for most of the plot.

* ThirdPersonPerson: Not only that, but she also speaks of herself in third person by using a nickname, "Kozu-pii/Kozzy".

* GoOutWithASmile: [[spoiler:He dies smiling, after having achieved his goal of atoning for Noah II by having Takumi destroy it, while holding Nanami's restored hand.]]

!!The Black Knights

* TrademarkFavoriteDrink: He's almost always downing Science Adventure's version of Coca-Cola whenever he can.

* TheConfidant: She becomes the only person Takumi can go to for confiding in about his fears regarding New Gen. While she plays dumb to knowing about the truth, she still comforts him and provides emotional support to soothe him during his difficult times.

* SplitPersonality: Takumi starts to think he had one that was responsible for the New Gen killings. He was wrong, but there is another version of him in a different body.

* WalkingSpoiler: The only thing known about her at the beginning is that she is a mysterious “demon girl” who seems to be the New Gen killer. The revelations of who she really is coincide with the truth of the New Gen killings.

* DisappearedDad: The entire reason that she's in

* NewTransferStudent: How she is introduced.

* SamusIsAGirl: As Grim, her ESO handle, she pretends to be a guy.

* SupportingLeader: She has a personal tie with the NOZOMI organization, so she ends up being a major mover of the plot.

* EmotionlessGirl: Likely as a result of her torture, she has a hard time expressing feelings towards other people, and mostly maintains a stoic demeanor like Sena.

* SuperpowerDisability: Shogun is probably the strongest Gigalomaniac in the story due to using his powers practically from the day he was born and having immense experience with them as a result. The downside is that this has caused his body to weaken significantly to the point where he's physically crippled. This can happen to any Gigalomaniac that abuses their powers, which is why Sena encourages everyone not to overuse them.

* ProperlyParanoid: He ends up being this multiple times. Yua really did have ulterior motives in getting close to him, Rimi actually did brainwash most of his class into thinking she was a classmate all along and had alterior motives for getting close to him (though they were in his best interest), and Shogun truly was trying to shock him into awakening as a Gigalo.

* RefusalOfTheCall: Takumi spends the entire game running around from New Gen to avoid being caught up in it, despite the fact that the reason it is centering around him is for the purpose of multiple people trying to force him to obtain his DI-sword so he can settle things with NOZOMI, for better or worse.

* ItSucksToBeTheChosenOne: Takumi was chosen (or rather, created) by Shogun to become an awakened Gigalomaniac that will save the world from Noah II. The downside is that this results in him living out a fake existence as a clone of someone else, who is persecuted for 2 months straight by NOZOMI and Shogun, both of which are trying to mentally torment him into awakening. This also results in over 10 innocent people murdered, his sister being kidnapped as well as her arm being chopped off, the entire city leveled by a massive earthquake that kills thousands, the only girl besides Nanami that he loved and who also reciprocated his feelings gets kidnapped, and Takumi himself nearly mentally destroyed in a climactic battle with Norose for all his troubles. [[EarnYourHappyEnding At least he gets to live happily after surviving that nightmare of a situation.]]

* MeaningfulName: The kanji characters for his name can translate to "Lightning-fast Neidhardt blossoming the snake." Neidhardt is obvious, blossoming refers to how his DI-sword and personality (as revealed in the [=NoAH=] version of the game) is named/represents a Water Lily Stem as he opens up to people (blossoming) and moves forward after resolving himself (the stem), and the Snake alludes to the serpent he creates with his delusions to smite and destroy Noah II at the end of the game. Said snake also represents Takumi repeating the original sin from the story of Adam and Eve, as Adam rejected paradise for the sake of the woman he loved, so does Taku in destroying Noah II for the sake of Rimi.
* MrImagination: Deconstructed. His detachment from reality goes up to the point where he could be diagnosed with schizophrenia.
* NerdsAreVirgins: Grimm constantly pokes fun at him for this, and Takumi does want to get laid but has accepted he'll never find a girlfriend. He does end up falling in love with and dating Rimi at the end of the game though, so maybe there's hope for him yet.
