History Characters / Kiznaiver

* BuxomIsBetter: Yuta points out her large breasts as a major charm point. [[DeadpanSnarker She tells him]] [[FormerlyFat his were probably bigger in grade school.]]

* [[EmotionlessGirl Emotionless Boy]]: He shows very muted emotional responses to the events around him. Not even being pushed down a flight of stairs gets much reaction from him. According to Chidori, he wasn't always like this.

* [[OnlySaneMan Only Sane Woman]]: Has the most normal personality out of the Kiznaivers.

* [[OnlySaneMan Only Sane Woman]]: Despite her odd looks and {{Cloudcuckoolander}} tendencies, she is the most emotionally and psychologically stable character. She is also the first one to be willing to put everything on the line to help her friends, even if it means making everybody forget their petty fights.

* [[BigBrotherInstinct Big Sister Instinct]]: She states that her life as a [[spoiler: scientist for the original Kizuna System]] was like having a bunch of younger siblings. It's unknown if Yamada felt the same.

* [[MrExposition Ms. Exposition]]: She explains in detail the workings of the Kiznaiver system, the whole [[spoiler: history of the original Kiznaivers and Sonozaki.]]

* IllGirl: She was born with a type of kidney disease that ensured she would die young.

->'''Voiced by:''' Misaki Kuno (Japanese), Katrina Salisbury (English)

* BungledSuicide: [[spoiler: Implied to be what happened to her on the beginning of episode 1 and what she was going to do in episode 10.]]

** Taken UpToEleven in episode 8 when he [[spoiler:ditches Chidori ''while she's confessing'' to look for Sonozaki. Granted, Sonozaki would have died if he hadn't but still. The guy needs to learn tact.]]

* BandageBabe

* AllLoveIsUnrequited: [[spoiler: Yuta is in love with Maki, who is in love with [[TheLostLenore Ruru]]. Meanwhile, Katsuhira and Sonozaki are ambiguously in love with each other, while Chidori is in love with Katsuhira, Tenga is in love with Chidori and Nico is in love with Tenga.]]

* BreakingTheFellowship: [[spoiler: Episode 10 reveals that they decided to separate themselves to avoid further pain and the possibility to read each other thoughts.]]
** PuttingTheBandBackTogether: [[spoiler: Nico still wants everybody to be friends, and Katsuhira and Hisomu seem to want it too, so she plans to do it. It's implied that all of them actually want this too. Katsuhira seems to pull this off in episode 11, by putting his heart out and stating that they were already friends during the summer.]]

* HeroicBSOD: Though Maki goes through one alone during episode 6 and 7, episode 9 ends with them all sharing [[spoiler: the emotional pain of their fear of not being able to be friends and the pain of no one getting their feelings returned.]]
* InvisibleParents[=/=]ParentalAbandonment: None of their parents are ever seen, if they even have parents.
** Nico mentions her father is a doctor and her family is rich, Katsuhira's parents work overseas and send him money, and Tenga claims his parents don't care where he is. The other four families are never mentioned, although Honoka appears to live in a normal middle-class house.
* ThePowerOfFriendship: Invoked by Katsuhira and Urushibara in episode 11: [[spoiler: the Kiznaivers all feel Katsuhira's emotional pain, even without the Kizuna System, meaning that the pain they felt from watching Katsuhira suffering came fully from how close they have become and their own empathy towards him.]]

* OddFriendship: A group composed by people who would never hang out or interact in any other situation, obviously, their friendship would be considered weird for an outsider. This even gets lampshaded by Yuta's admirers when they see him with Tenga.

* TrueCompanions: While they were off to a rocky start, Nico particularly is working towards making the group this. [[spoiler: After episode 9, it's not working.]]
** In episode 11, Katsuhira [[spoiler: talks about how much he wants them to be friends again and that they were already friends during the Kizuna experiments by the fact they trusted each other in dangerous situations.]]

* AllMenArePerverts: He is the subversion of the group. You have Tenga, who has shades of a LovableSexManiac, TheCasanova Yuta and a teacher who plays dating sims in the middle of the class, but Katsuhira's lack of interest in a girl who openly likes him and Sonozaki's SmellsSexy scene seem, by comparison, almost asexual.
** It might be just ''really'' downplayed, as he does notice the pattern of Sonozaki's panties as he's falling down the stairs.
** However, he actually attempts to look for Sonozaki by identifying the panties of passing girls as he watches from a floor below.
* AllOfTheOtherReindeer: Was bullied since childhood due to his [[FeelsNoPain inability to feel pain]] and [[EmotionlessGirl lack of emotion]].
* AlwaysSaveTheGirl: Zigzagged. He saves [[spoiler: Sonozaki in episode 8, but before that, he gets saved by Chidori in episode 2 and when both him and Sonozaki are drowning, she is the one that saves him.]]
* AffectionateNickname: Chidori calls him "Kacchon."

* CharacterDevelopment: [[spoiler:In Episode 5, he starts showing a backbone when he demands that Kamaishi return the money that was taken from him as it has caused Chidori pain. This continues into the next episode, when he outright tells Sonozaki that he doesn't approve of the methods she's taking]].

* InnocentlyInsensitive: Since he believes worrying about him would be a bother, Katsuhira offers to forget Chidori's confession ever happened. However, this comes across as insensitive to Chidori, annoying her.

* MyGodWhatHaveIDone: Has this in episode 9, after realizing that what triggered [[spoiler: the chain of awful feelings of rejection and UnrequitedLove between the Kiznaivers was his inability and unwillingness to properly deal with Chidori's feelings for him and being oblivious to the tangled LoveDodecahedron between the Kiznaivers.]]
* NotSoStoic: As part of his character development, [[spoiler: he starts developing emotions and showing them, smiling and crying becoming things he is able to do.]]

* ACupAngst: Takashiro has a little. When Sonozaki asks them to look deep within their [[VisualPun chests]] [[note]]Means "Deep within your heart" in Japanese, but the kanji for "heart" is actually "chest."[[/note]], Tenga points out that it would be hard for her to look with such small boobs. Chidori is understandably unhappy with Tenga.
** She seems to be insecure about her size after seeing Sonozaki's sizeable bust.

* DarkSecret: [[spoiler: She was in love with Katsuhira in the past]].

-->'''Nico:''' [[spoiler:You don’t want to get rejected? That’s not fair. Tenga-kun will yell at those two. He’ll probably stop them... so you can just stay right here and not do anything!]]

* AcceptableTargets: He only beats up [[BullyHunter people he considers twisted]], but in effect he essentially bullies the bullies. In his own words he "enjoys raking them over the coals" rather than merely stopping them or avenging their victims.

-->'''Tenga[[spoiler:*In thought*]]:''' [[spoiler: Why, Chidori? Why do you like Katsuhira more than me?]]
* AssKicksYou[=/=]DynamicEntry: Tenga shoves his ass into a bully and sits on him until he passes out.

-->'''Tenga:''' [[CallingYourAttacks Hip... ]]''[[LargeHam SUMMER!]]''

* {{Hotblooded}}: Almost everything that he says is at a yell and he's very easily excitable.

-->'''Tenga:''' My birthday's September 18th, and I'm a Virgo! My blood type is O! My hobbies are fishing for crawfish and [[BullyHunter raking guys who are twisted over the coals!]] How's ''THAT?!''\\

* TheMatchmaker: Offers to help out Chidori with Katsuhira.
** MatchmakerCrush: [[spoiler: Revealed to have one on Chidori in episode 8]].

* ShipperOnDeck: For Katsuhira and Chidori in a very playful way, reacting ecstatically to them being next-door neighbors. Later moves on to TheMatchmaker to help her.
** [[spoiler: Brutally, heartwrenchingly deconstructed in episode 9. He slowly began to develop feelings for Chidori after offering to be TheMatchmaker, and it's heavily implied that he kept up the illusion of supporting her efforts to win over Katsuhira because he [[IWantMyBelovedToBeHappy simply wanted to make both of his friends happy.]] ]]

* ThrowTheBookAtThem: [[EstablishingCharacterMoment In his first scene]], he precedes his [[DynamcEntry flying]] [[AssKicksYou hip-check]] by throwing his school bag at a bully's face with the velocity and accuracy of a fastball.

* WouldNotHitAGirl: Implied. When Chidori asks him to hit her [[spoiler: to help look for Hisomu]], he clearly hesitates and looks uncomfortable with the idea.
** WouldHitAGirl: That being said, he does not consider Sonozaki a girl, as revealed in episode 9, calling her "the enemy" and not being even a little bit bothered with the idea of beating her up.

* AlliterativeName[=/=]RepetitiveName: '''Ni'''co '''Ni'''yama.

* BetterAsFriends: Episode 10 shows that she wants everybody to be friends, [[spoiler: even if it means her feelings won't be returned.]]

* ClingyJealousGirl: [[spoiler:Nico seems to be taking Tenga's efforts as TheMatchmaker as signs that he has a crush on Chidori and noticeably looks very displeased as a result. And when it turns out that he does have a crush on her...]]
** Later subverted when [[spoiler:she becomes the first member of the LoveDodecahedron to accept the unrequited nature of her feelings and, despite wanting to keep Tenga for herself as her thoughts reveal, she chooses not to act upon it and ignores her feelings for friendship's sake.]]

* {{Foil}}: While it is shown from the start the differences between [[GirlNextDoor sensible, down-to-earth Chidori]] and [[GenkiGirl eccentric, strange Nico]], some scenes, particularly in Episode 9, highlight deeper differences between them. [[spoiler:Both girls are facing the pain of unrequited feelings; however, while Nico accepts that Tenga does not feel the same way about her and goes out of her way to face rejection, Chidori refuses to face her fears or acknowledge the rejection she indirectly suffers. Likewise, on Episode 10 it's how Nico chose to prioritize friendship above her feelings as a way to heal, while Chidori's way to heal was to isolate herself from all her friends in order to deal with her feelings.]]

---> '''Chidori:''' Niyama-san, what's wrong?
---> '''Nico:''' Nico is looking for Zantoman.
---> '''Chidori:''' Zantoman?
---> '''Nico:''' Yeah! It's the fairy of sleep. When it throws sand at you, the sand gets into your eyes, and it's like "ow, ow, ow!" and you fall asleep, and dream, and lots of marbles fall from the sky!

* TheHeart: Is the most emotional member of the cast and is working really hard to try to get everybody to be friends.
** At the end, she succeeded.

* ObliviousToLove: Averted, [[spoiler: she is completely aware of the LoveDodecahedron between the Kiznaivers and that her crush on Tenga is unrequited.]]

* WhatTheHellHero: Calls Chidori out several times in episode 9 in regards to the fact that she [[spoiler: is so caught up in trying to get Katsuhira she doesn't realize she is doing the same thing to Tenga.]] She also calls her out for her fear of [[spoiler: getting dumped.]]

* ChubbyChaser: Played for laughs in the end, she wants Yuta to pudge out at least a little so he doesn't look attractive to other girls.

* TheStoic: Remains calm and collected throughout her appearances.
** NotSoStoic: That is, until she's confronted with her secret...
*** Not to mention her very visible disgust at [[spoiler:[[TooKinkyToTorture Hisomu's]] [[TheImmodestOrgasm orgasm]] from the pain.]]

* WhatTheHellHero: Nico calls her out in the last episode, when she thinks that [[spoiler: it's pointless to do anything for Katsuhira or Sonozaki, since they are not connected anymore and Sonozaki caused nothing but trouble, even pointing out she had already got rid of them.]]

* NonUniformUniform[=/=]CustomUniform: While she is in the same class as the others, her clothes are very different.

* PantyShot: Averted. Katsuhira gets a peek at Sonozaki's, but the camera doesn't actually show them.
-->'''Katsuhira:''' Polka dots...

* UsedToBeMoreSocial[=/=]UsedToBeASweetKid: Was a hell of a lot more cheerful [[spoiler: before the side effects of the Kizuna Project kicked in.]]

* AcceptableTargets: He only beats up [[BullyHunter people he considers twisted]], but in effect he essentially bullies the bullies.

* YouGottaHaveBlueHair: He has teal blue hair.

* {{Meganekko}}: Subverted. While she has the appearance of one, her personality doesn't match the trope.

* YouGottaHaveBlueHair: Light blue, to be exact.

* YouGottaHaveBlueHair: He has dark green hair.

* YouGottaHaveBlueHair: Purple in this case.

* MulticoloredHair: The majority of his hair is white, with the lower back and parts of the top being a light brown.
** LockedIntoStrangeness: Katsuhira initially had brown hair, but a certain incident turned his hair white. The lower back and the top of his hair are still brown though. [[spoiler: Urushibara reveals to him that this was a side effect from Katsuhira's previous Kiznaiver experiment where most of his emotions and senses were transferred to Sonozaki and never went back to him, causing his hair to prematurely grey.]]

* TheStoic
** NotSoStoic: As part of his character development, [[spoiler: he starts developing emotions and showing them, smiling and crying becoming things he is able to do.]]

* MulticoloredHair: Blonde with teal streaks.

* BeautyMark: Just below her right eye.

* {{Megane}}

* RomanticTwoGirlFriendship: [[spoiler:Her friendship with Ruru was almost this, but when Ruru confessed her feelings she ended their friendship to save herself the grief of losing someone close to her.]]

* RomanticTwoGirlFriendship: With Maki. When it was clear that she clearly had romantic feelings for Maki, the latter turned her down and ended their friendship out of fear of the grief that would come when she died.

* NotSoDifferent: As Hisomu points out, none of them have friends and barely know how to even make friends with others.

* DeathByDespair: Her parents don't seem to be aware of Ruru's unreciprocated feelings towards Maki, causing them to believe Maki was to blame for Ruru's disease acceleration due to Maki unfriending her.

* ZettaiRyouiki: Grade A on her right leg and Grade E on her left.

* ZettaiRyouiki: Grade A.

* SecondYearProtagonist: Like all of them.

* SingleWomanSeeksGoodMan: This is implied in the final episode to be the outlook Chidori ends up taking toward [[spoiler: [[SecondLove Tenga]]]]. [[spoiler: His {{Adorkable}} smile in response]] doesn't help to disprove the sentiment at all.

* {{Adorkable}}: The following exchange was her [[EstablishingCharacterMoment first scene in the series]]:
---> '''Chidori:''' Niyama-san, what's wrong?
---> '''Nico:''' Nico is looking for Zantoman.
---> '''Chidori:''' Zantoman?
---> '''Nico:''' Yeah! It's the fairy of sleep. When it throws sand at you, the sand gets into your eyes, and it's like "ow, ow, ow!" and you fall asleep, and dream, and lots of marbles fall from the sky!

* GenkiGirl: She's very energetic and cheerful.

* {{Adorkable}}: When ashamed.

* HairDecorations: Wears a hair clip to hold her bangs in place and fastens her hair in a ponytail with a scrunchie.

* HairDecorations: She accessorizes her pigtails with odd fur-puff monster hair bands with ribbons, hearts, and whatever those kinds of balls sticking out of her hair are; which is very much in-line with Music/KyaryPamyuPamyu's fashion sense.

* BiTheWay: [[spoiler: Had feelings for her friend Ruru, though she never followed through on them out of fear of losing Ruru to her disease. By the end of the show, after having had time to move on, she's open to a relationship with Yuta.]]

->'''Voiced by:''' Eiji Miyashita (Yoshizawa) and Kento Hama (Kamaishi) (Japanese), Alex Bergen (Kamaishi) (English)

* GrayEyes: Go hand in hand with her cold, distant demeanor.

* RedBaron: His neighbors gave him the name "Mad Dog" for his offensive behavior.
