History Characters / ClassroomOfTheElite

* GoodIsNotDumb: Definitely not. Her kind heart should not be mistaken for her being a pushover or a {{ditz}}, and her personality isn't weak by any means.

* MsFanservice: She has a few {{Shower Scene}}s, including one where she wears underwear on an island, and was shown in a bikini in a PoolEpisode.

* MsFanservice: She has several scenes in a bikini, a school swimsuit, and a ModestyTowel, usually paired with jiggle physics.

* MsFanservice: She's possibly the most well-developed girl in her grade and was shown wearing a bikini, as well as just her panties while getting a massage. She's also shown sunbathing on a [[https://you-zitsu.fandom.com/wiki/File:BD_DVD_Season_2_Kadokawa_Store_bonus.jpg Blu-ray/DVD Season 2 Kadokawa store bonus]].

* NatureLover: Proves to be one of the best people during the deserted island excursion. His previous camping skills come in very handy as he's able to identify a river, manages to start a campfire, and easily identifies various fruits some of the girls bring back.

* {{Foil}}: To Kushida. Both have another secret side to their personality which is found out by Kiyotaka, but Kushida's relationship with him is entirely antagonistic, and she grows to be so wary of him to the point she wants nothing more than to see him expelled to ensure her secret is safe. Karuizawa, on the other hand, gradually develops a genuine bond with him and later even forms a romantic relationship with him. Their time in middle school is also quite different despite both of them standing out. Kushida was LovedByAll due to her [[ExtremeDoormat willingness to be the class gofer]] before eventually losing her good standing by writing whatever secret her classmates told her of them on her blog to vent out stress and then spilling ''more'' secrets when being angrily confronted by them. Kei was viciously bullied by the other girls during middle school due to her headstrong and competitive nature, which psychologically damages her to the point of being willing to do ''anything'' as a way to NeverBeHurtAgain.

* DoubleDate: Secretly and with Kei's help, she has set up a double date on Christmas of her first year for her and Kiyotaka as well as Karuizawa and Hirata.

* MsFanservice: She's shown in a bikini on one of the illustrations in Volume 8 of Year 2, exposing her well-developed figure.

* SmallRoleBigImpact: She has a minor role, but she's the one who informs Kiyotaka Ayanokoji that Honami Ichinose intends to let Miyabi Nagumo date her in exchange for enough private points to buy an expelled student back, which allows Kiyotaka to prepare an alternative for her by making a deal with Ryuen's supporters instead, allowing to prevent the expulsions of both Ryuuen and Kanzaki. {{Downplayed|Trope}} in that he suspected that was her course of action to begin with.

* AdaptationalEarlyAppearance: In the light novel, she debuts during Volume 4.5 of Year 2. However, in the anime adaptation, she has an EarlyBirdCameo in Episode 8 of Season 3, which is back in the first year.

* SpannerInTheWorks: He has a minor role, but by taking part in spreading the rumors about Class D (C at the time) students, he provides one of the first hints of Kei and Kiyotaka's relationship, allows for Ayanokoji and Kushida's deal to happen, contributes yet another reason for Yamauichi's classmates to see him as InsufferableImbecile, and lets Ike and Shinohara's relationship make some progress.

* AdaptationalEarlyAppearance: In the light novel, she debuts during Year 2. However, in the anime adaptation, she debuts in Episode 8 of Season 3, which is back in the first year.

* AdaptationalEarlyAppearance: In the anime adaptation, she has TheCameo at the table when Class C is partying on the beach in Episode 10 of Season 1, before her proper debut in Episode 7 of Season 2.

* CassanovaWannabe: While trying to deduce the relationship between Kiyotaka Ayanokoji and Kei Karuizawa, he pretends to be interested in her to make it understandable why he'd be prying so much, hitting on her, with her turning him down. He also flirts with Masumi Kamuro, but she's not interested.

A girl in Arisu Sakayanagi's Class A who doesn't express herself much. She ends up in Kiyotaka's group during Exchange Meeting training camp.

* RomanticFalseLead: Kei Karuizawa flirts with him during the Cruise Ship Special Test so that he'd protect her from her bullies. However, she ends up never pursuing him afterwards.

* BrokenBird: [[spoiler:Her time in the White Room had left her mentally traumatized to the point that ''years'' after leaving the facility, her father states that she would only be able to listen to Kiyotaka.]]
* DoesNotLikeSpam: [[spoiler:What led to her first conversation with Kiyotaka and Shiro in the White Room was expressing her dislike of carrots during lunch period.]]

* PleaseDontLeaveMe: [[spoiler:She tearfully begs Kiyotaka to not leave her side when he coldly rejects any attempt to reconnect upon reuniting with her again.]]

* AlwaysSecondBest: Played with. [[spoiler:He's the second-best student behind Kiyotaka in the Fourth Generation of the White Room, but Shiro chooses to not go further in the curriculum due to his secret desire [[IJustWantToBeFree to be free]].]]
* ButNowIMustGo: [[spoiler:Unlike the other students of the White Room, Shiro was the first one to leave the facility by his own choice due to his desire to see the outside world. After the 4th Generation is down to just him and Kiyotaka, they have their last spar before Shiro tells his friend of his secret desire to leave the facility. Afterward, Kiyotaka narrates that that was the last time he ever saw Shiro.]]

* IJustWantToBeFree: [[spoiler:In their last spar, Shiro expresses his true desire to leave the White Room and see the outside world.]]

* TheStoic: Similar to Kiyotaka, Shiro doesn't emote much thanks to the White Room's brutal curriculum. [[spoiler:Though compared to Kiyotaka, Shiro was able to hold on to some semblance of his humanity to the point he chooses to leave the White Room on his own accord rather than being expelled.]]
* WalkingTheEarth: [[spoiler:It's implied he went abroad from Japan after leaving the White Room.]]

[[folder:Kiyotaka Ayanokouji]]

* CharlesAtlasSuperpower: Of the BadassNormal variant. It's clear from his encounter with Manabu early on that Kiyotaka is a ''lot'' more physically adept than he lets on. [[spoiler:His upbringing under the White Room]] includes intensive physical training as much as education, which gives him the peak-human level of fitness.

* ConditionedToAcceptHorror: Due to [[spoiler:his upbringing in the White Room]], nothing fazes him, barely reacting to things that would normally horrify and traumatize regular people. He doesn't even bat an eye when hearing about the suicides of his butler Matsuo as well as Matsuo's only son.

* ItAmusedMe: Not exactly his main motivation, but this is Kiyotaka's reason for challenging Manabu into a one-on-one running competition near the end of sports festival in volume 5. He even notes to himself it's very different and much more entertaining compared to his experience running indifferently in [[spoiler:White Room's facilities]].

* PhotographicMemory: Kiyotaka remembers everything he has done in his life ''since age 0'', a fact that stuns [[spoiler:the White Room researchers]].

[[folder:Kikyo Kushida]]

* VillainWithGoodPublicity: Since she hides behind a kind GenkiGirl persona, she's beloved by her classmates and even students from other classes. In the Class Poll, she ranked third place in getting positive votes. [[spoiler:Subverted later on once her true nature is revealed to the class.]]

* TokenWholesome: She's a pure person in general and can be seen wearing a jacket on top of her bikini in her [[TheCameo cameo]] at Class C's beach party.

* TheFriendsWhoNeverHang: After a rumor about Maya hating Onodera is spread, Sōshi Miyamoto points out that the two of them have never been hanging out with just the two of them.

* LivingProp: He's been given very little characterization and importance, mostly being used to just fill in the scenes of his class. Episode 4 of Season 3 of the anime gives him the most focus and even that's still a minor role.

* SmallRoleBigImpact: She has a minor role, but she's the one who informs Kiyotaka Ayanokoji that Honami Ichinose intends to let Miyabi Nagumo date her in exchange for enough private points to buy an expelled student back, which allows Kiyotaka to prepare an alternative for her by making a deal with Ryuen's supporters instead. {{Downplayed|Trope}} in that he suspected that was her course of action to begin with.

* TheFriendsWhoNeverHang: After a rumor about Maya hating Onodera is spread, Sōshi Miyamoto points out that the two of them have never been hanging out with just the two of them.

* FormalCharactersUseKeigo: She's a very polite girl who speaks in respectful ''keigo'' to whoever she is speaking to, including her classmates.
* HairOfGoldHeartOfGold: She has blonde hair and other than her initial dislike of [[spoiler: Kiyotaka]], she is a polite, honest, and responsible girl.
* HeelFaceTurn: While she is hardly a villain in the first place, she still is antagonistic to Kiyotaka when she first meets him. After [[spoiler:he defeats her without harming her]], she realizes that he's a decent guy, apologizes for her actions, and treats him as a friend afterward.
* JerkassToOne: Tsubasa is a very polite and goodhearted girl, but she's antagonistic towards Kiyotaka, to the point of [[spoiler:wanting to get him expelled]], because [[spoiler:she blames him for the suicide of her friend Eiichirō]].
* MisplacedRetribution: She blames Kiyotaka for [[spoiler: Eiichirō's suicide, despite the fact that Kiyotaka couldn't have possibly known that him escaping the White Room would result in such a horrible event.]]
* MoralityPet: Compared to all the people who have tried messing with Kiyotaka, he doesn't try to hurt Tsubasa [[spoiler:when they fight]] and is always polite to her. It helps that she's actually decent and polite, and [[spoiler: Kiyotaka realizes that Tsukishiro is manipulating her]].
* PlatonicLifePartners: With her ChildhoodFriend [[spoiler:Eiichirō]]. They share a very close bond without any romance between them.
* {{Revenge}}: [[spoiler:Eiichirō's suicide greatly affected Tsubasa to the point that she attended the Advanced Nurturing Academy in ''Year 2'' to exact revenge on Kiyotaka by getting him expelled.]]
* SheatheYourSword: [[spoiler: This is the approach Kiyotaka takes when fighting her in Year 2 Volume 3, as he opts to simply dodge all her attacks and let her tire herself out despite being fully capable of delivering a CurbStompBattle.]]

[[quoteright:250:https://static.tvtropes.org/pmwiki/pub/images/kouhei_katsuragi_anime.png]]

An intelligent student who worked very hard to reach Class 1-A and became one of its representatives.

* FaceOfAThug: He is described as looking very intimidating, but is actually incredibly intelligent, well-spoken, and polite.
* GracefulLoser: He intended to be this in the Expulsion Test, recognizing Class A's failures with him in charge made him the most likely target, even smiling in resignation when the polls were going to be announced. However, to his surprise and horror, the one with the most negative votes instead ends up being [[spoiler:his NumberTwo, with [[ManipulativeBitch Sakayanagi]] making it so he'd stay in acknowledgment of his talent, while deriding his friend for lacking it.]]
* NiceGuy: He's very serious and comes across as somewhat aloof, but he's a kind and polite guy.
* NobleDemon: Not that he's evil by any means, but belonging to Class A, he technically has an antagonistic role; despite this, he strikes up a genuine friendship with Ayanokji and ends up proving himself to be a reliable friend. For all his proud, serious, and somewhat haughty attitude, he is also shown to honorable and kind.
* PrematurelyBald: He's already bald at an age of a high school student.
* SixthRanger: [[spoiler:During the second year, he's transferred to the former Class C, becoming their new classmate.]]
* YoungerThanTheyLook: He's a first-year, but looks much older.

[[quoteright:175:https://static.tvtropes.org/pmwiki/pub/images/arisu_sakayanagi_anime.png]]

The main leader of Class-A. She is shown to be highly intelligent, as she seems to have very high knowledge of the school rules and the S-system. There is an intense rivalry between her and Ryuen alongside their respective classes as she thinks his challenges against Class A are interesting but ultimately futile.

* AntiVillain: Her fixation on Ayanakoji, as well as a lot of the dubious actions she makes in her efforts to get closer to and defeat him, are due to [[spoiler: sharing her father's concerns about places like [[BoardingSchoolOfHorrors the White Room]] becoming a widely practiced education facility, and so wants to defeat him to invalidate their use and prevent them becoming widespread.]]
* TheChessmaster: Unlike Ryuen who uses a direct approach, she prefers more subtle ways. She's even seen playing chess against herself.
* ChessMotifs: In the anime adaptation, the game of chess becomes her IconicItem even more so than in the light novel: not only is it her fateful first one-on-one battle against Kiyotaka Ayanokoji and she describes the school as her own chessboard with her own pawns, she's also shown playing chess all the way back in Season 1 while the opening of the third season, which focuses on her and Ayanokoji, uses a heavy chess theme.
* ClassyCane: She walks around with a cane that makes her look classy.
* ConnectedAllAlong: A bit of an odd case due to the encounter being [[spoiler:entirely one-sided, with her seeing Ayanokouji when her father brought her to the White Room 8 years prior.]] But the meeting seems to have stuck with her, considering she can recall the amount of time she last saw him, down to the number of days.
* EvilIsPetty: Granted, [[AssholeVictim the person she went after was hardly underserving of it]], but the entire reason she used Yamauchi as a pawn in her scheme to ensure Ayanakoji wasn't expelled before promptly backstabbing him was because he accidentally but unapologetically knocked her over and [[NeverMyFault derided her as clumsy for it.]]
* FormalCharactersUseKeigo: She's a polite and refined girl who uses ''keigo'' in her speech with everyone.
* FriendlyEnemy: Is very friendly and explicitly states that she holds no ill will towards Ayanokouji despite her goal of "burying" him. This is because she knows that is exactly what he wants.
* GeniusCripple: She's physically crippled due to her heart condition, causing her to walk with a crane. She's also one of the smartest characters in the entire franchise.
* GracefulLoser: After she wins a match against Kiyotaka, she finds out she only won because of Tsukishiro's meddling. In the aftermath, she challenges Kitoyaka to a rematch and he defeats her fair and square, a result which she gracefully accepts.
* HeightAngst: Apparently [[HeightInsult using her small stature to insult her]] really grinds her gears.
* HimeCut: She has blunt bangs, cheek-length sidelocks, and shoulder-length straight hair. Her hairstyle fits her refined behavior as well as her status as the chairman's daughter.
* IconicItem: Both her ClassyCane, which she needs to walk, and the game of chess in general, which is often used to [[SmartPeoplePlayChess point out that her intelligence]].
* ItsPersonal: With Yamauchi of all people! This was because he tripped her when he didn't notice her and was half-assed in his apology, but not before talking loudly enough for Arisu to hear that she is cute but clumsy. This leads to her [[spoiler:orchestrating his expulsion.]]
* TheRival:
** Seems to have a rivalry with Ryuen for supremacy.
** More directly in a rivalry with Ayanokouji, though an odd example because it is only because he wants her to be one and defeat him.
* ShorterMeansSmarter: She's one of the smallest students of her grade and one of the top students.
* SignatureHeadgear: She wears a black beret on her head, which she's rarely seen without.
* SmartPeoplePlayChess: She's among the most intelligent characters in the series and she's often seen playing chess.
* SmugSmiler: She almost never takes her arrogant smile off her face.
* VillainousCrush: She seems to have an attraction for Ayanokouji, who is her enemy.
* WorthyOpponent: She considers Ayanokouji as an opponent she would like to bring down with everything she has.
* {{Yandere}}: Shows shades of this in a short story from her perspective. [[spoiler:She apparently always dreams about Ayanokouji, thinks about him all the time, and expresses a desire to make him hers (whether that's romantically, or literally is a bit ambiguous). She also internally mentions how she doesn't care about Class A's position at all, only caring about how she can directly defeat Ayanokouji to fulfill his wish.]]

A student who acts as the right-hand woman for Arisu.

* GracefulLoser: She takes [[spoiler:being chosen for expulsion by Arisu]] surprisingly well and rather than convince her to let her stay, Kamuro tells her to find a good replacement for her.
* HonorAmongThieves: She asks Kitoyaka to defend Honami from Arisu's attempts to defame her. Her reason is that Honami also has a past as a shoplifter like her and she doesn't want to see her ruined when Honami is a truly good person.
* MaleGaze: During her first one-on-one conversation with Kiyotaka Ayanokoji while in his room, the anime adaptation features several shots focusing on her butt, thighs, and legs.
* NumberTwo: She's this to [[TheChessmaster Arisu Sakayanagi]], even more so than Hasimoto. It's to the point that Arisu herself recognizes her as her best friend.
* OnlyFriend: Sakayanagi recognizes her as her first and only friend.
* PerpetualFrowner: She's always depicted sporting a surly frown.
* PutOnABus: [[spoiler:She's expelled during her second year.]]
* ReformedCriminal: Sort of. She used to be a habitual shoplifter until Arisu caught her red-handed. Instead of ratting her out, Arisu forced her to become her assistant, giving her so much work to do that she doesn't have time for shoplifting anymore.
* SatelliteCharacter: She's usually seen together with Arisu and follows her orders.
* StalkerWithoutACrush: She stalks students from other classes to gain information for Arisu.
* StickyFingers: She has a bad habit of shoplifting.

A student who has connections with other classes.

* TheLeader: Although he's not the official leader of his group during Mixed Training Camp, Kiyotaka points out in his thoughts that he has incredible leadership skills. He's able to defuse an argument between his teammates with just the right words and making them feel more unified in obtaining their goal.
* NumberTwo: To [[TheChessmaster Arisu Sakayanagi]], alongside Kamuro. At least before he [[spoiler:betrayed Class A.]]
* StalkerWithoutACrush: He stalks students from other classes to gain information for Arisu.

* IconicItem: His gloves, with the gesture of putting them on in a threatening manner as he's about to fight his opponents being equally as iconic part of his character.
* NumberTwo: He acts as this for Arisu, albeit he's seen in this role less often than Kamuro and Hashimoto.
* SatelliteCharacter: Much like Kamuro, he's characterized mostly by his devotion to Arisu Sakayanagi and spends majority of his screentime working for her.
* UndyingLoyalty: On a promotional Akihabara poster, he proclaims that his wish going into his second year is to protect his class with his life.
* YoungerThanHeLooks: He's a high-school student but looks much older.

A student who acts as the right-hand man for Katsuragi.

* DecoyLeader: Has role of his class's captain during the first island exam. Rather than due to leadership skills, the role was chosen mostly to mislead the other classes and make guessing Class A's leader harder, since most would expect Katsuragi.
* NumberTwo: He acts as this to Kohei Katsuragi, being his most loyal follower, even when Arisu's faction is gaining popularity.
* OnlyFriend: He respects Kohei as a leader and is the only known Class A student who remained on Katsuragi's side even after his deal with Class C only got Class A the third place in Deserted Island Special Test.
* PutOnABus: [[spoiler:He's expelled during the Class Poll special exam as Sakayanagi would rather keep Katsuragi around for his usefulness.]]

[[quoteright:250:https://static.tvtropes.org/pmwiki/pub/images/manabu_horikita_anime.png]]

Suzune's older brother and the school's student council president. He resents Suzune for being in the lowest class, claiming that her presence threatens his reputation in the student council.

* AcademicAthlete: He's one of the best pupils of the school, and also an excellent sportsman.
* TheAce: The number of students who can compete with him, be it in brains or brawn, is abysmal.
* AloofBigBrother: Manabu is very distant from his sister, as seen by his unamused reaction when Suzune tells him she is in this school to gain his approval. {{Subverted|Trope}} as it turns out he does care for Suzune's growth and well-being, and he helps her when possible. The reason he is so harsh with her is because Suzune stunts her own growth by trying too hard to emulate him. When Suzune finally gets over that in volume 11.5,this trope fades and he gives her a genuine smile along with a SoProudOfYou speech.
* AlwaysSomeoneBetter: To many students, but especially Suzune (who wants to emulate him) and Nagumo (a 2nd-year student set to become his successor). Even after dealing considerable damage to Manabu's class in volume 8, Nagumo remains unable to expel him and anyone in his class before they graduate, something which Nagumo playfully laments in volume 11.5.
* BenevolentBoss: Although stern and stoic, Manabu treats his subordinates in student council (even his personal resenter Nagumo) and his fellow Class 3-A students well, and he never shows anything less than respect for other students unless they are on the verge of breaking rules. He even lets his class take a significant loss in their private and class points to prevent the expulsion of Tachibana in volume 8, because he says his people are united.
* BigBrotherBully: When Ayanokouji first sees Suzune talking to him privately, all he sees and hears is her brother berating her and calling her a fool for choosing the same high school as him. He then holds one of her hands up and seems ready to hit her before Ayanokouji steps in. However, her behavior before the intervention suggests he's beaten her in the past.
* FatalFlaw: He has an admitted one to himself that bothers him throughout his school years: his lack of a true confidant with whom he can share his deepest and personal thoughts. After he graduates in volume 11.5, he tells Kiyotaka not to commit the same mistake.
* GeniusBruiser: He's the initial StudentCouncilPresident, and a fighter who can safely jump off the second floor and stand in the way of two factions of students.
* {{Hunk}}: He has excellent musculature as shown in episode 7 of the anime and in the manga, which only adds to the pluses of his handsome appearance.
* JerkassHasAPoint: For all his insulting of Suzune, she was truly mistaken in thinking isolating herself from her peers proves her independence since her loner act landed her in Class D and she eventually acknowledges that she has to be united with her classmates to go up in class ranks.
* LonelyAtTheTop: To a degree. His monologue in volume 8 gives an impression of this.
* ObliviousToLove: He doesn't seem to be aware of his secretary Tachibana's feelings for him.
* OddFriendship: With Kiyotaka. Despite their first encounter involving violence, Manabu is intrigued by Kiyotaka's hidden talents and treats him with considerably more respect than anyone else, especially compared to his treatment of Suzune. Notably, Manabu offers Kiyotaka a position in the student council, an offer which he rarely ever extends even to 2nd and 3rd-year students. On Kiyotaka's part, he respects Manabu as a legitimate senior and later on expresses willingness to form a give-and-take relationship with him after he steps down from the student council. When Manabu graduates in volume 11.5, Manabu asks Kiyotaka to see him off, and shares several pieces of advice including the importance of a confidant as well as making memories of oneself within the hearts of others, in a true Senpai-Kohai fashion.
* RulesLawyer: Fittingly as a student council president of an academy that lives by this trope, he is perfectly willing to use violence despite the school forbidding it, knowing it cannot be proven conclusively. However, he does respect the rules that the school puts in place to some degree, and disagrees with his successor Nagumo's intent to warp the rules into his own ideal school.
* PutOnABus: He graduates at the end of Kiyotaka's first year.
* TheStoic: Manabu shows composure in almost all situations, as long as it does not concern his sister.
* StopWorshippingMe: The reason why he's so aloof to his sister is to not want her to emulate him as much. It's justified as not only does it prove detrimental to Suzune's growth, but Manabu clearly has his own issues that would result in his current behavior.
* StudentCouncilPresident: He's the student council president, making him highly respected by the upper echelons of the school student society. He gets replaced by Miyabi Nagumo in the second half of the first-year saga.
* TallDarkAndHandsome: He is fairly tall, has dark hair much like his sister, and is undeniably good-looking. He also definitely fits the aloof image his appearance suggests.
* WorthyOpponent: Sees Kiyotaka as a promising freshman, and genuinely enjoys the rare times when they actually get to compete; Manabu even laughs in contentment when Kiyotaka tells him to give it his all just before their one-on-one running competition.
* WouldHitAGirl: Had Kiyotaka not intervened, Manabu would've physically beaten Suzune. Judging by Suzune's reaction, he had done so in the past whenever she tried to emulate him.

The Student Council Secretary, who is seen with the school's Student Council President Manabu and almost all the time has feelings for him.

* CannotSpitItOut: She's kept her feelings for Manabu a secret throughout their three years at school.
* CurtainsMatchTheWindows: She has purple hair and eyes.
* HeIsNotMyBoyfriend: She outright denies being Manabu's girlfriend while being too flustered by the question.
* NumberTwo: She acts as this for Manabu Horikita.
* PutOnABus: While she manages to avoid actually being expelled thanks to Manabu asking their classmates to use their points to save her, she still leaves the story regardless due to graduating at the end of Kiyotaka's first year.
* SatelliteCharacter: She's rarely seen away from Manabu's side and her characterization revolves around her devotion to him.
* TheScapegoat: She's blamed for her group failing to pass the Mixed Training Camp and therefore chosen for expulsion, all as a part of Nagumo's plan to screw over Manabu.
* SubordinateExcuse: She has an obvious crush on Manabu, which is the main reason she loyally serves him as his main underling.
* TargetedToHurtTheHero: Miyabi Nagumo engineers a plan to get Akane expelled during the Mixed Training Camp, just to hurt Manabu by making him lose his closest ally. Manabu has to sacrifice most of his class' points to save her from expulsion, which also works in Nagumo's favor.

[[quoteright:250:https://static.tvtropes.org/pmwiki/pub/images/miyabi_nagumo_anime.png]]

A 2nd year Class A student who succeeds Manabu Horikita as the Student Council President.

* EvilIsPetty: His method for trying to get Kiyotaka's attention is to have the third years stop and stare at him whenever he's around. While it is certainly an uncomfortable position to be in for most people, Kiyotaka is at worst annoyed by it.
* HateSink: He's a major antagonist, rules the school as a tyrant, and his strategies involve SadisticChoice and/or outright expulsions.
* AnOfferYouCantRefuse: Nagumo tries to make a deal with Honami to provide her with 4,043,019 private points. In exchange, Honami would have to date Nagumo. It was done to make sure Honami had enough points (20,000,000) so that she would not have to sacrifice a person to be expelled in the Class Poll special exam.
* SadisticChoice: His goal in the mountain training exam was to force one on Manabu. He intentionally has his underling, who served as leader of a group, underperform and designate Akane, Manabu's close confidant, as the group's weak link so that both of them would be expelled. This forces Manabu to choose between losing Akane or using up most of his class' points to prevent the expulsion and affect their standing. [[BenevolentBoss Manabu]] chooses the latter, declaring that he and his class will climb back up.
* ScrewTheRulesIHaveMoney: Ayanakoji speculates that he was able to talk his underling into a TakingYouWithMe gambit by offering to pool he and his associates points to prevent her from actually being expelled.
* StudentCouncilPresident: He takes the torch after Manabu Horikita.
* TargetedToHurtTheHero: This is what he does to try and challenge Manabu and later, Kiyotaka. Nagumo is willing to threaten to expel his "rival's" closest allies in order to draw them out.
* TyrantTakesTheHelm: Whereas Manabu was more of a ReasonableAuthorityFigure, Nagumo rules the student council through an iron fist and expels anyone who tries to oppose him.
* UnknownRival: Nagumo constantly tries to force Manabu into a showdown with him, but Manabu sees him as a nuisance rather than the WorthyOpponent Nagumo wants to be seen as. After Manabu graduates, this behavior extends to Kiyotaka.
* VillainWithGoodPublicity: He leads the school with an iron fist but has his entire grade united as his monolith. {{Downplayed|Trope}} in that there are still select few known exceptions and students outside of his grade don't tend to view him in high regard. It may also be assumed that some students are only on his side because he had promised to hold a lottery to graduate from Class A, randomly selecting students who paid for the chance with their private points.

A female student from 2nd year Class A. She is close to Miyabi Nagumo, but unlike her fellow second years, she does not idolize him despite being in the same class.

* FlowersOfFemininity: She's a GirlyGirl wearing a sunflower hairpin on the right side of her hair.
* IconicItem: Her amulet, which she lost during Mixed Training Camp, allowing her to meet Ayanokoji.
* SexySweaterGirl: She wears a form-fitting pink sweater over her school uniform, accentuating her breasts.
* SmallRoleBigImpact: She has a minor role, but she's the one who informs Kiyotaka Ayanokoji that Honami Ichinose intends to let Miyabi Nagumo date her in exchange for enough private points to buy an expelled student back, which allows Kiyotaka to prepare an alternative for her by making a deal with Ryuen's supporters instead. {{Downplayed|Trope}} in that he suspected that was her course of action to begin with.

[[quoteright:270:https://static.tvtropes.org/pmwiki/pub/images/honami_ichinose_anime.png]]

The Class Representative of Class-B, and a very kind, helpful, and selfless individual. She is one of the top students in her class and is very much admired and respected.

* AdaptationDyeJob: Her hair is pink in the light novel's colored art, but the anime makes her a peach blonde instead.
* AllLovingHero: She doesn't have a mean bone in her body, is very selfless and helpful, and just wants to maintain peace between higher and lower-ranked classes.
* BeingGoodSucks: An unfortunate consequence of her good nature in the later volumes is that Ichinose can't make hard choices or use underhanded tricks to get ahead of the other classes. As the gap between Class B, Class C, and Class D closes [[spoiler: Kanzaki]] begins to criticize her for it.
* BelatedLoveEpiphany: [[spoiler:By the time she realizes her deep feelings for Kiyotaka by the 2nd year Island Arc, he is already dating Kei. Despite trying to give up on him at first, she eventually just accepts that she still loves him, and declares her intent to win him over]].
* BuxomBeautyStandard: Her large breasts attract a lot of attention from guys and envy from girls, namely Suzune.
* CatharticCrying: Turns out the reason why she could stand up to Arisu's accusations and confess her past shoplifting crime to her classmates was because Kiyotaka had already confronted her about her past guilt beforehand, causing her to break down in tears and let out everything she had been holding back since the rumours of her being a criminal started.
* ClassPrincess: She's the top student of her class and is admired and respected by everyone, while also being genuinely kind and helpful to others.
* DudeMagnet: She's noted to be popular, which incurs Suzune's jealousy.
* EvenTheGirlsWantHer: One of her classmates even says she loves her.
* ExtremeDoormat: She wants to avoid conflict with other classes as much as possible. Even when Arisu starts spreading vile rumors about her and forces her to face terrible harassment, Honami refuses to do anything to defend her innocence and tries to endure the slander to not drag her class into a conflict. Later on, when Ryuen beats her class in an exam by using methods that range from reckless to illegal, she refuses to complain about it to the school, preferring to view the defeat as her own fault for failing to predict and adapt to his tactics. Ryuen later admits that he took Honami being too much of "a goody two-shoes" into account when coming up with the strategy.
* {{Foil}}:
** To Ayanokouji. She has an immensely good heart, is genuinely altruistic and people-oriented, and loves helping others, while Ayanokouji is purely task-oriented: he ''does'' help others, but only for personal gain, and has no qualms using them as tools.
** To Kushida, who really is a BitchInSheepsClothing, as her nature isn't actually kind-hearted, but actually pretty selfish and manipulative.
** To Ryuen, who is her exact opposite, being a selfish, power-hungry, petty, violent and vicious {{Jerkass}}. Honami is humble, selfless, a pacifist and a total sweetheart.
* GenkiGirl: She's a ray of sunshine with a cheerful, optimistic, and energetic personality.
* GoodIsNotDumb: Definitely not. Her kind heart should not be mistaken for her being a pushover or a {{ditz}}, and her personality isn't weak by any means.
* HairOfGoldHeartOfGold: She has peach blonde hair in the anime, and is likely the most kind-hearted and selfless character in the series.
* TheHeart: She keeps her class united, being very intended in making sure they all graduate together, and they all trust her with their points.
* {{Hikikomori}}: In her last year of middle school, she stopped going to school and shut herself in her bedroom for six months out of shame of having betrayed her mother's trust when she stole a hairclip for her younger sister. She came out of her reclusion when her mother asked her to go to high school and start over.
* HumbleHero: Despite her skills, she's not boastful and arrogant at all.
* IdealistVsPragmatist: The Idealist to Kanzaki's Pragmatist. Honami refuses to use dirty tricks or to allow her classmates to be expelled, even if it means having to constantly fight an uphill battle.
* KnightInSourArmor: [[spoiler:She eventually has to concede that her idealistic methods simply aren't getting results, and adopts a [[IDidWhatIHadtoDo somewhat more pragmatic attitude]], while still holding on to her refusal to let anyone in her class be expelled.]]
* MsFanservice: She's possibly the most well-developed girl in her grade and was shown wearing a bikini, as well as just her panties while getting a massage. She's also shown sunbathing on a [[https://you-zitsu.fandom.com/wiki/File:BD_DVD_Season_2_Kadokawa_Store_bonus.jpg Blu-ray/DVD Season 2 Kadokawa store bonus]].
* MyGreatestFailure: When she was in middle school, her mother was hospitalized due to overworking herself trying to save money for her younger sister's birthday gift. Honami then decided to try and get the present herself, but her sister had asked for a pricey limited edition hairclip that she couldn't possibly buy. Out of desperation, Honami stole the hairclip and gave it to her sister, but her mother realized what she had done and made her go back to the store to return it. While the shop owners forgave Honami and didn't press charges against her, she still felt guilty and ashamed for betraying her mother's and sister's trust in her. To start over and hopefully earn back her family's trust, she came to the Advanced Nurturing High School and tried to be a good leader for Class B. She begins to get over her feelings of guilt when she confesses her crime to her classmates, and they don't blame her and even sympathize with her.
* NiceGirl: She's always helpful to others and has the best intentions at heart.
* RoseHairedSweetie: She's pink-haired in the light novels (and a peach blonde in the anime). She's the sweetest girl in the cast, being the only one who's outright kind without a mean streak.
* SmarterThanYouLook: Proves herself to be much more clever than she appears at first glance, and is also a good student.
* TheTease: She likes to flirt with Kiyotaka.
* TokenGoodTeammate: Out of the main characters in the series, Honami is definitely the kindest, and doesn't have antiheroic qualities.
* UnknowinglyInLove: She starts developing romantic feelings for Kitoyaka as of volume 9. Later at volume 10, these feelings become more evident, but she's still oblivious about it.
* WideEyedIdealist: Honami wants to create a peaceful and friendly environment in her class, and she's determined to make sure they all graduate together without letting anyone get expelled. Unfortunately, her ideals are frequently challenged by the school's harsh system that ''encourages'' students who underperform or are a hindrance to their classmates to be expelled, and force the class to sacrifice a high number of points to protect their classmates from expulsion.

[[quoteright:250:https://static.tvtropes.org/pmwiki/pub/images/kakeru_ryen_anime.png]]

A student who has a reputation for being a feared delinquent, where he rules the class like a mafia boss and has a group of henchmen who do his dirty work.

* AdaptationalCurves: He's even more muscular in the anime adaptation.
* AdaptationalHairstyleChange: {{Downplayed|Trope}} in the anime adaptation, where Ryuen started with longer shoulder-length hair than in the light novel and manga.
* AdaptationalHeroism: {{Downplayed|Trope}}. The anime adaptation doesn't paint him as outright heroic by any means. However, it cuts the fact that he poisoned Class B students to have an advantage in the Event Selection Exam. While several students discuss in the final episode of the third season that he resorted to underhanded methods, an anime-only viewer would assume they're just referring to choosing [[MusclesAreMeaningful Albert Yamada]] for a judo competition.
* AlwaysSomeoneBetter: Ryuen's inflated ego stems from his assumption that he's smarter and stronger than everyone else in school and that there's nothing he fears. Then he meets Kiyotaka Ayanokoji, who proves to him beyond a shadow of a doubt that he's dead wrong on all three counts.
* AmbitionIsEvil: He wishes to ascend in the class ranks, and unlike Suzune, he intends to do it by crushing all other classes while being as ridiculously sadistic and inhumane as he thinks he can get away with, committing the most heinous crimes just short of rape and murder.
* BreakTheHaughty: Volume 7 has him completely beaten, with his right-hand students taken out by Kiyotaka and Ryuen himself [[NoHoldsBarredBeatdown getting the daylights punched out of him]]. But what really breaks him isn't this humiliating defeat, it's the fact that Kiyotaka can do this without even [[TranquilFury batting an eye]] and hold no emotions towards him at all. With this, Kiyotaka basically tells Ryuen in brutal, no-uncertain terms that the former sees the latter as nothing but a puny gnat far beneath his level.
* TheBully: He makes it a personal hobby of his to bully and degrade the students of Class D.
* BullyingADragon: He tries to pick a fight with Ayanokoji when the latter reveals he was the true mastermind who plotted his downfall, only to learn the hard way that there's a ''large'' gap between them not just in intellect, but physical strength too.
* DefeatMeansRespect: Not quite "friendship", but after being humbled and broken by Kiyotaka, Ryuen allows himself to be used as one of Kiyotaka's pawns in a symbolic gesture of deference.
* {{Determinator}}: This was how he was able to make Albert submit to him. While Albert was stronger and beat up Ryuen in their first fight, Ryuen refused to give up and continued jumping Albert and going after him relentlessly until Albert finally gave up and submitted to Ryuen.
* DickDastardlyStopsToCheat: For better or for worse he is Class C's leader and vowed to take them all to Class A. Considering his intelligence he might have been able to put up a good fight, but his obsession with going out of his way to humiliate his opponents eventually starts to fall apart around him as [[ShutUpHannibal more people start calling him out on his bullshit]].
* EstablishingCharacterMoment: First introduced provoking Sudo into attacking him while he had backup.
* FatalFlaw: [[{{Sadist}} Sadism]]. He doesn't want to just beat his opponents; he wants to utterly crush them in body and spirit. When his opponent is someone apathetic such as Koenji, Sakayanagi, or Ayanokoji, he loses his cool at not being able to control the situation.
* FreudianExcuse: From what little can be seen of his past shows that he never really had a good upbringing, and it influences his arrogant and violent behavior in the present time.
* GracefulLoser: Surprisingly enough, he accepts his crushing defeat at Ayanokoji's hands without fuss, and has no qualms about acknowledging the man as his superior.
* HateSink: Everything this scumbag does from the moment he first steps onscreen is to be as needlessly cruel and unlikable as humanly possible, doing everything he can to make the other students' lives miserable and without even a speck of remorse. This portrayal lasts up until Chapter 7 where Ryuen ends up so thoroughly defeated that afterward, he starts to show bits of redeemable qualities as he reflects on his past actions, subverting the trope.
* {{Hunk}}: Handsome and manly with a muscular body. His looks are about the only ''good'' thing about this otherwise repugnant excuse of a human being.
* {{Jerkass}}: He's utterly unpleasant and dismissive with everyone he interacts with.
* LaserGuidedKarma: Kakeru Ryuen loves nothing more than to harass, humiliate, and torment people just to fuel his sadistic ego. Then he comes face to face with a guy who vastly outclasses him, and the prick finally learns firsthand how it feels to be subjected to such physical and psychological brutality. By the time Ayanokoji's done thrashing him to kingdom come, Ryuen is left a broken, pathetic wretch, even worse off than all his past victims.
* MeanBoss: Everyone in Class C is afraid of him to some degree, and he treats them all as his minions at best or slaves at worst. When he exposes Manabe as a traitor, he hits her face against her desk and forces her to confess.
* OhCrap: When Ayanokoji has him beaten and at his mercy, Ryuen tries to keep up his bravado at first, but the moment he takes a long, hard look at his enemy's cold and uncaring expression, it finally sinks into him that he's hopelessly no match for this monster, and he's reduced to a whimpering, terrified mess as Kiyotaka pummels him to within an inch of his life.
* TheOnlyOneAllowedToDefeatYou: At the end of their first year, he proclaims to Kiyotaka Ayanokoji that if anyone's going to expel him, it's him.
* TheRival: Seems to have a rivalry with Sakayanagi for the supremacy of the school.
* SmugSnake: For all his arrogance and delusions of grandeur as a self-styled "master manipulator", Ryuen proves to be nothing but a lowly insect when put up against Kiyotaka Ayanokoji, a man who is leagues above him in every way.
* TheSociopath: A textbook example. Ryuen is cunning and intelligent but lacks empathy. His only form of pleasure is to inflict physical and mental pain upon others, seeing people's lives as nothing but toys for him to manipulate, break, and trample as he wishes. That said, following his brutal, soul-crushing loss to Kiyotaka, he begins to slowly grow out of the trope as he rethinks his way of life.
* TookALevelInKindness: Afte Kiyotaka defeats him, Ryuen loses a lot of his arrogance and sadism. He becomes much calmer and humble, and treats other people better compared to before.
* YouHaveFailedMe: A non-fatal version, but he still makes his hired muscle beat up the three students that he hired to frame Sudo for being tricked into withdrawing the complaint.

[[quoteright:250:https://static.tvtropes.org/pmwiki/pub/images/mio_ibuki_anime.png]]

A student who not only possesses excellent academic qualities, but her physical ability is also not to be underestimated. She is skilled in combat, having the knowledge of several martial skills that can rival those of many martial artists.

* AntiVillain: She works alongside Ryuen and is generally very underhanded, but she reveals that she wants to reach class A just as all the other students do, along with that she knows that she has an attitude problem and wishes she wouldn't be as nervous around people. Most importantly she hates Ryuen and only works with him because he's such a strong leader.
* DefeatMeansRespect: Just like Ryuen, she doesn't develop an outright friendship with Ayanokoji, but she grows more respectful of him following being beaten up by him, now being willing to ask him for help when necessary.
* DontYouDarePityMe: Does this when Airi, Kiyotaka, and Haruki find her sitting next to a tree on the island, with some obvious signs she's hurt. Despite claiming to be their enemy for this trip, they take her back to their camp, along with offering her some fruits they found.
* EveryoneHasStandards: She seems to be furious at Ryuen's methods, being especially disgusted with his ColdBloodedTorture of Kei.
* HiddenDepths: She is actually really into fortune-telling and is surprisingly self-aware about her faults.
* KickChick: Her fighting style resembles capoeira, which mainly involves kicks.
* TheMole: During the survival test at the island, Ryuen sends Ibuki to infiltrate Class D and steal their card from Suzune.
* ShipTease: With Kakeru Ryuuen. She's among his [[UndyingLoyalty most loyal subordinates]], she's visibly disappointed when he's thinking of dropping out following his defeat at the hands of Kiyotaka Ayanokoji to the point of acting like a disappointed girlfriend, and she gets flustered when Ryuen pins her to a pole after blocking her attacks and claims he's fond of her attitude.
* UndyingLoyalty: To Ryuen. She's one of his classmates who is loyal to him even after he's defeated by Kiyotaka, even asking Kiyotaka to save him from expulsion during the class poll.
* WoundedGazelleGambit: Ryuen beats her and separates her from the rest of Class C during the survival test, leading to Class D letting her stay at their camp out of sympathy. In reality, it was a setup from Ryuen and Ibuki is a spy sent to steal their card.

* NoodleIncident: According to his student database, he had some trouble with senior students in the past.

A student with a short temper and a rough personality. Ryuen uses him as an errand boy, but he respects Ryuen and always follows his orders. He's better at using his body than studying.

* AdaptationalVillainy: While still something of a jerk in the novels, the anime shows him [[WouldHitAGirl grabbing and threatening to hit Suzune]], when she confronts him about framing Sudo.

* AlphaBitch: She's the leader of the female bullies of Class C.

* TheBully: She and her gang make Kei into their bullying target.
* DisproportionateRetribution: Kei was rude for pushing Rika and then refusing to apologize for not noticing. However, Manabe and her posse take it too far when they keep bullying Kei over such a trivial incident, even delivering a NoHoldsBarredBeatdown after luring her into an isolated location.
* {{Jerkass}}: She's a cruel person who gets off on bullying people weaker than herself.
* KarmaHoudiniWarranty: She harasses Kei mercilessly, even physically assaulting her after setting her up.

* MoralMyopia: Manabe and her posse berate Kei for refusing to apologize for accidentally shoving their classmate Rika. However, they then take sadistic pleasure in seeing Kei tremble because her bullying triggers her TraumaButton, culminating in them beating her senseless for no real reason, yet they don't seem to acknowledge the way they abuse Kei is way worse than what Kei did when she pushed Rika unintentionally.
* PrideBeforeAFall: [[spoiler: She's very smug when it looks like Ryuen's going to be expelled, even taunting Ibuki that she'll be throwing a negative vote her way in absolute confidence. She ends up being completely blindsided when, through Ayanokoji brokering an alliance between Class B and Ryuen's remaining followers, she ends up being the one getting expelled, leaving her a broken mess.]]
* {{Sadist}}: She and her posse mercilessly bully Kei, getting a kick out of seeing Kei in tears when she starts breaking down.

* SkewedPriorities: She chooses to start bullying Kei in the middle of a test that could either benefit or hinder her class.
* TerribleTrio: She forms one with [[CoDragons Nanami Yabu and Saki Yamashita]]. The trio as a whole are just side antagonists who pale in comparison to [[MeanBoss Kakeru Ryuuen]].

* AdaptationalHairstyleChange: Aside from her hair described to be tied in a bun like a dango, Rika's physical appearance was never shown in the light novels.

* DisabledInTheAdaptation: She wears glasses in the anime, but isn't shown wearing them in the manga.
* LaughingMad: As Manabe pressures her to punish Kei, Rika starts to become hysterical in her physical assault of the latter while giving off cathartic laughs.

A student from Class C who won the protection point in Class Poll special exam and was initially the captain for the Event Selection Exam as a result, before Ryuen took over his role.

* AdaptationalAttractiveness: He's more attractive in the anime adaptation than on his light novel illustrations, mostly thanks to not having as pronounced of a big nose.
* DecoyLeader: He initially has the role of his class's captain for the Event Selection Exam thanks to having won a protection point during Class Poll special exam. However, on the day of the final exam, Ryuen replaces him, merely stating his absence as reason.

A Japanese history teacher and the assigned homeroom teacher of Class D.

* AdaptationalSkimpiness: Downplayed. Compared to the light novels and manga, the neckline of her shirt is much lower in the anime, showing off her impressive cleavage.
* BlackmailIsSuchAnUglyWord: Chabashira effectively says this to Ayanokouji, after revealing that she received a letter from the facility where Ayanokouji was raised, demanding that he be expelled. Chabashira makes an unveiled threat that she won't follow through with it but in exchange, Ayanokouji has to stop half-assing his performance in class.
** Volume 7 ends up [[SubvertedTrope subverting it]] as it's revealed that Ayanokouji was never in danger of being expelled. The teacher was using BlatantLies to gain Ayanokouji's compliance.
* DidntThinkThisThrough: Sae plans to blackmail Ayanokouji into helping her reach Class-A. However, Ayanokouji's father's presence at the school was more than enough evidence for Ayanokouji to know that Sae doesn't have any leverage against him.
* FreudianExcuse: A failure during her high school days left her as the apathetic uncaring woman she is at the start of the series, but it also explains why she is so determined to get to Class A once she realizes the potential of her students, especially Ayanokoji. Read MyGreatestFailure below for more details.
* HazyFeelTurn: The series starts with intentionally screwing her class over out of a petty grudge she holds for them, after blackmailing Ayanakoji she begins to take some interest in her class but this is only because she may be able to use him to get to class A. She still does help [[JerkWithAHeartOfJerk after they've broken the deal but it's still because she hopes to be able to rise to Class A.]]
* HotTeacher: Despite her stern personality, she's definitely attractive.
* MsFanservice: She's a HotTeacher who exposes her cleavage on regular basis.
* MyGreatestFailure: During her third year in high school [[spoiler: at the Advanced Nurturing Academy, she was a part of Class B, and she and her class were extremely close to Class A.

The issue has haunted her for 11 years.]]
* SecretKeeper: She guards Kiyotaka's secrets concerning his background.
* SinkOrSwimMentor: Taken to an absurd degree in the sense that she never reprimands or even warns her students of the consequences of their misbehavior. Chabashira and the school's mentality is that the students should be judged on their merit, so no warning on her part was needed since it should have been common sense.
* SmugSnake: When stripped of all her bravado, Sae is pretty weak and pathetic. Ayanokouji realizes that she has nothing to blackmail him against and decides to just ignore her threats much to Sae's dismay.
* SternTeacher: Despite her initial disdain towards Class D and their behavior, she praises them appropriately for performing well on a test, and is willing to take up on Kiyotaka's offer to raise Ken's failing mark in exchange for points.

* TheAlcoholic: First introduced nursing a hangover in front of her class.
* BitchInSheepsClothing: While Hoshinomiya is an easygoing teacher who gets along well with her class, she has a bit of a nasty streak. She blatantly asks Chabashira if she believes her students can actually get up to class A in an attempt to put her down. In volume 11 she passively threatens Ayanokoji when she realizes some of his potential.
* EveryoneWentToSchoolTogether: She and her co-worker, Chabashira, attended the Advanced Nurturing High School in their youth and are still friends in the present time.
* HotTeacher: Much like Chabashira, she's an attractive teacher. However, her appeal comes mostly from her cutesy appearance in her case.
* MaleGaze: Her debut appearance in the anime adaptation features a shot focusing on her breasts as she lies on the desk [[TheAlcoholic recovering from a hangover]].
* MsFanservice: She only has her butt covered by a blanket while getting a massage in the anime.

* ShipTease: She is a flirty kinda teacher, she teases and flirts with Kiyotaka in the original light novels.

* AbhorrentAdmirer: Airi is disgusted out of her mind by Kusuda and his predatory behavior towards her.

* AdaptationalUgliness: While his looks were never described in the light novel, he's rather plain-looking at best for a 30-40-something-year-old man in the anime.

* {{Ephebophile}}: He's an older man with an obsessive crush on the teenage Airi. He also seems to show interest in Kushida when meeting her for the first time.

[[folder:Atsuomi Ayanokouji ('''Spoiler Character''')]]
!!Professor Atsuomi Ayanokouji
!!!'''Voiced by:''' Creator/YasunoriMasutani (Japanese), Creator/ChristopherSabat (English)
[[quoteright:200:https://static.tvtropes.org/pmwiki/pub/images/atsuomi_ayanokouji_anime.png]]

Kiyotaka's father.

* AbusiveParents: The abusive parent part kicks in when we learn not only did he place Kiyotaka in the White Room, but the man was also responsible for the facility's founding in the first place. It's made clear from Kiyotaka's interaction with his father in volume 7, that the man sees his son as only a tool, unable to make any choice apart from the ones ''he'' has decided. Even the first time he saw his baby son, he did not show any paternal feelings towards him. Even if he did view Kiyotaka as family, Atsuomi thinks he would have just ignored him to focus on his ambitions. As he later reveals, he'll do ''anything'' to get Kiyotaka back into the White Room, even if it means [[OffingTheOffspring murdering him]] in the process.
* AlliterativeName: '''A'''tsuomi '''A'''yanokouji.
* AmbitionIsEvil: His unrelenting ambition is described to be his greatest asset, and unfortunately, that includes treating his own son as a tool to further his own goals and using his political connections to severely punish those who go against him. Volume Zero also reveals that he's willing to committing various shady and morally ambiguous acts (i.e. pandering to underage girls, bribery, espionage activities for hostile organizations, gaining connections with the ''Yakuza'' and lesser gangs, resorting to violent means, etc.) in order to get where he is.
* AmicableExes: He and Mika used to date for a good while before the events of Volume 0, but broke things off amicably.
* BookDumb: Atsuomi's academic history is described to be below average and is mentioned that he never graduated from a high-ranking university. Volume Zero reveals that if it weren't for Naoe-sensei's support and acknowledgement of Atsuomi's ambition, the latter's low academic history wouldn't have allowed him to get far in politics.
* DarkAndTroubledPast: Volume Zero reveals that Atsuomi's past wasn't an idyllic one. He grew up extremely poor in the countryside where his home consisted of a ''shack'' maintained by the neighbors, was abandoned by his father to be RaisedByGrandparents, has a low academic history, average physical strength, a subpar working effort, and the obvious implication that nobody around him believes he would amount to anything in life. This ends up playing a role in his extreme ambition to climb the social ladder and later establish the White Room.
* ADayInTheLimelight: Volume Zero has Atsuomi being the main viewpoint character for a good chunk of the narration and his origins revealed.
* {{Determinator}}: His ambition coupled with an unrelenting indomitable fighting spirit to achieve his goals is what allowed him to become the man he is today and someone that Kiyotaka feared the most.
* DisappearedDad: On the giving and receiving ends. Volume Zero reveals that his own father left him in the custody of his paternal grandparents and Atsuomi himself has no love towards Kiyotaka other than to use the latter as a tool to further his own ambitions to climb the political world.
* DrivenByEnvy: While his ambition is often stated to be his only noteworthy trait, Volume 0 reveals that his envy for those who lived high in society compared to his own extremely poor background is another driving force that strengthens it.
* EvilVirtues: Despite the more [[AmbitionIsEvil unscrupulous sides of it]], Atsuomi's ambition and determination to rise above his former low status does ring positive to many people of poor and challenging backgrounds (both InUniverse and out), never mind the proof of his worth to those of higher social status. For all of Kiyotaka's fear of his father, there's a deep underlying respect for the man's capabilities and Chairman Sakayanagi even compliments Atsuomi's ambition by describing his ability to move ''the entire country of Japan'' at one point.
* FromNobodyToNightmare: As narrated by Atsuomi in Volume Zero, he was born extremely poor in the countryside, abandoned by his father and [[RaisedByGrandparents left in the custody of his grandparents]], had a poor academic history and wasted most of his youth doing menial things. It was only when his relentless ambition caught the attention of a well-known politician that Atsuomi rose the political ladder, created the White Room, and [[TheDreaded someone that]] ''[[TheDreaded Kiyotaka]]'' [[TheDreaded is immensely wary of]]. Chairman Sakayanagi even describes to his daughter that despite Atsuomi's subpar qualities, he, at one point, was able to move ''the entire country of Japan'' with his relentless ambition.
* HeartIsAnAwesomePower: It's often mentioned and confirmed in Volume 0 that he's a RidiculouslyAverageGuy, with his only worthy trait is his unrelenting ambition and determination. As the series shows, along with Kiyotaka's fear of him despite his own academic and athletic abilities surpassing him, it took him very ''far'' in life.
* LastNameBasis: His first name wasn't revealed until Volume 0.
* RidiculouslyAverageGuy: During a flashback in Volume 11, Chairman Sakayanagi describes Atsuomi to be a commoner, who has never graduated from a top university or even possessed outstanding athleticism. His wife is also the same, and none of their relatives show any signs of remarkable abilities and talents.
* TheUnfettered: According to both Kiyotaka and Atsuomi's own narration in Volume 0, there's ''nothing'' he's unwilling to do to seize power and achieve his own ambitions.
* VillainProtagonist: Of Volume Zero, where shows Atsuomi's origins and the circumstances that led to him developing the White Room.

[[folder:Matsuo]]
!!Matsuo

Kiyotaka's butler.

* CoolOldGuy: Downplayed. He's mentioned to be nearly 60 before the start of the series and is described to be a NiceGuy and devoted single father to his son.
* DotingParent: He's a very doting father to his only child, Eiichirō, and made many sacrifices to make sure he had a good life.
* DrivenToSuicide: He burnt himself to death in order prevent his son, Eiichirō, from being further socially punished by Atsuomi for his choice of helping Kiyotaka [[spoiler:escape the White Room.]]
* FriendToAllChildren: According to Kiyotaka, Matsuo was exceptionally good at taking care of people, and any child would've liked him. It's implied that Matsuo's parental instincts are what led to him being willing to send Kiyotaka away from Atsuomi despite knowing the consequences.
* TheGhost: He never made a physical appearance in the series and is only mentioned by Kiyotaka, Atsuomi, and [[spoiler:Tsubasa]].
* GlamorousSingleMother: Gender-Inverted. He started off as a single parent who managed to secure a comfortable living condition for himself and his son as a butler for the Ayanokouji family. However, this becomes inverted after Matsuo allowed and helped Kiyotaka to apply to the [=ANHS=] to escape his father's control, Matsuo was severely punished by getting fired and having his reputation ruined to bar him from ever finding work to sustain his family.
* GoodParents: He was a loving and devoted father to his son Eiichirō.

* LawOfInverseFertility: According to Kiyotaka, Matsuo married young, but couldn't conceive a child until he was ''over 40''.
* NoFullNameGiven: His given name is never revealed.
* NoGoodDeedGoesUnpunished: [[spoiler:His act of helping Kiyotaka escape the White Room causes Atsuomi to bring his wrath down on him and his family by using his political influence to not only irreparably ruin Matsuo's reputation after firing him and leaving him unable to find a job, but he also did the same to his son, Eiichirō, by chasing out of a prestige private high school the latter ''just'' got into and barred any other attempts to apply elsewhere. While it's implied that Matsuo was "aware" of the consequences, he may not foresee just ''how'' severe the punishment was given to him by [[TheUnfettered Atsuomi]].]]
* ParentalSubstitute: Implied to serve as this for Kiyotaka as a butler, in contrast to Atsuomi's own views and treatment towards him.
* PosthumousCharacter: He's first mentioned in the main story when Atsuomi informs Kiyotaka of his suicide.
* ScrewTheRulesImDoingWhatsRight: [[spoiler:While he knew that things wouldn't bore well for himself and his son if he were to go against Atsuomi, Matsuo still helped Kiyotaka to achieve freedom by applying for the Advanced Nurturing High School simply out of kindness and sympathy for the latter's well being. Also, it's likely that Matsuo really didn't think just ''how'' bad of a punishment Atsuomi would inflict on him.]]
* SenselessSacrifice: [[spoiler:To prevent Atsuomi from further social harm to his son in retribution for helping Kiyotaka escape the White Room, Matsuo begged Atsuomi to leave his son alone by [[DrivenToSuicide burning himself alive]] in exchange. While Atsuomi, at least, honors Matsuo's last wish, the latter's sacrifice becomes AllForNothing as Year 2, Volume 3 reveals that Eiichirō also took his own life not long after.]]
** What makes this worse, is that [[spoiler:Volume 0's ending reveals that Atsuomi ''planned'' for Matsuo to help his son get away from him. This makes Matsuo and his son's tragic fate set in stone in retrospect.]]
* SmallRoleBigImpact: He was the one who allowed Kiyotaka to escape the White Room and enter the Advanced Nurturing High School to escape Atsuomi's influence.
* UnwittingPawn: [[spoiler:It's later revealed at the end of Volume 0 that Matsuo's successful attempt to help Kiyotaka was pre-planned by Atsuomi to manipulate Kiyotaka's growth.]]

[[folder:Eiichirō Matsuo]]
!!Eiichirō Matsuo

Matsuo's son.

* AmbiguousSituation: Since we only hear second-hand accounts from [[spoiler:Atsuomi and Tsubasa]], it's unknown if Eiichirō ever blamed Kiyotaka for the tragedy that befell his father and himself.
* ChildhoodFriends: He was friends with [[spoiler:Tsubasa]] when they were kids.
* DaddysGirl: Gender-inverted. He's very close to his father and is regarded as Matsuo's pride and joy.
* DespairEventHorizon: [[spoiler:Sadly, losing his father to a terrible suicide after having his future ruined by Atsuomi became too much for him to continue living.]]
* DetrimentalDetermination: Despite having his entry to the first prestigious private high school he applied to rejected by Atsuomi's political strings, he tries to bounce back by applying elsewhere. Unfortunately, Eiichirō's attempts are met with repeated failure due to the uphill battle against a man with a great amount of political power, denying him access to any success in life.
* DrivenToSuicide: [[spoiler:According to Tsubasa, he took his own life shortly after losing his father.]]
* TheDutifulSon: He's a dutiful son to his father by recognizing the sacrifices he made while growing up, leading to him studying diligently to achieve great things and repay his father's sacrifices.
* TheGhost: Like his father, Eiichirō is only mentioned.
* PlatonicLifePartners: With his ChildhoodFriend [[spoiler:Tsubasa]]. They share a very close bond without any romance between them.

* SmallRoleBigImpact: [[spoiler:His suicide greatly affected Tsubasa to the point that she attended the Advanced Nurturing Academy in ''Year 2'' to exact revenge on Kiyotaka by getting him expelled.]]
* StepfordSmiler: [[spoiler:Although he assures Tsubasa that things are still fine during Matsuo's funeral, it's clear that his father's suicide and his broken future Eiichirō greatly shattered whatever hope he has and killed himself not long after.]]
* TooGoodForThisSinfulEarth: From what little can be heard of him, Eiichirō was a NiceGuy whose very loyal and caring to his widower father and [[spoiler:childhood friend]]. [[spoiler:But due to his father being a political pawn to test Kiyotaka's growth, Eiichirō gets his future irrecoverably ruined as his father is forever brand to be incapable of finding work to financially sustain them, and any chance he gets at attending a prestigious high school is forever barred. Worse, losing his father in a horrific suicide by burning to death has broken whatever drive Eiichirō had left to continue living.]]

[[folder:Mika Ayanokouji ('''Spoiler Character''')]]
!!Mika Ayanokouji
[[quoteright:200:https://static.tvtropes.org/pmwiki/pub/images/mika_3.png]]

Kiyotaka's mother.

* AmbitionIsEvil: Similar to Atsuomi, Mika is also willing to commit unscrupulous acts to achieve her goals. At some point before her introduction in Volume 0, she calls in favor of Atsuomi to get rid of one of her co-workers to attain the #1 ranking girl in the cabaret business.
* AmicableExes: She and Atsuomi used to date for a good while before the events of Volume 0, but broke things off amicably.
* BookDumb: Similar to Atsuomi, she also never graduated from a high-ranking university, and Volume Zero revealed that she stopped her education after middle school and started working in the cabaret business.
* ChekhovsGunman: She's only mentioned by Chairman Sakayanagi in a flashback during Volume 11. It wasn't until Volume 0 that Mika made her first, and possibly only, physical appearance.
* ChosenConceptionPartner: In Volume Zero, it's revealed that Mika only married Atsuomi because of money, at the latter's offering, and the fact that he needed to sire a child for the White Room.
* TheFaceless: The only illustration of her in the light novel doesn't show her face.
* FemmeFatale: As part of her job in her cabaret business, Mika would often date and sleep with many men of high-ranking political and/or financial positions. The other part of her job also involves performing assassinations on political enemies.
* HatesBeingTouched: Despite her job in the cabaret business and willingness to date and sleep with certain men, she (understandably) really hates "pricks" who touch her without consent.
* InformedAttractiveness: She's described to be a beautiful woman, enough to be considered the 2nd ranking girl in the cabaret business until she called in favor of Atsuomi to get rid of her co-worker. It's also justified since her face is never shown in the illustrations.
* MissingMom: She remains seen throughout the series and her son doesn't seem to even know her. Turns out that soon after Kiyotaka's birth, Mika and Atsuomi divorced and she left to fulfill a mission. At the very least, Atsuomi allowed her to name their child Kiyotaka after one of the guys she's dated.
* NoFullNameGiven: She only goes by her given name, and later took up Atsuomi's surname in their temporary marriage.
* RidiculouslyAverageGuy: Gender-inverted. Like Atsuomi, she's also described to be a commoner, who has never graduated from a top university or even possessed outstanding athleticism, and none of their relatives show any signs of remarkable abilities and talents.
* WalkingSpoiler: It's hard to talk about Mika in any capacity without spoiling much of Kiyotaka's origins.

* WalkingTheEarth: [[spoiler:It's implied he went abroad from Japan after leaving the White Room.]]

* SoBeautifulItsACurse: She's one of the prettiest girls in Class D when she dolls herself up, even being a popular gravure idol. Unfortunately, her looks nearly makes her a victim of sexual assault from a creepy stalker, only being saved by Kiyotaka's arrival.
