History Characters / CipherAcademy

* GreatnessLooksLikeFailure: Ironically, due to her excellent speed, she initially has a reputation as the worst student in class: she's never been seen working on an assignment... because by the time any other student looks up from their desk, she's already solved it.

* CuteOversizedSleeves: Her sleeves are clearly too long for her. Together with the hair obscuring her eyes, it gives her a slightly pathetic and helpless look. [[spoiler:Once she [[ImportantHaircut cuts her hair]], she also rolls up her sleeves, signifying a newfound confidence and determination.]]

* SuperSpeed: Her biggest strength is that she can move ludicrously fast--thus allowing her, for example, to rapidly assemble several large jigsaw puzzles mixed together, in the blink of an eye. This is also why initially has a reputation as the worst student in class: she's never been seen working on an assignment... because by the time any other student looks up from their desk, she's already solved it.
** Her hands are also fast enough to turn raw wheat to ''flour'', simply by pounding it like a machine faster than the eyes can see. She also does other cooking-related stuff quickly and expertly.

* {{MacGyvering}}: Their speciality. Using nothing but a handsaw, sickle, and axe, they can make a handheld ''paper-processing mould'' in a very short amount of time, plus the ink.

* HasAType: Likes masculine girls. During his interrogation by Tayu, he said he considered Ms. Nikueda as his ideal woman, plus he liked Yukako's super-short boyish haircut. Still, he also blushes at (Anonymity)'s beauty just like most people.

* AmbiguousCriminalHistory: Iroha theorized she's this in the past, and Kogoe's info cards, which were at least partially reliable, mentioned Oboro's been in juvie.

* CharacterTic: Tends to prowl around upside-down. Under tabletops, from tree branches--you name it, she's hanging from it.

* AnimalEaredHeadband: Much like the other students in her class, she wears an animal-themed accessory on her head; in her case, a frilly cat-eared headband.

* CharacterTic: She appears to have a habit of spinning things on her finger.

* ExoticEyeDesigns: Her pupils are shaped like a sniper's reticle.

[[caption-width-right:739:Akina's crossword introduction, with Ms. Hossawa (right)]]

* CoolMask: Or ''mediocre'' mask, to be more precise. She's always seen wearing a medical face mask, seemingly with nothing special about it.

* TheVoiceless: Hasn't had a single dialogue in the manga so far, with her only making ''one sound'' within Ensa's imagination.
--> '''Imaginary!Akina:''' Nyo!

[[caption-width-right:250:Kakune's crossword introduction, while she dresses as Harukiri]]

* MediumAwareness: Although other characters occasionally break the fourth wall, she does it far more frequently. In [[https://static.tvtropes.org/pmwiki/pub/images/89de131e41ea2771c1288d10e417b774.jpg Chapter 16]], she interacts with the frame that usually introduces a puzzle--crushing it and spilling the "difficulty level indicator" stars into her hand, to symbolize her circumventing puzzles by cheating. In the beginning of Chapter 21, she is surprised that Iroha is suddenly way ahead of her in the poker game, and she wonders if she's somehow "skipped a chapter" since "last week's issue". In Chapter 22, she holds the narration box with her name in her fingers, and leans casually on a speech bubble.

* [[spoiler:NonStandardCharacterDesign: Her eyes are drawn in much greater detail than other characters, more in line with a shoujo manga character.]]

* CutAndPasteNote: In keeping with her fixation on anonymity, her "introduction crossword" is not filled with her handwriting, but with cut-out characters. Turns out to be her SignatureMove, since all her codes on paper is also written this way, even her solo chapter pages.

[[quoteright:500:https://static.tvtropes.org/pmwiki/pub/images/811e806e1370986b67d166df6ccbe003.jpg]]

Class 1-A's chief instructor, as well as the Health/PE teacher.

* AmazonianBeauty: ''The'' rippest character shown on-screen, though she manages to make it look not excessive.
* EyepatchOfPower: She wears an eyepatch, giving her a stern, no-nonsense appearance, although she's kinder than she seems.
* HotTeacher: To Iroha. He specifically mentions her as the ideal woman he'd like to date among all the cute girls in his class.
* ReasonableAuthorityFigure: Judging by grades, it's clear she has every reason to fail Iroha due to his terrible grades. However, she keeps giving him second chances against his obviously-better classmates so long as he creatively turns the situation around. However, she's also this to ''all'' students, meaning Iroha can sometimes be the victim of the advantages he's already granted.
* SternTeacher: As mentioned she is very serious in teaching, but also praises students quickly after they fulfill their assignements.

[[quoteright:457:https://static.tvtropes.org/pmwiki/pub/images/be08df3262f50608da9706c1d4e7fe0b.jpg]]

Class 1-C's chief instructor, she teaches Science class.

* TheAlcoholic: She arrives to the Class Leading Private meeting looking very drunk and holding a bottle of ''methanol'', though she inmediatly says it's only water, which makes her apparent drunkness confusing.
* BewareTheSillyOnes: Unreliable as she may look, she's still a teacher at Cipher Academy, with a [[https://static.tvtropes.org/pmwiki/pub/images/5a4dd4ed7b1fd77d6265c1c1bbd97464.jpg serious side]] she can bring out at the drop of a hat (even when drunk just moments earlier).
* {{Manchild}}: Her general attitude outside of class. Her students are allowed to talk back to her casually like they're friends of the same age, plus her sloppy and careless way of dressing (she's the only character wearing sandals in the academy). If (Anonimity) is nicknamed the "anything-goes student", then Junko's the "anything-goes teacher".
* TheNicknamer: Calls her class's leading private "Inval".

[[quoteright:395:https://static.tvtropes.org/pmwiki/pub/images/f688c18e6c87218a0a220913a469e5c9.jpg]]

Class 1-E chief instructor, she teaches Music/Art.

* [[spoiler:ConnectedAllAlong: She's the younger sister of Iroha's cheerleading club captain, Invicious. Iroha instantly recognized the same cheerleading maneuvers the latter used within Invalides.]]

* OnlySaneMan: Unlike her teammates who're very aggressive towards Class 1-A due to various reasons, she's very mild-mannered, polite, and didn't even bother provoking them in any way before her turn. She's always quietly skulking around and maintaining a neutral stance, even criticizing her leader and teammates sometimes when they go over the line.
* PaintingTheMedium: When first revealed, she emerges from under the tabletop, upside down. Her words in the speech bubbles are upside down too (as is the box introducing her name and role). When she stands up, her speech is written normally ([[BreakingTheFourthWall which Iroha notices and comments on]].)

* OneHeadTaller: Tonbo's quite tall [[https://static.tvtropes.org/pmwiki/pub/images/bba2182ed36bd4079d4d1548f7373edb.jpg compared to Iroha,]] but it's more glaring when she's standing [[https://static.tvtropes.org/pmwiki/pub/images/63b2cf8387a97d739d03366bac662c11.jpg next to Invalides,]] [[spoiler:her alliance partner during "Trilemma Capture List".]] The latter barely reached up to her ''waist''.

* WagerSlave: Early on, she gives Iroha a code-solving challenge, stating that he'll become her manservant if he fails. Iroha (or rather, a mysterious voice emitted from his glasses) turns it back on her by not just winning, but also persuading her that, since he won, ''she'' should become ''his'' servant. Unexpectedly, she obliges.

* GogglesDoSomethingUnusual: His glasses weapon makes it far easier for him to solve codes, by highlighting the relevant parts of the codes he is reading, and creating a floating display of the code characters which he can manipulate by hand.

[[quoteright:444:https://static.tvtropes.org/pmwiki/pub/images/b98d4d4f864e687c4b69248eb55e1715.jpg]]

* MismatchedEyes: She has heterochromia. Kakune, when impersonating her, used a colored contact lens to achieve the same effect.

* CoolMask: Or ''mediocre'' mask, to be more precise. She's always seen wearing a medical face mask.

* MyParentsAreDead: [[spoiler:Her birth parents, researchers for Kick-Attack Planning, were killed during a lethal weapon experiment--an accident which also injured Shutan and one which she carried to this day.]]

* DullEyesOfUnhappiness: [[spoiler:[[https://static.tvtropes.org/pmwiki/pub/images/aa09b7e88d73dba9662bb473f2c5dfde.jpg Sports these]] as a child after her father's scandal was exposed... by none other than ''herself''. She was more shaken by the horrible public reaction to her deed, having done so out of a strong sense of justice, than the fact she's sentencing her father to life imprisonment. She's gotten better at emoting as years past, but she's still [[TheStoic rather quiet and withdrawn.]]]]

* TeethClenchedTeamwork: With Iroha. She respected him well enough, but couldn't stand his overly-friendly demeanour to both his teammates (whom she judged he didn't knew very well) and opponents (whom she wanted to ''hurt'' most of the time). Iroha himself was still working through the trauma she caused him, thoguh he's always glad to have her by his side.

* DarkAndTroubledPast: He tells Kogoe that he had joined the Academy because he had "nowhere else to go". During the interrogation by Tayu, he also mentions that all his close friends are dead, that he has witnessed someone's death nine times, and that he's experienced child abuse. [[spoiler:He later recounts the story in more detail: his middle school cheerleading club was sent to visit a refugee camp, and all the members save for Iroha ended up killed by a gang of thieves.]]

** Her hands are also fast enough to turn raw wheat to ''flour'', simply by pounding it like a machine faster than the eyes can see.

* TheGlassesComeOff: Took off her glasses when Iroha accidentally (as usual) said the wrong thing, taking him on seriously without her glasses weapon.

* OnlySaneMan: Iroha, Ensa, and Kakune consider her this, much to her embarrassment.

[[quoteright:785:https://static.tvtropes.org/pmwiki/pub/images/e07f3b0e277dcc18fcf12d9a6786c6d9.jpg]]
[[caption-width-right:785:Tayu's crossword introduction]]

* AnimalDisguise: Wears a hyper-realistic bear suit... or so they claimed.
* LargeAndInCharge: Played with. They're the absolute biggest... ''creature'' seen in the manga, but they defer to Tonbo for major decision-making, for better or for worse.

* NonHumanSidekick: Serves as one for Class 1-B. They're also the most dedicated to acting out their AnimalMotifs, despite their insistence it's just a costume and [[{{Irony}} irritance at Iroha mistaking them for a real bear.]]
* SoreLoser: [[spoiler:Quokka was ''pissed'' when their team lost to Iroha for what they considered a 50-50 decision about who's better--between an offensive style which rewarded the most captives, or a defensive style which prioritized survival and minimizing captee. The fact it's an official decision by their teachers and Tonbo's attempt to explain and defuse the situation didn't help in the slightest, as they're still salty in the afterparty.]]
* StiffUpperLip: ''Very'' strict and stern in regards to manners, especially towards people who mistook them as a real bear or saying things carelessly. Not even their teachers' decisions were spared. He also chastises Iroha's habit of running in the corridors.
* TalkingAnimal: ''Appears'' to be so, but they claimed it's ''obviously'' just a costume to a shocked Iroha (and a suspicious crowd behind him).

* FragileSpeedster: Invalides is ''incredibly'' quick and agile, being a former gold medallist in child's gymnastics before skipping grades and joining Cipher Academy. [[spoiler:However, in her tag battle against Iroha, it's implied she lost despite him being a touch slower because of her weaker stamina and short stature, compared to him who's still a taller boy no matter how feminine he looks.]]

* BewareTheSillyOnes: Unreliable as she may look, she's still a teacher at Cipher Academy, with a serious side she can bring out at the drop of a hat (even when drunk just moments earlier).
* {{Manchild}}: Her general attitude outside of class. Her students are allowed to talk back to her casually like they're friends of the same age, plus her sloppy and careless way of dressing (she's the only character wearing sandals in the academy).

[[caption-width-right:784:The class, minus (Anonimity)]]

* HasAType: Likes masculine girls. During his interrogation by Tayu, he said he considered Ms. Nikueda as his ideal woman, plus he liked Yukako's super-short boyish haircut. Still, he also blushes at (Anonimity)'s beauty just like most people.
* HiddenDepths: Despite his lack of cryptographical experience and low self-esteem, he's got a natural aptitude for code-solving and is a empathetic leader. He's also a great dancer.

* NiceGuy: He is always positive and kind to everybody, he even was willing to forgive Tayu despite how close to a mental breakdown she left him.
* PowerCopying: [[spoiler:After he's elected as Class 1-A's leading private, he began to earnestly learn the ciphers and cracking methods his classmates excelled at, instead of relying on his own (rather futile) desperate self-study. He's now able to at least partially mimic (Anonimity)'s, Tayu's, Kyora's, and Oboro's specialities against various opponents in the class-wide competition.]]
* StarringSmurfette: He's the protagonist and the first guy to attended an other all-female school.

* InformedAbility: Yukako was highly-regarded by Kyora and her classmates, but was seen constantly losing against them like drawing with Iroha [[spoiler:and ''destroyed'' by (Anonimity), though she lost to (Anonimity) because she didn't see the latter's cheating coming.]] Her in-manga confirmed victory was against [[spoiler:Hannari, and that's actually just a personality test for Kyora rather than an outright duel.]]

* {{Catchphrase}}: She has two cathphrases, normally it's "A meeting by chance is preordained, as they say", the other "This too is some kind of resentment!" when angry.
* CuteOversizedSleeves: Her sleeves are clearly too long for her. Together with the hair obscuring her eyes, it gives her a slightly pathetic and helpless look.

* SheCleansUpNicely: Just once, and it's not exactly "cleaning up". Iroha just happened to glimpse what she really looked like under her BlindingBangs, and she's [[https://static.tvtropes.org/pmwiki/pub/images/e86ca5bf77c1c8b30018e61e41144a8c.jpg actually quite cute.]]
** [[spoiler:We get a better view of her face when she cut her hair short, as seen in the character image tab above.]]

[[caption-width-right:785:(Anonimity)'s crossword introduction]]

* BeautifulAllAlong: [[spoiler:Class 1-A's "orthodox beauty", and the only girl to stun Iroha with her looks alone in one glance. Makes it a great irony when Tayu mocked her CensorBox glasses weapon, implicitly calling her ugly... then [[https://static.tvtropes.org/pmwiki/pub/images/d865181298809ceb2f5d9f2f1bf06828.jpg (Anonimity) took her mask off.]]]]

--> '''(Anonimity):''' ''(being flung off the balcony of a treehouse)'' I like you too, okay?!

* MilitaryBrat: Her family's been in the militray for generations.

* InvincibleHero: Implied to be such, though she drew twice with Iroha--once when they first duelled and she forfeited, [[spoiler:the other when Iroha blatantly cheated (with a good dose of (Anonimity)'s bevy of tricks) but she let him win again.]] ''Nobody'' has beaten her head-on yet in this manga.

* LovedByAll: ''Everyone'' likes and admires her, even (Anonimity) (begrudgingly). It's notable she got the most early-stage votes during Class 1-A's class-leading private selection... by ''doing nothing'' (she even admitted this). In contrast, both Kyora and Iroha had to canvass for votes in the first few months they're enrolled ((Anonimity) didn't bother).

* AnimalEaredHeadband: Much like the other students in her class, she wears an animal-themed accessory on her head; in her case, a headband with moose antlers. [[spoiler:One of her antlers [[HatDamage snapped off]] in defeat after she lost against (Anonimity).]]

* WeakButSkilled: They're exceptional code breakers because of their ESP, [[spoiler:but given their very young average age and smaller bodies, Invalides was concerned a semi-physical exercise like "Trilemma Capture List" would put them at a disadvantage. And given ''[[GlassCannon Iroha]]'' was participating, plus athletic girls like Rokaku and (Anonimity) (and Quokka the ''bear''), she had a point.]]

* ColdBloodedTorture: Which makes them also TheDreaded, at least to (Anonimity). The "special mission" moniker implies they're being trained as special operative soldiers who're ordered to do off-the-book, inhumane things.

* ActuallyPrettyFunny: [[spoiler:The awkward interaction between Iroha and (Anonimity) made her slump against the treehouse wall, since she had no witty retort against them.]]

* TortureTechnician: As the leader of the "masked torturer" class, she's naturally this. [[spoiler:She tortured (Anonimity) quite sucessfully during "Trilemma Capture List", to the point the latter refused to come mingle with her in the afterparty.]]

* ManipulativeBitch: She constantly jumps between camps, betraying alliances and making new ones as she pleases. Amidst her lies, she also manipulates what information is given and choosing what words she speaks with to each individual so they'll move according to her wishes, playing with their feelings all the while. Iroha's just her latest victim--Kyora, (Anonimity), and Seppun are involved with her at some time in their lives.

[[quoteright:300:https://static.tvtropes.org/pmwiki/pub/images/96885848dfbc800244a7d96d41f45a9f.jpg]]

* StiffUpperLip: ''Very'' strict and stern, especially towards people who mistook them as a real bear or saying things carelessly. Not even their teachers' decisions were spared.

* [[spoiler:DeathSeeker: [[GracefulLoser When they lost,]] this was all they talked about. All in jest, of course.]]
* HandSeals: [[https://static.tvtropes.org/pmwiki/pub/images/18849a007fbeb78ec5e11727e81add8f.jpg Their tendency]] when cracking chiphers, as if "praying" for their opponents or "paying respect" to the dying message.

[[quoteright:785:https://static.tvtropes.org/pmwiki/pub/images/f55b45c5d6b490b4b4d3bf3c2cb53af2.jpg]]

The "undercover operations class". Their homeroom's taught by the Music teacher.

* CripplingOverspecialization: They excel at attaining personal information and scouting, which means any cipher containing these data is a cakewalk for them. They're also able to analyze and emulate others in a very short time. However, a regular, inorganic cipher such as the ones constantly given to Class 1-A stumps them.
* MasterOfDisguise: Their speciality, though the way they achieve it differs. For example, Shitai barely shows any disguising skill, but she holds an important frontwoman role so her friends can trick her opponents from behind the scenes. Byu specializes more in hiding and infiltrating than disguising herself. The rest are more straightforward.

[[quoteright:785:https://static.tvtropes.org/pmwiki/pub/images/8b00817085a3d0630d0a0a2808baf6e0.jpg]]

The leading private of Class 1-E. She is her team's General in the duel between Class 1-A and Class 1-E.

* ArchEnemy: Describes herself as Kyora's nemesis.
* {{Bifauxnen}}: She looks rather androgynous. During her first appearance, Iroha is initially unsure about her sex, and Shitai outright states that "it doesn't matter whether I'm a boy or a girl". However, later chapters explicitly refer to her as a "she".
* CrazyPrepared: Has ''two'' body doubles, even in the relatively safe confines of Cipher Academy.
* {{Expy}}: Looks a lot like Edmond Dantès from ''VideoGame/FateGrandOrder''.
* GracefulLoser: [[spoiler:Allowed Class 1-A to have the victory despite tying Kyora during the final cipher, having seen her ploy to sow discord between Yukako and Kyora failed, finally accepting Yukako's no longer a part of her group.]]
* MeaningfulName: Her name literally means "headless corpse" in Japanese.
* YoungerThanTheyLook: Her height, way of dress, and speech mannerism make her sound a lot older than she is, but she's of the same age as everyone else.
* YourTerroristsAreOurFreedomFighters: Her main conflict with Kyora. [[spoiler:Shitai saw herself and her group as "liberators" who aimed to take down Kick-Attack Planning because they viewed the company as immoral and lawless, while Kyora views them as a hateful terrorist organization who nearly destroyed her home and endangered her friends. Shitai, who was Yukako's oldest friend, despised Kyora for having tortured and brainwashed her (or so she thought), while Kyora, Yukako's current master and good friend, hated Shitai who's trying to drive a wedge between them. Her attack also caused Kyora's group, who focused on developing non-lethal weapons, to be disbanded, meaning she destroyed Kyora's life work due to a misunderstanding.]]

A student in class 1-E. She is her team's Forward in the duel between Class 1-A and Class 1-E.

* AlasPoorVillain: Her first (and last shown) match is against ''Tayu'', [[spoiler:who promptly sent her to the infirmary in seconds.]]
* InformedAttribute: She's hyped up to be a powerful cipher soldier, worth 200 million Morg according to Nohime's evaluations (twice that of Iroha's)... [[spoiler:[[CurbStompBattle but was taken out in one page by Tayu.]]]]
* MasterOfDisguise: As fitting for the "undercover operations" class. She makes her entrance during the duel by disguising herself as Iroha--managing to look almost exactly as him (save for a small detail).

[[caption-width-right:738:Yes, she's really upside-down. No, do not adjust your screen.]]

A student in class 1-E. She is her team's Second in the duel between Class 1-A and Class 1-E.

* CharacterTic: Tends to prowl around upside-down. Under tabletops, from tree branches--you name it, she's hanging from it.
* ExoticEyeDesigns: Her pupils are shaped like a sniper's reticle.
* GracefulLoser: [[spoiler:After losing to Shutan in the "Embracing and Matching" game, she takes her loss in stride, clapping and smiling for her opponent.]]
* HairAntennae: Has a single extremely long one (just as long as the rest of her hair) jutting out of her forehead, down in front of her face. It doesn't usually obstruct her vision given she's upside-down most of the time.
* OnlySaneMan: Unlike her teammates who're very aggressive towards Class 1-A due to various reasons, she's very mild-mannered, polite, and didn't even bother provoking them in any way before her turn. She's always quietly skulking around and maintaining a neutral stance, even criticizing her leader and teammates sometimes when they go over the line.
* PaintingTheMedium: When first revealed, she emerges from under the tabletop, upside down. Her words in the speech bubbles are upside down too (as is the box introducing her name and role). When she stands up, her speech is written normally ([[BreakingTheFourthWall which Iroha notices and comments on]].)
* RunningGag: Her habit of prowling underneath tabletops. [[spoiler:When Rokaku was making a table by hand, she even requested ''[[https://static.tvtropes.org/pmwiki/pub/images/38df1f2318562df5c9755f97a6419a99.jpg to test the its durability]]'' by trying to hang upside-down from it.]]
* StealthExpert: As fitting for the "undercover operations" class. [[spoiler:She makes her entrance during the duel by revealing she'd been hiding underneath the table, which Tayu had just been sitting at without noticing Byu's presence. It's also implied that Byu had been hiding under the furniture during various previous scenes in the manga, such as the duel between Iroha and Tayu.]]

[[folder:Ranbada Hanranbara]]
!!Ranbada Hanranbara

A student in class 1-E. Hannari's older twin sister.

* BodyDouble: Of a special sort: She acts as Shitai Kubinashi's ''body double's'' body double, [[https://static.tvtropes.org/pmwiki/pub/images/fd7464a5e7f55ae9deb0f1b092872c36.jpg hiding in Hannari's shadow.]]
* TheFaceless: Even more so than her younger sister. When acting as a body double, the only thing differentiating them is her black hair... though that's also likely just a wig, makeup, artificial colouring, etc. [[spoiler:She showed up for exactly ''one panel'' in the gradewide leader selection's afterparty, before returning to her sister's shadow.]]
* {{Ninja}}: Implied, given her ability to "hide in shadows". Literally.

Known as the "special mission class".

[[quoteright:740:https://static.tvtropes.org/pmwiki/pub/images/083a7edd925fe8d6026067c2b39e7308.jpg]]

* BrownBagMask: Their "uniform", similar to the AnimalMotifs practiced by Class 1-B.
* ColdBloodedTorture: Which makes them also TheDreaded, at least to (Anonimity). The "special mission" moniker implies they're being trained as special operative soldiers who're ordered to do off-the-book, inhumane things.
* TheFaceless: All of them wear burlap masks which only reveal their eyes and some of their longer hair.
* {{Hammerspace}}: Their ability to take out their blades out of nowhere seems to be unique to them compared to other classes.
* {{MacGyvering}}: Their speciality. Using nothing but a handsaw, sickle, and axe, they can make a handheld ''paper-processing mould'' in a very short amount of time, plus the ink.
* TheUnreveal: They ''insist'' on not taking their masks off, [[spoiler:to the point of standing idly like statues during parties with their food and drink untouched, lest people get a peek of their faces.]]

* ActuallyPrettyFunny: [[spoiler:The awkward interaction between Iroha and (Anonimity) made her slump against the treehouse wall, since she had no witty retort against them.]]
* TheFaceless: In her initial appearances, she wears a two-eared mask which completely hides her face, except for her eyes and for her long hair. Hers is uniquely decorated with the class-leading private medal attached to where her forehead should be.
* {{Hammerspace}}: To a more ridiculous extent than her classmates. Other than her sickle, she can also store ''two bundles of firewood'' and pull them out of thin air.
* TortureTechnician: As the leader of the "masked torturer" class, she's naturally this. [[spoiler:She tortured (Anonimity) quite sucessfully during "Trilemma Capture List", to the point the latter refused to come mingle with her in the afterparty.]]

[[caption-width-right:762:Kogoe in Vol. 2]]

A girl from the mysterious class "1-M", and the creator of the glasses weapons. She is a former technical advisor of Kick-Attack Planning, and enlists Iroha to help her get her hands on the 50 billion Morg hidden in the school. She has an animosity with Kyora Toshusai, who considers her a "warmonger".

* ArtificialIntelligence: Has a holographic AI partner named "CG" in the shape of an old male butler.
* ArtificialLimbs: She has a robotic left leg.
* CatchPhrase: "Can't say that too loudly though."
* ConsummateLiar: She lies as easily as breathing without batting an eye, usually by pretending to be someone's friend to let their guard down.
* ExactWords: Her claim to Iroha during their first meeting, about "ending half the wars in the world". She never said anything about ''the other half''--which is her true goal all along--nor did she describe from ''what number'' this "half" was. Like Kyora suspected, Kogoe can simply double all the wars in the world, then stopping half of ''that''.
* GadgeteerGenius: A genius inventor, who has created the glasses weapons. She also built her own smartphone, up to and including its ''communications satellite''.
* GotTheWholeWorldInMyHand: She wears a novelty fingerless glove, shaped like a globe--thus, symbolically, gripping the Earth whenever she closes her right hand.
* GreekChorus: She frequently provides fourth-wall breaking remarks at the bottom of the page, either commenting on the puzzles or telling obscure trivia.
* HeelFaceRevolvingDoor: Combined with ManipulativeBitch. Constantly 'makes friends' whom she immediately set to clash against one another, all for her vague wish of 'controlling profitable wars'. She's [[AffablyEvil genuinely affable]] to everyone, never taking things too negatively or seriously, but Kyora (and currently Iroha) is frustrated at how easily and blatantly she jumps between camps.
* {{Irony}}: Surprisingly, in a school specializing in breaking codes and solving ciphers, hers are very basic and easy to do (no more than 2-star when the ''average'' are 4-star ones), and she herself is below-average in code-breaking skill. Perhaps this is due to reliance on technology (and her glasses weapons), plus her preference to manipulating others instead of going to the front lines and breaking codes herself. She outright admitted her talent in this area was inferior to Iroha, his class's bottom-feeder at the time. The ciphers she presents the other students are also ''analog'', including the ones the school faculty requests her to design and make.
* ManipulativeBitch: She constantly jumps between camps, betraying alliances and making new ones as she pleases. Amidst her lies, she also manipulates what information is given and choosing what words she speaks with to each individual so they'll move according to her wishes, playing with their feelings all the while. Iroha's just her latest victim--Kyora, (Anonimity), and Seppun are involved with her at some time in their lives.
* MeaningfulName: Her name, Kogoe, means "frozen". She makes puns on it sometimes, and it is reflected in her crystalline-looking hair.
** [[spoiler:As part of her manipulative tendencies, Kyora noted she often tricked cipher soldiers and overworked them into a vegetative state. Kyora calls it "[to] freeze in ice".]]
* TeenGenius: In spite of being a teenager she is a genius inventor, has once been a technical expert in a global corporation, and holds the title of Professor.
* TrademarkFavoriteFood: Corndogs, which she eats at every occasion, even while sitting in a mysterious dark room with OminousMultipleScreens. In chapter 17, while every other character is labelled with their favorite variety of Baumkuchen, she is listed simply as "likes corndogs".
* TreacherousAdvisor: Maybe. She gets Iroha on her side by telling him she intends to acquire the 50 billion Morg to stop half of the wars in the world. However, at least if Kyora is to be believed, her true intent is to ''double'' the amount of wars instead--since the value of Morg is tied to the amount of global war damage.

[[quoteright:500:https://static.tvtropes.org/pmwiki/pub/images/811e806e1370986b67d166df6ccbe003.jpg]]

Class 1-A's chief instructor, as well as the Health/PE teacher.

* AmazonianBeauty: ''The'' rippest character shown on-screen, though she manages to make it look not excessive.
* EyepatchOfPower: She wears an eyepatch, giving her a stern, no-nonsense appearance, although she's kinder than she seems.
* HotTeacher: To Iroha. He specifically mentions her as the ideal woman he'd like to date among all the cute girls in his class.
* ReasonableAuthorityFigure: Judging by grades, it's clear she has every reason to fail Iroha due to his terrible grades. However, she keeps giving him second chances against his obviously-better classmates so long as he creatively turns the situation around. However, she's also this to ''all'' students, meaning Iroha can sometimes be the victim of the advantages he's already granted.
* SternTeacher: As mentioned she is very serious in teaching, but also praises students quickly after they fulfill their assignements.

Class 1-C's chief instructor, she teaches Science class.

* TheAlcoholic: She arrives to the Class Leading Private meeting looking very drunk and holding a bottle of ''methanol'', though she inmediatly says it's only water, which makes her apparent drunkness confusing.
* BewareTheSillyOnes: Unreliable as she may look, she's still a teacher at Cipher Academy, with a serious side she can bring out at the drop of a hat (even when drunk just moments earlier).
* {{Manchild}}: Her general attitude outside of class. Her students are allowed to talk back to her casually like they're friends of the same age, plus her sloppy and careless way of dressing (she's the only character wearing sandals in the academy).
* TheNicknamer: Calls her class's leading private "Inval".

Class 1-E chief instructor, she teaches Music/Art.

* InformedAbility: Yukako was highly-regarded by Kyora and her classmates, but was seen constantly losing against them like drawing with Iroha [[spoiler:and ''destroyed'' by (Anonimity), though she lost to (Anonimity) because she didn't see the latter's cheating coming.]] Her in-manga confirmed victory was against Hannari, and that's actually just a personality test for Kyora rather than an outright duel.

* LadyLooksLikeADude: You'd be justified for mistaking her for a lanky boy at first. Her first name, "Shitsuke", is also masculine.

* LovableAlphaBitch: She seems to be an enemy to Iroha early on, but her intentions are actually good--she seeks to stop Kogoe, who she believes intends to double the number of wars in the world--and she develops into an ally to Iroha after he proves himself. [[spoiler:She's also against her parents' business (and Kick-Attack Planning as a whole) to continuously develop lethal weapons and profit from deaths on the battlefield, choosing to focus on developing non-lethal weapons instead. This was what initially drew her to Kogoe and waht allowed the latter to manipulate her so, because Kogoe promised to develop the glasses weapon to solve conflicts non-lethally.]]

* BandageMummy: She is covered with bandages on her head and upper body, and wears an eyepatch. In spite of her apparent injuries, however, she usually seems cheerful. The bandages on her head and across her chest apparently are just for show (and to hide her hair accessory), [[spoiler:though some of her injuries were real and was a remnant of the lethal accident which killed her parents, such as her right eye and arms.]]

** [[spoiler:Her real reason for this pretense was so Kyora's parents wouldn't pressure her to continue her parents' work on developing lethal weapons--the very same weapons which ''killed'' them, playing the sympathy card.]]

* SelfMadeOrphan: [[spoiler:Non-lethal example. She personally uncovered her father's--then the Ministry of Defense--plot to overthrow the Japanese government, destroying his life and her family's public relationship with Kick-Attack Planning and the Iesuno family. She did this out of a personal sense of justice, but was emotionall scarred by the blowback she received, creating her current aloof personality.]]

* RunningGag: Her habit of prowling underneath tabletops. [[spoiler:She even requested ''[[https://static.tvtropes.org/pmwiki/pub/images/38df1f2318562df5c9755f97a6419a99.jpg to test the table's durability]]'' to Rokaku when she saw the latter making one by trying to hang upside-down from it.]]
