Kunugigaoka Junior High School Faculty
Gakuhou Asano
Gakuhou Asano (浅野 學峯 Asano Gakuhō)
Voiced by: Hideo Ishikawa (Japanese, vomic), Show Hayami (Japanese, TV anime), Chris Rager (English) Foreign VAs
The chairman (principal in the Viz and Funimation versions) of Kunugigaoka Junior High School.
- Abusive Dad: He punches Gakushuu in Chapter 123 / Season 2 Episode 12 after the latter deliberately provokes him while he's in a very emotional state of mind. It should be noted that Gakushuu's behavior towards him isn't that different either; he casually kicked a soccer ball towards his father's face earlier. Though Gakuho blocked the ball quite easily.
- The Ace: He's inhumanly skilled in a wide range of subjects and can teach any subject better than specialized teachers, to the point that several characters consider him a 'monster' not unlike Koro-sensei; it's made clear that he's in charge of a school only because of his devotion to education, and if he really wanted he could have become Prime Minister with ease. In fact, his first students nicknamed him "Mister Perfection" because of this.
- Animal Motifs: The centipede, symbolizing his creepy personality.
- Archnemesis Dad: He treats his son pretty much how you'd expect given how he treats his students. His son responds in kind. They have a lot in common. Although it's shown in Chapter 94 that the father is worse.
- Authority Equals Asskicking: This guy simultaneously took on four huge athletes (two of them being skilled martial artists) and wiped the floor with them, reducing them to bloody messes.
- Awesomeness by Analysis:
- He became an Instant Expert by intently watching and analyzing a black belt karate instructor over three days, learning his techniques and weaknesses.
- When actually meets Koro-sensei for the first time, he made a scaringly accurate assessment of the latter's true goals.
- Aw, Look! They Really Do Love Each Other: After he is basically brought back from the edge after Koro-sensei beats his workbook/grenade challenge, he and his son bond by talking about how much money they're going to make by suing each other. The last thing he says to Gakushuu is that they'll go file their complaints together.
- In the anime, something a little different happens. After losing the handbook-grenade game, Asano tells his son that suing him for domestic assault will never work because from then on, he'll continue to improve himself as a teacher... and a father. Aww!
- Badass Boast: After his defeat has been decided, amusingly enough."Koro-sensei, here's the thing about my education system; even if you destroyed the planet, it wouldn't matter at all. If the Earth didn't exist anymore, in the end that would make everyone equal...and my students wouldn't suffer any drawbacks. That... is one of the ideals of my educational philosophy."
- Beauty Is Bad: He's pretty good-looking for a middle-aged father. And he's a total prick.
- Big Bad: Of the school life side of the story. Every single problem Class 3-E faces originate with him.
- Break the Haughty: He lost his ultimate bet against Koro-Sensei. That said, it seems he has mellowed out, even if only a little.
- Broken Ace: Asano Sr. was a kind teacher who only wanted to educate his students into becoming good people, but became convinced that strength of will was the only virtue worth teaching after Ikeda, one of his three first cram-school students, committed suicide due to bullying.
- Compelling Voice: He can utterly dominate a person's will with nothing but a short conversation. See Mind Rape below.
- Creepy Centipedes: His Animal Motif. Visual imagery of centipedes are sometimes seen accompanying Asano Sr.'s actions, such as centipedes entering Takaoka's throat as Asano Sr. stuffs his termination letter up his gullet, or centipedes latching onto his students' heads as he teaches their class.
- Defiant to the End: Even after his final defeat he refuses to acknowledge that his philosophy of education is flawed, to the point of being willing to die for it as the rules of his own challenge demand.
- Empty Eyes: His eyes have no shine in them, presumably to show his ruthless and manipulative character.
- Establishing Character Moment: In his very first appearance, Asano explains that he wants to line up all the colors of a Rubik's cube quickly, using a method anyone can do. The answer? He simply jams a chisel in to take it apart and then put them back together. This moment shows that not only he's willing to use any method to win, but show how he's willing to brainwash his students to follow his dogmatic educational system.
- Even Evil Has Standards:
- Not even he agrees with Takaoka's sadistic Training from Hell methods, stating that while fear is an essential component of education, teachers that can only instill fear through violence are the worst kind, especially when it becomes counterproductive. In his own words, "I do not employ brutes".
- When the government exposes Koro-sensei as part of their final assassination plan, rather than take the easy way out and paint himself as a victim of the situation, Asano instead defends Koro-sensei's actions and manipulates reporters into writing defensive articles.
- Evil Counterpart: His backstory retroactively makes him one to Koro-sensei, which is made explicit in Chapter 126. He was originally an impossibly talented oddball teacher. Then after Ikeda's suicide, he became an impossibly talented oddball Sadist Teacher. Basically, he's what would happen if Koro-sensei went bad.
- Expository Hairstyle Change: Years ago, he wore his hair straight and limp, but after Ikeda's suicide made him Take a Level in Jerkass, he rearranged it into the harsh, spiky bangs that he has in the present, which remained even after his reconciliation with Koro-sensei, though it slightly limps down after he decides to step down in the epilogue and he reconnects with his old students, as to signify he's gotten back in touch with who he used to be even if he can never fully return to being that person.
- Fallen Hero: In Chapter 125 it is revealed that when he first started teaching, Asano Sr. was a hyper-competent and caring educator, not unlike Koro-sensei. However, after Ikeda committed suicide due to bullying, he began to question his own methods and concluded that Virtue Is Weakness. Over time, he became his own antithesis.
- Foil: He and Koro-sensei contrast each other greatly. Where Koro-sensei is a monster intent on destroying the world, Chairman Asano wants to improve the world through education. Yet strangely, Koro-sensei is goofy but kind, while Chairman Asano is strict and incredibly cruel.
- Follow in My Footsteps: His son Gakushuu is basically like him. They have a... disturbing relationship, with one intent on keeping the other as a corporate slave and the other treating his father like a pet.
- Freudian Excuse: He was originally a wonderful teacher who wanted his students to grow into good people. However, after Ikeda committed suicide due to bullying, he realized that being good was worthless and for his students to survive, they needed to be strong. It also turns out that Class 3-E's ramshackle campus was also the same cram school he used to teach in, which he disowned as a sign of weakness as his attitude changed.
- Graceful Loser: At the epilogue, the backlash over the revelation of his academic system forced Asano Sr. to resign, which he seems to have already anticipated, explaining the ease with which he accepted his fate. His last appearance shows him being visited by Nakai and Mori, the two surviving alumni of his first cram-school class (with Ikeda), who presumably help him pack his things up, as well as help him start a new life.
- Had to Be Sharp: After Ikeda's suicide, Asano Sr. resolved to become a tougher, more efficient teacher, even if at the cost of his moral bearing.
- Hoist by His Own Petard: His brainwashing tactics come back to bite him hard during the finals. Because of his brainwashing, Class 3-A got carried away by their bloodlust, which gave them tremendous intensity early on in the tests, but they couldn't keep it up through the end and ultimately slipped against Class 3-E, pretty much resulting in slow and steady winning the race.
- Honor Before Reason: Refuses to compromise his beliefs or education method, even with the world at risk or his own life. He would rather die by grenade than admit defeat.
- Hypocrite: He was horrified by the fact one of his students committed suicide because his self-esteem was destroyed by being constantly bullied, only to develop a school structure that promotes students to bully and destroy other students' self-esteem.
- The Insomniac: According to the Roll Book Time, he only sleeps on an average of 2 hours.
- Instant Expert: He surpassed a black belt in karate in three days after losing once, because he felt that losing twice would be like dying.
- It's All My Fault: He completely blames himself for Ikeda's suicide, as his failure to teach him to be strong is causes him to go off the deep end.
- Jerkass: Asano Sr. created a school system that encourages the entire student body to discriminate and humiliate the bottom 5%.
- Jerkass Has a Point: His cruelty is without measure and he manipulates the students, but aside from the discrimination and sabotage the lessons he's teaching do have their points, as he explains to Koro-sensei when he allowed Takebayashi to (temporarily) transfer out.
- Kill Steal: One of the reasons he fires Takaoka is to strip Class 3-E of their victory and to remind them that he is the one in charge.
- Knight of Cerebus: The usual comedy of the series is notably scaled back when Asano is around, and the tone darkens considerably thanks to his presence and actions. The baseball game in Episode 12 is a particularly good example of this.
- Leitmotif: "Asano Gakuhou"
, written and named after him. An ominous yet triumphant composition that often accompanies scenes of him scheming. - Manipulative Bastard:
- Anything he can do to ensure that his system works will be done, from personally teaching the content of the upcoming exams to all students except Class 3-E to hiring a Sadist Teacher to make sure Class 3-E's grades drop dramatically.
- And when said Sadist Teacher failed to live up to expectations e.g., beaten by Nagisa, he swiftly ejects them in order to deny the students the satisfaction of kicking him out.
- When he becomes the baseball team's substitute coach, he basically brainwashes them into a frenzy so they can crush Class 3-E in an exhibition match. Does the same thing when tutors Class 3-A for their second final exams.
- Meaningful Name: His first name contains the kanji for "learning" or "study" (學) and "peak" (峯), and he's the highest authority in Kunugigaoka Junior High School.
- Mind Rape: We never get to see the particulars, but a short talk with him in private could turn you into a mindless zombie only capable of repeatedly espousing his ideals.
- Named After Somebody Famous: He shares his surname with Asano Naganori, a 17th century feudal lord whose death by seppuku The 47 Ronin sought revenge over.
- Nightmare Face: A metaphorical one, but he faces his son with a very creepy, alien-like looking face with very gross, strangely-positioned eyes. Asano Jr.'s You Monster! reaction is indeed warranted.
- No-Holds-Barred Beatdown: To the four foreign exchange students brought in for the bo-taoshi match, who are largely built athletes, but still teenagers.
- Non-Action Big Bad: He rarely shows any extraordinary physical abilities, though with his charisma and manipulation he is a significant impediment regardless. In Chapter 94 the four foreign exchange students find out the hard way that he's a very capable and brutal fighter too.
- No Sense of Personal Space: Goes forehead-to-forehead with the coach of the baseball club (pretending to check for a fever) when threatening to fire him because Class 3-E is winning the exhibition game against them.
- Pay Evil unto Evil: After the death of Ikeda, his former student, Asano brainwashed the bullies who drove Ikeda to suicide into becoming addicted to gambling, completely ruining their lives in the process.
- Pet the Dog: In Chapter 160, it's revealed he had a soft spot for the late Aguri Yukimura. He goes on to say that she had endless amounts of vitality and a great passion for education, and she would have been an outstanding educator in a few more years, had it not been for a regrettable loss.
- Plot-Irrelevant Villain: Downplayed. He's the primary villain from Class E's point of view, especially with his attempts to undermine them in the school life side of the story. But ultimately, he's unrelated to the situation with Koro-sensei and the true Big Bad of the overall series. From a plot standpoint alone, he only took advantage of the situation in order to further his own agendas.
- The Power of Hate: Chapter 94 reveals that he believes this is a key part of learning from defeat. The feelings of hatred and humiliation stemming from a loss are what drive the losers to do better next time. The irony, however, is that that it goes both ways and when E-Class does indeed do better than his studies, he can't really seem to take the loss. Koro-sensei reminds Asano what the latter used to be and Asano realizes he too has gone too far.
- "The Reason You Suck" Speech: In Chapter 123, after revealing that all of Class 3-E reached the top 50 and won over 3-A, Asano Jr. gives him this. In retaliation, he punches his own son as he doesn't take it well.
- Rubik's Cube: International Genius Symbol: Played with. Asano's first proper appearance has him carrying a Rubik's cube, but instead of solving it, he breaks it apart, and reasons that breaking it apart by force before putting it back together is the most logical and practical way of solving it.
- Rule of Symbolism: As seen in his Establishing Character Moment, Asano's "method" of solving the Rubik's Cube shows his willingness to teach students to follow his brutal dogmatic educational system, by using any means necessary. Also, by using this tactic repeatedly, he ends up causing bad psychological damage to the same students he's trying to teach, to where it'll eventually fracture their minds, much like how the pieces of the Rubik's Cube will eventually get damaged to the point where they can't fit back altogether.
- Sadist Teacher: It is known that he teaches classes, and the students are shown to be exhausted and stressed after each class. Those who can't keep up with him are subjected to a three minute lecture which brainwashes them in academic zombies. Even though he isn't a teacher of Class 3-E, he is a bastard to them.
- Second Place Is for Losers: A philosophy he sticks to whole-heartily. He mocks his son over this in the first semester when he loses the bet to E-Class and when he loses the second-semester exams to them, he doesn't take it well in the slightest.
- Sharp-Dressed Man: Very sharp. The literal angularity of his suit makes him stand out a lot. Heaven helps you if he loosens so much as a single button.
- Signature Laugh: Fufufu. This serves as another trait of similarity between him and Koro-sensei.
- Skewed Priorities: Asano Sr. is more interested in preserving his system than keeping Koro-sensei from destroying the world.
- The Sociopath: He has not even the slightest shred of remorse or empathy for the students whose lives he actively tries to ruin. He also has the superficial charm and manipulation ability aspects of the disorder down pat. Subverted because Gakuho is capable of being kind and encouraging. However, after learning Ikeda's suicide, Gakuho blamed himself for not instilling the right values in his student and resolved to never repeat that mistake. Until Korosensei calls him out for being too ruthless. Gakuho realizes his mistake and decides to become a better person.
- Sore Loser: In the most extreme way possible. The best example is in Chapter 123. Class 3-A lost to Class 3-E during the second term finals because they couldn't concentrate on the second half of the exam as they lost the bloodlust he whipped up on them. When Asano confronts Class 3-A about this, the class, led by Asano Jr., tells him that they've come to respect Class 3-E's growth and even ask him to transfer them to Class 3-E if he's not happy. The chairman doesn't take it and slaps Asano Jr. This also results in everyone in Class 3-A leaving him.
- Surprisingly Realistic Outcome: After Koro-sensei's death, his school practices come under fire and he's eventually forced to both discontinue his system and resign as principal. Nagisa, however, figures that he was eventually expecting this.
- Tragic Keepsake: He is almost never seen without the oak leaf tie pin that his first students gave him.
- Tragic Villain: For all his ruthlessness, deep down he is haunted by his failure to instill in Ikeda strength of heart, which ultimately led to the latter's suicide and him being driven into madness as he questioned his old, compassionate approach to education. It wasn't until nine years later when he saw his old methods vindicated through Koro-sensei, allowing him to finally find his path to redemption, even if it means tarnishing his reputation with revelations of Kunugigaoka's academic system.
- Vile Villain, Saccharine Show: He's the first wholly menacing figure to appear in a series that was otherwise very light-hearted, silly and fun before he stepped in.
- Villainous Breakdown: Suffers from an outwardly stoic one after Class 3-E defeats Class 3-A in the second term exams, to the point that the students in Class 3-A ask to be put into 3-E to learn from their teaching methods rather than his own. First, he slaps his son hard across the face in full view of the rest of the class, then he attempts to destroy the former's campus, kill Koro-sensei and place Class 3-E in what is essentially a prison. Gakushu realizes it and points it out.Gakushu Asano: Your face looks like it's glitching out. Uh oh, don't tell me I'm finally seeing your fatherly side.
- Villain with Good Publicity: He's respected and liked by students and teachers from the main campus and has won several awards for his top-notch educational system. At the same time, he treats Class 3-E in a way that violates Japanese school regulations. He not only approves of Takaoka's violent punishment methods until they became ineffective, but he also beats the hell out of the four exchange students, which is definitely illegal and criminal. Then it all comes crashing down at the epilogue after revelations of his more unsavory methods created a huge public backlash that forced him to resign.
- Well-Intentioned Extremist: His system intends to ensures that the top 95% of the student body becomes highly successful... by treating the lower 5% like garbage. His true motive is to instill "true strength" into the minds and hearts of his students, so that they will have the fortitude to progress through life without giving up and committing suicide, like Ikeda did.
- Worthy Opponent: He comes to view Koro-Sensei as this, developing a level of respect for his teaching methods and complimenting a recently deceased Koro-sensei to Nagisa.
- You Have Outlived Your Usefulness: He fired Takaoka. His objection wasn't even with Takaoka's use of violence as a teaching method. While he disapproved of it, the real reason he stepped in was that Nagisa beat Takaoka in their fight, which meant the class would never be afraid of Takaoka again.
Class 3-A
The tip-top of the student body of Kunugigaoka Junior High. Led by the Chairman's son Gakushuu Asano. General
- The Aces: The "Five Virtuosos" are the top in their respective subjects. And come with the requisite ego to match.
- Character Development: When they're completely trounced by Class 3-E for the second-semester exams, they all realize that Asano Sr.'s methods were ineffective and humbly accept their defeat, even volunteering to be transferred out to Class 3-E.
- Everyone Has Standards: Arrogant Jerkasses of epic proportions they might be most of the time, but the "Five Virtuosos" are horrified at Principal Asano's suggestion that they should have poisoned the food Class 3-E was selling during the School Festival.
- Out of Focus: Their role in the story becomes virtually non-existent after Class E defeated them on the second-semester exams.
- Rich Bastards: Four of the Five Virtuosos don't care about the holidays trip because their families travel to better places and the Asanos has a maid and a chauffeur. All of them are huge assholes.
- Slobs Versus Snobs: The snobs to Class 3-A's slobs.
Gakushuu Asano
Gakushuu Asano (浅野 学秀 Asano Gakushū)
Voiced by: Mamoru Miyano (Japanese, TV anime), Micah Solusod (English) Foreign VAs
Student Council President of Kunugigaoka Junior High School, the best-performing member of the Five Virtuosos, and son of Gakuhou. He is every bit as domineering as his father but lacks his sense of greater purpose. Before the first term finals, he leads Class 3-A, comprised of the school's top students, in a massive group study session to ensure Class 3-E cannot upset the school's established system at his father's behest.
- The Ace: Essentially the best student in the school, who consistently ranks first in every subject in all the exams he takes, and also speaks multiple languages and displays astonishing martial arts ability. Only during the first term finals does he start to lose some of his first places to a few Class E members (Okuda, Isogai, and Nakamura), though he remains an excellent student even then; he notably ranked either first or second in all his subjects during the Final Exam arc.
- Antagonistic Offspring: His relationship with his father is basically this. He wants to keep his father like a pet, while his father intends to make him a corporate slave for the rest of his life. Although it's shown in Chapter 94 that Asano Sr. is worse.
- Arc Villain: Chapters 50-54, and again in 90-94.
- Aw, Look! They Really Do Love Each Other: After Asano Sr. is brought back from the edge after Korosensei beats his workbook/grenade challenge, he and Asano Jr. bond by talking about how much money they're going to make by suing each other.
- Badass Bookworm: Asano Jr. is unrivaled when it comes to academics. It's revealed that he has the martial art skills to force the boys of Class 3-E into a pinch.
- Break the Haughty: Hit with this in Chapter 54, with his father rubbing salt into the wound.
- Cunning Linguist: In Chapter 90, he's seen speaking English, French, Korean, and Portuguese with astonishing ease.
- Empty Eyes: He lacks any glimmer in his eyes, presumably to make him look more focused and ruthless, and also to make him look similar to Karma.
- Even Evil Has Standards:
- On the wrong side of this trope, even his fellow Virtuosos, none of them pleasant people, think of him as black-hearted.
- On the right side, he becomes increasingly disgusted with his father, and him basically turning his classmates into vengeful zombies just to defeat Class 3-E was the last straw for him, driving him to actually beg Class 3-E to stop his father.
- Insane Troll Logic: Like father like son. Of course, the easiest way to beat your dad in your little info war is... an extended examination beat-down contest with Class 3-E to force them to tell you what he's hiding? The thought to ask never crosses his mind.
- Last-Name Basis: With his own father, though this isn't too uncommon in a formal setting. Also, everyone else calls him by his last name, too. To distinguish him from his father, the chairman is always referred with his title before his name.
- A Lighter Shade of Black: In comparison to his father. Both of the Asano's are rather unpleasant, but whereas Gakushuu is merely extremely prideful and content with proving his superiority, Gakuhou is extremely dogmatic in the belief that his teaching philosophy is correct, and will stop at nothing to prove it. Fittingly, while Gakushuu knows where to draw the line and drops his antagonism towards 3-E first, Gakuhou will stoop to any low, is Defiant to the End, and doesn't remotely drop his antagonism till the final act of the series.
- Magnetic Hero: Or at least. Somehow he has a lot of friends from around the world who show real loyalty to him on multiple occasions.
- Meaningful Name: His name means "excels at study." His father knew exactly what he was going for when he named him.
- Motive Decay: When he first appears, he opposes Class E because he wants to figure out their secret (Koro-sensei) in hopes that it will give him some leverage he can use against his father. After Class A loses their bet on the First Semester Finals, however, he becomes focused on defeating Class E for the sake of avenging his wounded pride.
- Only Sane Man: He was the most insightful when noticing all the strange happenings around Class 3-E. He was also the only person unaffected by his father's brainwashing for the finals, given that his father dismissed him earlier in his classroom.
- Overlord Jr.: He is the son of Chairman Asano, and is just as ruthless as his father.
- Pragmatic Villainy: He eventually realizes that while his father's system produces results, it's ultimately too inefficient, in addition to horrifying. Sure enough, he's proven right during the second-semester finals. While their brainwashing-induced bloodlust helped them through the first half, by the second half that bloodlust had worn out and they started tripping up enough for Class 3-E to monopolize the top spots.
- "The Reason You Suck" Speech:
- Receives one from his father in Chapter 54 after losing the bet with Class 3-E. His father mocks his plan to turn him into a pet when he couldn't even win against people his own age.
- Happens again by the same person 40 chapters later.
- The Rival: To Karma in the First and Second Semesters' Final Exam arcs, and to Isogai in the Sports Festival arc. In the ending, Asano Jr. also vows before Karma, the only Class 3-E student who will surely enter Kunugigaoka's high-school department, to make him spill the beans over the truth of their past year.
- The Sociopath: He's inherited most of the traits his father displays, in particular the charisma and callous manipulative behavior.
- Strong Family Resemblance: Asano is a dead ringer for a younger Chairman Asano.
- Took a Level in Kindness: While still rather arrogant and rude, after he is humbled by Class 3-E, he denounces his father's methods and stops antagonizing the class. After Korosensei's existence is made public knowledge and the class are being hounded by reporters, he has the other Big Five help him in shielding the class from them while escorting them to the bus, saying he can't be a proper ruler if he can't protect his subjects.
- Worthy Opponent: While he holds most of 3E in absolute disdain for most of the series, the two members he outright admits to be worth his effort to beat are Isogai and Karma. Which makes sense, considering that both Karma and Isogai are the only members of 3E whose placement in said classroom has nothing to do with thier schoolwork and are aces in thier own right. Asano will only accept the bests as his rivals
- You Monster!: His reaction to his father's metaphorical Nightmare Face.
Teppei Araki
Teppei Araki (荒木 鉄平 Araki Teppei)
Voiced by: Anri Katsu (Japanese, TV anime), Jessie James Grelle (English) Foreign VAs
One of the Five Virtuosos, ranked second in the school, specializing in social studies. As head of the Broadcasting Club, he had a few cameos before being formally introduced. He was one of the speakers in the May school assembly, and the announcer in the exhibition baseball match.
- Mouth of Sauron: Though it's not any kind of official capacity, most of the time when he appears he's the one implementing Asano Sr.'s vision of the school by inciting the other students to mock Class 3-E, since the chairman himself doesn't often involve himself in the day-to-day lives of his students.
- The Rival: To Isogai in the first-semester finals arc, regarding social studies.
- Smarmy Host: Makes constant obviously disparaging comments about Class 3-E in his speeches.
- Younger Than They Look: In his first appearance (Chapter 11), if you didn't notice he was wearing a student uniform you might think he was a member of the faculty.
Ren Sakakibara
Ren Sakakibara (榊原 蓮 Sakakibara Ren)
Voiced by: Kaito Ishikawa (Japanese, TV anime), Justin Pate (English) Foreign VAs
One of the Five Virtuosos, ranked third in the school, specializing in Japanese.
- Casanova Wannabe: He enjoys flirting with girls, and he flirts with Kanzaki, too.
- Handsome Lech: Despite his good looks and charms, his sense of personal space around the girls he flirts with is quite dreadful.
- The Rival: To Kanzaki in the First Semester's Final Exam arc regarding Japanese.
- Token Good Teammate: Though, he is still pretty arrogant, he just doesn't badmouth Class 3-E that much than the others.
- Worthy Opponent: He comes around to viewing Kanzaki as one fairly quickly.
Natsuhiko Koyama
Natsuhiko Koyama (小山 夏彦 Koyama Natsuhiko)
Voiced by: Teppei Akahira (Japanese, TV anime), Aaron Roberts (English) Foreign VAs
One of the Five Virtuosos, ranked fifth in the school (Karma is fourth), specializing in science. Prior to the first term finals, he appeared only in Terasaka's pre-Class 3-E flashbacks.
- The Friend Nobody Likes: Even the other Virtuosos don't seem to care for his presence very much.
- Gonk: With his extremely crooked teeth, bizarre eyes, and grotesque expressions, he really sets the bar for ugliness high.
- Hypocritical Humor: He insults Okuda for looking like a hick for her glasses, and asks Teppei for confirmation. Nevermind that he and Teppei wear glasses themselves.
- Nightmare Face: How he's introduced. It's soon revealed to be his default expression.
- The Rival: To Okuda in the first-semester finals arc, regarding science.
- Unknown Rival: To Karma in the first-semester finals arc regarding the rank of fourth-best student.
- Victory Is Boring: Feels no satisfaction from beating Karma in the finals because the latter screwed himself over by not studying.
Tomoya Seo
Tomoya Seo (瀬尾 智也 Seo Tomoya)
Voiced by: Shun Takagi (Japanese, TV anime), David Trosko (English) Foreign VAs
One of the Five Virtuosos, ranked sixth in the school, specializing in English. Was also Kaho Tsuchiya's boyfriend for a brief time before a prank orchestrated by Class 3-E caused them to break up.
- Adaptational Late Appearance: In the manga, he first appeared in Chapter 23 as Kaho Tsuchiya's on-and-off boyfriend, before getting a proper introduction in Chapter 50 along with the other Four of the Five Virtuosos. Since Kaho is Adapted Out in the anime, he makes his first appearance alongside the other Virtuosos.
- Foreign Exchange Student: Not currently, but spent a year abroad in Los Angeles because of his parents' work.
- Jerkass: Beyond the normal non-Class 3-E unkindness, he is verbally abusive even to his own classmates while he tutors them. And to old people, too.
- Laxative Prank: A victim of this. After humiliating Maehara in front of his ex-girlfriend, Class 3-E teaches him not to look down on the weak by spiking his drink with a bowel irritant.
- Pride: Has a strange, almost obsessive vanity. When sitting under an awning in the rain he remarks, apropos of nothing, about what a sense of superiority it gives him to be in the only dry area.
- The Rival: To Nakamura in the first-semester finals arc, regarding English.
The Foreign Exchange Students
Four largely built athletes invited to Kunugigaoka by Asano Jr. during the annual athletic festival. Asano Jr. uses their strength to give his team an overwhelming advantage against Class E in the bo-taoshi match.
- The Big Guys: The four foreign exchange students are ridiculously huge and are top sportsmen.
- The Brutes: Literally intended to crush Class E in the bo-taoshi match.
- The Ace: The four foreign exchange students are top class sportsmen in their respective fields.
- Kevin: The American National Junior Football representative.
- Camille: The next generation's ace at a famous wrestling gym in France.
- Sang-Hyuk: A rising star in the Korean basketball world.
- José: The son of an international fighter from Brazil, apparently in MMA.
- The Cameo: José shows up in Chapter 102. He is one of the Brazillian soccer fans who are pissed of by Koro-sensei mentioning 7 to 1.
- Dumb Muscle: The four exchange students are invited to the school by Asano Jr. for the sports festival, so Class 3-A has an athletic and physical advantage against Class 3-E. The four leave the thinking to Asano.
- Foreign Exchange Student: Asano Jr. calls up four foreign top sportsmen to transfer to his school so that his class can defeat Class 3-E in the sports festival.
- Graceful Loser: When Chairman Asano rebukes his son over his failed leadership causing his team to lose, Kevin steps in to defend him, saying that defeat can be a lesson and that Gakushu did the best he could.
- Only One Name: The four exchange students.
- True Companions: To Asano. Kevin stands up for him when Chairman Asano gives his son another "The Reason You Suck" Speech. With bloody consequences.
- Younger Than They Look: The four foreign exchange students are 15 years old like the rest of the class, but they look much older. No wonder some characters doubt their age.

Kazutaka Shindou (進藤 一考 Shindō Kazutaka)
Voiced by: Takuya Sato (Japanese, TV anime), Christopher Wehkamp (English) Foreign VAs
The captain of the school's baseball club, who is able to pitch fastballs on the level of pro players.
- The Ace: How he sees himself and his team members, who all excel in both military (sports) and literary (study) arts. He refers to them as the chosen ones.
- Boisterous Bruiser: He's prone to making boasts.
- Blunt "Yes": To when Karma questions whether he really is a chosen one.
- Brainwashed and Crazy: He and the whole baseball team are "motivated" by Asano Sr. during the exhibition match against Class 3-E. He only uses his choice of words and charisma to manipulate their minds so that they are entirely focused on winning. This causes them to act like berserkers.
- Crippling Overspecialization: His pitches are incredibly fast for a middle-schooler, but since he only has two different pitches, Class 3-E was able to counter and manipulate him easily until Asano Sr. mixed things up.
- Friendly Enemy: The baseball club was always less malicious towards Class 3-E than the rest of the school. They mostly limited themselves to a few insensitive comments and being typical arrogant jocks.
- Friendly Rivalry: With Sugino, with a power-vs.-technique dynamic. He acknowledges it after Class E wins the exhibition match.
- Heel–Face Turn: He is the first main campus student to openly help Class 3-E, even if only in a small way.
- I Always Wanted to Say That: He always wanted to introduce a group of people like an over-the-top announcer. He gets his chance with the Five Virtuosos.
- Large Ham: He really enjoys being overly dramatic.
- Mind-Control Eyes: When "brainwashed" by Chairman Asano.
- Token Good Teammate: Despite his initial Smug Super attitude before his Heel–Face Turn, he had always been leagues better than the rest of the main campus students towards 3-E. At worst he's was a arrogant Jerk with a Heart of Gold and even that firmly got better after his Heel–Face Turn.
- Unskilled, but Strong: He uses a fastball 90% of the time, a fastball that flies at 140 kilometers per hour. Naturally, 3-E exploits this initially by only using bunts.
- Worthy Opponent: Shindou considers Sugino as one, to the point of warning him of Class A's antics.
Nobuta Tanaka and Chousuke Takada

Chousuke Takada (高田 長助 Takada Chōsuke)
Tanaka voiced by: Hiroki Gotou (Japanese, TV anime), Chris Guerrero (English) Foreign VAs
Takada voiced by: Masahito Yabe (Japanese, TV anime), Dallas Reid (English) Foreign VAs
L-R: Tanaka, Takada
Nagisa's two former classmates, currently in Class 3-D. They are pathetic Gonks who believe (like everyone else) they are superior to the students in Class 3-E, but they are close to falling into this very class themselves.
- All There in the Manual: Their names.
- Blatant Lies: When they harass Nagisa because they didn't like how happy he seemed, they corner him. When he doesn't seem threatened or bothered by them, they threaten his life. All it takes is a non-threatening Wham Line and a Death Glare on Nagisa's part to scare them off. Then they go and tell everyone that they were the ones given a death threat.
- Butt-Monkey: They never get luck in their life. For example, they are the first characters shown in the series to get a foretaste of Nagisa's bloodlust.Their appearances are also book-ended by trying to bully Nagisa, only to be counter-bullied by Karma.
- Gonk: Like most other non-Class 3-E students, they are ugly.
- Hate Sink: They are a couple of Jerkasses with no impressive or admirable qualities between the two of them. Even the Five Virtuosos are at least given some humanizing traits.
- Heterosexual Life-Partners: The hetero part is a bit doubtful; for some reason, they are apparently closer than normal friends.
- Jerkass: During both the baseball game and the buotaoshi game, they were only watching in hopes of seeing Class 3-E get crushed. During the latter they even joked it was "lynch time" when it looked like E was surrounded and going to get pummeled.
- No Name Given: The story never reveals their names.
- One-Steve Limit:
- Class 3-A has a student with the name Tanaka.
- Their last names themselves sound very similar.
- Straw Loser:
- They are proud that are not in Class 3-E, yet their grades are so low they could fall into the very class they hate. Ironically, Class 3-E is already able to compete with Class 3-A.
- They watch the baseball match between the Class 3-E boys and the baseball team to feel better after their own loss against another class. After Class 3-E wins, they are pissed off and claim that the match was boring.
- Those Two Guys: They appear always together and have no distinct characterization that tell them apart.
Kaho Tsuchiya
Kaho Tsuchiya (土屋 果穂 Tsuchiya Kaho)
A girl from the main school. Has or tries to have at least three different boyfriends over the course of her short appearances, mainly just for the sake of having one.
- Adapted Out: Her appearance was omitted from the anime.
- Bad Liar: Lies often, about anything and everything that may cause her embarrassment. It's always obvious when she does, but Seo at least is perfectly happy to let it slide.
- Bitch in Sheep's Clothing: Though she tries to pass herself off as merely playful, her spite for everyone who isn't useful to her is clear.
- Laxative Prank: A victim of this. After humiliating Maehara in front of her new boyfriend, Class 3-E teaches her not to look down on the weak by spiking her drink with a bowel irritant.
Kokona Tagawa
Kokona Tagawa (田川 ここな Tagawa Kokona)
A false friend of Megu Kataoka.
- Adapted Out: Her appearance was omitted from the anime.
- All Just a Dream: In a dream, she visits a beautiful moonlit oasis where a bunch of mythical, fish-like creatures teach her how to swim. What she never finds out is that it really happened: the oasis was actually Class 3-E's private mountainside pool, while the creatures were really just Koro-sensei, Kataoka, Nagisa and Kayano disguised in ridiculous yet adequately convincing costumes.
- Book Dumb: She forces Kataoka to help her with her studies.
- Blackmail: She blames Kataoka for nearly drowning in the ocean because she "didn't teach her how to swim properly" despite it's her own fault. She uses this event to guilt trip Kataoka into help her study.
- Fan Disservice: Licking on Kataoka's arm. And Kokona's face isn't pretty at all.
- Girlish Pigtails: Has her hair tied up in these with small beads.
- Manipulative Bitch: Manipulates Kataoka into being her personal tutor by convincing her that she almost killed her.
- Super Drowning Skills: Until Kataoka teaches her how to swim properly.
- Taking Advantage of Generosity: To Kataoka.
- Too Dumb to Live: Even though Kataoka told her that she needed more swimming practice, Kokona still swam in the ocean and nearly drowned.
Kunudon
Kunudon (くぬどん Kunudon)
Voiced by: Kurumi Mamiya (Japanese), Lindsay Seidel (English) Foreign VAs
Kunugigaoka Academy's mascot, a cartoon sawtooth oak acorn (after which the school is named).
- Ascended Extra: In the manga, Kunudon only appears in the extra pages in the volumes. In the anime he appears to explain the information from those extras.
- Bitch in Sheep's Clothing: To the public, he's a saccharine cartoon character concerned with everyone being happy and having fun. But when he's talking about Class 3-E, he's basically a drill instructor who treats them like trash.
- Blatant Lies: According to Kunudon, Kunugigaoka is a place where everyone is treated as equals, and every day is fun.
- Precision F-Strike: In the English dub of Season 1 Episode 17, after realizing that Class 3-E is rewarded with the Okinawa trip after acing the first term finals:"Wait! E Class is going this year?! F**k that!"
- You Have Outlived Your Usefulness: He is fired by Asano Sr. at the end of Season 2 Episode 12, and the next episode shows him living the life of a bum.
