The viewpoint character of the series. He is a high school student who was born with all manner of psychic abilities despite having very ordinary biological parents. Because of the misery that comes from the attention he receives as a psychic, Kusuo desires a normal, plain life, keeping average grades and performance in sports activities.

Saiki Kusuo

    Saiki Kusuo - Character Profile

"What a pain."

Voiced by:Shintarō Asanuma (vomic and flash anime), Hiroshi Kamiya (TV anime) and Haruka Tomatsu (Kusuko) (Japanese), Jerry Jewell and Jamie Marchi (Kusuko) (English Funimation), Kyle McCarley (English Netflix), Alejandro Orozco (Latin American Spanish)

Portrayed by:Kento Yamazaki

"Good grief...ordinary people sure are a pain."

A 16-year old boy with extremely powerful psychic powers. He could use them to effortlessly have anything he wanted, but instead opts to settle down for a peaceful and quiet life.

  • Afraid of Their Own Strength: If Saiki isn't careful, people will get hurt. Badly. He hates PE because he knows he could easily kill a person by simply throwing a ball at them. He also tries to keep his powers in check out of fear that he might cause the apocalypse by accident.
  • Ambiguous Gender Identity: Saiki's gender identity comes into question when he reveals he was actually born as a girl because his shapeshifting powers manifested while he was still in his mother's womb. He's sure he was conceived as male, hence he keeps that gender as his Shapeshifter Default Form. Normally, Saiki is comfortable with living as a man and only takes female form when he needs it for a specific goal, but he doesn't seem to view his own gender as being particularly important to his identity. On one occassion, his first plan for avoiding attention in a world where he's become incredibly popular was to become female for life, and he doesn't seem to have any problems with it until he finds out that his female form is also quite popular.
  • Asexuality: And aromantic. Saiki claims that he has no interest in or understanding of romance or sexual attraction, since he can read everyone's minds and can't see outer beauty because of his X-Ray Vision. And a big part of the series is him avoiding people who are in love with him. Extra points because he always tries to help his friends except when they're trying to do something romantic with him. That being said, he admits to himself that Teruhashi is beautiful in Reawakened when he finally can see her normally thanks to the suppression of his powers. He still wasn't attracted to her, though.
  • Attractive Bent-Gender: His female form, Kusuko/Kuriko, attracts the unwanted attentions of Takahashi and his friends.
  • Aw, Look! They Really Do Love Each Other: He gets moments like this with most of the main characters — despite consistently deriding their actions in his inner monologue, Saiki does care about them and looks out for them with his psychic powers.
  • Be Careful What You Wish For: After constantly wishing that he could have a normal life without his psychic powers, he finally got what he wanted in the last chapters. However, he seems to be none too happy about it, as it left him with disadvantages such as unable to notice people wanting to talk to him from behind along with the surprise attacks that have planned against him. It is through this experience that he is finally able to accept having an exciting life with his psychic powers.
  • Berserk Button: He might be a stoic dude, but even he has a few:
    • Don't mess with his desserts.
    • Don't cheat. Though this mainly entails not cheating to advance yourself at the expense of others, as he admits to cheating on exams in order to enforce his facade of being a normal person (copying other students' work, complete with all mistakes, when he's more than smart enough to ace the exams).
  • Blessed with Suck: His powers take away many kinds of enjoyment and he hasn't complete control over them.
  • Bumbling Sidekick: Kaidou sees Saiki as his hapless sidekick in the fight against the Dark Reunion. To emphasize this, Saiki is drawn with softer features and given a higher voice in Kaidou's daydreams. Saiki is actually the furthest thing from this trope.
  • Bystander Syndrome: He initially didn't help Akechi when he was being bullied as he didn't want his psychic powers to be known.
  • Can't Live With Them, Can't Live Without Them: Has his dynamic with his psychic powers where, despite constantly complaining about them, he has grown far more used to them than he would like to admit.
    • A notable example is his telepathy. Saiki states that he dislikes this power the most, but once he obtains a ring that cancels it out, he becomes very paranoid while using it simply because he's so used to reading everyone's thoughts. This also leads to more harrowing situations, as he can't predict people's actions anymore.
  • Cannot Talk to Women: Teruhashi rationalizes Saiki's extreme apathy as him being too awkward to say anything around her. In her internal monologue, Saiki is given softer features and more awkward mannerisms.
  • Catchphrase: "Yareyare"/"Good grief", which he says so much that his father and Toritsuka overuse it when pretending to be him.
  • Celibate Hero: Romance tends to annoy him, especially when Teruhashi is involved. Unfortunately for him, nothing he will do can foil Teruhashi's crush on him.
  • Character Development: Slowly starts to appreciate the people around him as the series goes on. In the last chapter he accepts his psychic powers and exciting life because of them.
  • Chick Magnet: Despite the claims that he’s “average”, four girls end up attracted to him at some point, much to his chagrin.
  • Comically Invincible Hero: His numerous powers can bail him out of virtually any undesirable situation. This doesn't stop undesirable situations from happening to him anyways.
  • Cover-Blowing Superpower: Revealing his powers to the world will attract unwanted attention to himself.
  • Deadpan Snarker: Of the First-Person Smartass kind. He is also capable of picking up on other people's snark with his own telepathy.
  • Debt Detester: The one thing he hates more than standing out is owing someone a favor.
  • Deliberate Under-Performance: He knows that he could ace every test with his nigh-infinite Psychic Powers, but doesn't want to draw attention to himself and just wants to live a quiet life — so he uses his powers to get grades that are just high enough to keep him in the middle of the rankings.
  • Family Theme Naming: Everyone in his family, including him, has a given name that starts with 'Ku'.
  • Fourth-Wall Observer: Saiki's inner monologue is specifically addressed to the reader, but he doesn't Break the Fourth Wall aloud.
  • Freudian Excuse: He doesn't like Takahashi very much since he resembles a bully who used to torment Akechi when they were in elementary school, which eventually caused Kusuo to snap, unleash his psychic powers, and transfer schools after mind wiping them.
  • Friendless Background: His aim. His classmates don't collaborate.
  • Grumpy Bear: He's very cynical despite living in a very pleasant world.
  • He Who Must Not Be Heard: In the beginning, it was left ambiguous whether he can't speak, won't speak or doesn't speak on screen until a few scenes began to clarify that it leaned towards won't speak or at least not on screen.
    • A a few Imagine Spots have characters imagining him speaking, so it's likely they've heard him before off screen. Furthermore, it's established early on that he can communicate telepathically as his father was able to give Saiki a direct answer when he asked why his parents couldn't move their furniture on their own. The speaking off screen theory also gains some support when Saiki appears to have said that he wasn't going to the beach with Nendou out loud, as his mother instantly scolded him into going. As his head was turned in that example, it's very likely he was moving his lips and we just didn't see.
    • His interactions with Toritsuka in the latter's introduction clearly have him using telepathy to communicate without moving his lips, although one shot in the anime seems to have him physically talking as his mouth changes position, but it's too zoomed out to tell if he was moving his lips.
    • The first unambiguous case of him speaking physically on screen in the anime occurs in episode 5, where he says "Oh, wow" after realizing that he didn't need to get a buzzcut since while his class lost sports day, they beat the specific class they made the bet with.
    • Later on, he can be seen shouting “Dammit!” when Nendo catches him without his glasses and gets petrified as a result.
  • Hypocritical Heartwarming: Towards his parents. While he might find them embarrassing, especially his dad, but he does not react well to anyone mocking them.
  • I Just Want to Be Normal: He doesn't really want to become a normal person but he wants to live quietly as one.
  • I'll Kill You!: Threatens to kill Toritsuka with a sharpened roll of toilet paper if he ever reveals that he's a psychic to his classmates.
  • Jerk with a Heart of Gold: He's normally cold and says some really mean things about his classmates in his head, especially about Nendou, but when it comes down to it, he'll help any of them, including Nendou.
  • The Knights Who Say "Squee!": The only consistent time he gets emotional for real is when he's gushing over Satou's average mundane life.
  • Light Girl, Dark Boy: Saiki's hair becomes a much lighter shade of pink when he transforms into a girl.
  • Logical Weakness: He can read minds, but it takes time for him to listen and understand what the mind is saying. That means he cannot detect someone who barely thinks, and that's how Nendou often get the drop on him, despite Saiki's attempt to avoid him.
  • Loners Are Freaks: Subverted, as everyone in his school tries their hardest to get his attention despite his loner tendencies. It helps that his psychic powers give him a far better ability to read social cues and have the skills normal examples of the loner archetype lack.
  • Loony Friends Improve Your Personality: He's constantly annoyed by the classmates who consider him a "friend", but they make his life a lot more interesting and his interactions with them do humanize him.
  • Magnetic Hero: Ironically, he would rather not be one, but his classmates insist on befriending him anyway. It's lampshaded on multiple occasions (such as when Kuboyasu transfers in) that Saiki is the character that ties the main cast together.
  • Medium Awareness: The way his thoughts are framed makes it clear that he's speaking to us, and that his psychic powers let him know he's a fictional character. Best demonstrated when he makes him self visible to the viewers of the show so that the audience can see him while remaining invisible to the other characters in the story. When other characters gain the ability to break the fourth wall later on, only Saiki still knows how the show really works.
  • Mistaken for Romance: Teruhashi's fan club comes to the conclusion that Saiki is her boyfriend and Yuuta is their lovechild. They're right that Teruhashi has feelings for him, though.
  • Morton's Fork: With his telepathy, he's forced to listen to everyone's thoughts in a rather large radius. Without his telepathy (by negating it via the germanium ring), he becomes The Paranoiac and is more nervous around people because he can no longer read their thoughts and predict their actions.
  • New Powers as the Plot Demands: Played for Laughs and Deconstruction purposes instead Deus ex Machina. Saiki always has a power useful for solving the crisis at hand, but because of his powers' limits, shenanigans usually ensue.
  • No Guy Wants to Be Chased: Saiki goes out of his way to try to avoid Teruhashi and Yumehara's advances.
  • Not Bad: Saiki will never admit he actually likes something (not even coffee jelly). Instead, he'll just claim that he "doesn't dislike" it.
  • Not Distracted by the Sexy: Saiki is notable for being completely immune to Teruhashi's beauty and charm (it comes with the mind-reading). He's also unaffected by Aiura's buxom figure, even though many other guys point it out.
  • Not So Above It All: For all of his criticism of other characters' wackiness, Saiki can be just as silly as any of them, especially when sweets are involved. He also has a thing for truly heartwarming moments.
  • Not So Stoic:
    • Accidentally using psychometry on a person who can see ghosts causes him to look terrified.
    • He visibly freaks out when confronted with bugs.
    • Becomes more expressive and turns into a fanboy whenever around the utterly average Satou.
  • Obsessively Normal: Saiki makes an effort to be totally average in grades, sports, and appearance so he doesn't stand out. Of course, he's anything but normal, and winds up nearly always surrounded by an increasing number of larger-than-life personalities. Lampshaded by Rifuta, who can't understand why Teruhashi would like a guy as mediocre as Saiki pretends to be.
  • The Omnipotent: Of the Type 5. Possibly Type 3. Saiki basically has every psychic power in the book, and can utilize them in creative ways, leading to this trope.
  • Only Sane Man: To virtually every other character in the series — Saiki loves to call out their flaws and quirks. Despite this, he's also Not So Above It All.
  • The Paranoiac: Only when he has sealed his telepathy with his germanium ring. He's very paranoid of everyone around him having gotten used to hearing their thoughts.
  • Power Incontinence: He has problems controlling his own strength (see each specific power for description). It temporarily becomes an even greater problem after Nendou briefly unplugs one of his antennae. It gets so bad that it could create an apocalypse.
  • Power Limiter:
    • The antennae on his head keep his powers in check.
    • He can wear a germanium-alloy ring to shut-off his Telepathy, as shown when he went to a movie theater.
    • His glasses also restrain his petrifying gaze.
  • Pretending to Be One's Own Relative: Saiki runs into his female classmates while in female form and they find his notebooks in "Kuriko's" bag. They end up assuming "Kuriko" is Saiki's younger sister. Saiki rolls with it so they don't find out about his powers.
  • Pride Before a Fall: While Saiki doesn't really have an inflated ego, he's still absurdly confident in his intelligence and powers. He very often underestimates the stupidity and determination of everyone around him, which can sometimes result in unexpected problems.
  • Psychic Powers: Saiki has just about every basic psychic power in the book, plus a variety of others powers that are described as psychic in origin. A list with his known powers is in a separate folder below.
  • Punny Name: "Saiki Kusuo" sounds like "saikikku", the Rōmaji form of "psychic".
  • Randomly Gifted: He's the son of a perfectly normal couple and just happened to be born with godlike Superpower Lottery.
  • Reflectionless Useless Eyes: Saiki's eyes don't normally have reflections, possibly to indicate his psychic powers and serious no-nonsense nature. This acts often as a visual clue to the viewer about who is the real Saiki, for example when a) he transforms into someone/something else (where he retains his reflectionless eyes), b) someone else is transformed to look like him (but have eyes with reflections), or c) someone is having an Imagine Spot featuring him (usually Imagination!Saiki has reflections in his eyes to make him look more lively/softer).
  • Second Year Protagonist: Saiki and most of the other student characters are in their second year of high school. This allows the story to have both younger freshman and older senior characters without having to deal with things like college exams. And thanks to Comic-Book Time, they remain sophomores for quite a few in-universe "years" — Saiki deciding to put a stop to the loops and move on to senior year happens near the end.
  • Secret Secret-Keeper: Because of his telepathy, he already knows all secrets everyone around him has yet still pretends to not know. Particularly about Teruhashi's true personality, Kuboyasu being a Former Teen Rebel and his grandfather being a big Tsundere.
  • Serious Business: Anything that he "doesn't dislike", but particularly sweets.
  • Shading/Colour Dissonance: Saiki's deep pink hair is shaded black in the manga panels, akin to characters with black or very dark hair.
  • Shapeshifter Default Form: Saiki has the appearance of a guy with pink hair as his default form. He has the ability to transform into anything he wants, which manifested before he was even born. Throughout his mother's pregnancy, the CT scans showed Saiki taking crazy different shapes, but his parents and the doctors brushed it off as the machine malfunctioning.
  • Shipper with an Agenda:
  • Signature Headgear: He always wears a pair of antennae/"hair pins" on both sides of his head. These are actually special devices that serve as a Power Limiter for his psychic powers.
  • The Silent Bob: Played With. Saiki almost never talks with his mouth, since he prefers using telepathy to communicate with others. His older brother Kusuke invented a headgear that blocks off Saiki's telepathy, but he can still hold conversations with his brother because Kusuke can accurately guess what Saiki wants to say to him.
  • Silent Partner: He has never been seen talking to another living being till the final chapters.
  • Sobriquet Sex Switch: He calls his female form Kusuko or Kuriko, which is only slightly different from his given name Kusuo.
  • The Social Expert: An unconventional example, because despite preferring being left alone, his powers let him easily figure out what makes other people tick.
  • Stalker Without a Crush: He makes something of a habit out of following Hiroshi Satou around in the school so he can gush over how ridiculously normal Satou's daily life is. It gets kinda creepy when Saiki goes to the extreme of using his clairvoyance to spy on Satou while the latter is using the toilet.
  • The Stoic: He constantly wears a bored, deadpan expression and rarely cracks a smile. Enhanced by his Stoic Spectacles.
  • Sugar-and-Ice Personality: He's stone-faced, cool-headed and very sarcastic. Beneath that, he's a good and helpful guy who cares about his family and friends.
  • Supering in Your Sleep: If Saiki's head device is taken off or malfunctions, he can have "accidents" where his powers activate in his sleep and he only realizes it after he wakes up. Such as making an entire hotel disappear or traveling to the past.
  • Superpower Lottery: A big winner. Saiki has nearly every psychic power in the book, but considers them a hassle and would prefer to live a quiet life.
  • Suspiciously Specific Denial:
    • During the shipwreck chapter, he was suddenly beset by a mysterious illness that knocked him unconscious. It was most definitely not seasickness.
    • He dislikes bugs because he is unable to read their thoughts. He's certainly not afraid of them because they are gross.
  • Sweet Tooth: He's completely obsessed about sweets, especially coffee jelly.
  • Trademark Favorite Food: He will do anything for coffee jello.
  • Tsundere: Saiki constantly claims that he cares very little for the people around him, but in reality, it doesn't actually take as much prodding as you'd otherwise think for him to help them. He outright admits that he inherited this from his grandfather.
  • Unhappy Medium: He has access to seemingly every psychic power in the book, but is unable to shut them off, which has resulted in them robbing his life of any surprise, challenge, or sense of accomplishment. This includes being able to hear the thoughts of everyone around him, but he has enough mental fortitude that it's simply an annoyance to him.
  • Unreliable Expositor: Sometimes, Saiki is not completely sincere in his inner monologues, both to the reader and himself. Some examples are more obvious, like his incapacity to admit he likes something or his attempts to rationalize his fear of bugs. Other are more subtle and open for interpretation.
  • Why Did It Have to Be Snakes?: Kusuo can't tolerate bugs because he can't read their thoughts. It isn't because they look disgusting and he doesn't want to touch them even with psychokinesis.
  • Willfully Weak: If Saiki wished it, he could end the world in three days. However, he restrains himself a lot and almost never willingly uses his powers to their full potential.
  • With Great Power Comes Great Responsibility: He is aware of his potential to rule or destroy the world, but he just wants a quiet life, and he never uses his powers to anything dishonest, only to help the people he believes to deserve help or punish those he thinks deserve it.

    Saiki Kusuo - Psychic Powers 

Saiki has a big variety of powers, but every one of them is described as psychicin origin. As the series advances he keeps to reveal or discover even more of them, so the trend is that this list will just continue to grow.
  • Astral Projection: He can separate his soul from his body willingly.
  • An Ice Person: He can create ice with his powers.
  • Brought Down to Normal: The final arc has him lose all of his psychic powers, and he's able to live like a regular human being...for a while, at least. The final chapter shows that they came back over time.
  • Clairvoyance: By crossing his eyes, he can see and listen things happening in other places. It only works if he's visited and seen the place before in real life. A similar power, "Psychic Photography", consists of concentrating in somebody or something during one minute to draw an illustration of its present location.
  • Dreaming of Things to Come: His dreams will occasionally warn him of future happenings.
  • The Empath: He can tell the affection rating of a person toward someone and illustrate it as percentage value in a heart-shaped digital display.
  • Equivalent Exchange: He can exchange something of another object of either equal or within a 10% difference monetary value.
  • Healing Hands: He has the power to heal wounds and injuries.
  • Invisibility: It takes a full minute of concentration to activate and lasts for 10 minutes. The effect is canceled if Saiki is touched by other people. Also, it doesn't works against people who can see ghosts.
  • I See Dead People: Saiki becomes able to see the ghost of Nendou's father, but not other ghosts as Reita, for unknown reasons.
  • Jedi Mind Trick: The "Mind Control" power. Although it serves only to convince people that something unusual is not really uncommon, it's actually Saiki's most dangerous power. If he convinces too many people that something is not unnatural, reality will actually change and not just that particular thing will become natural, it will cause a snowball effect that will affect a series of related things. Case in point, his world physics follows gag manga tropes in first place because he was careless with this power as a child.
  • Laser-Guided Amnesia: The "Memory Removal" power can erase up to one minute of memories by delivering a strong impact to the head of the target. The downside is that the brain of the victim will automatically fill the blank by creating a completely new memory that can't chosen. Also, because his Super Strength, Saiki needs use this power in combination with Restoration or the victim will die.
  • Living Lie Detector: Comes with being able to read people's minds.
  • Mass Hypnosis: Without his antenna shaped power limiter, Saiki's Mind Control ability spans all the world.
  • Master of Your Domain: Saiki has a great control over his body functions, from sweating freely to fool others into thinking that he's putting physical effort into races and sports activities to freely dislocate, contort and reassemble each one of his joints.
  • Memory-Wiping Crew: He can erase a specific memory from people's minds by hitting them in the head, which he sometimes does to protect the secret of his powers. Although, he can't choose the replacement fake memory.
  • Mind over Matter: Can use his mind to move people, objects, and even himself around.
  • Mundane Utility: Because he doesn't want to stand out, Saiki uses his powers for humorously mundane reasons like lifting shelves or going to the store.
  • Playing with Fire: Ranges from simply making objects feel hot to the touch to incinerating them to cinders.
  • Psychic Radar: Based in to estimate the distance and position of each mental voice. 200m range.
  • Psychometry: He can "see" an object's past by simply touching it; touching a person allows him to see and feel the same things they do in real time. Since it cannot be turned off, he constantly wears transparent gloves to prevent himself from seeing all of the unpleasant things associated with each object.
  • Self-Duplication: He develops the power of creating clones of himself because after several failed attempts, he realized only one of him isn't enough to stop the massive eruption of Mt. Owari. However, the clones are all have some form of Clone Degeneration, so most look like Gonk versions of Saiki.
  • Sex Shifter: Saiki's transformation ability lets him assume a female form known as Kusuko or Kuriko. He was born in the female form because his transformation powers were already active when he was in the womb.
  • Shock and Awe: Can summon lightning to just about anywhere he pleases.
  • Sizeshifter: He can shrink himself to a very small size; the effect lasts an hour.
  • Speaks Fluent Animal: He can communicate with animals using telepathy.
  • Spider-Sense: Has the ability to notice dangers and menaces before they happen.
  • Super Speed: Can reach Olympic level speeds with relative ease.
  • Super Strength: He has problems matching the strength level of ordinary people.
  • Taken for Granite: Why he wears his glasses. Anyone that looks directly at his eyes will turn to stone for a day.
  • Telepathy: Can't be shut off normally, causing him to have to constantly listen to others' thoughts within a 200 meter range. It doesn't work on Nendou for some reason, likely because he's an idiot. It can be shut-off by wearing a germanium-alloy ring.
  • Teleportation: He can teleport wherever he pleases, but it requires a three minute cooldown before he can use it again.
  • Time Master: The "Restoration" power can turn back the time for people and objects, bringing them to a prior state. The main downside is that other people and objects nearby may be accidentally affected too. When used on people, this power doesn't affect their memories.
  • Voluntary Shapeshifting: With his "Transformation" power, Saiki can change his form at will. He can turn into a woman, an animal or even aliens or inexistent beings. Completing the transformation takes two hours and has a ton of unmentioned downsides.
  • Weather Manipulation: He is able to part clouds and make the sun come out during a strong downpour.
  • X-Ray Vision: This power actives itself automatically after 5 seconds whenever he gazes at anything. A largely spreaded mistranslation claims that this power doesn't work against other telepaths, but that is wrong information The original source just compared its Power Incontinence with Telepathy.

Family Members

    Saiki Kuniharu

Voiced by:Mitsuo Iwata (Japanese), Chuck Huber (English Funimation), Michael Sinterniklaas (English Netflix), Arturo Mercado Jr. (Latin American Spanish)

Portrayed by: Seiichi Tanabe

Kusuo's father, a salaryman. Immature and greedy, he has fewer scruples about how his son should use his powers.

  • Bumbling Dad: As the resident Butt-Monkey, he tends to be a rather clumsy father.
  • Butt-Monkey: His main role in the series. Besides being very unlucky, he will usually suffer the consequences of his immaturity.
  • Extreme Doormat: He licks his boss' shoes (literally) whenever he commits a mistake or misses a deadline on his job.
  • G.I.R.L.: The RPG Episode shows he plays as a female character so he can join a party of better players who think his real life self is a girl too. Saiki ends up giving away his real gender when playing in his stand and his party leaves him.
  • Happily Married: To Kurumi, his lovely wife. He usually calls her "Mama". And despite all problems (that he usually provides), they will reconcile with each other at the end.
  • Hidden Depths: He's a passionate manga editor and even earns Kusuo's respect for how professional and passionate he is.
  • Just Think of the Potential!: His outlook on Kusuo's powers even ponders into things like burglary. He even calls his son "Kusuemon" when he gets into trouble and wants the help of his psychic powers.
  • Love at First Sight: He fell hard for his wife the moment he first saw her, comparing her to an angel.
  • Manchild: Acts very immature for his age.
  • Open-Minded Parent: He took the discovery of his son's power in stride.
  • Salaryman: His original job, though he was mostly licking his bosses' shoes. He seems to have changed from this to a manga editor, as it looked more comfortable.
  • Sickeningly Sweethearts: With Kurumi Saiki, to the annoyance of their son.

    Saiki Kurumi

Voiced by:Rikako Aikawa (Japanese), Morgan Garrett (English Funimation), Tara Sands (English Netflix), Isabel Martiñón (Latin American Spanish)

Portrayed by: Yuki Uchida

Kusuo's mother, an archetypal housewife. She is very nice and kind, if a bit naive, and raised her son to never use his powers for evil.

  • Almighty Mom: One of the only characters who can badger Saiki into doing things.
  • Beware the Nice Ones: Becomes physically violent when she's in an argument with her husband.
  • Beware the Silly Ones: Saiki actually becomes terrified when she suddenly insists that he hangs out with his friends at the beach.
  • Cannot Keep a Secret: She can't hold herself back from spilling the beans about Saiki's powers; it just slips out naturally in front of his friends or his friends' moms. She is terrible at covering her slip-ups and Saiki always has to intervene.
  • Comes Great Responsibility: Her outlook on Kusuo's powers is that he shouldn't use them for selfish reasons. Usually.
  • Extreme Doormat: It's almost impossible for her to say no to people and it takes practically noting to make her give in to persuasion. This causes her to buy a lot of useless stuff from door-to-door salesmen.
  • Full-Name Ultimatum: A variation. She uses the name "Kusuo" when angry, instead of the usual "Ku-chan".
  • Happily Married: To Kuniharu, whom she calls "Papa". Despite all adversities (and fights that she and Kuniharu may have), they will reconcile at the end.
  • Housewife: Usually stays at home and keeps the house tidy.
  • Like Parent, Like Spouse: Her husband and father are actually quite similar, though his father-in-law hides it under the facade of a Grumpy Old Man, being immature and silly and overly loving for their family.
  • The Maiden Name Debate: She didn't have to change her family name when she got married because her husband's family name is also Saiki.
  • Morality Pet: She's the only human being Kusuke ever treats kindly.
  • Nightmare Face: When really angry, her face becomes like a Hannya Mask.
  • Not So Weak: She gets very easily persuaded to buy useless stuff, but when Saiki uses telepathy to let her hear the salesman's thoughts, Kurumi puts on her Nightmare Face and chases after the salesman because he wants to leave her family poor.
  • Open-Minded Parent: She took the discovery of her son's power in stride. Her main concern was to teach him to not commit crimes with it.
  • The Pollyanna: Kurumi is very nice, optimistic, and she always thinks for the best of others. However, there are times that her good will crosses the line of Stupid Good.
  • Rescue Romance: She and her husband like to tell the story of how they first met when he defended her from a punk that was harassing her over and over. When Saiki accidentally travels to the past, however, Saiki discovers the "punk" was Nendou's father and the way his father acts makes it clear he probably "saved" his mother by accident.
  • Sickeningly Sweethearts: With Kuniharu, her husband, to the annoyance of their son.
  • The Tell: According to her mother, she hides her thumbs when she lies.
  • Unstoppable Rage: If pushed far enough, she will become really violent and chase her target to a massive beatdown.
  • Wrestler in All of Us: Subdues her husband with an array of wrestling moves when she's really angry.

    Saiki Kusuke

Voiced by:Kenji Nojima (Japanese), Chris Patton (English Funimation), Joe Zieja (English Netflix), Marc Winslow (Latin American Spanish)

Kusuo's elder brother by three years. He has a genius-level IQ of 218 but lacks Kusuo's psychic abilities, and thus constantly loses to him in challenges and feels inferior.

  • Big Brother Bully: Sort of. He tries very hard, but it's difficult to bully a little brother who has psychic powers and could destroy the world in three days. Kusuke's just fortunate that Kusuo wouldn't intentionally harm his family, no matter how much of an ass Kusuke is.
  • Bullying a Dragon: He has the nerve to insult Teruhashi, causing her to turn on the Crocodile Tears. This results in Kusuke being swarmed by a massive mob and having to escape via helicopter.
  • Competition Freak: A history of losing to Kusuo has caused him to constantly challenge and conflict with him, both for the thrill of messing with Kusuo and because he gets off on inevitably losing to him.
  • Even Bad Men Love Their Mamas: For all his nasty, sociopathic personality, Kusuke does seem truly fond of his mother at the very least.
  • Fantastic Radiation Shielding: Invented and wears a "Telepath Canceler" on his head that prevents Kusuo from telepathically reading his mind or controlling him, similar to Magneto's helmet.
  • Gadgeteer Genius: Is capable of inventing things such as mind-control prevention devices, drones, power armor, teleportation devices, youth restoration pods, and time machines, amongst others. On a passing whim.
  • Improbably High I.Q.: He has an IQ of 218.
  • Inferiority Superiority Complex: How he feels towards Kusuo. Despite being a genius capable of creating fantastic inventions, he lacks Kusuo's powers, and thus is constantly challenging him to prove his worth in some way.
  • Insufferable Genius: Believes himself to be above everyone else in the world (except Kusuo) and shows it.
  • It Amused Me: The primary reason why he messes with Kusuo the way he does.
  • Jerkass: He's a huge ass to Kusuo because of his own inferiority complex, and his attempts to one up Kusuo range from childish and obnoxious to being able to cause civilian casualties at worst if they weren't in a gag manga. One attempt to one-up Kusuo involved trying to kill him with a bomb in a coffee jelly box and then gloating about it.
  • My Friends… and Zoidberg!: Kusuo likes the rest of his family well enough, but he is constantly averse to and wary of Kusuke, referring to him as "that guy" internally.
  • No-Sell: In addition to his "Telepath Canceler" making him immune to Kusuo's telepathy, he is also immune to Teruhashi's charm and beauty.
  • Overshadowed by Awesome: As he himself notes, Kusuke possesses a superior intellect and was already incredibly accomplished as a child. However, his supreme talent is nothing compared to his brother's psychic powers. The funniest part is that no one knows he's being overshadowed since, unlike Saiki, he's open about his intellect to the public and lives a prestigious life, but the truth is what bothers him.
  • Peek-a-Bangs: His bangs cover one of his eyes.
  • Signature Headgear: He invented his own iconic head device to block off Saiki's telepathy.
  • The Sociopath: Played for Laughs, but he counts. Kusuke is a super genius who thinks of every other human being on the planet as stupid monkeys, which leaves him easily bored despite his ability to invent literally anything he wants. The one thing that brings him thrill is challenging his younger brother Kusuo to ridiculous games to test the latter's psychic powers, both because he loves annoying Kusuo out of jealousy over the latter's superhuman status and Kusuo is the only person in the world who can beat Kusuke at anything.
  • Successful Sibling Syndrome: Kusuke has a genius-level IQ of 218 and is one of the richest and most powerful people in the world through his company which sells his inventions, but yet he feels inferior to his younger brother, Kusuo, who has overwhelmingly powerful psychic abilities till a point it is not much of an exaggeration to call him a god if it wasn't for Power Incontinence. Kusuke keeps trying to challenge his younger brother with his inventions but always loses.
  • Troll: He gets off on messing with Kusuo and pretty much everyone around him.
  • Unwitting Instigator of Doom: In a specific Bad Future Kusuo arrives in via time travel, Kusuo somehow died, and Kusuke decided to invent a time machine in order to bring him back alive. However, the countries of the world ended up fighting over possession of this time machine, sparking World War III and reducing most of the world to smoldering ruins.

    Saiki Kumagoro & Kumi 

Kumagoro voiced by:Kōichi Yamadera (Japanese)

Kumi voiced by:Rie Tanaka (Japanese)

Saiki's maternal grandparents.

  • Age-Inappropriate Dress: Kumi dresses like a young woman.
  • Doting Grandparent: Kumagoro would absolutely be this if he weren't such a Tsundere. Kumagoro loves his grandsons and wants nothing more than to spend time with them.
  • Obnoxious In-Laws: Kumagoro genuinely hates his son-in-law Kuniharu.
  • Older Than They Look: Kumi is mentioned to look like she's in her forties despite having two grandsons in their late teens.
  • Shipper on Deck: Kumagoro thinks Kusuo and Teruhashi would make a good couple, while Kumi roots for Aiura.
  • Tsundere: Kusuo describes Kumagoro as a Harsh type word-for-word — he acts like a Grumpy Old Man around his family, but inwardly adores his grandsons and wishes they could spend more time together, often thinking like a girl with a crush whenever they're involved.

Saiki's Friends and Associates

    Nendou Riki

Voiced by:Kenta Miyake (vomic and flash anime) and Daisuke Ono (TV anime) (Japanese), David Wald (English Funimation), Jason Charles Miller (English Netflix), Dafnis Fernández (Latin American Spanish)

Portrayed by:Hirofumi Arai

"Come out and play! Heeey, are you there, pal?"

A really idiotic delinquent that thinks he is best friends with Saiki. He's actually a nice guy, but his stupidity and appearance cause his good deeds to backfire.

  • The Ace: When it comes to sports, or anything related to physical activity, no one is able to match Nendou, who pulls off athletic miracles effortlessly.
  • Adaptational Nice Guy: Nendou in the one-shots that the manga started as was Saiki's bully who forcibly copied Saiki's homework and was an all-around asshole. He only became Saiki's friend when Saiki stood up for him when he was framed for stealing someone's wallet. Nendou in the manga proper is a genuine Nice Guy who has never intentionally harmed anyone.
  • Affectionate Parody: Of the Dumb Is GoodBumbling Sidekick type whose positive demeanor won't shine through The Stoic Saiki.
  • Always Someone Better: In terms of physical abilities, he's this to Hairo, who can never catch up to him.
  • Badass Normal: Able to pull off tremendous feats of strength and speed. Unlike Saiki though, Nendou is more or less a completely normal human who just happens to be that physically strong.
  • Beautiful All Along: When he ends up with a normal hairstyle, his thuggish looks are instead hunkish, earning him the interest of girls, until he screws it up by picking his nose and eating it.
  • Best Friend: Considers himself as this to Saiki, much to Saiki's disagreement and chagrin.
  • Bread, Eggs, Milk, Squick: He lists all the bad things Saiko did to his friends and their families (sending Kuboyasu to jail, sending Saiki and Kaidou to Siberia, putting boogers on Nendou's comics) as revenge on Teruhashi for turning him down in this way.

    Nendou: Yeah, boogers, Siberia, or jail... they're no big deal!
    Kaidou:Placing our case on the same level as boogers is annoying, but he's right.

  • Characterization Marches On: The first couple of chapters have him drawn a bit more rugged with Saiki calling him a delinquent, likely a carryover from his portrayal in the one-shots where he was one. Later chapters would stray away from this portrayal, with Nendou instead being characterized as an incredibly dumb, but nice, guy with a Face of a Thug.
  • Crazy Jealous Guy: He never reacts well when Kaidou is popular with the girls, but they ignore him.
  • Crouching Moron, Hidden Badass: He is really athletic, can be a pretty decent person and is a great cook despite his stupidity.
  • Dead Guy Junior: His mother named him after his father who died in an accident before Nendou was born.
  • Delinquent Hair: Nendou has a blond mohawk with a strip of hair shaved around like a ring, that is noted to be such a terrible haircut that he looks better when forced to completely buzz his hair.
  • Disability Superpower: He's immune to mind-reading and telepathic detection because he's so stupid that he's never thinking anything at all. He's the only person who could sneak up on Saiki and theoretically kill him.
  • Dreadful Musician: His singing is bad enough to traumatize his classmates and knock them all unconscious.
  • Dumb Is Good: He's a very nice guy and he's as dumb as brick.
  • Dumb Muscle: Makes up for his low intelligence with his impressive strength.
  • Everyone Has Standards: He's not bright at all, but even he will mock Kaidou's antics as stupid on occassion.
  • Face of a Thug: He's a very nice guy, but most people are either scared or disgusted with him because of his looks. His hair is the worst part, as he morphs into a Hunk when his hairstyle is changed.
  • The Friend Nobody Likes: Due to his appearance, nobody wants to be around him.
  • Friend to All Living Things: Well, maybe not humans, but various animals seem to love Nendou due to how friendly and caring he is with them.
  • Gag Penis: Apparently his is big enough to intimidate Takahashi and his crew in an onsen to never make fun of him again.
  • Giftedly Bad: He clearly has no clue of how destructive his singing voice is. He even thought that all his classmates looked half-dead after hearing him play karaoke because his voice was so gentle that it put them to sleep.
  • Graceful Loser: He admits defeat when Kaidou beats him in air hockey which makes Kaidou feel guilty that he cheated.
  • Heroic Bastard: His mother had him when she was only 15 years old and his father was killed in an accident before he was born. Therefore, Nendou's parents could never get married and he has his mother's surname. While he's a big idiot, Nendou is a good guy.
  • Heterosexual Life-Partners: How he sees his relationship with Saiki. Saiki doesn't agree.
  • Hidden Depths: Nendou is a surprisingly capable cook, even if Saiki doesn't appreciate him making tuna crepes he knew what he was doing, and is a surprisingly good caretaker. For example, he takes excellent care of the hamster that Saiki gets him to take, performing actions such as knowing to leave some of the old shavings with her scent when cleaning the cage so she doesn't get confused.
  • Hollywood Tone-Deaf: His singing actually caused his class to faint. Kaidou stated it was like hearing death itself.
  • Identical Stranger: Downplayed, he looks nearly identical to the Baron Cola, the villain of a Kamen Riderish show.
  • Japanese Delinquents: He has the looks that would make anyone think he is a bad guy or a delinquent... except that he is very nice to people. And that he is very dumb.
  • Kindhearted Simpleton: What Nendou lacks (severely) in intelligence, tact, or common sense, he makes up for by being very caring and loyal to his friends.
  • Lightning Bruiser: Excluding Saiki's psychic powers, Nendou is physically the strongest and fastest of all the characters.
  • Like Father, Like Son: Saiki remarks that Nendou not only looks like his dad but even acts like him.
  • Mistaken for Pedophile: Kaidou mistook him for one once (he was out buying flowers, cake and watching young girls with their dads), when he was actually going to visit his father's grave, the flowers and cake were offerings, and seeing the kids with their dads reminded him of his own father.
  • Nice Guy: Or at least, he tries to be one. He truly is a nice guy, but his looks and intelligence make it hard for him to get the point across.
  • Nightmare Face: He can easily make these even when trying to smile.
  • Punny Name: "Nendou Riki" means "Telekinesis".
  • Slasher Smile: Fitting his face, some of his smiles look like this.
  • Strong Family Resemblance: His mother and father have the same chin, scars, and face as he does. His father looks exactly like him, hairstyle and all — it's the location of their scars what sets them apart.
  • Too Dumb to Fool: So dumb that Saiki can't read him.
  • Too Dumb to Live: Quite oblivious to the snake biting his crotch, but at least didn't bite through the fabric of his pants. If that wasn't enough, he declares that he doesn't need to be involved in a safety drill which causes Hairo to berate him for it.
  • Trademark Favorite Food: Ramen. He invites Saiki out to eat it regularly.
  • Vitriolic Best Buds: With Shun Kaidou, after both try to win Saiki's companionship.
  • When All You Have is a Hammer…: How does he aid an unconscious person? By beating the shit out of him.
  • World's Strongest Man: Again, excluding Saiki's psychic capabilities, Nendou is by far the physically strongest character in the series, beating out both Hairo and Kuboyasu.
  • Younger Than He Looks: He's 17, like the rest of the main cast, but he looks like he's in his late thirties at the youngest.

    Kaidou Shun

Voiced by:Takuya Eguchi (vomic and flash anime) and Nobunaga Shimazaki (TV anime) (Japanese), Micah Solusod (English Funimation), Zach Aguilar (English Netflix), Miguel Ángel Ruiz (Latin American Spanish)

Portrayed by:Ryo Yoshizawa

"I will protect the world! For I am the Jet-Black Wing!"

Shun Kaidou is the Secret Identity of Jet-Black Wing. Using the power of Black Beat, an godlike force imprisioned in his right arm, he fights to protect the world from the Dark Reunion, a Secret Society that plans to steal Black Beat and use its power to weed out the unnecessary elements from humankind and create a new world.

Or not. Actually, Shun Kaidou just believes he's Jet-Black Wing, and that Saiki is his sidekick in the fight against the Dark Reunion. Yeah, he suffers from Chuunibyou despite being sixteen.

  • Affectionate Parody: His appearance and the Jet-Black Wing's setup spoofs Battle Shounen stories.
  • Best Friend: With Kuboyasu, after discovering his delinquent past and being rescued from delinquents by him. Both get along well and are on First-Name Basis with each other. Kuboyasu also entertains his antics the most, such as when they made a secret hideout.
  • Book Smart: Kaidou tests rather well during Class Exams. It makes sense since it's later revealed that Kaidou has an Education Mama.
  • Calling Your Attacks: Even though he has no real attacks. He also uses this trope for mundane things.
  • Chick Magnet: He's actually decently popular with girls. Two girls tried to pick him up in the Beach Chapter and he even got a chocolate for Valentine's day. He even got Yumehara to like him during the school trip.
  • Chuunibyou: He's a Conspiracy Theorist who has a Secret Identity known as Jet-Black Wing, fighting to protect the world from the Dark Reunion. In actuality, it's implied that Kaidou f and only keeps up the antics as an outlet because he comes from an extremely strict household with an Education Mama.
  • Cloudcuckoolander: It's unknown how much he really believes in his own fantasies... although there are times that he gets lost in them while ignoring what is going on around him (especially when he gets into trouble) or he admits that it's just fantasies.

    Kaidou:[to a bunch of thugs] Huh? I thought I took you down. [..] Oh wait, that's my fantasy.

  • Coat Cape: Kaidou uses the jacket of his school uniform like this, since he believes he is some kind of hero.
  • Comical Overreacting: He has an exaggerated reaction to almost everything that he borders on being a Drama Queen:
    • His reaction to Nendou receiving a love letter is so over-the-top. He first has a Freak Out, then he throws up just because he finds it that unbelievable, then he goes into another Freak Out and starts picking his hair apart when Nendou considers turning the letter owner down all because, according to Kaidou, he doesn't have "the liberty to be picky."
    • He goes to the bathroom to cry when a snake shows up in their classroom out of nowhere.
  • Conspiracy Theorist: Claims that Dark Reunion is behind every bad thing that happens to him and his surroundings.
  • Cowardly Lion: In general, he'll stand up for his friends if pushed into a corner, but he doesn't have the brawn to back it up. For example, has the guts to protect his classmates from a runaway snake despite being utterly mortified while doing so. Even Saiki is impressed by this act of bravery.
  • The Cuckoolander Was Right: He's right about Saiki having powers, but not the way he expects. He tries to convince others that he saw Saiki float a book but no one ends up believing him when they find that nothing backs up his claims.
  • The Dog Bites Back: In the Valentine Day's chapter, Nendou tricks Kaidou into thinking he got chocolate from Teruhashi and then revealed it was a joke and then even mocked him over it. But Kaidou got the last laugh when a girl comes to their class to give him chocolate, he even takes the time to smirk in Nendou's direction.
  • Friend to All Children: He's so friendly around children that he'll temporarily snap out of his Jet-Black Wing persona while talking to them. He actually has no problem hanging out with them at a game room, though he gets super embarrassed when Nendou mocks him for it.
  • Good Eyes, Evil Eyes: Usually, his eyes are narrow and simplistic. Whenever he lets the Jet-Black Wing persona slip, they turn very wide and friendly.
  • Handwraps of Awesome: Invoked, since he wears them in order to appear tough. Supposedly, they seal Black Beat's power.
  • Height Insult: Since he's the shortest student in their class, Nendou and Saiko always call him "runt" and "tiny peasant" respectively. Although he only takes offense to being called poor.
  • Hidden Depths: He's actually smart and a few girls have expressed attraction to him, indicating he'd be a lot more popular if he dropped his Jet Black Wing act.
  • Hidden Heart of Gold: He acts arrogantly and pretentiously, but beneath his Jet-Black Wing persona, he's a nice guy.
  • I Just Want to Be Special: His deep desire to be seen as amazing and have people fawn over him is one of the reasons behind his Chuunibyou fantasies.
  • I Just Want to Have Friends: He desperately wants to make friends, even praying for friends on New Years. In one segment, he's conned into spending a huge amount of money on a necklace that will grant him a hundred friends. Later, he, Nendou, Saiki, and Kuboyasu form something of a friend group.
  • Incoming Ham: Whenever Kaidou is particularly hamming it up, his Leitmotif will start playing in the background; Judgement Knights of...
  • Inferiority Superiority Complex: He's rather timid, but it's hard for anyone to tell when he's acting like the arrogant Jet-Black Wing all the time.
  • In Touch with His Feminine Side: Kaidou is a pretty boy who's defined by his absolute lack of athleticism and physical strength, wimpiness in any heated confrontation (he immediately gives some Japanese Delinquents his wallet the moment they corner him), and how easily he bursts into tears over silly things or gets tongue-tied. His voice goes high-pitched whenever he's nervous, upset, or excited, as well.
  • Large Ham: He talks like a Battle Shonen protagonist and he's so loud all the time.
  • Lovable Coward: Despite how pathetic he acts in the face of trouble and Saiki being tired of seeing his lameness all the time, his friends still care about him and a few ladies even find him attractive.
  • Love You and Everybody: On the Valentine's Day Episode, Chiyo writes a love letter for Kaidou where she confesses that she likes him. The next day, Kaidou tells Chiyo he likes her too and accepts to upgrade their relationship… from friends to best friends because that's what he thinks the "code" in Chiyo's letter was asking him.
  • Miles Gloriosus: None of his exploits as the "Jet-Black Wing" ever actually happened. At least he's capable of being brave when he's in a pinch.
  • Mr. Imagination: Has a severe case of Chuunibyou, even though he is already in his second year of high school. He's convinced that in a previous life, he was a high level soldier of Dark Reunion who went rogue after he discovered their plans for world domination.
  • No Indoor Voice: He has a shouty voice in general, and since he treats everything like it's Serious Business, he's always yelling for no reason, sometimes out of nowhere.


  • No Sense of Direction: He's downright terrible at following directions and worst of all, he tends to guide himself and his friends into the worst possible places after getting lost.
  • Non-Action Guy: He pretends to be a competent fighter in his daydreams, but the truth is that unlike the other male characters (gifted athletes Hairo and Nendou, former gang leader Kuboyasu, and psychically strong Saiki), Kaidou is notoriously unathletic.
  • Non-Uniform Uniform: His uniform shirts and jackets are always slightly tattered, to reflect how he thinks of himself as some sort of urban fantasy shonen hero.
  • Obfuscating Stupidity: His hammy Chuunibyou persona is mainly a coping mechanism for his very strict lifestyle outside of school. Kaidou is really quite studious and well-versed due to being raised by an Education Mama.
  • Oblivious to Love: He's utterly clueless about Chiyo's blatant crush on him. On one occasion, he gets a love letter from her and he somehow ends up mistaking it for a hidden code that makes him think Chiyo wants to be his Best Friend instead of his girlfriend.
  • Opaque Nerd Glasses: His mom makes him wear those over the winter vacation alongside wearing a proper, zipped-up uniform and a nerdy side part in preparation for college. However, being a Gag Series, these changes are all gone by the end of the episode they appeared in.
  • Otaku: He regularly reads Shonen Jump magazine and has some sort of understanding of manga tropes as he remarks that Saiko having his servants at school is something out of a manga.
  • Pædo Hunt: Downplayed and it's caused by a misunderstanding on his side, but he gets squicked out when he sees Nendou look creepily at a child and goes on a brief tirade over how disappointed he is in him.
  • Peek-a-Bangs: Usually, only one of his eyes can be seen at a time.
  • Punny Name: A play on "Shunkan idou", or teleportation.
  • Running Gag: Him being physically weak, unathletic, and having a hard time doing anything that needs strength.

    His male classmates:[after seeing him throw a ball] He throws like a girl?!

  • Screams Like a Little Girl: He has a rather high pitched scream in the anime.
  • Secret-Keeper: He accidentally discovers Kuboyasu's violent habits and Kuboyasu then admits his delinquent past to Kaidou when saving him from some thugs. Kaidou protects Kuboyasu's secret and they become good friends.
  • Shonen Hair: It's very spikey, and likely intentional on Kaidou's part.
  • Small Name, Big Ego: He thinks he's so cool, acts cocky sometimes, and makes up stories about himself being all awesome especially to his little brother. However, he's actually nothing but a bluffing coward who desperately wants to impress others.
  • The Smart Guy: Due to his mom's strict academic upbringing, he is more or less the most well-read and knowledgeable of the group (outside of Saiki). This is most apparent when he suggests competing on a quiz game at the arcade with Nendou because he knows he'll definitely win in that area.
  • Super Drowning Skills: He can't swim, and he won't get into the water without wearing an unnecessary number of life preservers. It's revealed that he can swim fairly well if it isn't pointed out that he's swimming.
  • Terrible Artist: He tries to scribble down a picture of a child's lost dog based on its description. It ends up looking horrendous.
  • Tiny Schoolboy: Despite being 16, he doesn't even manage to scrape 5'3, and seems to be the shortest student in his class, girls included.
  • Vitriolic Best Buds: With Riki Nendou, after competing with him over Saiki's companionship.
  • Wrong Genre Savvy: Played for Laughs. He thinks he's The Chosen One of an urban fantasy battle shounen. In reality, he's a major character in a gag manga, so he just comes off as a tryhard nerd.

    Teruhashi Kokomi

Voiced by:Ai Kayano (Japanese), Tia Ballard (English Funimation), Kayli Mills (English Netflix), Georgina Sánchez (Latin American Spanish)

Portrayed by:Kanna Hashimoto

"Life is in 'very easy' mode. This is all because I am gorgeous."

The prettiest and most popular girl in school. Everyone falls under her charms, except Saiki.

  • A-Cup Angst: Well, while she isn't flat as indicated by the Beach Episode, she notices that one thing Aiura has her beat in is chest size. Funnier is that they're drawn with realistic highschool girl proportions, so the difference isn't that extreme.
  • The Ace: At least she thinks she's this, being beautiful, kind and a great singer.
  • Affectionate Parody:
    • Teruhashi is a Parody Sue. While she plays up the image of the pampered yet sweet beautiful girl who snags all the men she wants while seemingly being unaware of this, she is actually very aware of the power she has over the guys and hides her true thoughts to maintain the image of an ideal girl.
    • She's also a parody of the "hot girl seeks a mysterious loner" trope in that it's blatant that she likes Saiki since she can't control him with her looks.
  • Attention Whore: She revels in the attention people give her, to the point where she counts how many Oh wows she hears and is constantly figuring out how to increase the number. This is justified due to her being fawned over since birth.
  • Beautiful Singing Voice: Her classmates are moved to tears when they hear her sing karaoke and they all tell her she should become a singer.
  • Beneath the Mask: Beneath the saintly, stunning facade, she's constantly calculating how to maintain and improve her image. Only Saiki (and possibly his older brother Kusuke) is aware of this.
  • Betty and Veronica: The Veronica to Aiura's Betty with Saiki as the Archie. Teruhashi is the otherworldly beautiful School Idol who pretends to be the perfect girl when her real personality is incredibly egoistic. She could easily have any guy she wants, but instead focuses all her attention on Saiki, the one man who won't fawn over her. She gets frustrated when she sees Saiki hanging out with the Gyaru Girl Aiura and thinks he's only after the latter's boobs, but Saiki doesn't want anything to do with romance at all. But is a Dowplayed or Parodied example because Teruhashi is a Bitch in Sheep's Clothing, Aiura is more open about flirting and shows more skin than her (and other characters) and Saiki is not interested in romance.
  • Bitch in Sheep's Clothing: Teruhashi acts nicely and kindly, but she's manipulative and hides a deep contempt for her classmates. Saiki can see through the facade, in more ways thanone, though he's the only one that can do so, as she never drops it.
  • Book Smart: Kokomi ranks #21 out of 181 students in school exams.
  • Born Lucky: If Teruhashi wants something (except Saiki's affections), the heavens will conspire to give it to her. Even Teruhashi herself acknowledges this and use it to her advantage. Lampshaded by Saiki that his attempts to foil her luck always end up futile.
  • Calling Your Attacks: In desperate times she'll break out one of her "super moves" such as Angel Tears, which are just Crocodile Tears that cause all nearby bystanders drop what they're doing and rush to her aid.
  • Child Hater: Downplayed, she has a harder time with kids because her looks don't really affect them.
  • Class Princess: Invoked. Kokomi knows she has the entire school population (except Saiki) enamoured with her beauty. Instead of acting like an Alpha Bitch, she tries to maintain the image of being nice and kind because that makes others adore her even more. Later on, her interactions with Saiki and other classmates make her kindness more genuine.
  • Clingy Jealous Girl: She never likes it when other girls show interest in Saiki, especially when that girl is Aiura.
  • Closet Key: She unknowingly becomes one for Rifuta, who falls for both her and her brother.
  • Crocodile Tears: Her "secret weapon" is what she calls "Angel Tears," which she uses to send an angry mob at someone by pretending to cry.
  • Crush Blush: When Saiki mutes his powers in the Giga chapter, Teruhashi gets flustered and blushes when Saiki stares at her (unable to maintain her perfect exterior).
  • Curtains Match the Window: She sports matching navy blue hair and eyes.
  • Determinator: She will stop at nothing to maintain her image as the perfect girl, to the point that Saiki wonders if that does truly make her one.
  • Defrosting Ice Queen: Not that most people could tell she was icy on the inside, but her pleasant demeanour gradually stops being a facade over time as she gets closer to Saiki's friends. She's still very vain, but not so dismissive of 'regular' people.
  • Dude Magnet: Nearly every man she meets falls head over heels for her the second they meet her.
  • Even the Girls Want Her: It's downplayed for the most part. She's popular with her female classmates and there's a scene where two girls are staring at her with visible blushes. However, most of the girls at PK are shown to be explicitly straight and are also jealous of her beauty and popularity with men, as shown with Yumehara. It is eventually played straight though with Rifuta. Aiura also was attracted to her at first.
  • The Fake Cutie: On the outside, Teruhashi acts like the most lovable and purehearted girl ever, which makes everyone adore her even more. Saiki, who can see her inner thoughts, knows Teruhashi is just putting up a front to maintain her popularity as her real personality is narcissistic and manipulative.
  • Favors for the Sexy: Exploited. Teruhashi knows that guys will bend over backwards to do nice things for her because of how beautiful she is, and usually doesn't hesitate in taking advantage of this.
  • Feather Motif: When Aiura sees her aura, she notes that it is a cascade of angelic feathers, with a few black ones scattered in.
  • Freudian Excuse: Having been adored and fawned over for her cuteness since infancy, it makes sense as to why she would develop such an ego.
  • Gaussian Girl: Parodied. Teruhashi is so beautiful she actually has a golden aura surrounding her body at all times, giving off this effect. It extends to a larger, rainbow-colored one when she's feeling particularly happy and/or beautiful, and disappears when she's upset.
  • Gold Digger: Before growing interested in Saiki, she regularly stated she wanted to marry a rich man. Played with when she realizes that she doesn't need to marry rich since people just give her stuff. When the fabulously wealthy Saiko comes a-knocking she's mostly turned off by him but expresses interest in his wealth.
  • Head-Turning Beauty: When she's walking down the street, guys can't help but to stop whatever they're doing and stutter at her looks. Despite all appearances, she is very aware of this.
  • Honor Before Reason: Taharusa desire to always be seen as the perfect woman veers into this. When Nendou took her to some Lethal Eatery she refused to say she didn’t want to eat there. Even after Kaidou gave her an out by pointing out how disgusting the place was, she went in and ate its food.
  • Hopeless Suitor: Teruhashi is doomed to never win Saiki's love because he's firmly Asexual and majorly turned off by her narcissistic inner thoughts.
  • "I Am Great!" Song: Played for Laughs. She sings a hilarious one in episode 18 of the anime, where she mentions that she does have a Beautiful Singing Voice because she is a perfect beauty.
  • I Love You Because I Can't Control You: How she interprets her growing interest in Saiki, who seems to be the only guy immune to her charms.
  • Informed Attractiveness: In her introductory chapter and onward, she doesn't stop reminding the viewer of how beautiful she thinks she is, not that the actions of those around her do anything to dispute this fact. Teruhashi is drawn in the same style as everyone else, however; a golden aura is the only other thing that marks her as superhumanly attractive.
  • Jerk with a Heart of Gold: She starts off as a vain and self-centered Bitch in Sheep's Clothing who only wants attention. Later on, her crush on Saiki allows her to genuinely care for his friends rather than seeing them as annoyances, she refuses to use any other gimmick to attract Saiki, and it's clear now that her crush on Saiki has evolved beyond a shallow I Love You Because I Can't Control You.
  • Joshikousei: Her school uniform is the traditional Japanese Sailor Fuku.
  • Logical Weakness: Teruhashi's entire gimmick is that she's so beautiful that she captures the attention of most men and some women; she can then make them do her bidding. That said, this obviously doesn't work on everybody, with the exceptions including:
    • Children who haven't developed romantic attraction (like Yuuta).
    • People who aren't interested in women (as was suspected with Hairo).
    • People immune to letting love controlling them (as Kusuke invokes).
  • The Man Behind the Man: In the live-action movie, she masterminded the entire plot by recruiting her many admirers to keep Saiki's friends busy during the school festival by actively Exploiting their characters' quirks all in order to keep the Moment Killers out of the picture for a Shoujo GenreLocked in a Room scenario with Saiki.
  • Manipulative Bitch: She's great at attracting guys and making them do what she pleases.
  • Narcissist: Inside her mind, Teruhashi rarely stops going on and on about how she's the most perfect and beautiful Bishoujo on the planet. She adores being the center of attention, which is why she can't stand the fact that unlike other guys, Saiki isn't hopelessly smitten with her.
  • Oblivious to Love: She has no idea that her brother has feelings for her beyond familial.
  • Parody Sue: Teruhashi is a gorgeous young woman nigh-universally adored for her beauty, charm, and kindness. Beneath the Mask, she's manipulative and determined to maintain this image as much as she can, to Saiki's disdain. All of this is entirely Played for Laughs.
  • The Perfectionist: She won't allow herself to be anything but perfect.
  • Phrase Catcher: Whenever a guy excluding Saiki first sees her, they say "oh wow".
  • Proud Beauty: She pretends to be Obliviously Beautiful because that's more appealing, but she has really let all the praise from others go to her head and likes using her looks to make others do what she wants. That Saiki is the only man who doesn't say "oh wow" when he sees her is a big blow to her ego.
  • Punny Name: "Teruhashi" is a play on the word "telepathy".
  • School Idol: Easily the most popular student.
  • Sempai/Kohai: Exploited. She posits herself as Rifuta's sempai when the latter transfers to PK Academy by befriending her and giving her tips and advice. Everyone takes this as more evidence of Teruhashi's superior kindness and inner beauty, just as she intended — her motivation was to subtly put Rifuta in her place.
  • Slave to PR: Kokomi is hellbent on maintaining her public image of the "perfect Bishoujo". This is particularly the case when she is taken to a ramen shop. In order to keep from losing her image, she forces herself to eat spoiled ramen because she doesn't want others to see her acting rude by refusing the food.
  • Somebody Doesn't Love Raymond: Her interest in Saiki is initially because he doesn't fawn over her like every other guy, and she jumps through many physical and mental hoops to convince herself that he actually likes her deep down.
  • Spoiled Brat: Her entire life, people have gladly given Teruhashi anything she wants and more and showered with attention because she's beautiful. Inevitably, her ego got tremendously big as a result.
  • Took a Level in Kindness: Her crush on Saiki, as well as her friendships with the rest of the cast, make it so she does care about people other than herself. But she's still pretty spoiled.
  • World's Most Beautiful Woman: She's has been deemed the most beautiful woman on Earth from the moment she was born and people compare her to an angel or a goddess because no human can be that pretty.

    Yumehara Chiyo

"Saiki...even though I haven't spoken to you once yet...I always end up thinking about you like this..."

A hopelessly romantic girl with an unrequited crush on Saiki. She later falls for Kaidou.

  • Affectionate Parody: Of lovesick romance manga protagonists.
  • Crush Blush: She sports a furious blush whenever a guy does something for her and has it on throughout the time she thought she and Kaidou were officially an item.
  • Crush Filter: Whenever she gets a crush on a guy, she imagines him as a typical handsome Bishōnen love interest, complete with Bishie Sparkle and Gratuitous English subtitles like "LOVE FANTASY".
  • Curtains Match the Window: Light brown hair and eyes.
  • Formerly Fit: Gains a large amount of weight in between appearances, to Saiki's abject surprise. After he inspires her with the image of Kaidou's disapproval, she works off the weight very quickly.
  • Fourth-Wall Observer: Chiyo is the only character besides Saiki that knows she's in a manga/anime. She's pointed out how she's been Out of Focus at times, annoyed at the lack of attention her bikini reveal had to Teruhashi and Mera in the Class Trip and even whining the staff made her fat cause she's a Flat Character.
  • Hopeless Suitor: To Saiki, who isn't interested in her. All of her attempts to get close to him fail because he predicts every single move she makes. She eventually gets over him and falls for Kaidou instead, but her chances don't look that promising there either.
  • In Love with Love: It's very easy for her to fall for guys with the implication being she just wants to be in a relationship. Saiki compares her to a chick that imprints on the nearest thing.
  • Joshikousei: Her school uniform is the traditional Japanese Sailor Fuku.
  • Love Bubbles: Appear behind her whenever she's having a moment with a guy she's in love with or during her Imagine Spots.
  • Love Can Make You Gonk: Her face becomes really weird as she starts drooling and goes cross-eyed when she mistakenly thinks Kaidou reciprocated her feelings. Teruhashi describes it as "melting."
  • Loving a Shadow: Whenever she imagines Saiki, he appears as a very idealistic, BishōnenNice Guy love interest instead of the cynical, uninterested character that he is. It happens to her as well when she falls for Kaidou... sometimes, even worse.
  • Marked to Die: In one segment, Aiura notices the mark of death on Yumehara and she and Saiki work to keep her alive. After Saiki averts an accident involving Yumehara and a similarly-marked truck driver who'd fallen asleep at the wheel, the mark disappears.
  • Ms. Imagination: When she tries to lie about her weight, her monologue starts to approach Kaidou levels of ham.
  • Overshadowed by Awesome: How she feels when comparing her looks to Teruhashi. Given the disproportionate amount of male attention Terushashi receives, it's not exactly unjustified.
  • Punny Name: A play on "Yochi yume", or "premonition dreams".
  • Single Woman Seeks Good Man: She immediately crushes on anyone who acts manly in front of her or saves her from something:
    • She develops an instant crush on Toritsuka when he catches her before she falls in a forest at night and she concludes that he's dependable but quickly gets over it when he runs away the moment a wild boar appears.
    • She later falls for Kaidou when he stands up for her against some guys who were mocking her on the school trip.
  • The Social Expert: Yumehara is very good at making friends, easily able to win over some of the more anti-social characters.
  • Stock Shoujo Heroine: A parody of shoujo manga's lovelorn teenage protagonists. She would very much want to be one but circumstances and her own insecurities keep derailing her attempts.
  • Sweet Tooth: Yumehara enjoys sweets (though it isn't compared to Saiki's obsession to them), and she often worries if she gained weight or not (especially when she compares her own body to Teruhashi's).
  • Thinks Like a Romance Novel: In her introductory chapter, she constantly comes up with scenarios that put her and Saiki into over-romanticized situations. Saiki, who can see these thoughts perfectly, is not amused in the slightest.
  • Weight Woe: She's very worried about her weight, doesn't help she has a pretty big sweet tooth. At one point she becomes morbidly obese due to it and wouldn't have been able to work it off if Saiki hadn't caused her to think that Kaidou wouldn't be interested in her if she was fat, which forces her into overdrive and able to work off the weight in one day.
  • Wrong Genre Savvy: She Thinks Like a Romance Novel, and is introduced trying to set up cliche romance manga situations that would enable her to kickstart a romance with Saiki (whom she imagines as a stereotypical Bishōnen love interest). She's actually a character in a gag manga, and Saiki (who can read her thoughts) goes out of his way to defy her expectations.

    Hairo Kineshi

Voiced by:Satoshi Hino (Japanese), Kyle Phillips (English Funimation), Billy Kametz (English Netflix), Ferso Velázquez (Latin American Spanish)

Portrayed by:Hideyuki Kasahara

"People get stronger by exceeding their limits!"

The over-enthusiastic Class Representative. His enthusiasm infects everyone, except Saiki.

  • 100% Adoration Rating: Hairo's classmates adore him and are willing to go above and beyond for events like Sports Challenges and the School Festival just because he motivates them. Even Saiki finds it hard to half-ass things like he normally does just because of how passionate Hairo is.
  • Academic Athlete: Both a sports whiz and academically gifted.
  • Affectionate Parody: Notice a trend amongst the main student characters? He's a parody of hot-blooded, sports manga protagonists.
  • Ambiguously Gay: Chapter 135 has Kaidou and Kuboyasu and even Saiki curious over his sexual orientation due to the fact he's the only male besides Saiki to not care about Teruhashi's looks, he's very popular with men, is very physical in his rivalry with Nendou, and gets nude a lot. The chapter ends with the cast giving up trying to figure it out. In the end, Hairo admits he hasn't fallen in love before so he might be a case of ambiguously asexual.
  • Big Man on Campus: Is athletic, a Class Representative, a good student, and tries to improve everyone's wellbeing regardless of their background. Even Saiki admires him.
  • Chaste Hero: He seems to be the only guy, other than Saiki, not affected by Teruhashi's looks. Mostly because he's too focused on sports, he even admits he hasn't fallen in love before.
  • Class Representative: He's the class representative of Saiki's homeroom. As with everything he does, he's very proactive with his position.
  • Even the Guys Want Him: He's the most popular guy in his class, with most guys worshiping him due to his attitude. One guy even gave him valentine chocolate.
  • Fiery Redhead: Dark red and spiky hair, befitting his energetic personality.
  • Fist Pump: Does this when he's coming up with a plan, fired up to do something, or after he's accomplished something. He's just that enthusiastic about everything.
  • Genius Bruiser: Ranked in the top 10 during the School's Midterms.
  • Hot-Blooded: An exaggerated version of this trope. He is so hot-blooded that he can melt snow in a huge radius around himself in the middle of a cold winter just by standing there.
  • Infectious Enthusiasm: Hairo's charisma and popularity will inspire his classmates to give it their all in whatever activity he is currently doing or wants them to do. However, there are some times where Hairo's enthusiasm won't infect people.
  • Large Ham: He will even sweat dramatically without apparent cause.
  • Lovable Jock: Very athletic, and the most popular guy in the class, if not in the whole grade.
  • Manly Tears: Whenever he feels moved. There are times that he also inspires others to shed them.
  • Nice Guy: His hot-blooded passion for just about anything may come off as intense or annoying to some people, but he has a genuine desire to make others rise to their full potential. He's this trope to such an extreme degree that the first time Saiki walks home with him, Hairo carries an old lady to the station, directs a lost child and foreigner to it as well, cleans up vending machine trash, and stops a robbery (he succeeds on that last one due to Saiki's help, but the thought is there).
  • No Indoor Voice: Most of whatever comes out of his mouth is delivered in a loud, over-dramatic voice.
  • Non-Uniform Uniform: His uniform is sleeveless, even in winter.
  • Not So Above It All: Hairo can get too competitive to the point of willing to play dirty to win.
  • Pointless Band-Aid: He always has an adhesive strip on his nose to emphasize his athleticism.
  • Punny Name: "Hairo Kineshi" is a play on the word "Pyrokinesis".
  • Running Gag: His pants fall down whenever he trips.
  • Serious Business: Sports, teamwork, hard work, carrying heavy objects down a hallway are all serious things to him.
  • Shonen Hair: His hair is red and spiked up.
  • Sleeves Are for Wimps: Wears a sleeveless version of the school uniform even in winter as a visual reminder of his manliness and physicality.
  • Spirited Competitor: He even prayed for a rival that could push him to his limits on New Year! He even found one in Nendo.
  • Stock Shōnen Hero: A parody of the stock Sports Story hero — a spiky-haired, energetic young man who deeply believes in teamwork, hard work, and The Power of Friendship.
  • Testosterone Poisoning: His fiery obsession with hard work, determination, and pushing himself (and others) to ridiculous limits is so outlandish that it crosses into comedic territory.
  • Too Dumb to Live: He breaks down the shutter blocking the front entrance in a safety drill. The reason there was a shutter is because of the announcement that tells the science lab will be on fire; therefore it is a test to see if anyone listened to the announcement to go to the back entrance instead. Hairo sure didn't and ends up breaking down the shutter alongside Kaidou and Nendou.

    Saiki: In a real fire, they'd be the first to die.

  • Unknown Rival: Considers Nendou to be his sports rival after losing to him in 4 out 5 of the Fitness exams. Nendou being Nendou is completely oblivious to this fact.
  • Unusual Eyebrows: Slanted and kinked at the end.

    Toritsuka Reita

"I wanna master psychic powers so that I can do things like seeing girls' naked bodies and use precognition to win the lottery! I wanna live as I please!"

A high-schooler who was born the ability to see and talk to ghosts. He is aware that Saiki has psychic powers because a ghost told him so.

  • Brainwashed and Crazy: In the last episodes of the anime, Kusuke kidnaps him and brainwashes him to act as a weapon against Saiki. However, Kusuke acknowledges that it doesn't work because Toritsuka genuinely likes Saiki.
  • Casanova Wannabe: Would like nothing more than to be popular with women, but his attempts always fail (or at least never last that long) because of his own incompetence and pervertedness.
  • Crush Filter: When daydreaming about a fellow club member with Blinding Bangs, Toritsuka consistently imagines her as a cute girl, when it was previously shown that she was very plain under the bangs.
  • Dirty Old Monk: He was raised in a shrine, and is technically a monk-in-training. Ironically, he's the most perverted cast member.
  • Emergency Impersonation: Saiki uses his illusion powers so that his group of friends see Reita as him while he's busy trying to stop the eruption of Mt. Owari. He gets somewhat annoyed that all Reita needs to do is saying Saiki's Catchphrase to fool Saiki's friends.
  • Foil: For Saiki. While Saiki has regularly shown disdain for his powers, refusing to use them for his own benefit and overall trying to keep a low profile, Toritsuka is the exact opposite. He loves trying to use his powers for his own benefit which is usually to gain popularity.
  • Green-Eyed Monster: In the last episode of the anime, he briefly joins forces with Kusuke to hijack Saiki's body and take his powers for himself.
  • Guardian Entity: Has the ability to see each person's guardian entity thanks to his powers. His own personal guardian spirit is Nendou's lazy, deceased father.
  • I See Dead People: His special ability, which he's had ever since he was born, is to see ghosts.
  • Lovable Sex Maniac: Lampshaded by Saiki, who's surprised that someone can be so sincere and open about his own lewdness.
  • My Friends… and Zoidberg!: Unlike most of the other major students, who get plenty of Pet the Dog moments from him, Saiki doesn't like Toritsuka all that much and will go out of his way to ignore or berate him.
  • New Transfer Student: Transfers to Saiki's school the day after he introduces himself to him. Saiki complains that the development is way too cliched.
  • Non-Uniform Uniform: Wears colored shirts under his uniform jacket, as well as a headband and beads.
  • Punny Name: "Toritsuka Reita" is a play on "Toritsukareta", or "possessed" (as in, by ghosts).
  • Screw the Rules, I Have Supernatural Powers!: He regularly attempts to use his powers for his own benefit from trying to peep at girls to his heart's content, getting them to fall for him or cheating on tests.
  • Secret-Keeper: He is initially the only person aware of Saiki's powers, which he finds out about from ghosts telling him.
  • Useless Useful Spell: As a medium, Toritsuka is only capable of seeing and communicating with spirits. He doesn't actually know how to exorcise them.
  • Willing Channeler: Later he learns how to borrow the abilities of spirits by allowing them to possess him, at the risk of it being permanent.

    Mera Chisato

"Thank you so much, Saiki! I owe you my life! The truth is, I haven't eaten anything except ice since yesterday..."

A poor high schooler who is always starving and looking for something to eat.

  • Action Girl: Is easily able to hunt down snakes and other animals while on the island in the Shipwreck Arc and cut down trees even faster than Nendou and Kuboyasu. She also easily fends off hitmen hired by her father's debtees who try to capture her.
  • Badass Normal: The harshness of living in poverty has significantly hardened Mera, giving her extraordinary strength and speed in times of need.
  • Big Eater: Since she is very poor, when she gets invited to eat something (or when she sees food samplings), expect her to eat a lot of that.
  • Curtains Match the Window: Matching maroon hair and eyes.
  • Cute Clumsy Girl: Although she gives her best efforts in working as a part-timer in Café Mami, she often breaks the dishes in the process.
  • Damsel out of Distress: She has been hunted down and captured by her father's debtees, but every time she managed to escape and hunt them down instead.
  • A Fool and His New Money Are Soon Parted: Played for Laughs in the second season finale. Mera gains a fortune investing in bitcoin over vacation and acts like a tacky, social-climbing rich person. By the next day, the bitcoin market has crashed and she's back to being poor.
  • Girlish Pigtails: Her hair is tied into two low bunches.
  • Going Native: Played for Laughs. During the Shipwreck Arc, she goes absolutely feral to survive, running around like a Nubile Savage and hunting, losing the ability to talk until Teruhashi coaxes her back out.
  • Jack-of-All-Trades: She has several jobs to sustain her family — she works at the Café, as a morning newspaper and milk delivery girl, at the nighttime gas station, in a Chinese restaurant, in a diner, in a lunch shop, as a babysitter, at paper flower making, and tutoring... just to mention some of them.
  • Perpetual Poverty: All the income from her many, many jobs seems to go to her mother and siblings, and Mera never earns enough money to properly feed herself. She lampshades it when Akechi questions her.
  • Promotion to Parent: She's primarily responsible for feeding her younger siblings following her father's disappearance and her mother's illness.
  • Punny Name: One that gets Lost in Translation, but her name contains the kanji for "clairvoyance" ("senrigan").
  • Real Women Have Curves: Mera has a thicker frame than Teruhashi or Yumehara. Despite that, the series avoids going into Hollywood Pudgy territory. During the Beach Episode, Mera gets a longer glamour shot than the two other girls, with the male classmates admitting they love her curves.
  • Riches to Rags: Mera's family was originally filthy rich. One day, her dad's business went under and her entire family became extremely poor because of that. Not long after, Mr. Mera abandoned them and her mom got sick. And since she has little siblings, she is the only one who has to sustain her entire family on her own.
  • Triple Shifter: She's forced to work multiple jobs to support her entire family. Since working as a part-timer is forbidden for students in PK Academy, Saiki brainwashed everyone into thinking that PK Academy's students doing part-time jobs is perfectly normal to help her in keep maintaining her family.
  • Unwanted Gift Plot: Experiences this during her birthday episode, where she criticizes most of the numerous birthday gifts all her classmates give to her, to the point they get fed up with her ungratefulness and take their gifts back. She eventually gets better about it though.

    Kuboyasu Aren

Voiced by:Yoshimasa Hosoya (Japanese), Jarrod Greene (English Funimation), Kaiji Tang (English Netflix), Carlo Vázquez (Latin American Spanish)

"But the life of a normal person is tougher than that of a delinquent."

A former delinquent who wants to live as normal as possible when he is transferred to PK Academy.

  • Audience Surrogate: Kuboyasu's introduction episode had him reacting to the quirky students of Saiki's class much like an audience member would.
  • Badass Biker: He owns a motorcycle that he used to ride when he was with the Espers, his old gang. He still rides it from time to time.
  • Best Friend: With Kaidou after saving him from delinquents. Both get along well and are on First-Name Basis with each other. Kuboyasu also puts up with his antics such as when they made a secret hideout.
  • Blatant Lies: As a way to hide his punk habits, Kuboyasu tells very obvious lies to cover his acts in front of everyone, and they buy them (except Saiki, obviously). Once Kaidou finds out that Kuboyasu was a punk, he stops lying to him and his friends (Saiki and Nendou).
  • Blood Knight: He actually enjoys fighting.
  • Bully Hunter: Ends up beating the crap out of some delinquents who were trying to accost Kaidou.
  • Clark Kent Outfit: His physique looks average when he's wearing his school uniform. If he gets shirtless, you'll see his scarred and buff torso.
  • Covered with Scars: He tries to keep this hidden when getting dressed but, his cover gets blown when the other guys call him out on the fact that his body is covered in scars from the neck down. This only further convinces Kaidou that Kuboyasu used to be a punk.
  • Delinquent Hair: When he was still a gang leader, he had a mullet with long, floor-length hair.
  • Face of a Thug: Although his normal self's face looks very plain, if someone pisses him off, his face becomes very scary.
  • Former Teen Rebel: Kuboyasu is the former leader of a gang called the Espers. When he got sick of stepping on his own Rapunzel Hair, he decided to try and live like a normal student, but his habits never die as soon as he gets provoked to use his knuckles.
  • Hair-Trigger Temper: He tries his best to fit in PK Academy and tries to act normal, but he gets pissed off too easily by other people. In the case with Saiko, he has an innate hatred for him.
  • Hypocritical Humor: Accuses transfer students of being lame; Kaidou points out he was a transfer student himself.
  • I Just Want to Be Normal: He transferred to PK Academy to leave his delinquent past behind and become a normal student, although it's very hard to put his old habits behind him.
  • In the Blood: His parents were full-time delinquents (in their youth) like him, so he went through their same way of life as he grew a mullet.
  • Jerk with a Heart of Gold: Despite his former deliquent status, residual viciousness of his former lifestyle and his struggles to get along with his new classmates, Kuboyasu is actually rather levelheaded and nice, and ends up joining Saiki's circle of friends.
  • The Leader: Used to be this for a bike gang before transferring to PK Academy. In most situations, such as the Shipwreck Arc, he ends up being the leader of the group.
  • New Transfer Student: He comes from an all-boys high school that was full of delinquents just like him. One day, he realized that he was tired of stepping on his own (mullet) hair, so he wanted to graduate from being a punk.
