    Kusuo Saiki - Character Profile 
https://static.tvtropes.org/pmwiki/pub/images/saikik.png
"What a pain."
Voiced by: Shintaro Asanuma (vomic and flash anime), Hiroshi Kamiya (TV anime) and Haruka Tomatsu (Kusuko) (Japanese), Jerry Jewell and Jamie Marchi (Kusuko) (English)

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

The Main Character. 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.


  • Amazingly Embarrassing Parents: They lack a good deal of common sense and are Sickeningly Sweethearts.
  • Apocalypse How: His fear is unintentionally causing this.
  • Asexuality: Implied. Saiki claims that he has no interest in or understanding of romance, since he can read everyone's minds and can't see outer beauty. Romance tends to annoy him, especially when Teruhashi is involved.
  • 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.
  • 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).
  • Bishōnen: Not usually portrayed as one, but Yumehara imagines him as a typical handsome shoujo love interest in her Crush Filter, complete with Bishie Sparkle and Gratuitous English subtitles like "LOVE FANTASY".
  • 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.
  • 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: Because of his powers. X-Ray Vision + Telepathy = Apathy.
  • 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.
  • 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.
  • Does Not Know His Own Strength: If Saiki isn't careful, people will get hurt. Badly.
  • Fourth-Wall Observer: Saiki's inner monologue is specifically addressed to the reader, but he doesn't break the Fourth Wall aloud.
  • 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 Just Want to Have Friends: Inverted. He just wants to be alone, but his classmates keep trying be friends with him.
  • 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.
  • Leaning on the Fourth Wall: See 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.
  • 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.
  • 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: Possibly another of his psychic powers. 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.
  • 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.
  • 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.
  • Obfuscating Stupidity: He could easily become The Ace, but he doesn't want to stand out.
  • 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: 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 also 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.
  • 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".
  • Ridiculously Average Guy:
    • Invoked. 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 ridiculously average, 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.
    • Saiki idolizes Hiroshi Satou, a schoolmate who absolutely is this trope.
  • 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. And thanks to Comic-Book Time, they remain sophomores for quite a few in-universe "years".
  • Serious Business: Anything that he "doesn't dislike", but particularly sweets.
  • Shipper on Deck: He will happily pair Yumehara with any guy who isn't him, just so she will leave him alone.
  • Silent Partner: He has never been seen talking to another living being.
  • The Social Expert: An unconventional example, because despite preferring being left alone, his powers let him easily figure out what makes other people tick.
  • The Stoic: Constantly wears a bored, deadpan expression and rarely cracks a smile. Enhanced by his Stoic Spectacles.
  • 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: 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.
  • 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: 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.

    Kusuo Saiki - Psychic Powers 
Saiki has a big variety of powers, but every one of them is described as psychic in 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.
  • 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.
  • Gender Bender: Saiki's transformation ability lets him assume a female form known as Kusuko or Kuriko. In fact, though he was quite literally conceived as male he was actually born as a girl. He also doesn't seem to view his own gender as being particularly important to his identity, to the point that 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.
  • 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.
  • 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.
  • Shock and Awe: Can summon lightning to just about anywhere he pleases.
  • Size Shifter: 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.
  • Teleporters and Transporters: 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 .

Family Members

    Kuniharu Saiki 
https://static.tvtropes.org/pmwiki/pub/images/kuniharu.png
Voiced by: Mitsuo Iwata (Japanese), Chuck Huber (English)

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.
  • Fantastically Indifferent: He took the discovery of his son's power in stride.
  • 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.
  • 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.
  • Like Parent, Like Spouse: Although his father-in-law hates him, they 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.
  • Manchild: Acts very immature for his age.
  • 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.

    Kurumi Saiki 
https://static.tvtropes.org/pmwiki/pub/images/kurumi_1.png
Voiced by: Rikako Aikawa (Japanese), Morgan Garrett (English)

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 to 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.
  • Comes Great Responsibility: Her outlook on Kusuo's powers is that he shouldn't use them for selfish reasons. Usually.
  • Fantastically Indifferent: She took the discovery of her son's power in stride. Her main concern was to teach him to not commit crimes with it.
  • 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.
  • Nightmare Face: When really angry, her face becomes like a Hannya Mask.
  • The Pollyanna: Kurumi is very nice, optimistic, and she always thinks on the best of others. However, there are times that her good will crosses the line of Stupid Good.
  • 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.

    Kusuke Saiki 
Voiced by: Kenji Nojima (Japanese), Chris Patton (English)
https://static.tvtropes.org/pmwiki/pub/images/kusuke.png

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.
  • Combat Sadomasochist: Well, without actual physical combat. 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.
  • 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.
  • 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 for why he messes with Kusuo the way he does.
  • Jerkass: He's a huge ass to Saiki because of his own inferiority complex, and his attempts to one up Kusuo range from childish and obnoxious to could cause civilian casualities 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. Though in the case of the latter this turns into him Mugging the Monster by insulting her, and causing her to, or at least pretend to, cry, causing him to be swarmed by a massive mob and having to escape via helicopter.
  • 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.
  • Peek-a-Bangs: His bangs cover one of his eyes.
  • Troll: He gets off on messing witk 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.

    Kumagoro & Kumi Saiki 
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 this word-for-word — he runs cold to his family, but inwardly adores his grandsons and wishes they could spend more time together.

Saiki's Friends

    Riki Nendou 
https://static.tvtropes.org/pmwiki/pub/images/nendou.png
Voiced by: Kenta Miyake (vomic and flash anime) and Daisuke Ono (TV anime) (Japanese), David Wald (English)

"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.
  • Affectionate Parody: Of the Dumb Is Good Bumbling 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.
  • Biggus Dickus: Apparently enough to intimidate Takahashi and his crew in an onsen to never make fun of him again.
  • Crouching Moron, Hidden Badass: He is really athletic, can be a pretty decent person and is a great cook despite his stupidity.
  • 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.
  • Disappeared Dad: His father died before he was born. He was killed while saving a little girl from an oncoming truck.
  • 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.
  • Green-Eyed Monster: He never reacts well when Kaidou is popular with the girls but they ignore him.
  • 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, performimg 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 bit 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.

    Shun Kaidou

Voiced by: Takuya Eguchi (vomic and flash anime) and Nobunaga Shimazaki (TV anime) (Japanese), Micah Solusod (English)

"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.


  • Adorkable: Tends to come up more after learning about his home life, when the Jet-Black Wing persona falls flat, and whenever female classmates start hitting on him.
  • Affectionate Parody: His appearance and the Jet-Black Wing's setup is an In-Universe Cliché Storm from the Battle Shounen genre.
  • Big Brother Worship: Kaidou's younger brother adores him and thinks his exploits as the Jet-Black Wing are all real.
  • 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.
  • 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).
  • Coat Cape: Kaidou uses the jacket of his school uniform like this, since he believes he is some kind of hero.
  • 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 in the way he thinks.
  • Ditzy Genius: Despite all of his antics, Kaidou actually tests rather well during Class Exams. It makes sense since it's later revealed that Kaidou has an Education Mama.
  • The Dog Bites Back: In the Valentine Day's chapter, Nendou tricks Kaidou into thinking he got a 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 a 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.
  • 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.
  • 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: Chuunibyou is caused by this.
  • I Just Want to Have Friends: He desperately wants 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 Kaiduo 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.
  • Large Ham: He talks like a Battle Shonen protagonist.
  • Miles Gloriosus: None of his exploits as the "Jet-Black Wing" never 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.
  • 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.
  • Peek-a-Bangs: Usually, only one of his eyes can be seen at a time.
  • Punny Name: A play on "Shunkan idou", or teleportation.
  • Shonen Hair: It's very spikey, and likely intentional on Kaidou's part.
  • The Smart Guy: Due to his mom's strict academic upbringing of him, he is more or less the most well-read and knowledgeable of the group (outside of Saiki).
  • 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: 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 wimpy nerd.

    Kokomi Teruhashi 
https://static.tvtropes.org/pmwiki/pub/images/teruhashi.png
Voiced by: Ai Kayano (Japanese), Tia Ballard (English)

"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.


  • The Ace: At least she thinks she's this, being beautiful, kind and a great singer.
  • 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.
  • Affectionate Parody:
    • Teruhashi is a Parody Sue. While she plays up the image of the Spoiled 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.
  • Awesome Ego: While she is really cocky about her beauty, the series has shown that she has every reason to think that. Nearly every man she meets falls head over heels for her the second they meet her. When she visited an aquarium, the fish circled around her.
  • 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.
  • 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 than one, though he's the only one that can do so, as she never drops it.
  • 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.
  • Character Development: She starts out as something of a Bitch in Sheep's Clothing, but her crush on Saiki has allowed her to genuinely care for his friends rather than seen them as annoyances, she refuses to use any other gimmick to attract Saiki and it's clear now that her crush on Saiki have evolved beyond a shallow I Love You Because I Can't Control You. 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) and the thoughts Saiki can't read are genuine love.
  • Child Hater: Downplayed, she has a harder time with kids because her looks don't really affect them.
  • Closet Key: She unknowingly becomes one for Rifuta, who falls for both her and her brother.
  • Curtains Match the Window: 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.
  • 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
  • Failure Is the Only Option: Double subverted in that nothing Saiki will do can foil her luck or her crush on him, but Teruhashi is doomed to never win Saiki's love and her obsessions only grow crazier.
  • 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.
  • Femme Fatale: She's great at attracting guys and making them do what she pleases.
  • 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.
  • Hello, Nurse!: Possibly the World's Most Beautiful Woman. In her presence, guys can't help but to stutter at her looks.
  • "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.
  • 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 Genre Locked in a Room scenario with Saiki.
  • 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.
  • Phrase Catcher: Whenever a guy excluding Saiki first sees her, they say "oh wow".
  • 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: Instead of acting like an Alpha Bitch, she tries to maintain the image of being nice and kind. 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.
  • 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 true self. She can't stand the fact that unlike other guys, Saiki isn't hopelessly interested in her.
  • Spoiled Sweet: Her facade is that of an impossibly beautiful and kind young woman.
  • 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.
  • What Does She See in Him?: Rifuta's reaction to her interest in the seemingly average Saiki, since Teruhashi is so far out of his league by in-universe standards.

Voiced by: Yukari Tamura (Japanese), Jill Harris (English)

"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: To lovesick romance manga protagonists.
  • Crush Filter: Whenever she imagines Saiki, he appears as a very idealistic, Bishounen 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.
  • 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.
  • Hair Decorations: Wears a headband.
  • 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.
  • 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.
  • 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.
  • Mr. Imagination: Gender flipped example, when she tried 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 later falls for Kaidou when he stands up for her in the school trip.
  • 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.

    Kineshi Hairo 
https://static.tvtropes.org/pmwiki/pub/images/hairo.png

Voiced by: Satoshi Hino (Japanese), Kyle Phillips (English)

"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 a valentine chocolate, and he wasn't amused by it.
  • 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 his body sweats heat in the middle of a cold winter.
  • 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...
  • 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.

Voiced by: Natsuki Hanae (Japanese), Joel McDonald (English)

"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.


  • 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.
  • 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.
  • 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.
  • Loveable 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.
  • Nonuniform Uniform: Wears colored shirts under his uniform jacket, as well as a headband and beads.
  • Not So Different: When his psychometry forces him to see what Toritsuka has to see every day, Saiki sympathizes with his situation.
  • 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: Aside from family (and later Aiura), he is initially the only person aware of Saiki's powers.
  • 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.

Voiced by: Maaya Uchida (Japanese), Megan Shipman (English)

"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 that is forced to work part-time to support her entire family. Since working as a part-timer is forbidden for students in PK Academy, Saiki brainwashed everyone in thinking that part-time jobs (at least for PK Academy's students) was very normal (after she was found out by their homeroom teacher, Matsuzaki), to help her in keep maintaining her family.


  • 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.
  • Disappeared Dad: Her father walked out on them, leaving her to care for her mother and siblings. He shows up later in the series.
  • 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.
  • 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: Is 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.
  • 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.

Voiced by: Yoshimasa Hosoya (Japanese), Jarrod Greene (English)

"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.
  • 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.
  • 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.
  • 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.
  • Heterosexual Life-Partners: With Kaidou. Both get along well and are in first name basis with each other. Kuboyasu also puts up with his antics such as when they made a secret hideout.
  • Hidden Depths: Just like Nendou, he is a surprisingly good cook.
  • Hypocritical Humor: Accuses transfer students of being lame; Kaidou points out he was a transfer student himself.
  • I Just Want to Be Normal: The reason he transferred to PK Academy, although it's very hard to put his old habits behind him.
  • Japanese Delinquents: Kuboyasu used to be a delinquent, but his habits never die as soon as he gets provoked to use his knuckles. He is the former leader of a gang called the Espers, and his parents were also full-time delinquents (in their youth) like him, so he went through their same way of life as he grew a mullet.
  • 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.
  • Nice Guy: Despite his former Deliquent status 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.
  • Nonuniform Uniform: Inverted. Unlike the other male characters except Saiki, he wears his uniform strictly to the letter. Akechi interprets this as someone trying too hard to look respectable, which fits with his conclusion of Kuboyasu being a reformed delinquent.
  • No Social Skills: Due to his history as a delinquent, he has no idea how regular people act at all. Though this becomes downplayed over the course of the series, as he evolves into the Only Sane Man.
  • Offhand Backhand: Uses this fighting technique to deal with some delinquents.
  • Only Sane Man: He occasionally takes this role, since Saiki is never quite vocal about his opinions. Unfortunately, Kuboyasu has his own quirks that make him Not So Above It All at times.
  • Punny Name: "Kuboyasu Aren" is an anagram for the Japanese spelling of the English word "clairvoyance" ("kureaboyansu").
  • Purely Aesthetic Glasses: His vision is fine; his glasses are non-prescribed and purely part of his attempt to transition away from being a delinquent and become a normal person
  • Rapunzel Hair: He grew a mullet ever since he was a kid. By the time he was 15, it was long enough to reach the floor. A deconstruction too; Kuboyasu got sick of constantly stepping on it.
  • Younger Than They Look: His former look as a delinquent made him look older than he was supposed to be (15 years old). If he gets shirtless, his scarred and buff torso would agree with that statement as well.

Voiced by: Masaya Matsukaze (Japanese), Adam Gibbs (English)

"Let's get something straight. I don't intend to be friends with you commoners."

A fantastically rich corporation heir who transfers to PK Academy with the intention of wooing Teruhashi. This goes about as well as you'd expect.


  • Affectionate Parody: Of rich jerks who are used to buying their way through life.
  • Big Fancy House: Of course, as the resident wealthy character, his estate is incredibly large.
  • Break the Haughty: During the shipwreck arc, he refuses to slum it with the other students and their "plebeian" food and winds up nearly starving for two days.
  • Bullying a Dragon: Even without getting into the guy with Psychic Powers, bullying the girl with a fanbase spanning a large number of students turned out to be a really bad idea.
  • Curtains Match the Window: Gray hair and eyes.
  • Fiction 500: Parodied. He's so fantastically rich that he can give away millions of yen at the drop of a hat, sits in a tub of bills, and has a throne made of stacks of money. In one episode, he completely remodels his mansion to include an amusement park, a beach, an incredible game room and bar, and a room full of sweets all on a whim. Even discussed, as Saiki compares him to a very wealthy comic book character.
  • Freudian Excuse: Yeah, he's a real jerk who loves to invoke Screw the Rules, I Have Money! but that's because his father taught him that "there's nothing in this world that money can't buy" and he had no reason to think otherwise until joining PK Academy.
  • I Just Want to Have Friends: It's vaguely implied that this is the reason he went out of his way to win the approval of Nendou, Saiki, Kaidou, and Kuboyasu by remodeling his entire estate to suit their interests.
  • It's All About Me: When it turns out that the class wasn't doing the School Play ending that put Saiko front and center, he pulls out all his financial support.
  • Jerkass: After Teruhashi rejects him because she likes Saiki, he decides to move Saiki's family to Siberia and create rumors to start a scandal surrounding her brother so that she truly is penniless.
  • New Transfer Student: Transfers into Saiki's class.
  • Not So Different: With Teruhashi. Both were raised under a certain principle that they believed was absolute until meeting a member of Saiki's group who were so different that they had to rethink these beliefs.
  • Poke the Poodle: He tries to pressure Teruhashi into dating him by making her life and the lives of those around her miserable. While this includes serious efforts like nearly transferring Saiki and Kaidou to Siberia, it also includes leaving laxative bread outside Mera's house (which she enjoyed eating anyway).
  • Punny Name: One of the most straightforward. "Saiko Metori" sounds like "Psychometry."
  • Screw the Rules, I Have Money!: His defining trait. He honestly believes that money can buy anything.
  • Spoiled Brat: Saiko is used to paying everyone to get exactly what he wants, but he runs into a wall with the PK Academy students, who just find him insufferable.
  • Token Rich Student: Neither the school nor the gaggle of students the story follows are mentioned to be particularly well off...except for Saiko. He's heir to a ridiculously rich family, who constantly flaunts his wealth and sticks up his nose at the "commoners" surrounding him. His given reason for slumming it when he could obviously afford much better is that he intends to woo Teruhashi.

    Imu Rifuta

Voiced by: M.A.O.

"No...! There can't be someone cuter than me!"

A beautiful freshman who transfers to PK Academy with the intent of making all the guys fall for her. Again, given Teruhashi's presence, this goes about as well as you'd expect.


  • Always Second Best: She might be leagues more beautiful than the average girl, but everyone agrees that Teruhashi still has her beat.
  • Bi the Way: Turns out her feelings for Teruhashi are romantic in nature, but she still likes boys even gaining a crush on Makoto Teruhashi.
  • Break the Haughty: It's implied that she was the most popular girl in her middle school and she plans to do the same at PK Academy. Seeing that Teruhashi was already more popular than her really damages her pride.
  • The Cutie: Invoked and subverted. She puts on a cute act in order to gain the attention and control the guys around her. She is really a Bitch in Sheep's Clothing, like Teruhashi.
  • Fangirl: She becomes a huge fangirl of Makoto Teruhashi, when she realizes he's a male Kokomi lookwise.
  • Girlish Pigtails: Wears her hair in two pigtails, which are noted to make her look cuter.
  • Hair Decorations: Her elastics have charms on them, fitting with her image as The Cutie.
  • Hello, Nurse!: Guys tend to fawn over her when she passes by. However, guys consider her less beautiful than Teruhashi, much to her chagrin.
  • New Transfer Student: She is introduced when she transfers into the school.
  • Punny Name: "Rifuta Imu" is a play on the Japanese pronunciation of "time leap".

    Mikoto Aiura 
https://static.tvtropes.org/pmwiki/pub/images/aiura.png
Voiced by: Eri Kitamura (Japanese)

"When I meet him I should definitely be able to tell by his aura... but I am definitely going to find him."

A Gyaru Girl who also possesses psychic powers, mostly in the vein of fortune telling and aura vision. She transfers into the school because her fortune said that a psychic with the initials "S.K." at PK Academy is her Mr. Right. Saiki is unamused.


  • Ambiguously Bi: Her crush on Saiki is made very clear, but it's implied she may be interested in Teruhashi as well. Aiura blushes during their first meeting and even says that Teruhashi is cute.
  • Ambiguously Brown: She is dark skinned with blonde hair, but has a Japanese name. A flashback in the anime shows her once to have been a fair brunette, and she is seen with brown hair once she tries a normal look.
  • Aura Vision: She can see people's auras, except when she's around Saiki (because his aura is so big he blocks everyone else's).
  • Buxom Is Better: Has the largest bust of Saiki's female friends. When she first transfers in, the guys note that she might not be as beautiful as Teruhashi, but her big rack kind of makes up for it.
  • Dark-Skinned Blonde: Close, fitting her being a gyaru. She has dark skin and yellow-green hair.
  • Fortune Teller: She can tell peoples' fortunes and does so with a crystal ball and various other incomprehensible rituals. Saiki confirms that her powers are the real deal.
  • Gyaru Girl: She is noted to have this aesthetic; she's dark-skinned with light hair, energetic, and fashionable.
  • Ms. Fanservice: Not as "beautiful" as Teruhashi but certainly curvier and shows off more skin. She's also more open while flirting.
  • Nice Girl: Despite being a bit crass, she is very easygoing and quickly befriends most of the class. She also often goes out of her way to help her friends, such as Saiki, Chiyo, and Mera.
  • New Transfer Student: Yet another transferee into Saiki's class.
  • The Nicknamer: For example, she calls Yumehara "Chiyopipi" and Mera "Chisapoyo."
  • Pet the Dog: Buys Mera a rice omelette while at the maid cafe she works at, to give her a chance to relax and eat real food with friends. Afterwards, she also helps Mera reunite with her father.
  • Secret Keeper: Like Toritsuka, Saiki lets her know about his powers because she is supernatural herself.
  • Shameless Fanservice Girl: Her uniform violates several rules by showing her cleavage and long legs. When Saiki also asks for a favor, Aiura interprets this as a sexual one and quickly jumps into bed naked.

    Touma Akechi

Voiced by: Yuki Kaji

"Yes, [Saiki] and I were classmates in elementary, albeit only up to second grade. So I'm curious as to what kind of person he's become..."

Another transfer student. Akechi was Saiki's classmate in elementary school and is determined to find proof of Saiki's powers. He's also an exceedingly fast talker.


  • Badass Normal: Toritsuka and Aiura begrudgingly accept him among the "PK Psychics" after his powers of deduction prove more useful than their actually supernatural abilities.
    • And whereas Toritsuka managed to figure it out with help of ghosts and Saiki was forced to reveal herself to Aiura, Akechi managed to corner Saiki into revealing himself.
  • Bait-and-Switch: He's led up to be someone malicious who could possibly expose Saiki's powers. Once Saiki gives up on changing the past so Akechi never suspects him and lets him in on the secret, Akechi tells him that he just wanted closure on the incident and vows to never reveal his secret.
  • Motor Mouth: Big time. He talks so fast that his sentences overlap. He even lampshades that it's his gimmick.
  • New Transfer Student: Another transferee. By the time of his introduction, the class is so sick of this trope that they're uninterested.
  • Punny Name: A pun on the Japanese word for invisibility.
  • Secret Chaser: Wants to find out if Saiki really does have powers, and goes to extreme lengths for it. Once Saiki lets him in on the secret, he becomes a Secret Keeper.
  • Sherlock Scan: Akechi is very observant and good at deductive reasoning. For example, he managed to figure out that Kuboyasu was a former delinquent immediately. He notes that his glasses, hair, and proper uniform was something he used to make himself presentable but his manner of speaking and muscles were a dead give away.
  • Stalker Without a Crush: Tailed Saiki for six months in order to find oddities that could prove Saiki is a psychic.

Other Students

    Takahashi 
Voiced by: Taishi Murata (Japanese), Travis Mullenix (English)

A recurring side character. Typically unlucky and on the butt end of situations, as well as another nuisance for Saiki to put up with.


  • Butt-Monkey: Frequently on the butt end of all situations he is in.
  • My Friends... and Zoidberg: Not that he's even really friends with Saiki, but he regularly gets treated like trash in almost all his appearances.

    Arisu Makino 
Voiced by: Nozomi Furuki

The sole member of the occult club outside of the main cast.


  • Beautiful All Along: After a receiving a makeover from Chiyo, she is actually remarked upon as being quite attractive. Even Saiki thinks she looks like a completely different person.
  • Blinding Bangs: Her hair covers her (rather plain looking) eyes.
  • Sphere Eyes: Has these as opposed to the typical Big Anime Eyes everyone else has, much to Toritsuka's disappointment.
  • The Makeover: Courtesy of Chiyo.

    Manako Jouten 
Voiced by: Azusa Enoki

The unscrupulous president of the Newspaper Club.


  • Beauty Mark: Beside her right eye.
  • Punny Name: A play on "Joutengan", or clairvoyance.
  • School Newspaper News Hound: Her role. She will do anything for a good story and hounds the cast following the shipwreck arc in the hopes that they'll get a good scoop. She'll even scoop to spreading slander, fake news, and manipulated images to further this end.
  • Worst News Judgement Ever: Since she finds Saiki's account of the shipwreck boring, she (for some reason) instead tries to spice it up with a picture of Teruhashi pooping, and headlines the paper's next issue with this.

    Satou Hiroshi 
Voiced by: Kensho Ono

A very normal student that Saiki idolizes.


  • The Generic Guy: So much in fact, Toritsuka notes how abnormally normal he is.
  • Generic Name: His name is completely normal and generic.
  • Ridiculously Average Guy: Exaggerated to an extreme degree. He is thoroughly average in grades, physical exams, and appearance. He has a completely normal name, backstory, personality, friend group, interests, and reactions to situations. It is for all these reasons Saiki idolizes him.

The school's PE instructor.


  • Reasonable Authority Figure: Although he has a bad rep with the students, he genuinely looks out for their well-being and wants the best for them. He waits all night to gently shut down a student he thinks is interested in him and compliments Mera on her parttime job.
  • Stern Teacher: By reputation, he's a "bad cop".

    Kyouka Shima

Other Characters

    Kouta Nakanishi 
https://static.tvtropes.org/pmwiki/pub/images/nakanishi.png
Voiced by: Showtaro Morikubo (Japanese), Austin Tindle (English)

A businessman-turned-wannabe stage illusionist who performs under the stage name "Chouno Uryoku". He has seen some of Saiki's powers, but chalks them up to Saiki also being a magician.


  • Catchphrase: "AMAZING!" when performing his tricks.
  • Curtains Match the Window: Green hair and green eyes.
  • The Ditz: Tends to make questionable leaps in logic (he thinks that since he made his career and wife disappear, he can translate this into being an illusionist who can make things disappear), and is horrible with money (such as deciding to spend over a million yen on a secondhand stage magic device).
  • One Degree of Separation: It turns out his ex-wife Midori is Nendou's mother. Saiki complains about the writing when he realizes this coincidence.
  • Punny Name: His real name is a play on "Naka ni Shikonda", a phrase meaning "hidden within". His stage is basically the word "Chounouryoku", meaning ESP.
  • Stage Magician: Post-career change, he's a magician who performs things for a live audience. The series explains his tricks.

    Riki Takeuchi 
Voiced by: Daisuke Ono (Japanese)

Nendou's deceased father, now Toritsuka's guardian spirit. For some reason, he is visible to Saiki even without Toritsuka's powers.


  • Friendly Ghost: Although a bit uncouth, he shares Nendou's base personality (cheery friendliness). Saiki finds him annoying, though.
  • Ghost Amnesia: He doesn't remember that Nendou is his son, but hangs around him anyway because he's curious about him.
  • Lookalike Lovers: With Nendou's mother Midori, who has the exact same face as him and their son.
  • Strong Family Resemblance: He is the absolute spitting image of Nendou, the only difference being which eye their scars are over.

    Midori Nendou 
https://static.tvtropes.org/pmwiki/pub/images/profile_midori.png
Voiced by: Daisuke Ono (Japanese), David Wald (English)

Nendou's mother and the widow to Takeuchi.


  • Teen Pregnancy: She reveals to Kurumi and Kaido's mother that she was 15 when she gave birth to her son.
  • Women Are Wiser: She appears to be more intelligent and sensible than her son and late husband, as shown she scolded Nendou when her was playing with knives and when she took her credit card away from Nakanishi after he states hi plans to use it to purchase some expensive magic equipment.

Voiced by: Tomoaki Maeno (Japanese), Brandon McInnis (English)

Kokomi Teruhashi's older brother and a famous teenage actor and idol, who performs under the stage name "Toru Mugami". He hates Saiki and wants to keep him away from dating his sister (because his biggest dream is to marry her himself).


  • Big Brother Attraction: Inverted; he wants to marry his own younger sister.
  • Big Brother Instinct: He's extremely jealous over his little sister. But it turns out that it's more than fraternal love.
  • Bishōnen: Part of the reason he's a famous actor and idol, and he's the brother of Kokomi Terushashi, which helps.
  • Bitch in Sheep's Clothing: When nobody is around, Makoto will openly insult Saiki and ramble about his plan to marry Kokomi (who apparently doesn't know about any of this).
  • Brother–Sister Incest: It's somewhat implied that his feelings for his little sister are not platonic in his introduction. Come his second chapter, and the subtext becomes text.
  • Clark Kenting: Several times he appears wearing sunglasses. When they come off, he ends up getting swarmed by fangirls.
  • Crazy Jealous Guy: He's insanely jealous of Saiki because Kokomi likes him and will insult or berate him at the slightest provocation.
  • Dissonant Serenity: He keeps a calm, upbeat attitude while insulting Saiki and demanding he die.
  • Double Subversion: At the first it looks like Makoto is in love with Kokomi, but it turns out he's actually her brother. Then it's revealed that he's actually in love with her despite this fact.

  • Stepford Smiler: He keeps a serene, smiling expression most of the time.

  • There Are No Therapists: Lampshaded by Saiki, who's disturbed that someone like Makoto has gone unchecked for so long.
  • The Unsmile: His fake smile becomes an insane, deranged grin when he declares that he will marry Kokomi.

A lost hamster that ran away from its owner to explore the world, only to discover the world is a dangerous place. It decides to head back home, but finds its owner has bought a new hamster, so Saiki finds it a new owner. It ends up being adopted by Nendou, who names it after his own former pet hamster.


  • Gender Reveal: Reveals herself to Saiki be a female, despite everyone thinking she is male.
  • Tsundere: Towards Nendou, who actually takes very good care of it. Saiki even asks if it is one word for word.
