Chiyo Mihama (Chiyo-chan)
Voiced by: Ayaka Saitou (JP web short), Tomoko Kaneda (JP series), Jessica Boone (EN)
The youngest and cutest of the girls, she's a 10 year old child prodigy who transfers to Yukari's class and almost always get the highest scores. While she excels in her studies, she fares poorly at sports. To her friends amazement, she comes from a wealthy family, yet isn't spoiled because of it. Instead, her classmates think she turned out to be the perfect child (from a parent's perspective) as she's kind, responsible, and mature for her age.
- Adorably Precocious Child: Her classmates are often surprised by her maturity, despite her young age, and have even made her their class representative. But what they're most impressed by, is just how darn CUTE she is.
- Art Evolution: Inverted. In the manga, her pigtails start off looking realistic but later become the infamous football-shaped ones.
- Big Fancy House: She lives in one, although it's a Simple, yet Opulent one.
- Boyish Short Hair: In Osaka's fantasies, Chiyo-Chan has this whenever her pigtails are removed.
- Butt-Monkey: You'd think someone as cute, sweet, and innocent, as she is would have Karmic Protection, right? WRONG. Chiyo gets abused on a regular basis; with much of it coming from Tomo and Yukari.
- Cheerful Child: Her picture's literally the first thing you'd think of (and see) when you see that trope.
- Child Prodigy: She did well enough academically that she was skipped straight into her sophomore year of highscool, at 10 years old, and consistently scores the highest grades at the school. She even tutors some of her classmates, like Chihiro. Guess who ends up being valedictorian?
- Cloudcuckoolander's Minder: Plays this role for Osaka from time to time, usually in small, subtle ways (e.g. holding Osaka's shirt for fear that she may actually try to fly off of a roof).
- The Cutie:
- Chiyo's character in a nutshell. In the very first episode, and for much of the series, everyone fawns over her and gushes about how cute and adorable she is. This is especially the case for Sakaki, who often suffers from Cuteness Overload anytime she's near her.
- Her teachers can't resist either. One of them has all his students who failed to turn in their homework line up at the front of the class to give each of them a whack with his teacher's manual. When he gets to Chiyo, she was so vulnerably adorable that he hesitates before finally giving her a soft tap on the head.
- Add a Penguin Suit, and the adorable factor flies off the scale. Enough that, during their annual Culture Fest, it caused students from all over the school to swamp their Kitty Cafe with customers!
- Everything's Better with Penguins: Chiyo + Penguin Suit = Weapons-Grade Cute.
- Expressive Hair: Literally in Osaka's New Year's dream and not so literally in episode 10 where Chiyo tries her darnedest to reassure Osaka that they, Yomi, Tomo, and Sakaki will all be in the same class for their second year in high school.
- Fear of Thunder
- Girlish Pigtails: She wears her hair this way, though her pigtails look more like two footballs attached to her head than anything else (in the manga, her pigtails started out looking like actual hair before they gradually became more like solid shapes). Osaka sometimes wonders if they're detachable, or even alive...
- Grade Skipper: Despite being only 10 years old, she was smart enough to skip several grades and go straight to high school.
- Height Angst
- Heroic B.S.O.D.: Whenever she gets reminded of the time she rode in the car with Yukari driving.
- Human Mom Non Human Dad: Uhh...maybe...
- Image Song: FIVE of them.
- Implausible Hair Color: Was once the trope image. She is a red haired Japanese in a realistically-colored series.
- Improbable Age: She's a sophomore at only 10 years old.
- Innocent Prodigy: She has the best test scores in the school, but most teenage issues go way over her head.
- Just a Kid: Chiyo hates the fact that no one takes her seriously, wishing she was older and more intimidating like Sakaki. This in itself is hilarious considering the fact that Sakaki wants to be just like her.
- Kid-Appeal Character
- Lady And A Scholar: Bright for a young age, and a polite young girl to boot.
- Nice Girl: She's polite and very helpful in class, such as tutoring classmates who need it, and organizing events for their school's annual Culture Fest. Chiyo even invites them to her family's summer home twice, during summer break.
- Oh, Crap!: Examples include that time Yukari said the class trip was cancelled, and when Chiyo found out Iriomote cats can eat animals as large as her dog.
- Ojou: Chiyo lives in a large estate and her family is wealthy enough to afford a summer home on beachfront property. A fact which stuns Tomo and Yomi, when she first tells them about it.
- Pride: Not often presented, but Chiyo's biggest flaw is that she expects to be on top and treated as such. Most obviously shown when Tomo deliberately studied extra hard to best Chiyo on a written test. It didn't matter that it was in physical education, or that Chiyo was just barely behind Tomo; Chiyo was visibly angry that Tomo bested her. And when the two next got a test back (in a different subject) with the expected result, Chiyo glared at Tomo as if to gloat.
- The Protagonist: While not the main character, per se, she'll usually explain things to the viewer via monologue, or narration. She also has the most number of episodes dedicated to her, with Sakaki having the next highest number.
- Secretly Wealthy: Chiyo skipped some grades and attends High School despite being of grade school age. She's so excited about being a highschooler she decided to get a part-time job because highschoolers usually have that sort of job. Her employer hired her because he thinks she must be poor to be desperate enough to "forge" a high schooler card. Since he never told her what he thinks, she's oblivious to the misunderstanding. She's actually wealthy. When her friends come visit her house, they're shocked at how much land (something of a premium in Japan) one that her family owns.
- Spoiled Sweet: As seen in the Nice Girl entry.
- Supreme Chef: Even cooks her own lunches before school. They're all very complex and very tasty looking.
- Tareme Eyes
- Token Mini-Moe: For the third time, she's the trope image here as well.
- Why Did It Have to Be Snakes?: Poor Chiyo had the misfortune of having to ride with Yukari, during their first trip to her summer home. It's left her scarred, possibly for life.
- Wise Beyond Her Years: Not just in the sense of having the highest grades at the school, but some of her narration is pretty insightful for someone her age.

The tall, quiet girl who sits in the back of the class. Most students are intimidated by her height (174cm and still growing) and her appearance, but she's actually kind and too shy to make friends. Sakaki suffers extreme Cuteness Proximity and often daydreams about cute things, like kittens, or Chiyo. Sadly, her mother is allergic to cats. Sakaki is also an excellent student and an exceptional athlete. She often wins her sports festival events through natural talent rather than training. Needless to say, this seems unfair to Kagura.
- Academic Athlete: The best athlete at the school, and also excels in her studies.
- Aloof Dark-Haired Girl: Subverted. She's tall, dark-haired and imposing, but her apparent aloofness is really because she's a Shrinking Violet, in spite of her physical appearance.
- Animal Motifs: Cats. Her goal throughout the series is to have a cat that loves her instead of biting or scratching her, and she ultimately adopts a baby Iriomote cat.
- Animals Hate Her: In episode 22, she looks at her scarred hand and comments that she "might not get off so lightly" if she encounters an Iriomote cat, instead of the more domestic variety. Mr. Tadakichi and Mayaa like her though.
- Attractiveness Isolation: Other students are scared to talk to her either because they think she's too awesome or because she's intimidating. She winds up often wishing she'd get invited into club activities, since she's too timid to reach out for them herself.
- Beyond the Impossible: Until Mayaa, whenever Sakaki tries to pet a cat, the best result possible is for the cat to run away (as opposed to biting her). Then she tries to touch a robot cat doll. It fizzles and stops working, smoke coming out of it, before she can reach it.
- Big Brother Instinct: Be it from snowballs, or kids who make fun of her during sporting events, or a mob of anrgy cats - Sakaki will always be there for Chiyo.
- Blue with Shock: She gets this either when she is thinking of something that's impossibly cute, or when any of her friends actions horrifies her. Like the time Osaka said Mayaa would be nice 'n boney, one day. Or when Yomi heard she liked bears and presented her with a can of bear stew as a souvenir!
- Broken Ace: Talented in both academics and athletics, tall and well-endowed, to the point where she is even the object of attraction and admiration of many a girl. Underneath it all though, is the resentment of her image and related insecurities, where she would much prefer to be adorably petite, not to mention that she shows more interest in animals and all things cute, something lost on almost everyone else. It certainly doesn't help that her looks scare off as many people in that she appears to be a delinquent, when deep inside she would like to be friends with them.
- Butt-Monkey: Life seems to love denying her the things she wants, whilst dangling them in front of her. Like how Chiyo gets to be cute and adorable, and can openly enjoy things like stickers and plushies, while Sakaki can't because everybody expects her to be cool and grown up because of her appearance.
- Character Development: She appears to open up more and more to her friends as the series progresses, mostly to Chiyo and Kagura.
- Cloudcuckoolander: Not on an Osaka level, but between her shyness and her strange daydreams, when Sakaki does say things they can be rather...odd. Chiyo-Dad, below? She's the one who sees him most often, and she seems to be thoroughly convinced that he really is Chiyo's father.
- The Comically Serious: She'll say some of the most bizarre things with a perfectly straight face and monotone... and mean it.
- Cool Big Sis: Chiyo starts to look up to her as one, once they become friends.
- Covert Pervert:
- When Tomo puts Yukari and Minamo on the spot about their love lives, Sakaki quickly re-enters the room and can be seen peeking from behind Yomi and Tomo, while trying to listen in. Then she inches forward to make sure she didn't miss anything (seen from 14:40-15:59 here).
- It gets hilariously subverted two scenes later, as she ends up hearing more than she would have liked and couldn't look Minamo in the eye the following morning. Though Yomi and the others were very appreciative.
- Curtains Match the Window - Black Hair. Dark Eyes.
- Cuteness Overload: Very, very prone to this, usually around cats and whenever she misinterprets something Chiyo says, which causes her to imagine Chiyo doing incredibly cute things.
- Daydream Believer: Really believes that Chiyo's father is a yellow cat because of her dreams.
- D-Cup Distress: Sakaki dislikes the amount of attention that's drawn to her breast size. Life's tough when your less endowed friends always talk about 'em.
- Death Glare:
- This is her default look early in the manga, much to the fright of Chiyo and the others. She means no harm though.
- Sakaki's intimidating appearance is clearer in the manga, where in her first scene with Chiyo she's drawn with a hostile-looking expression, making it clear why Chiyo would be quite afraid of her. She's drawn with a softer expression in the anime. This may prompt anime viewers to wonder what Chiyo is so afraid of. However, both the anime and manga mention Sakaki's bandages from Kamineko's bite being mistaken for an injury from a fight, so you can see where the other students get their impression of the character.
- Deuteragonist: Has the second most spotlight episodes, undergoes the most development, and many characters are defined by their interactions with her.
- Even the Girls Want Her: ...and not just Kaorin. In the 4th episode, one of Kaorin's friends says Sakaki is better than any of the boys at their school. A later episode shows her being followed by a group of girls, who gush about how cool and awesome she is, with little hearts over their heads. Then finally squee and have to hug themselves. Yeah.
- Face of a Thug: Sakaki looks like an Aloof Dark-Haired Girl, so everyone assumes she's a juvenile delinquent. In reality, she's a Shrinking Violet who loves everything cute and cuddly.
- Fear of Thunder: Earthquakes, mechanical guards at construction sites, and horseflies too.
- Flash Step: Goes hand in hand with her propensity for cute animals. When told that Chiyo is going to go visit Mr. Tadakichi, and asked if she would like to come along, Sakaki is waiting downstairs, outside, before the question is finished.
- Fragile Speedster: She's unmatched at pure speed, consistently dusting the competition during their school's annual Sports Fest, and also has fast enough reflextes to Catch and Return a thrown snowball. Her greatest weakness (as she tells Chiyo when she places 6th in a 5k run) is endurance, and she also goes doubles over in pain from a headbutt from Kamineko.
- Friend to All Living Things: Heartbreakingly subverted, as most of them would rather have her for a snack than be her friend.
- Gag Boobs: Her chest is the root of many jokes in both the anime and manga; usually to her chagrin.
- Gainaxing: Invoked whenever she's warming up, or anytime during a race.
- Gentle Giant: Enough that you'll want to give her a hug.
- Girls Love Stuffed Animals: The few times we see her room, she's shown to have stuffed animals and plushies on her bed, her couch, and her bookshelf.
- Height Angst
- Huge Schoolgirl: 174cm tall. The punch line of one strip is that if anybody gets lost in a crowd, to meet next to Sakaki because she's so huge she'll be easy to spot anyway.
- Image Song: Kokoro wa Shoujo de PARACHUTE and Mahou Neko ni aeru Hi wa. The second one features Chiyo.
- Internalized Categorism: Sakaki hates the fact that she's tall, popular, has big boobs, and is great at sports...and wishes she were short and cute like Chiyo.
- Japanese Delinquents: Her natural appearance and reticence leads the other girls to mistake her for one. Later, it's deliberately invoked during the second annual Sports Fest, when Yukari gives her a gakurannote to wear; causing Kaorin to fangasm.
- Also, she often comes to school with numerous cuts and scratches, which most people assume she got from a fight. Actually, they're from her attempts to pet stray cats.
- Kind Hearted Cat Lover: Insanely kind-hearted. Loves cats something fierce. Even if they don't love her back.
- Kindly Vet: Will likely be this once she graduates from college.
- Laser-Guided Karma: In the form of Mayaa.
- Let's Get Dangerous!: In a way. Everyone knows she's good at sports. Old news. Tease Chiyo because she can't run? She takes that personally and will proceed to demolish the competition in response. Also acts as an awesome bodyguard for Chiyo during the snowball fight.
- Luminescent Blush: Quite often, mostly in response to seeing kitty cats, or while imagining cute things.
- Martial Arts Headband: Subverted in the last sports festival episode. She starts off wearing it as normal around her head then, after hearing a boy from another class make fun of Chiyo's running, she takes it off and uses it to tie her hair in a ponytail.
- Misunderstood Loner with a Heart of Gold: Because of her looks, people tend to avoid her when Sakaki is actually a Shrinking Violet who would like to have more friends.
- Nice Girl: Despite her intimidating size, she's doesn't have a mean bone in her body.
- Oblivious to Love: Notices Kaorin's strange behavior around her, but doesn't seem to know the reason for it.
- Odd Couple:
- With Kagura, although it does not stand out as much as Yomi's and Tomo's friendship.
- In the Manga, she'll also often form one with Osaka. The two have some very interesting conversations.
- Only One Name: It's unknown whether it's her first name, or her family name.
- Pet Baby Wild Animal: Mayaa.
- The Quiet One: She usually doesn't talk much due to her shyness. This is usually misunderstood as aloofness.
- Rapunzel Hair: Her hair length can range from a little past her waist to almost to her knees.
- Screams Like a Little Girl: In case it wasn't clear, she let out the shriek that notified the whole class of the cockroach that was scuttling around the room in episode 2.
- Shoo the Dog: Sakaki must do this to Mayaa before leaving Okinawa. He comes back to drive off Kamineko from the streets.
- Shrinking Violet: Sakaki is painfully shy and withdrawn, for much of the series, but gradually opens up thanks to Chiyo and Kagura.
- Squee!: Whenever cats or anything cute are involved. Especially when it comes to Mayaa.
- Statuesque Stunner: A rare case of also being a Huge Schoolgirl.
- Stealth Hi/Bye: When cute things are involved, she'll be out of the school before you can finish your sentences.
- The Stoic: Not by choice. Sakaki certainly has plenty of emotion, but she is not very emotive, having difficulty communicating her feelings to other people. As a result others tend to jump to inaccurate conclusions about what she is thinking or feeling, assuming her aloofness is by choice when she would rather open up.
- Sugar-and-Ice Personality: So, so very compassionate and cute on the inside, but outside, she looks like a cold, tough Huge Schoolgirl. Unlike most examples, her coldness isn't a façade she's putting up to fool everyone, but something she does completely by accident.
- Throw the Dog a Bone:
- Tadakichi-san is the first animal she was able to successfully pet. For several hours.
- Near the end of te series, Sakaki finds Mayaa, the first cat to ever let her pet him and later goes to find her to have her adopt him.
- Tomboy and Girly Girl: She's the girly one, to Kagura's tomboy.
- Tomboy with a Girly Streak: An in-universe example. She's believed to be a delinquent, due to frequently showing up with her hands or face bandaged, creating the impression she often gets into fights. Plus, she's the best athlete at the school. So Chiyo and Kagura are surprised when they eventually learn that Sakaki's actually shy and quite feminine; preferring cute things over being cool.
- Tsurime Eyes
- Why Did It Have to Be Snakes?: She's afraid of earthquakes, thunder, horseflies and mechanical guards at construction sites.

The most energetic member of Yukari's class who likes to make everything into a competition. Failing that, her default behavior is to annoy others, or cause a commotion, in the name of fun. Problem is, her idea of "fun" isn't always the same as everyone else's. She's best friends with Yomi, though it's a wonder to their other friends how, or why, it ever happened.
- A-Cup Angst: While she doesn't obsess over it, she wants bigger boobs and gets excited when they have their yearly measurements taken. She also makes perverted jokes (moreso in the manga), usually about Sakaki's, Kagura's, and Yomi's breasts. Which suggests that she may be envious.
- Alliterative Name
- And Call Him "George"!: Tomo gets too rough while playing with Mayaa and gets scratched as a result.
- Berserker Tears: When Yomi manages to eat curry noodles without splattering it all over herself, Tomo is pushed over the top and goes on a rampage in the lunchroom with tears in her eyes until she accidentally hits Yukari. Yukari's subsequent reaction must be seen to be believed.
- Big Bra to Fill: Discussed in regards to her desire to be like Fujiko Mine. Tomo believes the only thing lacking is her chest size...
- Book Dumb: ...and proud of it! Unless it will annoy someone like when she studied for a test to outscore Chiyo just to spite her.
- Brilliant, but Lazy: Normally low-scoring and rarely saying anything intelligent, when she applies herself she can pass exams — and even maxed out her mark in a health exam when she specifically studied for it. She seems to pick and choose what she studies for. Tomo also seems to act bone-headed as much as being stupid.
- Chaotic Stupid: She's definitely chaotic. The stupid part is questionable, since she isn't dumb when she actually applies herself to her studies. She will, however, do stupid things just to see what would happen
- Competition Freak: Over any and EVERY-thing. From breast sizes, comparing failing test scores with Kagura and Osaka, or making bread runs during lunch. She even showed up late for class, just so she could stand in the hall to try to set a record for holding out the longest!
- Cosplay: As a giraffe, much to the annoyance of Yomi, Yukari, and Minamo. Hoo boy, especially Minamo..
- Eskimos Aren't Real: Tomo believed reindeer were fictional, until Chiyo and Sakaki explained they were real.
- Expository Hairstyle Change: Every school year.
- Fangirl: Of Fujiko Mine and is growing her hair to imitate her look. She eventually drops the idea and cuts her hair short, at the start of their senior year.
- The Friend Nobody Likes: Tomo is a colossal pain in the ass. Enough that Kagura and the others wonder why Yomi ever wound up being best friends with her.
- The Gadfly: Kagura even asks: "Why do you put so much energy into pissing people off?". See It Amused Me.
- Generation Xerox: She's a Yukari Jr down to her Jerk Ass tendencies and lack of any skills.
- Genki Girl: The current page image.
- Giver of Lame Names: She dubbed Ayumu "Osaka" because she came from Osaka. In the manga, it is revealed that she gives pets equally generic names.
- Gratuitous English: Like Yukari, inconsistently dubbed into Gratuitous Spanish.
- Image Song: Sora wa Tobikiri Paradaisu and Poi Poi Peace. Also shares one with Yomi, and another with Kagura and Osaka.
- Insult Backfire: When Yukari smirks and points out Tomo won't get very far from copying Chiyo's homework all the time, Tomo calmly answers that she copies Yomi's too.
- It Amused Me: This is her primary motivation - from studying for a test long enough to get into their school just to spite Yomi, to repeatedly tormenting Chiyo, to causing a ruckus and "unintentionally" smacking her classmates while trying to kill a cockroach - she does it all for shits 'n giggles.
- Jerk With A Heartof Gold: Picture Yukari as a teenager. That said, she's not really malicious, she's just hyperactive and likes to mess with people because it's funny. She does care about her friends at the end of the day - for instance, in the finale of the anime, she leads the assembly in applauding Chiyo when she is made Valedictorian.
- Laser-Guided Karma: Mayaa successfully puts Tomo in her place for her behavior, by scratching her when she bothers him too much.
- Like Parent, Like Child: According to Yomi, Tomo's dad acts exactly like his daughter, and even has the same haircut.
- Ms. Vice Girl: Not only is she willing to cheat on tests, or eat lunch during class, she'll try to entice her friends and classmates to get in on it to (with varying degrees of success). And during their senior year of school, she tricked Chiyo into inviting them back to her summer home under the pretense of wanting it to be a study trip.Tomo: (shamelessly) "I lied."Chiyo: (in shock) "Wha..?? SO BLUNTLY?!"
- Not So Different: Her and Yukari.
- Odd Friendship: With Yomi.
- Power Copying: An Imagine Spot shows the viewers what might happen if Tomo copied Sakaki's athleticism, Chiyo's book smarts and Osaka's strangeness.
- The Rival: She tries to antagonize and compete with everyone, just for the hell of it. Chiyo, Sakaki, and Kagura are her usual rivals. She was also Osaka's Unknown Rival on Osaka's first day.
- Screwy Squirrel: As seen in the Friend Nobody Likes and It Amused Me examples, Tomo gets a kick out of screwing with her friends, just to get a rise out of them; especially Chiyo and Yomi.
- One of her cruelest, is when she volunteers to see if Yomi had passed her college entrance exam by looking for her name on the results board. Despite looking right at it, she tells Yomi it wasn't there, causing her to panic and start to cry, until Osaka checks and tells Yomi her name is there. Tomo then had the gall to congratulate her, along with the others. Yomi was not amused.
- Small Name, Big Ego: She doesn't excel at anything, because she never really applies herself to anything, but still likes to compete with her classmates, and seems to think she's pretty hot stuff. She isn't.
- Standing in the Hall: Self-inflicted.
- Tareme Eyes
- Tempting Fate: Any time she chooses to hammer either of Yomi's berserk buttons (see the related entry in Yomi's section), she's pretty much asking for it.
- Too Dumb to Fool: Osaka comes to realize this, when she tries to prevent the "Osaka" nickname from spreading. She explains that she'd been in different suburbs and only lived there briefly as a reason not to call her that. A native of Japan would recognize those locales were suburbs of Osaka. But all it did was confuse Tomo, so she stuck with the simplest one, since it was the only one she could remember.
- Too Kinky to Torture: In regards to Yukari's driving.
- Unsympathetic Comedy Protagonist
- Vitriolic Best Buds: With Yomi.
- Weight Woe: Although she constantly teases Yomi about her figure, Tomo at least once lamented her own, claiming that whilst calories go to Sakaki's height and chest, hers go straight to her stomach. Perhaps she pesters Yomi about it out of insecurity.
- With Friends Like These...: She's not really malicious, though, she just annoys people because it's funny.
Koyomi ("Yomi") Mizuhara
Voiced by: Satsuki Yukino (JP web short), Rie Tanaka (JP series), Nancy Novotny (EN)
The most normal member of Yukari's class, and also the most focused. She's best friends with Tomo and has an amazingly high-tolerance level for her shenanigans (at least, until her tolerance reaches its limit). In most cases, she plays the Straight Man, though she can be just as juvenile as her friends, depending on the circumstances. Yomi also enjoys eating and, as a result, is always trying to diet.
- Academic Athlete: An honors student, second only to Chiyo academically. She's also an outstanding athlete and usually does well during their school's annual sports fest.
- Badass Bookworm: Tomo can attest to this better than anybody, given the number of times she's been "double chopped" and Shoryuken'd by her.
- Berserk Button: Don't call her stupid, and never, ever, call her fat.
- Bitch in Sheep's Clothing: Has her moments. She's the Only Sane Man most of the time, but she does have a pretty mean sense of humour, like infamously feeding Osaka a super-spicy croquette and giving Sakaki a can of bear soup. She can also be pretty mean to Tomo, even when the latter has not provoked her.
- Brainy Brunette: She'd likely be the smartest student at the school, were it not for Chiyo.
- Cloud Cuckoolanders Minder: Tomo may not be the extreme Cloudcuckoolander that Osaka is, but she's enough of one that she still occasionally needs Yomi to fill this role for her. Though Yomi's just as likely to sit back and let karma run its course as she is to intervene.
- The Comically Serious: Tends to keep her chill and focus even among her sillier and more eccentric classmates, such as Tomo and Osaka, respectively, though she does have her moments when she behaves a bit more like them.
- Cross-Popping Veins: Quite often, due to Tomo's antics.
- Deadpan Snarker: She may put up with Tomo's antics, but she won't hesitate to take digs at her. Yomi occasionally snarks on Osaka as well.
- Dreadful Musician: Considering her Seiyuu's musical skills, this is very ironic by itself.
- Girlish Pigtails: In the supplementary lessons.
- Hollywood Tone-Deaf: Yeah, right...like Rie Tanaka can really sing that badly.
- Image Song: Sorezore no Oneway and Oishii Kimi-Tachi.
- Jack-of-All-Stats: She's athletic, but not to the same extent as either Sakaki or Kagura. She's undeniably strong, but Kagura has her beat in that department. And, though she's an honors student, Chiyo consistently scores the highest marks at the school.
- This is even reflected in her bust size and her figure. Yomi's definitely got nothing to complain about, but Sakaki is the one the girls swoon over. Tomo mocks her for her JOAS status in the Tsukurimashou image song.
- This may also be the reason why Osaka calls her "Hawaiian" instead of "American" like Sakaki and "Japanese" like Tomo, as Hawai'i approximately lies between mainline North America & Japan.
- Even her full name references this, as it roughly means to "read between the lines", as in, the middle of them.
- Jerk with a Heart of Gold: She does care about her friends despite her mean sense of humor.
- Meganekko: As seen in the image above.
- Nerds Are Sexy: She's second only to Sakaki, in terms of her looks and figure. Which is why it's baffling to Tomo (and the audience) that she seems to think she's overweight.
- "No. Just... No" Reaction: Her usual reaction to Tomo's antics is to stare either blankly, or incredulously, for a moment, then simply get up and walk away for the sake of her own sanity.
- Not So Above It All:
- Yomi can be just as bad as the others, depending on the circumstances. Like when she trolled Osaka by getting her to try one of her croquettes, after Osaka said she couldn't eat anything spicy. And she was just as engrossed in Minamo's "talk" as Tomo and the others were.
- There was also the time she said getting excited about a trip to the Magical Land amusement park was childish, yet bought the brochure the moment they were gone and spent all evening planning which rides she wanted to go on. She wound up missing the trip because she'd caught a cold from staying out so late, with the chill in the air.
- Not So Different: To Minamo.
- Odd Friendship: With Tomo.
- Only Sane Woman: A role she shares with Chiyo, and Minamo whenever she's around.
- Ordinary High-School Student: She's the most normal one of the bunch, which is why she's usually The Straight Man.
- Out-of-Character Moment: Tricking Osaka into eating food doused in cayenne is a surprisingly Tomo-esque thing for Yomi to do.
- Rapunzel Hair: In the anime version, where her hair is almost as long as Sakaki's.
- Scary Shiny Glasses: Usually played straight, but also double as her equivalent of Blank White Eyes.
- Shoryuken: Tomo brings it on herself, by deliberately provoking her each time.
- Sick Episode: She misses out on the girls' trip to Magical Land because of a fever. She gets another one after playing in the snow by the end of the same episode. Poor Yomi...
- Smart People Wear Glasses: One of the smartest students among the main cast (but second only to Chiyo), and has the specs to match.
- The Social Expert: Inverted. She just tolerates her classmates.
- Straight Man: She almost has to be, since hardly anyone takes Chiyo seriously, Sakaki's usually daydreaming half the time, and they damn sure can't depend on Yukari!
- Trademark Favorite Food: Curry. Heck, anything spicy.
- Vitriolic Best Buds: With Tomo.
- Weight Woe: Though fans will wonder why, since there's nothing wrong with her figure. Yet, she's always trying some sort of diet.
- Why Did It Have to Be Snakes?: She's afraid of cicadas.
- Younger Than They Look: She looks like she's in her early 20's, but is really just a highschool student, which would put her around the 15-18 age range. Lampshaded by Tomo in the manga, who rants about being mistaken for a middle schooler and says that she wishes she could be mistaken for a "College Student or Secretary" like Yomi.
- Zettai Ryouiki: She qualifies as a Grade B in the series proper, and gets bumped to an A in the Supplemental Lessons chapters.
Ayumu ("Osaka") Kasuga

By far, the most unusual of Yukari's students and easily one of if not THE, most popular member of the cast. As her nickname suggests, she's a transfer student from Osaka, though she only lived there for a year. She's known for her non-sequiturs when speaking, and her habit of daydreaming. Osaka isn't the brightest crayon in the box and is so hapless, that even Chiyo can beat her at sports; but she has a knack for puns and riddles and can occasionally pick up on things the others miss.
- Accent Adaptation: In the English dub of the anime and English manga, Osaka is given a Southern accent in place of her Kansai Regional Accent in the original Japanese.
- The first run of the translated manga has Osaka suddenly start speaking with a thick New Yorker accent in a few strips before quickly dropping it.
- A-Cup Angst: When Yomi quips that Chiyo was only flat because of her age, and might become as well-endowed as Sakaki when she's older, Osaka and Tomo both call Chiyo a traitor. Mr. Kimura completely ignores Osaka because of this, which is ironic given she seems to be the only student who isn't freaked out by him.
- Adorkable: She's spacey, slow and just straight-up weird. It's all part of her unique charm.
- Ambiguous Disorder: She has an unusual way of thinking, compared to most people, and her behavior can seem a bit strange, at times, making it easy to assume she might have some sort of mental disability, with some people speculating she is on the autism spectrum. Despite this, she gets only slightly below average grades at a regular school and manages to socialize somewhat normally.
- Asleep in Class: She is constantly falling asleep in class, to the point that she is the trope picture
- Berserk Button: If you value your health, do not break chopsticks in a different manner to the way Osaka prefers.
- Bird Run: Subverted; Osaka tries this during a relay race since she thinks it can keep other runners from passing her, but it only slows her down. Then again, Osaka isn't a very good runner to start with; she even loses to Chiyo.
- Book Dumb: Largely due to her inattentiveness and her habit of falling asleep, during class,
- Breakout Character: The fans absolutely love her and consider her to be one of the main draws of the series for reasons covered in the other entries of her section.
- Butt-Monkey: Not that it bothers her. At least, not most of the time since she keeps her head in the clouds.
- Cloudcuckoolander: The Trope Codifier and trope picture for the Anime and Manga section. For. A. Reason.
- In Episode 13, a bird, possibly a cuckoo, actually lands on her head!
- Her Image Song, "Time Pavement", starts with the sound of a cuckoo clock going off, which continues for the rest of the song.
- The Cuckoolander Was Right: See the Suspiciously Specific Denial entry in Kaorin's section. Not that it came as any surprise to the readers.
- Does Not Like Spam: She doesn't like spicy foods. Yomi makes this work to her advantage.
- Dreadful Musician:
- The only time she's seen with an instrument, she handles it rather poorly. (It was because she had the hiccups at the time.)
- Averted in the Christmas Episode, where she sings at Karaoke and other girls find her singing nice.
- Engrish: "OH MY GAH!"
- The Fool
- Genius Ditz: At first, one might think Osaka is stupid, or simply slow to grasp things. But while the latter may be closer to the truth, she's surprisingly sharp when it comes to riddles. She also notices things her classmates miss. For example, she was the only one to note that none of them had boyfriends, and was the only one who noticed Kaorin's crush on Sakaki and thought to ask if she was gay.
- Hidden Depths: See Genius Ditz above. Also, she does understand topics related to sexuality.
- Hollywood Personality Disorders: She seems to have strong schizotypal traits, though likely falls short of and is a bit too young to have a personality disorder. She exhibits signs of unusual experiences (unusual thoughts and unusual perceptions), cognitive disorganization (tendency for thoughts to become derailed and to derail conversations), and impulsive nonconformity (somewhat poor impulse control and unstable mood). (All 3 traits are well-exemplified here.) The only trait she doesn't seem to really exhibit is introverted anhedonia (deficit of pleasure response in physical and social stimulation), and contrary to the stereotype of schizotypals she is actually quite extroverted (and extroversion doesn't exempt you from schizotypy). As noted in an article on schizophrenic autism (separate from the autism spectrum), which is also exhibited by people with high levels of schizotypal traits, the activity of people with such strong schizotypal traits tends to show itself through "friction with the situational context." I would say that Osaka produces quite a bit of "friction." Here's the article:  The article gives another example of that kind of friction: "A famous vignette of a schizoid father, who buys, as a Christmas present for his dying daughter, a coffin, illustrates this odd friction." Compare this to the friction Osaka produces.
- Derailment is related to knight's move thinking (also called lateral thinking), which is the kind of thinking that might enable Osaka to be so good at certain kinds of riddles (as seen in the Genius Ditz entry).
- The Idiot from Osaka: Subverted. At least Tomo is disappointed when she turns out not to fit the stereotype.
- Image Song: Shikkari! TRY La Lai, Time Pavement, and Hororin Confetti, which she shares with Chiyo.
- Kansai Regional Accent: Osaka mentions that she lived in Kobe when she was in elementary school and was born in Wakayama.
- Karakasa: When Osaka gets the idea of doing an obakeyashiki kisaten ("haunted cafe") for the School Festival, she imagines herself in a karakasa costume, struggling to serve tea while hopping on one leg.
- The Klutz: If you find yourself entering a three-legged race, find yourself another partner.
- Named by Democracy: Tomo gives her the name "Osaka" and the other girls outvote her before she can protest.
- Narrator All Along: Osaka's story about the girls being murdered on summer break.
- Nice Girl: Despite her spaciness, she's a kind and gentle girl.
- Nightmare Fuel Station Attendant: She is the trope picture for this, and we love her for it! However, most of the time it's unintentional on her part, despite what the fandom might tell you.
- Only Known by Their Nickname: Her name is Ayumu Kasuga, but everyone starts calling her "Osaka" by the start of Second Year. In the anime, she gets labeled as Osaka by the end of her first day in class, thanks to Tomo. Unfortunately, it sticks, as even the school addresses her by that name, when posting her test results. One moment in particular shows her looking at the class lists to see whose homeroom she was going to be in, by looking for "Ayumu Kasuga". She didn't see it, because her nickname had been posted instead.
- Petite Pride: Weakly claimed that "being Japanese is fine." Ten seconds later, she's yelling at Chiyo, because she might actually get boobs.
- Pungeon Master: Covered in the Genius Ditz entry.
- Serious Business: If she tells you to break your chopsticks correctly, you better break them correctly. Lampooned in this vid.
- Slasher Smile: One of the few hilarious examples of the trope, done while she's wielding a butcher knife!note
- Sleepy Head: She'll often nod off during class, or while she and her friends are having lunch on the school roof, or under a kotatsu, or... You get the idea.
- Tareme Eyes:
- Trademark Favorite Food: "Sataaa Andagiiii!"

A tanned girl who joins the main cast in the second yearnote . She's very athletically inclined and the only member of the group who isn't in the 'Go Home Club', since she spends much of her free time training for the swim team (which makes Minamo her coach). She becomes close friends with Sakaki, first out of a desire to compete with her, then after finding out what she's really like. Like Sakaki, her bust size is often the source of jokes, though she tends to be annoyed, rather than embarrassed by it.
- Adapted Out: When the hiccups chapter was adapted to the anime, it was placed much earlier in the series, meaning that Kagura was removed, and her role given to Tomo.
- Ambiguously Brown: Averted. Kagura contantly sports a tan, due to the amount of time she spends outdoors between swimming and jogging, and it deepens during the summer. Which is why she has tanlines in the shape of her school swimsuit.
- Big Eater: Kagura can really put the food away, thanks to the energy burned by her non-stop athletic activities. But she doesn't gain weight, to Yomi's disgust.
- Boisterous Bruiser: She's as loud and rowdy as Tomo but, unlike the latter, Kagura has a lot more steam to work with. Which she usually burns off with swim practice and jogging, after school.
- Boobs of Steel: She's very close to Sakaki on an athletic scale, and she's quite powerful.
- Book Dumb: A fact which bothers her to no end. She wants to do well in her studies, but she can't seem to grasp the material... even when she has help from Chiyo and Sakaki.
- Boyish Short Hair: Along with Hot-Blooded Sideburns.
- Catch-Phrase: "Moron!"
- Characterization Marches On: She used to be a quieter character in the earlier episodes.
- Chekhov's Gunman: She made several background appearances before becoming a main character.
- Declaration of Protection: In one of her crowning moments, Kagura tells Sakaki she'll keep cats in the area from biting her and shoos them away when they come after her. While Sakaki appreciated the thought, she tells Kagura she shouldn't run away from her problems.
- Dumb Jock
- Early-Bird Cameo:
- She's first seen in episode 6, when Yukari hears about the ringer Minamo has on her track team Kagura's shown doing warmups. She also appears in a few strips in the first volume of the Manga as a bit character before finally debuting into the cast proper.
- Kagura actually first appears in episode 4 jumping into the school swimming pool, but was nameless until episode 6.
- Gentle Giant: On her good days.
- Gratuitous English: Invoked when she runs into a foreigner at an airport and tries to help him with his luggage. But since she does poorly in English class, Hilarity Ensues.
- Hot-Blooded Sideburns
- Image Song: 'Ashita wa Makenai! Go! Friend!' where she sings about Sakaki, and 'Lazy Crazy Bonkuraazu', where she leads Tomo and Osaka.
- Indifferent Beauty: She feels this way in regard to her breasts. To her, they're just there. Which is why it annoys her whenever Tomo draws attention to her chest.
- Jerk with a Heart of Gold: She can be an occasional Jerkass, but it's never intentional. When she knocks down the tent Yomi and Chiyo were putting up for the third Sports Fest, she feels so bad about it that she actually starts to cry and said she'd do it herself to make up for it. Chiyo and Yomi forgive her and they put the tent up together.
- Lovable Jock
- Magic Skirt: Subeverted, since Kagura uses her hands to keep her skirt from flipping up, during the intro.
- Ms. Fanservice: A mild example, since she only does it twice. When Osaka asks about her tan, Kagura pulls back her shirt collar, allowing Osaka to see how far her tanlines go (though her back is turned so the viewer can't see what Osaka's seeing).
- Odd Couple: With Sakaki.
- Only One Name: Much like Sakaki.
- Only Sane Man: She's much like a lowgrade Yukari and Tomo mixed with Yomi's sassiness and assertiveness, and After Yomi the most normal and well adjusted of the girls.
- Passionate Sports Girl: She's a strong all-around athlete, second only to Sakaki in talent. In one of the later episodes, Chiyo and the others see her practicing out on the track, after school. Kagura also mentions wanting to try out for the All Japan Women's swim team.
- Sixth Ranger: She joins the group in Second Year.
- Tan Lines: Covered in the Ambiguously Brown and Ms. Fanservice entries.
- Tender Tears: Happens three times. The first was due to losing to Sakaki in the track race of the first Sports Fest, the second during the incident at the third Sports Fest (see the Jerk with a Heart of Gold entry), and the last one happens once they've graduated and are about to leave school, because she'd miss her friends and her teachers.
- Tomboy: A pretty straightforward example, from her appearance, attitude, and mannerisms.
- Tomboy and Girly Girl: She's the to tomboy, to Sakaki's girly-girl.
- Tsurime Eyes
- Unknown Rival: Initially to Sakaki. Immediately becomes a regular rival to Tomo, due to constant arguing and the fact that they're both addicted to competition.

The girls' homeroom teacher and their English teacher but, unfortunately, she isn't the most responsible sort. Yukari is often late for work for various reasons, like oversleeping, and has been known to cancel class to have P.E. instead. She's also fiercely competitive with her long-time friend, Minamo Kurosawa, due to her popularity with her students. Despite all this, Yukari still takes herself and her job seriously and takes offense whenever she thinks anyone's making light of her profession. Basically, she's like the crazy aunt — she even drives like it.
- Apathetic Teacher: She gets bored with her job easily. The show's opening even shows her sleeping at her desk. You know she's that apathetic when she comes back from summer vacation and one of her own students has to convince her to get motivated.
- Big Bad: Not Yukari herself, but her car is damn near close, seeing as how it managed to scar Chiyo for life.
- Blah Blah Blah: Yukari tries speaking to a foreigner in English, which the viewer isn't supposed to understand anyway. In the English dub, this turns into French.
- But Now I Must Go: She invokes this, near the end of the final episode after a few parting words with her students.
- Can't Hold Her Liquor: To say she's such a heavy drinker.
- Christmas Cake: And don't think it doesn't bother her. She once gave her class a pop quiz just because one of her friends got married. The next day, however, she seemed smug that her friend had apparently "rushed into things".
- Chucking Chalk: Once manages a double shot upside Osaka and Kagura's heads.
- Conspicuous Consumption: To the point where she'll aggressively attack anyone fortunate enough to have experienced anything of interest, before her.
- Drives Like Crazy: Yukari is, hands down, the queen of crazy driving. The "Yukarimobile" is a force to be reckoned with, and far more beat up than any less-than-seven-years-old car has the right to be. Her still being the Trope picture, even after it's been changed, should say something. On the plus side, riders of the Yukarimobile report no longer being scared of roller coasters (probably because at least roller coasters, though designed to thrill and frighten, are also designed to be safe).
- Dual Wielding: With a pair of lunch trays, when she beat the hell out of Tomo for making the mistake of hitting her.
- Envy: Quite a few of her Berserk Buttons usually relate to someone having or experiencing something she hasn't, such as Minamo getting birthday presents from her students or finding out that someone has eaten expensive foods.
- Evil Laugh
- First-Name Basis: The only teacher addressed by the students as such. note Some students go the extra mile and call her Yukari-Chan.
- Gamer Chick: She once arrives late to class because she got stuck waiting in line for the Limited Special Collector's Ultimate Edition of a game.
- Genius Ditz: However Yukari acts, she is still very much an English teacher and, thus, much more than capable in that language.
- Gratuitous English: Inconsistently Dubbed into Gratuitous Spanish. Justified slightly, because she is an English teacher.
- Hair-Trigger Temper: It doesn't take much to make her angry. She spends about half her screentime being pissed off about something or other.
- Hard-Drinking Party Girl
- Hero Stole My Bike: Yukari in the premiere, while Tod is trying to fix hers.
- Heterosexual Life-Partners: With Nyamo. Maybe...
- Hidden Heart of Gold: Seen when she tries to cheer up Osaka, by letting her know she'd still be in her homeroom class for her senior year. And in the finale, where she shares a few parting words to Kagura and her class.
- Hypocritical Humor: Frequently mocks Nyamo's Christmas Cake status despite being one herself.
- Image Song: Otona wo Yasunde Dekakeyou and Tenshoku Equal Kaikan no Housoku, both of which are shared with Nyamo, with the latter also featuring Kimura.
- Jerk with a Heart of Gold: Picture Tomo as an adult. Though she's not incapable of being a good person.
- Keep It Foreign: In the English dub, Yukari changes from being an English teacher to a foreign language and grammar teacher. It's similar for the first issue of the translated manga; the second issue got a new localization team and switched to her being an English teacher, though some other English-language gags are inexplicably changed to French and German.
- Late for School: All the time.
- Maximum Fun Chamber: Yukari's car.
- Ms. Vice Girl: Hoo boy, let's see here:
- When she found out Minamo had a star athlete on her track team, she decided to nose around and find out who it was. Then she tried to slip her a sweet bun (possibly laced with... something). Though we'll never know, since Minamo caught her in the act.
- The following year, Yukari pulled strings to get Kagura in her class, effectively stealing Minamo's star athlete to stack the odds in her favor for the next Sports Fest, since she now had Kagura and Sakaki on her team.
- On one, of several, occasions she decided to teach PE, she split her class into teams and sided with Tomo and Yomi, vs Osaka, Kaorin, and Chiyo, two of whom she knew sucked at sports and had no chance against a teacher. Until Minamo evened the odds, by switiching in for Chiyo.
- And she frequently makes bets with Minamo, and makes promises to her students - like saying she'd buy them juice if they won the next Sports Fest - but finds ways to reneg each time it's time for her to pay up. Even if it means hightailing it!
- Noodle Incident: She's managed to buy Minamo's silence about her highschool days, with a mere mention of a love letter she once wrote.
- Not a Morning Person: Between drinking and laziness, in general. It's one of the main reasons she's usually late for work.
- Not So Different: From Tomo.
- Odd Friendship: With Minamo.
- One of the Kids
- Rapunzel Hair: Only in The Movie, where her hair went from waist length to freaking enormous.
- Red Eyes, Take Warning: Tomo tries to smack Yomi in the face with a dinner tray, complete with a slow-motion jumping attack, but misses, and whacks Yukari in the face. Cue scary music and a slow-motion reveal of Yukari's glowing red eyes, then cutting to her whapping the living hell out of Tomo with two trays.
- Sadist Teacher: She frequently abuses her students for such things as "going on vacation with his parents" or being shorter than the rest of the students.
- Sensei-chan: Quite possibly the Trope Codifier.
- Tareme Eyes
- Tomboy and Girly Girl: She and Nyamo are the adult versions of this trope.
- Vitriolic Best Buds: With Nyamo.
- Wacky Homeroom
- Woman Child: This is often lampshaded by her students, and her fellow teacher, Minamo. Yukari has been known to ditch her own class on a whim, to go swimming, or goof off playing sports, depending on her mood. And, one occasion, was late for work because she'd been stuck in line to buy a PlayStation game.
- Would Hurt a Child: Poor Chiyo...
Minamo ("Nyamo") Kurosawa
Voiced by: Akiko Hiramatsu (JP web short), Aya Hisakawa (JP series), Monica Rial (EN)
The school's phys-ed teacher and swim team coach. A very diligent and caring teacher (especially in contrast to Yukari), and many students look up to her. She's been friends with Yukari since at least college (high school in the manga). Given Yukari's personality, one wonders how they stayed friends so long.
- Berserk Button: Don't mock her about being single and unmarried.
- Beware the Nice Ones: As cute and kind as she is, she can get scary when she's pissed off in the manga. This is best seen here.
- Book Dumb: Though not quite as bad as Tomo, Osaka or Kagura, it's still implied (see Corner of Woe below).
- Christmas Cake: Much to her dismay.
- Corner of Woe: During the third beach episode, she is unable to help the students with studying and is even shown up by Yukari.
- Early-Bird Cameo: Appears in the second episode of the anime, unnamed, before being formally introduced in the next episode.
- Heroic B.S.O.D.: Nyamo has a massive one the morning after she got totally drunk and gave some extracurricular education to the girls, and again when Yukari one-ups her with her mad Gratuitous English skills.
- Heterosexual Life-Partners: With Yukari. Fanon seems to think otherwise.
- Image Song: Otona wo Yasunde Dekakeyou and Tenshoku Equal Kaikan no Housoku, both of which are shared with Yukari, with the latter also featuring Kimura.
- In Vino Veritas: During the second beach episode, she drinks all the alcohol to avoid the disaster if Yukari gets drunk instead. She winds up giving the girls The Talk and then some.
- Nice Girl
- Noodle Incident: See previous entry and her Jerkass friend Yukari. Also, in one episode she has too much to drink and gathers the girls to impart some "serious-business" wisdom. Music drowns out anything she says, but the epic imagery, soundtrack, and the girl's rapt attention (plus her being drunk) suggests to the viewer she is telling them something inappropriate but awesome.
- Not So Different: To Yomi.
- Odd Friendship: With Yukari.
- Only Known by Their Nickname
- Passionate Sports Girl: The adult version of this trope.
- Reasonable Authority Figure: The only one the show has.
- The Straight Man
- Tareme Eyes
- Tomboy and Girly Girl: She and Yukari are the adult versions of this trope.
- Vitriolic Best Buds: With Yukari.
- You Gotta Have Blue Hair: Much like Sakaki. Not particularly noticeable, but still blue hair.

The series' lone male teacher—indeed, the only named male character period if Chiyo's Dad and Maya aren't counted, who's known for his perpetual open-mouthed stare and his fixation with highschool girls - especially Kaorin. As such, he's the most bizarre of the girls instructors. Despite this, he's Happily Married to a beautiful, loving waifu, with whom he has a daughter.
- Abhorrent Admirer: To Kaorin.
- All Men Are Perverts: The male students are "deeply moved" by his open acknowledgement of his motivation for becoming a teacher.
- Audience Surrogate: A case could be made for him being this. As a teacher who only got the job because he "like high school girls", he represents the adult Periphery Demographic who read the series solely for the Fanservice rather than the plot.
- Cloudcuckoolander: From designing cosplay costumes, to unintentionally scaring the crap outta the girls with his sudden appearances and oddball behavior, Kimura is just. Plain. Weird.
- Dirty Old Man: Kimura became a teacher because he likes high school girls but, unlike most examples, he seems content with staring at them. Or, he'll make lewd, albeit odd, requests. Such as complaining about the swim team not tending their noodle stall in their swimsuits, or asking for a glass of water from the pool where the girls swim.
- Early-Bird Cameo: Makes a brief voiceless appearance in the anime's first episode, a good 3 episodes before he's properly introduced later on.
- When Tomo asks why he became a teacher, he blatantly admits that this is the reason. Kimura will take opportunities to stare where he can get them, going so far as to ditch his own class (much like Yukari), to sit in on Minamo's swim class.
- "High school is high school." In other words, Kimura's joshikosei garb fetish ignores any and all age restrictions. In the manga, there's a point where the teachers wear high school uniforms for a costume race and Kimura hands Yukari a love letter ("Senpai, read this.")
- Evil Laugh: Done while dancing with Kaorin at the conclusion of the second Sports Fest.
- Fetish: For high-school uniforms, apparently.
- Gratuitous English: Mai waifu.
- Happily Married: His wife loves him unconditionally and finds him quite handsome. No, really. To be fair, as noted above Kimura really is a Nice Guy for all his perversion. He apparently donates to charity frequently, and is shown using his New Year's wish on world peace (with a 10,000-yen note).
- Hot for Student: Just about any one of the girls will do, but he's especially taken with Kaorin. However, Osaka is shown to be the only one he has no interest in.
- Jerk with a Heart of Gold: Aside from his schoolgirl fetish, he's actually a model citizen. Kimura can sometimes be seen picking up litter on his way home and depositing it in recycling bins, and regularly donates to charity for the sake of world peace.
- Last-Name Basis: Kimura's first name is never given.
- Loveable Sex Maniac: The guy ditched his own class to sit in on Minamo's, so he could stare at the girls in their swimsuits. And at the Culture Fest, he wanted a glass of water from the pool where Kagura and the rest of the team were swimming.
- Nice Guy: If you can look past his crazy love of high school girls, you'll see he is a kind man.
- The One Guy: Technically, there are two or three other male characters who are seen more than once, but they don't have names. He's also the only male character who appears in the opening, besides Chiyo's dad.
- Opaque Lenses: All the time. Not once do you see his eyes, or what he looks like without his glasses.
- Pet the Dog: Often. However, he ruins almost every single of these moments with a disgusting line.Mr. Kimura: Well, now that I donated $100 to the orphanage, let's go for some peeping!
- Stealth Hi/Bye: More like a 'Stealth Hi', as he has a habit of making sudden appearances, which usually startles the girls. Then he just sort of wanders off.
- Ugly Guy, Hot Wife: And an adorable daughter. It's notable that he actually looks much more normal when his perpetually-slackjawed expression isn't present.

A girl who sits in the background most of the time. Her best friend is Chihiro, but she really admires Sakaki.
- Big "NO!": Invoked when she sees a picture of Tomo sleeping in the same bed as Sakaki. Since Tomo tosses and turns in her sleep, the picture makes it seem as if she's cuddling with her (at 0:47-1:03).
- Cannot Spit It Out: Kaorin has a major girl-crush on Sakaki, but never manages to tell her up front.
- Demoted to Extra: Despite numerous attempts to avoid it.
- Dull Eyes of Unhappiness: On the first day of her third year in high school:Kimura: I'm Kimura, Class 4's homeroom teacher.
- Fangirl: Of Sakaki.
- Have I Mentioned I Am Heterosexual Today?: "N-not that I am a lesbian!"
- Heroic B.S.O.D.: She has a minor one when she finds out she wouldn't be in Yukari's class for her senior year. She gets stuck being in Kimura's.
- Image Song: Two of them, surprisingly. Kaze no Mon-Ami and TeaRose de Nemurimashou.
- Immediate Self-Contradiction: It's not called "gay" the correct terminology is "lesbian", not that she is a lesbian, her feelings for Sakaki are just a "teenage thing", and she was just platonically gushing over Sakaki's coolness anyway, and just to prove she's not a lesbian: She wouldn't mind if Sakaki was a guy... Osaka became confused by that explanation.
- Loving a Shadow: She likes Sakaki because of her Aloof Dark-Haired Girl looks, thinking she's "cool". Sakaki is actually a completely different character.
- My Friends... and Zoidberg: Kaorin occasionally joins the main cast of friends but normally because of Sakaki. Otherwise she has no strong friendship with any of the main girls and vise versa. Some fans consider her as a minor character instead as one of the main girls.
- Only One Name: Just like her crush.
- Single-Target Sexuality: "Wouldn't mind if Sakaki was a guy."
- Strong Family Resemblance: Except for the differences in age and height, she looks exactly like her mother.
- Suspiciously Specific Denial: After correcting Osaka on the proper terminology, she tries to amend it by saying she isn't a lesbian.
- Throw the Dog a Bone: The dance after the first Sports Fest, which is immediately yanked away. Also, the 3-legged race in the second Sports Fest.
- Transparent Closet: It's pretty obvious that Kaorin has the hots for Sakaki, although she tries to play it off. It gets a massive Lampshade Hanging from Osaka in the 10th anniversary comics.
- Wonder Twin Powers: She and Chihiro invoke this when they reveal that they were the ones who made Chiyo's Penguin Suit for their Kitty Cafe.Yomi: "Penguin costume..?"Kaorin: (slides onscreen, pointing at herself) "Yes. For I, Kaorin-"Chihiro: (slides next to her, pointing to herself) "...and I, Chihiro-"Kaorin and Chihiro: (in unison, doing high-five) "...combined our abilities and specially made this special costume!"

Another girl who sits in the background most of the time. Little is known about her other than the fact she's Kaorin's best friend who occasionally hangs out with Yomi early on in the manga.
- Boyish Short Hair: As seen in the picture. It gets to the point that she can easily be mistaken for a crossdressing boy.
- Demoted to Extra: She starts out as a reoccurring character who is friends with Yomi and Kaorin, but as the series goes on she appears less often and by the third year she becomes a non-speaking background character, not even getting a single line of dialogue in the final episode. In the manga she straight up vanishes in the Third Year and is never seen again.
- Know When to Fold 'Em: She's forced briefly drop out during the second Sports Fest, due to spraining her ankle. But the nurse checks it out and says it's okay, in time for her to take part in the three-legged race. Problem was, Yukari had already replaced her with Sakaki. So when Chihiro tries to give Kaorin the good news, Kaorin hisses at her twice. Chihiro takes the hint and slides outta frame, wishing her luck.
- Satellite Character: To Yomi, Kaorin and Yukari.
- Shout-Out: In one of the episodes, she wears a green and white shirt and pinkish shorts, just like the main character in Spirited Away, who also happens to be named Chihiro.
- Wonder Twin Powers: Covered in Kaorin's section.
Chiyo's Dad (Chiyo-chichi)
Voiced by: Norio Wakamoto (JP), Jason Douglas (EN)
A giant floating orange-yellow cat... thing that sometimes pops up in Sakaki's and Osaka's dreams. Believed to be Chiyo's father, but it's hard to understand why he's never at the house.
- Berserk Button: "Are you suggesting that I am not a real cat?!"Osaka: You look like Mori, the previous Prime Minister!note(cue Chiyo-chichi shaking with rage)
- Don't show anything red around him. Don't tell him you have a "Cat's Tongue" either, or he'll rip it out.
- Cat Smile: His only expression.
- Gratuitous English: "HARRO, EVERY-NYAN!! HOW AH YOU! FAIN SANKYUU!!" "AH, I WISH I WERE A BIRDU!"
- Immune to Bullets: In one of Sakaki's fantasies.
- Large Ham: Thanks to being voiced by Norio Wakamoto.
- Mega Neko
- Mind Screw: We really have no idea who or what Chiyo-chichi is supposed to be, but Sakaki and Osaka have seen him independent of each other's description. Furthermore, plush toys exist of him in-universe (much to Sakaki's surprise the first time it's brought out), and Sakaki's smaller one proceeded to glow when she stopped paying attention to it...
- Or Was It a Dream?
- Perpetual Smiler: The smile (?) on his face never changes, even when he's angry.
- Surprisingly Good English: His pronunciation is actually not bad. Of course, it's Norio Wakamoto's booming voice that makes it stand out.
- Tranquil Fury
A grey cat that Sakaki often tries to pet, only for him to run away or, more often, end with her hand clenched in his bear trap teeth. Eventually, he goes out of his way to make Sakaki's life a living hell.
- Achilles' Heel: Mayaa is the one other cat that manages to scare him off. He was even about to bite Tomo's hand, but as she had just been scratched by Mayaa, he smells it, and runs off.
- Bait the Dog: During the last episode, Sakaki walks up and apologizes to him for trying to pet him when he didn't want her to. She walks off and he follows her. She notices him following her, and it looks like he'll finally let her pet him. CHOMP!
- Boisterous Weakling: He works entirely on intimidation. If you manage to scare him like Mayaa, or even just hit him on the head like Kagura, he'll run off.
- Cats Are Mean
- Cheshire Cat Grin
- Dirty Coward
- Fragile Speedster: He shows how fast he is when Sakaki just tries to take a photo of him. He literally bounces off of the walls in an alley in order to ruin her photography attempts. He can't take a hit to the head before being scared off, though. Played straight in the fan-made fighting game.
- Gang Up on the Human: Kamineko's biggest jerkass moment is when he assembles a gang of all the other neighborhood cats to attack Sakaki, and possibly Chiyo by association. Luckily, Mayaa was able to put a stop to it.
- Jerkass: Probably the biggest in the show. Not that it stops Sakaki.
- Meaningful Name: Kamineko, meaning "Biting Cat" (噛み猫).
- More Teeth than the Osmond Family
- Names to Run Away from Really Fast
- Ridiculously Cute Critter: When he's sleeping or when he just has a normal Cat Smile.
- Slasher Smile: Especially when he's approaching Sakaki and Chiyo with his newly formed gang.
- Use Your Head: He once headbutted Sakaki straight in the gut, stunning her, before latching onto her hand.
The Mihama family pet dog.
- Big, Friendly Dog: He's a "man of character". He's also big enough that Chiyo-chan can actually ride him.
- Dogs Are Dumb: Subverted, he's a smart well-behaved dog. Although he does get over excited and tried to imitate Mayaa jumping into Sakaki's chest with Chiyo. The results were predictable.
- Formally Named Pet: "-san" is a suffix meaning "Mister/Miss". He's called "Mr. Tadakichi" in the dub.
A young male Iriomote cat (a small, highly endangered sub-species of leopard cat) that the girls encounter in the last third of the series.
- Androcles' Lion: Unlike other animals, Mayaa becomes attached to Sakaki right away, but she has to leave him because he's a wild animal. Mayaa then tracks her all the way back home after his mother dies, and shows up just in time to save her from a pack of cats led by Kamineko.
- Badass Adorable: He's a cute little mountain cat, who leaves Iriomote Island to find Sakaki all by himself and scares Kamineko's gang away.
- Big Damn Heroes: Saves Sakaki and Chiyo from an attack by a gang of cats led by Kamineko.
- Cute Kitten
- Death Glare: Gives Kamineko's entire gang a truly epic one in episode 24. Less cold expression and more "take-one-step-closer-and-I'll-kill-you" kind of glare.
- The Dreaded: Mayaa scares Kamineko to the point that his mere scent is enough to make Kamineko run away.
- Gender-Blender Name
- Interspecies Adoption: Chiyo points out that his bond with Sakaki is similar to one between a son and his mother. Occurs as a result of his mother dying after meeting the girls.
- Killer Rabbit: Despite being an example of All Animals Are Domesticated, Mayaa manages to scratch Tomo so badly that she has to go to the hospital, showing that no matter how cute he is and how well Sekaki can tame him, he's still a wild, carnivorous, bad-tempered animal.
- Pet Baby Wild Animal: Unlike domesticated cats, Mayaa takes a liking to Sakaki. Sakaki initially leaves him in the wild, as she knows that the Iriomote cat species is endangered and should not be kept as a pet. However, Mayaa later found his way from Okinawa to Japan to find her after his mother was hit by a car, and is staying with Chiyo-chan until Sakaki gets her own apartment.
- Post-Victory Collapse: Happens to Mayaa after he drvies away a gang of hostile cats that were about to maul Chiyo and Sakaki.

Short for "That One Dude". You know, that one male student that shows up, sometimes in the background? He's fixed Yukari's bike and is seemingly thrown into the series whenever they need a male student? Don't blink, or you might miss him!
- Appeal to Obscurity: The only reason he's listed here.
- Demoted to Extra: In the version of the bike-stealing scene that appears in the manga released to commemorate the 10-year anniversary of the original release, Tod is replaced with a random female student.
- Everyone Calls Him "Barkeep": Male Student #1
- Hero Stole My Bike: The victim of this. In the eyes of people who consider Yukari a hero, that is.
- Nice Guy: The first time we see him, he offers to fix Yukari's bike for her. Then, she makes off with his.
- The One Guy: Even moreso than Kimura.
- Overshadowed by Awesome: Could actually be quite funny if he was given more time. Of course, the main focus is on the girls.
- Recurring Character: Actually appears◊ quite frequently◊ in the anime.◊
