The youngest and cutest of the girls, she's an 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.
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?
Cool Big Sis: She starts to look up to Sakaki this way, once she befriends 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.
Chiyo + Penguin Suit, cranks the trope Up to Eleven. Enough that, during their annual Culture Fest, it caused students from all over the school to swamp their Kitty Cafe with customers!
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.
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.
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.
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.
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.
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.
Big, Badass Wolf: Kagura calls Sakaki a "lone wolf", although Sakaki would rather imagine herself as a cute lil' puppy.
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 stewas a souvenir!
Buxom Is Better: Also subverted, as 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.
Character Development: She appears to open up more and more to her friends as the series progresses, mostly to Chiyo and Kagura.
The Chew Toy: 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 'cuz everybody expectes her to be cool and grown up because ofher appearance.
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.
I Will Protect Sakaki: Mayaa eventually finds his way back to Sakaki, in time to save her and Chiyo from Kamineko and his gang.
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, 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.
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.
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.
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: Despite what her appearance would lead you to believe, she's actually pretty soft.
At the end of their school's 5K run, she tells Chiyo she only placed 6th, because she doesn't do well at endurance events. Which is made evident when she and her class lose soundly in a game of tug-of-war against Class-5, who had Kagura on their team. And a headbutt from Kamineko was enough to knock the wind out of her and make her double over in pain.
But she's unmatched when it comes to speed. She consistently dusts the competition, during their school's annual Sports Fest. A fact which lead Kagura to want to compete with her. She's also agile, and dexterous enough that she could deflect an incoming snowball that was intended for Chiyo, by catching it without breaking it. Then switched hands in mid-turn and threw it back at Kagura (seen at 2:06-2:11)!
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 a uniform typically worn by male students, which is often used to invoke the look of a delinquent, or "tough guy" type to wear; causing Kaorin to fangasm.
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.
Stealth Hi/Bye: When cute things are involved, she'll be out of the school before you can finish your sentences.
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.
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.
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.
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! Minus the time her father made her study for a test, by threatening to cut her allowance if she flunked it.
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.
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.
Chaotic Stupid: She's definitely chaotic. The stupid part is questionable, since she isn't dumb when she actually applies herself to her studies.
Eskimos Aren't Real: Tomo believed reindeer were fictional, until Chiyo and Sakaki explained they were real.
Image Song: Sora wa Tobikiri Paradaisu and Poi Poi Peace. Also shares one with Yomi, and another with Kagura and Osaka.
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.
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.
Another noteworthy moment was when her teasing actually managed to get under Kagura's skin and hurt her feelings, and Tomo's reaction makes it clear that it was unintentional. Tomo being Tomo, she decides to cheer Kagura up by annoying her so much that she quickly forgets to be upset by a little teasing.
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 — especially Chiyo and Sakaki. She was also Osaka's Unknown Rival on Osaka's first day.
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, 'til 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.
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.
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, 'til 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.
Image Song: Sorezore no Oneway and Oishii Kimi-Tachi.
Irony As She Is Cast: Yomi can't sing, despite Rie Tanaka having a great singing voice. It's even more ironic when Yomi's image songs are sung beautifully.
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.
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. Then wound up missing the trip because she'd caught a cold from staying out so late, with the chill in the air.
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.
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.
Ambiguous Disorder: She has an unusual way of thinking, compared to most people, and her her behavior can seem a bit srange, at times, making it easy to assume she might have some sort of mental disability. Despite this, she gets only slightly below average grades at a regular school and manages to socialize somewhat normally.
Bird Run: Subverted; Osaka tries this during a relay race, 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.
Everyone Calls Her Osaka: 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, 'cuz her nickname had been posted instead.
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.
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.
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 Osaka was only half awake at the time and had planned to wake up Yukari by banging on a frying pan. She didn't realize she had picked up a knife instead.
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.
A tanned girl who joins the main cast in the second yearnote Yukari pulled strings to have Kagura in her class, along with Sakaki. Thus, stacking the odds in her favor to make sure she won the next Sports Fest. 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'sreally like. Like Sakaki, her bust size is often the source of jokes, though she tends to be annoyed, rather than embarrassed by it.
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 Breast, Big Deal: 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.
Big Eater: But 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.
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).
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.
Tender Tears: Happens twice. The first was during the incident at the second Sports Fest (see the Jerk with a Heart of Gold entry), the other happens once they've graduated and are about to leave school, becuase she'd miss her friends and her teachers.
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.
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".
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.
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.
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!
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.
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.
Corner of Woe: During the third beach episode, she is unable to help the students with studying and is even shown up by Yukari.
Heroic BSOD: 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.
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 highschool 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 swimteam not tending their noodle stall in their swimsuits, or asking for a glass of pool water that the girls had been swimming in.
Ephebophile: 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.
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.
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 pool water that Kagura and the rest of the team had been swimming in.
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 recurring guys. However, they don't have names. He's also the only male character who appears in the opening, besides Chiyo's dad.
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!
Scary Shiny Glasses: All the time. Not once do you see his eyes, or what he looks like without his glasses.
Stealth Hi/Bye: More like a 'Stealth Hi', as he has a habit of making sudden appearances, which usually starles the girls. Then he just sort of wanders off.
Suspiciously Specific Denial: After correcting Osaka on the proper terminology, she tries to amend it by saying she isn't a lesbian. She goes on to say that wasn't what she was implying and plays it off as "a teenage thing". Then, after a moment's pause, she adds she wouldn't care even if Sakaki was a guy. Even Osakacould see through that.
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 Penguine 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 ans specially made this special costume!"
Exit, Stage Right: 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.
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...
Although Osaka was present when Sakaki gave Chiyo a plush of her "father", so she probably just remembered that and let her imagination do the rest.
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.
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.
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.
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!
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.
A young male Iromote (a small, highly endangered sub-species of leopard) cat that the girls encounter in the last third of the series. Due to his status as a very late arrival, he is a walking spoiler, so beware unmarked spoilers.
Short for "That One Dude". You know, that onemale 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!
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.
