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, with a high-pitched voice that makes ears bleed. A ten-year-old child prodigy who transfers to Yukari's class and always seems to get the highest scores and is the go-to person for questions but is (almost) bottom in sports. She comes from a rich family, with a large house in town and a summer house by the beach, but her (human) parents are never seen. Rather than being spoiled, some characters think she turned out to be the perfect child (from a parent's perspective) as she is extremely intelligent and responsible, making her own breakfast and lunch, waking up her parents, taking care of her dog, etc.


 * Adorably Precocious Child
 * Anthropomorphic Cat's Cute Daughter
 * 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.
 * Big Friendly Dog: Mr. Tadakichi, a "man of character".
 * Butt Monkey: Tomo and Yukari walk all over her.
 * Cheerful Child: Her picture's literally the first thing you'd think of (and see) when you see that trope.
 * Child Prodigy
 * Everything's Better with Penguins: Chiyo + Penguin Suit = Weapons-Grade Cute.
 * Expressive Hair: Osaka is fascinated with her pigtails.
 * Fear of Thunder
 * Girlish Pigtails: Osaka wonders if they're alive...
 * Human Mom, Nonhuman Dad: Uhh...maybe...
 * Image Song: FIVE of them.
 * Implausible Hair Color: Trope image. She has red hair in a realistically-colored series.
 * Improbable Age
 * 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. Which in it self is hilarious considering the fact that Sakaki wants to be just like her.
 * Kawaisa
 * 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.
 * The Ojou
 * Token Mini-Moe
 * Why Did Yukari-sensei Have To Drive?
 * Wise Beyond Her Years

Sakaki
 Voiced by: Yuu Asakawa (JP), Christine Auten (EN)  The quiet, tall girl who sits in the back of the class. At first, people think she's mean because of her looks, but nothing could be further from the truth. Has extreme Cuteness Proximity bordering on Osaka-level daydreaming, especially with animals (and especially kittens) and Chiyo. Too bad her mother is allergic to cats. Exceptionally athletic (all the sports clubs want her to join), she wins her sports festival events by talent and determination rather than training. Also gets good grades. These last two seem unfair to Kagura.


 * Animals Hate Her: At one point, she looks at her scarred hand and comments that she "might not get off so lightly" if she encounters a wild cat, instead of the domestic variety.
 * Mr. Tadakichi likes her though.
 * Badass: It's just that she'd rather be Badass Adorable instead.
 * She is cute, though, just not enough for the other characters to call her that (Except for Chiyo, in the anime).
 * Big Badass Wolf: Kagura calls Sakaki a "lone wolf", although Sakaki would rather imagine herself as a cute lil' puppy.
 * Big Breasts, Big Deal: Type 1.
 * Blue with Shock: She gets this either when she is thinking of something that's impossibly cute, or when Kagura or Tomo's actions catch her off guard.
 * Boobs of Steel
 * Broken Ace
 * Buxom Is Better: A subversion, as Sakaki dislikes the large amount of attention her bigger size draws. Life's tough when your less endowed friends talk about them all the time.
 * 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
 * Cool Big Sis: Towards Chiyo, especially as the series progresses.
 * Covert Pervert: She looks a bit too eager to hear Yukari and Nyamo's "stories".
 * Although, afterwards, she is too embarrassed to even look into Nyamo's face on the following morning.
 * Cuteness Overload: Very, very prone to this, usually around cats.
 * Or around Chiyo in her penguin costume, but so are all her classmates
 * Dandere: She tends to unintentionally intimidate people with her reticence.
 * Daydream Believer: Really believes that Chiyo's father is a yellow cat because of her dreams.
 * 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.
 * Even the Girls Want Her
 * Face of a Thug: Sakaki only looks Tall, Dark and Bishoujo.
 * Fear of Thunder: Earthquakes, construction workers, and horseflies too.
 * 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.
 * Gainaxing: When warming up.
 * Genius Bruiser: Only bested by Chiyo and possibly Yomi in this regard.
 * Gentle Giant
 * Girls Love Stuffed Animals
 * Hachimaki: Subverted in the last Sports Festival episode. She starts off wearing it as normal around her head then,.
 * Hot Chick in a Badass Suit: Her gakuran costume during the third athletics festival is enough to reduce Kaorin to yelling "HOORAY!" over and over again.
 * Huge Schoolgirl: See below.
 * 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 unintentionally-intimidating attitude causes the girls to mistake her for one.
 * Kindhearted Cat Lover
 * 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: Ouite often, mostly in response to seeing kitty cats!
 * Misunderstood Loner with a Heart of Gold
 * Odd Couple: with Kagura, although it does not stand out as much as Yomi's and Tomo's friendship.
 * Pet Baby Wild Animal: Mayaa.
 * The Quiet One
 * Rapunzel Hair
 * Screams Like a Little Girl
 * Schoolgirl Rival: Kagura engages Sakaki when she first transfers into the class, and Tomo tries this with predictable results.
 * Shoo The Cat: Sakaki must do this to Mayaa before leaving Okinawa.
 * Shrinking Violet: She generally only opens up to Kagura and Chiyo.
 * Squee: Whenever cats 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.
 * Sugar and Ice Personality
 * Tall, Dark and Bishoujo
 * Tsurime Eyes
 * Unknown Rival: To Kagura, even after she introduces herself as such. Despite this, the two become close friends.

Tomo Takino
 Voiced by: Chieko Higuchi (JP), Mandy Clark (EN)  The extremely-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, though not out of malice (well, not more than any other teenager). Is best friends with Yomi, though it's unclear how the two of them manage to stand each other.


 * A-Cup Angst: She's nowhere near the flattest character on the show, but Yomi's always mocking her breast size anyway. She does start quite a number of perverted jokes though (more in the manga). A few of them are about Sakaki's, Kagura's, and Yomi's breasts. Maybe she's envious? She jokes that she'd do better in sports like the aforementioned if she had Kagura's figure.
 * Tomo's definitely jealous, particularly of Sakaki's size, as she laments being in the same "group" as Osaka, and is ecstatic whenever her own size increases. She's also obsessed with Kagura's large bust.
 * In the dream episode, you can quite clearly see that in her dreams, she's a lot bustier than normal.
 * Her personal idol: Fujiko Mine.
 * Alliterative Name
 * Baka: Is at times the recipient of this insult, except, in one amusing case, where she is the one screaming it with glee in response to one of Yomi's annoyed remarks.
 * 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
 * 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 actually being stupid.
 * Cosplay: As a giraffe, much to the annoyance of Yomi and Minamo.
 * Expository Hairstyle Change: Every school year.
 * The Friend Nobody Likes
 * 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 Jerkass 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.
 * Important Haircut: They mean nothing, and Yomi cracks up at the prospect, since the most common reason for this in Real Life Japan is getting a new boyfriend.
 * It Amused Me: This seems to be the motivation for her behavior, given that she decided to study hard for a test with no other reason than to spite Yomi.
 * Large Ham
 * Mega Manning: An Imagine Spot shows the viewers what might happen if Tomo copied Sakaki's athleticism, Chiyo's book smarts and Osaka's strangeness.
 * Not So Different/Expy/Counterpart Comparison: Her and Yukari.
 * Odd Couple: With Yomi.
 * Pet the Dog: At the graduation ceremony, after years of teasing Chiyo, Tomo stands up and leads the crowd in a round of applause for her.
 * 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 annyoing her so much that she quickly forgets to be upset by a little teasing.
 * 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.
 * Screwy Squirrel
 * Standing in the Hall: Self-inflicted.
 * Too Dumb to Fool: Of all people, Osaka finds this out in her one attempt to prevent the "Osaka" nickname from spreading. She points out how little time she's lived in Osaka as a reason to not call her that. A smart person would note that all of the locales listed are just suburbs of Osaka. Tomo just gets too confused by all the places and sticks with the one she can remember.
 * 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.

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. Best friends with Tomo, and has a surprisingly-high tolerance level for her shenanigans. Often plays the Straight Man and becomes stern or angry when others cross the line. Enjoys food and, as a result, always seems to be on a diet.


 * Beautiful All Along: Even with glasses. Especially with glasses.
 * Berserk Button: Don't call her stupid, and never, ever, call her fat.
 * Brainy Brunette
 * The Comically Serious
 * Cross-Popping Veins: Quite often, due to Tomo's antics.
 * Deadpan Snarker: While she might put up with Tomo, she spends plenty of snark on her actions.
 * Dreadful Musician: Considering her Seiyuu's musical skills, this is very ironic by itself.
 * And an Actor Allusion considering most of the characters she voices can't sing.
 * Genius Bruiser
 * Girlish Pigtails: In the supplementary lessons.
 * Hollywood Pudgy: Constantly dieting and being teased by Tomo, but she definitely isn't fat by any means. Just see Beautiful All Along.
 * Hollywood Tone Deaf: Yeah, right...like Rie Tanaka can really sing that badly.
 * 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: Not quite as fast as Sakaki, not quite as strong as Kagura and not quite as smart as Chiyo. Heck, it's even reflected in her bust size: big, but not the biggest. Tomo mocks her for her JOAS status in the Tsukurimashou image song.
 * Meganekko
 * Not So Above It All: Yomi behaves just as childish as the others when she is about to find out her exam results in the last episode.
 * Not So Different/Captain Ersatz/Counterpart Comparison: To Nyamo.
 * Odd Couple: With Tomo.
 * Only Sane Girl
 * Ordinary High School Student
 * Scary Shiny Glasses: Subverted — they're her equivalent of Blank White Eyes.
 * Shoryuken: Delivers a few to Tomo when she gets sick of her antics. They knock Tomo out cold.
 * Sick Episode: She misses out on the girls' trip to Magical Land because of a fever.
 * Straight Man
 * Trademark Favourite Food: Curry. Heck, anything spicy.
 * Vitriolic Best Buds: With Tomo.
 * Weight Woe
 * Why Did It Have To Be Cicadas?
 * Zettai Ryouiki: Behold.
 * It may be worth pointing out that, in the supplementary lessons, she comes close to reaching Grade S. She is not a Tsundere, however.
 * Maybe toward Tomo...

Ayumu ("Osaka") Kasuga
 Voiced by: Ayako Kawasumi (JP web short), Yuki Matsuoka (JP series), Kira Vincent-Davis (EN)  As her (forced) nickname suggests, Ayumu Kasuga is a transfer student from Osaka. It's not actually her real name and she lived there for only one year, but she was no match for Tomo's enthusiasm and thick-headedness. Sometimes lapses into non-sequiturs when speaking, and often gets lost daydreaming. Isn't the sharpest crayon in the box and is even beaten by Chiyo at sports, but has a knack for puns and riddles and pun-based riddles. Without question, one of the most popular characters in the show.


 * A-Cup Angst: Could you imagine that she felt like Chiyo betrayed her when Yomi pointed out that Chiyo was only flat because of her age, and that she might become as well-endowed as Sakaki when she get older?
 * Berserk Button/Serious Business: If she tells you to break your chopsticks correctly, you better break them correctly.
 * Lampooned in this vid.
 * 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
 * Butt Monkey: The only reason why she isn't so miserable is because she's in blissful orbit so often.
 * Cloudcuckoolander: The Trope Codifier and Trope picture.
 * The Cuckoolander Was Right: Here. It may look like a big case of Freud Was Right to some readers, but...
 * Covert Pervert: Has shades of this, considering some of the innuendos she comes up with.
 * Not so covert, she was the one, who asked Nyamo the question that made her do the apperently very explicit The Talk and was listening very closely, as her classmates did and also did appreciate it very much like her classmates.
 * Does Not 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.)
 * Engrish: "OH MY GAH!"
 * Ensemble Darkhorse
 * 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's Osaka within moments of her first appearance once Tomo decides to nickname her. It's bad enough that the school (or at least Yukari) can't remember her real name, either.
 * One hilarious moment from the manga shows her looking at the class lists one year, she was looking for "Ayumu Kasuga", but wasn't there, leading her to believe she wasn't in a class with any of her friends. Turns out she got listed as "Osaka".
 * The Fool
 * Fountain of Memes
 * Hey, It's That Voice!: Osaka, our cute little Cloudcuckoolander, also happens to share a voice with a certain Psychopathic Manchild
 * 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 and Time Pavement. Also shares one with Chiyo.
 * Kansai Regional Accent: Becomes a Texan accent in the English dub.
 * The Klutz
 * My Name Is Not Osaka
 * 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.
 * Nightmare Fuel Station Attendant: But we love her anyway!
 * Not a Morning Person
 * Only Known By Her Nickname: Starting in Second Year, even the official school roster calls her "Osaka". In the anime, she's known as Osaka from her first day.
 * 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
 * Slasher Smile: This.
 * Sleepyhead: Dozes off in class, on the grass, on the school roof, under a kotatsu, on her textbook...
 * Tareme Eyes
 * Terrible Artist

Kagura
 Voiced by: Mitsuki Saiga (JP web short), Houko Kuwashima (JP series), Allison Sumrall (EN)  A tanned girl who joins the core class in Second Year (because Yukari wanted to win the Sports Fest). Like Sakaki, she's very athletically inclined. She is the only main character not in the Go Home Club, spending a lot of time training for the swim team (which makes Kurosawa her coach). She becomes very good friends with Sakaki. Sideburns never looked so cute.


 * Big Breasts, Big Deal: Type 1.
 * Big Eater: But doesn't gain weight, to Yomi's disgust.
 * Boisterous Bruiser
 * Boobs of Steel: She's very close to Sakaki on an athletic scale, and she's quite powerful.
 * Bokukko
 * Book Dumb
 * 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.
 * Early-Bird Cameo
 * Foe Yay: Kagura REALLY likes asking Sakaki for a challenge, even if it's over something as trivial as flowers.
 * Go Nagai Hairlocks
 * Gratuitous English: "You Are A Fool!" "Attack!" "I am super baka".
 * Image Song: 'Ashita wa Makenai! Go! Friend!' where she sings about Sakaki, and 'Lazy Crazy Bonkuraazu', where she leads Tomo and Osaka.
 * Jerkass: Nowhere near Tomo or Yukari's level, and even then only really in the manga.
 * Magic Skirt
 * Ms. Fanservice
 * Odd Couple: With Sakaki.
 * Sixth Ranger: She joins the group in Second Year.
 * Tan Lines: During the Summer arcs.
 * Tender Tears: Occasionally sheds a few over remorse or sadness.
 * Tomboy
 * Tomboy and Girly Girl: She and Sakaki are a subversion, as Kagura only sees glimpses of her friend's real personality.
 * Tsurime Eyes
 * Unknown Rival: To Sakaki. Occasionally becomes a regular rival to Tomo, just because they're both addicted to competition.
 * You Go, Girl!

Yukari Tanizaki
 Voiced by: Akiko Hiramatsu (JP), Luci Christian (EN)  The girls' homeroom teacher throughout all three years of their high school career and also teaches English. She tries to act as a teacher and "best friend" to them. Not the most responsible of teachers, she is often late because she wanted to buy a video game or wanted to sleep in, and has been known to cancel class to do P.E. instead. Is fiercely competitive with phys-ed teacher and long-time friend Minamo Kurosawa. She is an absolute terror behind the wheel, and has traumatized more than one student with her crazy driving (Tomo is th eonly one, whoe approves of her style of driving... Due to her being three fries short of a happy meal, too).


 * Adult Child
 * Best Beer Ever
 * 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.
 * Bottle Fairy
 * Can't Hold Her Liquor
 * Christmas Cake
 * Conspicuous Consumption: To the point where she'll aggressively attack anyone fortunate enough to have experienced them before her.
 * Drives Like Crazy: 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.
 * Evil Laugh
 * Foe Yay: Towards Nyamo.
 * Genius Ditz: Possibly.
 * Gratuitous English: Inconsistently Dubbed into Gratuitous Spanish. Justified slightly, because she is an English teacher.
 * 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: In the finale, especially her words to Kagura.
 * 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.
 * Jerkass: Picture adult Tomo.
 * 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
 * Maximum Fun Chamber: Yukari's car.
 * Noodle Incident: She occasionally teases Nyamo about an incident involving a love letter.
 * Not a Morning Person
 * Not So Different/Expy/Counterpart Comparison: Her and Tomo.
 * 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.
 * Sensei-chan: Quite possibly the Trope Codifier.
 * Tomboy and Girly Girl: She and Nyamo are the adult versions of this trope.

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 being single and unmarried.
 * 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.
 * 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.
 * 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.
 * Reasonable Authority Figure: The only one the show has.
 * 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/Captain Ersatz/Counterpart Comparison: To Yomi.
 * Only Known by Their Nickname
 * Sensei-chan
 * The Straight Man
 * Tomboy and Girly Girl: She and Yukari are the adult versions of this trope.
 * Tomboyish Sidetails
 * You Go, Girl!: The adult version of this trope.

Mr. Kimura
 Voiced by: Kouji Ishii (JP), Andy McAvin (EN)  The only male teacher on the campus who appears most of the time. Wears short-rimmed glasses and almost always has an open-mouthed stare. Has a thing for HIGH SCHOOL GIRLS! (Especially Kaorin.) Has a beautiful, loving waifu, a cute daughter, gives to charity, picks up garbage, and loves peeping.


 * Cloudcuckoolander: Is shown to occasionally have moments that call his clarity into question.
 * Dirty Old Man: And we repeat, he became a teacher CUZ HE LIKES HIGH SCHOOL GIRLS AND STUFF.
 * Ephebophile: Not lolicon...most of the time. See below.
 * Evil Laugh: If he's not evil, then he sounds freaking maniacal.
 * Fetish: For high-school uniforms, apparently.
 * Gonk
 * Gratuitous English: Mai waifu.
 * Hot for Student: Poor Kaorin...
 * Jerk with a Heart of Gold: Well, disgusting pervert who is otherwise a kind, model citizen anyway.
 * Jerk with a Heart of Jerk: One of his lines can be paraphrased as "Well, now that I donated $100 to the orphanage, let's go for some peeping!".
 * Lolicon: "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.").
 * Loveable Sex Maniac
 * Nice Guy: If you can look past his crazy love of high school girls, you'll see he is a kind man.
 * No Accounting for Taste: 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).
 * 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.
 * Scary Shiny Glasses
 * Stealth Hi Bye
 * Ugly Guy Hot Waifu: And an Adorable Daughter.

Kaori ("Kaorin")
 Voiced by: Sakura Nogawa (JP), Tiffany Grant (EN)  A girl who sits in the background most of the time. Is friends with a girl named Chihiro, but really adores Sakaki.


 * Bi the Way: She's either bisexual or Single-Target Sexuality for Sakaki. She "wouldn't mind" if Sakaki were a man.
 * Alternatively, she's a closeted lesbian and the "man" part was to sound Heterosexual and justify her "admiration". And she failed quite badly.
 * Bob Haircut
 * 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.
 * Fan Girl
 * Have I Mentioned I Am Heterosexual Today?: "N-not that I am a lesbian!"
 * Heroic BSOD: She's not in Yukari's class as a senior. It Got Worse: she's in Kimura's.
 * Image Song: Two of them, surprisingly. Kaze no Mon-Ami and TeaRose de Nemurimashou.
 * Schoolgirl Lesbians: Kaorin really, really adores Sakaki, but Sakaki fails to notice.
 * Single-Target Sexuality: Wouldn't mind if Sakaki was a guy.
 * Supposedly.
 * Straight 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: Current page image.
 * Yandere: Possibly...

Chihiro
 Voiced by: Akane Omae (JP), Hilary Haag (EN)  Another girl who sits in the background most of the time. Kaorin's closest friend, and is embarrassed about having to get homework help from Chiyo.


 * Bifauxnen
 * Satellite Character: To 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.
 * Why Did It Have To Be Cockroaches?

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 Osaka's and Sakaki's dreams. Believed to be Chiyo's father, but it's hard to understand why he's never at the house.

"Osaka: You look like Mori, the previous Prime Minister! (cue Chiyo-chichi shaking with rage)"
 * Berserk Button: "Are you suggesting that I am not a real cat?!"


 * Don't show anything red around him. Don't tell him you have a "Cat's Tongue" either, or he'll rip it out.
 * Gratuitous English: "HARRO, EVERY-NYAN!! HOW AH YOU! FAIN SANKYUU!!" "AH, I WISH I WERE A BIRD!"
 * Surprisingly Good English: His pronounciation is actually not bad. Of course, it's Norio Wakamoto's booming voice that makes it stand out.
 * Large Ham: Duh!
 * 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...
 * One-Scene Wonder: Shows up in maybe five skits total. Everyone that knows this show will remember him without fail.
 * Or Was It a Dream?
 * Parental Abandonment
 * Slasher Smile: The smile(?) on his face never changes, even when he's angry.

Kamineko
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 she had just been scratched by Mayaa, he smells it, and runs off.
 * Cats Are Mean
 * Cheshire Cat Grin
 * Cowardly Lion: 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 ally 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!
 * 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 headbutt Sakaki straight in the gut, stunning her, before latching onto her hand.

Tod (Male Student #1)
 Voiced by: Greg Patton (EN)  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"
 * Hero Stole My Bike: The victim of this. In the eyes of people who consider Yukari a hero, that is.
 * The One Guy: Even more so than Kimura.
 * Ordinary High School Student: Sorry Yomi, but even you couldn't beat the normality of Tod.
 * 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.
