Sakaki is a tall, long black-haired, sharp-eyed, (black eyes, and 27 years old.) attractive and soft spoken Woman that feels uncomfortable with her height and busty physique. Because of her shyness, she seldom speaks, only speaking a few phrases. Her voice is low, calm, polite, with pauses like she's thinking carefully, reticence that is misinterpreted and admired as "tough", "mysterious", and "cool," a reputation compounded by her natural athletic ability. However, her true personality is quite the opposite. while mistaken for being aloof and surly, she's actually very kind, polite, compassionate and gentle, cares a lot for her friends, and has a deep, wholesome admiration for animals, notably cats. She is the subject of Kaorin's (largely unspoken and non reciprocal) infatuation. In contrast to what other students think of her, Sakaki has no interest in sports and has a secret passion for all things cute which she eventually admits to Chiyo. Despite her shy, reserved nature, she has a very strong desire for friendship, leading her to attach herself to the group.

She is also very intelligent and academically gifted, being third in her class. Not infrequently, however, she's shown to be quite the airhead; next to Osaka, she's the character who has her head in the clouds the most, daydreaming about the cute things she's quite obsessed with.

Sakaki is unusually ample figured and tall. her height is given as 174 centimeters (approximately 5'8") and "still growing", which is extraordinarily tall for a Japanese woman. Also, she is very self-conscious about her body. Osaka notes that they "have an American among them" because of her large breasts. In the girls' locker room parlance, those with medium-sized breasts, such as Yomi, are referred to as "Hawaiian;" those with flat chests, such as Osaka or Tomo, are referred to as "Japanese." She is also planning to become a veterinatian, or a flower shop keeper.

she now occupies as a professional veterinarian, and owns an apartment, with Maya as her companian. She becomes even more taller than before, being 189 centimeters in height.

Sakaki's passion for cute things encompasses animals both real and stuffed (she gives her own stuffed animals names, like a small child). Once, having heard that Sakaki liked bears, Yomi buys Sakaki a can of bear stew, to her horror. Sakaki is particularly taken with cats, but cannot have one at home because her mother is allergic. Unfortunately, cats hate Sakaki for unknown reasons — one in particular, a gray cat known as Kamineko, delights in luring her close so he can bite her. Kagura theorizes cats think her hand smells like fish. Sakaki is often seen with Chiyo and her Great Pyrenees, Mr. Tadakichi who lets her pet him.

Sakaki is perceived as a mysterious, intimidating, and cool athlete, a reputation she secretly loathes. Her tall stature, taciturn nature, and natural athletic prowess lead others to believe she is aloof, tough, and self-assured. She is the object of classmate Kaorin's unrequited crush and the athletic rival of the highly competitive Kagura, who both see her as a figure of awe. This public image, however, is a complete fabrication built on her extreme shyness and reserved demeanor, which makes it difficult for her to express her true, gentle self. Sakaki is, in fact, a deeply sensitive and kind person trapped behind an intimidating facade, a fact that only her closest friends gradually come to understand.

Her true personality is defined by a deep, almost obsessive, love for all things cute and cuddly, particularly animals. Despite her fierce appearance, she secretly daydreams about cute creatures and loves stuffed animals, which she has on display in her bedroom. She is a dedicated but perpetually unsuccessful cat lover, often showing up to school with fresh scratches and bites from her failed attempts to pet the local strays.

her quiet nature is also the source naive and slightly odd worldviews, putting her in the same category as the perpetually distracted Osaka. While she is a top student and an exceptional athlete, Sakaki is often prone to flights of fancy and bizarre misunderstandings. A prime example is her persistent, dream-based belief that the floating, yellow, cat-like creature she sees is actually Chiyo-chan's father, which she states with an unwavering seriousness. This deadpan delivery of odd observations and fantastical theories provides much of her quiet, deadpan humor, contrasting starkly with the stoic image others have of her.

Sakaki is a loyal and protective friend, particularly toward the much younger Chiyo. She has a strong bond with Chiyo, admiring her effortless cuteness and openness, and often taking on a "cool big sister" role. Sakaki's protective instincts are showcased during a snowball fight and a school sports festival, where she becomes visibly angered by rivals mocking Chiyo's poor athletic performance.

she struggles to reconcile her perceived persona with her real one. She feels insecure about her height and busty physique, wishing she could be small and openly cute like Chiyo. This mutual envy, where Chiyo wants to be taller and Sakaki wants to be smaller, is a key dynamic that explores teenage body image and the desire to be understood.

Sakaki also likes the Neco Coneco (Japanese: ねここねこ "Neko Koneko"), a popular stuffed animal franchise. The typical example is a white cat with a white kitten sitting on its head, but it also comes in different versions and sizes, such as a sleeping Neco Coneco or an Iriomote Neco Coneco. Chiyo has also been seen wearing a Neco Coneco T-shirt. Sakaki adores the brand, much as she does all cats. Sakaki even owns a towel with a little neco coneco sticker on it. Kagura, however, often draws eyepatches or scars on Sakaki's bad doodles of the cats whenever she isn't near her notebook.

Maya (マヤー Mayā) is Sakaki's pet Iriomote Mountain cat. He has brown fur, with black tiger-like stripes with an unemused expression. He was the first cat to ever let Sakaki pet it. They were together all the time during Class 3's visit to Iriomote, and when they had to go home, Maya followed them. Apparently, Maya's mother was run over, and Maya saw Sakaki as a brand new mother. She cannot take him to her parents due to her mother's cat allergies.

Kaorin is a short-haired shy girl, a bit anxious, not super outgoing. She has a crush on Sakaki (unrequited) which is a recurring theme. Her feelings are handled sweetly but also with embarrassment, because she doesn't always know how to express them. She is interested in arts/crafts, astronomy sometimes, etc. She's not one of the main sporty or academically obsessed ones; more on the softer, artistic/emotional side.

Chiyo Mihama: Orange hair, with pig-tails. Also called Chiyo-chan. She's a child prodigy who skipped five grades, (now 19 years old) Extremely smart, responsible, kind, polite. But she also has the innocence and naivety of a child. She sometimes worries she'll be a burden or that she doesn't fit in with the older girls. She isn't very athletic (especially given that everyone else is older and taller) and often fears being physically "weak" or slow. She is now travelling to America for university.

Tomo Takino has short blackish-brown hair with slightly curled spikes at the ends. She has large, dark brown eyes, and fair skin. Her build is of medium-short height for a Japanese women. Tomo is energetic, hyperactive one. Loud, impulsive, always up to something, always trying to stir the pot or do something "fun" (sometimes at the expense of others' comfort). Very competitive. She tries to challenge others (academically, in sports) often just for the sake of competition. She's not always consistent or disciplined. Tomo is now a policewoman, even plans to join Interpol.

Koyomi "Yomi" Mizuhara bears brown long hair and sports glasses, also the second tallest in the group. The "normal" but levelheaded one. More mature/grounded compared to Tomo. She often reacts to Tomo's antics, sometimes exasperated; she's more responsible, tries to study, worries about practical things. She's self-conscious about her weight (wants to lose weight), often critical of herself and others but in a way that shows she cares.

Kagura is tan skinned, and short-haired tomboy. The sporty, athletic rival to Sakaki. She loves competition, especially in sports. Wants to push herself, often motivated by rivalry. Not as academically strong as some of the others, but tries in her way. More physical, more energetic (though more disciplined in sports. Her relationship with Sakaki is interesting: admiration + rivalry + respect. She sometimes pushes Sakaki, sometimes is frustrated. While Kagura is driven by competition, she is sweet and sensitive and can be brought to tears, especially when she feels she's let someone down or during emotional situations.

Ayumu "Osaka" Kasuga has medium-length brown hair, and is now posing as a gym teacher at 20. "Osaka" is her nickname (comes from her being from Osaka). She is kinda spacey, slow to respond, dreamy, often not fully "on top" of things — in a cute, laid-back way. Her humor comes from misunderstandings, her imagination, being lost in her own head, taking things literally, etc. She isn't good with sports or studies (compared to some of the others), but she has her own charm; she's well-liked and accepted. She has a small tongue, and is sensitive to spicy food. She is also really stiff, and uses the Osaka dialect.

Yukari Tanizaki is a brown long, brown wavy-haored adult. She is not only the girls' English and homeroom teacher (class 3), but a teacher with very unconventional methods and a rather close relationship with the class. Her students are casual enough to call her by her given name (Yukari-sensei in lieu of Tanizaki-sensei, with a few, mostly Tomo, addressing her as the extremely informal Yukari-chan (Japanese); just Yukari in English). Depending on the day, time, and her mood, she can be either a horrible tyrant or one of the sweetest, most touching teachers ever. Her behavior ranges from mercilessly teasing Chiyo and hitting students with blunt objects to kind and gentle words and simple, encouraging notes on tests telling students she believes in them.[citation needed] She is often selfish, irresponsible, miserly, generally dysfunctional, and also easily angered, and shamelessly expects her friend and fellow teacher, Minamo Kurosawa ("Nyamo"), to not only tolerate all of this, but to enable it. Yukari's car, the "Yukari-mobile", Technically, it belongs to Yukari's parents. At one time a nice silver Toyota Corolla, Yukari's reckless driving habits have turned it into a scarred, beaten vehicle. Even the mere mention of the Yukari-mobile can cause terror and flashbacks to anyone who has ridden in her car. Chiyo in particular goes to extraordinary lengths to avoid riding in it or any other vehicle Yukari might possibly be driving. However, Tomo enjoys riding in it.

Minamo "Nyamo" Kurosawa is a Physical education teacher, friend of Yukari from before. More grounded, more composed. She acts as a contrast to Yukari. More mature in behavior; also has her own vulnerabilities. Doesn't always stay serious but generally more responsible. "Nyamo" is a nickname from Kurosawa's student days, but Yukari calls her that, and so does Tomo Takino. Other students call her Kurosawa-sensei, but later on, most of them start calling her Nyamo as well (though they still use the more polite "Nyamo-sensei" instead of Tomo's extremely impolite "Nyamo-chan").
