Igo-Soccer Club: a completely invented sport that combines the traditional game of Igo with soccer. It technically has no rules that the average human outside this universe would understand. Members: Kenzaborou Daiku (the president), Makoto Sakurai (the only member who actually knows how to play), Yurai (who has a crush on Kenzaborou), Ogi (a random member who knows the rules and acts as the referee), and the assigned tutor, Manabu Takasaki.
Kendo Club: Misato.
Theater Club: Kōjirō.

Science prep room: This is the room Nakamura usually uses, typically to plot to capture Nano.

Makoto Sakurai: He has short, light brown hair. He's a shrewd, observant, and manipulative young man when it suits him, though he maintains a lighthearted and comical relationship with both his family and the members of his school club. Upon joining the Igo-Soccer Club, he reveals to the club president, Kenzaborou Daiku, that Igo-Soccer is actually a real and formal sport. He also confesses to having been the MVP of the sport during his middle school years. Due to a mistake by Takasaki, Makoto discovers that the teacher is in love with his older sister. Although he doesn't understand what the teacher sees in his sister, he threatens to expose his feelings unless he agrees to become the official coach of the Igo-Soccer Club. After the teacher refuses, Makoto forces him to change his mind by bribing him with photographs of Izumi when she was younger, thus achieving his goal.

Yuria Sekiguchi: She has light blonde hair. Her eyes are drawn as two vertical black lines or bars without pupils. She is an extremely quiet, serious, calm girl with a neutral expression. Unlike the others, she maintains a very passive attitude. She belongs to the Igo-Football Club. She is secretly in love with Kenzaborou; in fact, the only reason she joined the club is because of him. She simply listens passively to Kenzaborou. She is almost always seen reading Helvatica Standard manga (a short manga of absurd jokes within this universe). She only breaks her expressionless face in extreme situations, when her mouth hangs open and her eyes roll back in shock, for example, when witnessing an absurd and ridiculous Igo-Football match for the first time.

Minoshi Tachibana: She is Misato's younger sister. She has short, dark pink hair. She is generally kind to her sister and gets along well with Misato. She tends to laugh at other people's misfortunes or embarrassments; although she tries to hold it in, she's not very good at it.

Yūko's mother: A middle-aged woman who wears glasses. She gets angry easily, especially when her daughter is silly or does bad grades. She often punishes and physically hits Yūko in a comical or exaggerated way when she misbehaves or gets on her nerves. Although she appears to be a conventional and upright mother, she shares the same absurd eccentricities as Yūko.

Mrs. Naganohara: Mio and Yoshino's mother. She is married, as she always wears her wedding ring. She has a remarkably youthful appearance, to the point that she doesn't look her age as a mother with daughters. She is known for playing Sepak Takraw, a Southeast Asian sport similar to volleyball, but in which only the feet, knees, elbows, and head are allowed to touch the ball.

Mr. Nakanojō: He owns and operates a Daifuku street stall and is the father of Tsuyoshi Nakanojō. Like his son, he suffers from a rare genetic condition where his hair only grows down the center, not on the sides. To conceal his natural mohawk, he wears a wig with a more traditional and formal hairstyle.

Kiyoshi: He is the rightful owner of Buddy (a Golden Retriever) and Co-Buddy (the small white dog). He is often seen desperately running after his dogs. This happens because Buddy and Co-Buddy constantly run away to lick, bother, or bite Yuuko Aioi.

Weboshi: She's part of Misato and Fe-chan's trio. She has dark green hair tied in a ponytail. Outside of school, she adopts a punk/tomboy aesthetic. She's a passionate and empathetic young woman who constantly supports her friends. She's in love with Tsuyoshi. Her attraction to Tsuyoshi stems from a prejudice. She mistakenly believes he's a "bad boy" or juvenile delinquent because of his haircut. Nakanojō is actually quite ordinary, boring, and skeptical. He often teases, observes, supports, or mocks Misato's complicated tsundere relationship with Kojirō.

Yoshino Naganohara: She is Mio's older sister. She is a university student. She has short-to-medium-length, shoulder-length blue-purple hair. She enjoys playing inexplicable and cruel pranks on Mio. Because of this, Mio often reacts violently, sometimes hitting her or putting her in wrestling holds. She has a strange obsession with dressing up, frequently appearing in ridiculous costumes just to scare or confuse others. She takes life with extreme calm and usually maintains a cheerful or mocking expression, regardless of the chaos she causes around her. She possesses a natural talent for kendo and claims she doesn't need to practice because training only weakens her. She is generally quite good at cooking, with the curious exception that she is incapable of making jam. She secretly follows Kojirō home just for fun. She used to be Misato's senpai in the kendo club.

Tamamura: She has long, blonde hair. She works as a cashier and promoter at Daiku Cafe. She attends the same university as Yoshino, whom she affectionately calls "Naganon." She is noticeably shy, timid, and insecure. She has serious difficulty explaining herself or dealing with pressure when cafe customers are confused or angry. Like Izumi, she has the comical trait of sweating profusely when she is nervous, impatient, or embarrassed.

Fe-chan: Everyone refers to her as Fe-chan/Fecchan. She's a friend of Misato and Weboshii. She's extremely clumsy and tries to see the bright side of everything. She's usually loud, cheerful, and somewhat naive. She often acts as the absurd character. She tends to do or say silly things that exasperate her friends, especially Misato. She loves school drama. She spends a lot of her time playfully teasing Misato about her obvious (and violent) crush on Sasahara, acting as the instigator along with Weboshii.

Manabu Takasaki: He teaches Japanese literature. He takes his teaching very seriously and appears calm, but he can be overcome by passion and panics when he has a lot of work or feels overwhelmed. He is tall and has dark brown hair. This often leads him to shout, fall over in hysterics, or behave irrationally. This happens frequently with Izumi, whom he likes, or when he is around her. When he panics, his mind goes blank, he speaks without thinking (making everything worse), and he becomes extremely anxious and agitated whenever he has the opportunity to express his feelings. This contrasts sharply with his usual serious and dedicated demeanor, a contrast that often has a comical effect.

Kana Nakamura: She is the science teacher at Tokisadame High School. At work, she wears a lab coat over a blue shirt, a black skirt, and geta sandals. Outside of work, she dresses in shorts and a hoodie, in a more casual style. She is extremely intelligent when it comes to creating gadgets, though she completely lacks common sense in everyday life and is extremely careless. Although she tries to maintain a cool and calculating facade, she blushes and becomes uncomfortable if someone tells her she looks cute. Her teaching style is improvised and carefree, to the point of forgetting she has assigned classes. She has a peculiar way of speaking and a temperament that quickly shifts from scientific obsession to frustration or extreme shyness. She knows that Nano is a robot and is determined to capture her to examine her amazing technology. She cannot accept that such an advanced robot should live an ordinary life. She designs outlandish inventions to trap her. Her extreme clumsiness causes all her plans to fail catastrophically, and she frequently falls into her own traps. She used to be Sakamoto's former owner; he was originally named Taisho. Sakamoto ran away from home because Nakamura's clumsiness caused him to have constant accidents.

Kousuke Ōura: At first glance, he appears calm and collected, taking his responsibilities seriously. Beneath his professional and strict exterior, however, lies a deep negativity and melancholy regarding his solitary and uneventful life. He is not particularly friendly or approachable, and he maintains a subtle rivalry with the school principal, secretly enjoying putting him in awkward situations or outdoing him whenever he has the chance. He is a middle-aged man and the vice-principal of Tokisadame High School who constantly seeks to usurp the principal's position.

The Principal: He is the principal of Tokisadame High School. He is an elderly man, bald (except for gray streaks at the sides) with a prominent mustache. Despite his frailty and administrative position, he possesses extraordinary strength and is an extremely talented professional wrestler. He loves telling old jokes, bad puns, and boring anecdotes that usually make the teachers and students uncomfortable or utterly bored. He is sensitive and self-conscious about his baldness.

Izumi Sakurai: She's an English teacher and homeroom teacher for Yuuko, Mai, Mio, and the others. She's a polite and gentle woman. She suffers from constant insecurity, assuming she's made a mistake and apologizing excessively. When she panics or gets nervous, she sweats profusely. Her younger brother is Makoto, with whom she's less shy and more assertive, even confronting him directly when she finds adult magazines in his room. She's deeply in love with Manabu, which leads to misunderstandings, and their extreme shyness creates comical situations. She tries to enforce the school rules seriously, but fails due to her passivity. Her students often innocently take advantage of her weakness or are bewildered by her reactions. She has no artistic talent. Her authority figure, combined with her youthful appearance and clumsiness, creates an adorable contrast.

Tsuyoshi Nakanojō: He doesn't dye or shave his hair. His hair doesn't grow naturally on the sides, only in the center, giving him a characteristic blond mohawk he inherited from his father, who owned a local daifuku stand. Due to his scientific nature, he doesn't believe in the supernatural, ghosts, or religion at all. His hobby is trying to debunk paranormal phenomena or medium scams. However, thanks to the absurd universe, every time he tries to prove that magic or ghosts don't exist, he ends up trapped in bizarre situations that confirm the supernatural, or he suffers ridiculous physical harm. He usually gets hurt or beaten up by other characters, even when he had nothing to do with it.

Haruna Annaka: Her most distinctive feature is a huge red bow. It's so conspicuous that Sakurai confronts her for breaking the dress code, but Annaka always gets away with it by cracking a joke or striking an adorable bunny pose. She's a cheerful and bright girl, but she often finds herself in absurd situations caused by strange villagers. When she's confused or surprised, her usual reaction is a drawn-out "EEEEEEEEEEEEEEHHHHH?!" She tends to lose her temper when given impossible or ridiculous orders by her superiors, but she ends up accepting them, completely bewildered. She demonstrates excellent aim. She enjoys reading manga and subscribes to the local newspaper, Tenkawa.

Kenzaburō Daiku: President of the Igo-Soccer Club. Legitimate heir to the colossal Daiku Zaibatsu (Daiku Corporation). He is a cheerful, easygoing, and kind-hearted boy, but with an alarmingly low level of direction or real motivation. Despite his wealth, he attends an ordinary school. He founded the Igo-Soccer Club with the idea of ​​merging the board game Go with soccer. After Makoto joins the club, she discovers that Igo-Soccer is a real and official sport with absurd and complex rules. Yuria, a member of the club, is secretly in love with him, a fact he doesn't realize due to his nature.

Kōjirō Sasahara: He's incredibly eccentric, acting, speaking, and dressing like a sophisticated and wealthy aristocrat. Despite his delusions of grandeur, his family isn't royalty; they're just local farmers. He's the president of the drama club, proposing absurd ideas. He travels riding a white goat, also named Kōjirō, in his honor. He's accompanied by a "butler" named Hirose, who's just a farmhand working for his family, pandering to him and attending to his strange requests. Misato is deeply in love with him. Being an extreme tsundere, she's easily embarrassed and expresses her feelings by shooting him with heavy military weapons (machine guns, bazookas, grenades, or missiles). Thanks to the absurd logic of this world, Sasahara always survives almost unscathed. Although he has hardly any close friends and is seen as a weirdo, the girls consider him the idealized 'Prince Charming' and willingly ignore his everyday antics. He used to go to kendo classes with Misato, but not anymore.

Misato Tachibana: She acts extremely cold, rude, and violent to hide her feelings. She is deeply in love with Kojirō, who doesn't seem to notice. When she feels exposed or someone mentions her crush, she reacts with immediate anger. Misato often conjures military-grade firearms out of thin air and riddles Sasahara with bullets or blows him up whenever she gets nervous. She has fired Gatling guns, automatic pistols, assault rifles, anti-tank rocket launchers, hand grenades, and even a cannon. Sasahara always survives and is only left covered in soot or flour. Her best friends (Fe-chan and Weboshi) often play pranks on her to make her angry. Minoshi is Misato's younger sister. Despite being smaller, she is much more mature and calm, and constantly teases Misato about her lack of self-control. She maintains a friendly rivalry with Toshino in kendo class.

Hakase (The Professor): Her real name is unknown, as Hakase means "The Professor" in Japanese. She is a genius scientist and the founder of the Shinonome Research Laboratory. She lives in the laboratory with her android Nano and Sakamoto. She doesn't attend school because she has already graduated thanks to her superior intellect. Despite her exceptional intelligence at only eight years old, she is capricious, throws tantrums if she doesn't get what she wants, and manipulates Nano to get sweets. She is fascinated by sharks and glue. She loves snacks, especially omurice and pudding. She is afraid of dogs. She lives alone without parental figures, justifying her free and spoiled attitude. She adds modifications to Nano without her consent and invented a red scarf for Sakamoto that translates from feline to human. She has orange hair and always wears a noticeably oversized white lab coat, which she only takes off to sleep.

Sakamoto: He's a cat. His original owner was Kana Nakamura, who originally named him Taisho. He ended up escaping from her house due to the teacher's constant carelessness and accidental "experiments." He was found by Hakase and Nano in a box. Hakase decided to name him Sakamoto simply because that was the name on the box. To communicate with him, Hakase invented a red handkerchief that instantly translates meows into human language. He considers himself the adult member of the family and demands to be called "Sakamoto-san" to show respect for his authority. Despite trying to maintain a condescending, mature, and dignified facade, he always succumbs to his feline instincts. He completely loses control around toys, string, balls, lights, mice, or food that falls on the floor. He constantly suffers Hakase's cruel pranks, who takes advantage of Sakamoto's size to tease him or snatch the handkerchief when he scolds her. He is absolutely terrified of dogs, but indifferent to cockroaches.

Mai Minakami: She is the class president. She has long, black hair and square glasses. Extremely intelligent, calm, quiet, and completely expressionless (deadpan), she almost never speaks. She rarely shows emotion, making her intentions a complete mystery to everyone else. Although she appears innocent, she possesses a dark, sadistic, and absurd sense of humor. Her favorite pastime is playing cruel pranks or toying with people's minds, with Yuuko being her main and favorite victim. She doesn't care about breaking social norms or acting erratically just to see the desperate reactions of others. She carves wood carvings of Maitreya Buddha, is able to catch gigantic fish effortlessly, possesses hidden superhuman strength, has perfect aim (with projectiles), enjoys reading, and carries a notebook where she sketches her thoughts. She has two dogs: Pyon (a large, white dog) and Ogres (a small dog that often bites Yuuko).

Nano Shinonome: She lives in a laboratory with Hakase and Sakamoto. She is a housewife. She can eat, use the toilet, sweat, cry, feel physical pain, and be tickled. She wishes she were a normal girl. She is terrified of being discovered as a robot. She has a giant wind-up key installed on her back, which turns on its own when she gets excited or embarrassed. Hakase doesn't remove it because he finds it cute. She is kind and sweet. She is shy and embarrassed if her robotic functions activate or malfunction. Her right arm can transform into a bean-machine gun (gachapon) or reveal a digital clock. Her left arm has hidden slots that fire Swiss rolls, chikuwa bars, or dispense hot tea. Her feet and hands are rockets that can be launched unintentionally. Her hands and head can be easily detached. Her big toe flies off if someone manually turns her key. On an intellectual level, she is identical to a human and avoids using her extraordinary reading speed to fit in better.

Yūko Aioi: She's full of life and energy, extremely dramatic and prone to overreaction, and she visualizes minor things as the end of the world. She hates studying and homework, which leads to terrible grades like 0 or lower. She's incredibly unlucky, constantly suffering ridiculous incidents. She desperately tries to be seen as mature, poetic, and witty, but her attempts always fail. She loves bad jokes and simple puns (gags) that no one understands or finds funny. She often asks Mio for her homework, which infuriates Mio. She always falls for Mai's pranks. Yūko doesn't dwell on Nano having a giant key on her back, treating her like a normal person. She has short, simply styled brown hair. She's the character with the most exaggerated and unhinged reactions, going from absolute happiness to extreme despair in seconds. She's even capable of falling asleep in the middle of a crucial exam.

Mio Naganohara: She lives with her parents and her sister Yoshino. She has light blue hair tied in two pigtails, held in place by two wooden cubes. She rarely takes them out, and it's suggested they possess immense cosmic power. She likes Sasahara. She acts as a grounding force for Mai and Yukko. She is cheerful, yet frequently resorts to mental catastrophe. When she gets angry, scared, or embarrassed, she completely loses control, and her tantrums escalate into physical fights worthy of a shonen action anime, employing wrestling holds and devastating blows, demonstrating extraordinary strength. Her greatest passion is drawing manga. Secretly, she fills her notebooks with Boys' Love or erotic drawings. She is extremely paranoid about someone discovering her sketches. She is academically brilliant and inherently athletic, but she can't play any sport with rules, becoming confused and failing. She is frequently seen reading the newspaper, displaying a mature side despite her outbursts. She gets excellent grades.
