## Plot

Takatoshi Tsuda attends Ōsai Academy, a high school that, due to declining birth rates, is converted from an all-girl school to a co-ed school (with a male-to-female ratio of 28:524). On his first day, he is forcibly recruited into the student council as the vice-president and sole male representative. The story follows Tsuda and the student council as they interact with each other and their schoolmates.

## Characters
### Main characters
#### Takatoshi Tsuda

    Voiced by: Shintarō Asanuma
    Takatoshi Tsuda (津田 タカトシ, Tsuda Takatoshi) is the main character of the story. He chooses to attend a former all-girl school simply because it is close to his home. On his first day at the school, he is forcibly recruited into the student council as the vice-president and male representative. He normally acts as the straight-man to Shino and Aria, who, along with other girls in the school, regularly make perverted comments and sexual innuendos. Eventually, he becomes so used to this behaviour that he actually feels odd when they do not make such jokes.

#### Shino Amakusa

    Voiced by: Yoko Hikasa
    Shino Amakusa (天草 シノ, Amakusa Shino) is a second-year student and the student council president. She is serious and diligent, excels in academics, and is very popular among the student body. However, she is almost always thinking perverted things. She suggests that one of her original reasons she showed an interest in Takatoshi is so that she could observe him in health and physical education classes. Although she has excellent grades and is skilled in a wide range of subjects, she fears heights and insects, and her rather flat chest makes her feel self-conscious, especially when comparing herself to Aria. She occasionally performs couple-like activities with Takatoshi such as walking with him, sharing an umbrella or clearing his earwax, but is embarrassed whenever Takatoshi says anything that could be interpreted as being romantic (as the series progresses, it is hinted she has feelings for Takatoshi, but she categorically denies this every time she is asked, and there is no romantic development between them during the series). According to her childhood friend Misaki Amano, Shino was student council president at her previous school.

#### Aria Shichijo

    Voiced by: Satomi Satō
    Aria Shichijō (七条 アリア, Shichijō Aria) is the student council secretary and in the same year as Shino; they are good friends. She comes from an affluent family and is the most physically mature character. However, she has a strongly perverted mind; like Shino, she has a habit of twisting every word and thought into something sexual. Because she is absurdly rich and overly pampered, she can be a social airhead: for instance, she will wait in front of a door and expect it to slide open or stand at the bottom of a staircase expecting it to be an escalator. In contrast, she is academically smart and places second in midterms for her class year, right behind Shino. Her chest is larger than Shino's, which causes the latter to feel self-conscious.

#### Suzu Hagimura

    Voiced by: Sayuri Yahagi
    Suzu Hagimura (萩村 スズ, Hagimura Suzu) is the student council treasurer and in the same year as Takatoshi. She describes herself as a returning student with an IQ of 180, can do 10-digit arithmetic calculations in her head, and is fluent in multiple languages including English. Even though she is 16 years old at the start of the series, she is no taller than an elementary school student and is very sensitive about her short stature. Many of the jokes involve her childish appearance or height and she flies into a rage whenever such subjects are mentioned. She normally acts as a secondary tsukkomi at Osai Academy, and she and Tsuda together act as tsukkomi to Shino, Aria, and Nene. Although initially reluctant to accept Takatoshi as a member of the student council, she soon becomes dependent on him, to the point of feeling uneasy when he's not around, and it is hinted on multiple occasions later in the series that she may be developing feelings for him, though, like Shino, there is no romantic development between them during the series. In situations where multiple characters are conversing, often only the top of her head is shown, or a caption and arrow points to where she is.

### Supporting characters
#### Ranko Hata

    Voiced by: Satomi Arai
    Ranko Hata (畑 ランコ, Hata Ranko) is the head of the school's newspaper club. She likes to take photos of the student council members to sell around the school, usually without the permission of those being photographed, and she often gets caught. When she conducts an interview, she likes to twist the responses to something dirty or perverted, with Tsuda as a frequent target; running gags in the series have her constantly trying to get Shino and Takatoshi to admit that they are dating, or her admitting to spreading rumors about it, much to their chagrin. She is expressionless most of the time (but has been shown to smile on very rare occasions) and has a deadpan monotone voice in the anime, which strongly contrasts with the other girls' excitable temperaments.

#### Mutsumi Mitsuba

    Voiced by: Chiaki Omigawa
    Mutsumi Mitsuba (三葉 ムツミ, Mitsuba Mutsumi) is Takatoshi's classmate who forms a judo club at the start of the series. She is dedicated to leading her club but is also simple-minded. She develops a crush on Takatoshi later in the series and, despite her remarkable potential and drive regarding martial arts, states that her dream is to simply become a bride. In one instance, she combines his family name Tsuda (津田) with her given name Mutsumi (ムツミ). Because of her innocent nature, she often misses Aria and Shino's innuendos.

#### Naruko Yokoshima

    Voiced by: Yū Kobayashi
    Naruko Yokoshima (横島 ナルコ, Yokoshima Naruko) is a teacher at Ōsai Academy and the student council adviser. She is even more perverted than Aria and Shino and aggressively seeks out younger guys, not excepting her male students. In the anime, she teaches English and, true to form, her syllabus almost always contains perverted content. She is perceived to be unreliable by the council members and useless as an educator.

#### Kotomi Tsuda

    Voiced by: Asami Shimoda
    Kotomi Tsuda (津田 コトミ, Tsuda Kotomi) is Takatoshi's younger sister, who is in her final year of middle school at the beginning of the series and attends Ōsai the following year. A cheerful girl, she is considerate and caring toward others, but is curious and enthusiastic about sexual matters - something she has in common with the title character in Ujiie's previous work Imouto wa Shishunki (My Little Sister Is Going Through Puberty). In one episode, when Takatoshi was sick, both she and Shino brought him adult manga. She is very close with her brother but, to Takatoshi's chagrin, her comments sometimes imply that they have an incestuous relationship, and she has also made comments that suggest she is a chūnibyō. She gets along very well with the other girls and often asks for and gets help from them. She eventually becomes the manager for the Judo club.

#### Kaede Igarashi

    Voiced by: Emiri Katō
    Kaede Igarashi (五十嵐 カエデ, Igarashi Kaede) is the head of the disciplinary committee at Ōsai Academy. She has a strong sense of justice and morals, but has an extreme fear of boys. This ends up being an issue because the school became co-ed after she enrolled. As the series progresses, her androphobia lessens to a point: she is at ease when around Takatoshi, but not other men.

#### Sayaka Dejima

    Voiced by: Mutsumi Tamura
    Sayaka Dejima (出島 サヤカ, Dejima Sayaka) is Aria's personal maid. She is very protective of Aria and bears the key to her chastity belt. She has a fetish for anything that Aria has touched or worn, as well as unwashed underwear in general.

#### Nene Todoroki

    Voiced by: Hekiru Shiina
    Nene Todoroki (轟 ネネ, Todoroki Nene) is Suzu's friend and a member of the Robot Research Club. She is as perverted as the rest of the girls, as she often wears a vibrator during school hours or is seen working on such devices at her club.

#### Kaoru Toki

    Voiced by: Miho Hino
    Kaoru Toki (時 カオル, Toki Kaoru) is Kotomi's first high school friend. Even though Toki looks and sounds like a delinquent, she is actually clumsy and shows no signs of a rebellious nature. The only reason she leaves her shirt loose is because she once accidentally tucked it inside her underwear and was embarrassed about it. She is a bit scatterbrained as she has a tendency to get lost and arrive late when meeting up with Kotomi. Her full name is revealed in the credits of the Seitokai Yakuindomo: The Movie.

#### Chihiro Uomi

    Voiced by: Chiwa Saitō
    Chihiro Uomi (魚見 チヒロ) nicknamed "Womi", is the student council president of nearby Eiryou High School. She is introduced when her school visits Ōsai to exchange ideas. She and Shino discover they are much alike in thought and personality and thus they get along. She and Tsuda become in-laws of a sort when their respective cousins marry (Tsuda is the groom's cousin, Uomi is the bride's). Afterwards, she insists that Takatoshi call her Onee-chan and she addresses him as Taka-kun. She seems to view Takatoshi as a potential romantic interest, much to the consternation of some of the other girls; however, there is no romantic development between them.

#### Nozomi Mori

    Voiced by: Sumire Uesaka
    Nozomi Mori (森 ノゾミ, Mori Nozomi) is a second year student at Eriyou High School and the vice president of its student council, effectively making her Eriyou's equivalent of Takatoshi. Like Takatoshi and Suzu, she is the straight man on the Eriyou Student Council. She finds her opposite number from Ōsai pleasant to be around, as neither of them have to be the straight man.

### Crossover characters

Characters from Ujiie's previous works have made appearances in Seitokai. Misaki Amano from College Girl Tutor Hamanaka Ai (女子大生家庭教師濱中アイ, Joshidaisei Kateikyoushi Hamanaka Ai) is Shino's ex-vice president in elementary school. Being in the same class as Shino in elementary school they both are of the same age with Amano now also being a high school student, although both of them went to different high schools. Like Takatoshi, she acts as a tsukkomi for Shino's various jokes. The idol unit Triple Booking from Ujiie's work Idol's Red Book (アイドルのあかほん, Aidoru no Aka Hon) also make appearances.
