    Fujisaki Girls Academy Student Council 

Kurahashi Riko
Voiced by: Rie Kugimiya (Drama CD) and Manami Numakura (Anime)

A second-year student at Fujisaki Girls Academy. Her tomboyish and rebellious personality made her one of the most popular students in the school, and her hanging out with boys in elementary school started rumors that she has had a very successful love life. After a chance meeting where she caught Maki kissing a body pillow in the Student Council office, she gets conscripted as the Council President's Assistant, and provides Maki with "expert opinions" for her Love Research. This is all despite the fact that she has never dated a single boy.

Maki Natsuo
Voiced by: Yui Horie (Drama CD) and Chinatsu Akasaki (Anime)

A second-year student at Fujisaki Girls Academy, and an unbelievably competent Student Council President, who is capable of taking up all the responsibilities of the entire Student Council by herself. However, her cool, competent demeanor quickly disappears when you realize that she's a huge Cloud Cuckoo Lander that is obsessed with an idealistic understanding of romance. She even has a body pillow with a caricature of her "ideal love interest" on it named "Huggy" (Dakkii in Japanese), which she uses to practice kissing.
  • Academic Athlete: Implied.
  • The Ace: She's a top-notch student at The Fujisaki Girls' Academy who has some incredibly good grades, charismatic people skills with the teachers and efficient human resource managing. Riko mentions that Maki is so impressive that she could do all of this at once at no penalty to her overall performance - in Riko's words, "a super middle schooler".
  • Amazingly Embarrassing Parents: Her dad runs a lingerie company, and appeared in a commercial extolling various womens' undergarments in song. She's very sensitive about it.
  • Attractive Bent-Gender: She can pull off a fairly convincing Bifauxnen, but "Makio" just ends up creeping everyone out more than anything.
  • Belligerent Sexual Tension: Between her and Yan.
  • Big Fancy House
  • Cloudcuckoolander: She pulls some really Insane Troll Logic out of nowhere in what should be ideal circumstances in a romantic encounter. This causes her otherwise normal behavior to turn eccentric, and turns off at least two of the guys at the cram school as a result.
  • Dude Magnet: Nearly every boy has shown attraction to her.
  • Even the Girls Want Her: Due to her intelligence, kindness and beauty. She gains the same reaction Riko gets from their fellow schoolmates.
  • First-Name Basis: When a boy uses her first name without honorifics (thinking it was her last name) she completely panics, acting like he stole her Sacred First Kiss, and falls into a Heroic B.S.O.D.. She had, of course, envisioned some insane romantic scenario in which a guy she'd been dating for months would finally use her first name without honorifics.
  • Girly Girl: She makes girly runs, is hopelessly romantic and fits the bill of a graceful young lady (that is, until Insane Troll Logic kicks in...).
  • Girly Run
  • Hair Color Dissonance: Appears to have blue hair, but characters describe it as gorgeously black.
  • Heterosexual Life-Partners: Becomes one with Riko.
  • Hypercompetent Sidekick: She was this to Yuiko, until Yuiko promptly resigned in disgust.
  • I Just Want to Have Friends: Prior to meeting Riko, she was largely self-reliant. Then when Riko greets her friend Mika in the hallway, Maki has a sad look on her face at seeing how friendly the two girls are. Later on, after she finds out that Riko lied about being an expert on love, she was more distressed at the fact that Riko wanted to quit the student council and probably not spend any more time with her, than the fact that she lied. At least until the latter gave a heartfelt apology, stated she didn't want to quit, and declared them to be best friends.
  • In-Series Nickname: "Fuji's Princess"
  • Insane Troll Logic: Owing to her Cloud Cuckoo Lander status, Maki's wacky conclusions in supposedly perfect courting situations lead to some very fatal errors, such as exaggerating the melodrama of a young relationship situation between two lovers, dislocating Riko's fingers in a practice of holding hands, simulating Crash-Into Hello at break-neck speed, and improving one's attractiveness by exposing one's nape rather than making an Expository Hairstyle Change.
  • Lonely Rich Kid: Although she doesn't flaunt her riches, her father is a successful, if somewhat embarrassing, businessman, and kept her away from boys her age. This may help explain why Maki has such weird ideas about guys in the first place, particularly after her sister accidentally reads some of her love lab notes and convinces him to loosen his grip on her upbringing a little, lest some smooth talking playboy exploits her naiveness.
  • Long Hair Is Feminine: It's a part of her Girly Girl charm.
  • Love Freak: To a fault by way of Insane Troll Logic.
  • Ojou
  • Parody Sue: As a Cloud Cuckoo Lander Ace Student, she's overly competent in all academic issues, but is exaggeratedly terrible at her love life.
  • Sacred First Kiss: A common gag is Yan stealing her "first times" on many occasions, much to her chagrin, since her simulated romantic scenarios are ruined every time. These include the first time she was called by her first name, the first time she was in picture with a boy, the first time she was saved from an accident, etc.
  • Stop Copying Me: Riko tries to copy her actions to be more "girly" upon learning her nickname ("The Wild One"), and everyone is either disturbed by her change in character, or completely disgusted. Maki counters by dressing as Makio, something Riko would never willingly do.
  • Student Council President: In effect, to the extent that most students think she's the president, but technically she's the vice-president.
  • Sweet Polly Oliver: Riko jokes that it'd be easier to study if a hot guy was encouraging Maki dresses up as one.
  • Terrible Artist: Her body pillow has a crude caricature of a male student on it, in stark contrast to the more conventional Bishounen or Hunk. For the sake of Rule of Funny, her romance fantasies involve meeting a living version of her absurd artwork.
    • She's honestly confused and can't understand why the art teacher gave her a "D" for her drawings (of student council members).
  • Thinks Like a Romance Novel: She brings up things like Meet Cute moments, only to screw 'em up with Insane Troll Logic.

Tanahashi "Suzu" Suzune
Voiced by: Ryoko Shintani (Drama CD) and Inori Minase (Anime)

A diminutive first year student at Fujisaki Girls Academy, a huge Shrinking Violet, and the Student Council's secretary. She joins in on the Student Council's Love Research after some convincing from Riko, and laughing at Riko and Maki's Straight Man and Wise Guy routine.

Enomoto "Eno" Yuiko
Voiced by: Ryo Hirohashi (Drama CD) and Ayane Sakura (Anime)

A wealthy third-year student at Fujisaki Girls Academy, and former Student Council President. She angrily left the student council when her Hypercompetent Vice President, Maki, took all her work from her. After coming to blows with Riko and Maki over the position of President, she re-joins the Student Council as Vice President.

Mizushima "Sayo" Sayori
Voiced by: Akeno Watanabe (Drama CD) and Taichi You (Anime)

A bespectacled third-year student at Fujisaki Girls Academy, former Student Council Treasurer, and Yuiko's lifelong friend. She's well-known for being a miser who has a weird fascination with money, and has openly stated that she only became treasurer so she could handle the funds distributed to the various clubs. Before the series started, Maki dismissed her because this behavior creeped her out, but she returns to her original position when Enomoto becomes Vice President.
  • Aloof Dark-Haired Girl
  • Affectionate Nickname: Gets called "Sayo" by Yuiko.
  • Blind Without 'Em: She actually tripped on her own feet after the girls take her glasses away briefly to change her look for a date.
  • Brutal Honesty: She often says it like she sees it, which doesn't go over well with Riko a lot of times.

  • Deadpan Snarker
  • The Gadfly: In the early parts of the manga, she would tease Riko about her romantic experience in the hopes of getting her tell the truth. She continues doing it with Riko's obvious crush on Nagi.
  • Gamer Chick
  • Girlfriend in Canada: Supposedly has a boyfriend, whom she hasn't seen in person since their relationship began. Subverted; he does exist.
  • Greed: In the form of Money Fetish, no less.
  • Jerk with a Heart of Gold: As much of a Jerk Ass she can be at times, she does have moments where she's nice and does things without an ulterior motive, such as when Maki's love lab notes were accidentally distributed at a student council meeting. Sayo claims that said notes were research for a question given to them anonymously by a student, and they all accept that excuse, since they're unaware of Maki's Cloud Cuckoo Lander tendencies.
  • Meganekko
  • Mistaken for Cheating: When she went to return Haru's uniform for Yuiko who got sick, her boyfriend just happened to see it.
  • Money Fetish: She openly admits to Yuiko that it's money she likes, not the accounting work that comes with the treasurer position and worse, obsessed with controlling the fundings of people she can manipulate.
  • Only Sane Woman: In the sense that she's the only one in the student council who doesn't fall for Riko's lie.
  • Riches to Rags: She was transferred out from Fujisaki Academy to a public school when she was in her fourth grade because her parent's business went under.
  • Scary Shiny Glasses: A large portion of the time.
  • Stealth Hi/Bye: Discussed by Maki when describing her.
  • Stoic Spectacles
  • Tsundere: An odd variant. She states the reason she doesn't like meeting her boyfriend is because he throws her off. But at the same time, its made clear that she wants to keep him.
  • Voice Changeling: She has so far been able to copy Maki, Suzu and Nagi's voices.
  • When She Smiles: Has only two known instances of actual happy laughter, both of them heart-melting; especially to Yuiko.
  • Wingding Eyes: Displays yen symbols in her eyes in at least one scene.

    Minami Middle School’s Student 

Nagino Satoshi
Riko's childhood friend and former football teammate. He goes to the same cram school as Yan and Mika.
  • Adorkable: A lot of girls think so because of his kind personality and his tendency to get flustered a lot.
  • Belligerent Sexual Tension: Minor example between him and Riko. While they do argue a lot, it's more like good natured ribbing between friends.
  • Berserk Button: Don't call him cute.
  • Bishōnen: He is often thought as cute by the girls.
  • Book Dumb: On par with Riko.
  • Chick Magnet: Riko, Mika and two unnamed girls that find him attractive.
  • Childhood Friend Romance: Satoshi and Riko were somewhat close when they were younger, and later on he admits to Maki that he did have a crush on Riko. Whether that was a lie to cover for Riko, or a truth, considering he did run away after hearing Riko rejected him, is uncertain.
  • Crazy Jealous Guy: He did not like hearing that Riko spent a night with a boy(it was Maki crossdressed but Nagi didn't know)
  • Dude Looks Like a Lady: In his childhood.
  • Informed Attractiveness: Nagi gets it the most out of the boys with the main cast calling him cute and Mika even saying he was her type.
  • Nice Guy: He usually friendly and has willingly let his social status take a hit to help Riko. Also one of the few boys that treats Maki with respect.
  • Oblivious to Love
  • One of the Boys: Gender Inverted, Riko stated she treated him as a girl due to his appearance when they were young. Some flashbacks show that even after growing up he still hasn't fully overcome this.
  • She Is All Grown Up: Gender Inverted, even Riko couldn't recognize him at first.
  • She Is Not My Girlfriend: Trying to ask Nagi about how or why he confessed to Riko usually sends him into a blind rage.
  • Tsundere: Type B, he's nice and polite to everyone but Riko pushes his buttons.
  • Those Two Guys: For a while he would always appear with Yan, this started to lessen when he and Yan got more screentime.
  • Warts and All: What made Riko finally admit that she liked him, was him telling her that he loved her personality.

Ikezawa Masaomi/Yan
The Vice-President of Minami Middle School's Student Council. He goes to the same cram school as Nagi and Mika.
  • The Ace: Every bit as good as Maki.
  • Anti-Hero: Crude, mean, aggressive but he is one of the few boys that treat Maki as a person and not as a piece of meat and will help her out if needed.
  • Cannot Spit It Out: He refuses to admit that he has any interest in Maki either as a person or her work on the student council.
  • Deadpan Snarker: Much like Sayori, he often tells it like he sees it.
  • Defrosting Ice King: In the past he was even more cold and started to calm down when he started tutoring Riko. As the series goes on, he starts defrosting more due to Maki.
  • Final Boss: The other characters regularly compare him to the final boss of a video game.
  • Hypercompetent Sidekick: Like Maki, he's this to Haru.
  • In-Series Nickname: "Yan"
  • Jerk with a Heart of Gold: He can be pretty mean at times and will mock people as he likes. But he does give credit where credit is due and willingly tutored Riko and Nagi.
  • Loves My Alter Ego: Well not love, he doesn't know that Maki is the student council president and has stated on many occasions that he deeply respects Fujisaki's student council president. On the other hand he sees Maki as a weirdo. He does not take it well when he finds out they're one in the same
  • Megane
  • Mistaken Nationality
  • Only Known by Their Nickname: Everyone called him Yan, Riko doesn't even remember his real name at first.
  • Paper Fan of Doom: Receives one from Maki, Suzu's handmade.
  • Smart People Wear Glasses: Incidentally, he was also the one who was forced to tutor Riko so that she could attend Fujisaki, which seems to have high academic requirements. When he tells Maki about it, he seems really resentful about it however.
