Main characters

    Nozomu "Baka" Tanaka 

Nozomu "Baka" Tanaka
The One of a Kind Problem Child
Voiced by: Chinatsu Akasaki

Tanaka is a physically plain, but notoriously stupid and grating girl who completely lacks awareness of her faults. She's a childhood friend of Akane and Saginomiya.

  • Actor Allusion: This isn't the first time Chinatsu Akasaki voiced a simple-minded fool compared to the rest of the cast.
  • A-Cup Angst: Implied. When Ota opines that chest hair is redundant as cushion for the torso, since girls already have breasts for that, Baka reacts with a screaming fit.
    Tanaka: Some women don't have any goddamn cushions on them, right? *thrusts chest forward* RIGHT HERE!!!"
  • Adaptational Attractiveness: Played with. Due to the artistic direction of the anime, she is depicted as considerably more attractive than in the manga, where she is more plain. However, in-story, she is still treated as below-average in the anime.
  • Adaptational Nice Guy: For a given value of "nice". Baka's anime counterpart is a lot less rude, crude, crass, and foul-mouthed compared to her manga version, where she drops expletives on a per-word basis.
  • Affectionate Nickname: Hime refers to her as Non-chan senpai.
  • Book Dumb: Has absolutely no aptitude in studying. Waseda has to keep her for remedials for the first day of school because of this.
  • Brutal Honesty: She hammers down on Hime's dad's Ramen so mercilessly that in anger, he decides to try to improve his ramen, improving his self-esteem and his culinary capabilities. This ends up cementing his drive as a restauranteur, opting to move away to build his food a better reputation. This touches Hime so much that she strives to improve herself in any way she can.
    Tanaka, before putting the older Nakamura's ramen in her mouth: Wow, this is the first time I've had ramen so shitty I didn't need to eat it to know.
  • Butt-Monkey: She's the receiver of some extremely savage passive-aggressive lashings by both Ota and Robo which would emotionally destroy any other girl that is not nearly as dumb as her.
  • Catchphrase: "Hey, do you want to hear something amazing?". Usually followed by something very lame or nonsensical.
  • Chaotic Stupid: She's dumb enough that she appears to be completely insensitive to any rules whatsoever.
  • Charles Atlas Superpower:
    • Baka has an inexplicable ability to adhere herself extremely strongly to the ground underneath her when throwing a tantrum, such that Ota and Robo can't get her to budge even an inch no matter what they try, up to and including using a mop as a lever and a janitor as a fulcrum.
    • In the very next episode, she also displays the ability to very precisely chomp off all of the uncoated parts of an entire Bocky pack in a single swipe. Real Pocky sticks are very fragile and easy to break, so snapping off this part of one stick alone is much harder than it seems without careful calculation, much less an entire pack while said pack is still in the box and being held by someone else.
  • The Dreaded: For Loli, who's usually the number one victim in all of Baka's antics. Baka is also the one who patronizes and picks at her height complex the most. Every time she sees Tanaka, she recoils and guards.
  • The Friend Nobody Likes: She elicits this from even her close friends Ota and Robo, who don't particularly like her, and eventually extends to most of her other classmates. She's a royal pain in the ass to most of the people that meet her.
  • From Bad to Worse: As detailed in Spanner in the Works, Tanaka tends to make everything less tolerable just by being there.
  • Genki Girl: One of the most unbridled and energetic of the main trio, though not in a cute way.
  • Hidden Depths:
    • Her stupid ramblings are surprisingly detailed and well thought-out, and could pass off as somewhat intelligent rather than flights of fancy if they didn't come from her. Said stupid ramblings do work for the better once in a blue moon, though, as she was able to deliver a profound act of kindness towards Hime and her father without ever noticing that she did it in the first place.
    • Both Akane and Saginomiya consider her among their closest friends, and Akane initially thinks that she hanged out with Tanaka to feel better about herself, only to realize that this is certainly not true. That she's a pain in the ass doesn't mean that she isn't loved.
  • Idiots Cannot Catch Colds: In the anime, she is shown consuming expired bread so old and moldy that it turned into every color of the rainbow, without ever showing any problems afterwards.
  • Innocently Insensitive: Baka is this, believe it or not. She's not actually malicious, even though her actions may suggest otherwise. She likes to crack jokes or engage in (what she thinks are) fun activities, but due to her lacking sense of tact and intelligence, she's often unable to see just how much of a pain in the neck she's becoming to any given person. Most of the time, her (unwittingly) preferred targets are Loli and her small size.
  • In-Series Nickname: "Baka", for being Chaotic Stupid.
  • Irony: She entered high school in order to meet boys, but it turns out that the person that thinks about her the most in that way is Hime, a girl she met when she was in middle school.
  • It's All About Me: A non-malicious example. Tanaka proceeds almost exclusively for her own amusement and out of sheer boredom, but she's not smart or aware enough to notice that she's doing something wrong. Akane and Saginomiya barely bother to correct her or indulge her in her diatribes because they know that it's an exercise in futility.
  • Living Emotional Crutch: For Hime, as she unwittingly became the cornerstone of her transformation from pudgy elementary school kid to posh and coiffed high school student. Hime became the princess she always wanted to be because of Tanaka.
  • Moment Killer:
    • Often does this, because of her strange thought process.
    • Hime laments that most of their first encounter after being apart for so long consisted of dirty jokes instead of a more profound conversation, but she is still glad that she was able to have Tanaka back in her life.
  • Nice, Mean, and In-Between: Baka fits the Mean archetype, though she's not actually malicious (see Innocently Insensitive above).
  • The Nicknamer: She gives the entire class nicknames on the first day of school, and they stick.
  • The Pollyanna: A hilarious subversion. She's almost immune to insults because she is not intelligent enough to get offended by anyone's abuse, which she takes in a stride because she cannot process it to begin with. She's usually undaunted and obnoxiously animated all the time, though not in a cute way like a Genki Girl.
  • Pun: This is one of a handful of things that Baka consider to be real humor, though Ota and Robo find her puns to be incredibly lame and predictable.
  • Sir Swears-a-Lot: At least in the manga where she lets every single swear word fly with abandon likely to highlight her rough, unfeminine nature. She herself is aware of this saying that every other word she says is "shit".
  • Spanner in the Works: For everyone she meets. Whenever she intervenes in whatever anyone's doing, the original intention is wasted, and everyone is left at best miffed and at worst disgusted at the whole situation.
  • Thinks Like a Romance Novel: She comes up with extremely off-the-wall scenarios where she conquers boys and men, which show her complete lack of experience with the opposite sex. Every interaction ends up with the man uttering the same phrase about her:
    -What an interesting woman!
  • Toilet Humour: A surprisingly big portion of the gags related to Tanaka come from this, which is notable coming from a girl. In this respect, she's two hairs short of being One of the Guys.
  • Weirder Than Usual: When she's infected by a strange protozoa in chapter 72 of the manga, Baka starts acting much nicer and more considerate than usual, becoming something of a Nice Girl and diligent (if still not particularly bright) student overnight. This Out of Character moment weirded everyone out, though apparently not in an entirely bad way as Ota seems to like her in this state than her normal self. It doesn't stick, however, as she returns to normal after several hours of violent diarrhoea.
  • With Friends Like These...: Albeit she's a nuisance for most people that meet her, Tanaka is a particularly deficient friend towards Loli, as she regularly convinces her of outrageous stuff that her classmates have to correct later. She doesn't proceed out of malice, however, as she's not intelligent enough to do something like that out of her own volition. She's just ignorant and neglectful.

    Akane "Ota" Kikuchi 

Akane "Ota" Kikuchi
The Two Timing Aspiring Mangaka
Voiced by: Haruka Tomatsu

Akane is a serious and even-headed girl who is an otaku and an amateur mangaka with closet-fujoshi tendencies. She's a childhood friend to Tanaka and Saginomiya.

  • A-Cup Angst: When Lily makes her introduction to the class, Ota fixates on her ample chest in annoyance.
    Akane: What is this disparity in society?
    • Which is ironic considering this image shows she has a bigger bust than Lily.
  • Adaptational Attractiveness: Not to a physical level like Baka, considering that she's already one of the better looking characters in the manga, but Ota too has seen major improvements to her wardrobe and fashion when adapted into the anime. For starters, she wears much more fancy clothing and makeup compared to the same scenes in the manga, most notably the part where she finally met Teishotoku-P for the first time; whereas in the manga, Ota only wears a simple no-frills dress, the anime gives her much nicer clothing and even an expensive-looking coat (though considering that part was bumped up from summer to near-Christmas, she probably needed it). There's also what's mentioned in the Ms. Fanservice entry below.
  • Art Shift: If Ota spots a prospective male pairing, her character art would become extremely simplified to the point Loli couldn't recognize her. That is before her eyes start morphing as well, and she even has a special name for this "mode".
    Akane: B&L EYES!!!!!
  • Closet Geek: Downplayed. While Ota doesn't have a problem with people knowing about her Otaku lifestyle, she is quite secretive about her fujoshi nature. Not that it stops Robo, Baka, and Loli from knowing about it, since she wears it on her face.
  • Fangirl: Of Boys' Love and of Teishotoku-P's music.
  • The Fashionista: She dresses rather well outside of school, as well as sporting different hairstyles with each appearance in her casuals. She even dyes her hair to a lighter tone after moving to high school.
  • Gamer Chick: While Ota is never seen actually playing anything, she has a quite venerable stockpile of consoles and other peripherals in her room. The short list of these include a Nintendo Wii, a PlayStation Vita, what looks to be a PlayStation 4, and a nondescript VR headset, assuming she doesn't play games on her PC as well. The brief glimpses of her room also occasionally show what appears to be a Musou game, likely a Dynasty Warriors Expy, currently paused on her TV, with quite impressive combo counts, suggesting Ota isn't half bad at hack-and-slash.
  • Heroic BSoD: After finding out that Teishotoku-P is actually Waseda.
  • Hidden Buxom: Despite her jealousy of Lily's figure, Ota is actually quite endowed herself.
  • In-Series Nickname: "Ota", for being an otaku.
  • Ms. Fanservice: In the anime. She's given a considerable focus while she's alone rummaging in her room wearing light jammies, showing that she's indeed a very attractive and shapely girl.
  • Nice, Mean, and In-Between: For a given value of "Nice", Ota is arguably the most personable and sociable of the three, and doesn't go out of her way to hinder or annoy anybody.
  • Only Sane Man: Compared to Nozomu's wackiness and Saginomiya's rather detached personality, she's the most grounded of the main trio.
  • Open Secret: Though everyone at class is aware of her otaku tendencies, she tries to hide her fujoshi side, albeit very unsuccessfully due to the fact that it reaches dog-in-heat levels from her whenever even a mere hint of yaoi is in the air.
  • Otaku: She wants to be a Sequential Artist when she was in elementary school, and on the first scene of the anime her room is seen to be rather stereotypical of one, including shelves of manga and is otherwise full of anime merchandise. This even extends to her romantic life; she has a crush on the Vocaloid producer "Teishotoku-P", who turns out to be Waseda.
  • Platonic Declaration of Love: She tells Teishotoku-P that she loves him for the music he produces and the positive influence it has had in her life, and later after finding out that he's Waseda (and after some dejected tears), she admits to herself that she loves him regardless of who he is because his music means the world to her.
  • Sir Swears-a-Lot: Next to Baka she has probably the foulest mouth of the main cast.
  • Spell My Name with an "S": Not her actual name, but her moniker. Sentai Filmworks, for example, uses both "Ota" and "Wota", an old reading of the same word.
  • Terrible Artist: Despite her ambitions, Ota's artistic capabilities are..."lacking", to say the least. She has a very loose grasp on the rules of perspective and anatomy, so her characters often end up with weird poses and body proportions, superimposed onto backgrounds that are Not Drawn to Scale. The only advantage she has gained since grade school is that her art is somewhat more consolidated and there's been progress, but nothing to call home about.
  • Tsundere: Towards anything related to Waseda, after he's been revealed to be Teishotoku-P, either during interaction or when he's brought up by her friends. When Baka noted the resemblance between him and a love interest in an otome game Ota is playing, the latter does a Spit Take so epic it launches the sausage in her hotdog directly into Baka's forehead and leaving a bruise, before hastily deflecting the point. Robo is not convinced.
  • Yaoi Fangirl: While she draws shoujo manga, she becomes giddy on interactions between men to the point that she'd look as if she was Off-Model.

    Shiori "Robo" Saginomiya 

Shiori "Robo" Saginomiya
The Emotionless Genius Girl
Voiced by: Aki Toyosaki

Saginomiya is a notoriously deadpan and expressionless girl with an interest on microbiology and the STEM field at large. She's a childhood friend to Tanaka and Akane.

  • The Ace: Saginomiya is the top student at her grade, being implied to be a Teen Genius since middle school, and it's stated that she enrolled in a mediocre school like Sainotama much in spite of her academic excellence in order to be with Akane and Tanaka. It's also implied that given the circumstance, it wouldn't take her that much effort to switch schools whenever she'd feel like it.
  • Berserk Button:
    • Making important decisions for her without consulting her first.
    • Messing with her cultured bacterium.
  • Big Fancy House: According to Ota in Chapter 36, she lives in one. However, she appears to live on a monthly "salary", which may not be that much.
  • Black Bead Eyes: Crosses with Dull Eyes of Unhappiness. Robo's eyes are drawn as these the most in the manga. Even during scenes where the panel is focusing directly on her face, her eyes are still drawn as little more than black dots for pupils with rudimentary eyelashes, and no shine whatsoever. They get better in the anime, though.
  • Charles Atlas Superpower: Episode 12 of the anime has Robo roll back up onto her feet while still in a standing pose as if she's a daruma, after being pushed down by Ota and Baka.
  • Deadpan Snarker: She is so deadpan that she borders on being altogether aphasic.
  • Emotionless Girl: She's always seen without much affect nor emotions, and this is why her nickname is "Robo".
  • The Gadfly: She seems to take enjoyment from making fun of her classmates, such as making Yamai think that she's a Robot Girl indeed when she follows her to the bathroom and sits in the stall next to hers.
  • Hammerspace: The eyecatch of Episode 1 shows Robo with a spring-loaded sucker punch fist hidden inside her shirt. How on earth does she hide it from view without it bulging out of her chest is another matter entirely.
  • The Heart: Despite appearances, Robo is an important cornerstone of the trio, often being the voice of reason for when Baka and Ota had a falling out to help them reconcile with each other. Being the only one capable of talking sense into Baka says a lot about how much she cares for and understands her friends.
  • Heavy Sleeper: It's implied that Robo sleeps for very extended periods of time. One panel in chapter 4 reveals how she once slept all the way from Friday to Monday, not waking up even once, and chapter 15 has her falling asleep on the train home and ended up riding all the way out to the countryside.
  • Hidden Depths: It's implied that she cares more about both Akane and Tanaka than she shows, as Majime states that she chose to attend their school to be with them, and even in the second year, she chose the liberal arts over the sciences to be able to be with her friends, both instances in spite of her personal preference for science and her high intelligence.
  • Identical Stranger: To a step sister of Aoyama, a friend of Takahashi's. Incidentally, both girls are also enrolled into Sainotama. This created a moment of awkwardness when Takahashi struggled to decide what to do, now that his love interest is very possibly part of his friend's new family, though thankfully the misunderstanding only took a couple of pages to solve. Robo isn't amused.
  • In-Series Nickname: "Robo", due to her Emotionless Girl traits being rather robotic.
  • Intelligence = Isolation: Defied. She joined Sainotama, a Dustbin School, just to be together with Baka and Ota. When she was studying middle school, she had no friends since people can't even guess what she thinks.
  • Mad Scientist: More in the Cloud Cuckoo Lander side of things, Robo wants to be a microbiologist, and routinely has containers with marine algae and Petri dishes with bacteria readily available. She has her own lab at home according to the anime.
  • My Way or the Highway: She states that it's not worth it for her being in Sainotama High if Tanaka isn't there, as it's one of the main reasons she attends such a subpar school in spite of her high intelligence (the other reason being, of course, Akane). She cannot bear the thought of being deprived of her best friends. That's how much she loves them.
  • Nice, Mean, and In-Between: Robo is the "In-Between" character. She isn't as socially-inclined as Ota, but at the same time she frowns at Baka's antics, even though the latter could be Actually Pretty Funny.
  • Noodle Implements: Robo is almost always seen fiddling with things that have little to no relation to the situation at hand, usually in the background while Ota and Baka are talking.
  • Omnidisciplinary Scientist: While she mainly sees herself as a microbiologist, she's certainly adept in molecular genetics in general if she's serious when she talks about gene editing. On the non-biology side, let's say in Chapter 45, she's been able to finish making a simple mobile game on a tablet during the span of one morning.
  • Rubik's Cube International Genius Symbol: She's sometimes seen playing one, which fits her Teen Genius nature. However, we never sees her solving it.
  • Slasher Smile: Robo rarely ever smiles, but when she does it's rather unsettling if Ota is to be believed.
    Akane: I haven't seen Robo smile like that in a long time.
  • Take Over the World: Played for laughs. After extracting the parasite causing Baka to be Out of Character in chapter 72 of the manga, Robo contemplates modifying it to dominate the human race by Mind Manipulation.
  • Teen Genius: The fact that she may have been among the national top ten in middle school breathes of this trope. Funny Background Event further indicates she is somewhat of an Omnidisciplinary Scientist as well.

    Saku "Loli" Momoi 

Saku "Loli" Momoi
The Rebellious Good Girl
Voiced by: Maria Naganawa

Saku is a diminutive and childish girl who has a complex about her size, compensating for it with aggressiveness unsuccessfully due to her innate niceness and innocence.

  • A-Cup Angst: Subverted for a moment, as Lily judges her to be a B-cup and not completely flat, which greatly boosted her confidence. That being said, she went overboard and forgoes Lily's other advice to avoid strapless bras as it has nothing to grip on, causing her considerable embarrassment when it drops, as she has body issues to begin with due to her size. Loli still has more up there than Baka, who is basically vertical.
  • Berserk Button:
    • Any reminders of her being Older Than They Look.
    • Don't distract her or try to play with her in class.
  • Book Dumb: While she doesn't appear to be any dumb and has a good work ethic, she is this. An extra material comic shows her chemistry quiz results: 42%, and couldn't do much beyond memorizing the periodic table.
  • Bowdlerize: In-universe. While Loli does regularly swear when not at home, her vocabulary consists of very family-friendly phrases that sound like those used by a child who's just learned how to cuss without knowing the words. Which she is.
  • Bratty Half-Pint: Downplayed. She is a Nice Girl by nature, but puts up a tough sassy front so that others do not treat her as a child due to her diminutive height. Naturally, this charade is pretty useless in the face of everyone in her class.
  • Children Are Innocent: She is the sweetest, most innocent girl in the manga, and fittingly, she's the universe's chew toy. Any talk of love, boys or sex usually goes over her head.
  • Comically Missing the Point: When she goes to watch the romantic movie that Lily recommended, Loli was more upset that the protagonists skipped school to elope, and that would be troublesome delinquent behavior, than getting the actual point of the film itself.
  • The Cutie: She's like a little doll. Fittingly to the trope, the most tender moments from the manga involve her relationship with her grandma.
  • Don't You Dare Pity Me!: Loli dislikes hand-me-downs and pitying favors that remind her of her height, so she's actually happy to have been put in the back row of class during her second year in spite of her difficulty seeing the chalkboard.
  • Embarrassing Nickname: For obvious reasons. The manga expands on this by showing her annoyance at Baka calling her that, but after everybody started addressing her that way, she quietly accepted it in resignation.
  • Hidden Depths: Loli sees the good in every person she meets and holds their words and actions at a very high standard, to the point that her classmates feel guilty about lying to her because she cannot fathom that anyone would do such a thing.
  • Hime Cut: She accidentally gave herself one trying to style her bangs, which in turn gave everyone else a laughing fit.
  • I Just Want to Have Friends: Albeit she tries to be aggressive, Loli is markedly susceptible to kindness and treasures every instance where she can become friends with her classmates.
  • The Ingenue: She is notoriously naive and childish, making her Embarrassing Nickname markedly fitting. She still believes in Santa Claus as a high school girl, and later Tanaka convinces her that babies are made when couples submit an application to the government. Because of her innocence over sex, there's an ongoing debate in the classroom regarding who will teach Loli sex education once and for all, and most of the girls tend to err on the side of caution when it comes to sexual topics around her (particularly Lily) because, as much as it's egregious that a 16 year-old doesn't know about the birds and the bees, they don't want to soil Loli's pureness of heart. The fact that she is so easily influenced makes her extremely vulnerable to their eyes, making her a manifest example of why she wouldn't fit the Incorruptible Pure Pureness trope.
  • Irony: Loli is as kind, gentle, cute and caring as a girl can get, which is the exact contrary of how she wants to portray herself. She just can't help it.
  • Japanese Delinquents: Played with in the most tender use of the trope. She tries to be one so that she isn't bullied for her size, but she's too much of a good girl and a sweetheart for the trope to be played straight.
  • Lady Swearsalot: In the most family-friendly way. Loli has a tendency to grumble on about the things that upset her, mostly Baka. Especially Baka.
    You dummy poopyhead!
  • Lovable Coward: She's a royal wimp when it comes to horror, and even passes out in the security of her own home after she watches one of Majo's favorite movies. Girl's just not built for that sort of thing...
  • Nice Girl: Loli is a girl who is fundamentally good, but Tanaka's dumb taunts usually bring out her crankiness instead.
  • Odd Friendship:
    • With Lily, who is a very extroverted person. This is due to the fact that Loli greatly admires her femininity and wants to become like her.
    • With Majo, who is a girl whose hobbies are on the opposite end of Loli's own. This is because, just like Loli, Majo is very sweet and innocent.
  • Older Than They Look: Because of her short stature, she is often mistaken by her peers to be a child, to her ire. Can't exactly blame them, since she seems to have barely grown at all since she was 8, if grandma's flashback in Episode 3 is to be believed.
  • Raised by Grandparents: By choice. Early in her life, she refused to abandon her grandma when her parents moved overseas. Her grandma is by far the most important person in her life, and she adores her to no end.
    My grandma is my pride and joy!
  • Serious Business: Not paying attention in class is a touchy subject to her, as Yamai comes to find out.
  • Sweet Tooth: She once tries to run errands to buy meat for hamburger steak so that her grandma cooks it for her, but ends up buying a case of confections instead.
  • Strong Family Resemblance: She is the spitting image of her grandma when she was her age, making her an Identical Grandson.
  • Token Mini-Moe: Due to her cuteness, Loli is the whole school's cinnamon bun. However, this is not something she particularly enjoys.
  • Undying Loyalty: To her grandma, whom she loves with all her heart. For Momoi, being called a "grandma's girl" is a tenet. The only reason she's studying at Sainotama is it's just a block away from here home, so she can see her grandma sooner.

    Minami "Yamai" Yamamoto 

Minami "Yamai" Yamamoto
The Severe Chuunibyou
Voiced by: Miyu Tomita

Yamai is a Chuuni who has delusions of grandeur and is academically procrastinating. She spends most of her time indulging in fantastical escapism, which affects her grades and her relationships with her classmates and teachers.

  • Attention Whore: Yamai loves being the center of attention. It's been speculated that her Chuunibyou nature is a side-effect of this, as she hams it up to get views and likes on social media.
  • Bad Liar: While she has a very active imagination, she's not a very convincing person altogether, which brings her a lot of trouble. She's so bad at it that even Majime can pick up on her lying, and Majime is Literal-Minded as all hell.
  • Bandaged Babe: She always wears copious amounts of bandages on her body and limbs at all times, even while sleeping, not because she's injured, but because she's, well, Yamai.
  • Bokukko: Yamai refers to herself using male pronouns.
  • Book Dumb: Just as bad as Tanaka, but unlike her, it's not because she's dumb, but rather procrastinating.
  • Cat Up a Tree: Played for laughs, despite her not being a cat. Yamai has a tendency to climb up tall trees to sit on their branches, and then get stuck up there.
  • Chuunibyou: The first time she's shown in the anime, she self-introduces herself in terminology not unlike a fantasy novel, and wears more like a video game character than a school girl. All while sitting on the school's observatory. Her nickname "Yamai" ("crazy") comes from the Cloudcuckoolander aspect of this trope.
  • Delinquent Hair: It's implied that Yamai dyed her hair blonde to suit her chuuni persona. In a setting where You Gotta Have Blue Hair is the norm, Waseda specifically points out how her hair color isn't natural.
  • The Dreaded: For Waseda, due to her unpredictable nature. At the very least, he somewhat knows what to expect from Tanaka, but Yamai has a special way to try his patience.
  • Food as Bribe: This seems to be one of Yamai's few weaknesses, as Waseda could usually resort to this to get her to snap out of her antics for a while and start listening to what he has to say.
  • Friendless Background: Yamai is the only girl in class who doesn't have particularly close bonds with any of her classmates, though she has expressed fondness for Loli, Majime and Lily, and shares a dumb camaradery with Tanaka. This is because her Chuuni makes her seek isolation.
  • Half-Human Hybrid: One of the more consistent things in her delusions is that she's a half-dragon.
  • Hero-Worshipper: She absolutely adores Shiikyon and greatly looks up to her due to Shiikyon's willingness to play along with her delusions. Her admiration is such that when Waseda brings Shiikyon in to ask about the damaged school statue Yamai basically acts like (and is drawn as) an excited puppy and readily admits to her that she damaged the statue with little prodding.
  • Hidden Depths: She appears to be interested and competent in physics, despite her general dislike of schoolwork.
  • His Own Worst Enemy: Yamai's Chuuni, combined with her poor planning, have put her in danger to herself and to her health. That is, not counting her grades...
  • Hypocritical Humor:
    • She considers Tanaka a complete idiot, in spite of not being that far off from it herself.
    • When having her her fantasy-ladden conversations with Waseda, she sometimes slips off from the Chuuni unintentionally because she forgets that she had previously assigned an outlandish explanation to something mundane, stating the latter. Waseda is always quick to point it out every time she does it.
  • In-Series Nickname: "Yamai", which means "sick". This may just mean she's "sick" from Eighth-Grade Syndrome, or Tanaka actually considers her "mentally ill". It's also a pun on her name (Yamamoto).
  • Mismatched Eyes: Unsuccessfully Invoked. Her eyes are actually of the same color, but Yamai tried wearing colored contacts in one chapter to create a heterochromic effect. It doesn't work, and she ends up hurting that eye quite badly, which gives her actual mismatched eyes for a while due to one being severely bloodshot.
  • Not So Different: She's as bad academically as Tanaka is, but she's considerably less thick-headed than her. Also, unlike Tanaka, she's aware that she's doing something wrong and detrimental to herself, but cannot help but engage in the Chuuni for her own indulgence.
  • Not So Stoic: Even someone like her can only take so much of Tanaka's stupidity, and is usually left befuddled whenever they interact.
  • Obfuscating Stupidity: Played with. Apart from using her Chuuni as a form of escapism, Yamai also tries to use it in order to distract people from pointing out her problems, and even though she tries to use it a lot, it never works for her because she's incapable of planning ahead and she's inconsistent with her own role-playing.
  • Obliviously Beautiful: Combined with Informed Attractiveness, Lily mentions that Yamai has a beautiful face, but that her overall behavior and quirks make people overlook her attributes.
  • Pointless Band-Aid: Played with. She has one on her right cheek, which is possibly part of her Chuunibyou package, but she often uses them to hide pimples.
  • Running Gag:
  • Sitcom Arch-Nemesis: Waseda, due to him trying to be a responsible teacher and her being, well, herself.
  • Situational Sociability: Yamai will completely drop the Chuuni if her parents are brought into the conversation. Even with her self-serving behavior, this shows that at the very least she has an instinct of self-preservation.
  • invokedWriting by the Seat of Your Pants: Yamai is actually pretty bad at being a Chuuni because she improvises her headcanon, which makes her stumble upon her own words when she forgets what she stated previously, constantly contradicting herself.

    Kanade "Majime" Ninomae 

Kanade "Majime" Ninomae
The Physically and Mentally Weak Honors Student
Voiced by: Rie Takahashi

Majime is a serious and even-headed tomboyish girl who is unwittingly popular in school. She has an obsession with Saginomiya, for whom she harbors a deep admiration.

  • Alternate Character Reading: Her family name is written simply as the character for "one". The reading means "before two."
  • Boyish Short Hair: This is part of her boyish charm, but she actually keeps it because it's easier to handle.
  • Clueless Chick Magnet: Majime naturally attracts and makes girls fall for her simply by being nice. While she knows other women falls for her, she is clueless as to why. Lily is one such "victim" of this, and notes how scary it is that Majime effortlessly swept her off her feet without even knowing it.
  • Comically Missing the Point: Most of the time, Majime does this, if she's not overanalyzing things so much that her brain fries itself.
  • The Comically Serious: How she got her nickname, as Majime is almost completely incapable of humor and has a tendency to overanalyze everything.
  • D-Cup Distress: Very subtly implied in the anime. When Loli asked her on tips for getting a larger bust, Majime noted how bigger isn't always better, as they obstruct movement and make it easier for perverts to fixate on her when wearing loose outfits. Later that same episode, she expresses jealousy at Loli's smaller, cuter figure, much to Lily's "annoyance".
  • Ditzy Genius: Majime is a prodigy at mathematics and other "hard science" subjects due to her amazing analytic capabilities. The trade-off is that she's absolutely miserable when it comes to social interactions.
  • Even the Girls Want Her: She's one of the most sought-after girls in the whole school, and she doesn't know why at all.
  • Good with Numbers: She can do mental calculations up to the tenth digit.
  • Hidden Buxom: While not noticeable due to her tendency to wear loose-fitting shirts, this image states her to have the biggest chest amongst the main cast. Which gets even bigger whenever Lily is fondling them.
  • Huge Schoolgirl: While this is not particularly played upon other than the fact she's taller than rest of the cast, official character info shows she's actually 1.7m tall.
  • Iconic Item: Her headphones. She wears them almost anywhere at any time, even during class and in the rain. The only times she's shown without them are when she's at home and during the Pool Scene, and even then they're still usually visible somewhere in the background.
  • Ill Girl: Downplayed, as she's not sick all the time, though Majime is rather prone to falling ill. She often catches colds or has fevers, usually due to stress and/or going out into the rain without an umbrella, and being sick also caused her to miss out on the highschool admission exams, thus landing her into Sainotama despite her otherwise high grades.
  • The Ingenue: Majime is somewhat Literal-Minded, and she is too polite and too much of a Nice Girl to realize whenever someone is not talking seriously with her.
  • In-Series Nickname: "Majime", which comes from her serious nature.
  • Lady Looks Like a Dude: Played with. Majime is noted to be rather handsome, due to her height, athletic figure, and Boyish Short Hair; however, she's girly enough not to play the trope straight.
  • Nice Girl: Majime is nice and helpful to a fault, as she complies with whatever anyone asks of her.
  • No Social Skills: While she does not come up as this towards the people around her, her Internal Monologue indicates she is absolutely clueless about how to deal with people, and she internally feels awkward interacting with girls her age. The absolutely nonsensical conclusion she has towards Saginomiya is just a facet of her incapability in understanding people.
  • Non-Uniform Uniform: She never buttons or tucks in her shirt, thus showing an orange T-shirt underneath. In addition, she usually wears crew-length socks while other students wear knee-highs.
  • Obliviously Beautiful: She's so attractive to her classmates and so effortlessly cool that Lily is left befuddled at her innate ability.
  • Oblivious to Love: She's completely ignorant of the fact that Lily—let alone many girls at Sainotama—is head over heels for her, even if the former's practically spelling it out.
  • Open Mouth, Insert Foot: Most of her interactions with Robo come off as this, as she gets so nervous that whatever she blurts out doesn't have a lick of sense.
  • Promotion to Parent: Played for Laughs. She behaves like Loli's "dad" in the classroom, with Lily being the "mom"
  • Rant-Inducing Slight: Curiously, she does it on herself. In the privacy of her own room at home, Majime blows a gasket overthinking her awkward interactions with Robo, and her rant is so off-the-wall that her mom starts worrying about her daughter's sanity.
  • School Idol: In the second year she's known as one of the gods.
  • Serious Business: This is what her nickname comes from, and the reason why she is a model student despite being not particularly smart (especially compared to Robo).
  • Stalker Without a Crush: She tails Robo and her friends and tries to know what makes Robo happy, owing to the fact that Robo is probably the only other person in her grade who is somewhat academically accomplished. Her intention was never romantic, but rather out of purely platonic admiration, but it comes off as obsessive and stalkerish.
  • Strong Family Resemblance: Majime looks like a one-to-one copy of her mother, only younger and with a lighter shade of brown for hair color.
  • Tomboy and Girly Girl: The Tomboy to Lily's Girly Girl.
  • Tomboy with a Girly Streak: While she's indeed a tomboy, she's not boisterous, sporty or physical, and she's more shy than she appears at first glance. She's a tomboy in the gentlemanly sense.

    Lily Someya 

Lily Someya
The Devilish Yuri Girl
Voiced by: Satomi Sato

A beautiful transfer student, Lily has a deep-rooted distaste for men, declaring herself a "fan of girls". Somewhat vain and confrontational, Lily has a crush on Majime and establishes a friendship with Saku.

  • Ambiguous Disorder:
    • Lily has a pathological androphobia that manifests with hives whenever she comes in direct contact with men... and Tanaka. Her classmates speculate that the hives manifest out of her hatred of men, but a blind trial proves that Tanaka may be an exception to the rule and that the hives may not be a psychosomatic problem. It becomes even weirder when Baka is infected with the Out of Character parasite in chapter 72, which somehow doesn't cause hives to develop when Lily touches her.
    • On top of the previous point, Saginomiya ponders on Lily's situation, as it's unclear whether she dislikes men because they may produce hives on her, or the hives caused her to develop a distaste for men.
  • Aren't You Going to Ravish Me?: Several of her interactions with Majime end up as this, as Majime's domineering manliness towards her gets the better of her, though Majime never quite realizes the feelings she arouses in Lily.
  • Attention Whore: She loves being the center of attention, and the manga makes it clear that it's part of the reason why she hangs out with Majime so much (the other reason being that she has a crush on her).
  • The Beautiful Elite: Lily is strikingly beautiful and is implied to be more affluent than her classmates.
  • Chivalrous Pervert: Lily rarely acts upon her basest, lowest desires (which are many) when she interacts with her classmates, so mostly everyone in class has a good impression of her because she comes off as friendly. Instead, she counts small interactions with her classmates as little victories, such as teaching Loli about fashion and styling just so that she can see her in the middle of changing, and interacting with Majime so that she gets manly/domineering with her.
  • Cloudcuckoolander: Subverted. This is the first impression she gives to her classmates when she introduces herself, as in not so many words, she declares herself to be a card-carrying lesbian on the prowl. However, she turns out to be one of the most grounded girls in class.
  • Covert Pervert: Lily's affection, friendliness and physical interactions with her classmates hide her inner desire to glomp them, fondle them and get indecent with them; however, she holds herself back well enough to leave a good impression in them regardless, so much that Loli and Majime consider her a good friend. Though her main preoccupation is to not be labeled as a pervert, it's also implied that she does it because she likes them as friends too, and doesn't want to undermine their friendship.
  • Does Not Like Men: As noted under Ambiguous Disorder, Lily has an overt dislike for men, due to physical interactions with them triggering a violent allergic reaction in her. According to the manga, she wasn't always like that, but because the boys (and men) around her were so raunchy and abhorrent with their showing of affection towards her, culminating in a rabid fan flashing his privates in her face, she ended up being traumatized.
  • Everyone Has Standards: Played for Laughs. She's so offended at the fact that Tanaka told Loli that couples have babies by submitting an application to the government that her admonishment makes Tanaka just try to set the record straight, only for Lily to realize that she doesn't want to mar Loli's ears with the truth.
  • Girly Girl: Of the posh and groomed variety.
  • Gyaru Girl: Played with. She sports the appearance of one and she grooms considerably, but her hair color is natural because she's half-Australian.
  • Hidden Depths: She is one of the most grounded girls in class in spite of hitting the ground running from the start, and albeit she does have her quirks, it's not to the outlandish extent of most of her classmates (at least not outwardly). She is also a surprisingly good friend towards Majime and Loli in spite of her kinks.
  • Irony: In spite of her manifested distaste of men, Lily has a crush on Majime, who is considered the coolest, manliest girl in the whole school. Majime has checks on all of her boxes, and has none of the disadvantages that she'd have if she pursued boys.
  • Lipstick Lesbian: Lily is a well-groomed Girly Girl and has so far only demonstrated romantic interest in other women, among them Loli, Majime, and Majime's mom.
  • Meaningful Name: Her name alludes to Yuri Genre which is named after lilies, which fits in the fact that she's a Schoolgirl Lesbian. This is probably the reason Tanaka doesn't give her a nickname.
  • Mentor Archetype: Towards Loli, who seeks to emulate her femininity. The problem lies in the fact that Loli tends to improvise with disastrous results.
  • Mixed Ancestry: Her father is an Australian while her mother is Japanese.
  • Multiethnic Name: Her last name is Japanese, but her given name isn't. This implies that her father may have adopted his wife's family name.
  • Nice Girl: She's a surprisingly doting friend for Loli and Majime in spite of her numerous kinks.
  • New Transfer Student: Transfers into Sainotama in the fifth episode.
  • Not So Above It All: When Loli accidentally shaves off her eyebrows and doodles on some extra thick lines in their place, Lily chides Baka for making fun of them, while she is trying really hard not to laugh herself. And then when she sees Loli's accidental Hime Cut...
  • Odd Friendship:
    • With Loli. Loli enjoys her company because she admires her femininity and looks up to her, while Lily tries to educate Loli in romance and sex topics, but fails because she doesn't want to mar Loli's innocence, babying her friend.
    • With Yamai, bonding over an instance where they were stuck in the school's rooftop and getting to witness a couple of girls having an intensely melodramatic discussion over their relationship.
  • Ojou: Implied. Though she grooms herself in a way that may appear as a Gyaru Girl at first glance, her tidiness and non-school garb imply that she has had an affluent upbringing.
  • Promotion to Parent: Played for Laughs. She has given herself the task of taking care of Loli in the classroom, much like a "mom" would. In turn, Majime behaves like the "dad".
  • School Idol: In the second year she's known as one of the gods.
  • Schoolgirl Lesbians: She's the token lesbian of the cast.
  • So Beautiful, It's a Curse: Her case of Does Not Like Men is a result of this trope; her beauty invited the worst from the male around her, culminating in a rabid fan flashing his privates in her face, she ended up being traumatized.
  • Thanks for the Mammary: There's no other way to put it. Lily really likes to touch or grope other girls' chests, with her most common "victim" being Majime and her Gag Boobs. This is only really evident in the anime, though, as she has much better restraint in the manga.
  • Tomboy and Girly Girl: The Girly Girl to Majime's Tomboy.
  • You Are What You Hate: She hates whenever the other girls lie to Loli and give her weird ideas about sex/romance. The problem comes from the fact that she herself babies Loli, keeping her ignorant for pureness' sake, Lily making herself an even worse offender.

    Hisui "Majo" Kujyo 

Hisui "Majo" Kujyo
The Occult Freak with Social Anxiety
Voiced by: M・A・O

Kohaku's older twin sister who is in the same class as most of the cast. She hardly shows up at school due to finding it hard to connect with other girls with her Nightmare Fetishist tendencies, although she earnestly does desire to make friends. She dresses in a long black cloak, earning her nickname "Majo"note .

    Airi "Nora" Nobara 

Airi "Nora" Nobara
The Cat Lover Who Cannot Trust Humans

A grumpy girl who transfered into the class in the second year.

  • Animal Eyes: Nora's irises are drawn as vertical slits like those of cats, rather than the standard design.
  • Animal Motifs: She behaves very much like a battered, people-wary stray cat. As shown in the character image, she also has slit pupils like a cat does. This is also where her In-Series Nickname comes from; "Nora" usually describes a stray animal—see, for example, Noragami.
  • Crazy Cat Lady: The joshikousei equivalent. She lives alone, she's unwarrantedly aggressive towards everyone, and she knows every single cat in her neighborhood; short of sustenance expenses, she'd probably adopt all of them.
  • Early-Bird Cameo: She has an unvoiced appearance in Episode 12 of the anime in a shot showcasing the girls' 2nd year class.
  • Emancipated Child: She lives alone in an apartment paid by her parents because she couldn't tolerate living with her dad after he lied to her all of her life regarding having a pet cat because of his allergies, the condition being that she'd sustain the prospective cat with her own earnings.
  • Face of a Thug: She is almost always grumpy towards everybody. Not towards cats, though.
  • Freeze-Frame Bonus: She appears in a split second during the ending of Episode 12 of the anime.
  • Hidden Depths: Deep down inside, Nora is a very lonely individual with severe trust issues.
  • In-Series Nickname: "Nora", or "Stray", for acting like a stray animal. (See Animal Motifs above.)
  • Jerkass: A notable example, since she's the only person who has managed to make Tanaka angry with her aggressiveness.
  • Kindhearted Cat Lover: Nora absolutely adores cats, collects accessories of them, and has an apartment full of cat toys and food just ready to adopt one. She even names all of the stray cats in her neighborhood and tries her damndest to be their friend, despite them always scratching and biting her.
  • Parental Issues: She hates her father with a searing passion, see Used to Be a Sweet Kid below.
  • Peek-a-Bangs: She wears her hair this way, with one eye constantly concealed by her bangs.
  • Tsundere: She tries to play it cool when bumping into Waseda at the cat cafe, saying that she doesn't particularly like cats or think they're cute or anything, though he isn't fooled.
  • Used to Be a Sweet Kid: Nora used to be just like Loli when she was a child, and was promised a pet cat by her father. Eventually, however, there was never any cat, and her father kept delaying again and again until one day she found out he's actually allergic, so pets are a no-go. She's been having major trust issues since.
  • What Is This Feeling?: In Chapter 83, Nora felt incredibly warm and fuzzy when looking at a lost Loli in the mall, thinking on how cute she looked. Her interests in Loli began growing after this point.

    Utako "Hime" Nakamura 

Utako "Hime" Nakamura
Two Faced Girl with the Power of Makeup Transformations
Click to see Hime in elementary school. 

A freshman and underclassman for the main cast, Hime is a girl who is stylish and posh, but is the daughter of a Ramen shopkeeper, using her appearance and demeanor to hide this fact. She is a friend of Tanaka from when she was in middle school and Hime was in elementary school.

  • A Friend in Need: She was the needing party in her friendship with Tanaka, and Tanaka delivered in droves without ever realizing she did it in the first place.
  • Act of True Love: Played with. When she gets to high school and meets Tanaka, she realizes that all her grooming and dedication to her fitness was not only to better herself, but for Tanaka too. She became the princess Tanaka told her to be.
  • Because You Were Nice to Me: Played with. Meeting Tanaka changed her life by being rude and annoying not only to her, but also to her father. Tanaka's biting criticism and insensitivity molded both Hime and her father into becoming the best versions of themselves they could be. The fact that Tanaka benefited her so much by being sincere and blunt made Hime be unbendingly grateful towards her.
  • Big Eater: She still eats as much as she did like when she was in elementary school through middle school, but she now makes enough exercise to compensate for it. As such, she's very fit.
  • Blinding Bangs: Her eyes used to be concealed by her bangs until she got her makeover. This is to indicate her poor self-confidence at that point.
  • Crush Blush: After she hurries back to the bathroom and scampers her classmates away to clean off her tears, she is visibly blushing, elated at the fact that Tanaka recognized her after so many years.
  • Deliberately Cute Child: She built herself into The Cutie through sheer determination and an awful lot of work because she greatly disliked herself in the past. This is due to the fact that Tanaka told her to just put on the makeup she liked so much in her handheld otome games.
  • Determinator: Baka basically snapped her from the road towards a Broken Bird back to this, and in Present Day she spends a lot of effort making herself the best in front of everyone.
  • Driven by Envy: She resents effortlessly beautiful girls (such as Majime and Lily, known as "the gods" at this point) with a passion because she spends most of her free time exercising and grooming to look cute.
  • Escapism: When she was younger, she played a lot of otome and makeup games mainly because, as a Fat Girl daughter of a faltering ramen shop, she wanted to the exactly the opposite of it. Baka effectively persuaded her to act on those wishes instead.
  • Embarrassing Nickname: She used to be referred to as "Butako" (pig girl) by boys in elementary school.
  • Fat Girl: She was visibly overweight in the past, complete with the You Are Fat insults and Embarrassing Nickname. She also had the body-image issues commonly associated with this trope.
  • Formerly Fat: She used to be fat and plain in elementary and early middle school.
  • The Friends Who Never Hang: Tanaka considers her a dear friend of hers in spite of having spent years without seeing each other. It's also implied that Hime became Tanaka's friend after she and Akane started to drift apart due to Saginomiya's absence, explaining why neither of them had met her before she enrolled in Sainotama.
  • Gamer Girl: She used to be a voracious player of otome and makeup games, until Tanaka told her to just to try it on herself.
  • Gyaru Girl: She became this between the time she moved away from Tanaka and when she enrolled in Sainotama, spending a considerable time and effort to become fit and learn how to put makeup on.
  • I Am Not Pretty: Invoked and played with. She is aware that she's somewhat plain under her makeup, but her reencounter with Tanaka makes her realize that this plainness is okay too, as this is the "Hime" Tanaka knows from before and recognized under Hime's makeup.
  • I Want You to Meet an Old Friend of Mine: Tanaka introduces Hime in this manner to Saginomiya and Akane.
  • Loner-Turned-Friend: Hime was a bullied and lonesome child before she met Tanaka, whose friendship changed her for the better.
  • Love Epiphany: She had intended to avoid Tanaka, but when she both recognizes her and calls her "Hime" like she's always wanted, she's too moved to even speak in front of her. Tanaka done yanked the rug from under her.
  • Meaningful Rename: She told Tanaka that her name was "Hime" (princess) because that's what she had always wanted to be.
  • Missing Mom: Hime's mother is conspicuously absent, even during her flashback.
  • Self-Applied Nickname: Unlike the rest of the cast, Hime's nickname was not given to her by Tanaka, but it's how Tanaka refers to her after she told her that this was her name. No one but Tanaka calls her that, and she's touched to the core when Tanaka calls her "Hime" once again.
  • She Cleans Up Nicely: It was a lot of work, but she basically turned from a Fat Girl to one of the most photogenic girls in her grade.
  • Ship Tease: It's implied that she loves Tanaka, and with good reason.
  • Signature Scent: Baka recognizes her immediately in high school because of the faint smell of tonkotsu broth she "inherited" from her father.
  • Stating the Simple Solution: Tanaka told her back in the past that if she enjoys otome and makeup games (of which she plays solely out of escapism), she might as well try it on herself. This, alongside Tanaka's push on her father, makes her remake herself for the better.
  • Tears of Joy: She's touched by the fact that Tanaka recognized her in spite of how much she has changed, and by the fact that she called her "Hime" once again.
  • Third-Person Person: She refers to herself as "Utako". Then Baka showed up and reminded her of her past and she let it slip, and referred to herself in the first person for a moment.
  • Tomboy and Girly Girl: In their friendship, she's now the Girly Girl to Tanaka's tomboy; this, however, was not always the case.
  • Undying Loyalty: She has a profound sense of respect and affection for Tanaka, whose presence changed everything in her life for the better. It's later shown that she loves Tanaka beyond all her weirdness and nonsense.
  • Weight Woe: Owing to her Formerly Fat past, Hime is extremely sensitive about high-calorie foodstuff and exercises religiously to, as she puts it, "stay thin despite pigging out".
  • You Are Better Than You Think You Are: Through the example of her father trying to better himself in response to Tanaka, Hime realizes that she too should strive to be the princess she wants to be, the world be damned. She dedicates her everything to achieve this, and by the time she's in high school, she looks like an entirely different person.
  • You Are Fat: She used to be on the receiving end of this, until Baka changed her life so profoundly that she lost most of that weight through vigorous exercising and sheer might of will.
  • You Gotta Have Blue Hair: She has pink hair, unusual in a series where the cast usually have natural hair colours, or has explicitly mentioned to have dyed their hair for fashion.

    Masataka "Waseda" Sawatari 

Masataka "Waseda" Sawatari
The Homeroom Teacher from a Famous University
Voiced by: Kazuyuki Okitsu

Waseda is the girls' homeroom teacher and math teacher, who is awkward and deadpan towards his students because of his dislike of hormonal teenagers.

  • Adaptational Early Appearance: The anime introduces Waseda immediately upon the first period in class, whereas the manga took five chapters for him to show.
  • Be Careful What You Wish For: While warning his students to not fall in love with him, as he likes older women, he secretly starts a hobby as a web musician in the hopes of gaining attention from an older female fanbase. This backfires horribly as Akane becomes his biggest fan, and starts getting infatuated with him after she learning that he is the very musician she adores.
  • Blind Without 'Em: Downplayed. While everything around him appears blurry without his glasses, Waseda could squint really hard at a certain point to train his focus, as shown during the part where Ota meets "Teishotoku-P" for the first time.
  • Composite Character: According to Bino, the character concept for Waseda was the combination of the author's friend and the "real" Teishotoku-P. Technically, though, Teishotoku-P is allegedly not an actual person, but an alias made up by Bino to upload the tracks that Ota listens to, which the author had commissioned.
  • Deadpan Snarker: His usual response to Tanaka and Yamai's antics, though sometimes the latter's nonsense gets the better of him.
  • Early Installment Weirdness: In his introduction, he makes it abundantly clear to the girls in class that he will not indulge in Teacher/Student Romance, which implies he has a closeted Joshikousei fetish. However, eventually, he is portrayed to have no fetish towards them (see also Not Distracted by the Sexy)—his type is the more mature Office Lady.
  • Everyone Has Standards: Although he tries to hide the fact that he is "Teishotoku-P" to Akane, he later chooses to tell her directly, as he'd much rather not lie to her after she poured her feelings towards his music.
  • Garage Band: He was involved in a number of bands in college, which all fell apart due to his bandmates' surprisingly stupid reasons. This happens to be the reason he became a solo composer and arranger later.
  • Has a Type: While he was introduced as if he has a closeted attraction towards Joshikousei, later chapters shows he actually likes college girls—especially when they're on a job-interview business suit.
  • Hidden Depths:
    • Waseda is a hobbyist musician and arranger who is a fan of Hatsune Miku and is a famed composer in otaku circles known as "Teishotoku-P".
      • Elaborating on this aspect, it's shown that he has a perfect sense of tone, and as noted by Nora, he can even attract cats from the pitch of a lure cat toy alone.
    • He is a very dedicated and professional teacher in spite of coming off as a delusional creep due to his off-the-wall introduction.
  • In-Series Nickname: "Waseda", since Tanaka thinks he looks as if he comes from a high ranking university such as Waseda University.
  • Jerkass Has a Point: He makes a point clear in his introduction to the class that he doesn't want any of them to become close to him. Considering that he's the receiver of all their weirdness with none of the context, he does have a point.
  • Kindhearted Cat Lover: Waseda seems to like cat-shaped accessories and bought a bunch of cat alarm clocks in the manga which he appears to appreciate. Until they start meowing incessantly and he can't find the snooze buttons, anyhow. And felines seem to love him back, as chapter 73 of the manga has him going to a cat cafe and hogging all of the cats there, much to Nora's annoyance. Even the particularly hard-to-get ones would readily show their stomachs to him.
  • Last-Name Basis: With all the girls in his class, not only due to the fact that he's their teacher, but also because, among themselves, they seldom refer to each other by their last names in the first place.
  • Not Distracted by the Sexy: Waseda tries to test his type by going to a beach full of sexy girls in revealing bikinis during The Stinger of episode 8, to expected results.
  • Not So Above It All: While Waseda tries to be professional and stern at all times on campus, he couldn't help but whip out his phone to take selfies of himself with Baka and Yamai, who got their heads stuck in a huge cutout. One photo even has goofy filters slapped onto every face, including his own.
  • Office Lady: This is his type. Waseda has a fetish for mature women in what he describes as "job interview suits".
  • The One Guy: Waseda is the only male character of note in the manga.
  • Only Sane Man: He is this for all the girls in class, as he is the wall on which all of their weirdness resonates. He greatly dislikes the fact that he is this, however.
  • Opaque Lenses: His glasses are often illustrated with these, and his actual eyes are rarely shown.
  • Paper-Thin Disguise: He throws together one to disguise himself from Ota when she comes to his booth for Teishotoku-P's merch. She somehow doesn't notice it's him, even though the better part of his face is plainly visible, and he only put on a do-rag, removed his glasses, and took off his coat.
  • Pen Name: He publishes his Vocaloid productions under the pseudonym "Teishotoku-P", or "Low-Income Producer".
  • Prematurely Bald: He fears the stress of having to constantly deal with Yamai and Baka's antics will give him this.
  • Running Gag: His one-on-one confrontations with Yamai to straighten her out constantly has his glasses crack up and break over how mentally painful her replies are. It reaches a point where he has to lug around a briefcase full of replacements, and yet still loses upwards of four pairs in a single confrontation with her.
    Waseda: Yamamoto, I have half a mind to make you pay for my glasses.
  • Sitcom Arch-Nemesis: Yamai, due to her Chuunibyou tendencies and terrible performance. Baka is occasionally this as well, but not as frequent as Yamai.
  • Small Role, Big Impact: Through his music, he helped Akane through the difficult times she experienced during middle school as she had began straying away from Tanaka.
  • Stern Teacher: As much as he can. Both Tanaka (dumb as bricks) and Yamai (procrastinating and giving incomprehensible excuses) are the banes to his existence.
  • The Stoic: He is constantly slightly miffed, and he rarely changes expressions, even when he's angry. This is due to the fact that he consistently faces annoying, yet inconsequential amounts of crap daily.
  • Weirdness Magnet: That's not to say Waseda himself is not plenty weird, but considering the nature of his students, he ends up being the Only Sane Man. It's not only that their interactions with him are weird, but he usually gets involved when the girls are at the apex of being their weirdest on that given day, leaving him befuddled and with more questions than answers.

Supporting characters

The nurse on duty at Sainotama and fellow Chuuni of Yamai.
  • Chuunibyou: The reason why she got along so well with Yamai, though according to the manga it seems like an act.
  • Cloudcuckoolander: She has about the same level of IQ as Yamai and Baka, as she entertains Yamai's antics and is also caught in the large cutout that they got stuck in on the way to school. Not by accident, but by deliberately going into the storeroom it's placed in and sticking her head into it.
  • Eyes Always Shut: Unless she's showing her Chuunibyou side, her eyes are always shut.
  • Only Known by Their Nickname: "Shiikyon" is just a nickname that she tells students to call her, and her real name is not known.

Mitsu Momoi
Voiced by: Ayaka Nitta
Loli's loving grandmother and legal guardian.
  • All There in the Manual: Grandma's name is only revealed in a single panel in the manga, and is not mentioned at all in the anime
  • Doting Grandparent: She's one to Loli in every way possible. Fittingly, Loli adores her.
  • Eyes Always Shut: Except for the one picture of her as a child, grandma's eyes are always depicted as narrow lines.
  • Small Role, Big Impact: She's the reason why Loli is the way she is, that is, childish for her age and profoundly sweet.
  • Strong Family Resemblance: Loli closely resembles her grandma when she was her age.

Rie "USB" Mikami
Voiced by: Sayaka Senbongi

  • Ascended Extra: She doesn't even have a first name in the manga, appearing in all of one page gushing over Lily's beauty, and that's about it.

A student of a nearby all-boys school. He rides the same morning train as Robo and develops a crush on her, though the combination of her aloof personality and his own awkwardness make this prospect difficult for him.
  • Big Ol' Eyebrows: His eyebrows are drawn as immensely thick strokes in the manga, while the anime changes them to rows of thin lines instead.
  • Birds of a Feather: He is the kind of boy who, at the very least, knows how to appeal to Robo's curiosity... which is, by being as weird as her.
  • Cannot Spit It Out: Despite him thinking like a romance novel, complete with everything he wishes to say to her, Takahashi just couldn't do it when he's faced with Robo herself in person. The topic then veers violently towards something else out of left field. This only adds to her impression that he's an awkward dude and something of a weirdo.
  • Cloudcuckoolander: His line of thinking is...unique, to say the least. Takahashi is very sensitive, yet unusual at the same time, of people and their relationships.
    • During one train ride, he overheard how Robo would use a prospective "boyfriend" as her human test subject, and he immediately pictured himself in that position, musing on how it must have been his destiny.
    • On another occasion, after one look at his friend Aoyama's new family photo, he spots a girl who looks similar to Robo, and immediately comes to believe that Brother–Sister Incest will ensue owing to their talk earlier, meaning his chances with her are effectively zilch. He went on a day-long Heroic BSoD, culminating in him making a buffoon of himself in front of Robo, who turns out to be an Identical Stranger. Needless to say, she's very much not amused.
  • Dogged Nice Guy: Considering how weird Robo is, he has little of the way of a gauge to determine how well or how badly he's doing in his pursuit of a relationship with her. If anything, he's dedicated, if lost at it.
  • Hidden Depths: Takahashi is a budding novelist, thus his train of thought is often flowery and descriptive worthy of Purple Prose.
  • The Not-Love Interest: He's as close to a "boyfriend" as Robo has, which going by their mutually weird trains of thought, is just as remote to the definition as it can get.
  • Stalker with a Crush: A rather tame example. It's amazing how Robo isn't weirded out by this, though she does find his awkwardness confusing.

How well does it match the trope?
