Ousai Academy Student Council

Takatoshi Tsuda

Voiced by: Shintarō Asanuma

Protagonist.

-Ranko's candid and unbiased description of Taka (Chapter 150.5)

The main character, a first-year transferee to Ousai, an erstwhile all-girls high school which has recently turned co-ed, because it's close to his neighborhood, only to be dragged into the position of Student Council Vice-President and representative for the nascent male student body. He was a first year when the series started, but later went up to second year.

Tall, even-headed, and academically middling, Tsuda is the straight man in the student council, and the target of 90% of the sex jokes in the story.

---

• Accidental Pervert: Whenever Shino or Aria catch him in unfortunate situations. The anime-only "Squid and Takatoshi" segments are built entirely around this. ^note Japanese culture portrays dried squid as smelling like semen.
• Affectionate Nickname: Uomi refers to him as Taka-kun.
• Beware the Nice Ones: Capable of quite the intimidating glare when the girls go too far. It helps that such moments are some of the rare occasions his normally ignored stature is invoked.
• Book Dumb: It's noted that he's not particularly great in regards to his academics. Although later on, the other members of the Student Council eventually help him to get more respectful grades.
• Celibate Hero: Certified by Shino in Chapter 50, after finding his room does not smell like semen.
• Chick Magnet: Has gathered an Unwanted Harem and is noted to be attractive even by background female characters. In fact, Ranko mentions that if it weren't for the fact many people think he and Shino are dating, he'd be approached more often.
• Covert Pervert: Not as bad as the girls he gets surrounded with, but he still has his moments. This is evident in the end of Chapter 102, where he says "Hey, you'll get me excited" when Shino asks to spank his butt since she can't clap her hands while holding something. He's also sometimes agreed with or didn't deny when the girls have called him a masochist.
  • Later chapters have gags based on how even he is not immune to Aria's boobs, often finding his gaze drawn to them or, in one case, having to slump to hide his Raging Stiffie after she leaned into him from behind. ^note Amusingly contrasted to his lack of reaction to Shino when she purposely does the same to literally get a rise out of him.
• Deadpan Snarker: 90% of the tsukkomi in the series (remember that it is a yonkoma where the punchline is often a tsukkomi) is from him, making him a highly prolific snarker almost rivaling Kyon in terms of snark frequency.
• Gentle Giant: He's quite tall, and not just next to Suzu.
• Heroic Self-Deprecation:
  • When his class has to practice for a doubles tennis match in Chapter 187, the girls compete to see who gets to be his partner, and he takes this as if the loser has to be burdened with him. Kenji immediately calls him out on his thick-headedness.
  • In a later chapter, he tells Ranko that he doesn't consider himself to be even remotely close to Shino's ballpark in terms of being considered an item. He unjustifiably deems himself below her, which the girls around him are quick to notice with surprise.
• Hidden Depths:
  • He has decent storytelling chops, if the couple of gags featuring them is anything to go by.
  • As shown in Chapter 455, he has superb hearing, being able to tell between Mori and Uomi through the phone, even when Mori is a dead ringer when imitating Uomi, and on top of that, recognizing that it was Mori who was doing the imitation in the first place. This lends to show just how much attention and respect he gives to the girls he meets.
• I Can't Believe A Girl Like You Would Notice Me: Takatoshi has a very hard time believing that the girls of the Student Council like him as a boy. This is exacerbated by the fact that, due to school policy, they're basically not allowed to tell him. He does consider them his best friends.
• Informed Attractiveness: It's heavily implied that Shino scouted him immediately into the Student Council partly due to this, as no other male students were even remotely considered. She even made him vice-president to have him at her side in spite of him having neither the qualifications nor the grades to warrant it. He was just too enticing a snack for her to overlook. The fact that later on most girls he meets become interested in him serves to confirm this.
• Innocent Innuendo: When he and Mori-san (the Vice-President of Eiryou High School) are together, they get along so well that it actually frightens the other girls who are interested in him. It doesn't help that they are prone to saying things that can really be taken the wrong way. Her second appearance has Mori returning a key to him, but her wording makes it sound like she's inviting him to spend the night at her house. Another chapter has Mori beg Takatoshi to keep the fact he walked in on her changing in his living room (she thought it was Uomi's house) a secret, but their response to a question about what they were talking about simply made people more suspicious.
• Innocently Insensitive: His Oblivious to Love aspect sometimes makes him come off as this. For example, Mutsumi once tried to ask him out to dinner, using his help as Judo club manager as an excuse. He turned her down, saying he was helping for the sake of helping, not for a reward. He is then puzzled as to why Mutsumi was so dejected.
• Launcher of a Thousand Ships: While not a typical harem anime lead, Takatoshi is shipped with just about every female character barring Chiri (who is often paired up with his best friend Kenji instead).
  • In-universe, Ranko and many others see him and Shino as a secret couple, but people suspect Uomi has romantic feelings for him, the Judo Club is well aware of Mutsumi's crush on him (even the otherwise aloof Toki) and Uomi, Shino and Suzu are all worried about how easily he gets along with Mori.
• Living Emotional Crutch: To Suzu, albeit he doesn't quite realize this. Taka is a fundamental source of security and happiness for Suzu, as he's the person she seeks whenever she's frightened or wants physical affection.
• Meta Guy: There are gags in the manga which include him serving this purpose as a sort of Fourth-Wall Observer.
• Mundane MacGuffin Person: He's one, in the function of being a prospective romantic partner for most of the girls in the story. The competition for him is surprisingly cordial between the girls, as none of them pursue him seriously out of respect for the others, but there's an unwritten rule: don't press your luck. If any one of them gets too close to Tsuda, the others will promptly intervene to stop that nonsense. This is respected by all of the girls regardless of the advantages they have (like Uomi, who is almost completely unimpeded to pursue him), and even when the other girls don't mind that much (like Suzu, who is often in need of Tsuda's physical help).
• Nice Guy: He's usually willing to help out wherever possible. This is a major reason so many girls are attracted to him.
  • When explaining just how popular Takatoshi is among the female population of the school, Ranko actually lists his nice guy attitude first before mentioning his looks.
• "No. Just… No" Reaction: In Chapter 48, he gets one from Aria's statement, which took it too far:
  Tsuda:It's so hot. I want to go to the beach.
  Suzu: When you say "beach" the first word that comes to mind is "swimsuits".
  Shino: When you say "swimsuits", the first word that comes to mind is "butts"
  Aria: When you say "butts", the first word that comes to mind is "enema"
  Tsuda: No way... No freaking way. That is so wrong.
• Noodle Incident: Whatever it was that he wrote in the school paper was enough to bring anyone who read it to tears. We never find out the contents of his essay, especially since the images shown while Shino and the others read it (something about a cat, a sailor, and a woman) had nothing to do with the actual essay's content. (Much to his frustrated bafflement.)
• Not So Above It All:
  • One of the main reasons he is in the student council, notwithstanding that he was forced to join, and in spite of the fact that first, he's academically underachieving compared to Shino, Aria and Suzu, and second, that Shino and Aria proposition him for outrageous sexual stuff, is that he enjoys being there.
  • Occasionally he'll slip up and reveal his more perverted thoughts.
  • In one chapter, Uomi finds a porn mag in his room.
• Oblivious to Love: Doesn't seem to be aware of the feelings of the girls attracted to him (particularly Shino) — with the exception of Yokoshima-sensei whose "love" is pretty much an open desire to have her way with him. Uomi calls him the Flag Crusher because of this.
• The One Guy: At least in a major role.
• One-Steve Limit: Albeit an extremely minor subversion, in Chapter 60 there's a mention of another Takatoshi in the theater club.
• Platonic Life-Partners: With Suzu, on account of both of them being first-years and paragons of sanity in the Student Council.
  • On the other hand, as hinted in the OVAs, Suzu herself might not want things to stay this way.
• Really Gets Around: Played for Laughs and overwhelmingly subverted. Shino, Aria, Kotomi, Uomi and Ranko tout him to be a Hormone-Addled Teenager and considerably more perverted than he actually is at every single opportunity they have. Albeit he's certainly not made of stone, he's nothing short of a gentleman towards all girls he meets. If anything he's the least hormonal/pervy boy anyone in the manga comes across, being the wall on which they throw all their own collective pervyness at, and as a matter of fact, it's one of the main reasons they like him so much.
• Running Gag:
  • There is much ado about Taka being a virgin among the girls at school, which counts as Hypocritical Humor because there's no indication that they're not virgins themselves.
  • As mentioned before, Taka is reputed to be a Hormone-Addled Teenager, which is ironic, as he's among the least hormonal characters in the whole story.
• Ship Tease: With most of the girls in the story, but mainly with Shino, to the point that the student body essentialy considers the two of them an item.
• Straight Man: He's the one who keeps the other Shino, Aria and Kotomi in check, and usually provides Deadpan Snarker responses to them.
• Student Council Vice-President: While nowhere near as perfect as Shino is, he's grown into the role and is respected by staff and students for it. Yokoshima-sensei observes during a PTA meeting that Takatoshi is known to put all his effort into his duties as Vice-President. Shino has also made it clear that he will inherit her position when she graduates (considering that no-one ever wants the job).
• Twice Shy:
  • He does seem at least a little attracted to Shino, but due to her perverse nature, and especially the bad publicity it would cause thanks to Ranko Hata (and who has spread a rumor they were already dating), he never makes a move on her.
  • He is also not a stranger to Uomi's advances towards him, since they're very close.
• Umbrella of Togetherness: With Shino in the fourth episode of the anime.
• Unwanted Harem: Played with. Shino, Mitsuba, Yokoshima-sensei, Suzu, Uomi, and possibly Nene. There's also quite a bit of Ship Tease with Aria, less but still present teasing with Kaede, and Kotomi would be even more forward if she wasn't his sibling. However, contrary to the trope, they're not actively "fighting" for his affections, and all of them are in cordial terms.
  • In addition, Hata reveals that he's very popular among the female students and it's only the fact most people think he and Shino are secretly dating that keeps them from approaching him.
• Urban Legend Love Life: The sheer number of girls interested in him and the occasional Boyfriend Bluff have caused other people to assume he is a playboy from time to time.

Shino Amakusa

Voiced by: Yōko Hikasa

Ousai Student Council President.
Brilliant and beautiful.
A superb athlete and good at housework.
The perfect human.
Scared of tall places.
Has a childish love of festivals.
Worried about her small breasts.
"I'm just sexually frustrated!!"

-Ranko's candid and unbiased description of Shino (Chapter 150.5)

Current Student Council President of Ousai Academy. On the surface she's the image of the straight-A student — serious, diligent and talented with most subjects. Behind that, however, she's quite the pervert.

---

• A-Cup Angst: While she's definitely larger than A-Cup, she still wishes that she was bustier. This leads to situations where she takes sly digs at Aria (mentally or verbally, though mostly the former) or vice-versa. Her sly digs also find a new target in Uomi, after Shino found out that Uomi actually has sizable boobs. The irony of it all is that most of the people that know her don't mind that about her nearly as much as she does, given that she's a stunning girl to begin with.
• Absurd Phobia: Played with. Shino is acrophobic (afraid of heights), which is actually rather common. However, she panics whenever she's a few feet from the perceived ground, like on top of a chair. Girl really needs to have her feet on the ground...
• The Ace: She's the top student of Ousai, is quite athletic, and it's occasionally shown that she is the go-to person for school related issues for which she always has good advice (Mitsuba, for example). Well, her perverted response is interpreted otherwise, anyway.
• Affectionate Nickname: Uomi refers to her as Shinocchi.
• All for Nothing: For all her huffing and puffing about her chest size, no one she knows has ever faulted her for it. She's beautiful, smart and overachieving enough for that not to matter in the slightest.
• Can't Act Perverted Toward a Love Interest: Inverted. Shino is obviously interested in Tsuda and has no problem saying extremely perverted things around him. However, whenever Tsuda actually says something perverted (or when she thinks he's saying something perverted) directed at her, she gets extremely flustered. It is implied that on some occasions, she deliberately acts perverted towards Tsuda to cover her real feelings for him.
• Clingy Jealous Girl: While she never openly shows this attitude towards Takatoshi, the show strongly hints that she wouldn't take it well if he does date anyone else.
  • At one point in season 2 she asks if he has a girlfriend, and when he replies that he doesn't, she seems relieved and quietly mentions that she wouldn't know what to do if he did.
  • In episode 6 of season 2, she invites him to a fancy restaurant after becoming a pop idol. She then sees another woman approach him, despite having reserved the entire restaurant. He then introduces her to Shino as his girlfriend, who looks just like her, and is quite disturbed by that. In this example, it turns out she was just having a dream of what would have happened if she became an idol. However, it's likely she would still be quite upset at him if he does date anyone other than her.
  • In episode 9, one of Uomi's relatives marries one of Takatoshi's relatives, making them related by marriage. As a result, Uomi asks him to call her "onee-chan" (big sister), and she refers to him as "Taka-kun". When he tells Shino this, she makes a pouty face and grumbles. When Aria asks her why she looks upset all of a sudden, she claims it's because she had food in her mouth.
  • In episode 13 of season 2, she shows up at Takatoshi's house to drop off some food for him and Kotomi after hearing that their parents weren't going to be home that night. She's startled by Uomi being there as well, and insists on staying to make some more food too. And after Takatoshi says they should get going after dinner, Uomi assumed she was going to spend the night there. Shino, who was going to head home, then also immediately changes her mind and stays as well.
• Even the Girls Want Her: She has her female fans within the school.
• Expy: Of Shiho from Idol no Akahon by the same mangaka. The difference is that Shino is a couple of years older and where Shiho uses an even mixture of intentional sexual talk and Freudian Slips, Shino is all-intentional all the time. It gets lampshaded when they meet in Shino's dream.
• Friendly Rivalry: With Uomi, for Taka's affection. They are close friends, and both like each other almost as much as they like Taka.
• From the Mouths of Babes: As revealed in flashbacks, she's always had her mind in the gutter. In elementary school, she asked the student teacher if she was a virgin.
• Girlish Pigtails: She used to sport this when she was at middle school.
• Grass is Greener: A mutual one. Shino envies the fact that Uomi became a member of Taka's family and is regularly at his home, while Uomi envies that Shino gets to be with Taka in every day of the school week.
• Green-Eyed Monster: She gets clearly jealous when Uomi uses her newfound closeness as Takatoshi's in-law to start aggressively flirting with him.
• Groin Attack: With her dolphin, she (accidentally) hit a man on the crotch in the Beach Episode.
• Hairstyle Inertia: Shino is blessed with long, stark-black hair, which is so persistently sleek and immaculate that she doesn't get bed-hair. She has also sported the same hairstyle since she was in grade school.
• Heroic Self-Deprecation: Related to her A-Cup Angst. Shino is so preoccupied with her relatively small bust that it's almost a complex for her. However, this is entirely unwarranted, as she's a beautiful girl to begin with.
• Heterosexual Life-Partners: With Aria.
• Hidden Depths:
  • Albeit she is the first to touch on perverted subjects and outrageous topics, Shino never acts upon her statements, and really touches upon them to get a reaction from her colleagues, especially from Takatoshi, thus implying that she does it just to get his attention.
  • It's implied that Shino may be using her hyper-sexualized reasoning to approach Takatoshi because she doesn't know how to approach him romantically. This has played completely against herself, as he remains entirely unaware that she likes him.
  • Although she's showered in praises due to her academic acumen, popularity and beauty from the school body, it's shown that Shino gives this little importance compared to the input by her partners in the student council. To her, it's only them who get the whole picture, and theirs is the opinion that matters to her.
  • It's shown that Shino craves to be doting and kind to her friends, but she's not particularly good at it.
  • Shino dislikes that her fellow students don't take school as seriously as she does. Kinks and everything, being an upstanding student is a tenet for her.
• I Know Mortal Kombat: How she won the Judo match (watching Boys' Love turned out to be useful for her...)
• Informed Ability: Her high grades. Downplayed in the anime when she is shown to be the top of her grade.
• The Insomniac: A downplayed Type A. She couldn't sleep before the Sports Festival due to being too excited, and again with the Cultural Festival.
• Irony: Even though she's attracted to Tsuda, and for all her kinky thoughts, in the manga Shino has never once tried to approach him with romantic intentions.
• Large Ham: She can get this way at times, especially if it involves cracking a joke at Takatoshi's expense.
• Lovable Sex Maniac: Nearly impossible for her to say something, or see something, without sexual innuendo.
• Malaproper: She'll occasionally blurt out really obscene things that sound similar to more innocuous phrases, such as saying kinbaku (rope bondage) when she's talking about the Kinkaku temple. Given her personality, it's difficult to tell if she does it on purpose.
• "No. Just… No" Reaction: During an overnight stay at school, the Student Council is eating with Naruko, who complains that she's getting wasted, to which Takatoshi tells her that it's due to her drinking on an empty stomach; her retort makes Shino stumble upon her words:
  Naruko: Even though my stomach is full of enema liquid... huh.
  Shino: Are you really... No... Are you serious?
• Not So Stoic:
  • The usually collected Shino gets giddy like a kid every time there's an upcoming school event or class trip. There is indeed a little girl still inside her, sex jokes aside.
  • Albeit she brings up sex in about 90% of her conversations, Shino is surprisingly bashful when it comes to actual contact with Takatoshi, meaning that she's mostly bark and no bite.
  • During the Student Council President Election arc, Shino behaves calmly, just like every day, but once it's announced that she won by a landslide, her knees give out from relief, as she actually felt a great pressure throughout.
• Otaku: Sex maniac aside, Shino has been shown to have an Otaku level of admiration for history and historical sites from the Class Trip episodes.
• Perpetual Frowner: Played with. In the manga's art, she almost always sports a slight scowl (especially in the earlier half of the manga), which adds to her reputation at school as a serious person in spite of being considerably more wacky and outgoing than how she appears.
• Quaking with Fear: She trembles due to her fear of heights. She tries to hide it by saying she's quivering in excitement.
• School Idol: Is likened to one, though it doesn't particularly affect the plot.
• Snark Ball: Particularly, when she's around Yokoshima-sensei or Hata.
• Squee: Her exact reaction to the Kinkaku.
• Student Council President: Complete with Red Armband of Leadership.
• Teru-Teru Bōzu: She hangs one so that it doesn't rain the day before the pool opening day... and later turns it upside down when she learns that Hata will be taking pictures of her in a swimsuit.
• Tsundere: Though less belligerent than most cases, it becomes more and more apparent as the story develops and she starts falling for Takatoshi. Officially lampshaded as of Chapter 177, in Dejima's head about the cast.
• Twice Shy: She has a crush on Takatoshi, but due partly to her perverted nature, and the bad publicity it would cause thanks to Ranko Hata (who has already spread rumors she was dating him already), she never openly admits her feelings to him.
• Uke: When Mitsuba mentions that the Judo Club is practicing Ukemi, Shino asks where the Seme is.
  Shino: If there's an Uke, then there should be a Seme!
• Umbrella of Togetherness: With Tsuda in the fourth episode of the anime.
• Unkempt Beauty: Invoked and subverted. During an overnight stay with the student council, they're complaining about bed hair, and she joins in, notwithstanding that her hair is always immaculate and unperturbed.
• Why Did It Have to Be Snakes?: She doesn't do well with either snakes or insects.
• Yamato Nadeshiko: On the outside at least.
• Yaoi Fangirl: Which eventually helps her win a Judo competition.

Aria Shichijou

Voiced by: Satomi Sato

Ousai Student Council Secretary.
Daughter of the famous Shichijou Group.
Has a gentle personality and good manners.
A bit of an airhead and makes bad puns.
Has giant boobs.
"There's a fuzzy feeling in my butt."

-Ranko's candid and unbiased description of Aria (Chapter 150.5)

Shino's best friend and Student Council Secretary. Despite her affluent upbringing, she tends to follow her friend's mental processes.

---

• The Ace: Not as prominently as Shino, but Aria is second only to her when it comes to grades, appears to be generally considered the more beautiful of the two, is a master calligrapher, and later revealed to have been a tennis player on the national level during junior high, before her breasts grew so big playing became painful. She's also probably the most outright perverted main character in the series (while others, particularly Shino, occasionally make references to more mainstream fetishes like whipping, Aria regularly takes them all to the realm of the utterly twisted and bizarre), but whether that's an achievement for her to be proud of is a matter of opinion...
• Affectionate Nickname: Uomi refers to her as "Aririn".
• Ass Shove: Has a not very well hidden fetish for it.
• Auntie Pennybags: While incredibly wealthy, she doesn't flaunt her wealth (purposely). She's also quite happy to share her good fortune with her friends, even once treating the entire Judo Club to dinner.
• Beware the Nice Ones: Despite her Perpetual Smiler exterior, please remember she's an S type.
  • Among other things, in chapter 188 when they practice tennis, she uses showing Tsuda how properly hold racket as an excuse to hug him from behind - and to try to use her strap-on on his behind.
• Boob-Based Gag: Her boobs are so much the subject of numerous gags that it's pretty much her defining trait. Chapter 261 of the manga implies she's an H cup.^note About equal to the North American G, or Commonwealth F.
• Brains and Bondage: Happy to play both the S and M sides too.
• Butt-Monkey: A mild example. She keeps getting accidentally fondled, inappropriately touched, or somesuch. Considering it's Aria, her reaction is typically arousal.
• Cloudcuckoolander: Spaces out at the bottom of the staircase before realizing that it isn't an escalator, stands in front of the Student Council room thinking the doors are automatic sliding ones before Takatoshi asks her what she's doing, and actually thinks her chest has suddenly become lighter, when what has actually happened is that she has bumped into Suzu.
• Deadpan Snarker: Always smiles, but she gets especially cheery when she's making a dark or perverted joke (especially if it's a dig at someone else).
• The Ditz: Played With. She's witty enough to have comebacks and jokes, so it's up for grabs whether she's actually ditzy to begin with, or just behaves like that for shits and giggles.
• Everyone Has Standards:
  • Even though she has a sizeable amount of fetishes and her head is filled with kinky thoughts, not once does Aria do it to a party without consent (though she does joke about it a lot).
  • Sure, talk all the kinky stuff you want with Aria. Just don't get too close to Taka, because that's not cool.
• Fiction 500: Mansion with grounds large enough to get lost on? Check. Room in said mansion that's entirely gold? Check. Privately owned mountain? Check.
• Genius Ditz: She's among the top students at school.
• Going Commando: She nearly never wears undies, and on outings she often misses a piece of outerwear or two. Apparently her family doesn't wear clothing at home.
• Heterosexual Life-Partners: With Shino.
• Hidden Depths:
  • It's shown that Aria, underneath all that sleaze, really enjoys the company of her friends and strives to provide for them the boons of her family fortune. Girl might be many weird things, but she's not greedy.
  • When Taka is acting as her butler for one chapter, it's shown that she likes being pampered and cuddled, particularly by Taka.
• Irony:
  • For all her lasciviousness and masturbatory and sadomasochistic jokes, she may well be a virgin (but one with a lot of kinks) and a complete stranger to romance.
  • Related to the previous point, and as mentioned in Hidden Depths, she really likes tender things too.
• Line-of-Sight Name: She wanted to name Taka's new cat "Tama" (balls/testicles) because it went into the bag they had it on at the Student Council room and it reminded her of a ballsack.
• Lovable Sex Maniac: Unlike Shino, she's into more kinky kinds of sex, including bondage and wanton nudity.
• Love Epiphany: In Chapters 277-278, Takatoshi picks her as his romantic partner as part of a drama they were roped into. He explains his reasoning (he can't pick Shino due to Hata's rumors, and picking Suzu would be awkward as they're classmates) but he fails to notice Aria blushing, and since then her behaviour has noticeably changed, now getting jealous right alongside Shino and Suzu rather than treating him as a plaything like before.
• Mundane Object Amazement: What's Aria's special dinner? Ramen!
• Ms. Fanservice: Not only is she very well-endowed, but she's very much a kinky and horny Loveable Sex Maniac.
• Nice Girl: Aria is a surprisingly courteous and kind girl for a person as kinky as she is. She also spares no expense at treating her friends for perks as much as she can.
• Not So Above It All: It's implied that Aria, even with her off-the-wall personality, is not past the possibility of a more tender relationship with a boy, Taka being the most immediate candidate.
• Not So Stoic:
  • While it's subtle, it's shown that Aria doesn't like girls getting close to Takatoshi in spite of expressing the least amount of attraction towards him compared to the other girls. If someone wants to glomp Taka, they'll have to get past Aria first.
  • In spite of her outrageous statements and wild imagination, it's shown that Aria is just as prone to getting flustered as Shino and Suzu, and for the exact same reasons involving Takatoshi. However, it's important to point out that most of the time, it's her who makes people flustered.
• Ojou: Invoked and Subverted. She has the appearance, the wealth and the demeanor, but her kinks rule her out almost completely.
• Out-of-Character Moment: Aria has this tendency to start saying something perfectly decent... only to end the sentence in outrageously lewd manner with a straight face. The rare exceptions tend to shock everyone who had time to get used to her antics.
  Tsuda: This great! (they are out eating)
  Aria: Yes, delicious. (beat) The meal I am eating with everyone is delicious.
  Everyone: She unexpectedly said something beautiful!!
• Perpetual Smiler: Even when talking about BDSM play. Even while crying over Tsuda's story!
• Running Gag: She has a bunch.
  • Turning every conversation she has towards sexual innuendo;
  • Her going commando;
  • Aria also always has enemas ready to use, and always tries to insert them into conversations.
• Sexy Secretary: To Shino.
• Ship Tease: In addition to some early ones with Shino, she gets them with Tsuda, especially in later chapters.
  • She blushes when Tsuda "confesses to her" after he was told to adlib final scene of drama where his character picks which adoptive sister he loves. Shino and Suzu were not amused, but he had good excuse: He picked Aria, since she was least likely to cause gossip, as he hadn't raised any flags with her... Until now. In the past, she would just crack a joke at his expense.
  • In chapter 297 she gets Tsuda to accidentally agree to be her temporary butler. She uses this as an excuse to get him to clean her ears (which has romantic connotations in Japan), play games together and read her a bed-time story, something her regular butler is revealed to have never actually done for her. She also doesn't mind when he accidentally walks in on her in the sauna.
  • In Ch. 343-344 she ropes the rest of the group into being her servants. Tsuda is the one who is the more personal, such as reading to her with Aria on his lap. In Ch.344 she can't sleep and it ends with Tsuda cooling her with a fan... while she thinks to herself that she still can't sleep and wonders why her heart is beating so fast.
• Single-Target Sexuality: She has only ever shown romantic interest towards Takatoshi, in spite of her wide array of weird sexual experiences.
• Stupid Sexy Friend: As mentioned in his Covert Pervert entry, even Takatoshi sometimes can't resist looking at her boobs or once getting a Raging Stiffie from having them accidentally pushed onto his back.
• Too Kinky to Torture: The fact she didn't complain about the entire chastity belt thing should be obvious enough to say she is also into masochism. Gets into new heights in chapter 77, when she administered an enema at school... Given what this series is, it's definitively not for medical purposes.
• True Love is Exceptional: Aria has all sorts of sexual experiences (though it's debatable whether she's a virgin), and expresses a wide array of kinks and perversions, but she has shown interest in Takatoshi, a boy who has negligible kinks at all (or at least, the kinks common to boys his age).
• Twisting the Words: Every other thing she hears from almost everyone is twisted into a weird fetish statement in her mind. She can twist even the most mundane statements.
• Yamato Nadeshiko: If her perversions can be ignored, she would be a classical example of this.
• Yandere: Occasionally:
  • Tsuda tells the girls to keep their watchful eyes at a distance while he works on his article. Aria then suggests that they do the staring like creepy stalkers from a partially-opened door, which creeps the living daylights out of Tsuda.
  • She does it again in Chapter 157.
• Yaoi Fangirl: It's mentioned that she likes yaoi magazines and novels.

Suzu Hagimura

Voiced by: Sayuri Yahagi

Ousai Student Council Treasurer.
A returnee student with an IQ of 180.
Fluent in English and can do 10-digit calculations in her head with ease.
This genius girl may look like a child, but is actually a high schooler.
If you mention her height, she gets pissed.
Sometimes a tsundere.
"Don't call me a child!!"

-Ranko's candid and unbiased description of Suzu (Chapter 150.5)

A first-year genius returning student and Student Council Treasurer. Despite being the more mentally mature girl of the main cast, she has a huge complex regarding her short stature. She's also somewhat superstitious, being terrified of ghosts.

---

• The Ace: She's the very best student of her grade.
• A-Cup Angst: Combined with being short, having the body of a little girl is a constant source of frustration for Suzu. She even has a dream sequence (used as a gag at one point) about hitting a growth spurt and becoming tall and busty.
• Affectionate Nickname: Uomi refers to her as "Suzupon".
• All for Nothing: In spite of all her huffing and puffing, it's shown that no one she's friends with particularly mind her small size, her childishness or her cuteness. If anything, she's loved for it.
• Berserk Button: Go ahead, call her a "little kid". She will cuss you out liberally in whatever language you referred to her as "little".
• Best Friend:
  • With Nene, in spite of her many, many kinks.
  • With Taka. Out of all the student council girls, Suzu is the closest to him, and hangs out with him the most.
• Cannot Spit It Out: She does show signs of liking Takatoshi, but never acts on it much, aside from getting jealous when other girls try to get close to him, such as Uomi.
  • This has been used for Bait-and-Switch gags, such as the time she's portrayed as sneaking into Takatoshi's tent and tearfully telling him, "I can't hold back any longer!"... only to reveal she desperately needed someone to accompany her to the outdoor toilet.
• Can't Hold His Liquor: She gets tipsy just from the smell of alcohol. Partially justified due to how small she is.
• Character Catchphrase: "And if I told you I'm a returning genius with an IQ of 180 who can speak 7 languages and make 10 digit calculations in my sleep, would you still say that I look like a little girl?!" (This is, of course, usually replied to with a "Yes.")
• Clingy Jealous Girl: Like Shino, she is less than pleased when Uomi starts becoming closer to Takatoshi, such as the first half of episode 13/season 2.
• Compliment Fishing:
  • Suzu tends to make questions that would be answered by the statement "because you're tiny", forcing her friends to try to avoid the subject. This is partly due to denial, due to her height complex, and also because she simply doesn't notice.
  • In Chapter 6, Suzu gives a thinly-veiled self-assessment of how people may take her attitude, and Takatoshi has to hold his tongue to not sound snarky:
    Suzu: Everyone who seems really mature usually has a childish side. People think it's pretty charming. On the other hand, when a childish person takes on an adult attitude, people will think that you're awfully impudent. Don't you?
    Taka: Not really. Recently anyway.
• Curtains Match the Window: Her hair and eyes are chalky yellow.
• Cuteness Proximity: This happens to her anytime Uomi is around, who simply can't resist hugging her.
• The Cutie: One of her main graces, much to her chagrin. She's like a cute little doll.
• Flanderization: The anime made her considerably more reactionary and short-fused than how she is in the manga, being one of the calmer and more collected characters in the original work.
• Funbag Airbag: When she bumps into Aria due to her size.
• Girlish Pigtails: Emphasizing her naivety.
• Gratuitous English: When she points the way to the station to a foreigner in the first few episodes, including a barrage of expletives when she was called "little girl".
• Height Angst: Her short stature happens to be her Berserk Button and occasional trigger; she actively avoids doing things that would remind herself of her physique.
• Heroic Self-Deprecation: She considers her own size a tremendous handicap in her affections towards Takatoshi in spite of being just as beautiful as both Shino and Aria. However, she doesn't realize that such notion is completely unwarranted.
• Hidden Depths:
  • Suzu is a very affectionate girl, and craves affection herself.
  • Suzu is surprisingly fit and resilient, having great physical endurance.
  • It's implied that Suzu is the main reason Taka and Kotomi are at least academically competent, as she frequently tutors them (more frequently than Shino and Aria). She has stated that tutoring them helps her with her own studies in the first place.
• Hypocritical Humor: Suzu, who despises being called a child because of her height, occasionally can't help but do things a child would do, such as building sandcastles and taking afternoon naps.
• Insufferable Genius: On occasion.
• Irony:
  • Out of all the girls surrounding Takatoshi, Suzu is the one who is more likely to end up in an embarrassing situation with him, all in spite of her being the girl who'd least try such a thing.
  • Suzu is a better, kinder and more doting friend to Takatoshi than either Shino or Aria; in spite of this, she unwarrantedly considers herself lagging behind them just because she's smaller and less buxom than them.
• Lovable Coward: Suzu is bad with horror and ghost stories, which sends her into Suspiciously Specific Denial tirades.
• The Napoleon: She absolutely hates her short height, and the jokes others make because of it; this is amplified in the anime.
• Nice Girl: In the manga, Suzu is one of the few girls Takatoshi knows that doesn't treat him like an object of desire or like a Hormone-Addled Teenager.
• Not So Above It All:
  • She sometimes uses her size to get out of situations she dislikes, like evaluating a haunted house during the Cultural Festival, with the excuse that she's not tall enough to see the whole thing; of course, it doesn't work for her.
  • In later chapters, she shows craftiness at keeping close to Tsuda's side, such as having him give her a piggyback ride to purportedly fix his hands-in-pockets habit.
  • Suzu spends the entirety of chapter 281 mad at Tsuda because he didn't notice he touched Suzu's breasts (for context, he was catching her from a fall).
  • In one chapter, she complains about Noa and Yoshi being all lovey-dovey, then cuddles up against Takatoshi (to make room on the bench for Shino and Aria, naturally).
  • In chapter 413 and 414, she takes advantage of being cast as the female lead opposite Takatoshi to hug him and make a love confession. For the art.
  • It's shown that on occasion, she doesn't quite mind being cuddled, head-patted or carried by her closest friends, especially Takatoshi.
  • In spite of her fear of the occult and overall dislike of horror, Suzu is surprisingly given to readily suscribe to the paranormal explanations regardless of the fact that she's a critical thinker. As such, she unwittingly falls into biases that predispose her to start to fear, and to exacerbate said fear. In layman terms, she'd start thinking of ghosts even before trying to explain the phenomena at hand critically.
• Older Than They Look: Often mistaken for a child.
• Only Sane Woman: Of the main trio of girls. Granted that's not saying much but still...
• Oxymoronic Being: Suzu is at the same time the most mature and the most childlike character in the whole manga.
• Pint-Sized Kid: Played with. To say that Suzu is "tiny" is an understatement, though it varies depending on the particular panels. Standing, she reaches Tsuda at the waist, and Aria and Shino at the chest. Tsuda is taller than her even when he's sitting down, and she sometimes only can reach eye height when standing in front of the table at the student council room. To put it in perspective, she's a little taller than an average doorknob in a door (~4 ft or ~1.22 m tall), though this fluctuates. For instance, in Chapter 180, it's unclear whether she'd be able to ride a roller coaster with a 130 cm height restriction, implying that she might be shorter than that indeed. In later chapters, she writes her height as 140-146 cm, though it's implied in that strip that she's pushing it in the first place.
• Pint-Sized Powerhouse: She can do painful roundhouse kicks and outrun people twice her size.
• Platonic Life-Partners: With Takatoshi, on account of both of them being first-years (later second-years) and paragons of sanity in the Student Council. Out of the Student Council, they're the closest and spend quite a bit of time together (partially thanks to the fact they're classmates). Suzu is also one of the few girls at school who doesn't treat Taka like a chronic masturbator, and it's shown that she greatly cherishes his friendship.
  • As mentioned above in entries above, however, Suzu is increasingly hoping their relationship takes a romantic turn, and becomes bashful and flattered whenever the possibility of her being with him is brought up.
• Puppy Love: Played with. Contrary to most of the girls in the manga, Suzu's attraction to Takatoshi is very tender and sweet, as if she were a little girl in love, as it's shown that she cherishes every moment and interaction she spends with him.
• The Reliable One: As her grade's The Ace, Suzu is a considerable asset for both the school and the Student Council.
• Repeat What You Just Said: She loves being referred to as "Senpai" and sometimes she either pretends to ignore them or makes her underclassmen repeat themselves just to hear it again.
• Running Gag:
  • In the manga, Suzu is often only drawn from the eyes up (or less) to denote her height. Sometimes just a half-dome is drawn with a label [Suzu's head] underneath, or even not drawn at all and only labeled.
  • Suzu usually has to take measures not to pee herself in bed whenever she stays somewhere overnight.
  • There are several instances where the gags involve her either hugging or being carried by Takatoshi, to her delight.
  • Suzu frequently conks out by the late afternoon because she runs out of batteries, and periodically falls asleep in the Student Council room. This is one of the aspects that certainly doesn't help her efforts to be seen as a mature girl.
• Shorter Means Smarter: Just omit the "short" part.
• Spaghetti and Gondolas: Averted. She grew up in Italy but doesn't have any stereotypically Italian qualities, besides speaking English with a hilarious accent.
• Suspiciously Specific Denial: In Chapter 245, she immediately declares upon noticing that the Movie Research Society at school will be doing a horror project:
  Suzu: N-NOBODY WILL WET HERSELF!!
• Straight Man: She takes this role whenever Takatoshi is absent. Otherwise, she and Takatoshi usually play a tandem role.
  • On the other hand, when her height or scary things are involved, she often devolves into a Boke like Shino and Aria. Anything to do with Takatoshi in a romantic sense can also trigger this reaction.
• Sweet Tooth: In Chapter 77, Suzu gives away her weak willpower towards sweets:
  Suzu: (...) However, it is a known fact that sweets stimulate the brain. Glucose is the energy source of the brain after all. Daily intake could affect our academic performance. (starts drooling) And so, I ask that we make an exception for the greater cause.
  Taka: You just like cake.
• Teen Genius: Has an IQ of 180.
• Tsundere: Aria refers to her as one. She even somehow convinces her to give the stereotypical 'It's not like I made these specially for you, it's just an obligation' type line... but Tsuda doesn't understand tsunderes, so he just gets depressed. However (at least in the manga) she's a more collected person than what the trope suggests.
  • As the series goes on, this is played straight more often. For example, when Kotomi teasingly asks if the fact she will start walking to school with Takatoshi intrude on Suzu's private time with him, Suzu grumpily denies it while blushing and looking away.
• Weaksauce Weakness: In Chapter 451, Koyama-sensei notices that Takatoshi paying attention to her (in this case noticing she looks different and asking if she'd gone to a beauty parlour) can shut her powerful mind down to the point she needs to use a calculator. As a reminder, Suzu can normally do 10 digit calculations in her head easily.
  • In Chapter 413, both Aria and Shino are impressed with Suzu's ability to memorise her audition lines in one go. However, they both notice and are puzzled by the observation that once Takatoshi is standing in front of her giving her lines like, "You're the one who's most important to me!" she falls apart and begins stuttering nervously.
• Weirdness Magnet: Because she's so serious, Suzu is the subject of the most sex jokes in the series behind Takatoshi, all at her expense and from completely innocent topics that she brings up.
• Why Did It Have to Be Snakes?: Anything horror related. She's so terrified of supernatural things that she once claimed she was too short to notice a haunted house, preferring to draw attention to her own Berserk Button than face the haunted house.
• Wise Beyond Her Years: She's easily the most intelligent character in the series and also has a wealth of general knowledge.
• You Are What You Hate: Suzu is childish and cutesy, which is the exact contrary of how she wants to portray herself.
• Your Size May Vary: Her shortness tends to change depending on how much exaggeration of it is needed for a given joke. For comparison, her height generally seems to be between crotch to lower chest on Takatoshi.

Other Ousai Academy Students

Kotomi Tsuda

Voiced by: Asami Shimoda

Takatoshi's younger sister and a third-year junior-high student (and later a first-year at Ousai). Generally a sweet, caring girl, but also in possession a mindset that'd make Shino proud. Later in the story, she becomes the manager for the Judo Club.

---

• Affectionate Nickname: Uomi refers to her as "Koto-chan".
• Annoying Younger Sibling: Her perversions get on Takatoshi's nerves often. It only gets worse when he discovers she's been telling people details about him like his sexual interests, or when she photoshopped his head onto a Brazillian carnival dancer as her self-study project, and put it on display.
• Asleep in Class: Seems to have this problem, if her "New Year's resolution" of stopping that in Chapter 68 is of any indication.
• Attention Deficit... Ooh, Shiny!: It's shown that Kotomi has concentration problems, as in Chapter 392, she'd mishear even beneficial advice given right to her face.
• Big Brother Attraction: She likes invoking Brother–Sister Incest (especially in the yonkoma), Season 1, Episode 12 has her admitting that she had an incestuous dream, and a strip in the yonkoma also mentions that she and Tsuda sometimes get mistaken for a couple, which she plays up. When her friend notes that it's sometimes hard to believe they're related because of their very different personalities in Chapter 43, Kotomi gets excited and interprets the comment as a possibility that they might be Not Blood Siblings. She also has no problem taking her clothes off in front of her brother◊ and once proudly mentioned to the other girls that he's also "impressive down there", which has him wondering as to when the hell she managed to sneak a peek. In the fourth OVA she becomes very, very pleased when Shino points out that she and Takatoshi being alone for the weekend while their parents are on a trip sounds like the setting of an eroge. And when she's imagining having lewd words written on her body, it says "Taka's *** exclusive use"
• Book Dumb: Even more so than Takatoshi—she probably wouldn't have gotten into Ousai at all had she not been interviewed by Yokoshima.
• Character Catchphrase: Cowgirl! ^note referring to the sex position (Usually said out of nowhere.)
• Chuunibyou:
  • Invoked by Takatoshi in Chapter 182:
  Taka: (Thinking) Why does everything she says sound like it's from a shounen manga?
  • In Chapter 271, she actually attempted to establish a club for "armoured fighting," because she found the armoured characters in video games cool. This is lampshaded in S2E10 in Dejima's imagination, seeing her as a "chuuni JK". There's also numerous hints in the manga suggesting that she was indeed a chuuni in middle school.
• Covert Pervert: Initially. Later she's as openly perverted as Shino.
• Curb-Stomp Battle: She once issued a dojo challenge to Mitsuba. This in no way implies any martial arts ability.
• Cute Clumsy Girl: Invokes this herself for her own amusement.
• The Ditz: Really lacking in the intellectual department.
• Everyone's Baby Sister: For the Student Council, and later quite more literally, for Uomi.
• Expy: Unbelievable as it may seem, she's actually a less perverted expy of the titular sister from another of the author's previous manga, Imouto wa Shishunki.
• Fanservice Pack: In the second season she gets noticeably larger breasts which are sometimes used for gags. Justified in that she's going through puberty.
• Gamer Chick: Seems to fall into this occasionally.
• Genki Girl
• Girlish Pigtails: For her naivety.
• Hidden Depths: Beyond her perversions and kooky behavior, it's shown that Kotomi thoroughly enjoys being pampered by her brother, and is very receptive to his affections.
• Little Sister Heroine: Lampshaded in the intro◊ of the third (post-Season 2) OVA where she and almost every of her brother's Love Interests are wearing wedding dresses and holding a bridal bouquet each, while an increasingly weirded-out Takatoshi asks in the background why is Kotomi there given the obvious symbolism of the scene.
• Nice Girl: For all her perversions, she is a genuinely nice girl. Pity her values system is so screwed up.
• Red Oni, Blue Oni: The red to Toki's blue.

Ranko Hata

Voiced by: Satomi Arai

President of the Newspaper Club, who spends most of her time taking pictures of the Student Council, and trying to uncover dirt on them.

---

• All for Nothing: For all her effort, surveillance and smear journalism, she has yet to obtain a headline that she didn't make up or overblew on her own. In spite of the salacious conversations in the student council due to Aria and Shino, hardly anything actually ever happens in there.
• Bad Liar: Hata's excuses are always paper-thin, and she's tremendously prone to giving herself away whenever she tries to do salacious stuff.
• "Blackmail" Is Such an Ugly Word: Played for Laughs and played with. Hata repeatedly tries to pull this off with salacious pictures and libelous stories, but she's not conniving enough and she's too sincere to get away with it. She's essentially powerless to the student council's authority, who constantly foil her.
• Blatant Lies: She totally doesn't own all the camera equipment they found during the school trip to Kyoto.
• Camera Fiend: She embodies the trope so well that she's the page image.
• Character Catchphrase:
  • "This will sell!"
  • She also says "Shutter Chance!" whenever she sees a potential hot scoop (usually involving the student council).
  • And she normally says "Hata here, from the newspaper club." when she enters a room.
• Covert Pervert: Whenever she conducts interviews, she changes the wording for innuendo-filled wording.
• Crazy-Prepared — She brought a souped up digital camera, zoom lens, pan lens, and a bunch of other lenses, about a dozen bags of other equipment, a sound collector, a TV camera, and a motion capture camera, just to get a scoop of Shino during their trip to Kyoto. It was revealed that after Aria deleted the pictures that the identity card in the camera is a decoy.
  • She also carries a small bag containing an umbrella, a waterproof jacket, some food rations and a bottle for urinating. She takes her job really seriously.
• Creepy Monotone: ...Which sets her apart from the other, hyperactive girls.
  • That said, she sometimes engages in a bit of mad laughter when something particularly amuses her, as seen during the Squid and Takatoshi segments of the second anime.
• Deadpan Snarker: She can make these sorts of comments at times towards the student council.
  • As an example, when the student council finds a photo album, they try to find out who owns it by looking through the photos. When they find a cutting board labelled "President and Hagimura-san", they immediately realise whose book it is. Shino immediately decides to have a word with her.
• Deranged Animation: Just to highlight her weirdness more, she was often deliberately animated in extremely bizarre ways that make her almost seem like a Humanoid Abomination. One time, a "Hmmmmmm?" question from her was accompanied by her character physically enlarging so that her face fills up half the screen, complete with visible image compressions.
• Emotionless Girl: Subverted. While she has many of the iconic qualities of one (blank stare, monotone voice, generally creepy attitude) Hata is clearly fully capable of experiencing (and often exhibits, sometimes to great extremes) as great a variety of emotions as the other characters. She's just terrible at expressing them. When asked to smile, she does so by taping the sides of her mouth to her cheeks.
• Gossipy Hens: On occasion, especially with Shino and Aria.
• Large Ham: A rather strange example as she carries the qualities of an Emotionless Girl, but is perfectly capable of being hammy.
• Loophole Abuse: As per their agreement, she kept her mouth shut about finding Shino and Takatoshi spending the night together in an inn. She simply showed the disciplinary committee the pictures she took.
• Mundane Made Awesome: Hata setting up a camera tripod with high-intensity zoom like a sniper rifle.
• No Sense of Personal Space: She tends to get uncomfortably close to other people, particularly when interviewing them.
• Non-Standard Character Design: She is definitely the only one missing a visible nose in the entire cast and is the only one without glossy eyes. She also frequently lacks a mouth and is rendered as a chibi more often.
• The Noseless: While she has one in profile, she's normally shown without one when viewed from the front.
• Not So Above It All:
  • Is not above acting flirty with Takatoshi to get what she wants. She was also unusually embarrassed when Takatoshi hinted he was interested in her (he was actually saying he always keeps an eye on her due to her tendency to twist words in her hunt for scoops).
  • Albeit it's shown that she's fishing for scoops and scandals, it's implied that she likes messing with people to make them embarrassed.
• Offscreen Teleportation: Sometimes engages in this. The finest example was when the student council were watching her, and when they turned to leave she was standing right behind them. Suzu and Takatoshi scream in horror.
• Only in It for the Money: As her catch phrase would illustrate.
• Open Mouth, Insert Foot: Because of her straightforwardness, she has a habit of incriminating herself whenever she talks with the student council, causing the frequent confiscation of her cameras and material.
• The Peeping Tom: About 75% of the time she secretly films the Student Council at their room, she's expecting for something saucy to happen, and not for the headlines to say the least. To her frustration, they're more subdued than she'd ever hope for, and she's almost always caught anyway.
• Perpetual Frowner - The only time she ever smiles is with the assistance of two pieces of tape.
• School Newspaper News Hound: She spends most of her time scooping for scandals.
• Shipper on Deck: Played with. For Takatoshi/Shino in the later strips, and she spreads the rumor about them being together for the sake of a juicy, scandalous story. However, she is more than happy to take advantage of any situation that crops up. For example, when Uomi publicly addresses Takatoshi as "Taka-kun" (her pet nickname for him), she's right there with the rest of the school, eagerly watching. When Mori-san is introduced, she quickly picks up on how easily the two get along and keeps an eye on them.
• Stalker without a Crush: She follows the student council around (especially Shino and Tsuda) only to get an interesting scoop.
• Twisting the Words: One of the things she likes doing is altering whatever statements she hears (usually from Takatoshi) to make it sound more perverted. It's apparently her belief as a member of the mass media.
• Verbal Tic: "Shutter Chance!" (before taking a shot)

Mutsumi Mitsuba

Voiced by: Chiaki Omigawa

President of the Judo Club and classmate of Takatoshi, for whom she has a pretty obvious crush.

Innocent and earnest to a fault, Mutsumi is an incredibly athletic tomboy.

---

• Aborted Declaration of Love: Seventh OVA. Complete with Last-Second Word Swap.
  —"I really love...making sweets."
• Action Girl: Second dan black belt in Judo and is generally competent in that. In her first appearance she stated that she originally wanted it to be a Muay Thai club but chose judo as it would attract more members.
• Alliterative Name
• Big Eater: Justified for being an action girl. A strip in Chapter 232 discussed that; she kept her tournament food expenses low by... fulfilling "big eater challenges" at restaurants. Yet, she's hardly fat, she burns it all off quickly.
• Bodyguard Crush: When Hata mentions that Takatoshi is being targeted (romantically), Mutsumi misunderstands and declares herself Takatoshi's bodyguard.
• Cannot Spit It Out: Really likes Takatoshi, but never clarifies... much to Chiri's consternation.
• Cloudcuckoolander: For her near lack of sexual knowledge.
• Club President: Of Ousai's judo team.
• Covert Pervert: Not even she's immune to it. In one gag, she's just returned from judo practice and is sweating profusely when Takatoshi asks her for help hanging something on the wall, requiring her to get close to him. When she blushes and says that she can't because she's covered in sweat, Takatoshi says he doesn't mind. Her eyes instantly light up and she excitedly asks "Is that your fetish?!"
• Cute Bruiser: She can wipe the floor with virtually any other character in the series (barring perhaps her teacher Daimon-sensei). This sometimes causes her some angst, however, as she sometimes wonders if she should be more frail and girlish.
• Does Not Know Her Own Strength: Inadvertently paralyses Tsuda when she hits a vital spot when playfully poking him.
• His Own Worst Enemy: Albeit Mitsuba likes Takatoshi, she lacks both the courage and the acumen to pursue him romantically. As such, her innocence gets the better of her and completely nullifies her drive.
• The Ingenue: Well, most of the time. Any advice Shino gives her contains sexual innuendo, but she always takes them literally. She's so pure that when she says her dream is to be a bride, the radiance blinds everyone present. Everything that is said to her, she gives the benefit of the doubt, and even deems that it warrants discussion, notwithstanding how outrageous the subject is.
• Innocent Innuendo: Is especially prone to this. Among other things, she once asked Takatoshi if she could hold on to him "down there" (she wanted to hold on to the back of his shirt during a courage test), turned over a porn mag she confiscated from her Judo Club members with a hearty, "Please accept this!" and invited the Student Council to join the Judo Club for a trip to a skating rink by saying, "Would you like to go out tomorrow?" to Takatoshi.
• Modesty Shorts: She wears bike shorts under her skirt, which apparently gives her the impression exposing these is entirely unproblematic, which causes Suzu to remind her to sit in a more ladylike manner in chapter 230.
• Nice Girl: Stands out as one of the few female students with little or no perversions.
• Passionate Sports Girl: She is a judoka committed to her martial art to the core.
• Oblivious to Love: She clearly likes Takatoshi, and even feels sad or jealous when she sees him getting along with other girls, but she still hasn't figured out just what she's feeling.
• Throw the Dog a Bone: While acting as Takatoshi's bodyguard, the two walk home together under the cherry trees the way a couple would.
• Tomboy and Girly Girl: The girly girl to Chiri's tomboy, at least in terms of attitude.
• Tomboy with a Girly Streak: She's tomboyish and sporty, but she has the heart of a maiden.
• Tomboyish Ponytail: On occasion, though she alternates it with Girlish Pigtails.
• Unknowingly in Love: Is obviously absolutely smitten by protagonist Takatoshi Tsuda, but due to her pure and innocent nature doesn't connect the dots that what she feels is romantic love (to the frustration of her best friend Chiri and members of their Judo Club). It's notable that the other members of Takatoshi's Unwanted Harem never raise their guard around her (unlike with other girls like Uomi or Mori), since she's so oblivious to her own feelings they don't feel threatened at all despite her closeness to Takatoshi.
• Unknown Rival: To Shino and to herself. Neither of them is aware of the other's attraction towards Taka, and she herself is not aware of her own feelings.
• Yamato Nadeshiko: Her goal.

Chiri Nakazato

Voiced by: Yukika Teramoto

Mutsumi's tomboyish friend and another member of the Judo Club. Most often than not, the victim of Mutsumi's crazy training routines.

---

• Boyish Short Hair
• Covert Pervert: Mutsumi finds her and the other girls flipping through a porn magazine in Chapter 318.
• Satellite Character: She really only appears when Mitsuba and the rest of the Judo club does.
• Shipper on Deck: For Tsuda and Mitsuba, along with the rest of the Judo Club. She often tries to hint to Mitsuba about what it is she's feeling but it never quite gets through.
• Straight Man: Made apparent in the fourth OVA Festival Episode.
• Tomboy and Girly Girl: The tomboy to Mutsumi's girly girl, at least in terms of attitude.

Kaede Igarashi

Voiced by: Emiri Katou

The high-strung, androphobic head of the Disciplinary Committee as well as head of the Choir Club. As the series progresses, she lightens up and is even able to have genuinely friendly conversations with Takatoshi. She spends a lot of her time fainting from the outrageous topics Shino and Aria bring out in her presence.

---

• Clingy Jealous Girl: Sometimes has shades of this, such as the time Uomi (who was taking Shino's place as Student Council President as part of an exchange programme) clung to Takatoshi to discuss something during a meeting. While she had an argument (that was much too touchy-feely to be appropriate at school), she had already seemed annoyed by Uomi casually talking to Takatoshi and addressing him as "Taka-kun".
• Covert Pervert: For all her prudishness, she immediately mistakes a perfectly innocent discussion on sleeping posture in chapter 120 as proof that the student council knows each other's sleeping postures because they have slept together. Shino and Aria call her out on this.
  • In chapter 199, she misinterprets assurance that Tsuda didn't sleep next to the girls on their trip, as him having sex with them all night round.
• Does Not Like Men: Unlike most examples of this trope, it's played entirely for laughs.
• Girlish Pigtails
• Hope Spot: Played for comedy. In the last episode, Tsuda catches her by the hand with no negative reactions. While the student council celebrates the breakthrough, it's soon revealed that Kaede has only gotten used to Tsuda.
• Irony: For all her androphobia, Kaede is the only girl in the story who has technically gone on a date with Tsuda. She does this in order to keep an eye on Nao and Yoshi, who were going on a date themselves.
• Nice Girl: She is, by far, the most innocent and well-intentioned character in the story.
• Not So Above It All: While on a (pretend) double date with Takatoshi to keep an eye on Noa and Yoshi, Kaede scolds the Sickening Sweethearts for going too fast and risking getting separated from her and Takatoshi. Noa begins to apologise, thinking Kaede is scolding them for trying to ditch her and Takatoshi, but Kaede pulls out a pamphlet and tells them that in order to get on as many rides as possible, they can't waste any time.
• Reasonable Authority Figure: Several strips have her struggling with how far she should push the school's no-dating rules, not wanting to be seen as too unreasonable.
  • When faced with the school's no. 1 couple cuddling and Shino molesting Aria's breasts, she judges that the latter is far, far worse and goes to deal with it first.
• Ship Tease: Later chapters where she's gotten more used to Takatoshi's presence will also sometimes tease a possible infatuation with him. The uber example would be Episode 12 of Season 2, where Takatoshi saves her from falling down the stairs and it's revealed she's alright with physical contact with him. Shino and Suzu are wary of the development.
  • Unusually, both Takatoshi and Kaede seem aware of this in-universe. Takatoshi, for example, quickly realises how it looks when Kaede blushes and runs away squealing, "I talked to him!" Several chapters have punchlines where Kaede has Not What It Looks Like moments wherein she belatedly realises her actions or the situation make it look like she's interested in Takatoshi.
  • In Chapter 305, she asks Takatoshi if she can sit next to him as it's the only seat available. The moment she sits down, everyone else at the table get up and walk away, leaving the two of them alone. Takatoshi wryly observes "Just as she sits down..." while Kaede herself realises this makes it look like she deliberately wanted to sit next to him.
  • In Chapter 324, Kaede is asked by her older sister to get her a pair of men's underwear for security reasons (her sister lives alone, and the idea is that if potential criminals see male underwear hanging out to dry they won't suspect there's a single woman living in the flat alone). Naturally the Student Council goes along, and Takatoshi offers to take the underwear to the cashier while the rest of the Council go to a different section, leaving him and Kaede alone. Kaede tells him she isn't a child and can do it herself, but allows him to escort her. Just as the cashier is ringing up her purchase, Kaede suddenly realises that the situation looks like a boy and girl going underwear shopping together, and hurriedly (and loudly) pretends to be Takatoshi's older sister. She even forcefully smothers a potential Love Epiphany.
  • In Chapter 364, where Takatoshi accidentally gets adhesive on his hand. A worried Kaede grabs his hand, and as a result they're stuck together. They spend the rest of the chapter holding hands awkwardly while trying to keep it secret (though it inevitably gets out). Takatoshi tries to apologise for what he assumes to be a traumatic memory, but Kaede assures him she didn't find the experience all that bad.
  • In Chapter 470 Takatoshi and Kaede go on a Not a Date to an amusement park in order to chaperone Noa and Yoshi (to make sure the Sickening Sweethearts don't get carried away). They actually seem to be enjoying themselves, and Kaede even wipes Takatoshi's face when he gets cream on it during lunch. Both Noa and Dejima (who happens to be helping out at the amusement park) tease Kaede about how well she and Takatoshi seem to be doing.
  • Kaede and Takatoshi actually do get along quite well whenever Kaede's "hates men" tendencies don't get in the way. Takatoshi genuinely respects and admires her (though he also finds her a bit of a drama queen).
• Single-Target Sexuality: Played with. If she needs a guy's opinion or help, she immediately goes to Takatoshi. She's far more comfortable around him than she is even the male members of her own Disciplinary Committee.
  • When some of her Choir Club members discuss wanting to recruit boys into the club in order to increase the range of notes the club can reach, Kaede goes to see Takatoshi and does her best to convince him to at least give it a try. Unfortunately, her choice of words and the situation make it look like she's trying to ask him out instead.
• Sour Prudes: Much of her dislike of those breaking the school's "no dating" rules come from her own insecurities.
• Straight Man: One of the few sane people and during the second year in season two trip she panics after realizing that both Takatoshi and Suzu are gone leaving her alone to deal with Shino, Aria and Kotomi.
• Tsundere: At the end of Chapter 364, Kaede reacts this way towards Takatoshi, telling him that being stuck to him wasn't completely bad.

Nene Todoroki

Voiced by: Hekiru Shiina

Suzu's friend and member of the Robot Research Club for the purpose of more stimulation.

---

• Gadgeteer Genius: Although only for improving her orgasms.
  • She is, however, genuinely talented. Her robot dog, for example, is quite lifelike in its movements.
• Hidden Depths: Even when she's outrageous most of the time, she's Suzu's close friend, implying that there's aspects of her beyond the kinky stuff.
• Horny Scientist:
  • A rare female example, she's portrayed in a continuous state of arousal given the fact that she seems to always have a dildo sticking up her nether regions, although she hides it well.
  • In later chapters, she doesn't even bother hiding it and freely admits whenever she has something in there. Which is almost all the time.
• Let's Get Dangerous!: Takatoshi is impressed when he sees her during a robot competition, as she is totally focused and in control.
• Lovable Sex Maniac: Her Robot Research Club is more sex toys development than actual robot research. And she is the principal test subject!
• Robosexual: Uses her membership in the Robot Research Club as an excuse to create various vibrators. She has also expressed the desire to eventually build a sexbot of some sort.
• Too Much Information: About every time she interacts with Suzu. Girl's not shy about her sex toys.

Kaoru Toki

Voiced by: Miho Hino

Kotomi's first friend at Ousai Academy. Has the look of a delinquent, but isn't much of one. She later joins the Judo Club after being defeated by Mutsumi in a match.

She's generally known by her nickname Tokki.

---

• Cute Clumsy Girl: Her actual defining characteristic. She's the kind of girl who routinely showers wearing socks so that she doesn't slip, or put on a blouse without drying herself from a shower, only to realize that adding insult to injury, it isn't even her blouse...
• Deadpan Snarker: She's arguably the only one of the cast who comes close to Takatoshi's level.
• Defeat Means Friendship: Joins the Judo club after losing to Mutsumi.
• Face of a Thug: She's actually more of a Cute Clumsy Girl.
• In-Series Nickname: Tokki, as mentioned above.
• Japanese Delinquents: Subverted. She looks the part, certainly, but she's considerate of other people and has been shown to actually put effort into her studies (unlike Kotomi).
• Lady Looks Like a Dude: With her height, sharp eyes and surly attitude, one can easily imagine her passing as a boy with the right clothing.
• Nice Girl: One of the calmest and most collected characters in the story, in spite of being a constant little mess all the time.
• No Sense of Direction: As a result, she's always late when she plans to visit the Tsuda household. It also results in her getting lost more often than not, even during jogs with the rest of the Judo Club.
• Not So Stoic: In chapter 453, she is quickly defeated during a match against Seikou Girl's Academy's judo club. She quickly hides her eyes behind her bangs, but Kotomi realises she's shaking with barely restrained tears of frustration.
  • This is especially bitter for her because she was able to match Mutsumi when she was recruited into the club, and she's generally considered one of their best players.
• Only One Name: Following the reveal of the Eiryou Student Council's first names (Chihiro Uomi, Nozomi Mori and Toori Aoba), Tokki is now the only side character whose first name is unrevealed.
  • The Movie's trailer reveals her full name is Kaoru Toki.
• Only Sane Man: One of the only female characters without any perverted thoughts thus far in the series.
• Red Oni, Blue Oni: The blue to Kotomi's red.
• Satellite Character: She's the only character who hasn't interacted with Takatoshi one-to-one, as she normally appears alongside Kotomi or the Judo Club. And even as a member of the Judo Club, Takatoshi is normally speaking to Mutsumi.
  • They finally have a conversation between just the two of them in chapter 454. Alas, when she complains she feels tired Takatoshi offers to give her a massage and inevitably Kotomi wakes up to hear...
  (Takatoshi smiling with satisfaction and Tokki lying face down)
  Takatoshi: How was it?
  Tokki (revealing a flushed face): Yeah, that was amazing. You're really good, Onii-san.
• Silent Snarker: Unlike Takatoshi or Suzu, Tokki either keeps her snarking to herself or does so in a dry, quiet manner.
• Stealth Pun: She's a rebel without a sense of direction.
• Straight Man: One of the few sane people in the series and generally plays this role against Kotomi or Shino.
• Surrounded by Idiots: She sometimes gives off this vibe when confronted with the craziness of Kotomi and the Student Council.
• You Are in Command Now: When Mutsumi and the Second Year students go on their school trip in Season 2, Tokki is put in charge of the Judo Club.

Kenji Yanagimoto

Voiced by: Minoru Shiraishi

Takatoshi's best friend and classmate.

---

• All Men Are Perverts: He is hinted at as being one of the boys who applied to Ousai hoping to find himself a harem, or at least a girlfriend.
• Butt-Monkey: Twice over the course of the SYD anime Kenji has been seen all gussied up for Valentine's Day hoping to receive chocolate, and both times he's been disappointed.
• Hidden Depths: He turns out to be a member of the Ousai Film Club, and in chapters 413 and 414 manages to recruit the Ousai Student Council to help with a film the club is working on. Kenji himself is the director. Later chapters reveal the film actually wins an award.
• Pair the Spares: In the Japanese fandom, he's often paired up with Chiri.
• Straight Man: Sometimes falls into this role, especially when no one from the Student Council is around.
• Throw the Dog a Bone: Chiri casually hands him a half-open (and half-eaten) box of Pocky on Valentines Day while chatting with their classmates, and Kenji gratefully accepts.

Nao Hanamaki and Yoshi Umakawa

Collectively known as "Ousai's first idiot couple", Nao and Yoshi are a pair of high school sweethearts mostly used as a setup for gags.

---

• The Ditz: Chapter 347 describes them as "Ousai's first idiot couple".
  • The term "Bakaple" is actually a reference to them being Sickening Sweethearts. That said, the Student Council isn't sure how to respond when Nao tells them she wants to confess her feelings to Yoshi. They can only (internally) blurt out, "You're only doing that now?!"
• Only One Name: During the majority of the manga, they've been referred to by their given names, and their family names wouldn't be revealed until an omake in Volume 17. They actually thank Kaede for saying those out loud after so many years.
• O.O.C. Is Serious Business: The Student Council find it odd to find them arguing in one strip. They quickly make up, though...by making out.
• Satellite Character: Their purpose in the manga is essentially to be scolded by Kaede for flirting, then have Shino disagree and encourage them to take it up to adult levels.
  • Averted slightly with Nao. Outside of this, she is head of the Film Club.
  • Chapter 468 and 469 reveal quite a few things about Nao. She's close enough friends with Kaede to share her plans to go out on a date with Yoshi at an amusement park during the Golden Week holidays, she's familiar enough with Takatoshi to address him as "Tsuda-kun" (as opposed to "Vice-President") and she seems to be a Shipper on Deck regarding Kaede and Takatoshi.
• Shipper on Deck: In Chapter 468 she suggests Kaede come along with her and Yoshi on their date to an amusement park to keep an eye on them, and when Kaede protests she'd be a third wheel Nao quickly asks Takatoshi if he'd like to go on a double date (herself and Yoshi, him and Kaede).
  • In Chapter 469 she teases Kaede for wiping some cream off Takatoshi's face during lunch, pointing out that the two of them seem pretty close. Kaede responds by demanding to know why she and Yoshi have lipstick smeared around their faces.
• Sickening Sweethearts: Officially that couple.

Polly Copelin

An American transfer student who first appears in Chapter 474 as part of a program where she'll spend one year as a second-year student at Ousai Academy. An airhead with limited Japanese skills, she becomes a classmate of Tsuda, Suzu, Mitsuba and Nene. Polly also unsuccessfully runs for the student council presidency and later joins the morals committee and is a junior member under the supervision of Kaede.

---

• Cloud Cuckoolander: As stated on Hidden Depths, she tends to arrive to hilariously bad conclusions about Japanese culture, such as taking the popular folklore story Tsuru no Ongaeshi as the Japanese delving in bestiality.
• Cuddle Bug: It's implied that she intended to illustrate that Americans are more effusive when greeting someone, using skinship, but Aria, Shino and Suzu stop her before she gets too close to Tsuda.
• The Ditz: Of the morose kind, as she's not a Genki Girl like, for instance, Kotomi.
• First-Name Basis: Since her introduction, she's always referred to by her name by all of the cast.
• Hidden Depths: It's hinted that she may be more of a pervert than what it seems, as she has knowledge of certain Japanese misconceptions that she may have picked up from watching Japanese porn.
• Informed Attractiveness: In spite of being drawn rather similarly to the rest of the female cast, Polly is stated to be a very beautiful girl.
• New Transfer Student: As part of a 1-year program.
• Token White: Played with. She's the only Westerner in a Japanese cast, though Suzu is part-Italian.

Other Ousai Academy-related characters

Naruko Yokoshima

Voiced by: Yuu Kobayashi

A teacher and advisor of the Student Council. Otherwise, she spends more time chasing younger men (including her male students, but especially Takatoshi) than actually teaching.

---

• Abhorrent Admirer: The men she hits on usually find her to be this, not because she's unattractive, but because her personality is so outrageously lecherous that she scares them away.
• Authority in Name Only: Her attitude has led her to have respect from neither her colleagues nor her students. This implies that on top of having Skewed Priorities, she's also unreliable as hell.
• Bread, Eggs, Milk, Squick: A common pattern with her. She can turn every topic at hand disgusting. Albeit other characters in the series can turn things perverted, Naruko in particular takes the cake.
• Creepy Uncle: Gender-Inverted. Although, as far as we know, her nephew is oblivious.
• Desperately Craves Affection: Beyond her pervertedness, she is shown to be sorely lacking in the love department, and wants the more mundane and tender side of relationships too. That she's an unapologetic mess of kinks doesn't mean that she doesn't crave for love.
• The Dilbert Principle: In Chapter 504, the student council weighs the option of her becoming the advisor for the Yoga club, but since she's the student council's "advisor", she cannot manage another club. In reality, they convince her with this argument because they deem that they shouldn't inflict other clubs with her presence.
• Dude, Not Funny!: She once says something so foul and over the top that even Shino gets offended ^(!) She complained of having pubic hair stuck between her teeth:
  Shino: What is wrong with you?
• Gratuitous English: She's Ousai's English teacher though the only time we see her teaching it, she's reading nonsensical Engrish (from an erotic novel naturally).
• Handsome Lech: Gender-Inverted Version. She's conventionally attractive, but she's so disgustingly lecherous that she makes even male perverts uncomfortable.
• Hard-Drinking Party Girl
• Hidden Depths:
  • Sometimes she shows that she genuinely yearns for romantic love (Chapter 154), marriage and a family (Chapter 167).
  • Whenever she's not being a massive pervert, she's shown to be very playful and goofy.
• Hot Teacher: Played with. She's a very beautiful woman, but her mouth gets the better of her.
• Large Ham
• Lecherous Licking: Licks her lips when she's in the mood, or has sexual thoughts.
• Let's Get Dangerous!: When Suzu gets lost during the second year school trip, she takes charge and issues orders, including to the other teachers.
• Lovable Sex Maniac: And she's the alpha female in a school full of perverse girls.
• Mrs. Robinson: She has stated that she has a preference for high school boys.
• No-Respect Guy: Thanks to her perversions.
• Odd Friendship: With Koyama-sensei. Both of them hang out together for drinks and bond over being single, but she drives Koyama to her wits' end with her dirty mouth and perversions.
• O.O.C. Is Serious Business: She acts like a normal teacher whenever she's ill, which disturbs the main characters a lot.
• Open Mouth, Insert Foot: The main reason she is unable to gain the affection she so desperately craves. When she opens up her mouth, awful things come out.
• Really Gets Around: Implied Trope. She's so unabashedly sex-driven that it goes beyond Cloudcuckoolander levels. She's just too off-the-wall that it would be weirder for it not to be true.
• Sensei-chan: She's on her late 20's to early 30's and can pass off for a student if she puts on a uniform.
• Womanchild: To the point where Shino wonders why she's suddenly decided to act like a teacher after they finish cleaning out the abandoned room. Her voice even becomes extremely childish at times.
  • Aside from the perverted stuff, she'll occasionally engage in dumb stuff like pressing her nose against a window to make a pig face.
• Yaoi Fangirl: Reads the yaoi genre mags she confiscated with lots of Squee.

Sachiko Furuya

Voiced by: Fumi Hirano

Ousai alumni and Shino's predecessor as president of the Student Council. She's hilariously old-school, even beyond her age and even time of birth.

---

• Born in the Wrong Century: Her most prominent characteristic. Being Shino's predecessor, she's at most two years older than her. Yet she uses Japanese slang from The Eighties completely unironically and even her Fanservice is old fashioned. There are times when she even behaves like a grandma.
• Cool Big Sis: Acts like one to the current Student Council. Takatoshi and Suzu are both fond of her, since she's nowhere near as zany as Shino or Aria.
• Drop-In Character: Occasionally drops in to see her old school and friends, sometimes inviting them to university functions.
• Hotter and Sexier: Compared to her Ousai Academy days, she's more glamorous and stylish. Which makes sense, as she no longer has to wear a uniform or is restricted by school rules concerning hair colour, jewellery or makeup.
• Hopeless with Tech: Even worse than Shino. She's so bad with technology that she uses a pocket abacus instead of a calculator.
• Nice Girl: She's very doting and kind.
• Only One Name: While Furuya is her last name, her first name goes unmentioned.
  • Her first name (Sachiko) is finally revealed in Volume 17, Chapter 484.
• Pun: Her entire characterisation is built around the joke that another term for an alumni is "old girl/boy".
• Team Mom: For the Student Council, but more accurately, she'd be a team grandma.

Others

Rika Koyama

Voiced by:

A newly arrived teacher, she previously encountered Shino during her stint as a trainee and so remembers her quite well.

---

• Boke and Tsukkomi Routine: How interactions between her and Naruko tend to go.
• Cool Teacher: She's professional but also approachable.
• Odd Friendship: With Naruko. Both of them hang out together for drinks and bond over being single, but Naruko's dirty mouth and perversions tend to cause her to snap.

Daimon-sensei

Voiced by: Kentaro Tone

P.E. teacher and coach of the Ousai Academy Judo Club.

---

• May–December Romance: With Michishita-sensei. The Judo Club pokes fun at him for his engagement to such a younger woman.
• Ugly Guy, Hot Wife: Again, with Michishita-sensei. He's older and balding. She's youthful and attractive.

Eiryou High School Student Council

The Student Council of Eiryou High School are slowly introduced over the course of the series. They maintain an excellent working relationship with the Ousai Student Council, and have forged friendships outside of school as well.

---

• Foil: To each of the Ousai Student Council members. Uomi is calm and controlled where Shino is dramatic and excitable. Mori and Takatoshi are Distaff Counterparts of each other. Aoba is very much a face in the crowd whereas Aria grabs attention wherever she goes. And Yuu absolutely towers over Suzu (heck, Yuu is actually slightly taller than Takatoshi!).
• Three Plus Two: They were a team of three at least until chapter #415, where Uomi recruits Yuu as the fourth member of the Council.

Chihiro Uomi

Voiced by: Chiwa Saitō

Shino's counterpart from Eiryou High School and a third-year student. Uomi is a deadpan girl who has the same sense of humor as Shino, but happens to be more doting and more voluptuous. She's very prone to hugging people, and due to their shared interests and circumstances, Uomi and Shino become close friends, and later establish a Friendly Rivalry for Tsuda's affections. Makes her debut in the 4th OVA.In Chapter 171, after some relatives marry, Uomi becomes Taka and Kotomi's family, making her a recurring character at the Tsuda home.

---

• Affectionate Nickname: Takatoshi refers to her as Womi-nee-san at her request.
• Ambiguously Bi: As time goes by, she becomes more akin to the idea of either sharing Takatoshi with Shino, or for the three of them to become an item. Later further implied in Chapter 490.
• Birds of a Feather: Due to their similarities, Uomi and Shino greatly admire each other and are close friends.
• Cool Big Sis: Played with. She tries to be this for Takatoshi and Kotomi as their senior (she's one year older than Takatoshi), but sometimes her kinky nature gets the better of her. Kotomi does like her to bits.
• Cuddlebug: She's known to have skinship issues i.e. she's prone to hugging people upon greeting them. Among others, she's hugged Shino, Suzu, Aria and Mori as well as Takatoshi himself. Needless to say, that last one tends to cause Takatoshi some problems.
• Didn't Think This Through: Becoming Taka and Kotomi's family involves the responsibility of sitting the latter whenever Taka has outings with the Student Council. It earns her brownie points, but the Student Council girls get to spend more time with Taka as a result.
• Drop-In Character:
  • Being from another school, the other characters sometimes wonder why she keeps showing up in Chapter 135. Later chapters reveal that she's become such a normal sight, no one bats an eye when she pops up anymore.
  • Following the marriage of their relatives, she's also a Drop-In Character at the Tsuda household. In fact, Takatoshi sometimes complains about her showing up unexpectedly. She even keeps a change of clothes in their house, and apparently has her own key.
• Expy: In-universe, of Shino, at least initially. Later appearances establish that she has quirks of her own and that she's more aggressive and flirty in trying to get close to Takatoshi.
• First-Name Basis: In Season 2, Episode 9 (Chapter 171), the relatives of Uomi and the Tsudas get married. She then starts calling Takatoshi "Taka-kun" and has him and Kotomi call her "Onee-chan," much to her obvious delight.
• Friendly Rivalry:
  • Even though they're rivals for Taka's affection, Uomi and Shino consider each other close friends and are not above a threesome, given the possibility... that is, if they manage to convince Taka. In chapter 435, it's shown that she starts feeling bad about gloating to Shino about staying at Taka's house because, while she does want to stay, she doesn't want to hurt Shino, or tread in that territory towards a person she considers one of her dearest friends.
  • Expanding on the previous point, Uomi also seizes the opportunity of the rivalry as an excuse to hang out with Shino and the other girls of the Ousai Student Council.
• Everyone Can See It: Hata reveals to Mutsumi that Uomi is rumoured to be romantically interested in Takatoshi (and considering how she acts towards him, no one can blame people for thinking so).
• Grass is Greener: As stated in Shino's entry, Uomi is envious of Shino for getting to spend her school week with Taka, which is considerably more frequent than Uomi's own visits to Taka's home.
• Hidden Buxom: Her breasts seem around Shino's size but are actually much, much larger — much to Shino's jealousy.
• Hidden Depths:
  • Regardless of her romantic intentions with Takatoshi (if any), it's shown that it's very important to her to be seen as a member of his and Kotomi's family, so she strives to be as doting as possible whenever she visits or stays in their home. She wants them to be her Family of Choice, as it's later stated in Chapter 246 that she's an only child, confirming that this is indeed her intention with them.
  • Albeit they're rivals, Uomi considers Shino as one of her best and dearest friends, as they're two peas in a pod. She likes Shino almost as much as she likes Taka.
• I Just Want to Be Loved: The main reason for her closeness towards Takatoshi, as she's implied to have had a lonely childhood.
• I Just Want to Have Friends: This is implied to be one of the reasons she goes to Ousai High so often, as she thoroughly enjoys spending time with the student council.
• In-Series Nickname: "Womi" by the Ousai Academi student council, because she's used to be called "president", but Shino already is referred to as such.
• Irony: She's the girl who became the closest to Takatoshi by doing the least amount of effort. However, she has spared no expense ever since in order to nurture that relationship, as she knows that Shino is a Worthy Opponent.
• Like Brother and Sister: Uomi is the girl who treats Taka the most affectionately out of all the girls that like him, as she became part of his family and likes to take care of him and Kotomi.
• Nice Girl:
  • Aside from her quirks, Uomi is a very affectionate girl and a doting friend to the Ousai Student Council.
  • One of the main reasons she doesn't outwardly pursue Taka beyond her occasional teasing is because of her respect for Shino.
• The Nicknamer: She has cutesy pet names for all the members of the Ousai Student Council.
• No Sense of Personal Space: She's developed a reputation of having these issues, as she's fine with hugging or rubbing her cheek against people when greeting them. Part of the reason there are rumours about her being interested in Takatoshi is because she's just as prone to doing the same to him as she is to the girls.
  • That said, when it's pointed out in Chapter 450 that she isn't as clingy with Takatoshi as she is with other people, she admits part of the reason is because despite naturally being clingy with him at first, she's recently become far more self-conscious of doing so. Shino and Suzu quickly suspect she's on the verge of a Love Epiphany and freak out.
• Nothing Is the Same Anymore: Becoming Taka and Kotomi's family changed everything for her. Aside from the kinky stuff (which is a constant with her from before the fact), being with them changed her from a Deadpan Snarker to someone that has so much joy in her life that she can't help to smile all the time. This implies that the feeling reaches beyond her liking Takatoshi, and in spite of her tendency to joke about it, it shows that Siblings Wanted was indeed something she coveted all her life. Girl now has a party in her heart.
• Off on a Technicality: Invoked and subverted. She is not bound by Ousai's ban on students having romantic relationships, so she technically has no impediments to pursuing Taka. However, Taka himself is bound to those, and Shino, Suzu and Aria will be more than ready to intercede and bring out the rules if Uomi does get serious.
• Only One Name: We're not told whether Uomi is her first or last name. She claims in an extra chapter that her first name is Christina, but whether she was being serious is questionable. Finally Subverted in chapter #415 where is suddenly revealed in a listing of the Student Council members that her given name is Chihiro and Uomi is her family name.
• Parental Substitute: Played for Laughs. She's touted as this in the Tsuda household, though she bounces back and forth between this and being Taka's "wife". In one occasion, she even had to fill in for Taka's parents in a parent-teacher meeting at school.
• Perpetual Smiler: Played with. Ever since she became part of Taka and Koyomi's family, she sports a gentle and kind smile.
• Pretty Freeloaders: Later in the yonkoma she eventually uses her "we're relatives now" excuse to not only drop by Takatoshi's house frequently but also stay over. To the point that she even keeps some clothes in his home.
• Running Gag:
  • She has an obsession with hugging Suzu just so she can feel if she's wearing a bra or not, much to the latter's annoyance.
  • She has a knack for showing up to Takatoshi's home uninvited. Though she is chided for this at first, she's basically family to Taka and Kotomi.
• Siblings Wanted: She adores the fact that she became Takatoshi and Kotomi's family, as she's an only child.
• Situational Sociability: Ever since she became part of Takatoshi and Kotomi's family, she becomes more effusive and smiles more frequently, especially in the manga.
• Ship Tease: She's the girl who pursues Takatoshi most actively, as she has a familial advantage to her rivals.
• Shipper on Deck: Played with. Initially seems this way for Takatoshi/Shino, but she later expresses interest in and goes after him herself. It later takes the shape of a Threesome Subtext.
• Shrinking Violet: According to her, she started as this, and still has the looks for this trope.
• Student Council President: Of Eiryou High School.
• Team Mom: For Taka and Kotomi at their home, as she takes care of them and cooks for them occasionally.
• The Tease: Probably the most active one out of all the female characters. Unlike the others who largely sidestep the issue or just bury their feelings, such as Shino, Uomi makes it more obvious she's interested in Takatoshi. Unfortunately, due to the influence/saturation of being around the other perverted girls, her hints tend to fly over his head.
• Threesome Subtext: A chapter has her casually referring to Shino as her "stick sister" in Takatoshi's presence. It's Japanese slang referring to two women who share the same man.
• Unknown Relative: In Chapter 171, she becomes part of Taka and Kotomi's family after they unwittingly go to a wedding where they don't know that the bride and groom are respectively related to them. Ever since, she's made a point of becoming close to them.

Nozomi Mori

Voiced by: Sumire Uesaka

Eiryou High School's Student Council Vice-President and a second-year student, making her Takatoshi's counterpart. Makes her debut in the 11th book as well as the 13th Seitokai Yakuindomo Bleep OVA.

---

• Birds of a Feather: A big part of the reason she and Takatoshi get along so well.
• Ensemble Dark Horse: In-universe example, as the girls interested in Takatoshi are horrified to see how easily the two of them get along.
• Hidden Buxom: Not even close. Unlike Uomi, who's ample chest is hidden under her uniform, Mori is noticeably well endowed.
• Innocent Innuendo: She and Takatoshi are prone to doing this when they're together.
  • In Chapter 304, she responds to Hata's question on her impression of Takatoshi with, "I feel at ease with him," which Takatoshi reciprocates (to the surprise of everyone present). Later still in Chapter 320, the two respond to Kotomi's question about what they were discussing with, "It's a secret between us two." For the record, Mori was asking Takatoshi to keep quiet about her changing in his living room (due to thinking it was Uomi's house).
  • In Chapter 372, Uomi has injured her hand, so she asks Mori to make lunch for Takatoshi and Kotomi. Unfortunately, Mori chooses to deliver the bento to Takatoshi while he's greeting students at the gate, making it look like she came all the way to Ousai to give Takatoshi a hand-made lunch.
  • In the same chapter, Takatoshi thanks her for the lunch and assures her it was delicious. Mori brushes off the compliment, but Aria and Shino reveal she's clearly blushing.
• Not So Above It All: Despite being otherwise very reliable and attentive to her duties, Mori is also prone to doing things one would expect of a typical high school girl such as wearing her swimsuit under her uniform (so she doesn't have to change). This is yet another way she and Takatoshi are similar, as Takatoshi likewise takes his duties as Vice-President seriously, but also acts like a typical teenage boy.
• Only One Name: Like Uomi, she only went by Mori (in Japanese Mori-san). Finally Subverted in chapter #415 where is revealed that her given name is Nozomi, making her full name Nozomi Mori.

• Ship Tease: She receives quite a bit of it despite only making a few appearances so far. This is deliberate, as the author gleefully invited readers to "look forward to their future friendship".
• Three Plus Two: Forms a trio with Uomi and Aoba of the Eiryou Student Council, until the new addition of Yuu Hirose makes them a quartet and truly the counterparts to the Ousai Student Council.
• Voice Changeling: Can do an impressive impersonation of Uomi’s voice. It was so spot-on that she once substituted Uomi for the Eiryou High Student Council broadcast when the latter had a cold.

Others

Toori Aoba

Voiced by:

The third member of Eiryou High School's Student Council. She made her first appearance alongside Uomi in the 4th OVA.

---

• Satellite Character: She only appears alongside Uomi and Mori, and has very little contact with the Ousai Student Council.
• Silent Snarker: When Mori finally snaps at Shino's shenanigans, Aoba mentally notes she expected Mori to do so sooner or later.
• Three Plus Two: Formed a trio with Uomi and Mori, though with the addition of Yuu Hirose it's now a quartet.

Yuu Hirose

Voiced by: Miho Okasaki

The newest member of Eiryou High School's Student Council, Yuu was recruited by Uomi due to her imposing height.

---

• Distaff Counterpart: To Takatoshi. In terms of height and strength, she's basically a female version of Takatoshi. Uomi recruited her specifically because she thought that a tall and strong member would be useful (after seeing how Takatoshi often helped out physically around the Ousai Council).
• Huge Schoolgirl: She's taller than Takatoshi, who himself is towering.
• Lady Looks Like a Dude: Like Toki before her, most people who meet Yuu assume she's male. It doesn't help that she cuts her hair quite short, and that the name Yuu is gender neutral (unlike Chihiro and Nozomi, which are clearly girls' names).
• Tomboy and Girly Girl: Compared to the rest of the Eiryou Council, Yuu is pretty blunt in her speaking style. This leads Mori to plead with her to try to speak a bit more appropriately for a girl.

Other Characters

Sayaka Dejima

Voiced by: Mutsumi Tamura

Aria's multitalented personal maid, who has some rather weird fetishes. Albeit she has kinks up to her scalp, she lusts over Aria in particular.

---

• Abhorrent Admirer: She's one for Aria. She does outrageous stuff in Aria's periphery, like stealing her underwear, sniffing and licking her clothes during laundry, watching her sleep, etc. It's heavily implied that she's two steps shy from outright assaulting Aria, though she never quite does.
• The Ace: There is seemingly nothing she can't do.
• Better the Devil You Know: In spite of being hugely, massively perverted, she's a valued member of the Shichijou household staff because she's tremendously reliable and a master at multitasking.
• The Comically Serious: She says incredibly outrageous stuff without blinking.
• Depraved Bisexual: If it has anything to do with sex, chances are she's into it or has already done it.
  • During one chapter where the Student Council was helping the Newspaper Club investigate reports of a kappa in a nearby river, said kappa turns out to be Dejima in a costume. For some reason.
• Fetish: For anything Aria has touched or worn, from her clothes to her chastity belt to her underwear.
• Hypercompetent Sidekick: To the Shichijo family. Dejima seems to have skills and knowledge in just about any situation that comes up. For example, she's certified to advise people on what plants are safe to eat in the mountains, is a trained lifeguard and is able to drive a modified limousine (that has been reinforced with ceramic plates and bulletproof glass) fairly easily.
• Jack of All Trades: She's competent at everything she does, and holds multiple professional licenses and certifications, enough to serve as an instructor for the given trade at the time.
• Lovable Sex Maniac: Even Aria, who is one of more perverted school-age characters, and interacts with Dejima most, is occasionally at loss for her blatant behavior. When in chapter 390 Aria invites her to drink tea together sometime, Dejima puts extra straw in Aria's glass, and helps herself. Aria responds with expressionless silence.
• Meido: For Aria.
• The Oldest Profession: She is implied to be/have been a literal prostitute — specifically High-Class Call Girl/professional Dominatrix — before becoming a maid for the Shichijou family. Notably, Aria's Arranged Marriage is called off because her prospective fiancé was one of Dejima's "valuable clients".
• Porn Names: In Chapter 638, she writes her "actress" name as "Dejima Sally".
• Shipper on Deck: In Chapter 469, when she encounters Kaede and Takatoshi in one of the Shichijo Family amusement parks, she teases Kaede that the two of them seem to be having a good time.
• The Stoic: Played with. She's generally The Comically Serious while on duty, but she can be just as large a ham as the rest of the cast.
• Supreme Chef

Others

Triple Booking

Voiced by: Yoko Hikasa (Shihoshi Idashi), Satomi Sato (Karuna Kisaragi) and Sayuri Yahagi (Yuuri Arina)

A popular idol group. Characters from the author's previous work Idol no Akahon.

---

• Expy: Shihoshi for Shino, Karuna for Aria and Yuuri for Suzu. Shihoshi is prone to mispronouncing words or making Freudian slips (unlike Shino's deliberate wordplay), Karuna is what Aria would be like if she was more serious (or at least less obsessed with sex), and Yuuri is what Suzu would be like if her age-matched her appearance.
• The Internet Is for Porn: Shishoshi casually mentions that Triple Booking is fully aware that their pictures are photoshopped onto porn pics, but just shrug it off.

Suzu's Mother

Voiced by: Miyu Matsuki

Suzu's doting mother, who is unfortunately just as sex-obsessed as most of the other characters (much to Suzu's embarrassment and horror).

---

• Amazingly Embarrassing Parents: When she heard the door open and close, she assumed it was her husband and offered a meal, a bath, or her. She then laughed and admitted the first two choices would wind up as the third anyway (a meal = naked sushi, a bath = bubble play). A pity it was Suzu, Shino and Aria who'd walked in...
  • In one of the OVAs, Suzu unexpectedly meets her in a park while walking their dog Boa. Suzu is surprised to see her, since she just saw her at home, to which her mother replies she and her father just had outdoor sex. Suzu considers moving out.
• Shipper on Deck: When she walks in on Suzu leaning over Takatoshi (she'd fallen off a chair she was standing on), she can't help but squeal in delight.

Hashitaka-san

The Shichijou family's Butler. Literally the voice of reason in their household.

---

• Almighty Janitor: Due to the fact that he and Sayaka appear to be the sole employees in the Shichijou household, he's often dragged out to fill whatever role either Sayaka or Aria tell him to do.
• The Drag-Along: If there's anything Sayaka may not do, it's him who ends up doing it because there's no one else available.
• "No. Just… No" Reaction: Most of the gags involving him are related to Sayaka's desire to assault Aria, as he both decries her perversions and stops her promptly.
• Only Sane Man: At the Shichijou estate. Between Aria, Sayaka and Aria's parents, there's not a single voice of reason in the whole house other than him.

Boa

Suzu's pet dog, who is larger than her. Presumably a white Labrador or a Golden Retriever.

---

• Angry Guard Dog: Played for laughs and largely downplayed. During a dog competition, Boa growls at Takatoshi because he's under the impression that he'll take his prize food (or perhaps Suzu) away from him.
• Big Friendly Dog:
  • Played for laughs. He's labrador-sized, but compared to Suzu, he's pretty big.
  • Boa is so well trained that at one point, he wins a dog competition with Suzu.
• Cuteness Proximity: Suzu's friends love Boa.
• Dog Walks You: Boa has a tendency to drag Suzu as he pleases. A couple of times, Boa is up to the task of carrying an asleep Suzu on his back.
• Living Macguffin: Played with. Suzu sometimes uses Boa as an excuse to hang out together with Takatoshi, to have a dog walk.
• Team Pet: Downplayed. Albeit Suzu's friends like Boa, his presence is not that prevalent to be considered part of the trope.
