Fetish: Pregnancy
Weak spot: Her inverted nipples

The protagonist's cousin and also Mei's daughter. She is the respective class president of her class and also seen as the school's role model. Because Mei believes that her daughter inherited her "genius genes" and an expensive high-class sperm bank donor's genes, Arisu should be as great as she is, and projects her beliefs on her. Mei doesn't hesitate to beat and humiliate Arisu if she fails to achieve her expectations and, if she's mad enough, she may do it even in front of other people.

When they where young, the protagonist confessed to her and she answered that "It would be embarrassing if it became a rumor", but the protagonist didn't get mad about it and instead thought of it as a good juvenile memory. But in reality, Arisu wanted Hassaku to really go after her. However, Hassaku gave up after the first try, as he didn't want Arisu to hate him for being insistent. And when Arisu finally decided to check why he wasn't going after her, she saw his sisters flirting with him, giving her no openings. Refusing to lose to Mao, who her mother insisted she could't lose to, she became stubborn and tried to get Hassaku's attention by treating others as she was better than they were.

Contrary to her stubborn and snobby personality, her nipples are shy and inverted, but once taken out she will surely become honest and say "Abuse me until I'm pregnant!", solving her complicated first love.

Fetish: Voyeurism and recording
Weak spot: Watching herself having sex in a mirror/filming

The protagonist's aunt and the little sister of his late mother. She is also Arisu's mother. After the protagonist's parents died, she became the new principal. She wants to help establish the "Mechacon System", which is a system where rich men have many wives in order to have many children.

To accomplish her goals, she is making the school a place where male students can't tolerate abuse in order to become a ladies-only school, a place to basically raise and sell rich wives to rich men, which goes against the protagonist's parents ideals of true love.

Mei believes she's very cute and has a very high self-esteem. She wants to always stay young and beautiful. She is also a pervert who puts cameras everywhere in the school and gets excited while watching the students.

She has an inferiority complex towards the protagonist's mother and tried to steal her husband by making him drunk. Despite managing to have sex with him, he chose the protagonist's mother, and later both of them died in an accident. With her goal lost, she tries to project her ideals and objectives on her daughter Arisu, whom she only sees as a tool, and is not afraid to beat her up for her mistakes.

Fetish: Phallic Servicing
Weak spot: Toes

Yuzuki's retainer. Her family has served the Ryuugasaki family for generations, and because of that, she is now serving Yuzuki, but Gumi isn't an "ojousama" herself and is only permitted on the school because of her position.

She loves phallic objects, large penises and long sex. When she saw the protagonist having sex she fell in love with his penis instantly, as if it were a matter of course. Her weak spot is her toes and be servicing or being serviced, if it's about her toes she'll like it. Also phallic objects excite her so much she loves giving service to them with her mouth, vagina or any other body part.

She often takes midnight walks in the corridors accompanying a naked masochist Yuzuki, which usually makes her get carried away and shame and bully the masochistic Yuzuki. She actually hates Yuzuki and when Yuzuki shamed the protagonist and insulted her loved dick, that was the last straw. She swore loyalty protagonist, or at least his penis, ant told him about Yuzuki's naked routine.

A gyaru in heat all year round. Because she used to say dirty words in almost all her phrases, would pick up guys at the streets and even seduced her step-father, her mother forced her to enter the prestigious school, but she has no interest in it or following the proper etiquette.

She gets really excited when she hears dirty words, and when excited she says and wants to hear even more. Whenever Maron opens her mouth, majority of her sentences consist of words like "dick" and "pussy", but there seems to be a reason she's like that...

A girl that seeks sex just because she's bored. Such girl deserves some punishment! The protagonist takes up the task to teach her the difference between sex with and without love. She likes it when her ass becomes red from spanking.

Fetish: Sadism (especially insulting), masochism
Weak spot: Being trained

A frivolous girl, the school's problem child who aims to become a detective. Sister Natsume's little sister, however because of their stark differences they don't look and feel like sisters at all. She's rumored to pick both fights and men on the city, and because of that, the ojousamas in her class are afraid of her and avoid her.

Kotori has the courage to point when someone is doing something wrong, and that makes the protagonist to start to admire her. She also hates the fact that she was born into a religious family, basically a family who follows blindly what the bible and other people say, especially her sister.

Kotori loves insulting and pointing out people's flaws. She gives a cold impression at first, but after she's warmed enough to you, you can see she has a surprisingly obedient side to orders and training. After falling in love, she will become completely submissive to you, but still a sadist to others. Confess and show your love for her during sex and she will just melt!

<hidden by spoiler settings> Recently she's thinking about what is love, and ended up thinking that she doesn't have love inside her. Show her she's wrong.

The protagonist's homeroom teacher and the school's sister. Kotori's older sister whose appearance gives out a strict and serious impression. She treats all of the students equally regardless of their sex; if they're a good student, she won't oppose their enrollment.

Natsume has always been serious since she was little and cannot understand why her sister is turning into a delinquent student, and it hurts her.

Being so serious for so long Natsume has trouble to expressing her feelings. She also wants to be spoiled and do whatever she wants, just like her sister.

Fetish: Exhibitionism
Weak spot: Sensory Deprivation

The current student council president. Mao's rival and Gumi's master, a person who is rumored to be able to do anything. She used to be unbeatable in every aspect, until Mao appeared and managed to outnumber her. Yuzuki felt as if she lost her footing suddenly, like the descend of a jet coaster, and that made her extremely excited. She is very obedient to her father.

She and Mao always fight with polite, sharp and venomous words every time they meet, but Mao's composure makes Yuzuki lose the argument every time. She wants to see Mao's face when Mao loses her composure, and to do so, she is tries to make the protagonist her slave. Despite all this, they join forces if it means to anger the principal as both Yuzuki's father, Yuzuki and Mao hate her.

She has an arrogant personality and when she's close to her period she becomes sadistic; the closer to she's to her period, the more sadistic she will become. However once she it starts, she reverts back to her exhibitionist, masochistic self and will engage in naked night-walks accompanied by her retainer Gumi.
