   Keys: Hachimitsu Academy, Academy, Hachimitsu Private Academy

   Hachimitsu Academy is a private girls academy & fictional well-known strict girls high school that functions as the main setting of Prison School. The boarding school is located in Nerima Ward within Tokyo's metropolitan area, under the management of the Chairman with a student cohort of 1021 students. The school was constructed in 1961 as a high-ranking sports academy and boarding school for elite young women. The academy upholds traditional school rules on its campus.

   The school consists of a main school building & dorms surrounded by other buildings in the school grounds. The main building has many rooms; including (but not limited to) a library, classrooms, computer rooms, multiple single-gender bathing areas and a large canteen. The main building is also very large, capable of occupying the 1021 students in the student body at the start of the academic year comfortably. In the centre of the main building's courtyard is the school's Prison Block, where students undergo penal sentences for breaking the traditional rules of the School Code. The academy's main building is surrounded by very extensive school grounds, with green expanses, a forest, a waste disposal area, a cleaning room within the girl's dorms (run by the school cleaner) and a sports area. There is a wire fence separating the school from the neighbouring suburb.

   The school is presided over by the newly-appointed Chairman who heads the faculty & staff and is in charge of the school as of the start of that year. The official Aboveground Student Council only controls the weekly extracurricular agenda and the student clubs of the school. In contrast to this, the Underground Student Council has serves to run the school's Prison Block and has supplanted many senior roles in the school in its history, such as the yearly extracurricular agenda, school trips and student representation. Thus, the USC has an overwhelming influence across the faculty and student body far exceeding that of the ASC at the start of the year. For this reason, they attract more funding and have the prestigious honour of an office in the main building.

   The students attending Hachimitsu Academy are all required to wear the school uniform according to the School Code. However, many students regularly do not wear the full uniform or add their own variations without punishment. As the school is a boarding school, students hand in their laundry to a laundry room annexed to the girls' dorm where prisoner uniforms and other clothing is also cleaned.

   Hachimitsu Academy boys' uniform. The Hachimitsu Academy boys' uniforms consist of a blue blazer over a white, long-sleeved plain button-down shirt, a black tie on the collar, matching black trousers, and black dress shoes. The boys are often shown removing the blazer for hard labour. Some boys wear the uniform without a tie however. The male sports uniform consists of a white shirt and dark tracksuits.

   Hachimitsu Academy girls' uniform. The Hachimitsu Academy girls' uniforms consist of a camel blazer over a white, long-sleeved plain button-down shirt, a red lace cravat on the collar, a red plaid school skirt, and black dress loafers. Some girls wear a cream jumper over the shirt in the place of the school blazer. A few girls wear the uniform without a cravat however. The female sports uniform comprises a white shirt and dark shorts.

   Prisoners serving detention in the school's Prison Block wear prison uniform as part of their sentence according to the School Code. Male prisoners wear and striped black-and-white shirt with matching trousers over their underclothes with black dress shoes. Female prisoners wear a monochrome striped tank top and striped capri pants. The prison sports uniform consists of a striped tank top and striped underwear. Their uniforms are collected for cleaning by a guard member.

   The school has many student clubs in its social system, presided over by an official Aboveground Student Council run by President Kate Takenomiya and Vice President Risa Bettou with secretary Mitsuko Yokoyama. There is also an Underground Student Council, run by President Mari Kurihara and Vice President Meiko Shiraki, with secretary Hana Midorikawa and some junior members. At the start of the manga they begin to resist the addition of the boys into the school's cohort by secluding them, then resorting to harsher means, imprisoning them and secretly heaping physical abuse on them. This goes well with many in the student body who distrust the boys after their intrusion into a female-only bathing area.

2. #2Prison Block

   Keys: Prison Block, Prison

   The Prison Block commonly referred to as the prison is a penal compound located in the main courtyard of Hachimitsu Academy and the eponymous central setting of Prison School. The prison compound is historically controlled by the Underground Student Council who police the traditional aspects of the academy's school code, and are thus responsible for the one-month detention of the five first-year boys. The academic control of the building is ceded to the Aboveground Student Council after the USC's downfall, who orchestrate their two-month imprisonment in the facility. The warden of the compound is USC Vice-President Meiko Shiraki, until she is replaced by her ASC counterpart Risa Bettou.

   The Prison Block is a large and ominous prison compound in the main courtyard, cloaked by trees and shrubbery with a large iron gate in the archway. The building is surrounded by a large wire fence, separating the prison courtyard from the school courtyard in the centre of the main building. The building is most visible at night when the lighting of the school courtyard and the compound interior illuminates the walls of the Prison Block. The prisoners are seen wearing striped monochrome prison uniforms which are collected for cleaning by a guard member on a weekly basis.

   The Prison Block is a sprawling prison complex served by its own warden's office, a mess hall, a prisoner dormitory and bathing area. The building lacks any medical or cooking facility despite its size, with emergency cases referred to the nurse's office and all food delivered to the compound's mess hall by trolley. The building is highly secure with thick walls, a vast iron-gated entrance, iron gratings within the mess hall and prisoner dormitories, locked doors throughout the compound and a padlocked back entrance guarded by the warden of the compound. There is a solitary confinement cell near the warden's office, which eliminates any environmental light or sound from outside.

   Personality Bitch appears to have a lack of mental inhibition, making her immune to the sight of Kiyoshi Fujino's nudity and capable of showering him with lewd insults with the other gyaru schoolgirls. She behaves in a very degenerate manner, offering to show Kiyoshi her chest to achieve her goal of eliminating Kiyoshi and the USC cavalry team. This behavior results in her extending the same offer to Anzu Yokoyama, suggesting that she derives enjoyment from her immodesty. However, her emotional outbreak at seeing Kiyoshi wearing striped panties demonstrates some limit to her indecency.

   Appearance The chairman is a tall and handsome middle aged man with grey hair and black eyes along with a thin and neat mustache. He typically wears a white vest underneath a dark blue suit with light blue tie.

   During his stay in the hospital, he wears a typical male hospital uniform. After his escape from the hospital, he is seen only in an underwear. At one point, he wears Honey's torn thong. He eventually wears suit again after being reconciled with Mr. Important.

   Personality The Chairman is a grandiose and stern character who places emphasis on every ending word of his thoughts. He is a wealthy and influential man. He is a reasonable character who tries to judge the students fairly and unharshly, helping the boys; however, his sense of justice allows him to be manipulated by others. He is a compassionate person, as shown by his closeness to his daughter Mari in her childhood, his intervention on behalf of the boys and by filling a hole in the school wall with cement.

   Even so, he is an established pervert and is regularly shown watching porn or studying his original photo collection of South American women. He enjoys visiting South America and its beaches (the source of his collection), and has a fetish for women's asses over their breasts (pygophilia).

   In keeping with his authority and powerful aura in the school, his name has not actually been stated in the manga as his second name is implied from his daughters.

   Relationships Mari Kurihara Director and his daughter His eldest daughter. The two have a strained relationship since Mari dislikes her father’s obsession with female posteriors and would often catch him doing something perverted while at school. Nonetheless, the Chairman cares deeply for his daughter and was willing to bury his stash of ass pictures in order to become a better father figure. As a child, Mari was quite close with her father and would often hang out with him. Mari had even shared her father’s adoration for tight buttocks although innocently so since she was at the age in which she believed everything her father said. It is implied that her misandric views arose because of her father. Despite becoming distant with her father, Mari still cares for him such as when she bursted into tears when she thought her father had died in the helicopter crash during the cavalry arc. She was relieved after learning that he parachuted out safely, but immediately grew disgusted after witnessing him, clothes in tatters, wearing a woman’s thong.

   Chiyo Kurihara His youngest daughter. Although they rarely interact during the story, it is implied that he is on better terms with her than he is with Mari.

   Kiyoshi Fujino The Chairman was impressed by Kiyoshi’s answer to the ass vs tits question and recognizes him as a true assman. Otherwise, they have very few interactions during the story. It is unknown to what extent is he aware of Kiyoshi’s affections for his daughter, Chiyo.

   Honey Brief lover (she affectionately calls him “Darling”). They first met when she hitchhiked a ride in his car after witnessing her ass. During their first exchange of dialogue, she was able to quickly adapt to his delayed speaking pattern. When they meet again after he had lost his memories, she lies to him by saying that he is her fiancé when in fact she was engaged to Mr. Important. While fleeing from Mr. Important’s henchmen, they also engage in intercourse on a few occasions. Their brief fling supposedly ended after Honey reconciled with Mr. Important.

   Mr. Important They initially disliked each other due to their affections for Honey and various misunderstandings involving a bear hunt.

   Keys: Chiyo Kurihara, Chiyo

   Name: Chiyo Kurihara Gender: Female Hair Color: Brown Eye Color: Purple

   Relatives Chairman Kurihara (Father) Mari Kurihara (Older Sister)

   Chiyo Kurihara is a supporting character of Prison School. She is a first-year student in attendance at Hachimitsu Academy, a member of the school's Go Club, the daughter of Mr. Kurihara, the younger sister of Mari Kurihara and the love interest of Kiyoshi Fujino.

   Appearance Chiyo is a pale-skinned teenage girl with shoulder-length brown hair that has square bangs hanging over her eyebrows, big brown eyes, full pink lips and Kiyoshi Fujino describes her as the cutest girl in the class that her cute outward appearance belies her strength.

   She is usually seen wearing the standard female school uniform.

   During her incarceration, she wears an oversize female prison uniform consisting of a striped short tank top and carpi pants until Kiyoshi lends her his more form-fitting prison uniform.

   On her first date with Kiyoshi, she wears a pink hooded sweater with a half-length dress (one of the few times she is seen not wearing the school uniform).

   Personality Chiyo is a kind & sweet girl who is notably one of the only female students that is not opposed to the admission of boys in Hachimitsu Academy.

   She is an avid fan of sumo wrestling with the dedication to physically purchase tickets for a sumo student tournament. Her commitment to sumo wrestling is what inadvertently results in meeting Kiyoshi Fujino & befriending him. Chiyo's love of the sport is strong enough that she believes her grandmother's statement: "any fan of sumo wrestling cannot be evil".

   After Kiyoshi breaks out and goes to the tournament with her despite knowing nothing about sumo, Chiyo chooses to interpret Kiyoshi's actions positively because of his "never-say-die" attitude. This continues throughout the series as Kiyoshi's actions become successively more extreme and strange.

   Chiyo has a strong sense of justice, defending Kiyoshi and the boys when he is blackmailed for expulsion by the USC. In particular, Chiyo is a protective and loyal companion to her best friend Mayumi Tanaka and she is willing to put herself in harm's way for her. When girls try to bully her into getting blackmail photos on behalf of Kate Takenomiya, she shows the mental tenacity and physical strength to defend herself and protect Mayumi using sumo moves.

   Chiyo can be quite naive at times, and this is shown in particular when she does not know of the USC's existence when her sister Mari is the president. Chiyo is apparently completely oblivious to the fact that Mayumi and Kiyoshi do not share her interest in sumo wrestling. Chiyo even manages to mistake Hana Midorikawa's sudden disappearance into the mountains as a personal training camp & Kiyoshi being missing as sheer coincidence.

   Moreover, this also holds true when she mistakes all the actions for the USC's escape plan for a surprise birthday party. Such is Chiyo's consciousness and purity that she is incapable of thinking ill of another person, even after learning the true nature of the relationship between Hana and Kiyoshi.

   Appearance Hana is a slightly short and lithe young woman with blonde hair that is styled in a cute bob with square bangs covering her eyebrows (she used to wear her hair in pigtails when she was younger), brown eyes and she is athletic and somewhat muscular despite her light build as a third-grade Dan and the fourth-best karate champion in the inter-high school championships.

   She wears the standard school uniform with no socks in tandem with blue leggings and an undershirt.

   Personality The first impression of Hana by the boys was that of a kind and cheerful individual who enjoys brewing and drinking dandelion tea, and also has a love for four-leaf clovers. However, it was quickly shown that she can get very violent when angry and expresses her anger with proficient karate attacks. Just like her peers, Hana displays a lot of hostility towards boys.

   She is somewhat reserved in comparison to Meiko Shiraki (the Underground Student Council's Vice-President), wearing underlayers when on guard duty. She is actually very shy and impressionable as shown when she is caught in compromising conditions by Kiyoshi Fujino a number of times. Hana is shown to be quite innocent in contrast to her more tough exterior persona, as she faints or becomes mortified when she finds herself in compromising or sexual situations.

   Hana has a fear of mushrooms as a result of remembering the hospital visit. She has a mild obsession with Kiyoshi, which later develops into a crush after they kiss.

   Hana is very good at making tea, being praised on several occasions.

   Appearance Honey is a tall young woman with an athletic and buxom figure. Though she is described as the posessor of a beautiful face and body by the Chairman, her derrière is the singular target of fascination and adoration from him.

   Personality The manipulative nature of Honey is shown in her initial manipulation of the Chairman to complete construction labour for her.

   Keys: Jouji Nezu, Jouji

   Name: Jouji Nezu Gender: Male Hair Color: Black

   Jouji Nezu nicknamed HideJoe or Joe, is a supporting character of Prison School, and is one of the five first-year boys in attendance of all-girls school Hachimitsu Academy. His love interest is Satou, a member of the school's cooking club. Joe was originally a secondary protagonist sharing equal focus with the other boys, but he gradually became less prominent after his release from the prison.

   Appearance Jouji is the shortest of the five; due to his frail constitution, he is rather weak and gaunt. No matter what he wears, Joe is always seen wearing a hood over his head that casts his eyes and most of his features in heavy shadow. The hood itself is revealed to be completely detached from any clothing, thus enabling Joe to wear it with anything — even in the pool. During his imprisonment, he wears the standard male prison uniform of white striped overalls paired with his signature hood. When Gakuto triple switches with Joe and Chiyo, it is Jo who impersonates Gakuto by wrapping bandages around his forehead and wearing glasses. After release from prison, Jouji goes back to wearing the standard male uniform.

   Personality Joe is the sullen oddball of the five boys, who struggles to fit in outside his group of friends (and sometimes within). He suffers from a bloody cough due to severe stomatitis, though the disease is neither chronic nor physically debilitating to him. However, his canker sores do affect his speech, with bloody coughs often punctuating his sentences and interrupting his speech. Despite being the quietest, Joe is actually one of the more lecherous of the five, reflected in the crass way he speaks and makes jokes. Joe also has a love and appreciation for ants to add to his quirks, going so far as to name the ones he keeps in his ant farm and being able to tell them apart — though they all look alike. Towards his friends, Joe is shown to be accepting and supportive. Though he initially shuns Kiyoshi after he learns of his escape, Jo returns the kindness shown to him after Kiyoshi prevents him from assaulting the USC president. Due to being the last of them to have spoken to a girl out of the five boys, Jo enters a depressive phase after being freed from prison. As a result, he decides to attempt returning to the Prison Block out of loneliness as the other boys are enjoying their freedom. However, his outlook on life in the school improves when he meets Satou.

   Relationships Shingo Wakamoto Out of all the boys, Joe is closest with Shingo likely due to their blunt personalities. They are often seen hanging out together. They also briefly developed a rivalry when they were trying to determine which girl (their respective love interests) would become their cavalry rider.

   Takehito Morokuzu Gakuto is Joe's close friend from middle school. Early on in the series, Joe would often use every opportunity he could get to joke about Gakuto’s pants-shitting incident or his "gay relationship" with Kiyoshi. Their relationship took a strange turn when Gakuto enlists Joe to help him understand Mitsuko’s yaoi obsession by performing yaoi acts on one another. Joe strangely becomes engrossed with the yaoi practices to the point that he would try to convince Gakuto to continue their arrangement and become fixated on Mitsuko’s doujin involving him and Gakuto. However, Joe later abandons the doujin and supports Gakuto's plan to free the Underground Student Council.

   Satou Joe’s classmate and love interest. He often appreciates it whenever she gives him a cupcake or mochi snacks. Aside from his friends, she is one of the few people he admitted his ant obsession to. He avoids calling her by her real name and often addresses her with nicknames like Cake-san, Diamond-san, and Star-san. During the cavalry battle, he was shocked to learn that Satou had a university boyfriend (who they later find out is cheating on her).

   Mitsuko Yokoyama When Mitsuko was about to incinerate her doujin of Joe and Gakuto, Joe stopped her and encouraged her to complete her doujin. He acts as her editor and claims himself to be her number one fan. Gakuto misunderstood their relationship when he spotted them working together. However, Joe eventually stopped helping Mitsuko make the doujin and instead backed up the Underground Student Council.[1].

    Keys: Kate Takenomiya, Kate

    Name: Kate Takenomiya Gender: Female Hair Color: Orange Eye Color: Green Height: 161 cm (5'3").

    Kate Takenomiya is an antagonist of Prison School. She is a third-year student in attendance at Hachimitsu Academy and the president of the official Aboveground Student Council of the school.

    Appearance Kate is a slightly short and slim girl with chest-length scarlet-orange hair that is tied in two low pigtails by burgundy ribbons where it is styled in drill curls with bangs swept to the left side, green eyes that has long curlicue-like eyelashes, thin eyebrows and a normal bust.

    Kate wears the standard female school uniform without stockings or socks.

    Personality While Kate shows her cruel and sadistic self in doing so, she is a ruthlessly manipulative and shrewd girl who acts to make gains at the expense of others. A sinister character who displays intelligence and cunning throughout the series, Kate has proven a dangerous enemy to anyone who crosses her.

    In middle school, Kate was well known for her intelligence, combative ability (as a capable Aikido user), leadership abilities and talent - until she was surpassed by a newly enrolled Mari Kurihara. Though Kate was responsible for bullying a younger Meiko Shiraki in middle school for her large breasts, Meiko became more confident and was prevented from beating Kate up by her to-be arch-rival Mari. This indicates her bitterness towards Mari is due to her strong feelings of jealousy since childhood.

    The middle-school incident is the cause of a serious inferiority complex driving Kate's actions, stemming from Mari's higher capability in every possible area in comparison. She is greatly motivated by her hate of Mari and a powerful urge of vengeance for the embarrassment that incident caused her. This hate eventually turns into a deep obsession with Mari that's sexual in nature. She is unable to resist Mari forcing herself onto her, and submits to various sexual acts with her (such as sucking Mari's breasts).

    Ultimately, Kate has been shown to put indomitable effort into any task she sets upon herself which Mari praises by saying that she is a strong-willed person & hard-working. The kindness Kate shows to those who she considers friends is strong, as shown with her close relationship with her loyal aide and best friend from middle school Risa Bettou. Kate has also shown a few perversions, willingly engaging in foreplay with Mari when the latter films her for revenge, wearing Mari's stolen underwear from middle school and showing visible excitement while she is filming Mari and Kiyoshi Fujino in the bathing area of the Prison Block.

    Relationships Mari Kurihara She is one of the people she has the most resentment for, because she treated her as an ignorant person in front of her classmates in elementary school, she always wanted to be equal to Mari reaching the point of obsession as seen in Chapter 162 from the manga. Driven by envy, she always seeks to harm her by affecting her loved ones. She psychologically destabilizes her friends Meiko and Hana in order to achieve the dissolution of the Secret Student Council and subsequent final separation from the friends. In addition to embezzling Mari's actions before the school, thus degrading her reputation until it reaches the ears of her sister Chiyo Kurihara. Despite being envious of Mari, her obsession reaches the point of wanting to become her.

    Meiko Shiraki Kate's inferiority complex causes her to act cruelly towards people of weak character to affect her self-esteem and reduce them to little, as it happened with Meiko, when they were girls before they both met Mari, she pretended to be her friend while humiliating her in middle school for the size of her bust, forcing Meiko to sing a song that she made up (where she made fun of the name Meiko and her physical appearance). After Mari's arrival at the academy and she became friends with Meiko, Kate became more interested in Mari than in her and teased her through third parties so that she was not a friend of Mari. Growing up and since I present the change of the young Meiko to what is now "the Vice President" you can notice the strong discord between the two,

    Risa Bettou He considers her a friend, also someone to count on to carry out his evil deeds and impart order, yet he does not have the confidence to reveal her secrets by not allowing Risa to enter his room when Mari's supposed escape from the room was discovered. prison. Since he met her two years ago, Kate has rarely shown her kind and complicity side, one of those times being when they met at a fast food restaurant where Risa was upset by receiving a wrong order and Kate defended her against the misunderstanding of the moment. Since then they have maintained this relationship of friends, becoming implicitly close.

    Mitsuko Yokoyama She is one of her subordinates in the Student Council, the relationship between the two is not very close, each one fulfills her work within the council without any kind of enmity. They develop as colleagues within the work environment without actually considering themselves friends.

    With martial arts skills from Kate's childhood years, she is a capable Aikido practitioner.

    During his stay in the Prison Block, Kiyoshi wears the standard male prison uniform of a sleeved white striped shirt and striped trousers. In his second stay, he wears boxers for some time because of giving his shirt and trousers to Chiyo Kurihara.

    Personality Kiyoshi is a level-headed individual who seems to have a strong resolve under hard pressure. Unlike the other boys, he does not let his desires get ahead of him, and tends to be the rational member of the group. Kiyoshi is markedly the most normal of the boys in design and character, as well as the main narrator of the manga in thought.

    He is tenacious but lacks the stubborn perversion of the other boys. However, he is capable of sometimes doing things that seem untoward or shocking to the other boys, such as cross-dressing to escape the Prison Block. Though he has sexual desires, he is much better at controlling them than the others; this is shown when he refuses to take advantage of Chiyo Kurihara's attempting to throw herself at him due to her feelings of insecurity and inferiority towards her sister. Kiyoshi develops a deep love for Chiyo and this love is the drive of most of his actions throughout the series, and he engineers breakouts, sacrifices his first kiss, and goes to extreme lengths to stay in the same school with her and develop their relationship. Kiyoshi can be oblivious to his selfishness sometimes as seen when he intended to use the money that he gathered from other to buy something for his own personal reason. Kiyoshi can also be insecure with the other students and can be driven to action by other people's resolve, like when he sticks to the Prison Block breakout so Gakuto could get his collectible figurine.

She befriended a younger Mari and she regains her confidence when Mari convinced Meiko to defend herself from the bullying. However, when she was led into believing that she burned a tree and killed Mari's crow hatchlings as a result, she loses confidence and reverts to her prior shyness.

    Relationships Mari Kurihara Mari and Meiko have been friends since middle school, in addition to being the first one she had. She has great admiration for her to the point of being obsessed because every time Meiko makes a serious mistake or a carelessness, she starts to sweat too much.

    Noted to have been the leanest of the five, Gakuto gains muscle in the Prison Block from hard labor to become lean and tall with an average weight.

He is thus the mastermind behind a lot of the organized breakouts in the prison along with Kiyoshi Fujino. Gakuto's plots also prevent the boys from being excluded several times. He is obsessed with the Three Kingdoms and is the smartest of the five.

    However, in rare cases, if Takehito realizes that the plans he organized are failing and there is nothing he can do or think of, he would begin to get stress to the point of losing his own sanity out of frustration and gets driven into a state of crazed, ignorant and foolish actions; this was showcased two times in the manga.

Gakuto has an eclectic & archaic style of speech, punctuating his words with "indeed".

    Gakuto most likely has some knowledge of the French language. The kanji for "Takehito" can be also read as "Gakuto".

    The favourite character of Gakuto from the Three Kingdoms is Zhuge Kongming.
