It was serialized in Kodansha's Weekly Young Magazine from February 2011 to December 2017. Yen Press licensed the manga for English release in North America.

Plot

Hachimitsu Academy, one of the strictest girls' academies in Tokyo, has decided to admit boys into their system. Kiyoshi Fujino is one of these new boys, but he discovers to his shock that he and his four friends—Takehito "Gakuto" Morokuzu, Shingo Wakamoto, Jouji "Joe" Nezu, and Reiji "Andre" Andou—are the only male students among 1,000 girls. The draconian laws that are still in place make the school even worse, which punishes even the most minor infractions with a stay in the school's prison. The five boys all commit voyeurism in the school's bathing area with the lecherous philosophy of "all for one, one for all". Their capture and "arrest" by the Underground Student Council causes the five boys to receive an ultimatum: either stay a month in the school's Prison Block or be expelled. The boys are incarcerated in the Prison Block together and Kiyoshi is overwhelmed by the discovery that all the other boys are masochists that revel in the punishments handed to them by their attractive but vicious supervisors.

Although not very bright, he often comes up with the most successful plans when he's at the end of his rope. Due to several embarrassing mishaps, he becomes a regular target of Hana while in prison. So far, he is the only one of the five boys to have been sent to prison more than once. When the ASC takes over and during his second imprisonment, he becomes an ally to Mari who is also a prisoner.

Portrayed by: Tokio Emoto

Nicknamed "Gakuto", he is the bespectacled boy in the group. He has an otaku interest in the Three Kingdoms, having enrolled from the same middle school as Joe.

Despite his perverted behavior, he is shown to be an excellent strategist who employs tactics referenced from famed generals of either The Three Kingdoms or other ancient battles - a skill that has proven very useful in most of their plans. His love interest is Mitsuko. Due to his strategic intellect and willingness to sacrifice everything for his friends, Gakuto has quickly become a popular character in the series.

Voiced by: Daisuke Namikawa (Japanese); Christopher Bevins (English)

Portrayed by: Daiki Miyagi

Voiced by: Sayaka Ohara (Japanese); Tia Ballard (English)

Portrayed by: Hirona Yamazaki

Mari is the president of the underground student council. She is the daughter of Hachimitsu Academy's chairman and the sister of Chiyo. A cold and calculating figure who seeks to uphold the school's traditions and rules. From the very beginning she immediately despises the boys, and the chairman's decision of integrating the academy. Much of this stems from her own resentment of her father's perverted behavior. In middle school, Mari helped Meiko stand up for herself when she was bullied by Kate, and the two have remained close friends ever since. She, like the rest of the Kurihara family, employs a strange philosophy to judge one's character. Her philosophy is, "Anyone who likes crows isn't all bad."

The strongest student in the school, and proficient in Judo, Meiko is a harsh disciplinarian over the boys, and often punishes them for the slightest infraction, with Gakuto being a popular target. Although a powerful and intimidating figure, she deeply fears displeasing Mari, which manifests itself in body-wide excessive sweating. Similarly, she enjoys performing calisthenics, and is often seen comically performing odd exercises with a large puddle of sweat underneath her. Aside from working out, she has been shown to have a knack for cooking. Because of her voluptuous/athletic physique, her school uniform barely manages to hide her body often leading to comical wardrobe malfunctions.

Hana Midorikawa (緑川 花, Midorikawa Hana)

Voiced by: Kana Hanazawa (Japanese); Alexis Tipton (English)

Portrayed by: Aoi Morikawa

Hana is the secretary of the underground student council. She mostly ends up in the worst situations with Kiyoshi, whom she eventually develops feelings for. She is also an adept martial artist, often utilizing her karate skills to brutally punish the boys if Meiko's harsh punishment doesn't work.

While Shingo has another outing at the arcade and meets Anzu again, at the prison, Meiko reveals she is in possession of Gakuto's figurines and gives Gakuto a choice to confess to aiding Kiyoshi's escape and have everyone's sentences extended again or to spare his figurines. Much to everyone's surprise he throws them on the ground and breaks them. As Gakuto personally confesses to the breakout to his friends, Shingo becomes shocked at everyone's forgiveness.

Meanwhile, Meiko gives Shingo more free time outside, warning that his failure to return at 6:30 PM would result in a breakout. The other boys are assigned a job reinforcing the prison gate, crossing paths with Chiyo, who glances at Kiyoshi with a hidden message. Later, Meiko's voice calls out "punishment time" to Andre, leading him to find his diary in the Corrections Office, which entices him to go outside. With Chiyo's message deciphered, Kiyoshi, Gakuto, and Joe head out to warn Andre, but he breaks through the fence and receives his punishment, only to be subdued by Hana for a prison break offense as Meiko is outside of the prison boundaries. It is also revealed that Shingo's date with Anzu was only a way to stall for time. Nevertheless, Shingo arrives before 6:30 with the help of the laundry man, but fails to open the gate which the boys worked on earlier. With three breakouts in tow, the five of them meet the Chairman to discuss their expulsion, which Chiyo attempts to intervene but fails to find physical evidence of DTO.

Shingo recalls that at the Corrections Office there was an email labeled DTO. However, Andre says that the USC may have planned ahead of time and deleted the email. Despite this, Gakuto notes that the email can still be recovered through a data restoration software. To take the cell keys to access the Corrections Office, the boys lure in Meiko by staging an arm wrestling match and berating Meiko into challenging them, in which she accepts. Gakuto manages to sneak into the Corrections Office, to which he needs at least ten minutes to download the software and search for the email. Despite Kiyoshi, Shingo, and Joe's matches barely lasting a minute each, Andre manages to almost hold out the rest of the remaining time, losing the match nine minutes in. Before Meiko almost discovers her keys went missing, Gakuto picks them off the ground and hands them to Meiko before she leaves. While the others praise Gakuto's timely return, he expresses his failure to retrieve the deleted email, only having downloaded the software. Facing imminent expulsion, Kiyoshi and the others reconcile with each other before heading off to sleep.

Kiyoshi and the others have lost hope, except for a crazy Gakuto who makes nonsensical breakout plans. Meiko gives the boys the request of choosing their last meal. Gakuto's fried grasshoppers and rice dish proves to be so disgusting that he breaks free of his irregular state, and inspires him with a legitimate breakout plan, after looking upon Kiyoshi's note from Chiyo. He discusses the plan with the others, but they say they are short on time to carry it out. After Meiko hands them their withdrawal papers, Kiyoshi suggests to write an appeal to the Chairman to have more time for Gakuto's plan. To her surprise, the Chairman responds back to the appeal; it is revealed that the appeal Meiko had ripped was a decoy, and that Kiyoshi used his knowledge of the Chairman's buried explicit photos to persuade him to come. He will postpone the expulsion date only if in a Boobs vs. Butts debate, Kiyoshi's preference aligns with the Chairman's. Meanwhile, as Meiko tries to eavesdrop outside the prison, Hana goes berserk, as the repressed memories of her and Kiyoshi under the hospital bed surface once again. Despite the Chairman declaring the expulsion postponed, the boys only have a one-day reprieve. As the USC decides on their next move, Hana personally agrees to watch over the boys on their final day.

Gakuto's plan to distract Meiko falls apart when Hana arrives instead. Mari thought the boys were used with Meiko's behavioral patterns, and agreed to have Hana overseeing the boys. Kiyoshi exploits Hana's grudge and takes it upon himself to sneak inside the Corrections Office. As Chiyo intercepts another Kiyoshi's message inside his lunch tray, she gets caught by Anzu, who wishes to help the boys out of expulsion. Later, Gakuto deliberately gets stabbed in the forehead with a fork by Joe to be bandaged by Hana in the Corrections Office. As Gakuto returns, Kiyoshi goes with Hana there, while Chiyo and Anzu are outside, and Meiko patrols the prison. Then, Hana gives a plastic tube to watch Kiyoshi pee in. Full of confidence, Kiyoshi strips down and manages to unlock the back door, but drops to the ground after getting kneed by Hana. She prepares to pee on him, until Meiko's apprehension alarms Hana, who locks the door again. Much to the boys' relief, Anzu was the one that was caught and not Chiyo, sacrificing herself so Chiyo can get inside. As Hana holds the door, she then kisses Kiyoshi, stating that stealing his first kiss away from Chiyo is her revenge against him.
12	"Good Morning, Prison!" Transliteration: "Guddo mōningu purizun!" (Japanese: グッドモーニング プリズン!)	Tsutomu Mizushima	September 25, 2015 (2015-09-25)
Chiyo waits at the back door of the Corrections Office, where Kiyoshi and Hana's confrontation is taking place. As Hana goes in for another kiss, Kiyoshi counterattacks by sticking his tongue inside Hana's mouth, completely shocking the sexually pure Hana and resulting in a profuse nosebleed. She leaves the Corrections Office, and Chiyo comes inside. As Kiyoshi returns to the prison, Hana allows Gakuto and Joe to use the bathroom, before the five head off to bed. Suspicious, Mari and Meiko proceed to patrol the prison, before declaring it inescapable. The next day, Meiko takes the boys to the Chairman's office. Meanwhile, Gakuto runs inside the school, causing the schoolgirls to beat him up. As Kiyoshi declares that they themselves have won, Meiko catches on to their ruse and grabs Joe disguised as Gakuto, and Chiyo disguised under Joe's hood. Gakuto is thrown into the Chairman's room by the students. Then the boys explain that Chiyo sneaked in from the back door of the Corrections Office, where she met with Gakuto and Joe inside the bathroom, performing a three-way exchange with each other's clothes. Under disguise, Gakuto made his way to the Corrections Office, enduring his cut from the fork to have Joe disguised with the use of bandages. Gakuto hid himself outside while Mari and Meiko were patrolling. When Meiko expresses disbelief at how fast the DTO email would have been recovered, Gakuto tells her of the data restoration software being downloaded ahead of time during the arm wrestling match. As Gakuto passes the DTO's information hard drive to the Chairman, Hana discovers Kiyoshi's manipulation and proceeds to punch him, only to punch Mari instead, who wholly confesses to the DTO plan. In a post-credits scene, while the boys seem content outside of their prison lives, the prison-clad USC make their way to the school prison. They are charged by the Aboveground Student Council (ASC). News about their abusive incidents have been spread around the school.

As news of the USC's prison stay circulate around the school, Mari and the others are led to their cells. With the ASC enforcing their role as guards, President Kate Takenomiya orders them to put on their prison uniforms, and while Mari reluctantly gives in, Hana and Meiko's defiance results in a brief scuffle with ASC Vice-President Risa Betto. As the boys are having lunch, they are interrupted by Chiyo and Anzu, where Chiyo reveals that in the USC's prison sentence, extreme abuse methods were reported to cover up Operation DTO. Angered by Kiyoshi, Shingo, and Andre's romanticizing, Gakuto storms into the library and becomes acquainted with Mitsuko Yokoyama, the ASC Secretary over a Three Kingdoms book. Meanwhile, Joe questions life outside the prison after scaring away a trio of girls over his ants. During the night, while Gakuto confides to the others about Mitsuko and their clumsy experience, Joe laments to Andre about his failure to find a girl and how life with the five of them in prison seemed better. As Gakuto and Mitsuko have another outing, Andre narrowly stops Joe after he attempts to grab a girl's butt to return to prison. The next day, Mitsuko witnesses a naked man in bondage rope and after getting wrapped up in the same way, becomes identifiable by Gakuto and Andre. When Andre realizes his rope went missing, Andre runs to the pool locker room to stop Joe from exposing himself. As Mitsuko trips and rides away on a cart of wax drums, she crashes into Andre on the way, spilling the wax as both slide down the school halls. Making haste to Joe's location, Andre peels back his clothing while Joe is offered a cupcake by Sato, Joe's first girl interaction. As he witnesses Joe talking to Sato, he rams into the locker room naked in bondage rope. As Kiyoshi and the others rush to the scene and single him out as the rumored bondage man, Andre receives a severe beating from the locker room girls with a smile on his face.

TV drama

A live-action television drama adaptation was announced in August 2015, directed by Noboru Iguchi at production studio Robot. The series premiered on October 26, 2015, and aired on MBS and TBS. The opening theme song is "Shōdō" (衝動, "Urge") performed by HaKU.

Reception

Over 13 million copies of the manga have been sold as of March 2018. Prison School was one of two winners of the Best General Manga award alongside Gurazeni at the 37th Kodansha Manga Award. The broadcast dub version of the anime was criticized for altering the original meaning of a line while referencing the Gamergate controversy, written by Tyson Rinehart.
