Unlike the typical moe or generic bishoujo styles often found in high school comedies, Akira Hiramoto employs a gritty, highly detailed, realistic seinen art style. The characters are drawn with distinct features, heavy shading, and realistic proportions (with some notable anatomical exaggerations). The backgrounds are atmospheric, often oppressive.

This realistic art style serves a purpose: it grounds the absurdity. When the characters are sweating in their cells, the detail on the beads of sweat, the darkness of the shadows, and the claustrophobia of the prison walls are rendered with painstaking care. It makes the situation feel heavy and real, which in turn makes the comedy land harder.

The story takes place at Hachimitsu Private Academy, a prestigious, historically all-girls school nestled in the mountains of Chiba. To foster "cooperation between the sexes" (read: save the school from bankruptcy due to low enrollment), the board decides to admit five male students for the first time. Prison School

To the utter horror of the Underground Student Council (USC)—a clandestine, sadistic group of female enforcers—the five boys are not the suave, bishounen gentlemen they expected. They are:

The boys’ crime? Attempting to peek into the girls' bath. They are caught, stripped of their dignity, and sentenced to one week in the school’s notorious Prison School—a medieval dungeon located beneath the dorms.

What follows is an insane chess match. The boys attempt to escape to attend a pro-wrestling event, the Underground Student Council attempts to break their spirits, and eventually, the legitimate Student Council joins the fray. The plot loops through betrayals, cross-dressing, hypnotism, sumo wrestling in a river of sweat, and a conspiracy involving a wet clay statue of a naked princess. The boys’ crime

The narrative is structured in distinct arcs, each escalating the stakes and absurdity.

Prologue & First Arc (The Peeping Incident): Five boys—Kiyoshi, Gakuto, Shingo, Andre, and Joe—are the first male students admitted to Hachimitsu Academy. Desperate for female contact, they plan to peep into the girls' bathhouse. Their plan fails spectacularly, and they are caught by the formidable Vice-President of the Underground Student Council, Meiko Shiraki. They are sentenced to one month in the school’s private prison, where they endure brutal physical and psychological punishment.

Second Arc (The Wet T-Shirt Contest & Escape): Kiyoshi, the protagonist, is offered a chance at early release by the President of the Underground Student Council, Mari Kurihara, to help her undermine the Vice-President. He must sneak out of the prison at night to obtain a photograph that proves Meiko’s sadistic tendencies. This leads to a series of Rube Goldberg-esque disasters, culminating in the infamous "Wet T-Shirt Contest" where Kiyoshi’s plans go catastrophically (and hilariously) wrong. stripped of their dignity

Third Arc (The Cavalry Battle): After the boys are released, the Underground Student Council pits them against the official Student Council in a "cavalry battle" during the sports festival. The winner gains the authority to expel the losers. This arc focuses on strategy, betrayal, and physical endurance, with Chairman’s bizarre obsession with sumo wrestling becoming a key plot point.

Final Arc (The USA Arc): The longest and most controversial arc. The Chairman’s American cousin, Mr. Lee, arrives with his two beautiful but psychotic daughters (Risa and Mayumi) to take over the school. The boys are forced to infiltrate a maximum-security underground prison in a bizarre, neo-noir Western pastiche. This arc is noted for its extreme tonal shift, dragging pacing, and an infamous "urination" scene that tested many readers’ limits. The series ends with a pyrrhic victory: the boys are freed, but their dreams are shattered, and the final panel shows them back where they started—trying (and failing) to peep on the girls.
