Prison School Ova -
Not recommended for minors or viewers uncomfortable with explicit adult comedy.
Unlike typical OVAs that offer beach episodes or filler, the Prison School OVA is canon. It adapts chapters 82 through 89 of the manga, bridging the gap between the end of the "Prison Arc" and the beginning of the "Cavalry Battle Arc."
The plot picks up immediately where episode 12 left off. The boys—Kiyoshi, Gakuto, Shingo, and Andre—have been released from the school prison. The Vice-President (Meiko) has been humiliated, and Chairman Kurihara has decided to forgive the boys for their "crime" of peeping. There’s just one catch: The Chairman doesn’t know the full truth.
To prevent the Underground Student Council (Mari, Hana, and Meiko) from exposing the boys' actual perversions, Kiyoshi and his friends must execute a high-stakes, silent operation inside the Chairman’s office. The goal? Destroy a video recording of their most embarrassing moment.
What follows is 29 minutes of silent film homage, slapstick violence, and the single most visually stunning sequence involving a wax statue, a saw, and a bucket that you will ever see in anime.
Context: Short, punchy, and references the absurdity of the plot.
Text: Re-watching the Prison School OVA and it’s crazy how this show manages to make a high-stakes prison break feel like a mission in Metal Gear Solid, but the objective is just to go on a date. 🤣 prison school ova
The levels of sweat per frame in this OVA are actually illegal. The boys really risked it all for love (and thirst).
We were robbed of a full Season 2, but watching Kiyoshi try to outsmart Hana one last time is top-tier entertainment. 💦🚿

Here is the frustrating reality for English-speaking fans. As of 2024/2025, the Prison School OVA is largely unavailable on legal streaming platforms like Crunchyroll, HIDIVE, or Hulu.
Why? Licensing.
The OVA was produced exclusively as a "manga bundle" bonus in Japan (volume 20 of the limited edition manga) and later included as a bonus disc for the Blu-ray box set. Western distributors (like FUNimation, now Crunchyroll) acquired the rights to the 12 TV episodes, but the OVA fell into a licensing void. Not recommended for minors or viewers uncomfortable with
Because it wasn't technically a "TV episode" but a "physical media extra," the streaming rights were either too expensive to renegotiate or deemed not worth the cost for a niche ecchi title.
Result: The Prison School OVA has become "lost media" for the casual viewer. You won't find it on your standard queue. To watch it, fans must either:
The central plot of the OVA revolves around a specific contest ordered by the USC President. This sequence serves as a microcosm of the entire series: it is ridiculous, charged with sexual tension, and treated with absolute seriousness by the characters. The stakes are raised as the boys must navigate these challenges to avoid expulsion, leading to some of the most memorable and hilarious scenes in the franchise's animated history.
If you have seen the Prison School TV series, the answer is an emphatic yes—with a warning.

To understand why this OVA is essential viewing, you need to know what happens.
After being recaptured for the peeping incident, the boys are thrown back into hell. However, Chairman Kurihara (Mari’s cross-dressing, wrestling-obsessed father) has a new, sadistic punishment in mind. He organizes a "Shadow Bokuto" (A water-based cavalry battle) in the school's outdoor pool.
The catch? The boys must wear ridiculously thin, white school uniforms that become transparent when wet. Their opponents? The entire Upper Student Council (covering the school in soap) and, most dangerously, the Underground Student Council—Mari, Hana, and Meiko—also wearing dissolving white tops.
The OVA focuses on two primary conflicts:
The episode ends not with a resolution, but with Kiyoshi realizing that to save his friends, he must literally "lose his mind." It sets up the Calvary Battle Arc perfectly but leaves viewers screaming for more.
