14 Anime Like Prison School: Over-the-Top Gag and Ecchi Comedy

Imagine college life but cranked up to the max with absurd drinking games, half-naked dudes, and the kind of humor that leaves you gasping for air.

Grand Blue follows Iori Kitahara as he tries to have a normal university experience. Obviously, he fails because of his new “friends” who are drunk idiots 24/7.

He gets roped into the school’s diving club, which is mostly an excuse for insane drinking contests, wild pranks, and some of the best comedic faces in anime.

Like Prison School, the humor is exaggerated to the extreme, and the characters take their nonsense way too seriously. Their facial expressions are so unhinged they’d make the Prison School cast proud.

Take a world where dirty jokes are illegal, add a masked rebel who fights the system with lewd humor, and you’ve got SHIMONETA.

It’s like Prison School in how it takes perversion and makes it part of the comedy goldmine.

The main character, Tanukichi, gets caught up in an underground movement to restore lewd humor to the world, leading to a string of outrageous situations.

If you love the “weirdly serious about nonsense” vibe of Prison School, you’ll love this one.

Here’s a premise you won’t forget anytime soon: three Yakuza members screw up so badly that their boss forces them to undergo gender reassignment surgery and become idol singers.

Sounds insane? That’s because it is.

Back Street Girls: Gokudols takes absurdity to another level, combining gangster grit with the cutthroat world of idol entertainment.

The result is a nonstop barrage of deadpan humor, exaggerated suffering, and bizarrely heartfelt moments.

It’s the ultimate gag anime, and if you can handle the sheer absurdity, you’ll have a blast watching these reluctant idols navigate their new lives.

For those who want a classic dose of hilarious, over-the-top ecchi adventures, Golden Boy is a must-watch.

It follows Kintaro Ooe, a wandering part-timer who’s either the world’s biggest pervert or its most accidental genius.

This ’90s gem follows him as he takes odd jobs (bike courier, programmer, pool cleaner) and turns every situation into a slapstick disaster.

The humor is raunchy, the life lessons are questionable, and Kintaro’s squeaky bike might haunt your dreams.

It’s Prison School’s spiritual ancestor… maybe minus the prison, plus more accidental peeping. The animation goes all-in on his ridiculous facial expressions as well, making every episode a wild ride.

If Prison School had more supernatural battles and an MC who actively enjoys his ecchi-filled life, it would be High School DxD.

This anime is self-aware to the max, blending ridiculous ecchi humor with supernatural battles and surprisingly fun characters.

The protagonist, Issei, starts off as your average perverted high schooler but quickly finds himself surrounded by beautiful demon girls and angelic rivals.

The show knows it’s absurd and leans into it hard, making it a guilty pleasure for anyone who loves chaotic, boundary-pushing comedy.

High School DxD info (MAL):

Imagine Prison School, but instead of underground punishments, it’s just nonstop dirty jokes.

Seitokai Yakuindomo follows Takatoshi Tsuda, the only male student in a formerly all-girls school, who ends up in the student council.

The student council here runs on pure innuendo, with every conversation devolving into dirty jokes. Instead of normal duties, Tsuda’s constantly bombarded by crude humor and innuendos from the female members.

It’s less about plot and more about how creatively they can twist literally anything into a lewd pun. Perfect for fans who love humor that’s relentlessly shameless.

Now, this one isn’t heavy on ecchi, but its over-the-top intensity makes it feel right at home with Prison School.

Kakegurui is all about high-stakes gambling, where students put their fortunes, and sometimes their dignity on the line.

The absurd facial expressions, wild personality shifts, and extreme tension make every bet feel like life or death.

If you loved Prison School for its dramatic nonsense, Kakegurui offers the same, just with a gambling twist.

Kakegurui info (MAL):

• Alternative Title: N/A

Highschool of the Dead isn’t strictly a comedy, but it’s so over-the-top in its fanservice and action sequences that it might as well be.

Imagine a zombie apocalypse where every movement is a chance for absurd physics-defying fanservice.

There’s slow-motion bullet-dodging (while conveniently bouncing off certain body parts), insane action sequences, and a self-awareness that makes it ridiculously fun.

If you loved Prison School for its mix of tension and comedy, this one delivers a different kind of absurdity but still keeps things entertaining.

This one isn’t just ecchi, it’s full-on uncensored insanity.

Interspecies Reviewers follows a group of adventurers who… review “that” in a fantasy world. Every episode features different fantasy species, absurd situations, and extreme comedy.

If Prison School pushed the boundaries, Interspecies Reviewers obliterates them. Just be warned, this one is very NSFW.

Set in a colorful prison filled with wacky inmates, Nanbaka is a comedy that leans hard into absurdity.

This anime follows four ridiculously strong (but incredibly dumb) prisoners who spend their time trying to escape from a high-security facility. Except the guards are just as eccentric as them.

While it leans more into slapstick comedy than ecchi, the absurd character interactions and hilarious prison antics make it feel right at home on this list.

Think of it as a lighter, sillier take on the prison comedy theme.

Nanbaka info (MAL):

What happens when a man wakes up from a coma and turns out he was actually in an isekai world the whole time?

Uncle from Another World takes the isekai genre and flips it on its head, making fun of every trope while delivering hilarious reactions and misunderstandings.

What I like from this anime is how the Ojisan tries to explain magic… using ’90s Sega references.

His deadpan delivery and flashbacks to his RPG-style misadventures (like accidentally traumatizing elves) make this a hilarious clash of genres.

It’s Prison School’s brand of “awkwardness as comedy,” but with more ice magic and no toilet humor.

Uncle from Another World info (MAL):

The king of parody anime, Gintama is the go-to for absurd comedy. It takes every anime trope and exaggerates it to insane levels, mixing action, drama, and the dumbest humor possible.

One episode could be a heartfelt samurai battle, and the next, a joke about toilets.

While it doesn’t focus on ecchi, it has enough insane facial expressions, slapstick humor, and self-aware ridiculousness to make any Prison School fan feel right at home.

Gintama info (MAL):

• Alternative Title: N/A
• Episodes: 201

If Prison School threw away all restraint and got even more unhinged, it would be Panty & Stocking with Garterbelt.

This anime follows two fallen angel sisters who fight demons in the most inappropriate, crude, and ridiculous ways possible.

The animation style is deliberately chaotic, jumping between sleek designs and intentionally ugly visuals, and the humor is simply crude

It’s like someone took the wildest moments of Prison School and turned them into a full-blown acid trip.

If you love shows that don’t take themselves seriously, this one’s for you.

Panty & Stocking with Garterbelt info (MAL):

• Alternative Title: N/A
• Episodes: 13
• Released: Fall 2010
• Studios: Gainax

A rom-com where the protagonist dates a “gal” (street-savvy fashion queen) and spends every episode freaking out over her boldness.

My First Girlfriend is a Gal is filled with ridiculous misunderstandings, heavy fanservice, and dumb but lovable characters.

The story follows an unpopular guy who unexpectedly starts dating a fashionable “gal” girl, plunging his life into a whirlwind of absurd situations and outrageous comedy.

The humor’s all about cringe-worthy misunderstandings, like accidentally joining a bikini contest or getting caught mid-“private time.”

If you loved Prison School’s “boys vs. girls” dynamic and constant panic sweats, this’ll hit the spot.

My First Girlfriend is a Gal info (MAL):

• Alternative Title: Hajimete no Gal
