31 Borderline Hentai Anime of All Time

Borderline Hentai Anime

There are many ways to describe anime content, from shounen to shoujo to hentai

These descriptions are broken down into so many sub-categories that it is difficult to track.

Some are redundant or not used in other countries like Japan. 

Ecchi anime and borderline-hentai anime are two examples of such categories. 

There is not a category called “borderline Hentai”, and it’s not used by any anime-related websites. 

A show that has a lot of fanservice is called an “ecchi anime”.

However, some shows exceed the boundaries of what can be shown while keeping the hentai brand in mind.

These anime are known by fans as borderline-hentai.

This is how it should look: You can imagine yourself watching an ecchi anime that is so outrageous, you have gone into puberty and maybe gotten a few chest hairs.

This, dear viewer, is borderline hentai animation.

But, we have an updated list to help visualize what it feels like when you hit puberty.

Mnemosyne: Mnemosyne no Musume-tachi

The show features a central persona of Rin Asogi, who has acquired immortality and can solve crime with the assistance of her immortal companion known as Mimi. 

In her lengthy life, she was victim to different kinds of torture and even murdered, but she was able to resurrect the world thanks to her immortality.

Sekirei

Although Sekirei is a highly enjoyable and entertaining show, the women on the show are portrayed as objects of ridicule and prizes that could be perceived as offensive. 

However, it tells the story of alien beings that kiss people with certain genetics. 

Following the kiss, humans acquire powers, and they become stronger.

Sekirei is about this extraterrestrial being called Musabi who aids a child known as Minato Sahashi after he failed in his examinations. 

There are a lot of explicit scenes that make Sekirei an adult-only content anime.

13. Blade of the Immortal

Blade of the Immortal

The plot has deep ideas and a distinct character in Manji’s form.

Manji but, most importantly, there’s plenty of violence, s*xual s*x, and other horrific details that make it a worthy entry in this category.

12. Nana

Nana

Nana certainly has a mature storyline that involves some s*xuality and concepts that aren’t suitable for a younger generation to understand. 

The story tells the story of two women who share the same name.

While one of them is Nana Komatsu, a woman dependent on her boyfriend, the other one is a rock star with a strong name, Nana Osaki.

11. Jin-Rou

Jin-Rou

It’s certainly not aimed at the young crowd and features a captivating story that can make you feel the characters. 

The film tells the story of an officer named Kazuki Fuse who could not shoot a suicide bomber.

Due to his inability, he was forced to undergo training. 

He set out to find the suicide bomber, and also met her sister.

10. Amai Choubatsu: Watashi wa Kanshu Senyou Pet

Amai Choubatsu: Watashi wa Kanshu Senyou Pet

Let’s begin our list with a new type of anime.

These 1-2 episode OVAs are cut up into bite-sized episodes and broadcast on public television.

The uncut version is also available on the internet or DVD/Bluray physical releases. 

Amai Choubatsu Watashi Wa Kanshu Senyou Pet is one example of such an anime.

It tells the story of Saotome Hina, who was convicted of embezzling millions from a company and is sentenced to one year. 

She is the only female prisoner and is often targeted by inmates.

Myoujin Gakita, the chief security guard, also targets her for s*xual pleasure.

Amai Choubatsu, a short smut animation in which Hina is subjected to many s*xual acts and ultimately likes it, is a short smut manga. 

These s*xual torture scenes will only be seen in the R-18 anime.

The all-ages version is just as kinky, but there are many jump cuts.

Fun fact: Japanese youths enjoy cosplaying as Schutzstaffel officers.

The uniforms look great, especially when they are holding a whip. Maybe it’s a fetish being abused by handsome Nazi soldiers that will make your heart scream.

9. Sin: Nanatsu no Taizai (Seven Mortal Sins)

Seven Mortal Sins

God cast Lucifer, the archangel Lucifer from heaven for her prideful and rebellious ways. 

Lucifer was sent to Hell where she meets the Seven Deadly Sins and the Seven Demon Kings of Hell. 

Lucifer is cursed by one Sin during her struggle in Hell and she retreated to the Human World where she meets Maria, a young girl. 

Maria wanted her to become Lucifer’s servant, so she did.

Lucifer and Levi must fight against demon kings, and Lucifer must also be freed from a curse.

Sin: Nanatsu No Taizai is often compared to Queen’s Blade.

However, there are many similarities between the two animes. 

Sin: Nanatsu No Taizai, despite its hentai nature and recently, is just as lewd as Queen’s Blade. 

Scantily-clad women warriors? 

Check. Check. Check. 

Do you see any scenes that make it difficult to look around and see who else is there? 

Double-check. This anime will be a hit! It’s not for the story.

8. Masou Gakuen HxH (Hybrid × Heart Magias Academy Ataraxia)

Masou Gakuen HxH

Interdimensional machines have invaded Earth, forcing the surviving human species to flee to the ocean.

Since then, humanity has been developing new technologies such as the Heart Hybrid Gear, to fight the invaders. 

Hida Kizuna is the protagonist of the story.

His sister has called him to enroll in the Strategic Defense Academy Ataraxia. 

Why was Kizuna called to the academy? 

What is it to do with his past?

The anime’s opening scene features an aroused girl performing a lap dance.

This will let you know that it isn’t for everyone. 

Masou Gakuen HxH, an action sci-fi series, takes its cues from Valkyrie Drive Mermaid.

This anime features girls who are s*xually aroused to gain superhuman abilities and fight against an alien race of machines that threaten Earth. 

Hida Kizuna, our hero, can provide the energy necessary to power the Heart Hybrid Gear power suits. 

The girls will get more pleasure the more they receive power. 

However, just touching their breasts is not enough to increase their power output.

Kizuna must be imaginative with his limbs. They are all five.

7. 25-sai no Joshikousei

25-sai no Joshikousei

This is how it happened: Natori Hana (25 years old) was convinced by her aunt that she would attend high school instead of Kaho her cousin because teenagers are cool. 

It would have been fine since Hana and Kaho are identical, but unfortunately for Hana things did not turn out the way she expected. 

Kanie Okito, a former classmate, has become a teacher at the school.

He saw through her mask. Hana should not worry, Okito assured her he wouldn’t reveal her identity…

Another smut anime, like Amai Choubatsu.

The anime is available in two versions: the all-age and uncut versions.

Your mileage will vary depending on which version you have watched. 

The all-ages version has Hana being seduced by the admittedly handsome teacher.

This involves kissing and caressing. 

The uncut version is just that: the teacher loves the “two-finger salute.”

Let your imagination run wild.

6. Omiai Aite wa Oshiego, Tsuyoki na, Mondaiji

Omiai Aite wa Oshiego, Tsuyoki na, Mondaiji.

Saikawa Nano, a high school teacher, has set up a marriage interview for Takamiya Souichirou’s friend. 

Nano initially resisted but soon became enamored of the handsome, well-mannered Souichirou.

The two eventually got into bed together. 

After a few exchanges with saliva and probing their bodies, Nano was stunned to discover that the man she is falling in love with isn’t Souichirou but her younger brother Souji. 

That’s awkward.

Short smut anime is a recent trend and may become a popular anime genre in the future. 

The story and pacing of Omiai Aite are very similar to 25-sai No Joshikousei.

However, the roles are reversed.

This time, the guy is the student, and is in a romantic relationship, with his female teacher. 

Nano discovered that Souji, her student, had posed as an arranged bachelor and Souji has the rights for her.

Then, her school life as a teacher will be completely different. 

The Clark Kent Disguise routine was surprisingly successful, it seems.

5. Monster Musume No Iru Nichijou (Everyday Life With Monster Girls)

Monster Musume No Iru Nichijou

Monsters exist and are already living with humans. They were able to pass the Interspecies Cultural Exchange Act.

All kinds of mythical and beastly creatures are allowed to live with human families to adapt to human society. 

Kurusu Kimihito, one of these hosts, lives with Miia (a half-human, half-snake being who is madly infatuated with our hero). 

Kimihito, as host of Miia, must do all he can for Miia to adapt to her new environment. Our hero is the kindest and generous man on Earth.

Agent Smi-Ms. Kurusu has attracted more monster girls to Smith and they now live with him. 

Are they the luckiest or least fortunate men on Earth?

Monster Musume can be considered an alternative to harem animation. 

Are you tired of harem anime that has a lot of beautiful girls falling in love with the main character who is a loser but still cares? 

What about a harem manga featuring tons of beautiful monster girls falling in LOVE with an attractive main character? 

BAM! 

You get Monster Musume. It’s the little things in life that make all the difference!

Monster Musume is a kind of ecchi anime.

However, the stories are centered around the unique characteristics of the monster girls living in the Kurusu Family. 

Kimihito must be careful with these monsters because they are based upon certain creatures.

4. Aki Sora

Aki Sora

Aoi Aki and Aoi Sora were close siblings who shared an intimate bond as children. 

Aki realized the truth about her feelings for her brother Sora during puberty and they eventually fell in love. 

Aki and Sora share another sibling, Aoi Nami. And wouldn’t it surprise you, Nami wants to be a part of the action.

Aki Sora is a well-known manga, for both the right reasons and the wrong. It was a series about incest that featured a lot of explicit s*x scenes and s*xually suggestive scenes.

Bill 156–Tokyo Metropolitan Ordinance Regarding Healthy Development of Youths was passed to affect the series.

The publication had to stop the series from airing sooner because of its explicit incestuous nature. 

Aki Sora had an anime adaptation and a sequel before the bill was passed. Both are very raunchy and contain plenty of s*x scenes. 

Comparable to modern hentai, the s*x is more controlled. It shows characters pushing during s*x but doesn’t show actual penetration or genitalia. 

This, along with other factors (loopholes within rating titles), prevented AkiSora from being classified as hentai.

However, AkiSora was still able to be extremely s*xually explicit featuring a group of young people who are some of their blood relatives having s*x and other indecent activities.

3. Skirt no Naka wa Kedamono Deshita

Skirt no Naka wa Kedamono Deshita.

Kominami Shizuka, a shy and conservative college girl, went to a college mixer to meet other students and maybe get rid of her anxiety around men. 

Shizuka meets Kirishima, a tall, beautiful, mature woman. 

They fell in love with Ryou’s beauty and spent the night drinking and talking. 

Ryou, after too many drinks, takes Shizuka to her apartment to seduce her. Ryou is a cross-dressing male.

Another anime series featuring “lady porn”, which is geared towards women. The core story revolves around Shizuka’s rape and her development of Stockholm Syndrome towards Ryou.

However, the anime is more concerned with titillating viewers than telling the dark story about women who have been abused. 

Skirt no Naka offers two versions of Skirt no Naka: the all-ages version, which is lewd-free and s*xually suggestive but not for everyone, and the R-18 online version.

Both are available in official BD releases. 

The all-ages version is suitable for those who don’t mind s*xual abuse.

However, the R-18 version will delight those who love danger and excitement.

2. Joshiochi! : 2-kai kara Onnanoko ga… Futtekita! ?

Joshiochi! : 2-kai kara Onnanoko ga... Futtekita! ?

Aikawa Sousuke, a part-time worker, is a typical guy.

He was fortunate enough to share a rundown apartment with Yuki, the landowner, and Sunao, the attractive woman who lives in a room above Sousuke. 

Sunao fell through the hole and Sousuke’s ceiling gave way on a sunny day. 

Sunao fell with Sousuke’s penis…in her vagina…Thankfully, Sousuke was quick to his feet and cushioned Sunao.

This is the basic premise of the show. Each episode runs approximately 3 to 6 minutes. 

Each episode features our unfortunate hero Sousuke, who often gets into unfavorable situations.

This usually leads to him getting in trouble with women because he lacks self-control. 

Scenes of girls getting horny and showing off their skin are some of the scenes.

There is also some dirty dialogue that will make Joshiochi laugh! 

This anime was borderline hentai and was televised. It’s not over, dear reader! 

This is the all-ages version of the one you just saw!

The second uncut version of Joshiochi is just like Skirt no Naka Wa Kedamono deshita. 

It contains all the s*x scenes removed from the all-ages version and goes literally “in-depth” about what happened after Sunao fell from the ceiling and landed on Sousuke. 

It was extremely, very kinky. It’s not clear how Sunao landed perfectly on top of Sousuke, but Joshiochi, it is now! 

This anime series has a quirky personality that only the most dedicated fans are aware of. 

One piece of advice: Do not try to do what Sousuke did. It will only lead to you breaking your… uh?… thing.

1. To Love-Ru Darkness

To Love-Ru Darkness

To Love-Ru Darkness continues the story of Yuuki and his adventures with Lala Satalin Deviluke, an alien from another planet.

It also features a large cast of beautiful girls who have romantic feelings for our hero. 

In Darkness, Lala’s sisters Nana and Momo have moved into Earth to be with her and cause havoc to Rito as well as everyone else in the area and school. 

Their presence increases Rito’s chances of Rito slipping and grabbing the undergarments and getting a look at their bodies.

However, Momo has other motives. He wants Rito to start a harem if he wants the title of the ruler of the universe.

To Love-Ru was a harem anime show that defied the rules. 

To Love-Ru’s first adaptation was a standard ecchi anime harem, covering all fetishes from vanilla fanservice, aliens, and tentacles.

But it wasn’t until To Love-Ru Darkness, the third season, that we saw a shift in fan service delivery.

Fan service is now more deliberate, with constant boob, panty shots, and a lean toward the s*xual type, often involving Momo’s plan for creating a harem, which is shown on the girl’s. 

There are many close calls, such as Rito’s hands reaching for the girl’s intimate parts and scenes that involve Rito kissing Rito on the manhood.

The manga series moved to Jump Square and changed its target audience from younger teens to adults. 

It shows as Darkness’ fanservice has some of the most inappropriate scenes in the entire series.

Last Thoughts

The list ultimately boils down to one question.

Can a series entertain, have a great story and provide the best tier of ecchi fanservice while also being entertaining? 

Some anime have explicit scenes, such as s*x scenes, or scenes featuring crotch shots.

However, these episodes were short in length, which makes it difficult to develop a connection to the characters and story. This is the literal meaning of “anything”.

To Love Ru Darkness has all these qualities, which is why To Love Ru is a favorite among fans. 

Rito is a bumbling idiot who can trip on girls with incredible skill, but he also has a heart full of gold and is a caring person. 

Every girl in Rito’s life has a unique personality and has their own story to tell. Momo is interested in creating a harem but has personal feelings toward Rito. 

Nana is self-conscious about her bust and is often teased by Momo. However, she is a friend who protects her. 

Yui is strict about school orders, but she sometimes has trouble controlling her feelings towards Rito, her childhood friend. 

These are just a few examples of how different each girl can be. The anime has all the episodes needed to tell their stories. 

To Love-Ru Darkness, a borderline hentai animation that isn’t offensive to its fans but still gives you a good time is the best.

That’s it! Let us know what you think. Did we leave any borderline hentai out? Please comment below, as always, to share your thoughts!
