Genres of anime series and hentai vary with the subject to be delivered and what is produced. The content of the series is the one that decides the genre in which a certain hentai falls.

Today, I list the best borderline hentai anime, which will make you doubt if you have watched it. Don’t ask yourself too much about borderline hentai anime because I will make it. By the end of this list, you will be aware.

Let’s start our adventure without wasting much of your time, my fellas. Fasten your seat belts and enjoy the ride as I take you through the list.

1. To LOVE-Ru Darkness

This series is centered on two planets, each with its representatives. The Develuke planet had female members of the royal family as its representatives.

Meanwhile, Earth as a planet had Rito Yuki as its representative. Momo is involved in Rito and Lala’s relationship. The appearance of the Golden Darkness was gonna ruin and make Rito’s life a living hell.

2. High School DxD

This series centers on the main character, who was killed on his first date. It is a perfect series with a sexually tempting genre. This guy’s hobby was a dirty one.

You already know what I’m talking about, right? I can’t imagine how strong the girl was to kill her boyfriend in cold blood. After rebirth, he returned as the head of the house and protected his family. Females were all over him because of his abilities.

3. Yosuga no Sora: In Solitude, Where We Are Least Alone.

Losing both parents due to an accident is something easy, and life is never the same after such incidents. Many themes are portrayed in the series, including lust, love, friendship, and envy.

Hakura and Sora are twins who are now back in their village and living with their grandfather after the great loss of their parents.

Sora is not accepting the whole situation, and it seems she can’t move on. All she wants is her brother’s love. This makes the whole situation complicated as Hakura, by then, had slept with almost every girl in the society. What is Hakura going to do when he gets to know about what his sister wants from him?

4. Show Time!

Despite being censored, this series possesses the traits of a borderline hentai anime genre. It has all the qualities that qualify it to be on this list. A lady named Minami was living a life that was empty, no fun, no what.

Everything changed after meeting a certain man. The rest of you know why I should spoil the fun. Are you looking for a series where one spices up one’s life through the subject of our list today? If so, your search is over, and this will give you great entertainment.

5. Overflow

I don’t have the exact words or the actual words to describe how this series is sexually provoking and satisfying. It is somehow weird and awkward how people are so lewd; how can you think of taking revenge on someone sexually?

Unfortunately, Kazushi Sudo is happy meeting his childhood friends without knowing they have a beef with him. According to the Shirakawa siblings, this was the best and perfect time to teach Kazushi a lesson. However, things didn’t go as planned, as they later started assaulting Kazushi sexually.

6. Shinmai Maou no Testament BURST (The Testament of Sister New Devil BURST)

The series does not have a tangible storyline; it does not have a subject. Despite the clueless series, it is a perfect fit for borderline hentain. It consists of many sex clips and sounds of fantasies in bed.

At first, the series focuses on Basara, who always takes care of his sisters and ensures that the girls are safe. There is only one thing about Basara: he needs to be sexually satisfied to boost his power.

Do you think he is gonna have sex with his sisters to further his power? I can’t tell you because I am somehow disappointed in the way the series is chaotic.

The series failed to deliver its subject and plot; the only reason for this series qualifying to be part of the list is the sex scenes. I’m not judging the characters or underrating this series, but it’s just a mess. What do you think about it? Don’t forget to let me know in the comment section below.

7. Aki Sora (Autumn Sky)

This is one of those series that includes oral sex, which involves someone using their mouth to stimulate their partner’s penis. It also consists of characters having both male and female sexual characteristics, including penises and breasts.

I never imagined Nami would want to have sex with her brother Aoi Aki. If you really wanna get the whole story, then I advise you to read the manga.

It all started with Aoi Sora’s puberty when she found out she had feelings for his brother and started sleeping with him. When Aoi Nami learned about it, she also wanted to have fun.

It is also sad that the sex parts took over the real essence of the story. The sex thing became too much and kinda diverted the audience’s attention.

8. Harem in the Labyrinth of Another World

After logging in to a game he found online, he could not log out again. After logging in to the game, Michio Kaga finds himself in a remote area. He had to fight individuals belonging to a gang and typically operating in an isolated or lawless area.

He could not help after failing to log out and had to accept his new and started to attract women to sexually satisfy himself. His only way of getting money was through overcoming and taking control of underground prison cells.

9. Valkyrie Drive: Mermaid

Are you looking for a lesbian kind of porn anime? Well, this one will drive you crazy. I had never imagined anyone unlocking their powers after being aroused.

Then, that was Mamori; when she was saved by Shikishima Mirei, the island inhabitants started to attack them. They had to fight back to protect themselves, and that is when Mirei kissed Mamori, and she transformed into a sword.

We further see that in this series, for these lesbians to transform into something useful, they had to be sexually aroused first.

They all used to transform into different weapons after a long, passionate, and deep kiss. Even the touching of their boobs also resulted in them turning into guns, vehicles, and swords as well.

10. Redo of Healer

In this series, the main character seeks revenge for the torture and everything that he has gone through before. Through enduring and managing the torture, he was able to get some skills and abilities.

There is a portrayal of some nudity and pornography, especially with his opposite-gender opponents. At some point, he gets strong sexual desires that lead him into doing something that is beyond anyone’s imagination.

His abilities allowed him to rewind time and had healing abilities. So this means that he would hurt you, heal you, and hurt you again. Lol, I’m just saying.

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

This series is majorly concerned with all the immoralities of the devils, and it is clear that the content is all about sex. The anime is not censored, which makes it clear that everything is portrayed as it is without trying to hide anything. The devils don’t care about morality and chastity.

After Lucifer’s defeat, since it was a hero falling to zero, he needed backup to achieve whatever he wanted. He joined hands with Leviathan, who was too enthusiastic to be the Demon King. What else do you expect from two devils? Well, nothing else except a lot of devilish actions.

12. Why the Hell are you Here, Teacher!?

It could have been the most embarrassing situation when Satou ran into Konjima’s restroom. Fortunately, things did not go that way; it was the other way around.

Konjima, our main character’s teacher, has encouraged Satou. When Satou bumped into Konjima in his restroom, there was a spark of something new that no one had ever imagined. It was the beginning of the teacher and student sexual relationship.

13. Ishuzoku Reviewers

This series is full of different species, and there is some kind of competition amongst them. It’s all about which species is the sexiest of them all. It is a word where all races are having sex, and it’s not easy to know about their succu-girl.

This is a demon assuming female form to have sexual intercourse with men in their sleep. In this series, the world seems to be like one big bedroom due to the presence of a lot of brothels of different species.

There is a group of warriors to bring light to the public through some adventures that are just too much, lol. There are different types of girls, some of whom are extremely hot, have elongated bodies, etc.

14. Jin-Rou (1999, movie)

Have you ever watched any anime series and felt on behalf of the characters? Well, this one might even make you cry. It is mainly focused on a constable who goes for retraining after failing a mission that could have also resulted in her death.

She met her sister on her quest to find the suicide bomb. It is so unfortunate that by the time the two were getting close, the conflicts between the police rose.

This series is inappropriate for the young audience as it consists of language that includes dirty words and ideas. It is also full of violence that is intense; hence, viewers’ discretion is advised.

15. Kodomo no Jikan (A Child’s Time)

It is unbelievable how Rin stepped back after taking a gaze at Aoki’s d*ck and saw that it was busy. I somehow fail to understand something here.

Wasn’t she the one seducing and trying to win over Aoki? But Rin is just a child and underage. Does she want her third-grade teacher, or is she up to something else?

Who knows, maybe the girl is really in love with Daisuke Aoki. All this started when Aoki did something for Rin just out of kindness, or, we say, good faith.

Not forgetting to mention that she had quite good skills when it comes to seducing, lol. Where do you think she got those skills? Anyway, forget it; it’s not of concern, right?

Do you think the two are gonna have a fruitful relationship? Let me know in the comment section below if your opinions and points of view matter.

16. World End Harem

I know some of you will disagree with me, but believe me, every man would have loved to live in this world portrayed in the series. This series focuses on three male characters, including the main character, who were affected by a rare disease.

The disease made them fall into a deep sleep for five good years, and to their surprise, when they woke up, they were the only men left. A virus, namely Male Killer, killed all other men who were only killing males.

Now, it’s their responsibility to repopulate the world as they are the only men left. For them to be able to refill the world, they are free to sleep with any woman of their choice. I know someone is like, wow, and envying these guys. Just try to imagine how busy these guys got, lol.

17. Monster Musume: Everyday Life With Monster Girls

It’s always these monsters all over the main character, mostly. This series is based on Kimihito Kurusu’s life, where he attracts non-human female beings.

At this point, Kimihito is living alone; his parents are away, and the caretaker has also left him. These non-human species are now an obstacle in his life because every day they are coming and different types. It is now tempting him to do something that is prohibited.

An experimental marriage is the only way out for him to sleep with these non-human species. It was easy for him because these beings were tormenting him because they were attracted to him.

These creatures were boundless because they were seducing Kimihito and wanted to have a taste of him. Things were getting out of hand, and you all know how it ended. This series portrays different themes like lust, attraction, and eroticism, and it is a harem genre.

18. Elfen Lied

In this series, two people were harmed and injured as a result of torture and experiments by the government. The worst part is that no one would rescue them, so they had to free themselves.

It is not easy, as shown in the course of escaping. A lot happened and made Lucy become what she is now. In the process of running away and escaping from the chains of torture, Lucy suffered a head injury.

The head injury affected her to the extent that she became nothing but a deadly killer. Lucy is naked most of the time during her escape, which gives the nudity concept of this series.

This made this whole thing of escaping to be full of death and loss of life. Keyaru, unlike Lucy, can follow a detailed plan because her mental state is okay.

19. Shimoneta to Iu Gainen ga Sonzai Shinai Taikutsu na Sekai

Have you ever tried pursuing someone, but someone else came your way, and the only way out was to compromise for the one you love? That is the situation Tanukichi Okuma finds himself in, and he has to save his old friend at any cost. Do you think the vice president will let him save his crush?

Everything seems to have changed when new laws concerning sex and pornography were placed in Japan. The government had taken some measures that prevent citizens from breaking chastity laws.

The citizens do not welcome this new policy, hence the rise of terrorists and some other groups revolting against the government. Tanukichi’s father is a well-known and renowned terrorist for spreading lewd content in public.

This drew Anna Nishikinomiya and made it her mission to get close to Tanukichi. She managed to get him into her organization, and they started working together with the same goal of spreading obscene information.

At last, Tanukichi has to do something unimaginable to save his crush. This one is a must-watch, and you will thank me later.

20. Nana (2006, 47 episodes)

How do you see a friendship between people with the same name but different personalities and traits? I’m not saying we are supposed to judge characters, but Nana Osaki is in contrast to Nana Komatsu.

These two characters are the major concern of this series. Despite having the same name, they are two different people. This series contains mature themes and nudity that may harm young audiences.

Nana Osaki is a singer and an independent woman, whereas Nana Komatsu depends on her boyfriend. The two became friends, and their friendship became the center of attraction of this series.
