Top 10 Borderline Hentai Anime [Best Recommendations]

También puedes leer este artículo en: Español

If my memory served me right, Anime took a huge leap and poured out nudity or sexual explicity themes that’s normally restricted to direct-to-video OVAs, movies or even Ero Anime/Hentai in the 2000s. Or did I miss the memo that anime had been doing this since forever?

Whatever the case is, nudity and sex is part of anime and one of the traits that differentiates itself from Western anime. Don’t get me wrong, there are some pornographic cartoons out there, but in terms of scope, anime beats the West 1 quintillion anime with nudity to 1. And yeah, I made those statistics up.

So yeah, if you look at, say, this season’s list of anime, you’ll see a bunch of fanservice-centric shows and they’re so common, we often don’t mind because that’s how anime is — blurring the line of what is okay or not okay for public broadcast. And every now and then, an anime show, uh, shows up and dared to lean over to the hentai category.

In this list I’m going name 10 anime shows with fanservice that may be considered too lewd for public broadcast. Flashing bare boobs and panties does not count. What counts are scenes or acts that leans too close to pornography. Or to put it simply: Scenes that makes you wonder: “Is this porn?”

10. Kanokon (Kanokon: The Girl Who Cried Fox)

  • Episodes: 12
  • Aired: April 2008-June 2008

Oyamada Kouta is a country boy that moved to the city to attend high school. His life changed quite chaotically as he encountered Minamoto Chizuru — a well-endowed fox spirit… girl. As typical as anime goes, Chizuru finds Kouta very attractive and spared no expense trying to seduce him. Things get more chaotic after the two attracted a wolf spirit named Ezomori Nozomu.

With two supernatural entities around him, trouble is bound to happen — Kouta is involved in many supernatural events. Kouta’s high school life will never be the same.

Let’s start with something, uh, light, I suppose. Kanokon doesn’t have any sex scenes of any sort, but it does have some very lewd moments involving Chizuru intentionally, or unintentionally, seducing our short hero Kouta. Now that may sound pretty normal in a harem anime and it’s not borderline, but the detailed artstyle made each scene look way too detailed to simply be just for comedic purposes. Tap that ass, Kouta-kun!


9. Kiss x Sis

  • Episodes: 12
  • Aired: April 2010-June 2010

Suminoe Keita, Suminoe Ako, and Suminoe Riko are step siblings after their parents remarried. Since this is a romance-centric anime, the sisters are very attracted to our hero in a very, very, very, VERY lustful way.

Initially Keita avoided his sisters’ advances since he thought it wasn’t right to get so—romantically involved with his new family. Things changed after Keita transferred to the same school as his sisters. He’s slowly getting attracted to them.

You’ll probably see a few more incest-centric shows in the list, so I’ll start with Kiss x Sis. Keita is getting pampered by his step-sisters way too much that they’re almost sexual. Keita sometimes try to avoid any intimate contact with his sisters but like any other young man, he can’t suppress his urges all the time.

Fanservice usually range from the three in a bathroom together, the three in Keita’s room, or doing some lewd things in a karaoke room drunk. Now you may think this is normal like any fanservice show, but the anime takes a step further to make the scenes borderline hentai. Like Keita getting pinned on the bathroom floor with his clenched hand on top of one of the twin’s crotch, his hand loses grip and fingers slide over the crotch one by one. Yeah, I know, Keita is one lucky basta—fella.


8. Queen’s Blade

  • Episodes: 12
  • Aired: April 2009-June 2009

The Queen’s Blade tournament is held every four years to determine the most beautiful and powerful Queen. Enter Leina Vance, the heiress of the Vance Family and next in line for the throne, who is seeking the title of Queen. As she travels the land of Gainos, she meets other warriors from various lands also seeking the title.

Queen’s Blade is a fanservice show with the intent of titillating the viewers. You are bombarded with boob shots, jiggle boob shots, pantie shots, wardrobe malfunctions, and raunchy scenes ranging from sexually suggestive strangle holds; like girls drooling or getting aroused, sexual poses (seriously, a nun posing for a crotch shot), bare breast groping, and borderline yuri rape.

Despite its effort in telling a story, Queen’s Blade’s main selling point is seeing these busty girls do some lewd things unintentionally. Or were they intentional? Anyways, Queen’s Blade is still a fanservice show that crammed every possible fetish in one thick package.


7. Highschool DxD

  • Episodes: 12
  • Aired: January 2012-March 2012

Hyoudou Issei and his two friends are a trio of boys who, I think, just reached puberty — They can’t stop thinking about girls’ breasts and their 3 sizes. Unfortunately for them, they’re all spineless at talking to girls and the entire school sees them as perverts. On a typical day, Issei got lucky when a girl confessed her feelings and like any desperate guy, our hero accepted the girl’s confession (whom he just met, by the way) and started dating.

Things turned for the worst for Issei when the girl he was dating is actually a fallen angel sent to kill him. Issei was killed by a stab to the chest, but he was revived by a beautiful redhead girl named Gremory Rias, and he became her servant.

Season 1 doesn’t have that borderline hentai lewdness, but things get raunchy in Season 2 and Season 3 with the girls trying to get into Issei’s pants, and then conveniently interrupted. It’s like they’re putting a stop sign telling the anime that’s far enough. Your mileage may vary depending if you like our perverted, yet capable hero, Issei.


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

  • Episodes: 12
  • Aired: January 2015-March 2015

Father and son Toujou Jin and Basara is gonna have company, or rather, more family members. Jin is finally getting remarried and and wouldn’t you know, Basara has now two cute little sisters Naruse Mio and Naruse Maria!

After unexpected news, Basara’s father got a call and will travel outside the country, thus leaving Basara with his new step sisters all alone. After their father left, Basara was shocked to see Maria a succubus and Mio the daughter of the Demon King! And here’s another twist, Basara has supernatural powers as well!

The entire premise is another occult fantasy involving demons set in a slice-of-life style scenario. After knowing Mio and Maria’s situation, Basara must do whatever it takes to protect Mio from the demons that are sent out to kill her. Where is the lewd, you ask? Maria is a crafty little devil that tricked Basara and Mio to form a master-servant ritual, thus making Mio’s body into arousal overload if she becomes disobedient or anything the plot finds convenient. In order to suppress this, Basara must perform, uh, you know, body massage.

Things get intense with Maria’s antics, and Basara discovering he needs to grope and suck on the girls to increase his power. Thankfully for Basara, he has a servant and a harem.


5. Seikon no Qwaser (The Qwaser of Stigmata)

  • Episodes: 24
  • Aired: January 2010-June 2010

Oribe Mafuyu and Yamanobe Tomo rescued a wounded boy without realizing what they were getting themselves into. The boy is named Alexander Nikolaevith Hell and he is a Qwaser, a kind of superhuman who can draw the power of elements and use them as powerful weapons, as the fate of the world hangs in the balance. The bizarre twist is that the Qwasers require a special kind of liquid to recharge their powers and this liquid is none other than breast milk.

The premise is similar to Valkyrie Drive: Mermaid in terms of the usage of nudity or fetishtic acts as part of the central main plot. Alexander “Sasha” and similar warriors needs to extract Soma, a special essence, found in women’s breasts to harness the power of the elements. The potency of the Soma depends on the individual, so Sasha must take it from someone with a set of qualities.

Ah, fetishes.


4. Kodomo no Jikan (A Child's Time)

  • Episodes: 12
  • Aired: October 2007-December 2007

Daisuke Aoki is a 3rd grade teacher who meets Kokonoe Rin, a very young girl with long hair. After an act of kindness from Aoki, Rin made Aoki, her teacher, her lover. Rin literally wants her 3rd grade teacher to be her lover. Who would have thought that your biggest obstacles in your life comes from the most unexpected places. But is Rin’s love for Aoki really true? Are her feelings just puppy love? Or is it genuine true love? Does actively seducing Aoki mean something else?

Think of a school romance with the girl falling in love with her teacher and the girl actively seduces the teacher like peeping under her skirt with panties down, or crawls on his bed naked without him knowing and the girl backed off because the she realized it was too big and won’t fit? And what if I say the girl is an underaged loli? Yeah… This is Kodomo no Jikan.

But behind the fap-bait-like premise involving a developing sexual relationship of a grown man and a very young girl, lies an intriguing story of love, sadness and acceptance.


3. Valkyrie Drive: Mermaid

  • Episodes: 12
  • Aired: October 2015-December 2015

Tokomome Mamori is a special kind of girl who was transferred to a mysterious island chain in the middle of the ocean in the most unconventional way. The young cast away was suddenly attacked by the island inhabitants, but then was luckily saved by a girl named Shikishima Mirei. As their assailants pressed on with their attack, Mirei suddenly kissed Mamori, and Mamori turns into a sword!

This is a blatant softcore lesbian porn and the anime doesn’t even hide it. The main gimmick/theme/selling point is the girl-on-girl acts, Liberators, needed to perform to activate their partner, the Exters, into weapons of mass destruction ranging from guns, swords, and even vehicles. You see, the Exters needs stimulation in order for them to transform and the best way to do it is for their Liberators to perform various deeds like French kissing, groping of the breasts, caressing of the body and stroking, or inserting fingers to their partner’s privates. And this is not a one time thing, you’ll see a lot of them throughout the show. The anime even went further by adding a tentacle rape scene, but it’s tame enough to avoid the R18. Nice, Japan.


2. Aki Sora (Autumn Sky)

  • Episodes: 1
  • Aired: December 2009

Aoi Aki and Aoi Sora are a pair of close siblings that shared a strong intimate bond when they were young. During their puberty, Aki finally realized her real feelings towards her brother Sora, and eventually they made love. Aki and Sora have another sibling, Aoi Nami, and wouldn’t you know it, Nami wants a piece of the action.

Aki Sora is a modern anime that feels like a hentai show that depicted a lot of sexual acts ranging from fellatio to futa fantasies. Personally I enjoyed the anime when it first came out, but after watching the follow-up Aki Sora: Yume no Naka, I’ve grown to dislike the anime. I’m not sure why, really. Maybe I don’t like the older girl and short younger guy thing, or they ditched a good chunk of the story and replace them with lengthy sex, or the story was just overall sad.

The story had no conclusion, so if you wanna see the story of Aki, Sora, Nami, and their sexual development, you need to read the manga.


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

  • Episodes: 12
  • Aired: October 2010-December 2010

Yosuga no Sora is one of the recent modern anime to depict actual sexual acts on screen involving two blood-related siblings. The anime starts off with the twins Kasugano Sora and Haruka returning to the countryside to start a new life after their parents died from a freak car accident. There they meet with childhood friends and their new life began, but little do everybody knows that the twins carry a secret and forbidden relationship behind closed doors.

The anime, for the first half at least, is your typical visual novel adapted anime with lots of supporting characters that are potential love interest for Sora, but then the anime suddenly took a nosedive to focus on the incestuous sexual relationship between the siblings. There are no multiple arcs, or fillers — Yosuga no Sora tells the story of a pair of twins’ bond, love and sexual discovery. Oh yeah, the anime’s most memorable scene is probably this: One of Sora’s friend caught the twins having sex in their home’s front entrance, and it took Sora a few seconds to notice someone in front of him while continuing pounding his twin sister. Eh, the phrase “my hips are moving on their own!” really fits here.

What makes this number 1? Simple: It has actual sex albeit in a softcore kind of manner with no visible penetration and genitalia, the couple are blood related, and it was aired on local TV. Aki Sora had more sex per minute and there is incest as well, but it was in OVA format, so it made a little impact on how anime almost crossing the line on what’s porn or not. Yosuga no Sora was heavily censored on local TV, but the sexual acts are still there. And hey, they need to sell their DVDs with uncensored content to sell, right?


Conclusion

The question is why are shows that aired on TV which have sexual acts not branded as hentai and not restricted to home video? I have no clear answer to that, but one thing’s for sure, Japan has the R16 rating that is below R18, and above Teen. All anime with clear depictions of upper nudity, sexual situations, and acts with no visible penetration and genitalia are rated R16, a rating that is below R18 and above Teen in Western ratings.

It’s probably a culture thing. Japan has their own depictions and views of sex than the West, so when these shows are localized, they fall to the R18 category because R16 or something equivalent doesn’t exist.

So, yeah, there you have it! What do you think of the list? Do you know any more anime that you think are way too lewd? Please leave a comment below!
