We’re kicking this list off with a perennial treasure trove of ecchi content, No Game No Life. Despite the much-maligned release schedule, the light novels are still excellent (as were the visual-acid-trip anime and movie), and definitely have the ecchi content you’re looking for!

Brother/sister team Sora and Shiro have an abnormally close relationship, so if you’re looking for some siscon ecchi, you’re in luck. Volume 1’s in-flap artwork showcases Shiro and traveling companion Steph completely nude, so you know what you’re getting in for before the very first page!

There are also plenty of boob gags and pervy content along the way, usually at poor Steph’s expense, thanks to the nature of the “game world” that governs this semi-isekai story. No Game No Life is so ecchi it was infamously banned in Australia (this writer’s country), so that’s a recommendation in itself!

From siscon to momcon?! For our shameless MILF lovers, you’ll love the yummy-mommy content of Tsuujou Kougeki ga Zentai Kougeki de Ni-kai Kougeki no Okaa-san wa Suki desu ka? (Do You Love Your Mom and Her Two-Hit Multi-Target Attacks?). Teenager Masato battles an Oedipus complex when he’s sucked into an MMO with his unusually young, vibrant, and extremely busty mother, Mamako!

For the reader, that means more boob gags than you can shake a stick at, with a Freudian complex for Mamako’s mama milkers! It’s best not to take this series too seriously, but thanks to Masato’s inner monologue, the ecchi content is funnier and just a bit smuttier than the anime adaptation — so it’s worth a second look if you already watched the adaptation!

Billed as a “Psycho Love Comedy”, Psycome is one of the rare stories with an actual yandere (crazy with a capital ‘C’) love interest. Sentenced on false charges to a “rehabilitation school”, main character Kyousuke finds himself surrounded by punks, thugs, and — gorgeous girls?! He mistakenly attracts the affections of the hugely busty Renko…but if he ever allows himself to fall in love with her, she’ll remove her infamous gas mask, and murder him!

Of course, Renko will do everything in her power to make Kyousuke fall for her, including using her ample assets to her advantage! Cue a plethora of panty-shots, accidental boob-face-plants, and some truly wonderful artwork from the series’ artist Namanie! If you’ve been hunting for a sexy yandere female lead, Psycome might be just the right “punishment” for you!

Released six years after its Japanese debut, Rakudai Kishi no Eiyuutan (Chivalry Of a Failed Knight) offers a pretty standard tsundere female lead and a hopeless-but-strong-willed male main character. Set against the backdrop of “mage-knight” combat, our main characters must work together as magicians and knights to rise to the top of their school’s academy!

Essentially a more ecchi Asterisk War, Chivalry of a Failed Knight picks up a win on our list for constantly finding ways to put leading lady Stella in compromising positions, while also developing an actual relationship with her seemingly useless knight, Ikki. Being forced to live and work together creates some good tension and steamy moments, and Won’s artwork brings Stella’s magic — and body — to life in beautiful illustrations.

From having the weakest skill in a new fantasy world, main character Hajime grows to become a god-slayer with a harem of uniquely beautiful girls — and the original light novels are excellently ecchi in that regard. From having “intimate” relations with pint-sized Yue, to fending off the advances of the busty bunny girl Shea, Hajime has his hands full of trouble! (Metaphorically full, of course. Yue might be a powerful sorceress but she’s…a little lacking in the chest department…)

That’s to say nothing of Tio, a shape-shifting dragon who puts the horny in “horned dragon”, or Hajime’s old classmate and crush, Kaori. Eventually, a polyamorous relationship forms among the harem; so everyone ends up a winner (but mostly the readers)!

This is a sugary-sweet romance with a twelve-year age gap between high-schooler Momota and his office-worker girlfriend, Orihara! Both clueless in love, this earnest couple have to navigate societal expectations and their own unique clumsiness in the world of romance!

Orihara has the oppai of your dreams, and her awkward stabs at a relationship include some hilariously ecchi moments like preparing for the “first time” staying over with her boyfriend, or trying to find a swimsuit that’ll fit her ample bosom. Choppiri Toshiue Demo Kanojo ni Shite Kuremasu ka? (Are You Okay With a Slightly Older Girlfriend?) tends to focus more on the actual relationship in this age-gap without delving too deeply into drama, so sit back and enjoy this simple ecchi rom-com!

After a messy breakup, the last thing Mizuto and Yume want is to ever see the other again… but when their parents remarry, this ex-couple finds themselves sharing a house, and a surname! The bitter feelings from their failed relationship still remain, but their attraction to each other is also still there, now heightened thanks to the “taboo” of their step-sibling relationship.

Less overtly ecchi than some of the other entries on this list, Mamahaha no Tsurego ga Motokano datta (My Stepmom’s Daughter Is My Ex) has a lot of steamy moments as Mizuto and Yume realize they still have feelings for each other. There are some great scenes like stealing the other’s underwear, or going too far with accidental run-ins after a shower — so this is definitely worth a read, especially if you want a romantic drama as well.

When you think “dating sim reincarnation”, you’re probably thinking of soft shoujo otome isekai novels with elements of magic or drama. Well, how about an ecchi fantasy where a male character gets reincarnated into an erotic dating sim?! Welcome to Magical☆Explorer – Eroge no Yuujin Kyara ni Tensei Shita Kedo, Game Chishiki Tsukatte Jiyuu ni Ikiru (Magical☆Explorer: Reborn as a Side Character in a Fantasy Dating Sim)!

Magical☆Explorer, despite its premise, is a lot less ecchi than you might imagine, and focuses more on the dungeon exploration and magic than the eroge elements. That said, there’s some truly hilarious commentary on players of these adult video games, along with some excellent artwork and ecchi tropes. In all fairness, Magical☆Explorer is actually a much better story than its title and premise would suggest, so check it out when you have the time!

Finally limping its way to an official English release some twelve years after its Japanese debut, the legendarily ecchi series High School DxD immediately got banned in this writer’s home country (Australia), which, if you haven’t noticed, is starting to form a bit of a pattern. Saltiness about certain Australian senators aside, we can happily recommend this aging classic thanks to its unabashed ecchi-ness.

Even a decade or more after its release, including spin-off manga and novels, and an anime that sadly got censored in the later seasons, High School DxD remains a classic ecchi fantasy. With superb, fully uncensored artwork, and a story that manages to weave drama, magic, and ecchi together, it’s pretty hard not to recommend this classic — even if it’s starting to show its age just a bit.

All the way from the euphemism in the title down to the impeccable artwork, Ore Dake Haireru Kakushi Dungeon: Kossori Kitaete Sekai Saikyou (The Hidden Dungeon Only I Can Enter) is a masterclass in modern ecchi fantasy. Complete with a dungeon-crawling setting and a rags-to-riches main character with cheat skills, the ecchi humor truly elevates this light novel above other harem isekai.

There are plenty of ecchi moments we love in The Hidden Dungeon Only I Can Enter, from passionate kissing having the ability to restore mana, to using cheat skills to alter girls’ boob sizes. Coupled with a genuinely fun story and some cool magic, you’ve got an entertaining and modern ecchi isekai that pushes the envelope, but never at the expense of its enjoyment!

What would you do if an alien ended up meeting you? Even more so, what if that alien was a super cute cat girl?! Kakazu Kio is about to have this exact event befall him when he meets Eris. However, this incredibly cute cat alien girl has a lot of baggage as it seems a lot of people want her. How can Kakazu possibly keep Eris from becoming a test subject when he’s nothing more than a high school boy?

Cat girls and more than one, Asobi ni Iku yo is the best way to start our ecchi light novel list. While Asobi ni Iku yo seems overly silly, this odd sci-fi romance story is really fun and hooking thanks to Kamino, Okina excellent banter between characters and strong descriptions. Every ecchi scene we know readers can visualize even without illustrations at times. When there are page breaks two artists—Houden Eizou, Nishieda—do a great job showing off various scenes. While the anime from Asobi ni Iku yo is great we know you’ll enjoy the light novels even better in this ecchi tale of cat girls and aliens.

Amusement parks are supposed to colorful and brilliant, places that you can go with friends, family and maybe even that special someone. Unfortunately, no one would want to visit Amagi Brilliant Park as it’s facing a possible shut down. Seiya, who was invited by Isuzu, is tasked to somehow save this failing amusement park. Though as Seiya is about to learn, this place isn’t run by people but fairies.

Busty girls, uniforms and plenty of mascots…yup sounds like an ecchi work. Amagi Brilliant Park by Gatoh Shoji is one part comedy and fantasy all with plenty of fan service thanks to Nakajima Yuka who handles the art. Amagi Brilliant Park is a lot of ecchi, but you won’t get tired of it as there is a great story behind Amagi Brilliant Park. While the light novel series is still going, you should check it out for some truly great ecchi. Amagi Brilliant Park is a great entry we feel in our Top 10 Ecchi Light Novel List so why not give it a try?

It should be another ordinary morning for Nanjou Shinobu that is until he realizes he’s not alone in his bed. Lying next to him is a cute and quite naked girl! Like most normal young men, Shinobu asks the question most would think to ask…why? Who is this girl and why is she here? Find out in the exciting ecchi story Tsuki Tsuki!

We could make a joke that maybe Shinobu was partying too hard but we won’t. Tsuki Tsuki from author Gotou Yuujin and illustrator Korie Riko is comedy and ecchi ramped to full volume. From the first volume, you’ll notice the usual themes of ecchi glory but Gotou throws in some interesting twists to make this not your typical harem ecchi story. Tsuki Tsuki is a unique story to be sure and you’ll want to dive into this odd supernatural work. Did we mention, loads of cute girls? Yeah, get going and read Tsuki Tsuki now.

Twenty three year old Yamano Masaru might be a NEET but he knows he needs some work. Luckily it seems Yamano gets a good job for testing what seems like a fantasy game. The pay is 250,000 yen and it seems the most he will have to do is live on site. However, little does Yamano know that his new job is not in this world but in a completely different one! What’s worse is Yamano learns that he must survive in this world and save it because it will die in 20 years!

Remember the old saying, sometimes it’s too good to be true? Maybe Yamano should have realized that in Neet dakedo Hello Work ni Ittara Isekai ni Tsuretekareta when he took his job. Though luckily for us, he didn’t cause then we wouldn’t get to enjoy such a great light novel. Neet dakedo Hello Work ni Ittara Isekai ni Tsuretekareta encorporates many genres into its narrative but that doesn’t mean it doesn’t work and in fact is awesome because of it. We applaud author Kasuga Katsura and artist Koban Sameda, this is a great light novel to read and you need to check it out people.

Eleanor Vertalia—or just Ellen—is a warrior for the Zhected as one of seven Vandais. The seven Vandais are known for being powerful thanks to weapons granted by a dragon. Each of the Vanadis must control seven territories but they are known to be the strongest warriors of the land so most don’t attempt to attack them. However, during a battle between Brune and Zhcted a man named Tigre finds himself defeated by Ellen. Now this young archer must work for Ellen what does his future hold going forth?

Madan no Ou to Vanadis might seem like a straight action story but don’t let the knight and medieval theme fool you. It doesn’t take long to notice just from the covers alone that the story will have plenty of cute girls and reasons for odd slip ups and awkward moments. At 16 volumes and counting, Madan no Ou to Vanadis seems to not be losing steam in the slightest. Great art, a fun adventure ecchi and a list of interesting moments make this light novel series a must for fans of the ecchi world. If you want, there is also an anime too that you can enjoy if you finish the light novel series and need more ecchi in your life.

In the world there exists legendary beings known as the Campione. These beings are second to no fighter and are able to rule over different powers and elements. Then one day when Kusanagi Godou kills a god-like being, he becomes one of these Campions. Once he wished to be a baseball player, now Kusanagi has the dream of defeating those who take the god-like powers they have and use them for bad. Alongside him are those who are his fearless followers, who just so happen to be beautiful girls as well.

Not only is Kusanagi a god like being but he’s got a bunch of girls following him? What’s so bad about this predicament? In Campione, the ecchi isn’t hard to spot and that’s thanks to Taketsuki Jou and Sikorsky who do an epic job making this ecchi light novel a blast to read. Not only does it have incredible fights but the several girls in this story all are cute and have some great concepts to bring to this tale. Don’t miss out on reading this amazing ecchi light novel series folks.

Thanks to Humanity, Earth has finally become uninhabitable to all life. Seeking to keep from going extinct, the remainder of humanity looked towards the sky for a place to live. Humanity would get their wish and find a new home on Tenjo, a world in the sky, but humanity didn’t learn from their folly and war once again breaks out. As their new home in the sky goes to waste, humanity’s various factions find one last spot on Earth that is still habitable. However, with so little in terms of available area, new measures will have to be taken to ensure that lives can be saved.

Kyoukaisenjou no Horizon may sound serious in nature but trust us people, it has plenty of ecchi and comedy balancing out this sci-fi action light novel. Following young Aoi Toori, he’s about to meet plenty of ladies as he tries to save the Earth. As per usual with ecchi works, Aoi will find himself in accidental situations and awkward moments abound in Kyoukaisenjou no Horizon. Thankfully Satoyasu—the illustrator—really does a fabulous job with artwork that shows the girls more prominent sides. Kyoukaisenjou no Horizon really does a great job making sure that yes your mind may wander into perverted thoughts but Kawakami Minoru won’t let you forget that this work is action as well.

120 years ago, Vice Admiral Lezirth Dawnbringer, saved the human race from the alien race Letix. Now however, he finds himself re awoken out of cold sleep and forced to rejoin the Navy but the world isn’t what he pictured. Being treated poorly, Lezirth is being sent with another human who was asleep to a new post to fight alongside a half-Elcro girl. What new battle will Lezirth and allies end up in next? Even more importantly, can he handle so many girls around him?!

We knew some of you mecha fans would be annoyed if we didn’t include mechs in our ecchi list. That’s okay Honey’s Anime has always got your back with recommending Dawnbringer: The Story of the Machine God. This amalgamation of genres works incredibly well thanks to author Hong Jung Hoon who makes a wonderful story not seen too often in mecha works. While still currently working we can’t say we know how the series will end unfortunately but we can say that so far it’s a very intriguing read and that’s coming from the mouths of other fans who have dabbled in this tale. Dawnbringer: The Story of the Machine God takes our third spot and it deserves it for being such a great read so far.

Poor 34 year old NEET seems to be having it rough. Not only was he kicked out of his home, he has been killed after saving a teenager. Luckily though the powers at be bless this NEET with a new life in a new world. Now going by the name Rudeus Greyrat, this once NEET is actually able to live a fulfilling life thanks to being blessed with strong magic. Rudeus is about to show the world what he is capable of doing in Mushoku Tensei: Isekai Ittara Honki Dasu.

Magic seems to be mixed with ecchi stories pretty well that’s one thing you can learn from a story like Mushoku Tensei: Isekai Ittara Honki Dasu. However, as with our list so far, ecchi may be an important to be qualified on our Top 10 Ecchi Light Novels listing but there has to be more to it. Mushoku Tensei: Isekai Ittara Honki Dasu delivers with cool magical battles, a fun story, and some amazing art thanks to author and illustrator Rifujin na Magonote and Sirokata. The ecchi light novel community holds this series in high regard and so do we after reading it. You won’t want to miss reading Mushoku Tensei: Isekai Ittara Honki Dasu.

Akatsuki Osawa is regarded as a hero, though maybe his other nickname “the rogue hero” is more fitting. After having just defeated the demon king, Akatsuki takes the demon king’s daughter with him back to his own world. Myuu is at first confused as to why he would do this but in time she understand that this was her father’s last wish. Now going to Akatsuki’s school for warriors in training, it seems she is about to discover a new life. However, can Myuu focus on school with perverted Akatsuki making her life a bit harder?

Our lists ends on Hagure Yuusha no Kichiku Bigaku and we saved the most ecchi for last. Cute girls, a busty main female lead and a perverted hero just is the ultimate staple of an ecchi work. USEU Tetsuto really knows how to keep a story comedic at times, ecchi at other moments and all around amazing to behold. Unfortunately, we do wonder about the series concluding as it has been on hiatus for some time but we keep our fingers crossed it will return. Until then if you do finish the light novel series we do recommend checking out the anime for even more ecchi harem goodness; just to be honest the light novel does it better.
