In the age of Gen Z, an appropriate amount of fan service has become the most necessary ingredient in cooking up a great show. However, there are some shows that push the boundaries of this fanservice to a limit that it became a whole new genre, which is called Ecchi.
The blend of risqué moments along with the main plot of anime is what defines the greatness of an ecchi show, and today, we have curated the most updated list of such animes that redefine the boundaries of the ecchi genre.
So, if you’re all set to witness the saucier side of the Japanese anime industry, make sure to stick with us until the end.
10: Danmachi

Danmachi anime is the rarest example of a show that seamlessly blends the risqué moments while preserving the main plot. So, if you’re a guy who loves beautifully animated fights along with beautifully designed gals, Danmachi is perfect for you.
Danmachi is about a very optimistic character, Bell Cranel, who dreams of becoming the greatest adventurer in the land. Fatefully, he encounters a lonely goddess, Hestia, whose support becomes the first step for Bell to conquer this journey.
To be honest, it’s a show full of fantasy dungeons attracting such beautiful gals, giving us an Ecchi-rich experience.
9: Vermeil In Gold

Those who crave unrealistic figures of milfs are most welcome to the Vermeil in Gold, a show that is well-reputed for only one good reason: its main character Vermeil.
The show features Alto Goldfilled, a magic student who accidentally summons the most seductive demon in the universe, Vermeil. Upon being released from thousands of years of imprisonment, Vermeil becomes the familiar of Alto out of gratitude, sealing their contract with a deep, hot kiss.
From this little premise, I hope you will have gotten a glimpse of what this show has packed for you, so go ahead and find out in the lewdome journey of Vermeil and Alto Goldfilled.
8: Why the Hell are You Here, Teacher!?

If the amount and intensity of fan service are what define the greatness of an Ecchi show, then “Why the Hell Are You Here, Teacher!?” is arguably the peak of the Ecchi genre.
This anime is about a super lucky dude, Ichirou Satou, who always somehow got involved in an intimate encounter with his teacher Kana. The episodes are super short, featuring the most impossible interactions between teachers and students. If you’re imaginations are running wild with this little premise, this show is fully jacked for you.
7: Highschool of the Dead

Ever heard the name Mad House Studios? Yeah, it’s a well-reputed studio that has a great history of giving smooth animations to some renowned shows of history, like Hajime no Ippo and Death Note. And when a show with a saucy premise came into the hands of such a productive studio, a masterpiece like High School of the Dead came into being.
The premise is super simple. A virus runs wild in Japan, converting humans into zombies. Takashi Komuro, a calm and collected high schooler, takes the frontline to eliminate this threat while saving his ex and other high school gals. Those who want to witness wavy fluid animations should invest in this top-notch show.
6: The Testament of Sister New Devil

Imagine a script where you don’t care about the plot, you don’t care about what happens with side characters, you don’t even care about the villains, and all you care about is why and for what reason the females will fall for MC. It’s the whole script of The Testament of Sister New Devil.
Basara Toujou is a member of the Heroes clan who works to eliminate demons. One day his father introduced him to his stepsisters, who are revealed as the daughters of the demon lord. Now, what will Basara do? You can see for yourself, but just make sure to watch this alone.
5: Prison School

Brace yourself because I am introducing you to the most craved jail of the universe.
Prison School is a classic Ecchi anime where some naughty dudes are sentenced to jail for peeping on girls in the restroom. Now, they have to go through the harsh environment of this jail for two months while dancing at the fingertips of some of the most wicked jailers.
4: My First Girlfriend Is a Gal

Imagine your best buddies propose to the school’s hottest gal on behalf of you as a mockery, and your proposal gets accepted out of the blue.
This is the whole story of My First Girlfriend is a Gal, where the MC Junichi Hashiba, a low-self-esteem high schooler, becomes the bf of the school’s hottie. This anime is a journey showcasing how this perverted yet low-confident lad gets rid of his sexual desires while dating a gal.
3: No Game No Life

No Game, No Life is a gem of the ecchi genre, which presents the best blend of comedy and verbal fan service to the table. From beginning to end, your jaw will remain wide open, and you’ll witness this on your own.
No Game, No Life is what happens when two genius shut-ins decide the real world is too boring and conquer a fantasy realm instead. Between Shiro’s “totally necessary” bath scenes, Steph’s endless humiliation, and Jibril’s, ahem, questionable curiosity, this show knows exactly what it’s doing.
2: Jobless Reincarnation

Jobless Reincarnation takes the classic isekai formula, adds a touch of adventure, and cranks the ecchi dial-up just enough to keep things interesting. I bet if you’re a slow-paced story lover, this is the perfect show to watch at the end of the day.
Reborn as Rudeus Greyrat, a once-loser now gifted with insane magical talent (and very questionable thoughts), he embarks on an epic journey of growth, redemption, and… well, ecchi moments that definitely push boundaries.
1: High School DXD

High School DXD is the cult classic of the ecchi genre, which to this date is unarguably the best ecchi anime of all time. Why is it the best Ecchi? I bet you won’t witness a single episode without peak fan service.
Issei Hyoudou starts as your average pervy high schooler, but after getting resurrected by the ridiculously gorgeous Rias Gremory, he finds himself in a world of supernatural battles and some very risque moments. It pushes the boundaries of fanservice to such a level that I can’t even describe, so make sure you don’t miss it.
Most of the anime on this list are available on Crunchyroll.
