The harem genre in anime has been available for decades, influencing a small patch of weebs worldwide until the iconic entry of High School DxD. High School DxD is a show that pushes the boundaries of the ecchi genre, attracting youth to witness the boldness of anime.
Stained with extreme fanservice and uncomfortable ecchi scenes, this show is still considered the godfather of the ecchi harem genre.
The way it blends full-action battles with comedic fan service is considerable art that no fan can resist; thus, most fans longed for anime like High School DxD. The list below is custom-tailored for those weebs, so let’s jump into it.

10: Prison School
Issei Hyoudou was a perverted main character of High School DxD, but in Prison School, the whole cast of main characters is perverted to the core. Though the graphics of this anime aren’t as bold as those of DxD, the dialogues are rotten enough to cope with it.
The story revolves around a bunch of perverted male students who get caught red-handed while peeping on girls. The all-female council of this school sentenced them to two months of school prison as punishment. However, this punishment turns out to be more rewarding, and you’ll know as you watch.
9: Demon King Daimao
Demon King Daimao presents an irresistible formula blending action-packed battles with ecchi scenes like no other. The best thing is that the scenes will never feel forcefully implemented.
The story features Akuto Sai, a boy who wants to become a priest, but destiny has a polar opposite path for him.
It’s revealed that he’s going to be the next Demon King. After this shocking revelation, a rollercoaster of wild battles begins where fearsome females are attracted to MC for just one reason: he’s strong.
8: The Trinity Seven
Trinity Seven is another standout pick for fans of High School DxD if you’re more into harem and humor. The story follows Arata Kasuga, whose world is destroyed as a result of the magical event, and now he enrolls in the magical academy, where he gets to join the student council, which is filled with seven alluring females.
Such a typical plot setting is expected from a harem, but how its clever writing and self-aware humor contribute to character development is the best thing. It’s less fan service-oriented than High School DxD but offers great world-building.
7: The Testament of New Sister Devil
If you’re looking for an anime that can beat even DxD for its unapologetic ecchi theme, it could only be The Testament of New Sister Devil. In DxD, the main character was a pervert; in this anime, the whole female cast is lusty.
The story revolves around Basara Tojo, a high school student whose life takes a sharp turn when his father suddenly remarries, leaving him with two new stepsisters, who turn out to be a demon princess and her succubus servant.
Now, Basara has to protect his family while establishing an unapologetic relationship with her step-siblings.
6: Harem in the Labyrinth of Another World
Harem in the Labyrinth of Another World is a darker, more mature take on the isekai and harem formula. To be honest, it’s only a mature take that is beyond the limit of fanservice, which can be disturbing.
Michio Kaga is your disillusioned teen who finds himself transported to a mysterious RPG-style world. In this world, he has just one task: navigate the dungeon to make a living. However, he has other milestones to achieve, like building his harem consisting of loyal servants. Caution alert: Only dare to watch it alone.
5: The Qwaser of Stigmata
The Qwaser of Stigmata stands out as one of the more controversial and provocative entries in the supernatural ecchi genre. Why it’s more controversial, please read its storyline ahead.
This bold anime features Alexander Nikolaevich Hell, a warrior who can manipulate elements using the power of Soma. Interesting, huh! But what is Soma? It’s mystical energy that can only be derived through breast milk. It’s way more extreme than you can think, so watch at your own risk.
4: High School of the Dead
The vibrant action and boob-jiggling battles are what make High School DxD more elite ecchi than others. However, High School of the Dead offers more ugliness if you’re not aware.
So, High School of the Dead, created by the great Madhouse Studios, features an intense atmosphere in which Japan has been overrun by zombies, and a group of high school students must now protect themselves from this disaster.
While navigating through this rampage, they go through intense battles and awkward moments that are difficult to explain. So make sure you don’t miss this masterpiece of ecchi.
3: Date A Live
Date A Live is what happens when you mix world-ending spirits, sci-fi tech, harem hijinks, and a whole lot of awkward flirting.
The premise of this anime is delightfully absurd. Humanity is plagued by mysterious spacequakes caused by powerful spirits, which are females, and the only way to stop them is not with weapons but with… dates.
Yes! And there is our protagonist, Shido Itsuka, who solves this disastrous problem by kissing these spirits gently.
2: Aesthetics of a Rogue Hero
Aesthetica of a Rogue Hero featured an overpowered main character who had defeated the other world’s demon king. Still, ladies fear him for another reason, which is that he can steal lingerie without making them realize it.
Fun things aside, if you’re an overpowered character lover who is flirtatious and walks through tough times like nothing, this anime serves.
1: Infinite Stratos
I can confidently say that Infinite Stratos is a cult cousin of High School DxD. Like its mecha theme, a little perverted and special protagonist, lots of cute girls, and a battle-torn world.
In a world where only women are able to pilot the powerful mechas known as Infinite Stratos, Ichika Orimura, a seemingly average teenage boy, becomes the first male ever to operate one.
This event thrusts him into the prestigious IS Academy, where he becomes the center of attention among the elite female students. Being the only guy in the school, Bro has to navigate lots of girls falling head over heels for him.
