1. Amagami SS

Amagami SS provides a more relatable and realistic protagonist for harem stories. It’s about Junichi Tachibana, who has been suffering from social anxiety for the past few years after being held up on a date. Nonetheless, his romantic fortunes improve when several women show renewed interest in him.

To add to Junichiro’s dilemma, they are all intriguing anime high school girl stereotypes. Amagami SS is a relatively wholesome take on the frequently mature harem genre, and the anime generally avoids fan service.

2. Ouran High School

Ouran High School Host Club is an uncommon example of a reverse harem, in which the non-binary Haruhi is surrounded by a group of cute boys who make up the Ouran Academy Host Club. After shattering a costly vase, she enters the Host Club to pay off her debt to them.

Haruhi can easily pass as a boy or a girl, and she soon becomes a favorite among the clients of the flirtatious male hosts. Despite attracting many devoted clients, the males in the Host Club are also attracted to her. Ouran High School Host Club is one of the most iconic and beloved harems ever because it is not afraid to take its time and let its relationships develop organically, despite its occasionally wild nature.

3. Saber Marionette J

Saber Marionette J is a childhood classic for a significant number of millennials. This harem anime incorporates a variety of other genres, from mecha to comedy.

5. How Not To Summon A Demon Lord

How Not to Summon a Demon Lord is about an introverted gamer who isekai into his game. However, instead of being a regular guy, he adopts the role of Diablo, his in-game avatar. Indeed, as soon as he enters his new realm, he inadvertently enslaves the two girls who summoned him.

However, despite being incredibly powerful, Diablo agrees to assist these girls in breaking their contract, though the voyage there may be more difficult than anticipated. This anime is a little crazier and more romantic than Overlord, so anyone who has seen it may be familiar with it.

7. Tenchi Muyo! GXP

Fans of the original Tenchi Muyo may question why the show spends so little time in space, given that nearly every character possesses a spaceship. Tenchi Muyo GXP successfully incorporates a space opera into the original’s harem formula. Tenchi Muyo GXP’s main protagonist is Seina Yamada, a young man with the worst imaginable luck. When his parents believe they can get rid of him by giving him a job, they enroll him promptly.

Seina is now a member of the Galactic Police, patrolling deep space, to everyone’s astonishment. Tenchi Muyo GXP features an all-new cast in the same timeline as Tenchi Muyo Ryo-Ohki.

Those who enjoy the harem series with a touch of lore will want to check out this one.

Katarina, unwilling to be exiled or worse, seeks a happy ending. However, everyone in the game falls in love with her, both men and women. Katarina is a master strategist but lacks the intelligence to comprehend how she has become the object of everyone’s devotion.

9. Lord Marksman And Vanadis

Lord Marksman And Vanadis are among the few harem fantasy anime with a relatively severe tone. The plot centers around an ongoing territorial conflict in a fictionalized version of Europe; as a result, there are numerous political undertones and subplots in the series.

This conflict revolves around the unfortunate Tigrevurmud. He is one of the archers of an opposing faction whose army was decimated by Elen or Eleonora. Tigre’s turbulent struggle as a defector/prisoner of war for a female general begins when Elen spares his life in a strange twist of destiny.

---

12. Is This A Zombie?

Is This a Zombie? Tackles a peculiar premise. The primary character, Ayumu Aikawa, is a 16-year-old boy who dies at the beginning of the anime (yes, this is typical), but he transforms into a zombie.

Because Eucliwood Hellscythe revives Ayumu, she is instantaneously established as a prime waifu candidate. She is a necromancer, but she grants Ayumu the opportunity to pursue his murderer. As fate would have it, the protagonist encounters the remainder of his harem while attempting to resolve his dilemma.

13. A Couple Of Cuckoos

A Couple of Cuckoos contains a moderate amount of fan service, which may be positive or negative depending on the observer. Also, in a surprising deviation from most shows in the genre, the anime’s main male protagonist earns his harem. That would be Nagi Umino, the straight-A student. He intended to be wealthy but was mistakenly switched to another infant at birth.

When he turned 16, he met his actual parents and the girl whose life he had mistakenly adopted at birth. His adoptive and biological parents now want him to marry the girl. Other complications arise when Nagi pursues another person he genuinely values, and his adopted sister is also interested in him.

15. Oresuki: Are You The Only One Who Loves Me?

Oresuki begins with a high school student named Jouro, who initially seems frustratingly average and friendly. Underneath, he is a schemer who intends to gain the affection of either of his crushes through a bizarre but straightforward love triangle involving his best friend.

When everything seems to be going well for Jouro, a sharp-witted girl enters the conflict. She immediately recognizes Jouro’s deception, complicating his plans and relationships with his two intended targets and closest friend.

---

16. The Eden Of Grisaia

The Eden of Grisaia takes up precisely where its predecessor, The Fruit of Grisaia, left off, with Kazami Yuuji detained on suspicion of being a terrorist and unfairly sent to Mihama Academy as one of its six students. Thankfully, the ladies of Mihama Academy will not allow Kazami to be used for political purposes.

The Eden of Grisaia, like its antecedent, is more serious than most harem anime. Rather than relying primarily on humor and romantic drama, this series takes a psychological approach to its story, distinct from the rest of the humorous subgenre.

---

17. Saekano: How To Raise A Boring Girlfriend

Saekano: How to Raise a Boring Girlfriend has multiple seasons; each new installment is greater than the last. In this series, fans follow Tomoya Aki, an anime and light novel fanatic who develops his own game. In his efforts to assemble a team, he encounters the lovely and composed Megumi Katou.

Tomoya ultimately decides to base his protagonist on Megumi, and they embark on a semi-romantic journey together. At first glimpse, Saekano does not appear remarkable. Fans agree that it is undoubtedly one of the best modern harem series available. It has everything harem fans adore, from its original plot to its well-developed cast of characters.

18. We Never Learn: Bokuben

In We Never Learn, a needy student named Yuiga is offered a full scholarship to attend a prestigious university. He must tutor the school’s geniuses in their weakest disciplines, however.
