While many popular harem anime get widespread attention, there remain quite a few lesser-known gems in the genre that deserve more love. These are called the most underrated harem anime that possess the potential, yet a handful of people either know them or rate them below the deserving.
You can assume harem as a subgenre of romance often used to attract male audiences. The harem anime explores the dynamics between one male lead and multiple charming female characters vying for his affection. Though sometimes overlooked, these shows cleverly incorporate drama, comedy, and heartwarming moments that keep viewers engaged from start to finish.

10: The Legendary Hero Is Dead
Let’s start our list with the most hilarious anime on this list, “The Legendary Hero Is Dead.” Some may refer to it as a “guilty” pleasure anime, but for fan service enthusiasts, there is nothing “guilty” about it.
Unlike most harem anime, this show depicts the super lousy protagonist, “Touka Scott.” He was living his life as a commoner pervert until the legendary Hero Sion was caught in his set trap by accident and met his demise.
A loli necromancer witnessed the incident and swapped Touka’s soul for Sion’s body as a punishment for slaying the renowned hero. As a faux hero, Touka must complete hero responsibilities while also building his harem throughout the tale.
9: Oreshura
Oreshura is your standard romantic comedy/harem, having a lighthearted tone. It revolves around the conflict between the protagonist’s crafty “girlfriend” and his boyhood friend’s jealousy of him.
Despite being produced by a well-known studio, “A‑1 Pictures,” this show has gone underappreciated because it failed to deliver what it never promised in the first place.
The show features the dull person Eita Kidou, who lives for one reason only: to study. Here appears the school’s most coveted girl, who also has no interest in love and asks Eita to pose as his boyfriend to escape unwanted attention.
He initially refuses, but he eventually agrees after she starts blackmailing him. Eita’s life has been flipped upside down by a phony romance with the most sought-after girl at school.
8: Tsugumomo
These days, very few anime truly have titles that correspond to the show’s subject matter; in this instance, Tsugumomo is most likely the first one I have actually encountered.
The story follows the life of Kazuya Kagami, a normal high school student, who one day is confronted with the fact that the obi that he had inherited from his mother had transformed into a beautiful chick and protected him from danger.
Now with this new hot chick under his wing, how is he going to navigate through this dull life? It’s your task to know by witnessing this one of the most underrated harem anime, which actually deserves more.
7: A Couple of Cuckoos
If you’re the type of watcher who simply wants to see some great people grow and develop, and doesn’t care about reviews; give this underrated romance gem a shot and you won’t be disappointed.
Nagi Umino and Erika Amano, both with distinct personalities, discover that they were exchanged at birth. With this surprising news, both families propose their engagement to Radeem in this unfair situation.
Even though the couple didn’t want this, both families were not willing to back down. What is going to happen with their relationship? Only time will tell.
6: Classroom For Heroes
The only way to admire this generic anime is to just turn off your brain and begin watching this anime. Classroom For Heroes is not your epic shonen but merely a generic harem show that solely exists for comedy and fanservice.
Following a similar plot setting to Frieren Beyond Journey’s End, the MC of this show has defeated the Demon King and nearly lost most of his strength.
Now he’s free from the obligation of human savior. He enrolls in an academy as a student to live a tension-free life, helping amateurs become heroes. Throughout the series, he helps many friends, “mostly females,” building his harem.
5: Beast Tamer
In terms of plot, Beast Tamer is an exact clone of the popular isekai anime “Rising of the Shield Hero,” although it goes more smoothly while forming a harem and has an easy-to-follow plotline.
The show stars Rein, the ultimate wholesome protagonist, who is humiliated by the hero party for being weak and ineffective.
His determination to be a hero paid off when he entered into a contract with Kanade, a cat spirit. With this pact, Rein is overpowered, but his fate will bring him more extraordinary spirits throughout the storyline.
4: World’s End Harem
What is your initial thought when you witness a show like this? “Oh god, what a trash.” Let me tell you, it was the same for me until I watched it. Because this program is capable of greatness with such an extreme ecchi harem plot.
The protagonist of this series has been in hibernation for research purposes, while in the process, humanity has been plagued by a dreadful virus that only kills the male species.
On awakening, he finds out he is one of the few males on the whole Earth, and now every woman on the entire planet is desperate to mate with him.
Even with this absurd plot, World’s End Harem stands out as one of the most underrated harem anime shows.
3: Tenchi Muyo! War on Geminar
Despite having enough action sequences, slick animations, and binge-worthy character growth, Tenchi Muyo! War on Geminar was overlooked simply because it was an original series.
Kenshi Masaki has been kidnapped to another globe on a mission of assassination. Even so, he failed to do so and was apprehended alive. His life is spared solely because he is male, which is extremely uncommon in Geminar.
He is hired as the personal assistant to the girl he intended to kill. With his entry into this dominion, the new evil forces awoke and wreaked havoc on Gemini. Will he be able to eliminate this threat?
2: Aesthetica Of A Rogue Hero
Have you grown tired of wimpy protagonists who are always hesitant to act? Have you grown tired of the ridiculous power-ups and “power of friendship” crap? If the answer is yes, this anime is ideal for you.
Since the discovery of unique portals, young humans can travel through dimensions and return with tremendous powers.
Among them is Akatsuki Ousawa who has defeated the demon king of the other world and returned along with the daughter of that demon king.
As he returns, he mandatorily has to join a unique school for special powers possessors, and he can’t reveal the identity of the demon king’s daughter. How will he cope with this situation while building his own harem, which is quite fast-paced?
1: Danmachi
Danmachi is one of the renowned fantasy action anime series that also presents the world’s most natural harem building while maintaining the plot as binge-worthy shonen.
Follow the cute little Bell Cranel, a newbie adventurer who lives the dream of becoming a professional adventurer.
