Harem anime is an acquired taste, even more so than genres like isekai and sports. Often looked down upon for catering to basic wish fulfillment, these shows are rarely regarded as high art; however, they are popular and can be very entertaining, serving as lighthearted escapes from reality. New harem anime are always coming out, and 2025’s lineup is shaping up to be quite exciting.

Throughout the year’s four seasons, the industry will produce plenty of new series and sequels to well-established shows. While perhaps not attracting the same attention as some other stories, these 2025 harem anime could prove to be highlights in their own right. Let’s go through all the ones announced so far.

Updated on March 26, 2025 by Mark Sammut: The Spring 2025 anime season is about to start, and the lineup has a few harem shows that should keep fans of the genre entertained.

Winter 2025

I’m Getting Married to a Girl I Hate in My Class

I’m Getting Married to a Girl I Hate in My Class should not qualify for a harem. After all, the premise involves Saito, the male lead, marrying his classmate, Akane. They are the core relationship and the obvious endgame, and any other love interests would be largely pointless. Yet, I’m Getting Married to a Girl I Hate in My Class is oddly structured similar to a comedy harem, in the mold of something like Rent-a-Girlfriend.

Best Openings Of The Winter 2025 Anime Season, Ranked

The winter 2025 anime season featured some truly remarkable openings for viewers to enjoy, but these are arguably the best of the bunch.

Saito and Akane’s strained relationship takes center stage, but the former is also courted by Himari, the protagonists’ classmate. She is not aware of their situation, and she pursues Saito quite aggressively. Furthermore, Shisei constantly makes aggressive attempts to get with her cousin, Saito. These moments are played for laughs, both by the show and the characters, but they create a scenario where the MC is effectively being pursued by three girls.

Beheneko: The Elf-Girl’s Cat is Secretly an S-Ranked Monster!

• Japanese Title: S-Rank Monster no “Behemoth” dakedo, Neko to Machigawarete Elf Musume no Pet toshite Kurashitemasu
• Studios: Zero-G, Saber Works
• Based On: Light Novel by Nozomi Ginyoku
• Streaming Service: HIDIVE

Comfortably the most risqué harem anime of Winter 2025, Beheneko revolves around a cat protagonist and the various fantasy-themed girls who love him. Yeah, that description will likely be enough to determine whether someone will want to check out Beheneko or not. It should be said that the series spends quite a bit of time showing the characters on quests and adventuring.

Possibly the Greatest Alchemist of All Time

Possibly the Greatest Alchemist of All Time

Release Date

January 1, 2025

Possibly the Greatest Alchemist of All Time is a weird one. The anime has a fairly stereotypical set-up for a harem, with the male protagonist surrounding himself with female characters who quickly start to worship the ground he walks on. They are also “employed” by him, as he bought their contracts. The isekai MC, Takumi, does not hide the fact that he is attracted to two of the girls, Sofia and Maria; conversely, the girls are completely dedicated to him, with Maria saying she will spend the rest of her life with Takumi.

Yet, the show has zero romantic tension. Part of that is due to Takumi, who just refuses to be direct and, instead, just makes comments from a distance. This creates a bizarre dynamic that resembles a harem but lacks any of the genre’s fun parts.

The Daily Life of a Middle-Aged Online Shopper in Another World

The Daily Life of a Middle-Aged Online Shopper in Another World

Release Date

January 9, 2025

Not every isekai anime is a harem, but the themes overlap enough that they are still synonymous with each other. The Daily Life of a Middle-Aged Online Shopper in Another World follows Kenichi, a guy who finds himself in another world with the ability to shop online.

Every New Isekai Anime Announced For 2025 (So Far)

Isekai anime is inescapable, with each season containing a couple of shows. Here are the 2025 isekai anime series announced so far.

That power is reminiscent of Campfire Cooking in Another World with My Absurd Skill, which was legitimately one of the best isekai anime of 2023. However, this Winter 2025 series is a full-blown harem, with Kenichi utilizing his unique ability to set up a comfortable life for himself. Somewhat refreshingly, the protagonist does not waste any time building up a harem, despite not specifically trying to go in that direction. Women just seem to be naturally attracted to him, and their relationships are quite casual.

Anyway, I’m Falling in Love with You

Harem anime are rare next to genres like isekai, but they are frankly abundant when compared to their reverse variants. Nowadays, most years seem to produce two or three shows that shake things up by dropping a female protagonist in the middle of a gaggle of guys, and this shortage is not surprising considering shojo adaptations are hard to come by. Still, they do exist, and Anyway, I’m Falling in Love with You is a fairly conventional example of a reverse harem.

Not sure how to react to a confession from a childhood friend, Mizuho struggles to accept that the relationships that have been a staple of her life might be set to change. Compared to most harems that tend to revolve around strangers, Anyway, I’m Falling in Love with You focuses on characters who already have bonds, exploring how the introduction of a crush changes their relationships.

From Bureaucrat to Villainess: Dad’s Been Reincarnated!

TBS, MBS, CBC, Tulip Television, BSN, tys, NBC, HBC, RKK, i-Television, SBS, IBC, BSS, MRO, OBS, TUF, RSK, TUY, tbc, RKB, SBC, KUTV, RBC, UTY, RCC, MRT, atv, MBC

While not initially seeming like a harem, this Winter 2025 isekai anime goes in that direction, even if its exploration of the theme is primarily comedic. Kenzaburou, a middle-aged father, meets truck-kun and is reincarnated as Grace, the villainess of an otome game. Attending school alongside the heroine, Anna, the protagonist’s parental instincts tend to take over in most situations, resulting in Grace playing matchmaker. More often than not, the MC inadvertently triggers romance milestones with the Student Council members, who are presented as the main love interests; however, he is also an active participant at times, specifically when it comes to aiding Anna.

Besides its comedic tone and fantasy setting, From Bureaucrat to Villainess: Dad’s Been Reincarnated! sets itself apart from other shows by, technically, featuring two characters who are building harems. Kenzaburou’s actions are causing characters to fall for both Grace and Anna; in fact, the latter is also developing a thing for the former.

The 100 Girlfriends Who Really, Really, Really, Really, Really Love You Season 2

Arguably the most highly anticipated harem anime of 2025, 100 Girlfriends hit the ground running with a hilarious opening season that managed to parry the genre while still delivering a surprisingly effective romance. Due to a god-level mistake, Rentarou has 100 soulmates, and he has to make them all happy or their lives will go to ruin. So, he does just that, proving himself to be the ultimate harem protagonist.

Best Winter 2025 Anime, Ranked (So Far)

Solo Leveling, Sakamoto Days, and Apothecary Diaries are airing as part of Winter 2025’s anime lineup, and some series are better than others.

100 Girlfriends is primarily known for its comedy, but it works well as a harem. The characters are likable, with the girls showing enough personality to not just be basic archetypes. Season 2 instantly eclipsed its predecessor’s silliness by having the girls switch bodies within the first few minutes, a short-lived plot development that provided laughs and kisses in equal measure. New girls are gradually introduced, with usually a candidate appearing every two episodes or so. Despite its ever-expanding roster of waifus, 100 Girlfriends does a surprisingly great job of fleshing out most of them, rather than just reducing them to one gag. While still too early to say, 100 Girlfriends season 2 will likely be among the best harem anime of 2025.

Spring 2025

The Brilliant Healer’s New Life in the Shadows

The Brilliant Healer’s New Life in the Shadows

Release Date

April 3, 2025

Over the last two years or so, a strange fantasy subgenre has taken hold: Kicked out of a party. In all these shows, the protagonist is abused and mocked by his party, eventually resulting in him being kicked out and left to rot. However, in reality, the MC is not only super strong but also the main reason the party had any success. Naturally, the protagonist winds up proving everyone wrong, all the while attracting a plethora of girls who see him as his true self.

The Brilliant Healer’s New Life in the Shadows seems set to be a fairly typical example of this concept, albeit with a potentially more pronounced harem than most of its contemporaries. Zenos, the protagonist, is an extremely talented healer who starts an underground clinic.

I’m the Evil Lord of an Intergalactic Empire!

I’m the Evil Lord of an Intergalactic Empire!

Release Date

April 5, 2025

Another isekai harem, I’m the Evil Lord of an Intergalactic Empire! also throws mecha into the mix, which should make for a fun and chaotic series. A hard-done-by protagonist dies after living just the most miserable life imaginable, and he is granted an opportunity to cut loose in a new world.

These anime and manga feature a perfect mix of the escapism of isekai storylines and the futurism of mecha narratives.

The “Guide” who offers this second chance is also the one who ruined the MC’s previous life, and they seem interested in pushing a “good” person to be evil. Living as Liam, the protagonist is specifically born into an evil empire’s family, granting him the perfect opportunity to be the worst. However, it goes against his nature.

The Gorilla God’s Go-To Girl

The Gorilla God’s Go-To Girl

Release Date

April 6, 2025

This one is not guaranteed to be a reverse harem, but the main visual, trailer, and premise certainly point in that direction. That said, they also suggest The Gorilla God’s Go-To Girl might be among Spring 2025’s funniest anime. Set in a fantasy world where people are awarded blessings from gods, Sophia’s peaceful future is snatched away from her when she earns super strength, courtesy of a gorilla deity.

Due to this rare and powerful ability, Sophia is, naturally, scouted by the Royal Knights, forcing her into a life of hard training and combat. Going by what has been revealed, Sophia will be surrounded by seven guys, although that does not mean they will all go down the romance route.

The Shiunji Family Children

The Shiunji Family Children

Release Date

April 8, 2025

From the same mangaka behind Rent-a-Girlfriend, The Shiunji Family Children is considerably less popular than its bigger sibling. Still, this upcoming harem anime could be a more well-rounded and typical entry in the genre, potentially making for an easier but less interesting watch. Also, the harem revolves around a step-brother and his step-sisters. So, take that as you will.

Summer 2025

Rent-a-Girlfriend Season 4

Arguably the most polarizing harem anime of all time, Rent-a-Girlfriend has a fairly negative reputation, all the while being among the most recognizable and well-known representatives of the genre. Rent-a-Girlfriend is pretty unusual for a harem since the “final” girl has been obvious from the very start, with Kazuya very clearly preferring Chizuru above everyone else.

Rent-A-Girlfriend is a great romcom and there are a lot of awesome anime that are similar if you’re looking for something else in the same vein.

Season 3 was the anime’s best entry yet, largely thanks to a fun movie-based storyline that allowed the characters to shine. Season 4 will likely satisfy fans of Rent-a-Girlfriend, while offering nothing to those who hate it.

2025 Harem Anime With No Release Season

A Couple of Cuckoos 2nd Season

A polarizing anime (and manga) that will test a viewer’s patience at times, A Couple of Cuckoos is a bit of a weird one. When viewed as a silly comedy about mostly awful people, it is pretty entertaining, with the girls driving the male lead up the wall in frequently amusing ways.

6 Anime Protagonists Who Don’t Realize They Are In A Harem

The oblivious protagonist in a harem setting enriches the story with layers of comedy, character interaction, and ongoing suspense.

As a harem or, worse, a romance, the anime falls a bit flat. Nagi has to put up with a lot of nonsense from the rest of the cast, and none of them seem like particularly great fits. The harem aspect also moves at a glacial pace, especially since Erika is the obvious end goal.

Chitose Is in the Ramune Bottle

Seemingly more of a slice of life option, Chitose Is in the Ramune Bottle is worth checking out for those craving protagonists who are more confident and self-assured than the traditional harem lead. While not without flaws, Saku is a pretty popular guy who mostly knows what he wants and is good at interacting with girls; however, he is not always great at managing romantic feelings.

Chitose Is in the Ramune Bottle should be more about friendship than romance, at least initially. Along with Saku, the anime should feature five main girls, all of whom should receive attention.

The Three Mikadono Sisters Are Surprisingly Easy

The Three Mikadono Sisters Are Surprisingly Easy is a pretty great manga that benefits from having a fantastic male protagonist, or at least a refreshing one for the harem genre. The son of an accomplished actress, Yuu simply does not have his mother’s talent, nor the desire to be held to those standards by others. However, his goal is to find and nurture a happy family environment.

Yuu ends up living with three sisters who are all talented in different fields and dedicate all their energy to excelling in that area, at the expense of their relationships.

Other Anime That Could Have Harem Elements

100% full-blown harems are fairly rare, at least compared to other genres and themes like action, traditional romance, and isekai. However, die-hard fans craving more content can always check out a few other shows that either sprinkle in harem content or feature dynamics that would not be out of place for that genre. The following anime are not quite harems, but they might be enjoyed by viewers who want harems.
