New Harem Anime 2025

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 has been quite good.

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 us go through all the ones announced so far, including series that have aired and ones that have yet to debut.

Updated on June 23, 2025 by Mark Sammut: The Spring 2025 season is nearly done, so now it is time to focus on the upcoming Summer 2025. The lineup has plenty of harem content.

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 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

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!

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

Solo Leveling, Sakamoto Days, and Apothecary Diaries aired as part of Winter 2025’s anime lineup, and some series were 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

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 is a fairly typical example of this concept, albeit with a more pronounced harem than most of its contemporaries. Zenos is an extremely talented healer who starts an underground clinic, and he pretty quickly attracts a group of female clients. Now, to his credit, Zenos is a fairly proactive and direct protagonist for this type of story, so he is not a bad harem lead.

I’m the Evil Lord of an Intergalactic Empire!

Another isekai harem, I’m the Evil Lord of an Intergalactic Empire! also throws mecha into the mix, which has made for a messy but fun 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.

16 Best Isekai Mecha Anime & Manga

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 a position of power, granting him the perfect opportunity to be the worst.

I’m the Evil Lord of an Intergalactic Empire! is not for everyone, as it does kind of require an appreciation for three polarizing genres. Focusing only on the harem element, the anime’s main girls have cute designs and have defined roles within Liam’s empire. That said, Amagi has gotten way more attention than any of the other girls, and she is the only one that comes across as a main character.

The Gorilla God’s Go-To Girl

Set in a fantasy world where people are awarded blessings by the 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.

Sophia quickly finds herself surrounded by guys, although that does not mean they will all go down the romance route. The Gorilla God’s Go-To Girl just about qualifies as a reverse harem since, well, the female protagonist is surrounded primarily by guys, most of whom could easily transition into love interests. That said, the anime presents Louis as Sophia’s main romantic partner.

The Unaware Atelier Meister

The Unaware Atelier Meister is a weird one. On paper, this fantasy anime has all the ingredients to be a conventional harem. The male lead, Kurt, is considered to be super adorable and seems to naturally attract girls to him, most of whom seem to be both enamored and puzzled by his wholesomeness. While not the only noteworthy guy in the cast, the MC spends most of his time with female characters, developing fun friendships with most of them.

However, Kurt does not have a single romantic bone in him. He is about as “innocent” as they come. His naivety is treated as a concern by the rest of the main characters and, I admit, can become annoying at times. The Unaware Atelier Meister is a platonic harem, if that makes sense.

Summer Pockets

It has been too long since a visual novel by Key received a fantastic anime, but Summer Pockets has the potential to set things right. The 2018 game has routes for multiple girls (four in the base version, eight in the Reflection Blue expansion), making it a fairly conventional harem by visual novel standards. Due to being in its early days, the adaptation’s direction is not 100% obvious at this point, but it will likely cover all four routes to an extent, even if it might not emphasize romance as much as some other 2025 harem anime.

Best Visual Novels For Beginners, Ranked

For gamers who are curious about dipping their toes into the ever-growing visual novel genre, these games make for the perfect introduction.

Looking to leave behind city life and rediscover himself, Hairi heads to a small island called Torishirojima for a summer holiday. Once there, he quickly starts running into the local teenagers, who are primarily (but not exclusively) female. He takes a particular interest in the mysterious Shiroha, although she is not the only girl who walks into his life. Summer Pockets is very much a typical visual novel adaptation that tries to cover as many routes as possible, which tends to result in a fairly slow story that cycles through different girls.

The Shiunji Family Children

From the same mangaka behind Rent-a-Girlfriend, The Shiunji Family Children is considerably less popular than its bigger sibling. Still, this 2025 harem anime is a more traditional 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.

The Shiunji Family Children is a fairly well-done but mostly unspectacular harem story that plays things surprisingly safely considering its premise. Doga Kobo has brought its typical polished presentation, delivering quality animation that will likely rank among the harem genre’s best efforts of the year. The story is OK for what it is.

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.

Best Romance Anime To Watch If You Love Rent-A-Girlfriend

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.

Watari-kun’s ****** Is About to Collapse

I have to admit, Watari-kun’s ****** Is About to Collapse is a pretty great and eye-catching title. Like, what does it mean? Well, that is a mystery. Naoto is obsessed with protecting his sister, but his life becomes complicated when a strange girl shows up who claims to hold secrets relating to the male protagonist. What does she know? What does she mean?

Just to keep expectations in check, while the manga incorporates some psychological elements, it is primarily a romantic-comedy rather than a thriller. I enjoy these types of stories, but the title does, admittedly, paint a somewhat different picture.

The Shy Hero and the Assassin Princesses

OK, this one has my attention. The Shy Hero and the Assassin Princesses pairs a powerful hero with three female party members, a situation that delights Toto as he has always struggled to connect with people. Unbeknownst to him, his companions are actively trying to kill him, and they are all quite deadly in their own right.

So, yes, The Shy Hero and the Assassin Princesses should be a deadly harem, a concept that is rarely explored in anime. Now, the series probably will not be that dark, as the manga is fairly lighthearted.

Private Tutor to the Duke’s Daughter

Fantasy setting aside, Private Tutor to the Duke’s Daughter has a conventional set-up for a harem. Allen, a capable but underachieving sorcerer, is hired to tutor the duke’s daughter, Tina, in magic. They do not quite get along at first, but things develop naturally after that point. While Tina is introduced as the main girl, Private Tutor to the Duke’s Daughter should expand into a harem quite quickly, with Allen helping a series of girls who, in return, show romantic interest in him.

The light novel and manga are not extremely highly regarded, but they are fine enough for what they are trying to be. Private Tutor to the Duke’s Daughter will likely be a fairly safe and traditional fantasy harem, which can be fun when a viewer is in the mood for fluff.

A Couple of Cuckoos 2nd Season

A polarizing anime (and manga), A Couple of Cuckoos will test a viewer’s patience at times. 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.

Dealing with Mikadono Sisters Is a Breeze

Dealing with Mikadono Sisters Is a Breeze, aka 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. Assuming the adaptation goes, this upcoming harem anime could be among the year’s better efforts.

Nukitashi the Animation

• ​​​​​Start Date: July 2025
• Studio: Passione
• Based On: Visual Novel

Passione has such a weird resume. The studio has worked on Ishura, Spice and Wolf: Merchant Meets the Wise Wolf, Mieruko-chan, Higurashi, and Wasteful Days of High School Girls, all good and relatively mainstream shows; however, Passione also loves a bit of debauchery. Chained Soldier, Interspecies Reviewers, and Harem in the Labyrinth of Another World are very much ecchi anime that cross the line into full-blown 18+ territory, particularly the latter two. Nukitashi the Animation seems set to follow in their footsteps.

My Dress-Up Darling, Dandadan, Kaiju No, 8, and Sakamoto Days are part of the Summer 2025 anime lineup, and here is where you can watch them.

Fall 2025

Chitose Is in the Ramune Bottle

More of a slice of life option, Chitose Is in the Ramune Bottle should be worth checking out for those craving protagonists who are more confident and self-assured than the traditional harem lead. While not flawless, 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.

Don’t Touch Kotesashi

One of the more surprising harems to receive an adaptation, Don’t Touch Kotesashi will likely lean completely into fanservice territory, at least if it sticks true to the source material. The eponymous Kotesashi is a talented massage therapist who has fallen on hard times, so he accepts a position at a dormitory. Besides other responsibilities, one of his main roles is to massage sports athletes, who are naturally girls.

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.
