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 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 January 1, 2025 by Mark Sammut: As the Winter 2025 season is now underway, a few more confirmed harem anime have been added. The article will be updated further if more shows reveal themselves to be part of the genre.

Winter 2025

Medaka Kuroiwa is Impervious to My Charms

Medaka Kuroiwa is Impervious to My Charms is only a borderline mention since the first season might only sprinkle in some harem goodness. Beyond that aspect, the manga has a clearly defined female protagonist, Mona, who is the story’s main driving force, more so than the male lead, Medaka. That said, Medaka Kuroiwa is Impervious to My Charms still qualifies as a comedy harem.

As he is training to be a monk, Medaka must resist all Earthly desires, including girls. Not knowing this fact, Mona is bewildered by Medaka’s lack of interest in her, especially since she is the school’s IT girl who everybody loves. As she cannot live in a world where she is not adored by everyone, Mona decides to convince her schoolmate of her charm. In due time, other girls become interested in Medaka.

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 also a full-blown harem, with Kenichi utilizing his unique ability to set up a comfortable life for himself.

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 reverse harems. 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 should be 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.

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

Arguably the most highly anticipated harem anime coming out in 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.

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.

Spring 2025

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 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.

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.

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.

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.

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 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.
