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.

As stealth harem anime is a thing, series will be added if they incorporate enough elements from the genre.

Winter 2025

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.

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.

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.

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.

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.

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.
