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 considered high art; but they are popular and can be very entertaining, serving as a lighthearted escape from reality. New harem anime always comes out, and 2025's lineup looks to be pretty exciting.

During this year's four seasons, the industry will produce tons of new series and sequels to well-established shows. While they may not attract the same attention as some other stories, these are 2025 harem anime can prove to be highlights in themselves. Let's go through all the ones announced so far.

Since stealth harem anime is a thing, comics will be added if they contain 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 reminds of Make campfires in another world with my absurd skillwhich was rightfully one of the best isekai anime of 2023. But this Winter 2025 series is also a full-blown harem, with Kenichi using his unique ability to create a comfortable life for himself.

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

Undoubtedly the most anticipated harem anime coming out in 2025, 100 girlfriends kicked off with a fun opening season that managed to parry the genre while delivering a surprisingly effective romance. Due to a god-level mistake, Rentarou has 100 soulmates, and he must make them all happy or their lives will be ruined. So he does just that and proves 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 am the evil lord of an intergalactic empire!

Another isekai harem, I am the evil lord of an intergalactic empire! also throws mecha into the mix, which should make for a fun and chaotic series. A hard-working protagonist dies after living the most miserable life imaginable, and is given an opportunity to cut himself free in a new world.

The “wizard” 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. Like Liam, the protagonist is specifically born into the family of an evil empire, giving him the perfect opportunity to be the worst. However, it goes against his nature.

Harem Anime 2025 without release season

A Couple of Cuckoos Season 2

A polarizing anime (and manga) that will test a viewer's patience at times, A couple of cuckoos is a bit strange. When viewed as a silly comedy about mostly horrible people, it's quite entertaining, with the girls driving the man up the wall in often amusing ways.

As a harem or, worse, a romance, the anime falls a bit flat. Nagi has to put up with a lot of stupidity from the rest of the cast, and none of them seem particularly good. 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 an option for life, Chitose is in the Ramune bottle is worth checking out for the sultry protagonists who are more confident and self-assured than the traditional harem lead. While Saku is not without his flaws, he is a pretty popular guy who usually knows what he wants and is good at interacting with girls; but he is not always good at handling 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 get attention.

Rent-a-Girlfriend Season 4

Arguably the most polarizing harem anime of all time, Rent-a-girlfriend has a rather negative reputation, while being among the most famous and well-known representatives of the genre. Rent-a-girlfriend is quite unusual for a harem as the “final” girl has been obvious from the very beginning, with Kazuya very clearly favoring Chizuru over everyone else.

Season 3 was the anime's best entry to date, thanks in large part to a fun movie-based plot that allowed the characters to shine. Season 4 is likely to satisfy fans of Rent-a-girlfriendwhile offering nothing to those who hate it.

The Shiunji family children

From the same mangaka behind Rent-a-girlfriend, The Shiunji family children is significantly less popular than its larger sibling. Yet this upcoming harem anime could be a more well-rounded and typical feature of the genre, potentially making for a simpler but less interesting watch. The harem also revolves around a stepbrother and his stepsisters. So, take it as you will.
