Isekai is pretty much inescapable, with each new season producing a couple of otherworldly journeys. While not quite as common, harem stories are also staples of most seasonal lineups. Occasionally, the stars align and these two polarizing genres collide, creating isekai harem anime series that are the definition of an acquired taste. Contrary to popular belief, not every isekai story incorporates a harem, and even fewer combine the two in a complementary rather than unnecessary way.
Sure, most OP isekai protagonists are surrounded by waifus (or husbandos), but a show needs more than just numbers to be an enjoyable harem. Therefore, let's highlight the best isekai harem anime, along with mentioning a few weaker examples or shows that incorporate elements but are not fully part of this subgenre.
Updated November 23, 2025, by Mark Sammut: The Fall 2025 season is unfolding, and the main isekai harem anime is Tales of Wedding Rings. If you enjoyed the first season, you will likely love the sequel. If not, you can check out two new additions to this article: Mushoku Tensei and Death March.
Every New Isekai Anime Of 2025
Isekai anime is inescapable, with each season containing a couple of shows. Here are all the 2025 isekai anime series.

As one of the most recognizable isekai anime of all time, Sword Art Online's reach exceeds most of its contemporaries. Consequently, Kirito's adventure is likely to be the first to come to mind when many folks think of isekai harem anime, especially since the protagonist amassed quite a collection of girls by the second cour. The thing is, SAO is a terrible harem.
To be clear, SAO has plenty of good traits. Its harem is just not one of them.
Most harem stories identify their winning girl immediately, to the point that the rest of the competition can lack tension. However, in these cases, the main character has yet to make their choice, so the additional love interests make sense on a narrative level. In SAO, Kirito starts dating Asuna before he attracts a harem, and their relationship remains a fixture throughout the show. Consequently, the other girls have no chance at all, which just makes their one-sided interest a bit sad.

The Eminence in Shadow just barely qualifies for this discussion as it is missing one key factor that defines harems: A male protagonist who shows interest in romantic relationships. Except for a fake romance, Cid does not appear to see female characters as potential partners; however, that has not stopped the protagonist from attracting a literal army of captivated suitors.
Reincarnated with incredible power and the will to live out his chunibyo fantasies, Cid becomes the shadow, an entity that pulls society's strings from behind the curtain. His overwhelming strength leads to the creation of Shadow Garden, an organization consisting of nothing but attractive women. All the female characters have great designs and most of them are completely committed to their leader, even though the latter thinks they are just playing along with his antics. The Eminence in Shadow is an isekai anime with harem tropes but not a full harem.

Mostly an honorable mention, The Strongest Magician in the Demon Lord's Army Was a Human sets up the pieces for a harem but does not do much with them, at least when it comes to the anime adaptation. Despite being a human, Ike was raised and trained by a powerful demon, and he is now part of that race's army. Naturally, he has to keep his status as a human hidden from most of his peers, which is easier said than done. Still, he is a powerful magician who also relies on tactics to overcome most obstacles, be it fights with other demons or an all-out war against humans.
Best Isekai Anime Like The Strongest Magician in the Demon Lord's Army Was a Human
These series share common elements of dramatic power shifts, strategic prowess, and new world adaptation, appealing to fans.
Ike does not seem to have any interest at all in romance, and his circumstances limit what he can do and who he can date. That said, there are about three female characters who seem to be at least somewhat interested in him. Satie is a bubbly human maid, while Cefiro and Lilith are both strong demons. Except for Satie, who does not do much throughout the show, these characters have more going on than just being love interests for Ike.

OK, this is another borderline case, albeit one that sets up the foundation for a harem. While the anime is closer to a (wholesome) love triangle than a full-blown harem, Trapped in a Dating Sim does gradually emphasize the latter aspect in its source material, so it eventually gets there. Crucially, season 2 has been announced, so Leon, Angelica, and Olivia will be making their comeback sooner rather than later.
Most importantly, Trapped in a Dating Sim is just a wildly entertaining isekai anime with an awesome male protagonist and two pretty great female leads. After completing a terrible visual novel for his sister, a guy promptly dies and wakes up as a background character in that same otome game. While he wants to keep something of a low profile, Leon also knows all the tricks and shortcuts to ensure he is extremely comfortable, and he quickly becomes rich and quite powerful. That said, he is still at the bottom of the pecking order at Holfort Academy.
The story mainly revolves around Leon's friendships/relationship with Angelica and Olivia, the game's villainess and heroine. This trio has a charming dynamic that is clearly setting up a three-way romance, which is a lot of fun. Beyond that, Trapped in a Dating Sim is constantly funny.

Death March to the Parallel World Rhapsody is kind of a difficult one to rate for this discussion. In terms of being a pure isekai harem anime, this series is one of the most straightforward and, in theory, should hit the mark with anyone who is specifically seeking out this combination. The thing, Death March is not a particularly good isekai or harem story, but it is an OK isekai harem anime. That might sound confusing, but what it essentially means is that the show does not excel at either genre but incorporates enough elements from both to fulfill this niche combo.
Satou is a programmer who ends up in the RPG he was working on, and he soon becomes overpowered. Satou might look young, but he is an adult and mostly acts like that. Before long, he starts collecting female characters, amounting to seven by the end of the show. The girls are very clearly just there to fit neatly into different archetypes and for fanservice, and they have fairly uninteresting dynamics with each other and Satou.
15 Mushoku Tensei: Jobless Reincarnation
Not The Typical Isekai Harem Anime, But Rudy Gets A Lot Of Attention From Women

Honestly, I'm on the fence about including Mushoku Tensei: Jobless Reincarnation as a recommendation. On the one hand, Rudy gradually gains the interest of quite a few girls, notably Sylphie, Roxy, and Eris. He also has two beastgirls who call him master, so they are essentially extensions of his harem. However, Mushoku Tensei takes a pretty long time to get to the point where its harem becomes obvious, and you have to sit through full seasons where that is not the case. Still, Rudy's relationships with his main partners develop even when romance does not seem to be on the cards.
Ultimately, your love for Mushoku Tensei will come down to whether you enjoy (or at least tolerate) Rudy as a character, as he might just be the most divisive anime protagonist of all time. If you are not particularly interested in following his story, or just straight-up hate him, the harem will be frustrating and unearned. Personally, I really enjoy Mushoku Tensei, but not for the harem.
14 KonoSuba (Kind Of)
An Isekai Parody Will (Obviously) Poke Fun At The Theme's Harem Tropes

While hardly the only option, KonoSuba is unquestionably the definitive isekai parody, especially in terms of popularity (although, The Eminence in Shadow is a close second). As the show pokes fun at nearly every cliché associated with these types of stories, harem punchlines are naturally part of the equation; in fact, the core dynamic essentially mirrors a typical harem setup. Within days of landing in a new world, Kazuma finds himself in a party alongside a female goddess, mage, and knight.
The twist is that all three girls are extremely dysfunctional and cause Kazuma more trouble than they are worth, at least at first. He also does not hesitate to let them know about their incompetence, and the same happens in reverse. More importantly, while Megumin and (to a lesser extent) Darkness show some interest in Kazuma, this element takes a long time to develop and is rarely prioritized.
Basically, KonoSuba is not a harem isekai anime, but it can still be enjoyed by people who love these types of series.

At first, this show seems like another vanilla anime. It certainly takes hints from other shows like Bakemonogatari, but this quickly develops into a rewarding harem. The main cast covers both male and female characters, each with a well-defined, if somewhat basic, personality. Though that isn't to say the show is devoid of a unique romance.
Almost right out of the gate, one of the lead romantic interests is chewing food and spitting it back into the main character’s mouth like some kind of bird mommy. Although that's not exactly what most would call "sexy," it's certainly a nod to other popular romance and harem anime. The harem ends up lacking variety, but there’s plenty of “tongue-in-cheek” fan service, and the main character is way overpowered, making the fight scenes enjoyable to watch.

Villainess isekai anime often plays around with reverse harem tropes, especially if they are set in an otome game. Usually, the protagonist goes out of their way to avoid the main love interests, or they have a specific partner in mind who is not usually an option. From Bureaucrat to Villainess takes things in a few different directions. For one, the reincarnated protagonist is a father who is only somewhat familiar with the game he finds himself in. Secondly, cast as the villainess, he decides that the best way to handle this situation is to rely on his parental instincts.
This decision ends up paying off in both expected and unexpected ways. While trying to improve the heroine's relationships with her five love interests, the MC accidentally causes all of them to gradually fall in love with his character. He is also largely oblivious to this development. From Bureaucrat to Villainess is a pretty hilarious example of an isekai harem anime, although it is certainly more of a parody than a sincere attempt at a romance.

A Safe But Watchable Isekai Harem Anime

Seirei Gensouki: Spirit Chronicles has a pretty interesting hook. A common trope of reincarnation in isekai anime is that the protagonist awakens in the body of a person, usually a member of royalty, and just takes over. Most shows tend to just ignore the body's previous owner or frame it as them regaining memories of a past life, completely wiping out their current personality in the process. Seirei Gensouki tries something different. Haruto dies and wakes up in a fantasy world as a boy named Rio. In a refreshing twist, both characters retain their personalities, cohabiting and co-existing. Ultimately, they just combine their traits, but it is still an interesting concept.
7 Most Polarizing Protagonists In Isekai Anime
These isekai anime protagonists have divided viewers; some fans love them and their journeys, while others find them unlikeable or irredeemable.
Beyond that, Seirei Gensouki is a rather standard isekai anime. Although not absurdly overpowered, Rio is very capable and generally idolized. He quickly forms a harem revolving mainly around Celia and Latifa, although a few other girls join in on occasion. Romance is fairly minimal, so it is more of a case that the characters have very close friendships that occasionally threaten to become something more.
