Best Harem Anime for Summer 2026: Fresh Picks and Classic Favorites
Summer 2026 is rolling out with plenty of major anime titles, but only a small slice openly leans into harem territory—so players looking for multi-love chaos will need to hunt a little deeper than the usual season headlines.
Summer 2026 Harem Anime To Watch
As a new season begins, fresh anime shows are landing across Crunchyroll and other streaming services, all competing for attention. Summer 2026 looks like a strong one on paper thanks to series such as Bleach, Mushoku Tensei: Jobless Reincarnation, Saga of Tanya the Evil 2, Smoking Behind the Supermarket with You, and Grand Blue Dreaming—but none of them are true harems. You can argue that Mushoku Tensei teeters in that direction, though the case is pretty stretched.
Aside from one sequel, the slate doesn’t include anything that screams “harem,” and very few series openly market themselves as belonging to the genre. Still, if you look closer, you can find a handful of shows that dabble in multi-romance setups, even if it’s secondary to action, fantasy, or comedy. If you specifically want harem energy this season, the recommended starting points are:
- The 100 Girlfriends Who Really, Really, Really, Really, Really Love You Season 3 — The biggest harem attraction is back. 100 Girlfriends returns with the kind of exaggerated chaos that has essentially become the genre’s backbone for the whole year. By now, most viewers know what to expect, and this third season is positioned as something even stronger and stranger than what came before.
- The Villager of Level 999 — As a heads-up, the other harem-leaning picks in Summer 2026 tend to be fantasy stories. In this one, the world runs on leveling, but most people never meaningfully improve their baseline stats. Rex is labeled as a hero, while the seemingly weaker Kouji is actually the strongest person around—though he tries to stay low-key. The show’s twist is that Rex begins with a group of female companions, while Kouji mostly sticks close to Alice.
- I Became a Legend After My 10 Year-Long Last Stand — This also follows the “looks weak, is secretly absurdly strong” idea. Luck spends a decade fighting the Demon Lord’s forces alone, absorbs so much power that he gets de-aged back to his teen years, then chooses to start over as a low-level adventurer. As he grows, he starts collecting followers and building a party. The expectation here isn’t necessarily a full-on harem, but it should flirt with the concept.
- The World’s Strongest Rearguard — A Summer 2026 isekai pick that leans into the “support role” angle. Arihito functions as the party’s main support, boosting the others’ combat effectiveness. There’s also a notable dynamic: he’s the only guy in the party. With the exception of 100 Girlfriends, this is described as the season’s most straightforward harem option.
If you’re trying to track what’s airing this season, the article also notes a streaming guide covering where to watch each series across Crunchyroll, Netflix, Prime Video, HIDIVE, and Hulu.
Ranked Picks: Notable Harem (And Harem-Adjacent) Anime
40 The Testament of Sister New Devil
A Battle Harem With A Lot Of Fanservice And Not Much Else
The writer says they generally avoid direct comparisons and prefer judging a series on its own merits. However, while rewatching The Testament of Sister New Devil, they couldn’t shake the feeling that it functions as a weaker take on High School DxD.
They point out that the characters have similar designs, and that both shows mix fanservice with battle shonen action and hints of romance. In both cases, the male lead isn’t portrayed as helpless, and he unlocks a strange power while becoming the center of attention for a group of girls who slowly grow attached. The main female cast also shares a redhead-heavy look. Both series lean into ecchi content more heavily than many other harem anime, and the presentation is described as particularly risqué.
The conclusion is that while High School DxD is praised as a strong harem and a decent action series, The Testament of Sister New Devil lands as a decent harem but a weak action show. It’s recommended only if you’re specifically after a fanservice-heavy experience that doesn’t hold back—the main source of its value. The characters aren’t called outright awful, but they’re described as one-note and overly familiar, with Basara (the male MC) being “too cool” in a way that undercuts the charm.
39 Arifureta: From Commonplace to World’s Strongest
An Isekai Harem Anime That Starts Really Rough But Gradually Improves
The writer stresses that first impressions are hard to recover from, and says Arifureta struggled at the start. Even though the light novels and manga are said to be well-regarded, the anime’s first season is described as notably rough: it rushed through the story while using animation quality that the article calls substandard. The sequel seasons are said to have helped stabilize things, but the adaptation still hasn’t matched the source material’s quality. Even so, when judged on its own, Arifureta is called a passable isekai power fantasy.
With so many generic isekai entries available, the article frames the series as one that fans shouldn’t miss. It also describes Arifureta as “kind of a weird harem,” because the story takes time before fully committing to that direction.
Early episodes focus largely on Hajime and Yue, creating a dynamic the article says feels like it could be soulmate-level. When other girls enter later, the writer argues they can get in the way of the central romance—even if those newcomers are still decent characters.
38 There’s No Freaking Way I’ll be Your Lover! Unless…
A Yuri Harem… Yes, One Actually Exists! Pretty Hilarious Too
The writer isn’t sure whether to classify There’s No Freaking Way I’ll be Your Lover! Unless… as a harem or a reverse harem. Yuri harems (and girls’ love anime in general) are described as rare, and this one is said to function in both spaces. The series is included because the writer believes fans who usually prefer male-focused harems may enjoy it too.
Renako wants to move past middle-school awkwardness and actually make friends in high school. She gets her chance when she’s saved by the popular Mai. The problem is that Mai wants more than friendship, a direction Renako resists. They try both kinds of relationships, and the situation becomes even more complicated as other girls start approaching Renako.
The article calls There’s No Freaking Way I’ll be Your Lover! Unless… genuinely hilarious, and says it’s a refreshing change to have a protagonist who’s fully aware she’s being pulled into a harem setup.
37 Chitose Is In The Ramune Bottle
An Anime That Tries Too Hard, But That’s Better Than The Million Shows That Don’t Try At All
The writer argues that harem anime typically avoid risk. Because viewers usually know what they’re going to get, fans of the genre are likely to enjoy new releases even if they don’t stand out much. Chitose Is in the Ramune Bottle is presented as an exception, and the writer says they can’t fully recommend it even to committed harem fans. Still, it’s mentioned because as drama it has enough positives to justify a spot on the list, even if it isn’t a strict recommendation.
Harem stories often feature a “loser” protagonist who eventually reveals he’s actually the coolest, smartest, and most attractive man around. In this series, Chitose begins at that level—and, more importantly, he knows it. He’s popular and somewhat arrogant, stepping in to help people dealing with depression or other problems, though the writer notes he often manipulates them in the process. The character is described as fascinating and detestable at the same time, with his “plans” frequently crossing lines of good taste.
Chitose’s harem is said to be made up of girls who are likable enough, and the structure of each arc tends to spotlight one of them. They aren’t described as outstanding, but they’re positioned as a counterbalance to Chitose’s more problematic traits.
36 In Another World With My Smartphone
A Slow-Life Isekai Harem Anime That Leans Heavily On Tropes (But It Can Be Relaxing)
In Another World With My Smartphone isn’t said to excel at much. The article describes its isekai premise—Touya’s reincarnation—as so generic it nearly becomes parody, even though it isn’t played for comedy. The show also isn’t heavy on action, which the writer says is fine, but they add that it doesn’t really offer much else either. Humor is called harmless and safe, and that’s said to apply to nearly all of the characters.
The article then pivots to the isekai genre’s broader trend: overpowered characters dominate stories, from cosmic destroyers to beings that erase existence.
So what does In Another World With My Smartphone have going for it? The writer says it works as a carefree “slow-life” escape designed to let viewers relax. Touya faces almost no hardship and builds a harem quickly and easily. The girls, for their part, are portrayed as loving him unconditionally, with a harem ending always seeming to be on the way. The writer’s advice is to go in with the right expectations; if you do, the series can be enjoyable.
35 Monster Musume: Everyday Life with Monster Girls
A Harem All About Monster Girls
The writer admits there’s no avoiding the fact that harem anime sometimes overlaps with ecchi. They add that some of the most popular releases lean heavily on fanservice, and insist there’s nothing inherently wrong with that when it’s handled tastefully. Monster Musume: Everyday Life with Monster Girls is described as one of the best-known examples of this pairing, even if it’s not as extreme as other shows that demand being watched in the dark with headphones.
Based on the title, Monster Musume follows a man who starts living with a group of monster girls to help them integrate into human society. Instead of rotating through predictable archetypes or hair colors, the show brings together a lineup of fantasy species—ranging from familiar choices like lamia, harpy, and centaur to rarer picks like arachne. While the girls’ personalities aren’t framed as wildly unusual for the genre, the writer says Monster Musume has some of the most diverse and distinctive character designs in all of harem anime. After a few episodes, the writer says the enjoyment came simply from discovering what new race would appear next.
34 Tsugumomo
More Battle Shonen Than Harem, But Works As The Latter
The writer returns to the point that you need to know what you’re getting from harem shows. Even though they aren’t always devoid of mature or ambitious storytelling, most harem anime are light entertainment featuring humor, action, and fanservice. They rely on familiar templates—taking basic comedy or battle shonen beats and then adding extra waifus. Tsugumomo is described as the most “harem action” anime that ever harem, making it an easy recommendation for genre fans and an easy skip for everyone else.
The series centers on sentient objects. Kazuya ends up partnered with Kiriha—his mother’s obi—which transforms into a girl. Another female character, Kukuri, joins the relationship quickly, and the article notes she’s hardly the only one. The show is said to unfold like a battle shonen, with the core trio taking on different spirits while also getting into silly mischief. The writer calls the series mostly just “okay,” but adds that it leans into fanservice more than the average harem entry. They also note the sequel season is an improvement over the first.
33 Trinity Seven
One Of The Most Popular Battle Harems… It’s Pretty OK
The article observes that while rom-coms are more common, the harem genre sometimes crosses with action, producing shows that attempt to blend fanservice with battle-shonen energy. It claims High School DxD and Date a Live are seen as the “ideal” versions of this combo, but they’re treated as exceptions. Most battle harems, the writer says, don’t land well.
Anime such as Blade Dance of the Elementalers, Demon King Daimao, The Testament of Sister New Devil, and Aesthetica of a Rogue Hero are described as difficult to recommend except to die-hard harem fans, and their action set pieces are said to be among their weakest points. Still, they aren’t called terrible—just very niche.
A better representative example, the writer says, is Trinity Seven, which can be enjoyed for both its harem elements and its fights. The writer clarifies that the action isn’t on par with the genre’s best offerings, but within the battle-harem category, Trinity Seven performs better than most. The power system is described as relatively interesting, though slightly complicated, and the idea of tying the girls to the seven deadly sins is framed as intriguing. Arata is called a strong harem lead who isn’t afraid to be direct, and the girls are portrayed as similar in spirit.
There’s also a brief call to sign up for deeper harem recommendations via a newsletter.
32 The Shiunji Family Children
A By-The-Numbers Harem With A Unique Twist – Everyone Involved Used To Think They Were Related
Because The Shiunji Family Children is based on a manga by the same author behind Rent-a-Girlfriend, the show was always likely to draw notice—especially since it centers on a harem made up of adopted siblings. The writer says they initially expected a trainwreck and hoped for a “trash” kind of experience, noting they enjoy trashy anime.
They add that 2025 is over and the year had plenty of harem anime, then says that despite the setup, The Shiunji Family Children turns out to be surprisingly tame and, more importantly, pretty ordinary.
For the most part, the show is described as a by-the-numbers harem that takes few chances beyond the sibling premise. Even that element is said to be underused, particularly because the girls quickly become interested in someone they believed was their brother for more than a decade.
While it doesn’t deliver the chaotic mess some viewers might have wanted, The Shiunji Family Children is called a perfectly enjoyable genre representative. The characters are generally likable, and the girls are developed enough that they don’t fall entirely into stock archetypes. Arata is also described as a solid main lead who mostly wants to do right by his family.
31 Oresuki: Are you the only one who loves me?
An Underappreciated Harem Comedy That Maintains Its Momentum Throughout Its Full Run
The writer argues that harem is such a ridiculous concept that it practically invites parody. They cite Girlfriend, Girlfriend as an example that cranks up the male MC’s stupidity to absurd levels, producing a humor style that people will either love or hate. If you want a comedy that mocks harem tropes while still delivering the same thrills as standard entries, the article calls Oresuki a fantastic option.
It highlights several reasons. First, Joro is described as genuinely funny, and his efforts to juggle a double life while dealing with a female stalker are said to be a constant source of entertainment. Second, the anime is said to be self-aware enough to avoid melodrama, while still treating its characters like real people rather than turning them into punchlines. Third, the girls are called charming, though there are said to be more of them than ideal. Sumireko is singled out as the standout: Joro’s stalker and the apparent main love interest, who mostly slides into the “straight woman” role as the season progresses. Finally, the writer says Oresuki is structured into clear arcs that help keep the story feeling fresh.
