Best Harem Anime Of All Time
Beloved for their numerous love interests, harem anime are eternally popular. These are the best harem animes ever made.
Harem manhwa can be entertaining and engaging reads for fans of romance and slice-of-life genres, offering a mix of humour and drama as the protagonist navigates his relationships with the various female characters interested in him. In this regard, here are the best of the genre for readers whose preferences run along these lines.
Updated on June 8, 2025 by Mark Sammut: Harem manhwa are relatively commonplace, although they can be something of an acquired taste. Unsurprisingly, the genre combines with isekai quite often; consequently, two more of the best harem manhwa have been added that specifically involve “trapped in a game” scenarios.

Never Die Extra features the somewhat confusing reincarnation tale of the central character, Evan D. Sherden, who suddenly gets reincarnated into the hit fantasy game Demon War 3. In the game, certain characters called extras die in various ways every day.
Unfortunately, Evan D. has just been reincarnated as the extra whose death scene is most cherished by the game’s production team for its exclusively thrilling graphics, making his death a necessity for the game. However, now reincarnated as that particular extra, Evan D. has his heart set on not dying, putting him on a seemingly impossible quest of survival, whatever the cost.

I Killed the Main Player

- Genre: Action, Adventure, Fantasy

I Killed the Main Player has some good ideas and offers a pretty fun twist on the “trapped in a game” concept, with the protagonist reincarnated as an NPC and the villain being the story’s hero. The former travels back three years after learning that the latter is awful (and has a massive crush on him), and he makes it his mission to kill the main player. Cool idea.

Most isekai anime come and go in one season, but some shows stick around for the long haul.
While the manhwa has some issues, the harem is certainly not one of them. In fact, an argument could be made that the harem is the main reason to read I Killed the Main Player, as it is not only central to the story but also revolves around solely likable characters. The girls are all great, and the male lead is solid as well.

A pretty popular magic academy manhwa, The Extra’s Academy Survival Guide is an isekai about a guy who becomes trapped in a game as a secondary villain who is not destined to accomplish much beyond being a minor obstacle during the early parts of the story. Coming from a noble family, Ed faked his way into a prestigious academy, and his world comes crumbling down when he is disowned by his family and thrown out of school. Despite finding himself in extremely dire straits, the protagonist plans to use his knowledge of the game and general intelligence to survive, no matter what.
The Extra’s Academy Survival Guide has way more going for it than just harem antics, but the latter is one of its selling points. Ed fairly quickly finds himself surrounded by potential suitors, with Janica, Lucy, and Lortelle being the main ones. Along with having great designs, the girls are well-written and come across as fully fleshed-out individuals rather than just love interests.

4 Cut Hero
Anime-Planet Rating: 4.0 / 5
- Creator(s): Gojira-kun
- Genre: Action, Comedy, Fantasy, Romance
- No. of Chapters: 257
- Status: Complete
An all-around great and frequently hilarious manhwa, 4 Cut Hero is worth reading for the complete package rather than just its harem. That’s not to say the latter is lacking or unenjoyable, but it is ultimately a small part of the experience as this is a comedy-fantasy manhwa with harem elements rather than a full member of the latter genre. After defeating the Demon King, Zeed is kind of struggling to find his place in the world, especially since heroes are not really all that important in normal society. As such, he starts expanding his scope by accepting quests and jobs that are not exactly heroic, all the while engaging with characters that he would have previously fought.
4 Cut Hero has a pretty great cast of characters and a willingness to cycle through them. Zeed glues nearly everything together, but he is hardly the only memorable figure. Girls (and love interests) are introduced sporadically, and they are allowed to exist beyond their romantic potential for the protagonist. Characters like Gyel and Zena are entertaining, while Daru is a fun twist on the typical harem partner.

After reincarnating, Su Xiaobai gains the Infinity of Darkness, Long Ming’s strongest ability. However, Su Xiaobai’s new power comes with a very steep price: severe pain whenever he gets an erection. Only when Su Xiaobai finds the culprit behind Long Ming’s death and ascends the throne will he be free from the endless pain.

Webtoon Character Na Kang Lim
Anime-Planet Rating: 4.2 / 5
- Creator(s): Gyeong-min Lee, Jun-hyeok Song
- Genre: Comedy, Romance, Supernatural
- No. of Chapters: 172
- Status: Complete
Comfortably one of the most popular harem manhwa, Webtoon Character Na Kang Lim is kind of the medium’s equivalent of the 100 Girlfriends manga. Both series parody harem tropes while still delivering satisfying stories that fit within the genre; in fact, they arguably are more enjoyable as harems than most conventional manhwa and manga.
Na Kang Lim loves reading webtoons, but his life takes a unique turn when the heroine of his favorite story shows up in the real world. More importantly, death is coming for her, and he takes up the responsibility of saving her. If he or she dies, the day resets, forcing Na Kang Lim to keep trying to keep life moving forward. Naturally, more and more girls eventually transition from webtoon to reality. Strong comedy, likable characters, and a complete story with a pretty decent ending, Webtoon Character Na Kang Lim is just an all-around entertaining read.
