11 Best Isekai Harem Anime to Watch in 2023 Yue from Arifureta: From Commonplace to World's Strongest

At the very core of an isekai anime is the protagonist getting transported into another world. However, the main character often gets to have his or her own harem. So, we have a list of the best isekai harem anime you can watch in 2023 right here.

RELATED: Why Are Harem Anime Popular?

  1. In Another World With My Smartphone

    In Another World With My Smartphone is an interesting isekai title based on the light novel written by Patora Fuyuhara and illustrated by Eiji Usatsuka.

    The interesting part is that the protagonist can use technology from his previous life and that’s a game changer.

    After God accidentally kills Touya Mochizuki with lightning, he offers Touya one wish and a chance to reincarnate in a magical world.

    And like any millennial, Touya decides to carry his smartphone into the fantasy world with him.

    The new world is all about fantasy and cute magical girls trying to get Touya’s attention.

    The girls, namely Yae Kokonoe, Leen, Yumina Urnea Belfast, and twins Linze and Elze, are Touya’s companions in the magical world.

    However, they are also part of his harem. Touya and his companions will explore the secrets of this world while enjoying each other’s company.

  2. Death March to the Parallel World Rhapsody

    Dabbling with themes like MMORPG, adventure, and fantasy, Death March To The Parallel World Rhapsody has all the bells and whistles of an isekai with a harem.

    Ichiro Suzuki is a programmer in his thirties and one day, he wakes up to find himself inside a magical RPG world.

    In this new world, he appears younger and his name has been changed to Satou.

    He is ready to go on an adventure that involves beasts, lizardmen, and plenty of girls.

  3. No Game No Life

    There are plenty of isekai anime titles where the protagonist ends up in a video game he is playing.

    However, No Game No Life is slightly different where two shut-ins, who are incredible gamers, are summoned by God in a fantasy world.

    Sora and Shiro are stepsiblings who are excellent gamers but one day they are transported to the fantasy world of Disboard.

    There, they meet Stephanie Dola and join her in her mission to bring back her kingdom’s glorious days.

    However, the subtle romantic tension between the stepsiblings may raise a few eyebrows. Moreover, there is a lot of fanservice in No Game No Life.

    If you are a fan of fantasy and fanservice, No Game No Life might be right up your alley.

  4. The Familiar of Zero

    Based on the light novel Zero no Tsukaima written by Noboru Yamaguchi and illustrated by Eiji Usatsuka, The Familiar of Zero follows Louise, an aspiring musician.

    She is a student at the Tristein Academy and her peers call her Zero Louise because she is a terrible magician.

    Moreover, her spells tend to backfire almost all the time. During an important test, the students are tasked to summon a familiar.

    And at that moment, Louise vows to summon the most powerful familiar.

    Unfortunately, all she could manage is the most generic Japanese boy named Hiraga Saito, who honestly looks like one of those AI-generated male figures.

    Clearly, Louise is disappointed but she is stuck with this familiar. Initially, Louise is mean to him but eventually, Saito’s sincerity changes her outlook toward him.

    As the series progresses, Saito meets other girls in the academy and ends up building his own harem.

    Interestingly, The Familiar of Zero, which came out in 2006, is still immensely popular in the isekai genre. One of the reasons behind its popularity is that it has minimal fanservice.

    Also, the characters are likable and the storyline is crisp, making the anime pleasing to watch.

  5. How Not to Summon a Demon Lord

    How Not to Summon a Demon Lord has all the elements needed for the perfect isekai harem anime.

    Takuma Sakamoto is a real-life nerd who is drowning his time and energy playing a fantasy MMORPG Cross Reverie.

    A summoning spell transports him to this another world where he appears as Diablo.

    Like any other isekai anime, How Not to Summon a Demon Lord has an OP main character who is unbeatable.

    To top it all, his summoners are two girls who eventually become a part of his group or should we say – harem.

    This anime shines in its great comedic writing. It is refreshing to see the anime not taking things too seriously all the time.

    Also, the anime has lots of fanservice even from the first episode.

  6. My Next Life as a Villainess: All Routes Lead to Doom!

    Let’s switch things up with a reverse harem in the isekai genre. My Next Life as a Villainess: All Routes Lead to Doom! is romantic-comedy with a great plot.

    In order to succeed in the already oversaturated isekai and harem genre, the story, characters, and pacing of the plot need to be nothing but exceptional.

    Fortunately, My Next Life as a Villainess: All Routes Lead to Doom! is right up there, and it is incredibly hilarious.

    After regaining memories of her past, the otaku girl realizes she was rebirthed in a popular video game called Fortune Lover.

    However, she reincarnates as the main villain named Catarina Claes. Funnily, in the game, Catarina dies after every route.

    Now, she must find ways to end the depressing cycle of death in the game.

    Apart from Catarina, the other characters, namely Keith Claes, Nicol Ascart, Alan Stuart, and Geordo Stuart have interesting backstories that play a role in the game.

    My Next Life as a Villainess: All Routes Lead to Doom! is indeed a must-watch for its lighthearted and clever storytelling.

    And of course, the waifus and husbandos in the anime look pretty darn cute!

  7. High School Prodigies Have It Easy Even in Another World

    Not one, not two, but seven characters get transported to a medieval world called Freyjagard after surviving a deadly plane crash.

    These seven characters are high school students who excel in magic, journalism, medicine, business, swordplay, and politics.

    After waking up in the Elm village of Freyjagard, they are taken care of by elf Lyrule and a group of animal-eared beings called Byuma.

    A politician named Tsukasa is leading these prodigies and he wants them to gather intel about Freyjagard.

    He also instructs them to learn about the culture of this medieval world.

    However, Tsukasa advises them to keep their guards up and find out why they were taken to Freyjagard.

    The plot may appear a bit generic but we really liked that each of these characters was given importance in the grand scheme of things.

    The character development is a tiny bit choppy in the progression but the variation of the plot somewhat makes up for it.

    The harem in High School Prodigies Have It Easy Even in Another World is decent with passable fanservice moments.

  8. Arifureta: From Commonplace to World's Strongest

    Arifureta: From Commonplace to World's Strongest follows a 17-year-old otaku named Hajime Nagumo.

    Hajime’s life changes when he and his classmates are summoned to another world. They are instructed to save humankind.

    All his classmates are gifted with unimaginable powers except Hajime. Average Hajime is backstabbed by one of his classmates and the protagonist ends up in the depths of a dungeon.

    However, Hajime decides to become the most powerful human without any superpowers.

    This action and adventure isekai is pretty intense in the fanservice department.

  9. The Master of Ragnarok & Blesser of Einherjar

    The Master of Ragnarok & Blesser of Einherjar blends Norse mythology with isekai, giving the historical anime an interesting spin.

    Yuuto Suou and his childhood friend, Mitsuki Shimoya, set out to test an urban legend.

    When Yuuto uses his smartphone to take a photo of himself with the shrine’s divine mirror, he is transported into this world filled with Norse myths.

    He uses the knowledge he gained from his history class and from his phone, to revive the Wolf Clan who cared for him.

    In the meantime, he gets praised by a unit of warrior maidens called the Einherjar.

  10. Outbreak Company

    What happens when a country tries otherworldly ways to spread its culture?

    A mysterious test and an interview result in Shinichi Kanou getting the job of his dreams.

    This job involves the use of his immense knowledge of anime, manga, and video games.

    However, when he meets his employer, he ends up getting kidnapped. Later, he awakens in a parallel fantasy world.

    Turns out the Japanese government selected him to improve Japan’s relations with this new world.

    Now, Shinichi is tasked to open a company and spread the otaku culture in this new and untapped market.

    Outbreak Company is a wholesome anime that is quite funny. Romance is not the prime focus of this series, but the amount of fanservice it has makes it incredibly PG-13.

    The chemistry between Shinichi and Myucel is cute and something to look forward to.

  11. Dog Days

    In Fronaldo, the Republic of Biscotti comes under heavy attack by the Lion Kingdom of Galette.

    Fearing defeat, Princess Millhiore summons a hero who can protect the country.

    However, she ends up summoning a middle-school boy named Izumi Shinku from Japan.

    Izumi arrives in Fronaldo and is asked to become a hero strong enough to defeat the enemies.

    Moreover, he will need to learn the strange rules of battles in the other world of Fronaldo.

    An absolutely fun title in the isekai genre, Dog Days is a comedy anime with action.

    Despite being a harem anime, it appears somewhat innocent with mild fanservice.
