Isekai is a subgenre of Japanese light novels, video games, manga, and anime where the protagonist gets transported to or reborn in another world. They’re usually tasked with completing a specific mission during their time in this new world they’ve been forced into. In recent years, isekai’s popularity has skyrocketed, resulting in several more isekai anime adaptations.
It’s safe to say that isekai is the most popular type of anime at the moment. Several isekai anime have gone on to become classics because of the rich storytelling, dynamic characters, and immersive world-building that makes every protagonist’s story seem more realistic.
Updated on April 28th, 2023 by Sage Ashford: As the isekai genre continues to expand, not every series has turned out to be a gem. However, there are still some legitimately great isekai anime that fans of the genre should absolutely check out. This list has been updated with even more amazing isekai series.
43 The Reason Why Raeliana Ended Up At The Duke’s Mansion
7 Episodes
One of the newer series on the air, Why Raeliana Ended Up At The Duke’s Mansion is based on a massively popular webtoon. The protagonist is a young woman who was killed, only to be reincarnated into another world as the daughter of a baron. Living the good life, Raeliana should be happy. Only, she remembers she’s living the life of a character she read about in her past life.
A small part of a mystery novel, Raeliana is destined to be killed by the man she’s engaged to. Refusing to suffer that fate, she takes matters into her own hand, trying to manipulate the events and people around her. This includes the true protagonist of the book, Noah Wynknight. However, Raeliana discovers manipulating a genius protagonist is harder than it seems. An entertaining fantasy-romance, Why Raeliana Ended Up At The Duke’s Mansion will appeal to people who thought My Next Life As A Villainness was too saccharine.
42 Kuma Kuma Kuma Bear

Thanks to her incredible powers, Yuna’s got nothing to worry about, and is free to explore the world however she wants. There’s no super important mystery to Kuma Kuma Kuma Bear, it’s just about enjoying a fun series.
41 Total Fantasy Knockout

40 Combatants Will Be Dispatched!
Combat Agent 6 is a guy with plans of making his way up to the top of the evil Kisaragi Corporation. To have a chance at doing so, he’ll have to take on his most dangerous mission yet. Agent 6 finds himself sent to an alternate world where he’s meant to infiltrate the kingdom of Grace.
While there, Agent 6’s actions lead to him being forced to join Grace’s royal knights. Fortunately for him, this means he’s that much closer to fulfilling his goal with the Kisaragi Corporation. However, it comes at a cost: he’ll have to battle against the Kingdom of Grace’s enemy, the Demon Lord’s Army.
39 Kemono Michi: Rise Up
Genzou Shiba is a pro wrestler with a heart of gold and a love for animals.

Refusing to listen to her, he knocks her unconscious with a wrestling move before he escapes the castle.
In this new world, Genzou becomes a monster hunter to meet as many animals as possible, on the way to opening his own pet shop. Kemono Michi is a straightforward isekai for fans who just want to see a guy have fun in a fantasy world making friends with animals and suplex princesses.
38 I’m The Villainess, So I’m Taming The Final Boss
12 Episodes
The popularity of My Next Life As A Villainess has seemingly led to more stories centered on women being reincarnated as villains. In I’m Taming The Final Boss, the protagonist is Aileen, a young girl who realizes she’s the villain of an otome game she beat just after being dumped by her fiancée in the new world.
Being dumped is one thing, but now Aileen remembers her ultimate fate is to be killed by the Demon King, Claude Jean Ellmeyer. If she’s to have any chance of surviving, she’ll have to come up with a plan. Fortunately, she has one: convince the Demon King to fall in love with her. It’s a wacky plan, but with her knowledge of the game, Aileen might have a chance of making it work.
37 The Saint’s Magic Power Is Omnipotent
Proof that not every isekai series has to be a harem to work, The Saint’s Magic Power Is Omnipotent is built around a woman named Sei Takanashi. Sei, alongside another woman named Aira, are teleported to another world in the kingdom of Slantania.
Though the kingdom was meant to summon a single “Saint” for the sake of ridding the world of a monster-creating miasma, they mistakenly summoned two instead. After Aira is chosen as the Holy Saint, Sei is allowed to live her own life as she chooses. However, despite the country’s choices, Sei soon finds herself pulled into the world’s threats.
36 Welcome To Demon School, Iruma-kun
Iruma Suzuki was born to the worst parents ever. They’re so terrible, they actually sell him to a demon. Fortunately for Iruma, the demon only wants a grandchild he can spoil, including enrolling him at the local demon school Babyls. Iruma just has one problem: no one at school can know of his identity as a human, since demons are supposed to eat humans.
Worse, Iruma’s new grandfather wants him to become the next King of Demons, which means he can’t exactly keep a low profile. With one of the nicest protagonists in all of isekai anime, Iruma-kun is worth watching just to see Iruma develop into a person who can stand up for himself. Fortunately, Welcome To Demon School, Iruma-kun is readily available for fans to check out on Crunchyroll.
35 Fate/Grand Order: Absolute Demonic Front Babylonia
The entire Fate/Grand Order storyline is just one long historical isekai. The entire story focuses on Ritsuka Fujimaru and his partner Mash Kyrielight traveling through time to different eras to deal with specific singularities through time to protect the present.
Absolute Demonic Front Babylonia sees the pair travel back to B.C. 2655 Mesopotamia, where the first city of humanity is under siege by both demonic beasts and goddesses alike. With some of the best animated fight scenes of the last decade, this series is a must-watch for any action fan.
34 Uncle From Another World
The isekai genre has been around long enough for some excellent parodies like Isekai Ojisan to surface. In Uncle From Another World, protagonist Yousuke Shibazaki is hit by a truck, and he spends the next seventeen years in a coma. Once he awakens, he reveals he spent the last several years trapped in another world.
Knowing how different the world he’s come back to is, he relies on his nephew, Takafumi Takaoka, to re-acquaint him with the world. Along the way, they create a YouTube channel to show off all the special powers Shibazaki attained in the other world. An excellent parody of isekai and otaku culture, this series is great regardless of one’s feelings about isekai.
33 The Magical Revolution Of The Reincarnated Princess And The Genius Young Lady
Magical Revolution or Tensei Oujo, gets away from many of the usual isekai tropes to tell a genuinely fascinating story. After being reincarnated into a new world, Princess Anisphia wants nothing more than to learn how to use magic, something other nobles can do easily. She spends much of her time focusing on developing magic tools, against the wishes of her father.
However, when Anisphia learns her brother has broken his engagement to his fiancée Euphyllia, Anisphia decides to make Euphyllia into her assistant… and potentially, her wife. Tensei Oujo is a fantastic girls love series with just enough fantasy to keep things spicy. The only issue with the show is its another isekai that could’ve just been a regular fantasy series.
32 Kyo Kara Maoh!
Kyo Kara Maoh! is one of the earliest isekai from the mid-2000s era. The series depicts Yuri Shibuya being transported to another world in one of the strangest possible ways — after being given a swirly. The toilet he’s dumped into sends Yuri to another world, where his eyes and hair denote him as a royal, and potentially the next Demon King.
While still lost at everything happening around him, Yuri winds up in a duel with another high-up demon, and in winning against him, learns his victory is akin to a proposal in this world. An isekai comedy with light shonen-ai elements, Kyo Kara Maoh! works best for fans who want isekai without as many of the modern tropes of the genre.
31 The Devil Is A Part-Timer!
24 Episodes
The Devil Is A Part-Timer! is a brilliant blend of comedy and isekai. Rather than the series’ hero getting teleported from the average world into one of mysticism and adventure, Satan is taken out of hell and sent to the real world. He quickly realizes that he had to make ends meet, so he picked up a part-time job at MgRonalds.
Satan names himself “Sadao Maou” and gets to burger flipping right away. The Devil Is A Part-Timer! appeals to so many fans since the hero doesn’t start out as an average person who obtains godlike powers; Sadao’s story is the exact opposite.
30 Isekai Quartet
24 Episodes
Isekai Quartet combines characters from Overlord, KonoSuba, Tanya The Terrible, Re: Zero, and The Rising Of The Shield Hero into one series where they all attend school together. It’s an amalgamation of some of the genre’s greatest heroes and heroines coming together in the most chaotic way possible.
Isekai Quartet is a campy series that puts each character’s running gags on full blast. It pokes fun at the genre’s most overdone tropes and amps everything up to eleven. It’s one of the best isekai series for veteran fans of the genre.
29 World’s Finest Assassin Gets Reincarnated In Another World As An Aristocrat
12 Episodes
After years of service, the world’s greatest assassin finds himself betrayed by the very group he’d spent years working for. Before reincarnating into another world, however, a goddess offers him the chance to retain his memories if he’ll do one thing for her: assassinate the new world’s greatest hero. This is no easy task, as the hero is born with more talent and power than any other human on the planet.
World’s Finest Assassin gained popularity at launch for being so different from what people are used to with isekai. While the protagonist is technically young, he’s actually got the mind of an older man, and his attitudes towards the world around him have changed as a result. It’s also distinctly less optimistic than some isekai series would lean, while keeping plenty of cool fantasy abilities.
28 Eminence In Shadow
20 Episodes
Eminence in Shadow focuses on Minoru, who wants nothing more than to be control the world from behind the shadows. Minoru spends most of his time training, wanting to obtain magical abilities. It isn’t until he’s reincarnated into another world, however, that his wish is granted. In this new world, Minoru is reincarnated as Cid Kagenou, and forms a group known as Shadow Garden.
Cid’s imagination leads him to create a group for Shadow Garden to fight in the Cult of Diabolos. The only thing is, everyone in Shadow Garden knows this Cult is actually real, except for Cid. Eminence in Shadow is a self-aware parody of all the popular isekai tropes like an overpowered protagonist and a supporting cast obsessed with its lead. It’s exactly the sort of show people for people looking for a break from the classic isekai formula.
27 How A Realist Hero Rebuilt The Kingdom
26 Episodes
Realist Hero proves not every isekai needs to be entirely focused on action. In this world, Souma Kazuya is a man with dreams of becoming a civil servant. One day, he finds himself transported into a fantasy world, where he’s meant to be sent to another nation to help the kingdom of Elfrieden with their debt.
To avoid become a simple “tribute,” Souma decides to pull the kingdom out of debt to allow Elfrieden to pay their tribute. Through smart economic policies, Souma manages to restore the country and is turned into the King for his talents.
26 Re:Creators
22 Episodes
Re:Creators is the best example of a reverse isekai. The series begins when fictional characters from popular manga and light novels begin appearing within the real world. The story focuses on Souta Mizushino, a high schooler aiming to become a creator, working alongside Silesia, a protagonist from another world.
As the fictional characters realize their creators are responsible for their lives, Souta and Silesia must work together to both protect the other creators and discover how their worlds have crossed over. Re:Creators manages to make references to tons of anime tropes while also posing fascinating questions about the nature of stories and what creators put their characters through for “entertainment.”
25 Gate: Thus The JSDF Fought There!
24 Episodes
Gate: Thus The JSDF Fought There follows Japan’s Self-Defense Force going to war against an invading kingdom from another world. Besides forging relationships with the new world’s inhabitants, the JSDF also battles various fantasy world creatures, including a dragon.
Gate does an amazing job of blending both modern-day and fantasy elements, and its use of a much older protagonist received popular reception from fans. In fact, Gate: Thus The JSDF Fought There was so well received that it inspired a collaboration campaign with the real JSDF, which used characters from the anime to bring in new recruits.
24 El Hazard: The Magnificent World
24 Episodes
Long before isekai became a dominant genre in anime, El Hazard was creating some tropes that would become common in isekai series going forward. The story focuses on a high school student named Makoto Mizuhara, who’s sent to an alternate world alongside several classmates and one of their high school teachers.
In this new world, Makoto is confronted by a young woman who claims to have waited for him for ten thousand years. While none of them have any idea how to operate in the world of El Hazard, their actions and desire to get home nonetheless leave the world changed forever.
