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.

23 Satan Takes On A New Name & Starts Flipping Burgers In The Devil Is A Part-Timer!
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.
He 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.
22 Restaurant To Another World Invites Supernatural Beings To Coexist With Humans
Restaurant To Another World is one of the few isekai series that isn't set in a fantasy world. Instead, the series invites fantastical creatures to take a break from battle to coexist with humans in a quaint restaurant called Nekoya every Saturday. Spirits can come over to the human world, and humans can traverse into the metaphysical.
Restaurant To Another World is an exciting blend of isekai's classic excitement and the cozy atmosphere of the slice-of-life genre. It's not a traditional isekai series, but it still involves world-hopping and bringing characters together from vastly different walks of life.
21 Cautious Hero: The Hero Is Overpowered But Overly Cautious' Title Speaks For Itself
Most isekai protagonists are overpowered warriors who fearlessly charge into battle. Though these heroes are admirable, they're not the most relatable or realistic. Luckily, Seiya from Cautious Hero: The Hero Is Overpowered But Overly Cautious represents the cowards of the world who only charge into battle whenever they're absolutely certain they'll win.

Most people would find it annoying, but given Seiya's circumstances, it's actually a realistic response. Ristarte summoned Seiya to her world to help save it from getting wiped out but was disappointed by his attitude. Cautious Hero is so hilarious and lighthearted that it almost feels like an isekai parody, but it's absolutely worth watching for fans of the genre.
20 Trapped In A Dating Sim Presents A Twist On The Classic Chosen Protagonist
These days, everyone's used to the idea of the protagonist who gets sent to a video game world. Most isekai anime like that though focus on someone who's a chosen protagonist. Every character in the series fawns over them, and the series constantly reminds the viewer how important they are.
However, Trapped in a Dating Sim does the exact opposite. In a world where women run most of the world, Leon Bartfort's only goal is to find a woman who won't take advantage of him. But since he's a background "mob" character, his goal isn't easy. Thanks to his knowledge of the world though, he can stand against the royalty to protect those he cares about. A great comedy series, Trapped in a Dating Sim is an isekai for those who need a better class of protagonist.
19 MAR Combines Battle Shonen Rules With Isekai
MAR, or Marchen Awakens Romance, is from a time before modern isekai, so don't expect the usual isekai tropes. Instead, the series has more in common with popular shonen anime of the early 2000s like Naruto or even older series like Yu Yu Hakusho. The story is centered around a teenager named Ginta Toramizu, who's transported to the world of MAR-Heaven. The lighter gravity and magic of this world grant Ginta better vision and even super-strength.
However, before he can celebrate, Ginta quickly learns MAR-Heaven is under attack from a group of enemies known as the Chess Army. Ginta is forced to work with a number of warriors across the land to protect innocents from the Chess Army. MAR is a great series for those looking for a 2000s-era anime, but who still want to enjoy the fantasy of exploring an alternate, unknown world.
18 The Vision Of Escaflowne Has A Compelling Female Protagonist
Isekai anime almost always stars a male hero. There are some exceptions to this rule, but strangely, it doesn't happen very often. However, The Vision Of Escaflowne stars Hitomi after she gets teleported to a cataclysmic world.
In The Vision of Escaflowne, Hitomi helps Van defeat a giant dragon, getting pulled into the world of Gaea as a reward. Once there, she finds out it's a war-torn world and that Van is actually a king with a price on his head. There are also flying mechs involved, making Gaea one of the strangest isekai worlds.
17 Princess Connect! Re: Dive Is A Rare Adaptation Of A Mobile Game That Isn't Just A Cash Grab
It's rare for an anime adaptation of a mobile game to be anything more than a cash grab by the company, but Princess Connect! Re: Dive proves that there are a few diamonds in the rough in that department. Princess Connect! Re: Dive wholly embraced isekai cliches and told a story where a man falls into an unknown world and turns it around to the point that he doesn't even matter all that much in the end.
However, Princess Connect! Re: Dive is the epitome of all anime starring cute girls doing cute things. It's not a revolutionary premise, but Princess Connect! Re: Dive plays into the trope's cliches and produced an entertaining show because of it.
16 Fushigi Yuugi Is One Of The Forbearers Of Isekai
Fushigi Yuugi started airing in the '90s, so there are no exciting Truck-Kun moments in the series. However, the deuteragonists are teleported into a book and forced to live inside the story.
Fushigi Yuugi is heavily inspired by ancient China and really amps up its fantasy elements to mix a realistic historical depiction with isekai's whimsical nature. Fushigi Yuugi is a great blend of shojo and isekai, and it's one of the earliest of its kind. It's one of the forbearers to the entire isekai subgenre.
15 Isekai Quartet Is An Isekai-ception
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.

14 My Next Life As A Villainess Introduces A New Isekai Subgenre
My Next Life As A Villainess is a mouthful of a title, but it's still worth a watch. The series is the first of the "reincarnated as a villainess" light novels to be adapted into an anime, and it was so well-received it's caused several others to get an adaptation as well. In the beginning, Katarina Claes is a spoiled little girl who's a pain to everyone around her. When she hits her head though, she remembers her old life where she played a video game set in the exact world she's been reincarnated into. There's just one problem: she's been reincarnated as the villain!
Katarina spends much of My Next Life As A Villainess trying to avoid all the dangerous story "flags" for the villain, all of which end in exile or worse. Her change in personality though causes her to amass a harem of men and women alike. It's too bad she's too worried about dodging flags to realize they're in love with her. This series is a fluffy, hilarious watch that serves as a perfect break from more serious anime.
13 Grimgar: Fantasy & Ash Follows A Group Of Novices Rather Than Gods
Most isekai series make their heroes overpowered from the jump. The genre is oversaturated with characters trying to live up to Kirito or Ainz, who can defeat virtually anybody. There's nothing wrong with rooting for an overpowered protagonist. But it's more realistic to see a character start from zero and gradually work up to one hundred percent of their potential.
Grimgar: Fantasy & Ash is set in an RPG. It stars a group of adventurers who wake up with amnesia and have to adapt to their strange new world. However, it's vastly different from other isekai series because it shows realistic reactions to the characters' situations. They were utterly helpless after entering the new world, gradually getting stronger and making it easier for the audience to root for them.

8 Overlord Has One Of The Most Enjoyable Overpowered Characters In Isekai

With his newfound power and army of loyal followers, Ainz decides to conquer the world.

7 Knight's & Magic Combines Isekai Fantasy And Mecha
Sadly for mecha fans, the popularity of the mecha genre has dwindled since the heydays of the '80s or even the '90s. However, isekai has experienced such growth they even have their own mecha anime.

Against all odds, Naofumi perseveres against hate and discrimination to prove what it means to be a true hero.
5 KonoSuba's Humor & Zaniness Can't Be Topped
KonoSuba: God’s Blessing on This Wonderful World focuses on protagonist Kazuma Satou, who gets transported to a new world. Unlike most isekai anime, the series focuses on Kazuma getting into ridiculous yet hilarious situations.
Even though Kazuma's allies include a goddess, a knight, and a magician, things don't go as one might expect them to. The magician Megumin is obsessed with explosion magic. Darkness is a creepy masochist. Finally, Aqua is practically useless despite being a goddess. While not as intense as other isekai anime, KonoSuba is by far the funniest.
4 That Time I Got Reincarnated As A Slime Has One Of The More Likable Protagonists
That Time I Got Reincarnated as a Slime follows the story of Satoru Mikami who, as the title suggests, is reborn as a slime. Following his reincarnation, Mikami renames himself Rimuru Tempest. Thanks to the power of the skill predator, he can absorb the skills and powers of whatever he consumes.
