Best Isekai Anime With Multiple Seasons

Anime sequels are so incredibly rare, you are better off assuming that every new show will never receive a continuation. Quality does not matter. Still, a few chosen anime get to live on beyond a single season, spreading their glory over years filled with, hopefully, worthwhile storytelling.

Due to being extremely popular and extremely common, isekai anime with multiple seasons are not completely unheard of. That said, only a fraction of this genre’s many series get sequels, and they are not always the best of the best. Heck, The Devil Is A Part-Timer and Log Horizon might have been better off remaining as one-season shows. So, let’s pinpoint the absolute best isekai anime that have multiple quality seasons.

Sword Art Online

3 Seasons (Main Series) – MAL: 7.32

Ah, Sword Art Online, the most popular and also the most hated isekai anime of all time. With 3 seasons and nearly 100 episodes, SAO has quantity covered, and that is not even counting the Alternative spin-off, which is more than watchable. The show’s post-Aincrad sagas are notoriously divisive, with the Fairy Dance arc and Sword Art Online 2 sparking particularly strong reactions.

Best Isekai Anime Like Sword Art Online

If you loved Sword Art Online, there’s a whole world of anime waiting for you to discover. Here are some excellent shows for SAO fans.

Here is the thing: SAO is, for the most part, fairly consistent. The animation quality never declines, each major arc introduces a new game setting, and Kirito is a stable presence who grounds most of the story. While never reaching Fate levels, the action sequences can be spectacular at times, and the game worlds are interesting enough. The storytelling also doesn’t change that much, and arguably improves during the Alicization season. Basically, if you love Aincrad and manage to enjoy Fairy Dance, you will probably like the rest of the series.

Tsukimichi: Moonlit Fantasy

2 Seasons – MAL: 7.78

Tsukimichi: Moonlit Fantasy mostly sticks to the isekai formula, and I do not mean that as a criticism. Here is another show about a down-on-his-luck guy who is sent to another world and, somehow, ends up so powerful that he defeats a Greater Dragon almost immediately. Before long, Makoto amasses powerful followers, sets up a haven for monsters who do not have anywhere to go, and he even becomes a teacher at an academy.

All standard isekai stuff, but Tsukimichi cooks these familiar ingredients in a way that not only makes them palatable but also uniquely delicious. Makoto is likable, and he does not suffocate the rest of the core characters, who are allowed to shine outside the MC’s shadow. The story is quite well paced, too.

The Eminence In Shadow

2 Seasons – MAL: 8.27

Look, sometimes you just want to watch an OP MC pose his way through a chunibyo’s perfect life. While on Earth, Cid wanted to be the shadow who pulls society’s strings. He dies unfulfilled, but he is reborn into a world with magic. Crucially, he is powerful from a young age, so much so that he unwittingly attracts an army of deadly girls who are willing to fight and die for him. As the leader of Shadow Garden, Cid protects his new world against a dangerous cult and entities like the Blood Queen. However, while everyone is deadly serious, Cid is mostly just goofing off.

The Eminence in Shadow is consistently awesome, as long as you enjoy the basic joke that Cid might just be the most oblivious protagonist in anime history. As long as you are on board with that concept, you can sit back and enjoy two great seasons filled with clever world-building, top-notch action, and hilarity.

Welcome To Demon School! Iruma-kun

3 Seasons – MAL: 7.86

OK, here is a bit of an odd one. Welcome To Demon School! Iruma-kun is relentlessly entertaining, and all three seasons are enjoyable to an extent. However, season 2 is comfortably better than its predecessor and especially its successor; in fact, season 3 can be an exhausting watch for most of its run, and it only really picks up steam towards the end of its 21 episodes.

Exams, crushes, after-school hijinks — these school anime explore all the ups and downs of life as a student — in ordinary or extraordinary worlds.

Despite all that, I would still describe Iruma-kun as consistent, just because the series never stops being fun. Yes, some arcs overstay their welcome or focus too much on action over humor and slice of life school silliness, but they are still pretty good. More than anything, Iruma-kun has an incredibly strong and varied roster of characters who are almost all endearing, especially the main trio.

For the uninitiated, Iruma-kun is about a human who is adopted by a demon and taken to the Demon World, where he must attend school while hiding his humanity. Why? Demons eat humans, which is not great for Iruma. Before long, he makes a few friends and starts to live his best life.

Ascendance Of A Bookworm

3 Seasons – MAL: 8.04

Ascendance of a Bookworm has three seasons that are nearly identical in quality, meaning they are all very good with moments of greatness. Urano, the protagonist, is crushed to death by books, only to awaken in the body of a young, sickly girl named Myne, who lives in a world where literature is only for the very rich and powerful. Despite her demise, Myne still loves books, and she makes it her mission to bring the joy of reading to this world.

I love an OP MC, but the exact opposite often leads to more intense stories. Ascendance of a Bookworm emphasizes Myne’s vulnerability and her refusal to back down, all the while highlighting the people who support or try to use her. Her journey is fascinating, and she changes quite a bit throughout the seasons.

5

Overlord

4 Seasons – MAL: 7.91

We all like a good hero, but we also like a good villain. Overlord ponders what would happen if a final boss-style character were to suddenly spawn in a low fantasy world that is not remotely equipped to accommodate them. Even though he does not start as intentionally evil, Momonga’s march forward gradually becomes about world domination, although this desire is primarily fueled by his (powerful) subordinates rather than himself.

Best Isekai Anime With Overpowered Main Characters

Overpowered protagonists are a fixture of isekai anime, and the best series showcase why this concept is so common.

Madhouse’s Overlord has had a few public low points throughout the years, including some moments that went viral for all the wrong reasons. However, animation woes aside, Overlord has never stopped being Overlord. Each season shows a complete commitment to chronicling an overpowered being’s rise to ultimate control, with each chapter expanding the scope and consequences.

KonoSuba: God’s Blessing On This Wonderful World!

3 Seasons (Main Series) – MAL: 8.23

The ultimate parody isekai anime, KonoSuba has, somehow, lasted longer than the many shows it mocks. Why? Well, Kazuma, Aqua, Megumin, and Darkness are the perfect level of dysfunctional, stupid, and arrogant to ensure their adventures are always a laugh riot, as long as they are all together.

However, they can also be kind, fun, briefly intelligent, and relatable, so they are not just walking punchlines with no traces of humanity. KonoSuba has wisely kept its seasons relatively short, eliminating any of the potential fat that could have spaced or stretched out the humor. 2024’s third season was also the best, so the anime just gets better as it moves along.

3

That Time I Got Reincarnated As A Slime

3 Main Seasons + 1 Spin-Off Season – MAL: 8.12 (Main Seasons) Or 7.86 (With Spin-Off)

The most accessible gateway into the genre, That Time I Got Reincarnated As A Slime deserves to be an isekai anime with many seasons, just because it is the quintessential representative. When I think of isekai, TenSura is the first show that comes to mind, despite not being one of my absolute favorites.

That Time I Got Reincarnated As A Slime: Every Main Character’s Age, Height, And Species

The main cast of That Time I Got Reincarnated As A Slime is filled with interesting characters. Here are some basics you should know about each one.

When it comes to the ever-popular OP MC subcategory, no other protagonist has done it as well and for as long as Rimuru, who has spent more than 70 episodes transforming from a lowly slime to a Demon Lord who can stand toe-to-toe with some of the strongest beings in this universe. He has built a kingdom that allows all of its inhabitants to prosper, and they seek to work alongside their neighbors (but are willing to stomp them out if they must). While season 3 spends a bit too much time in a boardroom, TenSura is never anything less than “good,” and it is frequently a lot more than just that.

The Slime Diaries is the cherry on top of this beautiful sundae. The slice of life spin-off shows the daily lives of Tempest’s citizens, and it feels like a substantial extension of the main series (despite mostly consisting of fluff).

2

Mushoku Tensei: Jobless Reincarnation

2 Seasons – MAL: 8.40

Due to dividing each season into two parts, Mushoku Tensei: Jobless Reincarnation has established itself as a fixture of the isekai scene over the last few years. Depending on who you ask, it is either the best or most infuriating show in the genre’s history. The story follows Rudeus, a guy who wasted his previous life, but gets an opportunity to make things right when he is reborn in a fantasy world with almost everything working in his favor. However, he still has a lot of maturing to do, and he is rather unwilling to leave behind some of his less-than-amusing traits.

Honestly, I completely get why somebody would drop Mushoku Tensei because they cannot stand Rudy. He is not a particularly likable character, especially during the first season. That said, Studio Bind deserves credit for maintaining the same high quality through multiple challenging seasons that frequently shake up the status quo, including an entire arc set in a school and featuring almost no action. Mushoku Tensei is one of the most ambitious isekai anime of all time, and it deserves praise for taking risks.

Re:Zero – Starting Life In Another World

3 Seasons – MAL: 8.36

Re:Zero is incredible, and it is also not for everyone. That might sound obvious, but if this anime does not click with somebody, they tend to straight-up dislike it. However, the opposite is also true; if you like Re:Zero, you probably love Re:Zero. Regardless of what reaction someone ends up having, newcomers should give this show a try. No other isekai anime offers a similar blend of psychological horror, introspection, vicious action, slow-building tension, bad humor, and experimentation.

Re:Zero‘s three seasons are very different from each other, with seasons 2 and 3 being almost polar opposites. That said, they all have incredible writing, effective cliffhangers, shocking moments, and well-done character development for the protagonist, Subaru, and important secondary figures like Emilia, Beatrice, Rem, and Garfiel. The world-building is not as good as Mushoku Tensei, and Subaru is not as universally beloved as Rimuru or Momonga, but Re:Zero is just one of a kind.
