I sure do love a good isekai series with lots of action! And let me tell you, there’s nothing quite like getting transported to a whole new world and taking down monsters with your bare hands (or magic, that works too). So, I’ve decided to compile a list of the best isekai action anime out there, and trust me, I’ve seen a lot. From swords and sorcery to shonen, these shows have got it all, and I’m ready to share my top picks with you. So, buckle up and get ready for some epic battles and hilarious hijinks, because this is going to be a wild ride of great action isekai!
1. Mushoku Tensei: Isekai Ittara Honki Dasu Part 2
Rudeus and Eris find themselves smack-dab in the Demon Continent thanks to a bright light engulfing their homeland. The fate of their loved ones is up in the air, but they don’t let that stop them from embarking on a journey back home with Ruijerd Supardia as their trusty sidekick.
During their travels, Rudeus gets some tips from a so-called god and ends up saving the Great Emperor of the Demon World, who rewards him with a superpower. But it’s not all smooth sailing as they face unexpected dangers on their quest.
The second part of “Mushoku Tensei” is all about our heroes growing up and discovering new things as they explore different continents with their own rules and customs. It’s not your typical isekai show, and while it still has some cliches, they’re refined in a way that makes the story more engaging.
The second half of the series takes a more dramatic turn, with fewer action-packed moments and more nail-biting suspense. But that doesn’t mean it’s lacking in cool fight scenes. It does mean, though, that the writers had to get creative with the magic and plot devices to keep our heroes alive. Let’s just say there are more than a few instances where you’ll be like, “Wait, how did they get out of that one?” I’m excited to see what happens next, especially with Paul and Rudy’s hilarious father-son dynamic.
2. Tenchi Muyo! War on Geminar
Next we have an action isekai anime with Kenshi Masaki, the younger half-brother of Tenchi, finds himself in a strange world called Geminar after being sent there for unknown reasons. He is soon caught up in an assassination plot against Queen Lashara, the newly crowned ruler of Geminar. After being captured by her bodyguard, Kenshi is made one of Lashara’s attendants as she attends a boarding school for Mechamaster pilots.
Kenshi, who is capable of piloting the Sacred Mechanoids used in warfare in this world, finds himself in the midst of royal politics and backdoor machinations that will lead to a revolution. As he navigates his new surroundings, he discovers that growing up in a home with crazy alien women has made him superhuman and a lady’s man, attracting the majority of the female cast on campus.
Amidst the hijinks and humor, Kenshi must face the final battle to preserve peace in a world that hovers on the brink of destruction. The fight before the rising action ends, though epic and dramatic, leaves something to be desired. Kenshi and the allied forces are too nice to the enemy, leading to a lackluster battle.
Despite the many flaws I just mentioned, the series is split into two halves – a fantasy school-life maids/servants ecchi comedy in the first, and a more action-packed adventure in the second. The story ends with the looming threat of a revolution, leaving the future of Geminar in the balance.
3. World Trigger
World Trigger is one of the few that actually deserves over 50 episodes. The series is all about men vs aliens. These bad boys are called Neighbors, and they can just appear out of nowhere in the city. The Border Defense Agency organization sends in their defense team to take them out. These defenders are all young, 15 to 19 years old. It’s been four years since then, and things are still going strong.
There are all kinds of aliens, with different sizes and functions. And the defense teams get to use the aliens’ own technology against them. Things don’t get too gruesome, because there’s no blood or death in this anime. They’ve got this trion technology that basically means any damage is temporary and everyone gets teleported back to base if things get too intense.
The first half of the anime isn’t even that focused on the whole men vs alien thing. It’s more about the Border members fighting each other in intense action sequences. They use swords, sniper rifles, small guns, and energy blasts.
The best part about World Trigger is that there is no useless shock factor or unnecessary killing of characters. It’s just good old-fashioned isekai action anime, sci-fi shounen – with a side of teenage soldiers and aliens.
4. The Eminence in Shadow
Shadowbrokers are people who go unnoticed but control everything from behind the scenes. Cid Kagenoh wants to be one of them more than anything, and he trains secretly every night to prepare for his rise to power. However, he gets into a fatal traffic accident and wakes up in another world where he finds himself leading an actual secret organization that fights evil. He decides what’s cool and fun, and his actions are guided by that.
The Eminence in Shadow is an action isekai anime that has many heroines, and all of them seem to be drawn to Cid despite his quirks. The isekai is all about action, with Lord Shadow being the world’s strongest character who never has trouble defeating anyone he faces. He even has a nuclear bomb spell that can destroy entire cities in a blink of an eye. The background sound for when he unleashes this spell is awesome.
What’s great about this show is that the Cid isn’t on the side of justice. Instead, we get a lot of great action scenes where fights against the guard and takes on The Cult of Diabolos, which he thinks he made up. He’s a guy who killed himself in the hope of getting isekai’d, and he lies to everyone about who he is. It’s a funny, cunning, gritty, and perfect story.
5. High-Rise Invasion
Welcome to the isekai battle royale! It’s like a real-life anime, complete with rooftop showdowns and mask-wearing killers out for blood. Every day people find themselves transported to this crazy world, stuck on rooftops that are connected by tiny bridges. But beware! The stairs leading down are blocked, so there’s no easy way out.
Mayuko Nise, Our hero, is a girl on a mission to find her brother and escape the madness. But as she journeys through this dangerous world, she starts to realize that the only way to truly save humanity is to put an end to this crazy game once and for all.
It might sound like a terrible idea, but it’s actually entertaining trash. The action is non-stop, and there’s never a dull moment with Sniper Mask around.
Just don’t expect too much from the series, let’s face it, it’s hard to keep up the weirdness and quirkiness for multiple seasons. But I must say I really enjoyed some seriously intense action battles.
6. Sonny Boy
A bunch of students is about to graduate, but instead of getting their diplomas, they get sent to an island in another dimension. They all have special powers now. Some of them try to take charge, while others just cry and eat snacks. It’s like high school all over again! They form cliques, argue, and nobody wants to take responsibility for the situation.
But over time, you get to know these kids and what makes them tick. You also get to see some wacky worlds and even wackier characters. And don’t get me started on the finale – it’s like a trip to outer space!
The show isn’t just mindless fun isekai – it also delves into deep psychological themes and explores the consequences of being trapped in this alternate dimension.
Sonny Boy delivers great action scenes and plenty of humor. The dialogue is complex, I felt it was quite a challenge to keep up with everything that’s happening – in a good way.
7. The Rise of the Shield
The Rise of the Shield Hero is like if you took one part fantasy, two parts adventure, and a dash of action, shook it all up, and poured it into your eyeballs. Our hero, Naofumi, gets whisked away to another world to save it from doom, but instead of being greeted with open arms, he gets slapped with a false accusation and left to rot on his own.
Naofumi may not have the flashy magic and weapons that the other heroes possess, but he’s got a shield that he knows how to use like a pro. Who needs brute strength when you’ve got brains and brawn? The action scenes are wild and intense, with Naofumi constantly coming up with new strategies to defeat his enemies.
The battles are so fluid and dynamic, full of explosions, lightning bolts, and fireballs.
