showcase the diverse appeal of isekai anime.

As a seasoned anime enthusiast who has traversed through countless realms and dimensions, I must say that Kyo kara Maoh! is one of those hidden gems that deserves more recognition than it gets. Having spent many years immersed in various worlds, I can attest to the fact that this anime offers a refreshing twist on the traditional isekai genre.

Right beside shonen, isekai stands out as one of today’s hottest anime genres. This type of storytelling revolves around ordinary individuals who are either transported or reborn into extraordinary worlds. By doing so, they leave behind the mundane routines of everyday life. It’s not hard to understand why this genre has gained such a rapid following. Some of its most renowned works have grown into entertainment titans and even spawned fantastic isekai video game adaptations.

If enthusiasts of this genre voice one criticism, it’s that they yearn for more episodes of their beloved anime. Regrettably, many contemporary isekai series tend to be brief and seldom surpass the 20-episode threshold. However, fortunately, there are a select few that have endured beyond this limit. Here, we present an array of long-running isekai anime, listed according to their episode count. Some may seem familiar, but a number have been incorporated that are so ancient they precede the current isekai craze.

10 Aura Battler Dunbine

Ran From 1983-84, Has 49 Episodes

The Longest Isekai Anime With The Most Episodes

Release Date: February 5, 1983
Creator: Yoshiyuki Tomino
Genre: Action Adventure, Sci-Fi
Streaming Services: Prime Video, Roku

One of the anime on this list, Aura Battler Dunbine, was produced before the isekai genre was classified. Debuting in 1983, it spanned 49 episodes in the following year. Not surprisingly, it gained popularity due to its creator, Yoshiyuki Tomino, known for his work on Astro Boy and Gundam. The protagonist of this anime is Sho Zama, an earthling who ends up in the magical realm of Byston Well after crashing during a motocross competition against a rival.

In a typical medieval Europe-inspired fantasy world like many isekai series, Byston Well introduces an intriguing twist: colossal mechanical beasts inspired by insects, known as Aura Battlers. Unlike other inhabitants, these machines run on a mystical energy source called “Aura,” and Sho possesses an abundance of it. The narrative follows Sho being conscripted into a war engulfing Byston Well, receiving his own mech in the process. To this day, fans cherish the show for its thoughtfully crafted plot and unique blend of mechs, fantasy, and isekai elements. Similar to Yoshiyuki Tomino’s other productions, Aura Battler Dunbine can tackle weighty themes, and it’s an anime where no character’s safety is guaranteed. Forty years later, the series remains a strong contender for one of the finest isekai mecha anime.

9 Paul’s Miraculous Adventure

Ran From 1976-77, Has 50 Episodes

Release Date: October 3, 1976
Creator: Hiroshi Sasagawa
Genre: Fantasy
Streaming Services: Plex

The question of whether “Paul’s Miraculous Adventure” is the oldest Isekai anime is open to discussion, but it’s undeniably one of the first. On his tenth birthday, the protagonist Paul receives a stuffed dog named Pakkun as a gift from his parents. Unbeknownst to them, Pakkun is in fact the guardian of a gateway linking our world with a magical realm known as the Land of Wonders. When he uncovers this secret, Paul and his close friend Nina take a brief trip through it for an exciting exploration.

The story begins with things going smoothly, but takes a turn for the worse when the main character Nina gets kidnapped by the villain of the anime, Belt Satan, who governs the Land of Wonders. Paul tries to save her, but fails and is compelled to return home without his friend. This upsetting event leaves Nina’s parents blaming Paul for their daughter’s disappearance. In an effort to rescue Nina, Paul revisits the magical land, battling various monsters using his mystical yo-yo (it was the 1970s). Although it may not be enjoyable viewing now, Paul’s Miraculous Adventure offers a fascinating glimpse into the roots of an emerging genre and features many elements typical of isekai stories, such as a protagonist unwillingly transported to another world, a fantastical setting, and a hero driven by revenge in an unfamiliar realm.

8 Overlord

Ran From 2015-2022, Has 52 Episodes + 1 OVA

In essence, “Overlord” isn’t immediately striking compared to other contemporary isekai anime, but it offers a unique take on the genre. The story unfolds in the year 2126, where our protagonist, Suzuki Satoru, immerses himself in “YGGDRASIL”, a more advanced version of today’s MMORPGs. This game has been operational for twelve years and is due to be shut down. As a dedicated enthusiast, Satoru assumes the role of Momonga, the Lich Overlord of the game’s most formidable guild. On the final day of the game, he invites his fellow players to gather one last time. However, they fail to appear, and as he waits for the servers to go offline, a strange occurrence takes place – Momonga finds himself still logged in, seemingly trapped within the world of YGGDRASIL.

Instead, he finds himself in the realm of YGGDRASIL, occupying Momonga’s body without any clear reason given. Intrigued and determined to find answers, he ventures out to search for fellow players while unraveling the enigma surrounding his predicament. Despite its common “stuck-in-a-video-game” premise, Overlord distinguishes itself. For one, it’s significantly darker than most isekai anime, filled with morally complex characters and graphic violence that can be quite brutal. Momonga, as a Lich Overlord, serves as the antagonistic protagonist, often behaving accordingly. The series remains popular, with the film Overlord: The Sacred Kingdom having been recently released. Given the complexity of its lore, it’s recommended that viewers familiarize themselves with key details before watching it.

7 Digimon Adventure

Ran From 1999-2000, Has 54 Episodes

It can be said that Digimon was a blatant effort to capitalize on the Pokémon craze of the 90s. However, it is true that many 90s kids cherish memories of watching the original Digimon anime. Digimon is an isekai anime where seven children find themselves in the Digital World after Digivices mysteriously appear before them at a summer camp. In this strange new world, they befriend their first Digimon partners and learn they are the “DigiDestined,” meaning they have a mission to save the Digital World and must battle against foes like Etemon, Devimon, and the four Dark Masters.

In terms of its narrative and style, Digimon Adventure differs significantly from Pokemon, being more akin to other isekai anime. Although it didn’t achieve the same level of popularity as Pokemon, Digimon Adventure has left an enduring impact, leading to multiple sequels, spin-offs, and even a recent remake. Over time, it has emerged from Pokemon’s shadow and is now widely recognized as one of the top isekai anime featuring child protagonists.

6 Log Horizon

Ran From 2013-2021, Has 62 Episodes

In a refreshing twist on the “trapped in a game” isekai genre, we have “Log Horizon“, where the game is called “Elder Tale”. Here, around 30,000 Japanese gamers find themselves stuck inside the game when its latest expansion, Homesteading the Noosphere, goes live. For those acquainted with homesteading principles, it shouldn’t be hard to spot what makes Log Horizon stand out from other games in this genre.

Unlike most isekai stories that emphasize powerful protagonists and magical aspects, Log Horizon primarily concentrates on world-building, political intrigue, and economic systems. Instead of engaging in constant battles, the characters, who are trapped within a game world along with 30,000 others, must establish a functioning society to ensure their survival. This involves tackling issues such as governance and trade rather than partaking in numerous epic battles (although there will still be some battle scenes). Shiroe, the main character of the series, is unlike typical isekai heroes. He’s more intellectual and tactical, with his greatest strength being his intelligence. The Light Novel series continues to unfold, leaving fans speculating when they might get season 4 of the anime adaptation.

5 Re:Zero -Starting Life In Another World-

Ran From 2016-Present, Has 79 Episodes So Far

Since its debut in 2016, Re:Zero has been one of the most well-liked isekai anime series. A significant portion of its popularity can be attributed to its creative handling of familiar isekai genre elements. Unlike other isekai protagonists who are transported through methods like entering a video game, being struck by a vehicle, or being murdered, Subaru Natsuki in Re:Zero simply “blinks” into the alternate world it’s set in. Instead of finding out he’s an all-powerful hero, he immediately dies while trying to aid the first person he encounters.

It appears that Subaru possesses a unique ability called “Return by Death.” Whenever he perishes, he miraculously resurrects, only to find himself back several hours before his demise, with all his memories intact. Utilizing this power, he endeavors to save an elf named Emilia, a potential ruler of the Kingdom of Lugunica. In the end, Subaru adopts the role of a butler and employs his ability to shield Emilia whenever possible. His new life is far from glamorous. In this fantastical universe, Subaru is not your typical powerful hero; instead, he’s a vulnerable protagonist who accumulates more deaths as the story unfolds. This powerlessness and emotional turmoil make him a compelling character in the “Isekai” genre, offering a refreshing take on the conventional tropes.

4 That Time I Got Reincarnated As A Slime

Ran From 2018-Present, Has 86 Episodes So Far

At present, “That Time I Got Reincarnated as a Slime” stands out as one of the most popular anime globally. A significant factor contributing to its success might be the rapid yet consistent production of high-quality episodes, OVAs, and films without compromising quality. The main character is Satoru Mikami, a 37-year-old ordinary man who meets an untimely end while trying to protect his colleague from harm on the street. As he passes away, a voice within him presents a sequence of seemingly unrelated queries. Upon regaining consciousness, he finds himself in an unfamiliar world, inhabiting the body of a slime. The solutions to these questions have determined the unique abilities he now possesses in this new form.

The primary humor in this anime lies in the twist that audiences typically assume slime creatures in video games are feeble, yet our protagonist, formerly Satoru but now known as Rimaru, possesses an overwhelming power. As a Predator-empowered slime, Rimaru continually acquires new skills and might, all while forming bonds with more formidable monsters. Similar to One Punch Man, he remains undefeated in combat and often underestimates his own strength. Throughout its course, the anime has cultivated a delightful ensemble of secondary characters, earning recognition for its amusing wit and uplifting atmosphere. Despite intense battle sequences, viewers can rest assured that their cherished monsters are safe from harm. Rimaru’s goal to create a secure and joyful realm resonates deeply with audiences, contributing to the show’s rapid popularity.

3 Sword Art Online

Ran From 2012-Present, Has 100 Episodes So Far

Once more delving into a recurring motif, Sword Art Online stands out as another widely acclaimed anime within the isekai genre. Unlike its predecessors, this series revolves around characters who find themselves ensnared within an MMORPG using a unique VR device known as the NerveGear. On a fateful day of November 6, 2022, no less than 10,000 players find themselves confined to this virtual universe and learn that their only means of escape lies in conquering the 100-level dungeon Aincrad. Facing death within the game or removing the headset will result in a tragic end for them.

It’s fortunate for them that they have Kazuto Kirigaya, one of the most courageous protagonists from the isekai genre, fighting on their side. As a beta tester for the game, he’s well-versed in its hidden aspects and skilled at controlling its mechanisms. He assumes the role of protector for those stranded within the virtual world of Sword Art Online. Across its four seasons, Sword Art Online has grown to encompass various game genres and has fostered complex character dynamics to maintain viewer engagement. This foundation has spawned an anime juggernaut, leading to numerous spin-offs, games, and films based on Sword Art Online.

2 Kyo Kara Maoh!

Ran From 2004-2009, Has 117 Episodes

Release Date: April 3, 2004
Creator: Tomo Takabayashi
Genre: Fantasy, Adventure, Comedy
Streaming Services: Crunchyroll

Despite spanning an impressive 117 episodes and 5 OVAs, the anime Kyo kara Maoh! frequently goes unnoticed by enthusiasts of isekai genre. However, it’s a shame because it boasts an intriguing premise. The protagonist, Yuri Shibuya, finds himself in an alternate world after an unusual incident – being flushed down a toilet by school bullies. Contrary to expectations, he doesn’t drown or suffer an ear infection; instead, he awakens in the Great Demon Kingdom, a realm inhabited by demons. Interestingly, it is revealed that Yuri is of demon blood and is destined to rule this kingdom.

The anime titled “Kyo kara Maoh!” delights in its central concept, offering a blend of fantasy and humor. At its core, it derives laughter from Yuri’s predicament – he’s a benevolent individual thrust into the role of leading a demon realm that yearns for conflict with humanity. Despite its lighter tone compared to other series, it still touches upon profound topics such as leadership qualities and prejudice.

1 Inuyasha

Ran From 2000-2010, Has 219 Episodes

There seems to be a bit of debate among fans about the exact number of episodes in the anime series ‘Inuyasha’. The initial run spanned four years and generated 193 episodes, securing its place at the top on this list. However, five years following its conclusion, another season titled ‘The Final Act‘ was unveiled, contributing an additional 26 episodes. Some viewers might argue that this later season is a distinct series rather than a continuation of the original, due to the delay. Regardless, ‘Inuyasha’ holds the title for the longest isekai anime series…for now.

The main idea behind Inuyasha centers on a contemporary Japanese girl named Kagome Higurashi who uncovers her past life as a priestess from feudal Japan. She’s mysteriously transported back in time to 1496 and finds herself trapped there, where she encounters the half-demon Inuyasha, with whom she develops romantic feelings. Unlike many isekai series that opt for pure fantasy or science fiction, Inuyasha distinguishes itself through its historical fantasy setting. It offered exciting action sequences, but it also emphasized a fierce competition between its two main characters. The storyline can get quite dark, and by the end, its lore becomes intricate. While its artwork and animation may seem a bit rough today, for admirers of historical fantasy and isekai, it remains an enjoyable watch.
