The unfortunate thing about isekai is that most of them are adapted from light novels. And while there is no shortage of manga out there to be adapted, it pales in comparison to just how many light novels there are. Truly, there seem to be something close to hundreds on the market and more coming out every day.
Because of that, it can often be easier to simply adapt one series for a season and then move on to a completely different series for the following season. The problem is that some isekai series deserve far more than a single season, and even now fans are still wondering if their favorite will ever get a follow-up.
10 Log Horizon Needs Another Season To Answer Many Of The Remaining Mysteries
Log Horizon's one of the best RPG anime, and it just got a sequel, but that doesn’t mean the story’s done. Viewers have seen the fall of the Round Table, but the story really feels like it’s just getting started. The biggest problem with things is that for now there really isn’t much left to adapt from the light novels.
Despite it being so many years between volumes, the creator Mamare Touno hasn’t created much since then, and the last volume released was back in 2018. Still, the fans deserve a finish to this, and there’s side material that can be adapted until then.
9 No Game No Life Has Had Fans Begging For A Return
People have been begging for another season of No Game No Life since it launched back in 2014. When the brother-sister duo known as “Blank,” a pair that have never lost a game in their lives, are suddenly brought to the world of Disboard, they find themselves dealing with a world that is entirely ruled by games instead of conflict.
The series got all of twelve episodes before ending, but despite the light novel being several volumes in, the fans have only been able to get a prequel film: No Game No Life Zero.
8 The 8th Son? Are You Kidding Me?! Needs To Continue Developing Wendelin's Life As A Royal
Shingo Ichinomiya is a salaryman that wakes up in another world and learns he’s born to a noble family. But things aren’t exactly easy for him, as his family isn’t rich despite being noble, and as the 8th son, he won’t inherit anything from them.
The series leans into power fantasy tropes, but what makes The 8th Son stand out is how it deals with the burden of power. The reincarnated Shingo is forced to deal with people constantly hounding him for things rather than him doing whatever he wants with his power.
7 Arifureta Needs A Second Season To Make Up For The First
From doormat to dangerous main character, Hajime Nagumo is a favorite even among isekai protagonist characters (who are usually known for looking exactly the same). After being betrayed by one of his classmates who was jealous, he had the love of one of their classmates, Hajime, and climbed his way from the bottom of the dungeon to the top endowed with new power.
This needs a sequel as an apology for how poorly the original series was adapted. White Fox normally is superb, but this was a bit of a miss and needs a sequel to both continue the story and make up for what everyone lost.
6 Grimgar of Fantasy & Ash Was A Wonderful Change From The Usual Isekai Fantasy Storyline
This series deserves multiple new seasons. The series goes the opposite way of a normal isekai, showing a group of protagonists who have no idea how they got to this new fantasy world. They know only they have to work together because of their youth and inexperience.
There’s no shortcut to being overpowered here — these characters work for every win they get, and it makes their development all the more engaging. The fact that this series never got a continuation is arguably proof that fans don’t really want isekai that do things differently.
5 High School Prodigies Have It Easy Even In Another World Is Made For Fans Of Overpowered Protagonists
An isekai that leaned into having overpowered protagonists. The main characters are a collection of teenaged prodigies who have incredible abilities full stop. The group’s plane somehow crashes in another world, and together they find their way to a tiny city that nurses them back to life.
As a way of saying thank you, the main characters decide to protect the city from an empire seeking to take over them. For fans of overpowered protagonists, this was an entertaining watch.
4 Wise Man's Grandchild Featured The Most Likable Main Cast In Isekai
Shin Wolford is a young man who has a superior understanding of magic thanks to his time in the real world. This understanding makes him into the most powerful mage that ever lived: even stronger than his grandmother and grandfather, the two legendary mages that trained him.
Rather than using this power to show off, Shin instead chooses to teach his friends, raising their magic level to come close to his. Just in time too, as an evil arises that the rest of the country is no match for. Wise Man’s Grandchild desperately needs a second season at the very least to continue some of the subplots it hinted at. For now, people are stuck trying to read the manga.
3 Knight's & Magic Is Made For Fantasy Fans That Love Mecha
Take a genius programmer and place him in a world of magic where there are giant robots. Turn him into someone who has an intricate understanding of magic thanks to his time as a programmer and the result is Ernesti Echavalier and Knight’s & Magic.
This series very obviously was meant to keep going, and mecha fans deserve a treat, as the series focuses on the development of increasingly cooler giant robots he can pilot.
2 El Hazard Should Be Revived For Fans Of '90s Anime
El Hazard was a franchise in the nineties that was actually rather popular. It was a classic isekai that saw three high school students and their teacher pulled into a fantasy world dealing with a war between two sides.
This series had two different versions — the original OVA series and a television series that takes place in a different timeline. The original OVA could use a complete remake, as well as a sequel that can revitalize some of the nineties' isekai ideas rather than enforcing more protagonists who can do everything.
1 Magic Knight Rayearth Needs The Chance To Be Exposed To A New Audience
Magic Knight Rayearth was a series from the legendary creators CLAMP about a trio of eighth-grade girls that are pulled into the world of Cephiro. A world that is maintained through a being known as a Pillar, who was abducted.
The girls are tasked with recovering the Pillar so they can get back home, and are given both special armor and mecha to fight the enemies along the way. This series had a decisive ending, but they also hinted at a wider universe that could be tapped into, and mostly this amazing series deserves to be revived for newer fans.
