Many of the light noveland anime series released in recent years fall within the Isekai genre, such asThe Ascendance Of A BookwormandHigh School Prodigies Have It Easy Even in Another World. In addition, the vast majority of light novels to anime adaptations are Isekai, with the numbers at roughly 85%.

Light novels can also have over 20 volumes, making it difficultfor studios to fit storiesinto one or two seasons. All of this, combined with the inconsistent and slow releases of light novels, means that some Isekai anime series never finish adapting their source material.
8Gate
Gatedoes not follow the usualIsekai trope of the protagonistdying in a car accident or suddenly waking up in a new world. Instead, it brings the realm of fantasy to the real world. The story begins when a portal opens up in modern-day Tokyo, bringing a medieval army and a legion of monsters ready to attack the city. However, the Japanese Self-Defense Force (JSDF) repel the attack and set up a base of operations in the new world.
TheGatelight novel series ran from 2010 to 2015, producing ten original volumes, and the anime series only adapted the first three volumes. Nevertheless, it is a refreshing take on the Isekai genre and is a good read and watch for fans.

Besides the apparent gender-swapping, the anime series does an excellent job of representing the Sengoku Era. The comedic elements of the show also make it fun to view. Unfortunately, with only one twelve-episode season dedicated to the anime adaptation, it barely scratched the surface of the light novel series, adapting only four of the 22 volumes.
6Aesthetica Of A Rogue Hero
The story ofAesthetica of a Rogue Herois told from a somewhat different perspective by focusing on the hero’s return from their trip to the new world rather than their time there. The central premise of Aesthetica is that the inhabitants of the leading world are constantly sent to other worlds to gain supernatural powers and abilities.
The show’s attempt at doublereverse isekai gives its viewersthe best of both worlds. Unfortunately, the show ended without fully adapting its source material and may never get a real ending, as the anime only adopted three of the 11 volumes.
5Death March To The Parallel World Rhapsody

Death March to the Parallel World Rhapsody’s light novel is still ongoing and has up to 26 volumes. However, the anime only ran for one season with twelve episodes that only covered the first three volumes, and with the anime ending five years and no news of renewal, the odds of it getting a follow-up season are slim.

1No Game No Life
Despite its enormous popularity,No Game No Lifeonly had twelve anime episodes and a prologue film. However, notwithstanding the light novel series releases at a slower pace than most, ten volumes of the light novel series have currently been released.
