Isekai (/ˈiːsəkʌɪ/)
This term, born in Japan, literally means “another world”. It was first used in Haruka Takachiho’s novel, Isekai no Yūshi (The Warrior from Another World), published in 1975.
In this type of fantasy fiction, protagonists find themselves projected into another world. Whether by magic, reincarnation, or even through a video game, the method used is of little importance.
The central element to remember is this concept of another world.

To better understand, let’s examine the most well-known types of isekai.
Reincarnation Isekai: The protagonist dies in their original world and is reborn in another world with memories of their past life. For example, Re:Zero.
Transportation Isekai: The hero is physically transported from one world to another, often by magic or a supernatural event. An example is The Rising of the Shield Hero.
Video Game Isekai: The main character finds themselves trapped in a video game and must navigate this virtual world as if it were real. A good example would be Sword Art Online.
Summon Isekai: The hero is summoned by someone else into another world to complete a mission or become a hero. For example, No Game No Life.
Reverse Isekai: Instead of going to another world, the protagonist brings elements or characters from the other world into their own. An example is Gate: Jieitai Kanochi nite, Kaku Tatakaeri.
Return Isekai: After experiencing adventures in another world, the protagonist returns to their original world, often with new skills or knowledge. An example is Digimon Adventure.
However, there exists a concept under-explored in isekai, found in the series Isekai: The Otherworlder’s Heir. Here, it is the protagonist’s descendants who become the main actors of the saga.
