top 10 isekai anime in the world

Isekai (Japanese: 異世界, transl. "different world" or "otherworld") is a genre of speculative fiction—both portal fantasy and science fiction are included. It includes novels, light novels, films, manga, anime and video games that revolve around a displaced person or people who are transported to and have to survive in another world, such as a fantasy world, virtual world, or parallel universe. Isekai is one of the most popular genres of anime, and Isekai stories share many common tropes – for example, a powerful protagonist who is able to beat most people in the other world by fighting. This plot device typically allows the audience to learn about the new world at the same pace as the protagonist over the course of their quest or lifetime.[1] If the main characters are transported to a game-like world, the genre can overlap with LitRPG.

The concept of isekai started in Japanese folk tales, such as Urashima Tarō. However, the first modern isekai works were Haruka Takachiho's novel Warrior from Another World and Yoshiyuki Tomino's television series Aura Battler Dunbine.
