Best Shonen Isekai Anime & Manga

There’s a reason why the isekai genre in anime, manga, and light novels is as popular as it is. It serves as the perfect power fantasy. Who doesn’t want to be transported into a fantasy world where they’re more than just a regular human being? Who hasn’t wished to live in their favorite video game world?

With so many isekai works, finding one that caters to a specific demographic shouldn’t be too difficult. With shonen isekai in particular, the protagonists are often teenage boys, and the works themselves borrow some elements from battle shonen. These tend to have a much more idealistic tone than seinen isekai, and are more action-heavy than shojo works.

8 Cautious Hero: The Hero Is Overpowered but Overly Cautious

MyAnimeList Score: 7.48

Cautious Hero: The Hero is Overpowered but Overly Cautious is a comedic take on the isekai genre. A goddess named Ristarte has summoned a human named Seiya Ryuuguuin to protect her world from the Demon Lord. Seiya has incredible stats, but he is a little too cautious about everything.

He demands multiple sets of armor, refuses to enter even the world’s safest areas, and uses his strongest powers to kill the weakest enemies, just to be on the safe side. Given the kind of world Gaeabrande is, though, Seiya’s overly-cautious nature might be justified.
