The isekai anime is called “Summoned to Another World…Again?!” I suspect the title speaks to the synopsis very clearly!
Announced two years ago, the anime is based off light novel series by Kazuha Kishimoto and Shimahara.
A company called Coolmic publishes the English version of the manga and they describe it as;
There was once a hero who was summoned to another world, and he saved that world. However, the man was caught in a “trap” and was forcibly returned to his original world. On top of that, he had to start over as a baby… This is the story of a crazy journey in another world where a former hero who was reincarnated into a slightly gloomy high school student is “resummoned” back to that same world! There’s a lot of room to work with when it’s the second time, huh♪
Motoki Nakanishi will direct the TV anime, which is being produced by Studio Elle. The series is set to premiere in Japan in the spring of 2023.
