On one hand, it's the typical premise of a Japanese teenager getting transferred into a fantasy world. The ability he gets is unique, highly powerful, and activated through an interface straight out of a video game he used to play. Yep, sounds like every other cliche isekai out there.

On the other hand, the fantasy world feels real and is filled with characters who have their own motivations. Entire countries want to exploit the protagonist's powers, so there's lots of politicking and scheming. Others just plain fear him. Some want to befriend him. He has to build himself a place in this new world and for that social maneuvering is even more important than his powers.

It's a weird one for sure: elements of video gamey isekai combined with actually good world building, politicking, and diverse characters.
