its a VERY cliche isekai power fantasy. The main character might not instantly be a god-like being in this other world, that trope is still VERY much in play in other ways, some bordering on the bottom of the barrel of trash isekai tropes

while the story is somewhat original, every trope has been done before, and done better, while that is not a bad thing, the main character is so passive about just about everything it borders on insane

If you want a good time while reading trash isekai, this is for you, but if you want something with depth you might want to look elsewhere
