I read it to volume 6 of the LN and I’d say….
You’ll be in a lot of disappointment if you’re expecting the story to be immersive, sensible, and reasonable despite the attempt to make it somewhat realistic. It just misses more and more details as the story progresses to the point where you can’t help but sigh, and say “Alright, I’ll treat it as another grade B isekai.”
If you want some isekai realism and otherworld politic I’d recommend Risou no Himo Seikatsu or Ascendance of a Bookwork.
