I checked and it was after finishing volume 4. I dropped it because her inner monologue made her look dumb/oblivious and because the characters were so inconsistent. Here's a bit of what I wrote at the time:
Also, suddenly she is some damsel in distress who needs to be rescued from some princeling when in previous volumes she was a powerful last boss cheat monster that could annihilate a platoon of bandits that even endangered the army. But no, now some single little prince can manhandle her as he wants. Such fucking inconsistent writing.
And now that I've refreshed my memory I think I will stay away, even if there is country building.

My face when my comfy isekai farming anime has fully animated fight scenes with complex camera work.
