It’s alright so far. I felt like the author kinda abandoned the sister, she was really promising and could have improved a lot. We didn’t even get to see the sister’s reaction when her brother got dragged.
So far I don’t see a lot of contribution from the main guy ourselves. I hope he is like Ainz, morally grey, but so far he hasn’t shown a lot of his skills nor that of a clear goal. Yes, the goal is to become a unstoppable kingdom but so far he is kinda lacking off a bit.
