I'm watching this show as well...

simply because I want to see what he will do to enhance the quality of living there.
I have to say though.. that other show with the female demon king and hero teaming up and falling in love was better than this so far.
(can't remember the name though... "the demon king is my wife"? Or something
But we aren't far in, so who knows.

I feel like this show does pamper a whole lot more to the "I'd kick so much as in medieval times"-crowd.
It reminds me a bit of Gate in that regard, actually.

Guy talks to an elf, who lived for who knows how long in a forest and their ancestor's ancestors did the same thing
"Do you even thin bros" - "WHAT IS THAT, OH MY GAWD, DO ME RIGHT NOW IN FRONT OF EVERYONE MY LORD"

And don't get me started on that "prime minister in black"

It's basically going in the same direction as Slime.. and I sure as hell hope I'm wrong.
The townbuilding stuff in Slime was interesting for like 1 episode, before he basically got everything for free to create a early-modern japanese city.
