You can call me crazy rating it high as 10, but its just how I feel about the manga so far. There's only 24 translated chapters. I don't have any complaints about low ratings this manga has received. Maybe people precieve differently. But I will explain to you how I felt about Isekai Nonbiri Nouka.

First of all, its a pretty chill manga its all laid out and you just read it. You can't really expect something grand from this manga. There isn't going to be an interesting plot building up, each chapters is a whole new story. You could call it rushed but like I said before don't really expect anything to build up. Well apart the fact each chapter you have a new race joining his civilazation. Like busty elf girls-heh.

The art is actually well drawn, good body shapes heheh. This isn't a completely detailed manga but it has details that look appealing. I also think the design for the main character is fair, I think readers will like the design when they first see it.

Well our main character isn't a character with rich personality. He just a normal guy who just wants to farm and chill. He doesn't really have any ambtiion to make a harem or anything. Farming > Harem.
Apart from the fact he gets gangbanged by the female elfs.

I actually enjoyed this manga because it really brings out the calm feeling and makes you relaxed. It has plenty of nudity, well partial nudity lets call it- quite nice busty girls. Not that I am complaining or anything. I was just relaxing in my bed and reading so...

Anyway.

Overall, I think this manga is suited if you are a lazy and laid out person. You should only read this if you don't expect much from the manga. I think its quite a change to the Isekai meta, since most have a same story where you defeat the demon lord. While in Isekai Nonbiri you just farm and chill.

Edit (09/11/2018):

I noticed the chapters are getting shorter and less interesting. I think kinda lost its fun side. I won't change my ratings now, but at the moment i feel like I'd give this a 7. Since its lost its fun attribute.
