So, at the time of this review I have read 30 chapters, and I have never read the light novel so I have nothing to compare it to. Now then, let's start this review!

Story-8
Now while the story isn't super original, but it's pretty good. Essentially, OP main character goes to new world without the help of Truck-Kun, and gains a harem with a good amount of Lolis. Not too many, not too few. So while it may get dull at points, it's a pretty good story with enjoy pleasure for everyone, so long as you haven't read the light novel (which is different than a "WN" if anyone knows what that is, there are like 3 or so iterations of this series out there).

Art-8
Lolis drawn well. Waifu material. That's really all I noticed about the art. It's pretty good. That's it.

Character-9
At the time of writing this, there haven't been any horrific characters introduced, and everyone is like-able. There isn't a single character that I truly dislike in this manga. And I really enjoy the Mc's reactions to all the the stuff that his harem members do.

Enjoyment-10
I have thoroughly enjoyed reading this manga, even though there are only 30 chapters out there. I mean, if you enjoy harem mangas with over powered main characters in a "new world" setting with lots of dialog, then you'll enjoy this manga. But if you don't like reading, then this may not be the manga for you as some of the chapters feel like you are reading a chapter in a normal book. Dense with words.

Overall-8
Honestly, the main reason I'm writing this review is because the only two reviews on this manga are pretty negative due to comparisons to the light novel, and since I haven't read the light novel, I can give an impartial review. As I stated in the enjoyment section, I really enjoyed reading this manga, even though it can be a bit chunky (not the translators fault). I honestly can't wait for more chapters to be released, however it is on a month by month release schedule due to the difficulty of translating (again, another issue with the amount of text and redrawing necessary) and the monthly releases. However, if you are interested in this manga, then reading up to chapter 30 is a good stopping point, with no severe cliff hanger and a nice semi conclusion to the story till that point (by nice I mean you feel like you can now wait the month or more for the next release).
