Kujonin is not better than the average Isekai. After reading the reviews about it being so, I gave it a shot. Its premise is interesting, yes, but the story itself falls into many of the same patterns that sink the quality of similar manga.
Here's a list of patterns present in Kujonin:
-MC gains power ridiculously fast and easy.
-MC attracts women without having to work for it; one interaction or trait is sufficient for creating this attraction.
-Women near the MC want to have sex at really weird times.
-MC denies all advances from women for no reason.
-Ecchi is random and over the top; there's no flow to
it, and it's often placed in weird spots.
-Vague magic and leveling system.
-Bad pacing (mostly rushing characters and setting).
This list is not exhaustive, but it does cover most of what I think is bad about the story.
So, should you read this? If you're into Isekai stories and don't care much about the quality, give it a read. If you value quality, pacing, etc., this isn't for you.
