This author decided to risk it by making ugly main characters in his stories, still OP as fuck and with a aharem but the girls don0t just fall for a powerful guy with a pretty face this time.
The bad thing is how humble both MC are, too much for their own good, totally used to being beaten around from society and with a unique mindset that misunderstand everything in the worse way.
I respect this author for lowing some fresh air on old cliches.
I read the TL webnovel and there were some plot holes and bad explanations but still fine if we just ignore them, as the author himself decids to do after a while, I guess the paper version was made better.
This manga having LQ art is because all the good artists are 1: doing their own manga 2: got hired to make a isekai port 3: ask too much money
Even the remake of Tanaka the wizard got a bad artist, at least it looks like this one is getting better.
