The author has an interesting premise, but so far has done a bad job of presenting it.
Early chapters implied he would struggle with the women he fights due to their strength, but the author then just shows him nearly effortlessly beating everyone.
The female characters starting off aggressive/assertive to the MC become maiden-like when they are almost immediately smitten by him. It's one thing to have them still behave like women in some fashion, but as others have put it, it's quite jarring with how it's handled.
It comes off more of a wish-fulfilment Gary-Stu than a fleshed-out character.
I actually thought the first arc would be him dealing with his would-be rapist and how that's dealt with in that world with how much power/influence she has.
How the classmates and family would behave to the sudden personality change along with notoriety from his fighting capability, but none of that has shown up (yet?).
