if you haven't read it already, mashle magic and muscles is rlly good: http://www.mangago.zone/read-manga/mashle_magic_and_muscles/

Well most mc in this specific genre get an op cheat and in many cases they got effed up, died and went to past... so add being fed up slash vengeful and having a ton of knowledge that can be considered a cheat by itself... so it kinda males sense that kind of personality... ╮( ̄▽ ̄)╭
Hm... in this genre specifically there's not many laid back mc cuz they usually risk their lives... let me see... my dad it too strong and the strongest manager in history... they are very strong and chose to not work as hunters but have jobs related to it...
There are a lot of this of kind of story recently and I'm not complaining because I like it. BUT why must all MC have the same cocky, know-it-all... hmm I mean self-confident personality? Make me feel like I read about the same guy in different worlds.
