for one thing, the dad being the greatest swordsman was biased opinion of the one saying that. was it MC admiring his dad? kinda forgot already about that part.
but I do agree on Ars being overly easy to impress or whatnot, but that's maybe what makes him different from all those cool-headed or laid back Isekai protag.... hmm... well he's currently 11-12, so give him some slack I guess...
as for the peerage ranking? not important at all atm, maybe once he actually start climbing the social ladder in all seriousness, but for now, he's still bobble-headed... lol
