i just read your comment, you pointed out some nice point, but i could argue with that.
first of all, she's a highschooler, while her knowledge seems vast, but they're shallow. she's not an honor student that takes major in economic or management. she made mistakes.
yes, indeed she's presented as smart, but the way i feel about how she's being presented is that that she's just justifying her actions and moral. she's not smart. she's actually, pretty dumb. she's the typical highschooler, but i would give her that she got a calm mind about almost everything.
i share your sentiment, but the way you singling the mc is pretty unfair. the world in this manga is dumb, the mc is dumb, and the npc is mostly dumber. heck you could get away just like that at mercenary camp and they're doing nothing, that's pretty dumb. but that's the setting in this fantasy manga. too much realism will ruin it. nonetheless it's still fun to read.
