it's hard for me to understand how this is 7.5 stars
i'm 8 chapters in and he's already defeated sword jesus though some shadow 5 year training arc and the power of deus ex machina "my mom rocked my shit with this once so i win". there is no time spent on fleshing out the world, apparently everyone gets to be a A/B rank adventurer despite it supposedly being a pyramid (even if there are vast differences in skill level they're all the same), everyone sucks relative to how strong they're purported to be despite the MC, etc.
another thing: does he just straight up learn the skills he trains to get or does he replicate them? if the former, then what the hell is the point of classes besides getting like, one free skill. if the latter, then how exactly does he perform a humanly impossible skill (slashing twice instantaneously). in the first place, is he the only person in this world that trains? or is getting constantly destroyed somehow the best form of training?
also: mc literally only cares about breast size trope + child-like, child-appearing, adult woman trope who likes getting sexual + sexual harassment/assault trope
