@dzzy739 ...What? How is the goddess in this who acts as the straight man to protagonist's weirdness and just wants things to be done the standard way a "clone" of a character that exists to be useless comedic relief and shoots shitty water fountains everywhere? Are we just gonna say that every goddess that follows the protagonist around and doesn't contribute much is an Aqua ripoff regardless of context?
I feel like KonoSuba got way too popular and people just compare every character to Konosuba's characters even though it only exists in the first place as a parody of isekai. This is clearly a comedy about how stupidly paranoid and prep-heavy this dude is, it would lose all the appeal if there wasn't a character there to react to him and it would just end up looking like another generic power-fantasy, and if the character there to react to him was just as good at beating up demons and shit that would defeat the point.
She doesn't ruin it, on the contrary, her perspective makes the manga.
Plus, it's nice to see a female character that has a realistic reaction to a hot dude of "wow shit he's hot I'd fuck him" but doesn't act all dumb and anime and "kyaaaa" about it, also nice to see a dude that just doesn't give a shit about girls because he's too busy setting up seven proxies.
Unless you want literally every isekai to be Re:Monster in which case yeah I guess she does ruin it, what a tragedy.
