The world-building in this series is... painful. "Is that one of those magical silver foxes that can turn into humans?" "Yes, but there's no way it has enough mana to turn into a human!" Then why do they think those foxes can turn into humans? Why does every chapter make it sound like everyone in this world is an idiot? Like that teacher (whose betrayal no one could have possibly seen coming) flipping out and trying to kill his meal ticket as soon as the slightest hitch occured in his plan.
I know that a lot of manga just push the same old tired tropes (gotta get that harem going, right? We got the princess, the maid, and now the beast-girl; any takers on the next one? My money's on tsundere knight) but I have to ask if people actually want that. Is there someone who just refuses to read a manga if the main character isn't just unassailably strong, but also has a coterie of women fawning over him constantly?
I wouldn't be half as annoyed if the mangaka more often than not has no idea what to do with the harem after they're established, instead just adding new girls like the MC is a goddamn pokemon training out to catch 'em all. So all we're left with is a bunch of paper-thin NPCs hovering around a dude who palpably, obviously, has no actual romantic interest in any of them. And when you know that every character is going to exist just to glorify the MC, there's no reason to read the piece for the characters. And when the lore is so shallow and contradictory, there's no reason to read it to immerse yourself in an interesting world. And when the plot is formulaic- well, you get the pattern.
There are ways to make this plot interesting. Novel. I really wish the mangaka actually did, instead of rehashing the same ground half of all isekais seem to go over. Immediate mastery of any magic the MC sees. The MC is the only person that thinks of using magic to benefit people generally. Immediate trust (and love, we know it's going there) from all the women around him. Status menus - fuck, I hate status menus. Should've stopped right there. That's the first sign of shit world-building.
Now I'm just cranky and ranting. Whatever. If you like the series, don't take this as an indictment of you. I just keep hoping for new stories, new ideas, and hate being disappointed so often. It's fine if this is the kind of thing you like.
