It’s insanely stupid. It follows so many tropes that you have to dislike it. Is that he MC super weak? Check. Is that there a genius kid? Check. Is there a fighter chick? Check. Is there a fully capable person but they lose their shit in an emergency? Check. The women, who fucking outshine the MC change into this weak, sobbing mess. Oh, and the story? Fuck that shit, let’s cobble some shit together from all isekai and hope from the best.
