That's the kind of low effort manga that makes people think isekai=shit. From the story that doesn't even attempt to deliver on its premise, to the lazy writing, it's only boredom after reading all my suscribed updates that makes me read through the available chapters, but at this point I know I won't click that "add to library button".
FFS, after the isekai currency=yen, Nauzicaa-ripoff glider and the AK47, what takes the cake for me are the elves in traditionnal japanese hakamas training with japanese bows in a japanese-style archery range.
