Most of ppl don't care such minor mistakes, though. If I can follow the story through their translation, that's great enough.
Please tell me if it had any mistranslation that made me get wrong any part of story.
I don't know about other things, but I like the guy. And the idea that "isekai-ed from even another fantasy world" is brilliant. Over all, I think that it's not great, but not so bad as well. At least, it's readable. There are tons of isekai manga which are worse than this one thousand times yet...
