I actually didn't realize this got turned into an anime. This may actually be the first anime I've read the lightnovel to *BEFORE* seeing the anime.
Ironically, as much as I avoid anime with high episode counts (say, 100+), I find lightnovels that are longlived to usually be the opposite... (with the exception of some types...generally korean/chinese cultivation.)
That being said, if someone doesn't like harem isekai, there's no reason to bother with this show. I *will* be watching this tonight to see how it translates, and possibly try to figure out where I left off in the novels. I personally found the series an enjoyable isekai jaunt, but I think the delay to anime might bode ill for popular reception. Most tropes have been thoroughly covered in the genre by now, so even though some of this may have been new originally, its old now.
