I read the LN (and finished with the WN, because the LN wasn’t fully adapted yet at the time) a couple years ago and liked it decently. I don’t recall too much about it outside the premise and the character growth exhibited in the final conflict.

After watching the PV, this looks like it’ll be a fun show. The animation looks like it’ll be good in some ways and unexceptional in others. I think I liked all the voice actors. A few memories have swelled back up from the gutters of my mind. I think it’ll be a big step up over the fantasy anime that are currently airing.
