An excellent first episode. The graphics felt just a little bit old-school, which brought some nostalgia from years past and the many fantasy series that used to run when I was still watching a lot of anime. So far the production values certainly left nothing to be desired. I hope that will remain true for the whole series.

Rudeus's character has been pulled off quite well, I'd say. I agree with Shinta on that the narrative inner voice is a good detail. It makes Rudeus far more interesting than he would otherwise be. I'd say that's the very strength of an isekai reincarnation setting when pulled off correctly.

I didn't remember Zenith was such a babe. Damn.
