When I started watching Shinmai Maou, I expected it to be another stupid little "person-from-another-world-living-school-life" kind of thing. Fortunately, it wasn't!
In this season, ecchi takes one step closer to hentai, if that's what you seek. The story improves a lot as well, specially in the second half of the season. Still not great, but gets better at least.
A fair sequence for a fair series. I'll keep the "recommended" here, because it deserves it.
