I feel like I would have enjoyed it far more if I seen it when I was 13. I think that's actually the target audience. There's very little ecchi and humor that would be surprising/entertaining/interesting to late teen/adult. Having said that it's still a pretty good series, easy to watch. Just doesn't really work as well as ecchi or comfort food as I would have hoped. Watch this if you're young and want some light ecchi to start, you'll probably have a blast. You won't have any real weirdness that comes with almost all ecchi with this anime. (you know what I mean, the kind youhave to overlook/not think about or you'll ruin the entire series for yourself, that kind).
It's pretty much the same simplistic light ecchi as S01, so I give it 7. It's good for what it is, that's it.
