Animation:
The animation is on par with the main show; expect lots of ecchi and lots of nudity and lots of groping. There's no action in this episode, just a lot of ecchi scenes- if you've made it through the main show nothing here will really faze you.
Sound:
This uses the same OP and ED as the main show, and recycles the BGM as well. Expect the same good performance from the VAs as well, including lots of ecchi groans.
Story:
What I said in the intro pretty much sums up the episode. The first half is ecchi with the harem members. The second half is ecchi with the school nurse. Entertaining if you like ecchi or ecchi-based comedy but otherwise this can be skipped.
Character:
Given the short length, I wasn't expecting much in terms of development. Surprisingly, the show teases that the nurse might have more to do with Basara than what was hinted at in the main show, you'll have to watch it to find out more!
Value:
For half an hour's worth of ecchi, it's rather packed with... ecchi. If you want to test your neighbors, play this at full volume. It's not in any way necessary from a plot perspective, just a fun addition for fans of the show.
