I hope they make another season. They left it screaming out for one. It was so opened ended. Sure Midori may not be in there, but anything is possible for them to do. They could bring midori back as a spirit figure or she uses another power and returns, or just focus on the first real year of being a co ed school. Which knowing green green would be jokes. Panties, breasts and so much more.

Its somewhere indeed between ecchi and hentai o.o!

I hope if any new info comes available someone posts it here.
