This 3-episode series was so bad, that not even Itou Shizuka would have saved it. Which was a huge shame, unfortunately.
This adaptation is definitely far less superior than the manga version. I do agree with a reviewer that it would have been better off as a Hentai series. As for the characters, the one I liked the best was the sexy and sultry Miyoshi Manami (voiced by Itou). The worst of the bunch was easily that brutish, sunglasses-wearing guy (I refuse to write down his name) who was a huge pervert along with some of the other creep boys from Episode 2.
Well, at least the main male character isn't as bad as those guys. That is the guy that I am rooting for in losing his virginity before the creeps do (unless they already lost it). Also, the other part that I liked about the anime initially was iRis' performance of Hachamecha x Strike during the ED (I don't know how to put the star in the group's name)
If you are still curious about the series, I recommend reading the manga first. That way, you will probably avoid wanting to watch the anime.
That is all.
