I find this as one of my fav when it comes to hentai. The animation, the voice acting, and the style are all beautiful and erotic. The monster-women rape scenes are one of my turn ons and I must say they did a brilliant job with that and having a beautiful, busty heroine who is actually a shy teen schoolgirl makes it even more exciting. Although the series was short, It kept the storyline in checked with it's brilliant storytelling and imagination. If only the series could've last longer. ;)
