Writer Nikukyuu along with producers Shiyuuta Biwajima and Chikara Niki tell the thin but adequate tale of a young doctor who, due to sexual indiscretions with his patients, is happy to leave his small town and investigate an unusual disease affecting an island of hot young nuns. Once there, he finds that both he and an agent of Satan enjoy ensuring that there's little virginity to be found in the convent, assuming that well-intended lesbian rape doesn't count toward deflowering.
This is part of the Critical Mass Vanilla Series, which oddly enough means it's an adult release that features not only hardcore sex but also S/M. The animation is simple but images are sharp and bold, with deep colors and refined black levels. Viewers can listen to the feature in English or Japanese, with or without English subtitles. The still gallery includes some excellent and diverse images.
