I've been a fan of adult anime for a long time now with a fairly decent collection of VHS titles. This is my first DVD of such kind, and also the first title I've seen from Nu-Tech. If all of their titles are like Custom slave, I will have little interest in anything else from the company. The plot of the title is rather simple and typical of adult anime; a young girl named Sayako attends a private school that transforms her into a sex slave. The story of Sayako's transformation is highlighted, however, not with views of the girl herself, but from short scenes with her aged parents, which is not the desire I have when viewing an adult title. As most adult anime goes, Sayako is unwilling at first, but over time submits willingly. Unfortunately, the time is short. The animation is a bit bland at times; very simple structures without any details, and while Sayako is pretty, with enormous (for her figure at least) breasts, most of the movie's characters are not well done.
