I can say that the artwork itself and the graphical design is great and appeling, alot of attention to details. The story however is filled with plotholes. Yeah sure the sex scenes are decent, but between those scenes there is somewhat lame story, the characters just don't make any sense and it was very confusing overall to follow the story itself. What could I say more? Just another hentai that was adapted from a visual novel. Is it worth watching? I don't really know, it's sure better then alot of other hentai ovas, the concept is interesting, but the performance itself is meh.
