One of the worst hentai anime I've ever seen. The plot is not bad. It had some potential, but unfortunately it is totally unused. Characters and dialogues are obviously bad, but it is usual for this genre, so it's not a big problem. Main problem consist in sexual scenes themselves. They are not just absolutely unpleasant, but they are actually very poorly visualized. Although animation may not look bad at first, the processing of sexual scenes, or imaging of sexual organs (if you want), is terrible. /Why is the color of the genital organs green or blue?/ The final five minutes (incest threesome) is already top ofbadness.

Since it isn't bad only technically but also in sexual content, I have no choice but to rate this anime with the lowest score (1 out of 10).
