This is actually a game they have released in JAPAN. It is actually a ero game so yeah. Won't put to much up on it but I have been searching for this game for quite a while. So if you guys know anywhere I can get this , than it would be great.
Other than that. Paikai Fansubs took the cutscenes from the game and actually made it into an anime. Its pretty interesting to watch. It wasen't that bad of a 1st episode.
