Honestly seems like a pretty lame game. I'm a fan of romance in games/anime, but I just don't get the concept of a game trying to make you love and interract with a character like she were real. It's just plain weird. Making the combat system very secondary is also a downside.
The fact that the girls get stronger with the more clothes they lose seems really interesting. =3
Unfortunally, I doubt it'll be localised because of that very feature.
