There's also Mugen Souls and Mugen Souls Z, a pair of PS3 JRPGs thatare beyond shameless fanservice games. Good music and voice-acting though and fun enough combat I'd say.

I wouldn't call them good games, while Baten Kaitos is one of the best JRPGs I've ever played. I'm just bringing them up because they're pretty obscure and I fondly remember how otaku baity they were.

All you need to know is the sequel has a mechanic called Fetish Pose and that's the ideal way to defeat enemies. They each have a different kink you have to exploit.
