OK, so I got Senran Kagura Shinovi Versus. Even the game icon and initial loading screen are NSFW.

The game seems pretty good- appears to be native res, colorful, and super-clean looking. Good framerate with a bit of slowdown here and there. Plays pretty much like a musou game as expected, although in smaller areas. The first stage I tried was a fight inside a typical Japanese high school gym, stage area and all. It appears to be set up so that you are fighting against another girl, but there are other, easily-disposable enemies that appear in waves to assist her. Where things get laughably perverse is when powering up your character (they do the typical anime "magical" transformation with the camera focusing on the chest and rear end) or when enough damage is taken-- their clothes slowly get ripped up and fall off. (you can skip all these cut scenes instantly with X) I haven't tried the other modes and since I am playing this at work, I'm afraid to.

The game is pretty easy to play, but there's no English that I've seen anywhere. Will definitely be surprised if this gets localized.
