Mary Skelter's purification gag is old before it starts

Having spent some time playing Criminal Girls 2, Mary Skelter offers absolutely nothing when it comes to showing the girls in the game the path to righteousness, or whatever. Sure, Japan probably hasn't had a game like this for, oh, 15 minutes, so I'm guess they'll lap it up. But without even a variety of tickling tools this just seems pointless titillation. Out in October, from Compile Heart, whatever!
