Housekeeping Squadron Clean Keeper is the first game from a new division of Idea Factory called Lupinus, which focuses on moe stuff (as in "mo-eh," not games about Moe Howard, which we would prefer). It's a game about a bunch of young maids who band together to defeat some kind of evil dirt or something.
Mostly it'll be a game about looking at some young girls in maid outfits, navigating a whole bunch of conversation trees, and participating in exactly as many gesture-based cleaning action sequences (which seem to involve giant dirt particles) as Idea Factory thinks they have to put in. While the theme of the game is cleanliness, we seriously doubt Idea Factory's intentions are in any way "clean."
