Chantelise: A Tale of Two Sisters is an upcoming action RPG from the makers of Recettear: An Item Shop's Tale. It will be available on July 29th for the PC on Steam, GamersGate, and "other PC digital distribution networks." You can download a demo now from Carpe Fulgur's website.
The demo contains the game's tutorial and the first few levels of play. It's a dungeon crawler and you hack-n-slash your way through stages of enemies. You can replay any of the game's levels to try and clear the monsters faster, and your best times are saved. I don't usually play Japanese RPGs, but I had fun with this demo.
Some of the dialog is downright hilarious because of its translation; it's worth playing just to read the story.
