Due out in Japan next month and North America sometime before the end of days, The Witch and The Hundred Knights is an action role-playing game that looks and sounds like the game you see in the video, because it is that game. I have absolutely no idea what's going on, but it makes me smile. It might also make me dance a little, but I admit nothing.
Hit up the North American website to make a little sense out of all of this. Or don't.
