All I really need to know about Bayonetta, the upcoming fighting game in which you play a sexy librarian with magic hair and guns in unlikely places, is that it traces its roots to Clover Studios, the folks behind Viewtiful Joe, Okami, and God Hand. Sold!

But for those of you curious to know a little more, there's a demo now available on the Xbox 360 and Playstation 3. The full game comes out January 5th.
