Yes, apparently she is the main character of FFXIII. FF versus XIII has the blue haired guy that's on the banner this week.

Maybe it is Lightning, after Cloud in FFVII. Strangely enough, why does Cloud sound cooler than Lightning? Probably b/c I'm used to it and use the word Cloud enough to refer to the guy from FFVII than the puffy thing in the sky. Hopefully Lightning will work in English, though. Somehow they got away with in FFVII, like I think Cloud's name is cool, but hopefully Lightning will work.
