Nova_Crystallis from Twitter has translated some information from Jump concerning some new FFXIII-2 Story details (well, just additional details for some stuff we already knew).
Noel is from the future. He is the last surviving human from his time.
Lightning continues to fight as a knight protecting a shrine of the goddess Etro in Valhalla now.
With Tokyo Game Show starting in just under two weeks, we can expect more details to come soon! Remember, the game launches in Japan this December, and makes its way west in January.
