Ok, so a new character has been revealed today and her name is Lumina. Dat chick at the right. You must be thinking whoa ok what the hell SERAH!?!?!? Yeah, same here. The details we know for now is that she likes toying with Lightning and can be a help and hindrance to her throughout the game. Now the deal with her striking resemblance with Serah, I don’t know man. She maybe is a reincarnation of her but that’s a bit farfetched as well. She looks like the lost 3rd sibling of the Farron family. Still, her appearance should strongly suggest her connection with them. We just have yet to know why and how.
Oh well, at least I’m liking her design a lot. Also, a Japanese friend told me that she says: “Liberator? Who do you think you are?” to Lightning in the screenshot.
