Ok so I know Roxas is a nobody and stuff and so's Naminé but how does Roxas pretty much have a heart? Then for Naminé how does she have the ability to control memories when the only special thing about Kairi is that she's one of the princesses of heart? Or is Naminé able to do that just to make the story work? Also is Birth By Sleep a good game? I'm thinking about buying a psp just to play it but is there any point?
