They totally explained Kairi's background.
(SPOILER) She was the princess of Hollow Bastion. She escaped.... I think with her family.... 9 years ago, same time as Cid & the gang. She's still very young, and therefore doesn't have much of a life story yet. She's also very pure of heart, which goes without saying since she's a female lead character in a videogame.
