So I just finished playing Birth By Sleep after finally getting my hands on it and I saw that Kairi was at Radiant Gardens when Aqua was there. I guess my question is, have any of the games really explained how Kairi came to the islands? Like, actually shown a cutscene or something describing it? The only ones I haven't played are Dream Drop and Coded. So if the answer is in those games, then don't spoil me! Also, which game is it in so I can get it?
