Hello everyone! I am a die hard KH fan and have been faithfully following the series since the day KH I came out. I just started playing KH3D and I love it, however, I do not have a PSP and was not able to play Birth By Sleep and feel as though I have missed out on a good chunk of the storyline. Can anyone fill me in on the real relationship between Roxas, Sora, Terra, and Aqua (I believe those are their names)? And how they all tie into the keyblade war?
