I remember when I kept rejecting last names given to me by all of you. For the American version of the game ONLY, I have decided their nationalities, as if they were living on Earth rather than a parallel universe. Sora/Roxas, Riku, and Kairi/Namine are Lebanese-Americans. Hayner, Pence, and Olette are Caucasian.

So far, here's what I've come up with:

Sora Abraham
Kairi Shapira
Riku Leila

How do you like it?
