May I just point out that not having a racially diverse cast doesn't make the cast racist. If they were racially diverse, but non-white characters were stereotyped, cliche, or played as inferior, THEN the show would be racist. Also, it could very well be entirely coincidence--for all we know, the writers and character designers could have made the series and started posting episodes, only to realize that all of the characters were white.

With that said, I wouldn't be surprised if almost any of the above theories were true, although I'd say it's most likely to be either a Vale thing or something to do with the moon and sun.
