Could you at least give a reason, why you persist on specifying the worlds and names of the characters to real places/cultures? I mean, what is the point in this? As stated NUMEROUS times before, even if you base your fanfic of the american version, the names remain Japanese... Now all this just sounds... stupid. I mean REALLY stupid! Dude, you beter listen to all these guys or you'll regret posting that fanfic... Seriously, for your own good... (I mean - Riku Leila!? WTF!?)
EDIT: Unless you want to make a spoof of it. Only then would it make sense.
