Yeah, they're reskins but technically have different names and still have some unique abilities of their own.

I'm pretty sure language is separate from game region. Like Kanami plays on the West European server (I think, she's living in Germany or Italy when the Catastrophe hit) but she's still has her language set to Japanese.
