Whooooa, some REAL serious business here. I always thought of Kahi's voice being a heavy British accent, I forgot the names of the bright red mask and orange Miru, for me though, the bright red mask guy had a light british voice, Ennar's being a New York American accent, Tavaki having a heavy Russian accent, Vahi having a Oriental accent, Chinese more specifically, and the guy with the orange Miru having a very light spanish accent. I dunno why.
