Hello there, welcome to the RPC! From the sounds of it, I take it your character is a Hyur? Doma is pretty much the equivalent of Japan in FFXIV, and there are in fact Midlanders from Doma, who use old-fashioned Japanese names (names from/based on modern anime and whatnot may not exactly fit the bill, but then again, most people won't know the difference). It would be very easy to write off your character's name as the character being from Doma, or having parents from Doma. Otherwise, your character's in game name could always be a nickname or an adopted name while they have a different birth name that's more compliant with the lore.
