Yeah, as for nicknames I'll list it as a nickname even if it's just in another language..but yes, it's just the Japanese name.
How about your KOR Eevee House Sylveon ♀/님피아, LV. 10, UT in return?
Sounds like a fair deal to me! ^^ I'll get Sylveon ready for you. I'll be available to trade after 9pm GMT-3 today, as I'm a bit busy with finals.
