Note to TL: Since the author made their origins come from Japan, it's safe to say that their names would use the "Japanese-like" name rather than the Chinese translation. As well for the family name, If I'm correct, 雪 would be the character used for snow. It is romanized as "Yuki" and used for pronunciation, rather than literally "snow"
So her fullname would be Yuki (Surname comes first) Yuyuki
Thanks for your hard work!
