I can't speak Japanese, but I know enough /about/ it to know that the meaning of a word or a name depends on the characters used to write it. So just knowing the romanisation isn't enough to discern the meaning of a name.
Therefore, I'd like to ask any speakers of Japanese out there to translate the following for me, both names from a show I've been watching.
Ginko ギンコ
Nui ぬい
This is merely out of curiosity of course but I'd be very grateful!
