@Trad who are both Chinese? Are you talking about Chao?
I hope you are aware that Negi is 100% guaranteed Welsh.
Its kinda strange I've been starting to hope Ayaka would be it lately, which is something I thought would never happen.
Currently, I think that Konoka is one hell of a likely candidate. I mean she is effectively the princess of Japan's magical nation, has top class magical potential and their fathers were namaka. This doesn't even address her personality which is also great.
