I think some of the answers here are a bit too serious. I remember the first one being hilarious and easy-going, but some of the answers here... I wasn't even surprised when someone answered my Yuyuko question that way... Please lighten up a bit, okay?
Anyway, on with the question...
She'll be called Sugchwie Mei Ling, which is what I got when I entered her name in Chinese characters into Google Translate and then translate it into Korean. People would just call her Korea anyway.
What if you found your way to Gensokyou, only to discover a message there saying that all its inhabitants have migrated to the unknown parts of outer space, never to return again?
