They said that they will go to Hong Kong from 2/9 to 2/11,
and have a live stage at the C3 event.
Aoi said, "For more information, check out the home page.
But it's in Chinese, so good luck!"

(It looks like the stage is 2/10..)

Yuuko said on the Konohana Kitan radio show that she will be going
to Hong Kong soon, so I guess this is it.
