Here goes the offical site of the movie "SHINOBI":

Click on the
5th link in the bottom left.
Ayumi's name will appear (3rd name). Click on it, and a brief biography will appear.
The movie looks pretty good, hehe. There's also a trailer. I can't wait to hear Ayu's new song!
I hope nobody have posted that yet.
