Wired's James Verini, on just how real Japan's real-life Rei Toei is:
Miku was “born,” as Itoh puts it, on August 31, 2007, with the launch of her software. The program would soon become popular, but from the start Miku attracted her own fans, and they began riffing.

Creation myths were assembled.
