Meet Hatsune Miku, the most famous Japanese VOCALOID virtual idol! Code-named "CV01", she is an android with the appearance of a young girl with long, turquoise twintails and teal eyes. The concept behind her creation is: "an android diva in the near-future where songs are lost". Her voice has been developed and updated using a synthesizer engine, and she has performed at live virtual concerts onstage as an animated projection.
