Flower Gazer. Hatsune Miku.

A leader of a Japanese music trend, Hatsune Miku is a vocaloid. A vocaloid is like a musical instrument in a way, where you can create a vocal track for a song. This instrument is given a persona as the vocaloid software simulates a voice. Hatsune Miku is the first vocaloid in the vocaloid 2 range, so her voice is not as smooth as some later vocaloids. Fans of Miku make songs and music videos, but few are released officially outside of Japan.
