Hatsune Miku
, sometimes referred to as Miku Hatsune, is the name of a Vocaloid software voicebank developed by Crypton Future Media and its official moe anthropomorph, a 16-year-old girl with long, turquoise twintails. She uses Yamaha Corporation's Vocaloid 2, Vocaloid 3, and Vocaloid 4 singing synthesizing technologies. She also uses Crypton Future Media's Piapro Studio, a singing synthesizer VSTi Plugin. She was the second Vocaloid sold using the Vocaloid 2 engine and the first Japanese Vocaloid to use the Japanese version of the Vocaloid 2 engine. Her voice is modeled from Japanese voice actress Saki Fujita. Miku's personification has been marketed as a virtual idol and has performed at concerts onstage as an animated projection (rear cast projection on a specially coated glass screen).
Miz
After graduating from high school, she moved to Tokyo. Soon afterward, she was signed under "Universal Victor" and, under her real name, released "I WILL"(TX TV show "Renai Slot Kuru Kuru V" 's ending theme song), her first single. Five months later, she released a second single called "Ambition"(PlayStation game "Kouklo Theatro" 's theme song). Neither single charted in the top 100 singles and she was not asked to release anything else after that. Both singles are now out of print in most Japanese CD stores. Mizrock wrote the lyrics to all four of the songs on these singles.
