Vocaloid
Originally, Hiroyuki Ito—President of Crypton Future Media—claimed that Hatsune Miku was not a virtual idol but a kind of the Virtual Studio Technology instrument. However, Hatsune Miku performed her first "live" concert like a virtual idol on a projection screen during Animelo Summer Live at the Saitama Super Arena on August 22, 2009. At the "MikuFes '09 (Summer)" event on August 31, 2009, her image was screened by rear projection on a mostly-transparent screen. Miku also performed her first overseas live concert on November 21, 2009, during Anime Festival Asia (AFA) in Singapore. On March 9, 2010, Miku's first solo live performance titled "Miku no Hi Kanshasai 39's Giving Day" was opened at the Zepp Tokyo in Odaiba, Tokyo. The tour was run as part of promotions for Sega's "Hatsune Miku: Project Diva" video game in March 2010. The success and possibility of these tours is owed to the popularity of Hatsune Miku and so far Crypton is the only studio to have established a world tour of their Vocaloids.
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.
