Hatsune Miku (Japanese: 初音ミク), officially code-named CV01,is a Vocaloid software voicebank developed by Crypton Future Media and its official anthropomorphic mascot character, a 16-year-old girl with long, turquoise twintails. Miku's personification has been marketed as a virtual idol, and has performed at live virtual concerts onstage as an animated projection (rear-cast projection on a specially coated glass screen). The name of the character comes from merging the Japanese words for first (初, hatsu), sound (音, ne), and future (ミク, miku),thus meaning "the first sound of the future",which, along with her code name, refers to her position as the first of Crypton's "Character Vocal Series" (abbreviated "CV Series"), preceding Kagamine Rin/Len (code-named CV02) and Megurine Luka (code-named CV03). The number 01 can also be seen on her left shoulder in official artwork.
