Hatsune Miku (初音ミク?) is the titular character of Hatsune Miku: Project DIVA who has starred in every game in the series. She is based off the avatar of the voice-bank of the same name produced by Crypton Future Media and released for Vocaloid, a series of singing synthesizer software.
When wearing her default attire, she has turquoise pigtails and wears a silver tank top, a black skirt with turquoise edges, and thigh high black boots, resembling a futuristic school uniform. Her tie is also turquoise.
Her attire is based on her box art appearance on the Hatsune Miku Vocaloid 2 software packaging.
Hatsune Miku is the humanoid persona of a singing synthesiser software developed by Crypton Future Media. She uses Yahama Corporation's Vocaloid 2 and Vocaloid 3 vocals singing sythesising technologies. Her voice was provided by Saki Fujita. The name "Hatsune Miku" roughly translates into "The First Sound from the Future", representing her position as the first of Crypton's "Character Vocals" and also received the codename "CV01".
She was released on 31 August 2007 and since then, she became an instant success which owed to Vocaloid becoming a cultural popular hit in Japan.
