Hatsune Miku
Hatsune Miku was the first Vocaloid developed by Crypton Future Media after they handled the release of the Yamaha vocal Meiko and Kaito. The name of "Hatsune Miku" was conceived soon after the Vocaloid 2 announcements, when an English and Japanese vocal were developed for the character. The intended design was delayed and later used for Megurine Luka instead. Miku was intended to be the first of a series of Vocaloids called the ""Character Vocal Series"", which included Kagamine Rin/Len and Megurine Luka. Each had a particular concept and vocal direction.
Virtual band
The members of virtual groups are depicted as animated characters, with their own personality, voice, history, and playing style. For example, Alvin, the leader of the Chipmunks, is considered mischievous, and Skeleton Staff's Guitarist Stanton is a party-going underachiever, furthermore, Freen in Green's bassist Sparky is sluggish and has been described as egotistical and pretentious, while Murdoc of Gorillaz is a middle-aged satanic bass player. Another example is Hatsune Miku who does not have a definite personality; because her way of being depends on the fans, her personality changes in each song made by the users of Vocaloid.
