Prima

In January 14, 2008 Zero-G release it’s first Vocaloid 2 product, Prima. What made Prima different from the rest of the Vocaloids before her was that her voice was model after a professional soprano opera singer. Which meant she could hit high notes with accuracy and ease. And though she was meant for opera, with a few adjustments Prima voice could also be suited for pop and R&B.

History
When Prima was release to Japan in February 22, 2008, she was often use as a back up singer for Japanese Vocaloid songs. Later on Prima was to be the first English Vocaloid to be included in the Lipync model series.

Fan Depiction
The LipSync model portrayed Prima as a extremely pale girl wearing a a dark red dress, and a white flower in her short, wavy, black hair.Another well known images features Prima in a white trench coat, a skirt with stockings underneath, and a top hat to complete the look.

Prima was given a yandere type personality by the Western fandom due to the fact that when people tried to illegally download vocaloids, such as Miku and Len/Rin Kagamine, they had to download Prima to get the program in English. However illegal downloads of Prima don’t have proper confirmations codes. Causing not only Prima to stop working but other Vocaloid programs as well. Basically if you couldn’t keep her you couldn’t keep any vocaloids.

It is said the Prima’s item is Wine, but because of her yandere nature it’s mostly likely you’ll see fanart of her holding weapons rather than the alcoholic beverage.
