Len!
Japanese singer Gackt.
Kiato Vocaloid is a project featuring a virtual singer, and its primary voice is provided by a Vocaloid software, rather than a human singer. The character associated with Kiato is often represented visually, but the actual singing is generated through Vocaloid technology, which allows for the synthesis of human-like singing voices. Various producers may contribute to the creation of songs using this Vocaloid.
The original singer for the Servant of Evil is Kagamine Len with Kagamine Rin providing backup vocals.
Every VOCALOIDs have diffrent prices. The cheapest VOCALOID is currently $40 dollars and the highest price is about $400. You can buy the VOCALOIDs in their company's website.
No, Hatsune Miku is not an anime. Hatsune Miku is a vocaliod. A vocaliod is a computer generated singer, but Hatsune Miku is by FAR the most popular in Japan.
Yes, Ai is a vocaloid. A vocaloid 3 to be exact.
Vocaloid fans like Vocaloid. Vocaloid fans are located around the world. Vocaloid fans also have a tendency to like Japanese animation (anime) and comics (manga).
Piko is the name of both the Vocaloid and the voice provider, who is naturally not a Vocaloid.
Lia, a famous Japanese singer. She's the one who sang the Angel Beats! opening and something for AIR, I forget what.
No Teto is not a Vocaloid. I have heard before that She was made to be a prank. She is mistaken to be a Vocaloid. She sounds like a Vocaloid(y) software.
