Vane Lily
Vane (pronounced Vah-neh) is a California based musician, who primarily writes original songs using Vocaloid. They used to go by "Nessa" and "I0LITE" so you may recognize some of their works under those names.
They are the director of "Team 6x111" - who are described as "a group of musicians and artists who like to tell stories". The group's current project is "To Hell and Back", a Vocaloid song series about what happens after you die.
