Nationality/Race: Vampire (presumably of Eastern European/French/African descent). Relatives: Kaz has a younger sister named Remi (Remiel). Her voicebank is currently in production. History / Robert Yorune: Kaz is a major revamp (haha vampire joke) of mugi's older UTAU "Robert Yorune". Mugi had decided that, while the original voice type had potential, the overall theme of a "ninja with a dark past" was too trite and stupid. So, he turned Robert into a vampire, and gave him a much better design. Robert Yorune has since been re-classified as a joke UTAU considering his poor quality.
