SLAVE.V-V-R is a male VOCALOID producer. He made his debut on December 2014 with the song "やめろ！聴くな！(Yamero! Kiku na!)", which became his first work to enter the Hall of Fame. To many people's surprise, he had already announced his "retirement" on his debut work, though had still released more songs later on stating the same news. Thus, it has now become a habit of him to jokingly label every of his work as a "retirement song".
He mainly uses Yuzuki Yukari, occasionally SF-A2 miki, Nekomura Iroha and a few of other vocals recently. His most notable works are "お前がメシにありつくなど56876423年早いわ (Omae ga Meshi ni Aritsuku Nado 56876423-nen Hayai wa)", "このピアノでお前を8759632145回ぶん殴る (Kono Piano de Omae o 8759632145kai Bunnaguru)", and "追跡！家出少女の実態！(Tsuiseki! Iede Shoujo no Jittai!)", all have exceeded 800,000 views on their YouTube uploads.
