VY2, codenamed 勇馬 ("Yuuma"), is the second from the avatarless VY series of Vocaloids, produced by Bplats and like VY1 before it, VY2 is a Vocaloid without set gender, face or voice. Similar to VY1 being confirmed "Feminine", VY2 was confirmed to be a "masculine" voice type.
66 (Roro) (Male, Short hair, Pink Hair) is the wining entry of VesFes 2011. Despite Roro being commonly used as a avatar for VY2, he was never picked as a offical avatar of the software, though has been used as a concept in an illustration book to represent the vocal "VY2".
