Kamui Gakupo (EntityTopic, 12)
From Compile Worlds
Kamui Gakupo is one of the most underrated Vocaloids. Many people consider him an inferior Kaito when that isn't really the case at all. In the right hands Gakupo is an amazing rich voice that sounds even better than the man who provided it Japanese superstar Gackt.
Gakupo can't decided if he is a samurai or a gambler or a samurai subbing gambler. His sword supposedly is the key to his singing powers so if you wanna be as awesome as Gakupo just steal his katana.
If this hasn't convinced you yet that Gakupo is an epic vocaloid then you need to go listen to Dancing☆Samurai again. Not convinced? Well... there's the fact that the one who voiced him is a 496-year-old vampire Gackt.
