No. 49: Jack van John – Hottest Cosplay Girls

You might be familiar with Meiko's more prominent associate, Hatsune Miku. These virtual idols are what are known as Vocaloids and started out as software that could allow users to create songs using voice samples.

Jack van Johnson (despite the name, she's a girl), is shown here as an older version of Sakine Meiko, one such Vocalid, who appeared in the Project Diva game for PSP.
