The 100 Hottest Cosplay Girls list begins with an oldie, but a goodie. Take a gander at Taki, the ninja extraordinaire from the Soul Calibur series. She's famous for her acrobatics, her deadly ninjutsu skills and... well, her ridiculous bust.
This is MissSinisterCosplay, from the US, in Taki's default costume. We're not sure how aerodynamic the suit can really be, but we appreciate its other features.
