Miki (or "SF-A2 miki") is a Vocaloid2 announced by HEARTFAST, created by AH-Software and voiced by Furukawa Miki. She has long red hair with a funky ahoge, red eyes and doll joints.
Her standard outfit consists of a furry blue headset with pink microphone, blue gloves and a sort of futuristic-looking one-piece mini-dress, striped socks (kneehighs), and boots. Unlike the other Vocaloids, whose nature is somewhat ambiguous, Miki looks clearly robotic, with seam lines along her arms and legs and clear mechanical joints.
