SF-A2 miki

Etymology
Often shortened to just "SF-A2 miki", her codename of "miki" comes from her provider's name "Miki Furukawa". In Japanese, 'development code' or 'codename' translates as 'kaihatsu koudo'. The meaning of the "SF-A2" part of her name has never been stated.

Appearance
According to information that came from the 2012 redesign, miki was designed to look like she was made out of a inorganic material and was conceptualized as an android. Her body is designed to look like that of a child, but also give her the overall appearance of young female that is teenaged. Though she is an android, she is covered in muscles made from various materials such as carbon nanotubes, but were made loose to give a mild deformed look about them. Having an immature-looking body allowed more easily for her to be passed off as younger then she looks, similar to how Miku and Rin could do the same.

She, along with Kaai Yuki and Hiyama Kiyoteru were introduced to expand the VOCALOID market and give producers more choices. [2]

An album with her singing Christmas songs, "VOCALOIDS☆Ｘ‘MAS" was also set to be released in November, 2009. Notable VOCALOID song creators' works are included [3][4]. She was also used for the introduction to the Hello Kitty game, Hello Kitty to Issho! Block Crash 123! on its official page.
