That's Kanako Kondou, not the character per se, but the actress is lending her voice to the game. Once again.
Kondou already voices fighter Noel Vermillion as well as cyborg ν-13 and BlazBlue: Continuum Shift's cyborg Λ-11. In the console version, Kondou will be voicing new character μ-12.
She has the market cornered on BlazBlue cyborgs!
Continuum Shift will be released in Japan on the PS3 and the Xbox 360 this summer.
