Nana Gray
Nana Gray is one of the characters in Black★Rock Shooter THE GAME. She is set to be one of Black★Rock Shooter's allies and a main protagonist. She is considered to be Black★Rock Shooter's prototype. According to Gray's game trailer she has a very close relationship with BRS and sees herself as a "not failed but not successful" creation. Gray's weapon of choice is a longsword with two tooth-like peaks at the edge and a black and orange color scheme. Nana is one of the 22 2nd-generation combat clones born to combat the alien invasion. Unlike her 21 other sisters, she was born a day later on 7th July 2034 due to problems in equipment. She is voiced by Miyuki Sawashiro in PSP Game. (Source: Black★Rock Shooter Wikia)
