She killed her abusive parents when she was 8, and was taken in by a man, who became her mentor when she was 10. She became a Master Kunoichi at the age of 15. She will speak Japanese if she is talking to herself. She follows a creed of honor: "If I fail, I shall lose my honor, and with it my dignity. I will reward the one who beats me by marrying them."
