She met Ryu Hayabusa while on a crusade to slay her own twin sister, whose fiend blood had corrupted her human side. With Hayabusa's aid, she was able to accomplish her heartbreaking goal and the two have been close friends ever since. Since birth, Rachel and her twin sister Alma have been afflicted with a blood curse that turns humans into fiends. By the events of Ninja Gaiden, the curse has consumed Alma. Believing there is no cure for their condition, Rachel sought out Alma through much of Ninja Gaiden in order to kill her to redeem her soul. Rachel's life's purpose is to eradicate fiends. As a half-fiend herself, her beauty belies a dangerous strength. She participated in the Dead or Alive World Combat Championships as an excuse to hone her fiend hunting abilities without the risk of killing her opponents. Upon meeting you and learning that you share her curse she has decided to train you in the art of Counter Fiend Combat as her successor.
