By day, Sakura Morishita is a successful businesswoman, but in truth she is Justine, a warrior sworn to protect justice and love. Doctor Machinary, a high-ranking member of the evil organization Diablos, has been conducting a top-secret project to transform foot soldiers into cyborgs in order to defeat Justine. When the experiment succeeds, a new and terrifying enemy emerges to attack her. Enemies that she could once easily defeat now move in unnatural, unpredictable ways. Justine senses the change and realizes she is being specifically targeted—but it's too late. She is captured. Subjected to brutal torture, she is forcibly reverted to her human form, left completely powerless and at their mercy. Doctor Machinary stops the torment and allows her to temporarily escape. But that moment marks the beginning of a new and horrifying nightmare.
