Iku, a gynoid designated Oripha/E-19 developed based on the female human form, fights on the warfront, cutting through countless soldiers with her sharp blade amid the battle between the Human Army and the Salvation Army. Eventually, she is captured and brought defenseless before Orga, commander of the Human Army. Her combat programming and control unit are removed, leaving her powerless. Orga decides to use Iku as a sexual relief doll—a flesh puppet—for soldiers who have endured prolonged warfare and enforced abstinence. Her journey takes her into a new trial, one far different from the battlefield. [BAD END]
