The Ruined Angel

Casshern meets Sophita, a female robot who enjoys fighting and killing her own kind. She is dubbed "Angel of Ruin" by the robots who heard of her and feared by them. Sophita wants to fight Casshern, but the latter refuses. She tells him that fighting is her way of living, albeit in a twisted way. Unable to instigate him to fight, she leaves. A group of robots who heard of Casshern's reappearance ambushes Sophita to draw Casshern's attention. True enough, Casshern appears to rescue her, taking a blow from the robot leader. However, the robot leader does not want to kill Casshern any longer, now that he wants to live out his life without shortening it. In the aftermath, Sophita forces Casshern to fight her. Casshern then allows Sophita to run him through with his sword, making her realize she genuinely cares about him and finally stops fighting him. She leaves, telling Casshern that they will eventually meet again.
