Casshern Sins

Casshern escorts a robot singer named Janice, who wants to travel to a dilapidated city known as the Bazaar in order to sing to robot refugees who had been hiding there from the ruin of the outside world. Standing in their way are robots who believe that hope should die in a world full of ruin and, once they reach the Bazaar, will massacre everyone in sight. Once Casshern and Janice finally reached their destination, it is discovered that she is also at the brink of ruin, so she dedicates one final song to Casshern while he defends her and her audience from a horde of murderous robots outside.
