Casshern Sins

Casshern and Friender arrive at a city that is surrounded by a lake, which is populated with robots who have already accepted death. Casshern meets a disabled robot, Margo, who considers himself as an artist and paints white colors around the city. However, the current leader of the robots is far from pleased with Margo's optimistic behavior, and considers his presence to be corrupting to his fellow robots who have accepted ruin.
