Casshern Sins

The Flower That Blooms in the Valley of Ruin (1x9)

:

Casshern battles a horde of robots and was pushed off a cliff then fell into a hole in the ground. There, he finds a little mentally depleted robot girl who tends to his wounds and gave him flowers. It is revealed with the arrival of Ringo, Ohji and Lyuze that the place was in fact a graveyard for robots. The girl's name was Nico and used to be the servant of Luna. Not long after, robots which survived the fall starts to attack. As Casshern and Lyuze fights them off, Nico was unfortunately killed during the raid protecting a doll made of scraps which she still perceives to be Luna. Following the last words of the robot name Bolton, Casshern and the crew now travels the land to find Luna who hopefully is still alive to undo the ruination.
