Casshern Sins : Season 1

In the near future, an amnesiac Casshern fights anti-human robots on a desolate Earth. Most of the humans were killed in an apocalyptic war when he was serving under the direction of Braiking Boss after he assassinated a girl named Luna.

Casshern meets up with a robotic couple and their dog named Friender. He finds out that they reside with a total of 10 robots, seeking to live in peace until they die.

After leaving the town of robots, Casshern meets the first human being of his travels, a man called Akos. He is invited by Akos to travel along with him. Later, Casshern re-encounters Friender, who wants revenge on him for killing his owners.

Lyuze questions her original intentions for revenge against Casshern, and her current intentions for him. After going through a series of mind-bending scenarios, she realizes that she has fallen in love with Casshern. Lyuze decides that her way of continue living is to pursue the same goals as Casshern, and stick with him as long as her life lasts.

Upon reaching Luna's castle, Casshern and Lyuze are attacked by two robots named Castor and Helene.
