Casshern Sins

Enter the world of Casshern Sins. A world where humans and robots once coexisted, now a wasteland where only the luckiest of humans have managed survived and even the immortal robots are degrading into rust. The cause of all of this - the apparent death of all materials, living or not - being attributed to something called "the ruin."

Casshern, our main character, has no memories of his past, except for telling someone called "Luna" he is going to kill her. Constantly assaulted by hordes of robots, claiming that if they take his head, they will "end the ruin." One thing he does know is that he is not affected by the ruin. His body is perfect, and any time he is wounded, it regenerates almost instantly. He also goes into a trance whenever his life is threatened, killing anyone and everything in his way.

It's hard to go into detail about this series without spoiling, but basically, Casshern goes on a quest to find his memories, figure out who he is, to find out why he's immortal, to try and stop his "killing trances," and to find out what he has to do with this "ruin" that is destroying the world.

Any fan of action, mystery, drama, and psychological stuff will probably enjoy this series, as there is quite a bit of it. I think it also has emphasis on respecting life, as Casshern travels around the decaying world and meeting people trying to survive, or trying to cope with the fact that their loved ones and even they are dying.

Personally, I consider this one of my top 10 favorite series.
