Casshern Sins

That's good then... I was having the impression that they simply had no spare parts to repair the robots.

But who knows, nothing you said there disproves that the main problem is the lack of resources. The reason they might not accept new parts is because they are rusty to begin with. They can't build new robots, well maybe because they don't have the resources to do so.

Or this can be just a case of the "chicken and the egg" dilemma. I'm not buying the spiritual energy or souls explanation at this moment in time. I'll deal with that when the time comes. For now, these robots are simply dilusional.

Along the same lines, the little girl in the first episode said she was repaired by the old guy if not mistaken...
