Casshern Sins

Casshern: There’s only life here.
Luna: What’s wrong with that? You can life eternally.
Casshern: No. Even thought there’s life, no one is living. You’re letting life overflow like a spring, and everyone merely drinks from it. But Dio and the robots and humans weren’t like that. They were like flames, flames of life burning bright.
Luna: But flames will burn out one day.
Casshern: That’s why they were fierce and beautiful.
