Galaxy Express 999

The 999 travels to Pluto, where the frozen human bodies of the machine people have been laid to rest. Tetsuro meets Shadow, the machine woman who is caretaker of the graves. Shadow shows him her frozen human body, a body so beautiful that she refused to have a face on her machine body since it couldn't compare to her human face. Shadow tries to capture Tetsuro to regain her human body, but Maetel saves him.
