About 7 years ago I saw this anime movie about a young boy that lived in a futuristic dystopian city filled with trash. This boy was a mechanic and found an android girl that turned out to be a weapon of mass destruction. At the end of the movie this android girl sacrificed herself to save the boy.
That's about all that I remember and I've confirmed that it's not the following movies: "Battle Angel" and "Metropolis". If anyone has some insight on what the title of this movie could be, please do tell and I'll check it out.
