銃夢
The futuristic dystopian world of "Battle Angel Alita" revolves around the city of Scrapyard (Kuzutetsu in the Japanese and various other versions), which has grown up around a massive scrap heap that rains down from Zalem. Ground dwellers have no access to Zalem and are forced to make a living in the sprawl below. Many are heavily modified by cybernetics to better cope with their hard life.
