Battle Angel Alita part 1

The story follows a Hunter Warrior and cyborg healer named Ido. Ido formerly lived in the floating land of Zalem, the paradise that hovers over the refuse heap of Scrap Iron City in which he now resides with his former lover, Chiren. In his travels as a bounty hunter — killing spine thieves in a world in which human nerve tissue has become the most precious commodity — Ido one day discovers and repairs the remnants of a cyborg whom he names Alita.
