When Alita awakens with no memory of who she is in a future world she does not recognize, she is taken in by Ido, a compassionate doctor who realizes that somewhere in this abandoned cyborg shell is the heart and soul of a young woman with an extraordinary past. As Alita learns to navigate her new life and the treacherous streets of Iron City, Ido tries to shield her from her mysterious history while her street-smart new friend Hugo offers instead to help trigger her memories. But it is only when the deadly and corrupt forces that run the city come after Alita that she discovers a clue to her past - she has unique fighting abilities that those in power will stop at nothing to control. If she can stay out of their grasp, she could be the key to saving her friends, her family and the world she's grown to love.
A Hunter Warrior and cyborg healer named Ido formerly lived in the floating land of Zalem, the paradise that hovers above 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 Gally. Though possessing the body of a young woman, Gally now embodies Ido's most sophisticated and lethal cybernetic skills. The preternaturally strong, amnesiac Gally begins to forge a life for herself in a world where every day is a struggle for survival. Based on the first two volumes of the manga.
