Doc Ido, a doctor and mechanic who lives and works in the harsh, post‑apocalyptic Scrapyard, discovers the miraculously preserved remains of a female cyborg in a junk heap. After reviving and rebuilding her, the preternaturally strong amnesiac Gally begins to forge a new life in a world where every day can bring a fight for survival. The story adapts the first two volumes of the Battle Angel Alita manga.
