In a dump in the lawless settlement of Scrapyard, far beneath the mysterious space city of Zalem, disgraced cyber-doctor Daisuke Ido makes a strange find: the detached head of a cyborg woman who has lost all her memories. He names her Alita and equips her with a powerful new body, the Berserker. While Alita remembers no details of her former life, a moment of desperation reawakens in her nerves the legendary school of martial arts known as Panzer Kunst... As Alita starts her life as a TUNED agent with new powers, she travels the desert, is reunited with Koyomi, meets eccentric blind psychometrist Kaos, and finally comes in contact with the terrifying leader of Barkjack, Den.
