before both girls were retrieved by Muster and Maruki. Later Muster's assistant Zoe revealed to the girls that Yoko was not genetically related to Princess Kagura and her real genetic mother was Muster's late sister Nollin. At some point Yoko joined the mercenary organization Grünthal alongside Erica and was trained in Panzer Kunst at Grünthal's Mauser School, although she might also have received training on techniques from the Schneider School and possibly the later extinct Gossen School. However, as teenagers the two childhood friends had a falling-out, which resulted in Yoko mortally wounding Erica during a sparring. As an intermediate Geselle level Künstler, Yoko was recruited into the Mauser School's covert op unit Kammer Gruppe, and earned the nickname "Yoko von der Rasierklinge" ("Razorblade Yoko") for her ferocious efficiency in combat. In ES 386 during the height of the interplanetary Terraforming War, the 16-year-old Yoko was picked to carry out Operation Maulwurf against the Venusian-Earth alliance, and managed to infiltrate Ketheres and upload a virus into the supercomputer Melchizedek. This disrupted the navigational systems of the five Leviathan-class colony ships, destroying four and killing 450,000 civilians, as well as causing a complete Gestalt breakdown in Melchizedek's organizational processes, from which it never fully recovered.

Due to special protocol built into her cyborg body, Yoko's brain survived atmospheric entry, but crash-landed near Star City where she lay in suspended animation for almost 200 years.

When Ido discovered that she was still alive, he took the cyborg girl back to his clinic to rebuild her. As she was an amnesiac, he named her after his recently deceased black tomcat, Alita. When the reconstructed Alita suspects Ido of murdering women to provide her body parts, her guilt caused her to stalk and confront Ido, only to discover that he is a hunter-warrior seeking the true killer. When protecting the injured Ido, her fighting caused an instinctive recollection of the lost Martian battle technique "Panzer Kunst", which allowed her to quickly deliver a single killing blow to the murderer. She decided
