Gally's decapitated head is found in the scrapyard below the floating city of Tiphares by the Hunter Warrior Daisuke Ido. Ido fixes her up, gives her a body and raises her as his own. Soon enough, Gally joins Ido as a Hunter Warrior, hunting bounties throughout the scrapyard city. She has no recollection of her past, and Gally's only link to her former self is her "Panzer Kunst," a cyborg martial art she somehow remembers. While trying to embrace her new life and protect those dear to her, Gally is eventually caught up in the struggle between the utopian society of Tiphares and the suppressed surface dwellers.
