Found in the scrapyard below the floating city Tiphares by the Hunter Warrior Daisuke Ido, Gally soon becomes a Hunter Warrior herself, hunting for bounties throughout the scrapyard city. Having no recollection of her past, Gally's only link to her memories is her "Panzer Kunst" a martial art style for cyborgs that she somehow remembers. While trying to live her life and protect those dear to her, she is eventually caught up in the struggle between the utopian society of Tiphares and the suppressed surface dwellers.
