The Ground Investigation Bureau (火星王国議会派 Chijō Kansatsu Kyoku?) (G.I.B.), known in Japan as the Ground.Inspect.Bureau, was a Tipharean government agency responsible for safeguarding Tipharean interests on the surface, primarily beyond the Scrapyard in the Badlands. It did this through agents on the surface who were members of the elite force known as the TUNED. The G.I.B. later created the TUNED AR Series 2, a series of combat androids based on Alita, the original TUNED agent. The G.I.B. reached its high water mark during the climax of the Barjack War by destroying the Heng. However it was effectively dissolved when the secret of Tiphares was inadvertently discovered by its staff, who were terminated by the Medical Inspection Bureau.
