Anis Bright, a warrior of the Galactic Republic Army, teams up with the Liberation Army to defeat the anti-Republic Zoid forces invading the independent star system planet Mazu, securing victory. However, realizing the Republic's intent to colonize Mazu, Anis deserts the military and becomes a mercenary fighting for freedom and peace alongside the Zoids. One day, severely wounded in battle against the Zoids, Anis is captured and later rescued through a deal with the Republic Army. Faisal, her former commanding officer, returns to Mazu and asks for Anis's help to reclaim a pioneer colony destroyed by Zoid attacks. With assistance from Mazu's prince, Parnas, Anis infiltrates the Zoid army's secret base and defeats enemy after enemy. But when her powered suit runs out of energy, she's forced to continue fighting in her weaker nanosuit. With her combat strength drastically reduced, Anis faces the Brain Zoid—the controller of the Zoid forces—which overwhelms her. Vulnerable in her low-defense nanosuit, Anis is pushed to the brink of death by the Brain Zoid's relentless assault. Ultimately, Anis triumphs and seizes a new hope. [HAPPY END]
