In the forgotten wasteland of Rusty Bone No. 7, Orphan Jiang Shuci survived by scavenging until a transport ship crashed and changed his fate. He accidentally awakened a self-aware mini mecha "Iron Pimple" and gained the ability to resonate with its soul. Facing predators, black market thugs, and Imperial pursuers, he fights his way through with ruthlessness and agility. From a lonely snake in the wasteland to a dark harbor fighter, he took this "Stupid Thief" mecha that had been stolen from the Empire's armory and struggled to survive in the chaotic world of the shattered galaxy. He vowed to uncover the secret of the ancient rune chip and make his own name in this cannibalistic world.
