The year is 2035 on the planet Tinos, which was colonized by humans three centuries earlier. Due to cold arctic conditions covering most of the planet and an oxygen level at only half of Earth's concentration, inhabitants are compelled to wear life-support apparatuses to survive. In the criminal underworld of Junk City, the black market for these devices is a thriving enterprise. The protagonist, Blue, urgently requires a life-support system after being mugged. However, a group of unscrupulous criminals swindle him out of his money, leaving him with an obsolete model equipped with an old AI. Blue is manipulated by the police chief, Weiser, into committing murder, and is subsequently killed. The AI, named Fatso, chooses to save his life by transferring him into a new artificial body endowed with extraordinary strength and the combined knowledge of their three hundred and seventeen years. Resurrected, Blue resolves to seek revenge and protect those suffering under Weiser's tyranny.
