In the aftermath of a devastating global war that decimated humanity, the city of Olympus stands as a beacon of hope and order. Governed by a sophisticated artificial intelligence known as Gaia, the city is inhabited by both natural humans and Bioroids—genetically engineered beings designed to maintain peace and manage the complexities of social harmony. Deunan Knute, a battle-hardened soldier who has spent years surviving in the lawless wastelands, is rescued and brought to this gleaming metropolis. Alongside her former lover and cyborg partner, Briareos Hecatonchires, she is thrust into an uneasy existence where the lines between humanity and artificiality blur.Deunan soon discovers that the stability of Olympus is fragile. A powerful faction within the human military, led by the ruthless General Uranus, views the Bioroids as an
existential threat to biological dominance. They believe that humanity’s autonomy is being stripped away by the calculated logic of the governing AI. As tensions escalate, a clandestine plot to initiate a "total reset" of the city’s systems emerges, threatening to wipe out the Bioroid population and potentially collapse the infrastructure that keeps the survivors alive.Motivated by a desire to protect the fragile peace she has finally found, Deunan joins the elite E.S.W.A.T. unit. Her journey becomes a desperate
race against time as she uncovers a conspiracy involving the "Appleseed"—a mysterious administrative program capable of granting Bioroids the ability to reproduce, an evolutionary leap that the human hardliners are determined to prevent at any cost. As the city descends into chaotic urban warfare, Deunan and Briareos must navigate shifting loyalties and ethical dilemmas. They are forced to question what truly defines a human soul: is it the biological vessel, or the capacity for empathy and sacrifice? In the climactic confrontation, Deunan faces the ultimate choice between preserving the status quo and securing a future where both humans and Bioroids can coexist as equals. The fate of the last remnants of civilization rests on her ability to bridge the widening chasm between two species, proving that even in a world built on cold logic, the human spirit remains the most potent, unpredictable force of all.
