Zuru, a little girl, embarks on a desperate quest for sustenance in a post-apocalyptic metropolis governed by machines. Things go wrong when her team accidentally activates the Safeguard, the city's AI protection mechanism. Her comrades are on the edge of annihilation after being attacked by the robots when a mysterious guy named Killy appears and exterminates the hostile units. Despite his heroism, Zuru remains skeptical of Killy and questions his motivations. He discloses that he came from hundreds of levels under the city in search of people with the Net Terminal Genes—a characteristic that would allow humanity to reclaim control of their society and shut down the Safeguard. Zuru and the others were moved by his narrative.
