Recently, there have been a number of incidents in which robot puppets killed their owners and then committed suicide. as the families of the victims were not prosecuted, and there were politicians and public security officials among the dead, Public Security Unit 9 sent a Bart team to investigate the case. The killer dolls are all Hadley models produced by the company in the desolate area. at the request of some customers, the model also has the function of heterosexual playmates. Bart started with the killing of the company's shipping officer in the desolate area and was involved in the battle with the gang. during that time, someone invaded his brain and made him self-harm. Bart decided to go straight to the headquarters in the desolate area. he and Togusa visited Kim, a hacker on Etorofu Island, who set a system trap, but luckily Suzi warned to prevent Togusa from falling into control. Relying on Kim's clue, Bart boarded the factory ship set up by the company at sea in the desolate area, and Suzi came to him again to fight side by side.
