The Last Contract of Isako draws heavily from the cyberpunk genre, particularly its tradition of the “corporate samurai.” Emerging in the 1980s with foundational texts like William Gibson’s Neuromancer (1984), cyberpunk often features dystopian futures dominated by powerful mega-corporations where technology has saturated daily life. In Gibson’s novel, a decaying dynasty that controls an orbital habitat sets the template for the omnipotent corporation as both employer and antagonist. Similarly, Bruce Sterling’s Islands in the Net (1988) and Pat Cadigan’s Synners (1991) similarly imagine worlds where corporate infrastructure has supplanted the nation-state. More recent works like Richard K. Morgan’s Altered Carbon (2002) and Malka Older’s Infomocracy (2016) extend the tradition into questions of embodiment and governance. 

In Lee’s novel, the Starhome Exploration Group is a classic example of the singular dystopian entity that governs every aspect of society on Aquilo, from resource allocation to employment and even end-of-life decisions. The novel protagonist, Isako, functions in her corporate role as an “atier,” an elite contractor who blends swordplay with business acumen. Within this framework, Isako embodies the corporate-samurai archetype: a highly skilled mercenary operating within a hyper-capitalist system, bound by a strict personal or professional code. Isako’s character finds mirrors in works like Neal Stephenson’s Snow Crash (1992), where the protagonist is a freelance hacker and master swordsman navigating a world fractured by corporate entities. Likewise, the video game Cyberpunk 2077 features a “corpo” archetype that directly dramatizes the tension between contractual loyalty and personal survival. 

The novel also reinterprets the concept of the rōnin, or masterless samurai, a figure popularized in the films of Japanese director Akira Kurosawa. In movies like Yojimbo, a lone, cynical warrior navigates a corrupt world, selling his skills while adhering to his own moral compass. Kurosawa’s Sanjuro and Seven Samurai similarly explore the moral ambiguity of warriors displaced from feudal service, while Kazuo Koike’s manga Lone Wolf and Cub extends the archetype into a meditation on vengeance and inherited duty. Western science fiction has repeatedly translated these figures into futuristic idioms: Joss Whedon’s Firefly recasts the defeated soldier as an interstellar smuggler with a private code, and Ken Liu’s The Grace of Kings (2015) draws on East Asian martial traditions to interrogate loyalty and rebellion. 

Lee adapts this archetype for a science-fiction setting, with the contractors’ Code of Client Service acting as a futuristic version of the samurai’s Bushido. When Isako’s client resigns, she explicitly becomes a “ronin,” a masterless swordswoman forced to navigate the treacherous politics of the Company on her own terms. By blending the aesthetics of cyberpunk with the honor-bound ethos of the samurai, the novel fleshes out a complex protagonist caught between corporate duty and personal integrity.
