In 2025, the Tokyo of the original film has been replaced by Zebra City, a totalitarian city-state ruled by a despotic governor who has rebranded the entire urban identity around monochrome stripes. The most striking feature of this future is Zebra Time, a mandated five-minute period occurring twice daily at 5:00 AM and 5:00 PM. During this window, all crime is legalized, allowing the state's Zebra Police to hunt and eliminate "unfit" citizens with total impunity, effectively gamifying state-sponsored cleansing.

The societal dynamic is a dark satire of modern Japanese idol culture and media obsession. The state maintains control not just through violence, but through the sensory overload of Zebra Queen, a pop diva who serves as the face of the regime's propaganda. This version of Earth—specifically Tokyo—is depicted as a clean, high-tech, yet morally bankrupt environment where the line between entertainment and execution has entirely blurred. The film implies that the rest of the world remains at risk of this "Zebra-fication" as the regime seeks to export its ideology via satellite.

Technologically, the film predicts a future where digital media and urban design are seamlessly integrated into a singular tool for social engineering. While the "Zebra Time" concept remains a hyperbolic allegory for the The Purge-style social release, the film’s depiction of full-body cyberscanning and the use of celebrity influencers to mask ultra-right-wing political shifts mirrors modern concerns regarding the intersection of entertainment and radicalization. Due to the film's niche status, few retrospective analyses exist that compare its specific technologies to real-world 2025 advancements, focusing instead on its socio-political commentary regarding the Happy Science movement and right-wing nationalism.
