In 2026, the world has entered the "hyper-scale era," a golden age of rapid economic and population growth driven by Patrick Castle’s mega-corporation, Nautlix. Through breakthroughs in AI, nuclear fusion, and terraforming, the global population has surged past 16 billion, forcing cities to transform into soaring megalopolises. Japan’s economy has skyrocketed to 34.74 trillion dollars, balancing this immense population pressure with advanced seismic skyscrapers.

Amidst these monumental global shifts, the profound changes hit close to home for a young couple in Tokyo. While watching a televised address by Prime Minister Morishita regarding Japan's futuristic urban planning, 23-year-old Fumiko decides it is time to step away from the politics. Craving kebabs, a trendy street food in the shifting metropolis, she suggests a nostalgic date at Tokyo Tower to watch the fireworks. As they head out into the vibrant night, the couple realizes they are living right in the pulsing center of humanity's bold new future.
