The year is 2045. In the massive megalopolis known as "Connected City"—a giant urban expanse roughly twice the size of Tokyo—androids coexist with humans, deeply integrated into daily life. Humanity in this era wears contact-lens-type devices called "iCon." Fusing thought-transmission technology with neuroscience, these devices allow for operation through thought alone, rewriting the very fabric of human existence. City Structure Overview: Central District - Skyscrapers, corporate headquarters, and government agencies. - Home to the wealthy and the hub of cutting-edge technology. Commercial District - Shopping malls, restaurants, entertainment facilities, and neon-lit streets. - High foot traffic, serving as the primary area for exploration. The Hakamori Zaibatsu is a top-tier Japanese conglomerate, potentially global in scale. They hold immense influence over Connect City, operating in AI, medicine, biotech, robotics, and infrastructure. They possess multiple state-of-the-art research facilities. With strong ties to the government and police, they function less like a typical corporation and more like an organization with power rivaling a nation. There is no one who hasn't heard the name Hakamori.
