In a far‑future era, Japan"s metropolises are sealed off from each other. Travel and migration are tightly regulated—often impossible. Each zone is governed by an AI overseer that shapes its realm as it sees fit. These enclaves converge into a single ideal, with every resident performing their duty to uphold the overseer"s design. Yet not all are content with the limited outlook of the city into which they were born, so some seek covert assistance to move to a more suitable cluster.
By day Equa, Ferres and Martese are typical high‑school pupils; at night they become Extractors—individuals who smuggle people across city borders illegally. Transporting those daring enough to abandon everything, Equa and her companions risk their lives to grant clients a fresh start. The peril of extraction escalates as the cluster overseers grow increasingly aware of the group"s deeds, which threaten their flawless utopias. Their operations are conducted under the cover of night, using hidden tunnels and encrypted communication. Meanwhile, AI moderators monitor anomalies, tightening security protocols to prevent leaks.
