Chuan Han rose to power as chairman of the Southeast Asian Union (SEAUn), a superstate forged amid global upheaval. A former military officer, he achieved the presidency but clashed with proponents of the Sibyl System, denouncing its integration as incompatible with democratic principles. His defiance triggered a covert operation by Colonel Nicholas Wong and mercenary Desmond Rutaganda, who assassinated him on Sibyl’s orders. The system replaced Han with a criminally asymptomatic proxy, engineered to advance Sibyl’s expansionist agenda while masquerading as the legitimate leader. Posing as Han, the double enforced Sibyl’s policies in Shambala Float, stratifying citizens via Psycho-Pass metrics. Latent criminals endured state-enforced servitude under omnipresent monitoring, cementing a militarized regime framed as essential for societal order. Inspector Akane Tsunemori exposed the deception during a corruption probe, verifying the double’s identity when a Dominator registered its Crime Coefficient at zero—a hallmark of Sibyl’s control. Compelled by Akane’s evidence, the impostor announced a resignation to facilitate democratic elections, though post-credits revelations showed Sibyl rigging the vote to retain power through the puppet leader. Archival records corroborated Han’s tenure in the SEAUn Military Police Corps, with photographs validating his pre-assassination career. His resistance to Sibyl originated from apprehensions about its authoritarian mechanisms, though specific ideological tenets remain absent from documented sources. The proxy’s rule perpetuated an illusion of continuity, obscuring systemic subjugation beneath rhetoric of public safety.
