Shinya Kogami transitions from Inspector and Enforcer in Japan's Public Safety Bureau to a Southeast Asia and Tibet-Himalaya mercenary after leaving Japan. His exile period, depicted in *Psycho-Pass: Sinners of the System Case.3 – On the Other Side of Love and Hate*, involves rescuing refugees from guerrillas, including Tenzing Wangchuk. Tenzing seeks combat training to avenge her parents' deaths; Kogami mentors her while cautioning against revenge, drawing from his own vengeful past that caused his exile. His protective instincts persist despite operating outside legal frameworks. Frederica Hanashiro, a Japanese Ministry of Foreign Affairs agent investigating stranded citizens (*kimin*), aids Kogami in safeguarding refugees. This alliance provokes a clash with Garcia's mercenary group. Wounded in the conflict, Kogami is rescued by Garcia—who then exposes his betrayal by undermining peace talks. When Garcia critically injures Tenzing during her revenge attempt, Kogami intervenes, confronting and killing Garcia aboard an armored train to neutralize the threat. Post-conflict, Kogami joins Hanashiro's Suppressing Action Department (SAD) as a Special Investigator, returning to Japan under her command. Kogami's SAD role and Japan return, detailed in *Psycho-Pass Providence*, involve joint operations with the Public Safety Bureau against the paramilitary Peacebreakers. This reunites him with former colleagues Inspector Akane Tsunemori and Enforcer Nobuchika Ginoza. Tasked with recovering the conflict-manipulating "Stronskaya Papers," Kogami battles Peacebreaker operative Kai. Despite being overpowered, he deciphers clues from Kai (exposed as undercover agent Akira Ignatov) to locate the Peacebreakers' base. Later, he assists Tsunemori in raiding their island stronghold, shooting leader Tonami to protect her. This phase signals a shift in Kogami’s path. Mentoring Tenzing and partnering with Hanashiro distance him from the solitary vengeance that drove his pursuit of Shogo Makishima. Returning to Japan and collaborating with former adversaries like the Sibyl System—albeit under the Foreign Ministry—reflects a pragmatic turn toward institutional justice, though he remains wary of Sibyl's authority. Kogami’s background informs these events. Once a top Inspector in Division 01, his Crime Coefficient rose after trauma from colleague Mitsuru Sasayama’s murder during the "Specimen Case," demoting him to Enforcer. His fixation on avenging Sasayama by killing Makishima defied Sibyl, forcing his flight from Japan. Exile included mercenary work in zones like Shambala Float before reaching the Himalayas. He graduated first in his class from the Nitto School of Social Sciences, with a career spanning Inspector, Enforcer, mercenary, and Special Investigator. Key relationships shape Kogami’s choices. His bond with Akane Tsunemori evolves from collegial to mutual respect; she embodies ideals he once upheld. Before departing Japan, he left her a letter regretting broken promises but affirming the law’s failure to protect. Their reunion involves professional collaboration and tacit understanding, culminating in his resolve to free her after Sibyl imprisons her. His complex friendship with Nobuchika Ginoza, rooted in high school, withstands divergent careers and past clashes, stabilizing into a strained yet functional partnership.
