* Case 1: Nobuchika Ginoza and Mika Shimotsuki investigate a prison in *Crime and Punishment*. * Case 2: *First Guardian* centers on the backstory of Tomomi Masaoka and Teppei Sugo. * Case 3: *On the Other Side of Love and Hate* follows Shinya Kogami's activities outside Japan. Kagari's character arc concludes in the first season of the main "Psycho-Pass" series, where he is killed investigating the Sibyl System's secret. His background and development are detailed in other media, including the main series and the novel "Chaser Shusei Kagari," which explores his early life in an isolation facility and initial experiences as an Enforcer. These events fall outside the "Sinners of the System" trilogy narrative.
