Heart of Iron is the seventeenth episode of Psycho-Pass.


After Makishima is taken in and the riots are brought under control, Kogami remains curious about how Makishima will be judged, as well as the whereabouts of Kagari. Later that day, Kasei tells Ginoza that Makishima's case has been taken out of the MWPSB's hands and orders him to investigate Kagari's whereabouts, much to the ire of both Ginoza and Kogami. Later, Makishima is confronted by Kasei who reveals herself as Kozaburo Toma who shares a cybernetic body with Kasei. He explains to Makishima about the true nature of the Sibyl System, which is revealed to be a supercomputer network composed of the excised brains of criminally asymptomatic individuals like himself. Toma offers Makishima to become a part of the System but he refuses. Instead, he kills Toma and escapes from the transit on its way to the Ministry of Welfare, briefly contacting Kogami about his escape before going silent.
