Shout Out / Psycho-Pass: Sinners of the System

• The Sinners of the System trilogy has several references to Ghost in the Shell: Stand Alone Complex:
  • Case 1 involves a secret mining operation at a former disaster site digging up radioactive materials.
  • Case 2's climax deals with a plot point involving Kyushu Island, a district called "Dejima," and a nuclear submarine.
  • Case 3 has a not-very-subtle reference to the first season finale when Frederica destroys an enemy drone by repeatedly shooting it at point blank range with a bolt-action anti-materiel rifle.
