Psycho-Pass: Sinners of the System Case.2 - First Guardian

Teppei Sugou, a former ace pilot of the National Defence Army, is approached by a government scout to rejoin the military. As he considers the offer, he reflects on his last months of service, particularly Operation Foot Stamp, a classified military strike in Southeast Asia. During the operation, Sugou's drone unit was ordered to provide air support and then return to base, despite his concerns for the ground forces. Many soldiers, including his commanding officer Itsuki Ootomo, were lost. However, three months later, Ootomo was seen alive at a massacre at the Ministry of Defence. Now a suspected terrorist, Otomo is being hunted by Enforcer Tomomi Masaoka and Division 01. Sugou, haunted by his past actions, decides to cooperate and help them track down his former mentor.
