As footage of the helmet killings appear on the internet, the helmets are distributed to more criminals who begin committing more horrendous crimes out in the open, prompting bloodthirsty revenge from the public in the name of self-defense. As the MWSPB are sent in to suppress the riots, Kogami deduces that the riots are intended to draw the police away from the Health and Welfare Ministry's Nona Tower facility, where the Sibyl System is located. As Makishima and his gang break in, Kogami, Akane and Shuusei head to the scene.

The Sibyl System reveals itself to Akane and notes that she understands the necessity of the system, if not its justifiability. Makishima finds the professor who is responsible for the hyper-oats and murders him after finding the information he seeks, taking along the man's fingers and eyeballs as a measure against biometric security. Kogami arrives on the scene not long after and leaves a clue for the MWSPB in the man's airpipe. Meanwhile, Akane makes a deal with Sibyl: if the System withdraws the execution order for Kogami, she will capture Makishima alive. Thanks to her detective work, they quickly find Kogami's clue and understand what Makishima's up to.
