Members of Section 9 seek out a man named Philip Kukushkin, a Russian national who seems to know a lot about the creation of posthumans.

US special operations forces join the Section 9 team in their fight against a relentless posthuman named Suzuka Mizukane.

While extracting information from Kukushkin, the Section 9 team uncovers some shocking information about an AI program developed by the US government.

Togusa finally realizes that he's been trapped in his own memories — and suddenly finds himself in a devastated Tokyo in the year 2045.

After hearing from Togusa, Batou and the others head to Tokyo. Back in Fukuoka, the Major learns that a posthuman has hijacked a nuclear submarine.

Resurrected as a full-body prosthetic cyborg, Purin tries to hitchhike her way to Tokyo. US special operations forces face Mizukane's wrath.

Batou and the group get an update on the posthuman situation from Standard. The Major and Purin join the rest of the crew in Tokyo.

To take back control of the hijacked nuclear submarine, the Section 9 team targets Mizukane and Takashi Shimamura.

Shimamura wakes up and makes a desperate move, putting Kusanagi and her crew in an impossible position.

Kusanagi and her team do everything they can to stop the US from implementing their draconian plan to end the nuclear standoff with "N."

The Section 9 crew start living their regular lives as if nothing ever happened — and the only one who finds it strange is Kusanagi.
