Following the closure of the Laughing Man case, Section 9 is re-established by Japan's newly elected Prime Minister, Youko Kayabuki, to combat the persistent threat of cyber-terrorism. A group calling themselves The Individual Eleven has begun committing acts of terror across Japan. While Motoko Kusanagi, Daisuke Aramaki, Batou, and the other members of Section 9 investigate this new menace, the Japanese government faces a separate crisis, as foreign refugees displaced by the Third World War seek asylum in Japan. But as the members of the special-ops team continually encounter Gouda Kazundo—a leading member of the Cabinet Intelligence Service—in their hunt, they begin to suspect that he may be involved, and that the events of the refugee crisis and The Individual Eleven may be more connected than they realize...

In the not so distant future, mankind has advanced to a state where complete body transplants from flesh to machine is possible. This allows for great increases in both physical and cybernetic prowess and blurring the lines between the two worlds. However, criminals can also make full use of such technology, leading to new and sometimes, very dangerous crimes. In response to such innovative new methods, the Japanese Government has established Section 9, an independently operating police unit which deals with such highly sensitive crimes. Led by Daisuke Aramaki and Motoko Kusanagi, Section 9 deals with such crimes over the entire social spectrum, usually with success. However, when faced with a new A level hacker nicknamed The Laughing Man, the team is thrown into a dangerous cat and mouse game, following the hacker's trail as it leaves its mark on Japan.

Austral Island is located 2,000 km south from Samoa islands. The existence of the island was removed from the official records, and Tagami Yuu made a journey to search for the reason. He sailed for the island with Dr. Waive who was his father's friend, Doris who is the daughter of Dr. Waive, and Captain who is the friend of Dr. Waive. On their way to the island, GAIL, the international conglomerate, and gangster, Cougar Connection lead by Lady Lynx attacked them. They managed to arrive at the island, but suddenly a mysterious monster began to attack them. When they became ready for death, a blue giant robot appeared. It destroyed the monster and saved them. Although it was an existence far beyond human knowledge, it reminded Yuu of something warm and familiar. It was Giant Gorg which is called Messenger of the God by the inhabitants of the island. Escaping from the attack of GAIL's assault team, Gorg guided Yuu into the underworld. There, he found alien's relic and an alien who woke up after 30,000 years' sleep. (Source: AnimeNfo)
