After Marin Kitagawa introduced Wakana Gojou to the world of cosplay, he has been creating her outfits with ease. Even so, he still has a lot to learn, and every new lesson seems to strengthen his love for sewing and for the hina dolls his grandfather taught him to make.

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.
