High school student Wakana Gojou spends his days perfecting the art of making hina dolls, hoping to eventually reach his grandfather’s level of expertise. While his fellow teenagers busy themselves with pop culture, Gojou finds bliss in sewing clothes for his dolls. Nonetheless, he goes to great lengths to keep his unique hobby a secret, as he believes that he would be ridiculed were it revealed.
Enter Marin Kitagawa, an extraordinarily pretty girl whose confidence and poise are in stark contrast to Gojou’s meekness. It would defy common sense for the friendless Gojou to mix with the likes of Kitagawa, who is always surrounded by her peers. However, the unimaginable happens when Kitagawa discovers Gojou’s prowess with a sewing machine and brightly confesses to him about her own hobby: cosplay. Because her sewing skills are pitiable, she decides to enlist his help.
As Gojou and Kitagawa work together on one cosplay outfit after another, they cannot help but grow close—even though their lives are worlds apart.
The year is 2045, and artificial intelligence has undergone tremendous developments. Governments use them as weapons, engaging in never-ending warfare to sustain their economies. The mercenary group GHOST, headed by Major Motoko Kusanagi, is no stranger to this landscape. However, the rapid innovation of this technology causes a new threat to loom over the horizon.
Having left Public Security Section 9, Kusanagi and her group are involved in many operations worldwide related to these proxy wars. But a seemingly simple job of locating an arms dealer drags GHOST into a hidden conflict against cybernetically enhanced individuals, who have inexplicably gained extreme intelligence and physical abilities. Dubbed “post-humans,” their emergence sets off a chain of events leading to the reunion of Section 9. Armed with a new mission, it is up to Kusanagi and her reestablished team to prevent global chaos at the hands of these post-humans.
