草薙素子
is a Japanese manga series written and illustrated by Masamune Shirow, which spawned the media franchise of the same name. It was first serialized in Kodansha's "seinen" manga magazine "Young Magazine Kaizokuban" from 1989 to 1991, under the subtitle of "The Ghost in the Shell", and was later published in one "tankōbon" volume. Set in the mid-21st-century, it tells the story of the fictional counter-cyberterrorist organization Public Security Section 9, led by protagonist Major Motoko Kusanagi. "Ghost in the Shell 2: Man-Machine Interface" was the sequel work which follows the story of Motoko after merging with the Puppeteer. The last volume, "Ghost in the Shell 1.5: Human-Error Processor", contains four separate cases.
