Ghost in the Shell 1.5: Human-Error Processor presents for the first time in America the "lost" Ghost in the Shell stories, created by Shirow Masamune after completing work on the original Ghost in the Shell manga and prior to his tour-de-force, Ghost in the Shell 2: Man-Machine Interface, but never collected before now.

Deep into the 21st century, the line between man and machine has been inexorably blurred as humans rely on the enhancement of mechanical implants and robots are upgraded with human tissue. In this rapidly converging technoscape, the covert-ops agents of Section 9 are charged to track and crack the most dangerous terrorists, cybercriminals, and ghost hackers the digital future has to offer. Whether dealing with remote-controlled corpses, lethally malfunctioning micromachines, or cop-killer cyborgs, Section 9 is determined to serve and protect... and reboot some cybercrook ass!
