*Ghost in the Shell 1.5: Human-Error Processor* presents 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 until now. Focusing on Section 9 agents in their daily battle against technocrime, Human-Error Processor has all the mind-twisting cybermadness you've come to expect from Ghost in the Shell but set in a more police-procedural context with action and suspense galore.
