In a futuristic society, a 15-year-old prostitute named Rune Balot is rescued after being nearly killed. She is subconsciously given the choice to continue living due to an emergency ordinance to preserve life called Mardock Scramble 09.

He is part of the powerful October corporation that is stealthily conducting illegal activities.—ANN
