The Isolated Zone: Shinku Chitai

"Z," a biological weapon developed in utmost secrecy, is unleashed following a massive earthquake that devastates the Kanto region. To contain the epidemic, the Japanese government decides to isolate the area, abandoning the few survivors to their grim fate. Tetsu was 12 years old when the disaster struck. Now, he leads a group of children whose survival is threatened in a region where the weakest are preyed upon by the strongest. But where did this disease come from? What is happening outside the exclusion zone, and why is no one coming to save them? The lack of resources and the loss of several friends will lead Tetsu on a quest for the truth.
