Twelve were destroyed twenty years ago, and the horrifying age of darkness that fell upon the world has come to an end. The survivors gradually crawl out of their shelters. They dream of a hopeful future and are determined to rebuild society from scratch. But far away, in the dead megacity, something waits for them: Ziro. First Father of the Twelve. The torments that ruined his human life pursue him, and the hatred born from his rebirth burns brightly. His rage will subside only when he destroys Amy—the only hope of humanity, the Girl from Nowhere, who grew up ready to rise against him. In the last confrontation, light and darkness will collide, and at last Amy and her friends will learn their fate.
