A forgotten cybernetic hero awakens with no memories and is thrust into a brutal conflict between humans, robots, and a rising new species--forcing him to confront the truth of his own creation as he fights to save two kidnapped children trapped deep below a dying wasteland. He was forgotten for fifty years. Now he's the only one who can save them. When two girls vanish into a deadly mine run by rogue machines, a dying old man awakens Casshan--a lost cybernetic hero with no memory and a human heart buried inside metal. But underground lies more than hostages: a hidden robot refuge, a radical new species, and the truth about Casshan's own creation. Caught between humans, robots, and a new species called Neoroiders, Casshan must confront the past he's forgotten before the world destroys itself again!
