Casshan Vol. 1

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!
