A world war breaks out on a planet over a newly discovered substance called oreikhalkos which can produce tremendous energy. Civilisation is destroyed by weapons of mass destruction, causing catastrophic environmental devastation. The human race lives in poverty under the control of the New Clones, humanoid chimeric weapons which have been developed using the oreikhalkos. As hybrids which combine physical performance with life force, they significantly alter the course of the war. Meanwhile, in a quest for the secret of his birth, Kaito (Emoto Tasuku), a member of the resistance and a chivalrous thief who steals supplies which he then distributes to the labourers, sets his sights on Eden with five buddies.
