Two worlds at war. Two brothers at war. With advanced weaponry and impenetrable armor, the Crusaders smash aside anything that stands in their way. Led by Kaneda Kusanagi, they have only one mission: to destroy Matriarch, the last thinking machine, and free the people of Jupiter from her tyranny. Whether they like it or not. Standing in their way are the Dragons, led by Kaneda’s estranged brother Ryu. With super-human reflexes and invisible battle suits, the Dragons are masters of infiltration and sabotage. Loyal only to Matriarch, they will stop at nothing to protect their way of life. The two brothers are set to collide in a battle that will shake the great powers of the solar system and force both men to question what they believe in.
