By 2111, the solar system is colonized. The settled moons and planets are lawless, leaving the police powerless. To combat the evil within the solar system, Isaac Godonov forms J9, a team consisting of himself, Blaster Kid, Stephen Bowie, and Angel Omachi. They take on any missions the police refuse, using their robot Braiger... for a fee. Meanwhile, the Nubia section of Earth has a plan to destroy Jupiter to create 30 additional planets for human colonization. However, this plan will lead to the destruction of Earth.
