The No. 1 Division were spread apart because of the Terraformars. In the depths of a dark hole, the gong had rung on a battle of the Earth vs. Mars. On Mars's side, a weevil-based Terraformar and on Earth's side, was Onizuka Keiji! He had always lived a very simple life. In order to protect the island his mother loved, and to protect his precious new friends, Onizuka stands in the ring yet again. Thus begins the brutal and unrelenting battle of fists.

2620 AD. Humanity tried a terraforming project on Mars, which lead to super evolved roaches, as well as the Alien Engine virus, which has a 100% death rate. To break through this nightmare, a crew that had undergone a special surgery has been sent to Mars. Hizamaru Akari and Michelle K. Davis lead crew members with special powers to try to resolve both of these issues.

No. 4 Division gets to the main ship, but finds they've walked into a trap. The Chinese division has betrayed them, and wants the two post-surgery humans as experimental samples. The Chinese have brought weapons, which they use to slaughter the Terraformars by the hundreds.

The mighty rank 1, Joseph G. Newton, arrives to save Yaeko from the horde! He easily dispatches Bao and rescues Akari and Michelle. But will he be able to achieve his greatest objective... and win Michelle's heart?

The battle for the broadcast tower rages on as the civilian crew of No. 1 division infiltrates the control room. But the Terraformars are there two! If they make any noise the trained killers of No. 4 Division will hear them, so they're forced to continue their work in total silence as the killer cockroaches get every closer...

The heroic sacrifice of the civilian crew allows No.1 and No. 2 division to temporarily take back control of the communications tower. But the last member of the crew passes out before she can tell Earth about No. 4 division's betrayal. Is all hope lost, or is there another way?

So the crew have made it back to Earth, but the Terra Formars have too! Akari takes on a mission in Japan and things get heated up while Earth forces try to figure out how to stop the Cockroaches.
