In the late 26th century, overpopulation on Earth is reaching the breaking point, and humanity must find new frontiers. The terraforming of Mars has taken centuries but is now complete. The colonization of Mars by humanity is an epoch-making event, but an unintended side effect of the terraforming process unleashes a horror no one could ever have imagined... A giant swarm of Terraformars is bearing down on the escape vehicle where Bao from Division 4 is holding Akari and the others captive. Virtually defenseless, Bao contemplates a horrific course of action. Meanwhile, Marcos and his team head underground with a plan to hack into the Annex's communications array and attempt to contact Earth. But Bao's treachery and his unique ability may be the end of them all, if the Terraformars don't kill them first!
