Terra Formars, Vol. 12

Humanity's attempt to terraform and colonize Mars goes horribly wrong.

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...

Countless swarms of Terraformars close in on Shokichi and the others as they try to rejoin Akari's group. The struggle for survival looks grim as one disappointment and setback follows another. Reinforcements from China are arriving on Mars, but is their mission objective to rescue or to exterminate?
