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...

Shocked by the actions of the Terraformars hiding on Earth, Akari and the members of Ichi Security are more determined than ever to root them out. Tracking down leads points them to an unexpected hideout and the true identity of the enemy mastermind. The forces opposing them now may be more than they can handle on their own...
