The UFE forces gather in Earth's orbit at Trident Base, built into an asteroid, as they prepare for a large-scale operation against another asteroid base called Marineros owned by Vers. Meanwhile, Saazbaum rallies his own forces for a quick strike on Trident as they travel to Marineros Base. Slaine finds that Lemrina shut down the Tharsis' Aldnoah Drive, and tries to reason with her to get it running again. Eventually, Slaine gets her to restart the Tharsis. As Lemrina visits her still-unconscious sister and schemes to replace her position, the Martian forces begin their assault while the UFE dig in on nearby asteroids. Inaho makes use of his new cybernetic eye to accurately shoot down several enemies, but Slaine somehow manages to see the trajectories of the shells being fired at him in the Tharsis, and dodges at the last second. The Martian forces soon pass by the base as Inaho and Slaine confirm that they fought each other.
