Story

Outside, a Rebel soldier informs Katalina and Kriemhild that the Martians are attacking their base and pushing them back due to their latest weapons. Kriemhild prepares to mobilize; Katalina notes that she has a strong sense of duty, yet it always puts her in danger. Kriemhild defends herself stating that if ACE was not available during a critical situation, no one would defend them. The soldier then informs the two that as the enemy positions are not known, the soldiers are taking an unfavorable defensive line. Katalina remarks about the Martian's technological capabilities and wonders why the Professor had left them. Kriemhild states that she could try to pinpoint the enemies from the skies, with Katalina hoping to rout the enemy and celebrate a victory.

As she prepares to sortie, Kriemhild asks Rapid to bring reinforcements once she's pinpointed the enemy location. Rapid takes a liking to Kriemhild and offers her an invitation on her train, who politely declines as she has a prior appointment.

It is then revealed that Kriemhild's equipment was enhanced with Martian technology just as she spots the enemy, a massive Martian weapon. She quickly realizes that it's on a rampage with no one controlling it. She then begins the operation to destroy the weapon.

Kriemhild manages locate and destroy the weapon at the cost of running out of fuel to patrol the skies. Rapid and her supply unit arrive to wrap up the operation. Kriemhild decides to take Rapid's train back to base, who's more than happy to bring a cute girl aboard her train. Rapid's men plead with her to also board, but she flatly refuses them, much to their disappointment.
