Private Namie Portman arrives as a transfer member to the 8th Autonomous Unit. The unit receives three new ZTK5 SEIRAN Trail Kriegers, to which Namie was the test pilot for. Namie joins Silfy Appleton, Lorenz Giuliano, and Tokimune Susumu in a mock battle that reveals Namie's inexperience in real combat. Ingelmia sets up base not too far from their position. They head out to attack it, during the fight the units four Trail Krieger pilots blitz the enemy and swiftly destroy several enemy Trail Kriegers before they can mobilize, but after saving Tokimune, Namie is blindsided by an enemy Trail Krieger. Tokimune rushes in to save her, by plowing through the enemy with gunfire then on to stab the offending GUNBASS. After the battle, Jamie Hazaford notices that Tokimune's linkage rate with ARGEVOLLEN spiked to 76%.
