Deploying all the fighting strength it possibly can, Tekkadan attempts to capture Sandoval Reuters, the leader of the Dawn Horizon Corps. During a hard fight against unequal odds, Gjallarhorn's outer lunar orbit joint fleet Arianrhod also joins the battle.

Tekkadan who is now serving as a military advisor to Arbaru, is consumed with preparing the launch ceremony for the Arbrau Defense Forces. At Makanai's request, Tekkadan takes charge of security for the ceremony event.
