Claus and Lavi are back at their home, with Alvis sleeping on their bed. Claus has decided to take the mission, much to Lavi's annoyance. Alvis awakes and asks for her nanny, Gita but the woman died during their escape. Claus isn't sure how to handle it, but Lavi tells Al that Gita had to go away for a while. After eating, they settle in for the night, but the star-shaped ship finds Al in the house. Claus and Lavi have to escape, and their house is destroyed in the process. Although they don't use their engines in the waterway, the star-shaped ship still finds them. They narrowly escape, appearing to damage the star-shaped ship enough to do so. At the temple ruins, where they were to bring Al, they are attacked again and the star-shaped ship snatches Al. Claus tries to fight it with a rock and is knocked out. Just as he is about to be killed, a shot rings out. Alex has shot the pilot of the machine and saved all the children.

The Sylvana lands for refueling and supplies, when they are faced with potential brawl with the crew of the Goliath!

While Lavie recovers from her injuries on the crashed Silvana, she dreams of her childhood with Claus, whose family moved to Norkia and became neighbors with Lavie's. Their fathers, Hamilcar Valca and Georges Head, immediately became best friends and teamed up as a vanship pilot and navigator. Claus's mother, Justina, took care of Lavie as if she was her own daughter. Valca and Head taught their children to fly a vanship and assigned them mock courier missions. Lavie recalls her father's two friends, a male vanship pilot and a female navigator, but cannot remember their names. One day, Valca and Head received an assignment to cross the Grand Stream to deliver a peace proposal to Disith and left with their two friends. However, Valca and Head lost their lives in the attempt, and Justina died not long after. In a separate dream, Alex Row sees the two vanships in the Grand Stream. After they were orphaned, Claus and Lavie began training to fly a vanship. They were eventually forced to sell their house to save the vanship and began training for courier missions. When Lavie finally awakens, she finds herself crying from the memories. Dio and Alister finally locate Claus and Tatiana near the field of Disith migration capsules. Claus is reunited with Lavie and informs her that their hometown of Norkia has fallen to Disith.

A portion of the Guild fortress breaks apart and falls away from the Grand Stream into Anatoray.

Dio is then left in the care of the Mad-thane residence, which has been converted into a makeshift hospital. Claus takes Alvis back to his wrecked house, where they stay overnight. The combined Anatoray and Disith alliance fleet launches a surprise attack on the Guild fleet and, helped by the vanship squadrons, emerges victorious. It continues to pursue the withdrawing Guild ships into the Grand Stream. When Claus and Alvis are finally able to contact Lavie and the Silvana with Lucciola's communicator, they are told to make a rendezvous at the Dragon's Fangs.
