Étude Lavie.Lavie, who is recovering from her injuries on the shipwrecked Silvana, dreams of her childhood with Claus, who moved to Norkia and became neighbors with her. Their fathers, Hamilcar Valca and Georges Head, immediately became best friends and teamed up as vanship pilot and navigator, while Claus's mother Justina Valca treated Lavie like a daughter. Hamilcar and Georges taught Claus and Lavie the basics of a vanship. Lavie recalled a male pilot and a female navigator who were friends with Hamilcar and Georges. One day, Hamilcar and Georges received an assignment with their friends to cross the Grand Stream to deliver a peace proposal to Disith. However, Claus and Lavie soon heard the news that Hamilcar and Georges lost their lives along with the female navigator in their attempt, and Justina died six months later. After being orphaned, Claus and Lavie trained to fly a vanship, eventually selling their house to keep the vanship and training for courier missions. When Lavie finally awakens, she cries from the memories. Dio and Alister locate Claus and Tatiana near the landing field of Disith migration capsules. After reuniting with Lavie, Claus informs her that their hometown of Norkia has fallen to Disith.
