Dio and Alvis reminisce about their home world Prester, divided into two nations called Anatoray and Disith. They think back to when they each met vanship pilots Claus Valca and Lavie Head, who joined Alexander Row, captain of the Silvana. Dio recalls Maestro Delphine Eraclea, his older sister and leader of the Guild, who sought Alvis as the Key to the Anatoray-Disith Exile. Dio's best friend Lucciola was also reintroduced, and he later sacrificed himself to save Claus, Alvis and Dio, shortly after Dio was driven insane by Delphine. Anatoray and Disith united against the Guild and defeated Delphine. Alvis activated the Anatoray-Disith Exile, using it to transport some of the people of Prester to Earth to start a new world with peace. In the present, Alvis laments that there is still world conflict, but Dio encourages Alvis to live on. Dio and Alvis are later chased by Guild Starfish, which Dio declares that he will protect Alvis as he had promised Claus. Meanwhile, on a mountainside, Lavie heads to her vanship to cheerfully collect a sleeping Claus from the cockpit with a wheelchair.
