Klaus und die anderen versuchen die Silvana zu erreichen, die sich im Kampf mit Exile befindet. Als sie den Grossen Strom betreten bemerken sie, dass sie von einem fremden Luftschiff verfolgt werden. Anscheinend wird das Schiff von Dio geflogen.
Exile enters Disith territory, followed by the Guild and alliance fleets. The alliance fleet loses one-quarter of its ships after Exile continues its indiscriminate attack, but Sophia orders it to continue at all costs to defeat the Guild. In the Grand Stream, Dio pursues Claus's vanship and relives their race at Horizon Cave. However, when he realizes Lucciola is not with him, Dio falls into despair and is thrown off his vanship by a gust of wind. Just as the alliance fleet falters in its attack, the Urbanus leads the remaining ships in protecting the Silvana as she makes a final attack at Delphine's ship. Alex, still a prisoner of Delphine, catches her off-guard and strangles her before breaking her neck. As the Silvana destroys Delphine's ship, Wina hears Alex's final words at her listening post. Claus and Lavie finally cross the Grand Stream into Disith, completing the feat that their fathers could not achieve. There, they find the remaining alliance fleet and bring Alvis to Exile. Claus recites all four Mysteria, to which Alvis responds, and Exile sheds its defensive cocoon to reveal a starship. Inside it, Claus and Lavie find their fathers' vanship and remains. The world they have been living in is revealed to be in the shape of an hourglass, and Exile takes Claus, Lavie, and many others to a new, conflict-free world. Claus and Lavie are reunited with Dunya and Mullin, the latter of whom has recovered from his injuries. They are joined by Alvis, Tatiana, Alister, Holly Mad-thane, and several children.
Alors que Delphine, le Silverna et l'Urbanus s'affrontent près de l'EXILE, Dio, pas tout à fait sain d'esprit, poursuit Claus et son équipage vers le Grand Courant.
ラウスはアルとともに、グランドストリームで交戦中のシルヴァーナを目指す。
El exilio entra en territorio de Disith, seguido por el gremio y las flotas de la alianza. La flota de la alianza pierde una cuarta parte de sus naves después de que Exile continúe su ataque indiscriminado, pero Sophia le ordena que continúe a toda costa para derrotar al Gremio. En Grand Stream, Dio persigue la furgoneta de Claus y revive su carrera en Horizon Cave. Sin embargo, cuando se da cuenta de que Lucciola no está con él, Dio se desespera y una ráfaga de viento lo saca de su camioneta. Justo cuando la flota de la alianza vacila en su ataque, el Urbanus lidera las naves restantes para proteger a la Silvana mientras realiza un ataque final contra la nave de Delphine. Alex, todavía prisionera de Delphine, la pilla desprevenida y la estrangula antes de romperle el cuello. Mientras Silvana destruye el barco de Delphine, Wina escucha las últimas palabras de Alex en su puesto de escucha.
