As the Silvana and the Urbanus continue their search for Exile, Sophia briefs the vanship pilots on their strategy to capture it. Sophia asks Dio to fly as Claus's navigator, but he refuses from fear of being found again by Delphine. At Horizon Cave, Nestor proposes that the Claudia unit capture plan be accelerated after the Guild recalls several units, but Duke Mad-thane appeases him to wait for the scheduled operation on Covenant Day. On the final day of the Guild's Birth Week, Alvis surprises Dio with a birthday party, much to his delight. After days of searching, the Silvana and the Urbanus locate Exile, and Dio agrees to fly as Claus's navigator to assist in its capture. The Guild locates Dio on board the Silvana, and Delphine orders Lucciola's brother Cicada to retrieve him at all costs. As the vanship squadron attempts to anchor cables onto Exile, the ship's defense system activates, but it is able to complete their objective after identifying an unprotected section of the hull, with Dio's help. Alex hands Marius's Mysterion to Sophia and tells her to return to the Urbanus. Just before Claus and Dio return to the Silvana, Guild fighters land on the flight deck.

Le Silverna et l'Urbanus entre dans le Grand Courant à la recherche de l'Exile. Maestro Delphine décide qu'il est grand temps de récupérer Dio et Lucciola, toujours à bord du Silverna.

Die Sylvana hat das Exile bei ihrer Suche im Großen Strom gefunden, aber können sie es auch einfangen?

La Silvana e l'Urbanus proseguono la loro ricerca dell'Exile utilizzando i torpedini acustici, ma per giorni non captano nulla se non dei relitti di navi abbattute e restano con soli tre siluri e ancora cinque settori del Grand Stream da analizzare.

作戦決行は、山羊月13日の 04:00。それに向けてグランドストリームでの、シルヴァーナとウルバヌスの隠密作戦は続く。
