Following Claus and Lavie aboard the Silvana, Dio and Lucciola allow themselves to be captured. At the Anatoray capital, the Emperor begins to distrust Alex's actions and sends the Urbanus to retrieve Alvis. Alex interrogates Dio, who tries to gain his trust by telling him that the Mysterion passed by House Eraclea. He also reveals that the three Guild houses holding the remaining Mysteria have been purged by Delphine. Vincent Alzey, captain of the Urbanus, requests to meet with Alex. Alex asks Claus to fly escort for his flight to the meeting, to which Tatiana objects. Alister defies Tatiana and offers to be Claus's navigator. Alex informs Vincent that he will not hand over Alvis and will fight to keep her aboard. Dio and Lucciola meet Lescius, the Silvana's chief engineer and a former member of the Guild. Dio then finds Alvis by herself elsewhere and reads her one of the Mysteria, after which she falls into a trance and wreaks havoc on the ship's systems.
