As Julio's fleet advances to Arzenal, Jill orders the entire staff to ignore the message and prepare to defend themselves as she initiates Operation Libertus. The naval fleet sees Arzenal arming up their defenses causing Julio to command an attack on Arzenal. Jill also orders Salia to guard Ange and Mei to bring the Villkiss underground where she and her crew descends to a submarine built underneath Arzenal. Julio's troops make their way inside Arzenal and starts killing people. Meanwhile, Ange becomes stubborn and defiant to Salia as she and Momoka manage to escape and head to the cafeteria. However, Julio's troops apparently attack Momoka but Ange draws fire to save her and interrogates one of the soldiers. Ange decides to head out and confront Julio using the Villkiss. Ange then activates the Villkiss' powers giving it a new red color and attacks the soldiers and their mana-powered weapons as she heads to Julio. Salia tries to stop Ange but Ange tells Salia that she started to like Arzenal so she will protect it and slashes Salia's Para-Mail arms to subdue her. As she is attacked by enemy units, Ange notices a light barrier protecting the Villkiss. She finally confronts Julio and as she is about to deliver the killing blow, Embryo interferes using his Black Angel Ragna-Mail to stop Ange. Embryo taunts Ange and suddenly sings to activate its powerful attack, killing Julio and annihilating his naval fleet in the process. Ange seemingly survives Embryo's attack and Embryo set his sights on Tusk and Vivian. Embryo sings again and Ange tries to save Tusk, transforming the Villkiss again this time giving it a bluish appearance. The Black Angel shoots but Villkiss suddenly disappears along with Tusk and Vivian. Back at Arzenal, the submarine commanded by Jill finally becomes operational and they leave the base.
