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 the Arzenal arming up their defenses, hence Julio commands to attack and make assault on Arzenal. Jill also orders Salia to guard Ange and Mei to bring Villkiss underground where she and her crew descends to a submarine built underneath Arzenal. Julio's troops make way to Arzenal and start killing people. Meanwhile, Ange becomes stubborn and defiant to Salia as she and Momoka manage to escape then head to the cafeteria. However, Julio's troops apparently attack Momoka but Ange draws fire to save Momoka and interrogates one of the soldiers. Ange decides to head out and confront Julio using Villkiss. Ange heads to the hangar and leaves Arzenal using Villkiss, attacking 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. Using the power of her ring, Villkiss turns red and destroys Julio's ships. Ange notices also a light barrier protecting her 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, annihilating Julio's naval fleet in 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, turning Villkiss into blue. Black Angel shoots but Villkiss suddenly disappears along with Tusk and Vivian. Back at Arzenal, the submarine commanded by Jill finally becomes operational.
