On the Aurora, Salia brings Jill back to the hangar bay and asks for a stretcher, but Jill refuses and reconciles with Salia with her dying breaths. The convergence starts up again, but Aura shields them and tells them that the Villkiss can take them to the place Embryo is hiding out as it will answer the desires of it user. Meanwhile, Ange wakes up in a bed in a familiar place, afterwards, Embryo plans to start a race with Ange due to her strong will, but she refuses. As she tries to attack Embryo, he backhands her. Back on the Aurora, Hilda reluctantly asks Tusk to use the ring to wake up Villkiss as he had a stronger bond with Ange, but nothing seems to work. On Arzenal, Embryo corners Ange who is calling for Villkiss, but without the ring it does not answer. He prepares to violate her when she starts singing the Endless Song, which Tusk hears and pleads with Villkiss to help protect Ange. It wakes up and links with the other two Ragna-Mails and Sala's machine. Tusk, Hilda, Salia, and Sala warp to the space between space, and Sala then starts to sing her portion of the song. After that, Tusk frees Ange and picks her up, they reunite. He gets off and prepares to duel Embryo with Sala's sword. Ange prepares to battle when the Villkiss transforms once more into Knight Villkiss and she and the others face off against Embryo's machine and summoned copies. On the ground Tusk injures Embryo, realizing that it is the original he presses on, despite getting injured. In the sky Hilda and Salia both realize that their machines are the same and they both gain control of them and they destroy the copies. Hilda, Salia and Sala criticize Embryo for treating women with violence and sexism. Ange fires hers and damages the machine, destroying it altogether, while at the same time Tusk kills Embryo. Arzenal returns to the real world and Aura thanks them for their help. The entire group returns to the island where Ange voices her intent to work peacefully with the DRAGONs, while the other world's citizens decide to live by themselves.
Act OneJill and Salia arrives back to Aurora, while Salia was pleaded for a stretcher where Jill said it's too late and asks for a cigarette. Jill talked about how Salia was like her sister and talking about her past actions to Salia, without finishing her sentence, Jill passed away. Aura then communicated with the group, telling them where Embryo is, also informing them that Villkiss is the only way to reach to him. Meanwhile, Ange woke up in the unparalleled universe where she tried to find the exit, and only to discover the original Arzenal when Embryo greeted her. Ange tried running away however Embryo can still find her because it is not the Arzenal Ange knows. Embryo told Ange his past and why Arzenal is teleported here, where everything began. Ange tried summoning the Villkiss to run but failed since she doesn't have her ring, leading to Embryo stripping her clothes off to "purify" Ange since she was sullied. Hilda suggested Tusk to go on the Villkiss since he is the one who is most connected to Ange, with lots of begs for Villkiss to work. All of a sudden, Villkiss responded to Tusk and started functioning. After everyone giving their final words before Salamandinay, Tusk, Salia and Hilda go and find Ange, they disappeared.
