In the hot springs, Sala reveals to Ange that she has discovered Aura deep underground the Misurugi Empire, and that they must march with all power to the Misurugi Empire through a singular point to recapture it. Sala tells Ange that she trusts her judgment, and that if she were to go to the war front with Ange, she would be very glad. Afterwards, Tusk suggests that it would not be bad to fight in cooperation with a dragon. In contrast, Ange feels anxious because she has become unable to believe anything as a result of the constant lies. She says that it is strange that a former princess would invade the Misurugi Empire. Tusk encourages Ange that she should do what she wants to do, and then tells Ange he will support her to the best of his abilities. Ange is calmed by Tusk's optimistic words. Tusk sexually harasses Ange and is subsequently thrown into the river by her, suffering serious injuries. As they enjoy eating lunch, Lamia thanks Ange. As a result of Tusk's injuries, he is invited by the Dragon women to have dinner with them. The fact that Tusk seems infatuated with the Dragon woman makes Ange very jealous, and she makes a threatening gesture towards them, and then she makes space only for two and waits on Tusk hand and foot. Tusk comments that the meal that Ange served to him was the best. Ange feels a strong kinship with the people of Arzenal, admiring the fact that they are able to live both happily and peacefully, even without Mana. Ange decides that she will go back to Arzenal because it is a comfortable place to live in and also because Momoka is waiting there for Ange's return. After Ange has made her decision Sala arrives. She tells Ange that, because she respects Ange's decisions, and because she is under Ange's debt, when the time comes that they defeat Embryo she would like to continue the games she had been playing with Ange from where they had left off. Lamia is pleased with the growth of her daughter, Vivien and tells Vivien that she should value the friends she met during her process of growth. Vivian decides to go back to the place where her friends are, and promises Lamia that she will return back to her. Before the war takes place, Dr. Gecko tells Tusk that wants to know more about his body, but Ange intrudes. Omiko decides that it is time to inform Embryo of the threat posed by the Descendants of Aura and then, triggered by her words, they start to attack. Ange, Tusk and Vivian head to the Singularity point and embark for the world where they had formerly lived. Meanwhile, Tusk and Ange discuss their dreams, such as wanting to open a coffee shop together, and then they hope that the world will become peaceful in the future. After the Singularity Point opens, find that they are not in the sky of the Misurugi Empire where they originally planned to emerge, and soon they realize that they have been ambushed. Riza is imprisoned in a torture chamber in the Misurugi Empire, where Embryo forces the secret of the army's strategy out of Riza and thus staves off an attack of Sala's forces. Sala's battlefront is pushed back, and Sala is left unsure of how to proceed. She resolves to withdraw, following the advice of Ange and Tusk. Ange makes up her mind to fight in order to give Sala time to reach the Singularity Point and as a result Sala is able to return to the other earth.In response to being attacked, Ange battles a group of people and, in the end, learns that the people attacking her are her former coworkers from Arzenal: Salia, Ersha and Chris. They, who are under control of Embryo, try capture of Ange, but fail because of interference by Tusk and Vivian. Finally, the Vilkiss allows Ange to teleport to Arzenal to avoid being captured by them. At first Arzenal is devoid of people, but suddenly someone appears. Finally, Ange and Momoka achieve a reunion.
