Chronology
At Arbitrator Headquarters she held a meeting at Master Biblia welcoming to heaven, and speaks with Master Biblia when he asked about the missing Heavenly Arbitrator, she informs him, she hasn't seen her for years, and she is probably playing in the outside world. He later mentions that he only came to introduce new candidates for all the Arbitrators, as Mira, Akio and Selina show up. Aetheria then comments that since they are missing everything, she is glad that Master Biblia and Master Liber are back. She also welcomes the other three and thanks them for their entry. She then tells Mira to follow her and that her daughter told her to improve. Mira at first is confused when Aetheria mentions her daughter, informing Mira that Master Akasha is her daughter as in their world. Later in Yui's dream it is shown that Aetheria has been training Mira to improve her as a Hero candidate. Mira is later seen concentrating into her grimoire while Aetheria is reading a book. Aetheria then summons all the Arbitrators for an emergency meeting, by sending the Arbitrator messenger conveying a message. In the Arbitrator headquarters, it is revealed that the Goddess of Darkness and the Nornil Giant pillars are reviving. Instead of her explaining the situation, she orders Maris to explain to the survivors of the last war. Aetheria at first displeased when Master Liber yawns, then Maris obeys her. Maris uses her ability to summon a sphere that show images, explaining the details that one of the pillars of the Giant Nornil pillar has reaffirmed in their dimension. As well as they completed guidance to the Twilight Library against God by the world tree. At the same time as recognition more than 90% in the Twilight Library became a genus of Verzand. Aetheria explains that it's a tradition that makes the creatures of the predatory world into their own army. When Faunaria and Maris were arguing, that Faunaria can't win against them alone, Harukage mentions at the time, there was no strong human resources during the Great Magic War. As she glances towards Aetheria they both seem to agree. As Harukage seems to know more about it, she says that there was a consultation for cooperation regarding the shortage of human resources in heaven, asking Aetheria to connect to it. Aetheria doesn't seem to like the idea as she have a bad feeling but she will listen anyway. As Maris was about to project it, instead Deus Trinity shows in the projection sphere, introducing himself to all the Arbitrators. Telling to all the Arbitrators that he will help them, however Aetheria inquires the kind of soul is his senior. Deus is at mystery by her question but is told by Radix that he once used to be the "Pride" Arbitrator. He tells Aetheria that him as a former Great Demon King, he'd help Arata who is now the Great Demon King, which shocks Aetheria. However she inquires him if there is any guarantee that he will fall into the evil goddess side. Smiling as he says that it's dangerous when facing the Goddess of Darkness, Aetheria simply then denies his so called help. However Aries mentions that they have 0% survival rate for the Nornil Giants without Deus Trinity help. Confusing Aetheria to make a decision for help or not. When she glances over to Harukage she simply smiles. Though not entirely satisfied, as per her request the least he can do is to help the newcomers which he agrees. She then tells him to get rid of one of the Giant Nornil pillars, as he understands so. All of the Arbitrator witness his power via Maris projection sphere. As he easily destroys the advent of Versand waves, using Dante Cross to destroy one of Nornil Giant pillars and Nozomi-Versand. Aetheria is surprised that he was able to defeat such a pillar of god with such ease. Harukage comments that the research reports say it is possible to subdue one of the three pillars of Nornil Giants. Murakumo tells Aetheria that with only two pillars left, they can win, and beat the goddesses at once. Aetheria says though that everything is like a speculation of Master Biblia and Deus Trinity, besides she doesn't like it very much. Aetheria then finally orders all the Arbitrators to start moving to the Twilight Library, as well that the heavens will also do their best subdue the remaining two pillars of the Nornil Giants to the front.

She is later seen in the outside world with her fellow Arbitrators divided into two groups, she along with Maris and Faunaria ready to fight the gods. Before the battle starts against Nornil Giant Pillar, Aetheria contacts Arata via a communication screen. She greets Arata, and introducing her identity as the leader of the Arbitrators, likewise he greets her, telling her that she looks very similar to Arsha. Aetheria thanks him but tells him that he has no modesty, as well as to leave those topics to her daughter, Arata is shocked that she is the mother of Arsha and that he is independent to her. Aetheria asks him if he knows the purpose of this battle, Arata answers after defeating the three pillars, the goddess Aryan will appear which they will fight her. She tells it's true however she doesn't know what Harukage has told him. Arata inquires that after the Arbitrators defeat the goddess a crisis will occur, upon hearing what Harukage has informed him Aetheria is not pleased, finding it as an insult to them Arbitrators and nothing more than nonsense. Arata says that he was surprised as well, Aetheria changes the topic back, informing her as for this battle only the Heavenly troops will fight, and Demon Lords don't need to interfere, he agrees so but says he will help if they get into any trouble. Aetheria tells him that she really hates that insolence of him and closes the communication screen. Aetheria later is seen ordering the Heavenly troops to attack the Nornil Giant Pillars unknown monsters, defeating them quickly. Aetheria watches from a communication monitor, Faunaria defeating them in quick succession because she can fly, however the problem lies within the kin who've fallen under water. She then requests Maris to increase the radius to 30 kilometers which Maris says that she treats them magicians very roughly. Maris then changes the ocean surface to ice by activating an ice barrier skill, making fighting on the surface should pose no problem. After the kin who have fallen under water is weakening due to the ice barrier, Aetheria orders her Heavenly troops to wipe out the rest. Then Faunaria mentions that they somehow can managed the first wave of Ulzwiad. Maris and Aetheria look up in the sky and Maris says that she's getting closer, Aetheria then is hit by a strange light along with all her Heavenly troops, Aetheria mentions that the defense mechanisms against brainwashing have been destroyed. Both Aetheria and Maris are surrounded by the brainwashed Heavenly troops, however Aetheria mentions this all falls within her expectations, she kills all of them with ease mentioning that harming her, a wielder of the Arms Mastery, even if they are being manipulated a childish prank has gone too far. Maris assumes that as long as they are a 'thought' of weapons anyone can be freely manipulated, as she hasn't this magic in a while but rather finds it nasty. Aetheria agrees as she doesn't find it to be elegant.

Aetheria then contacts Faunaria and all the Arbitrators including their allies to tell them that one who takes absolute nothingness, the desire of despair "Skald" has begun to meddle with space-time.

Along with Harukage, she is seen fighting off the last Nornil Giant Pillar. After Arata and Deus Trinity destroy it, she along with the rest of the Arbitrators, Arin, Arata and Deus Trinity observe as it evaporates in the air. The Arbitrators troops celebrate their victory. Aetheria comments that's it's thanks to the Great Demon King Army and the Trinity Seven were a success. Harukage converse with her, saying that without them, this victory wouldn't have been possible. However Aetheria does admit that the heavenly army alone couldn't subdue the three pillars of the goddess's, and that she hates it, but she is grateful to them. Harukage teases her by calling her this is her so called tsundere attitude, Aetheria responds by glaring at her with annoyance. When Master Liber says to Murakumo that the reason why the goddess of darkness hasn't arrived yet, is that according to the concubine prophecy, there seems to be some time now. Aetheria hears this and tells the Arbitrator to take a rest, and she will contact Faunaria.

Aetheria along the other Arbitrators announces that the Goddess of Darkness has finally appeared. A sudden surge of magical power circle around them, and attacks them, injuring Aetheria. As well as the rest of the Arbitrator who managed to protect themselves, except Maris and Aries who were badly wounded. Master Liber transforms into her adult form, and protects herself. Aetheria decides to get serious, seeing the situation isn't like Nornil Giants. Harukage jokes around her, when they will be captured, which simply sighs at her. Aetheria decides to overturn the prophecy of the Great Demon King, and removes her glasses, she then connects to the Superbia Cloud Archive, using her most powerful move, to summon machines, vehicles, and airplanes. Ordering them to defeat the Goddess. Along with Harukage ultimate move. Faunaria is stunned at their moves. Suddenly the Goddess's arrive at their location, and both Aetheria and Harukage are being confined in black crystal.
