The messenger says how awkward the situation is, while Aries respond how catastrophic can he cause after his resurrection. The messenger mentions how the Arbitrators are also busy, she ignores his comment and stays silent. When asked if there is anyone she cares about, she doesn't give him direct answer, only says "That person and that other". The messenger gets the idea and interests him, he inquires which demon that has the right to enter heaven. But receiving no response.

She later sneaks into Royal Biblia Academy, and finds Lieselotte with her sister Selina. As she hides and watching them, following them secretly. While both sisters are bathing, they sense magic power, and Aries breaks through. Lieselotte clashes with her attack by connecting to the Acedia Archive.

As Lieselotte screams in pain, she falls unconscious, Aries then says that she was disappointed with the attack on the synchronization memories. She tells Selina that her power is necessary, Selina had a feeling that she didn't come here to attack them, as on the contrary she is here for something very important. Just then Arata and Lilith barges in. However an unexpected reaction came from Aries as she starts to shed tears upon seeing Arata, calling him the fiendish Demon Lord Candidate.

Instead she invites them both to a meal solicitation. They shower first, and Faunaria asks if there is anyone who likes her, but she refuses to answer. However Maris notes the reaction she showed is the opposite of her answer. Aries says how good friends are such as Maris and Faunaria, but Maris denies that Faunaria and her are friends.

An Arbitrator Messenger suddenly appears and inform the three Arbitrators there will be an emergency call and convocation meeting among all Arbitrator will be held, mentioning one of the Arbitrators who has been away from heavens for a long time has returned.

Aries chose Selina, and then introduces herself. She then informs Akio of the situation they are working in, which Aries explains using her time orb. Explaining the Goddess of Darkness revival that would annihilate mankind, which all dimensions, space-time will she fuse with. But says her future is not 100% accurate.

However she suddenly notices that the 3rd phase transition of Nornil Giants the revival of three pillars, and a sudden strong shock wave blast came from afar, which knocks all the books away as well as destroying the room they were in. Even though Selina complains that she haven't studied anything, Aries reassures her that the basic idea has been researched, and there is no problem in terms of knowledge as she can master them 100%.

An Arbitrator Messenger appears before Aries informing her there will be a convocation from the Arbitrator leader. The messenger also invites Selina. Multiple Messengers then arrive and clean the area. Aries calls for a shortcut, and suddenly a portal is opened beneath her, as she descends on her Arbitrator Pillar. It is revealed that Harukage opened the portal to summon her there, as it's an emergency. Aetheria says that the Goddess of Darkness is in her Awakening Precursor, and the Giant Nornil Pillars have revived. Aethera orders Maris to explain to the survivors of the last war. As Maris summons a sphere that project images, she start explaining about the Great Magic War and the Giant Nornil Pillars, including the Twilight Library crisis, Aetheria summarizes it's a tradition that makes the creatures of the world of predation into their own army.

In the project sphere, Deus Trinity manages to project himself there as an astral-body speaking through the sphere. promoting to help the Arbitrators, but Aetheria has her doubts if there is a chance he will fall into the goddess side. Stating that it is dangerous when facing the Goddess of Darkness, so Aetheria turns his help offer down. But Aries notes that they have 0% win rate against Nornil Giants without Deus Trinity help, confusing Aetheria to make a decision. In the end she accepts his help. Then all the Arbitrators witness his power by destroying his Giant Nornil Pillar with such ease. Surprising Aetheria. Aries remains silent, then she mentions that the remaining two Pillars of Nornil Giants has weakened due to the disappearance of Versand. Finally Aetheria ordered all the Arbitrators to move to the Twilight Library.

Later in Heavens, Aries who was with Selina were visited by Arata. He brings cake to the both of them which was sold in heavens. Aries requests support from him for Selina's anxiety. Whom she is having a hard time understanding Thema's. Arata wonders if he can give her a hint, encouraging her that she is a strong mage, to which Selina pleads to. Arata tells her to pretend to be like Liese, which Selina becomes flustered to do so. Aries questions Arata if it is important to do so, however Arata responds that Selina looks excited about her sister. She tries imitating her sister by how much she loves Arata. However both Aries and Arata are at a loss for words. Aries points out there is a decisive difference between Liese and Selina. Selina thinks to herself how her sister always kept moving forward without stopping. Selina finally figures out the key is her memories with her sister.

A powerful magical torrent surround Selina's body, and Aries notes that she's connecting to her Thema. Selina then sealed and released a gate of Melancholy, She is transformed with a new Thema and outfit. Aries then announces with this all the Arbitrators are ready. Arata with Aries then watch from a building the heavens place, he tells Aries that he thought that the Heavens were similar to the Sky Library, he says that it's really a big city. Aries tells Arata that the heavenly world is a foundation world. Civilizations of all worlds are selected and developed. Arata finds it a very convenient world, comparing it to a paradise. Aries tells Arata that she has encountered a different dimension isotope devil demon candidates, Chronos Trinity the Demon Lord of laziness, one that is dangerous and evil, and a horrifying demon king. However she finds Arata a natural one, whom fear does not exist, it is doubtful. She asks him that he is now the Demon King, wanting to know his condition, responding that he feels like a fool. Aries gets confused, Arata clarifies that everyone looks great and is drowning in power and grinning, he thinks of it very embarrassing.

Aries asks him that if being one have a devilish attitude, Arata agrees so, remembering his father Deus Trinity calling him how gentle and dignified atmosphere is rather scary yet cool. So he tells her, he decided to do the Great Demon King with the usual laughing appearance as much as possible. Aries changes the subject and thanks him for Selina's awakening. Though Arata says he needed her for what he is going to do, since her new Thema and magical power are absolutely necessary. He tells Aries him, everyone, and the Arbitrators want to have such a rule that even the goddess laughs and has a good time. She asks him if he wants complete control. Aries extends her hand, mentions to him that she will fully cooperate with him. She then becomes flustered, denying naughty things. She then shakes hand with him, informing him that the cooperation of the Arbitrators will be essential in the future. However this hand shake triggers a memory in Arata's mind, in which Aries is eating crepes, asking her if she likes them, which shocks her. Aries figures out it's from other timeline, which they both had mixed consciousness of the hand shake. Aries then teleports away from him, and with a serious look, she tells him that this time he will definitely protect thinking to herself that even if he is the Great Demon King who controls all the even the probability world. Arata smiles and tells her that he is relying on her.

She is later seen wielding Dáinsleif at an heaven building with Maris and Faunaria. As Faunaria is fired up that they are all in the field as well, Maris jesting by saying Faunaria is staying, which annoys her, and Maris says that of course not since they are on the front line. Shouting, Faunaria seems to hate this lie. Aries interrupts them and says them that it's time to depart. As the trio descend the to the earthly world.

When the Heavenly troops are brainwashed by Skald ability, and started attacking Faunaria, Aries teleports next to her, which Faunaria confused at the situation she questions Aries about the details. Aries informs her that the three goddess remaining Pillar, Skald, has began his process of meddling with space-time. Which are the Heavenly army memories have been meddled with so they are not protected against brainwashing attacks. Faunaria understands the situation, that weaker Maguses and the Heavenly people are getting brainwashed. She asks Aries how should they proceed now that the enemy numbers are going. Aries tells Faunaria that the Arbitrator head, the allies, and the consultants of Heavenly army are biding time for them to regroup. Faunaria questions Aries about the allies, to which Aries points her finger at Arata and Deus Trinity as they destroy the enemy. After that Arata winks at both Faunaria and Aries, which Faunaria finds it annoying and Aries simply finds Faunaria reaction unreasonable.
