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.

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.

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 an answering machine.
