Aries is later seen observing from afar in one of the Arbitrator floating buildings, as the Trinity Seven fight Deus Trinity. Accompanied by an Arbitrator messenger, whom they chat. 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.

Lieselotte mentions her knowledge of Arbitrator duties. Aries then hugs Lieselotte stating that she misses her and wanted to see her. Naming her the mage of another dimension thus acknowledge her now. Just then past memories flashback through Lieselotte when she was with Aries, remembering her past. As Lieselotte screams in pain, she falls unconscious, Aries then says that she was disappointed with the attack on the synchronization memories. As this is the destination of those Infinite God, and since Lieselotte Sherlock regained her past memories, the stability of space-time is inviable thus if worst comes to worst she will be forced to exterminate Lieselotte, which horrifies Selina. She then requires Selina's help, 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, she then teleports away. Arata rescues the unconscious Lieselotte and wonders why Aries was crying.

Aries later seen in one of the Arbitrator buildings, as she is approached by Maris and Faunaria, Maris then inquires if she came to pick her up and Faunaria (after their battle with Master Liber and Lugh).

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.

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.
