Army of brainwashed soldiers comes crashing on close to them, Faunaria and Aries who are above them feel an impact caused by Arata destroying the brainwashed soldiers. Murakumo suddenly flies above them using a pair of wings, and hums that she will be going first, Faunaria shouts at her that she wants to go as well.

Murakumo walks around and is disappointed that it's over already, and the goddess of darkness isn't yet shown herself. She notices Master Liber who mentioning according to the concubine's prophecy, there seems to be some time now. Seeing if that's the case, Aetheria tells the Arbitrators it's for them to take a break then.

Murakumo along with the rest of the Arbitrators, as well as Master Liber transforms into her adult form. Faunaria shields both Maris and Aries. The goddess then suddenly appears in their location and confines both Aetheria and Harukage in a black crystal. Murakumo attacks her, using one of her swords. However she notices her sword was eroded, and figures out it was due she was connected to the Sacred Chest. Liber informs her, the higher the connection to an Archive, the stronger the erosion becomes, such as the case with Aetheria and Harukage. Liber says to Faunaria to run away to the Great Demon King. Murakumo says as well as it is a line she wanted to say once, to leave it to her and run away. Though Faunaria refuses to let her fellow Arbitrators fight the goddess alone, they leave it to Aries to run away. As they take flight, Faunaria cries for them. Murakumo uses another way to fight the goddess, by utilizing a two sword-style, which manage to injure the goddess, whom is interested in her techniques, which according to the goddess it's a conceptual martial art to cut and kill.
