Summary
Upon witnessing the Arata's transformation after rescuing Lilith, Mira and Arin are surprised by his attire, the Demon Lord Trinity Form. Master Biblia also remarks that Arata has finally reached that level.

Elsewhere, Master Liber, sensing Arata's growth as well, comments that her research is yielding while Hijiri, inside a crystal, cries tears of happiness.

In Sky Library, Abyss is shocked that Arata has surpassed the Trinity, possessing access to four Themas and Archives: When Abyss demands an explanation of how Lilith was liberated, Arata explains that he gathered all of the magic from the Luxuria Archive within him into Lilith in order to gain control of the key. Additonally, Akio had strengthened him with Mantra Enchant while Lieselotte analyzed the magic, along with Sora and Ilia supporting their bodies. Arata then declares to Abyss that through the strength of his friends, he will use his magic to overcome his destiny. Abyss attempts to retaliate, however, Lugh disarms the Crimson Demon Lord in favor of her future husband. As Arata prepares to strike Abyss, he explains that the reason the Demon Lord was defeated is because he never made friends before slashing him. As he disintegrates, Abyss smiles while the Sky Library crumbles and falls apart.

After awakening, Arata finds himself one more in the ruins of Akio's hometown, wondering if he is within her dream again. However, the former Spriggan reveals that they are in the real world while commenting that her homeland is as barren as ever. Relaxing, Arata then discovers himself touching Lilith's breast, although she remains asleep along with the rest of the girls. Akio explains that she had forced herself to awake first in order to embrace Arata, expressing her gratitude. Nevertheless, Arata insists that he should be grateful since he can bring her home to satisfy Mira and her mother. Suddenly, the Manta Enchant symbol within Arata activates, unveiling the spirit of Akio's mother.

Akio begins to cry while Arata understands that her mother and the people from her hometown had lended Akio their strength. As Arata witnesses Akio's childhood, Akio reunites with her mother for the last time, before the two bid farewell to each other. Afterwards, Akio, in her normal appearance, expresses her appreciation to Arata once more. Arata then wonders about the Sky Library, which Judecca, as a pendant, appears and reveals that the Library completely annihalated. Judecca reveals that she can change into any form of his desire, even as a "bouncy" female much to Arata's happiness. However, a displeased Lilith overhears their conversation and despite Arata's efforts to appease her, results in the teacher chasing after him. Lieselotte remarks that she is jealous that the two suit one one another, to Akio's surprise and embarrassment after learning she was awake the entire time. Regardless, the two agree that they enjoy being with Arata. While Lilith continues to pursue Arata, he delightedly notices a plant beginning to sprout, although an unknown mark has appeared on his hand.

Within a crowd at an undisclosed location, a hooded female figure suddenly senses something in the atmosphere within.
