The story begins with Arata, Lilith, Lugh and Akio went on an investigative mission to a certain ruin site. Akio revealed that it is the hometown of Akio where the Sky Library is at. Suddenly, a flash of light appeared from the sky. It is a beam that is shooting downwards towards them from the sky. Arata tries to counter it by using his powers but fails. The group braces for impact. They suddenly reappeared in the Sky Library after the impact.
Lugh decided to betray by attacking the team as she declared that she is only there to lead them the ruin site and have no intention to join their exhibition. She was then bound by Liese's magic as Akio reveals Selina's camera that she brought with her. Arata decides to release Lugh after she agrees to join them but immediately attacks them and to find herself getting her bind again. This cycle repeats itself multiple times.
After a moment of time and successfully binding Lugh multiple times, a certain figure appears who later reveals that he is a Demon Lord, Abyss Trinity.
