Arata and the others appear in a world floating in a rift in the sea of parallel dimensions. Monsters attack. The legendary grimoire, "Fragments of the Iliad" challenges them to a fight. An evil power awakes in Arata due to his anger when the Astil Codex are sealed...

Summary
After "Hijiri" disappears, Sora explains to Arata that the imposter was the Ilias Fragment, a grimoire who replicated his actual cousin's memories and appearance in order to care for Arata while the original was away. After learning of the revelation, Mira insists on investigating alone so that Arata can search for "Hijiri", however Sora interprets her response as jealousy much to the Trinity Seven's denial.

As the trio wanders through the academy, Arata questions if the world is a reconstrution however Sora reveals that the area has simply been sealed within a barrier and isolated in a alternate dimension.

Later the party is approached by a group of demons which Mira attempts to dispatch them with her magic, but her clothes is unexpectedly torn aparat instead to her embarrassment. After Arata provides Mira his jacket, Sora deduces that Magus Mode has been prohibited within the barrier. As a being of magic, Sora is unaffected so Arata and Mira escape while Sora easily defeats the demons. However, the Hijiri imposter next appears where the two grimoires greet one another before preparing to battle.

Unable to depart the building, Arata and Mira find temporary shelter inside an empty classroom where the Trinity Seven borrows the Demon Lord Candidate's shirt. Afterwards, the two discuss an alternative to escaping without defeating the culprit is destroying the core of the barrier. Upon determining that the core can either be in the center or border of the academy, Arata decides to investigate the former while Mira safely recovers in the room. However, Mira insists that she join him as he is unfamiliar with the school's layout which he accepts.

Meanwhile, Sora continues to easily dispatch shadows, determining their identities as the former students of the academy. However, "Hijiri" notes that they are simply puppets which leads Sora to unleash a powerful spell, only to find herself ensnared within a trap set by her adversary. Concluding the battle, the grimoire then decides to meet with Arata, declaring that there was no escape for him.

Arriving at a clock tower in the center of the academy, Arata and Mira suspect the building as the best possible location for placing the barrier's core. But due to Mira's revealing outfit and consciousness of him, Arata decides to climb the tower while carrying her so that she can scout for traps.

While ascending the building, Arata inquiries Mira's circumstances for joining Grimoire Security which she explains that her high magical abilities, as well as her Thema Justicia as her reasons for enlisting. This leads Arata to beieve that she was once a delinquent since a Thema represents the opposite of a mage's personality, prompting Mira to recall her past...

''Inside a classroom, a group of friendly girls attempt to discuss with a nervous Mira about her powerful magic and history. However, due to her fear of losing control over her magic, she quickly excuses herself to avoid being close to anyone.''

Because of her personality, Mira did not have any close friends until Akio, a member of the Trinity Seven, approached the timid girl outside for support on her research, unafraid of her strong magic.

Afterwards, Akio would have Mira join her on several activities and two would soon become close friends.

One morning, Mira attempted to perform a magical experiment alone in a classroom but the process failed which caused a backlash that rendered her unconscious before Akio found her soon after.

''Upon regaining conscience, Mira discovers herself being carried by the Trinity Seven who encourages her to become more prideful of her magic. Akio's encouragement would strongly influence Mira who admired the upperclassmen for her strength.''

After recalling Akio's guidance, Mira becomes embarrassed after realizing she revealed her history to Arata, but the Demon Lord Candidate is nontheless satisfied to learn more about her, as well as assisting in relieving her stress before climbing to the top.

Arriving at the roof of the tower, Arata and Mira discover a confined Sora before "Hijiri" reveals herself to them. With Sora sealed, the Ilias Fragment announces her attention to dispose of Mira and living with Arata together inside the barrier until Hijiri completes destroying the world. After shadows appear to surround the two, Sora privately communicates with her master to stall for time while she determines a method to destroy the barrier's core. As such, Arata negotiates with "Hijiri" to allow Mira to depart while he willingly agrees to stay together with her which the Ilias Fragment accepts his conditions despite the Trinity Seven's protests. Subsequently, Arata questions the grimoire of Hijiri's intentions, but the imposter suggests that he discuss with Hijri after she has completed her goal. Afterwards, the Ilias Fragment sets the shadows on Mira, revealing that she still intends to eliminate the leader of Grimoire Security as no method to passing the barrier existed. Although Arata attempts to intervene, he finds himself bound by "Hijiri" who even deduced that Sora was communicating with him before beginning the process to drain her former associate's magic as a storage. As Mira and Sora begin to suffer, a furious Arata reproaches Ilia as he is content with being cheerful with his friends. Dissatisfied with his powerlessness, a dark aura begins to form around Arata as Sora attempts to warn Ilia but eventually the Demon Lord within Arata manifests before the frightened "Hijiri", Astral Trinity.
