The story revolves around the Amakusa-Style Remix of Church being tested by the Church of England to become part of it.

Chapter 1
After the events of the Orsola Aquinas Rescue Arc, the Amakusa Christians are eager to join the Anglican Church, and be under their protection from the Roman Catholic Church.

After being briefed of the rules and goals of the Necessarius Special Admission Test by Freadia Strikers, they begin their test in Necessarius' Underground Labyrinth, the prize for their passing of the test would not only be their inclusion into the Church's ranks but as well having the privilege of a free pass that allows them to access Necessarius facilities that are otherwise are locked by magic barriers.

However, after Itsuwa and Tsushima came upon a Cursed Corpse Wax trap in the underground labyrinth, Tatemiya Saiji informs them that their communication with Freadia has been intercepted by a fake, while the real Freadia's communication has been intercepted by fake Amakusa Christians. Immediately, they become aware of the fake Freadia and the fake Amakusa Christians, to obtain the free passes to Necessarius' facilties, which hold powerful spritual items and grimoires.

They get out of the labyrinth but know that their troubles have just begun as now the Church will suspect and target them, knowing that only they can hunt down the fakes and clear their names. Meanwhile, Freadia discovers the communication spiritual item has been tampered with remotely, and believing that the Amakusa are the cause, reports to her higher-ups that they are her suspects. She is then ordered to take them down.

Chapter 2
And thus the Freadia gathers his ilk to hunt down the betrayers, the Amakusa. She meets up with Flack Anchors and his subordinates, and makes no attempt to research him. However, she does question their objectives as a tests, and though he shows that he believes that the "Amakusa's" target is the city library where grimoires are hidden, Freadia notices that he has a reply that is unbecoming of a specialist.

Meanwhile, the Amakusa themselves are on the move, hiding from the Anglican Church, they concluded to clear their name as fast as they can as Church and their enemies will not. And so, they go towards the library, which they believe is the likeliest target by the pretenders with their free passes to infiltrate. They steal a truck and rush towards there, foiling Torquay Shadowmint's, of Necessarius, attempts to destroy as they drive pass a hospital.

Back with Freadia, she and Flack, believing that the fakes are there arrive at the library, but already she notices that the traps have not been disturbed. She takes a look at the repair and finds no one there, but then she is struck down by Flack. There, the betrayal is shown, and that Flack and his subordinates were the pretenders and the person Freadia spoke to in her cursed crystal radio was pretender as well. She is felled by them with their magic rifles.

The Amakusa arrive and see Freadia bloody but alive on the floor, and they are then engaged in combat, injuring several of them with Flack's rifles. They are forced to retreat to contemplate and mull over their tactics. But when their time was almost up, Itsuwa charges towards. Seemingly outnumbered and overpowered by Flack's group they use their rifles to attack, but Itsuwa uninjured, for she struck her spear on to the floor to make a sound. There, it is revealed that their weapons use the sound the target hears to injure them, and quickly Itsuwa charges. The subordinates try to defend Flack, but it is too late, for Saiji and the others have sneaked away and crashed a book case on their heads.

Now then, they discover that the grimoire the group was after was the Necronomicon, a fictional one, but then defictionalized by a magician. There, they also discover that Flack was bleeding, and now they see that he had read the book and that it was a true grimoire, and that he has sent forth it to parts unknown using the sound of his magic rifle. Meanwhile, near Westminster Abbey a trucked is parked. Inside, several people fall down after hearing of the contents of the Necronomicon, and there efforts were not vain, for it was then collected and made a whole again into grimoire, and now a mysterious person now holds in his hands.
