Toaru Majutsu no Index SS: Necessarius Special Admission Test (とある魔術の禁書目録SS -『必要悪の教会』特別編入試験編) or Toaru Majutsu no Index: Necessarius SS, previously known as Toaru Majutsu no Index SSS is an upcoming light novel written by Kamachi Kazuma, to be released in parts in the limited editions of the Blu-ray and DVDs of the Toaru Kagaku no Railgun S anime.

The story revolves around the Amakusa-Style Remix of Church being tested by the Church of England to become part of it, but later changes early on with the Amakusa being involved in a conspiracy against the Church and are framed.

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.

Chapter 3
The Amakusa is in the process of healing their injured. There they wonder what they could've transmitted through their sounds, and Itsuwa suggest they analyze the inconsistencies  They deem that the group that attacked the Anglican Church may have done this previously, With this in mind, they need to find out of magicians with records regarding teh Cthulu mythos and the Necronomicon. Seeing this, they need to sneak into an Anglican Church facility to get to some records. Knowing that Necessarius will eventually arrive in the library and take away the bodies of their enemies, Itsuwa has a plan. Basing the model off the Corpse Wax back in the underground, Itsuwa makes a dummy body that looks like Flack Anchors, and enters it. She takes the crystal of the radio that Freadia uses and switches it with their own to allow her to communicate with the other Amakusa.

With that, Freadia comes to and discovers that she has been treated. She begins to doubt Amakusa's role but still suspects them. She orders the personnel to take the bodies of Flack and his comrades to the Sword Sanctuary facility in order to find out their goals, despite the facility being inadequate for the task. As a person there tries to open up Flack, Itsuwa bursts out of it and knocks him unconscious. After she ties him, she goes to its "morgues," a large room where they keep records. With time of the essence, Itsuwa searches for anything related to the Cthulhu Mythos and the Necronomicon. Here, she discovers incidents that are vaguely related to the tales of the Mythos, but one incident strikes out the most. An incident in the Atlantic where the American crew all went insane, a bizarre ritual to call upon the underwater dead city of R'lyeh where the Great Old One Chulhu sleeps. It was merely an attempt to gain inspiration for their magical research, and the main culprit of this was a man named Arlands Darkstreet of the magica cabal Dusk Waiting to Awaken.

Meanwhile, Freadia discovers that her crystal is a fake, and discovers the tied up body of her comrade. Rallying him and the personnel there, she goes to the room of records. Itsuwa is aware of this as well for she felt pain in her temples, an indication that the crystal radio they used for their communication has been discovered. As the personnel tries to bust into the room, Itsuwa sets up a trick with a Mandala, an illusion spell upon a desk to confuse Freadia. And from there, Itsuwa injures herself in order to force them to heal her in order for her to get her crystal back. When the Necessarius personnel enters they find Itsuwa's unconscious body. Freadia falls for the illusoin magic, believing it to be her crystal which she cannot get back, and since it is cursed, she is forced to take care of Itsuwa until she wakes up in order to get the information she needs to get her crystal back.

When Itsuwa comes to, she finds herself strapped on a bed with Freadia on top. Itsuwa easily tells her where the real crystal (in Itsuwa's pants pocke) is and how she was fooled thorugh the Mandala spell. Freadia reminds her that she is no longer of use, but Itsuwa convinces her of the logical inconsistencies of their apparent guilt, and tells her of Arlands Darkstreet. Hearing this, Freadia acquiesces to believe her, but she is forces Itsuwa to wear a collar in order for her to not be able to escape.

As they sneak away to leave and enter commandeer a vehicle, Freadia shows her distrust of Itsuwa once more, and plans to kill her outside as killing her in the Sword Sanctuary when she was defenceless would cause too much problems. However, the Amakusa girl has reveals a trick up her sleeve and escapes into a sewer, with the other Amakusa waiting for her. Freadia tries to make pursuit and kill Itsuwa with the cursed collar but is once again fooled by the Amakusa. She looks down on the strange markings down the manhole and sees that it is similar to the Mandala spell from before. There she believes that the Amakusa might've analyzed her crystal while she was unconscious and that if she uses the crystal radio the spell might backfire on her.

In the sewers, the collar on Itsuwa's neck is destroyed, and there they begin to hunt down Arlands Darkstreet and the Dusk Waiting to Awaken.

Chapter 4
The Amakusa come out of the sewers that drain into the Thames. Here, they ponder on where to find Arlands Darkstreet, but with a little engenuity, Saiji figures out. Using a computer found in modern cars, he searches on the Internet indications of Arland's presence and finds a company that is doing salvage work for sunken ships in the Strait of Dover. They doubt why the Dusk Waiting to Awaken would choose the Strait of Dover to summon R’lyeh instead of the Pacific as stated in the tales of the Cthulhu Mythos, but they have no time to ponder on this matter, as Arlands Darkstreet begins going to his destination. The Amakusa decide to climb onboard a passing cargo ship instead of using their paper boat magic as they are still in London and the Anglican Church still sees all. Here, Itsuwa questions the mindset of Arlands for wanting to summon R'lyeh, to which Saiji says that all magicians have differing motivations, some just want to have fun and they will do whatever they can to attain it.

In a helicopter, Arlands instruct his subordinates, Dodge, Vase, and Rotia to begin preparations as he is heading to the float where the salvage operation is occurring. Though they are worried about their pursuers, they are confident all is going according to plan. Arlands then instruct them to prepare the pawns who will read the Necronomicon for them. He arrives at the float and tosses the Necronomicon to Dodge and orders him to begin preparing with their pawns. He inquires about the glass that would reflect the light used there to make the float look like it was beyond Euclidean geometry just like the R’lyeh in the story. After meeting an unsuspecting worker from the float, he locks himself in a room, takes out a bottle of human blood and flesh, and begins writing symbols in the room.

The Amakusa arrive on the cold waters of Dover Strait using fireboats to attack the float while they use the other paper boats for transportation. After sighting the float explosions rock their progress, and here they discover that the magic cabal is trying to emulate the earthquakes found in the story that was a prelude to the raising of R’lyeh. After the ships arrive and exploded upon the float, they too reach the float, which was now in flames. After a while, the ground they tread upon resembled  a pulsing blood vessel ran across the steel surface of the float. Moreover, Tsushima sees the strong lights used in the float in the otherwise dark night, giving the illusion where that the place has strange shapes that cannot be represented by Euclidean geometry. Here, they discover that they weren't trying to summon R'lyeh from the deaths but make it so that the float was R'lyeh itself. Itsuwa tells the rest of them to destroy the lights that allow this magic ritual to become reality. Suddenly however, something strokes her back, coming from the murky depths of the waters below her. Many tentacles have appeared, that of the Great Old One Cthulhu. Itsuwa collapsed and the tentacles vanish later as Saiji says that it was more of a mental presence than a physical one, though for now. With time of the essence Tsushima asks how to get Itsuwa back from the nightmare that the Great Old One Cthulhu is sending to her. Saiji says that though difficult, they need to analyze on how Cthulhu is sending its presence to Itsuwa and then send their own meaningless information to dilute it, allowing them to free Itsuwa. Suddenly a shadow passes over them, a giant mass silhoutted by the bright lights. The Amakusa were in danger into succumbing like Itsuwa if they focus on it.

Meanwhile, Arlands is in he room meditating, the mental efforts to keep the ritual he's doing taking a toll on him. Nevertheless, he is enjoying all the same. Suddenly, he is to the side and Itsuwa appears. Arlands try to inquire on how she managed to escape, to which Itsuwa says that since the evil gods of the Mythos gain their role and terror from the story they represent, then they can escape if they give out an ending for the gods. That is, the illusion that the "intruders", the Amakusa, were defeated and its conclusion drove Cthulhu away. To do this, they need only to mess with the method on how Arlands twisted the float. Arlands is amused, and then, after burdening with the ritual collapses down.

Itsuwa communicates with Saiji on how she is finished here. However, she notices something on the wall and felt a part of it with her hands. Using her spear she rips up the wallpaper and discovers symbols behind them, a communocation spell. Itsuwa discovers that their aim wasn't the Cthulhu Mythos, they were just researching the margin of error that allows a spell to function even when it leaves the proper formula. Itsuwa realizes that they wanted to freely interfere with existing legends and myths and rearrange them as they wished. Itsuwa tells Saiji to leave right away to Stonehenge as the experimental data that was made on the float was sent there.

Meanwhile, Vase arrives at Stonehenge carrying a long sheet of parchment made up of human flesh with a mysterious young man. They discuss the fate of Arlands, who enjoyed himself till the very end. After reading the report written on the parchment, the two of them go to Stonehenge to being the Blank Paper spell.

Chapter 5
Vase and the other members of the the Dusk Waiting to Awaken are in Stonehenge preparing to use to create the Blank Paper spell. With them are tents of various focus groups interested in the old relic but have nothing to do with magic or the Church. However, there are Anglicans there, and with their plan in motion, they kill the Anglican members one by one, though knowing that they'll be there soon.

Still reeling from the embarassing escape of the Amakusa from her hands in the Sword Sanctuary, Freadia is determined to catch them, believing them to be the culprit of the incidents that have happened. She knows of how they have went to Strait of Dover but opts to intercept them only in Stonehenge. She asks the one who manages the place to give her a special armor to increase her power. He hesitates for it shall weaken her body considerably after using, but Freadia is insistent. Thinking that she will just kill him just to get the armor anyway, he reluctantly gives it to her and head to Stonehenge.

The Amakusa arrive at Stonehenge, and a few scout out the premises before engaging the magic cabal. However, they are quickly detected. Seeing this, the Amakusa quickly mobilize, moving symbolically through the encampments to make the people believe they are animals. They find the members of the magic cabal and engaged in battle against them. They use magic based on the edritch tales found in the Cthulhu Mythos, and Itsuwa easily defeats a few of them. However, they come upon Vase and his Shining Trapezohedron, and with a single clutch of it in his hand, darkens it from all light, allowing him to summon dark clouds and lightning to try to engulf them, the form that great Nyarlathotep took in one of the tales. Thinking quickly, Itsuwa charms her spear with the legend of St. Andrew as so she can throw it towards Vase. The spear absorbs the lightning that hits it, and easily hits his hand carrying the stone. He fumbles and the trapezohedron flies through to the air from his hands, ending the engulfing clouds. However, to everyone's horror, Vase opted to do the unthinkable, He opens his mouth and swallows the jewel. In total darkness, Stonehenge is engulfed in darkness.

Freadia however arrives and easily knocks out everyone including Vase, ending the engulfing darkness. Itsuwa finds her bearings and notices the armored woman before her, Freadia Strikers with no expression came at Itsuwa and has already hit by one of her attacks, weakening her. Itsuwa on the other hand still under the effects of the previous battle insead takes up Tsushima's sword instead. She forms a circle and figures out the weaknesses of the armor and how to stop her. Saiji regains consciousness just barely to call out to Freadia to distract her. Itsuwa charges, wanting to target the joints of the armor to cut it open and destroy it without killing Freadia. However, as she stepped forward the curse that Freadia had put upon her as already spread and she falls without being able to attack. Freadia still with no expression, attacks the weakened Itsuwa with those same curses again and again. And thus the incident in Stonehenge is resolved.

The Amakusa and the Dusk Waiting to Awaken are later chucked into a single truck to be driven to the Tower of London to await torture. Itsuwa comes to and finds that they are guarded by Anglican magicians, Freadia is there as well, removing the armor. Seeing that, Itsuwa sees the toll tha Freadia had to pay for wearing it. Itsuwa and Freadia do a little banter with one another with the former confident that even if they get tortured the Anglican Church will eventually find that they were innocent. Their conversation ends with their truck hewn in half by a mysterious man with a sword, with the contents being the Amakusa and the Dusk Waiting to Awaken, strewn all over the English countryside. Freadia is still adamant that the Amakusa has come to rescue her and his comrades, and Itsuwa also believes it to be either the Dusk Waiting to Awaken or the Anglican Church attacking it to hide the embarassment of the recent incidents with them. She however, quickly change her mind. Hiding behind a bush, Itsuwa finds that the culprit is a new player in this conspiracy, and is seemingly trying to find a target, searching the place for a certain someone. The person gathers the people into a single spot, and Freadia concludes that they are to be executed. Itsuwa then concludes that the most likely target would be Freadia, and seeing the execution of her comrades, Anglicans, a about to take place, pleads with Freadia to aid her in stopping him.

Chapter 6
The assailant calls out to them for she does not know where they are in this dark field in the countryside. Knowing this, she warns that if they do not show themselves, or more specifically, if Freadia does not show herself, she will kill her hostages one by one. Itsuwa knows that she cannot see them, and ignored her demands. She crawls towards Freadia for she still had the curse imposed upon her. who is concerned that the assailant is looking at them, but Itsuwa says that she would not be shouting if she did. Itsuwa crawls towards a fallen container that have been sliced from the truck that once carried them. There, Itsuwa took away a knapsack from the Anglicans that containing a variety of tools likely used for ceremonies, though nothing to break the curse and she dounts Freadia will her from it. Using the telescope, Itsuwa sees that there are 80-100 hostages counting the Amakusas, Dusk Waiting to Awaken, and he Anglicans, sitting in a line along the road. Freadia says she doesn't see how a single person can monitor a hundred people, to which Itsuwa says it would do no good for them to scatter for the magician's reach is too great and that there are little cover, they will surely be cut down by her. After describing the magician's appearance to Freadia, they begin to analyze her magic. Itsuwa focused on the magician's scabbard. The woman had with her a combination lock affixed on her scabbard. Then the magician woman with the sword moved. Believing they were spotted, Itsuwa lied down low. However, much to her horror she discovers that the magician had lost her patience and has begun threatening hostages. She takes Tsushima and warns them again, much to Itsuwa's despair. With no way to save Tsushima, she swallows her terror and begins talking to Freadia.

Itsuwa argues with Freadia on the fate of the hostages, in which Itsuwa points on how they will not stand a chance in a straight fight and that their only hope is to determine what kind of spell the woman has and forced it to go out of control. Freadia states that they have no time to analyze the spell as the woman will start killing soon. However, as Freadia tried to stand, Itsuwa says that if they failed here they would not be able to save any of them. Itsuwa points out that the only way to save everyone was to analyze the magician's spell and that there were no reason for the magician to spare anyone if they go along with her demands. She warns her that if she tries to surrender to save the hostages then she will kill her herself. Freadia asks about the first hostage the woman brought out, leading to Itsuwa to say bitterly that there is now way to save her. With Itsuwa's pleadings Freadia finally agrees with a nod. Itsuwa uses the telescope to scope the magician's movements even if the magician begins her torture of Tsushima, while Freadia analyzes the cut of the sword the magician used. She then pulls out tools from within her clothes that are often used for jewelry appraisal, though she uses crystals for her spell it is only natural. While Freadia moves away to check on the cuts, Itsuwa is forced to watch the horrific torture of her friend Tsushima, all the while trying to find any information she can muster. Then she notices the dials on the woman's scabbard being moved by her, and then pulling out a blade that could not possibly fit in the scabbard. Then the magician begins stabbing Tsushima, much to Itsuwa's despair. The woman then spins the dials again and pulls out a axe out of her sword scabbard. There, Itsuwa understood that the properties of the blade change base on the dials, though she doesn't know from where the magic is based from. However, that information isn't enough for a counterattack, and Itsuwa can only watch in horror while the magician cuts down Tsushima's leg. Freadia returns later and states that the cut of the sword is related to jewels just like her specialty. Itsuwa asks about the dials, to which Freadia states that what matter is where the stone is located as its location would be directly linked to the blade's attack power. She says that the dials likely contain small stones arranged like a gear and that the numbers aren't what matter but by spinning the dials, the arrangement is changed and the stone with the wanted properties is created. The sword's properties, she says, would then change based on the changes to the stone. Itsuwa then asks of its format, as she panics, though Freadia could only say that it is of Wester European origin on account of the magician's appearance, much to Itsuwa's dismay. Freadia however, answers that the fact that they don't have a single answer is an answer in and of itself, and then she smiles. She tells of legends swords and the jewels attached to it, on how if someone is injured by a certain sword then they can never be healed unless the wound is scraped by the jewel attached to the sword's hilt. She states that the sword that injures and the stone that heals form a set, as such, if Itsuwa remembers the combination of the dials that was used to cause injury, then can surely heal wounds if they have it strike the one who as injured by the sword again. Freadia says that since the sword's properties are based in the stone created by the dials then adding something extra in the cycle woud cause her to lose control of the spiritual item.

Meanwhile, seeing as Freadia, the girl's target, has not come out of the shadows, she opts to use another hostage in order for her (them) not to get used to screaming and become complancent. She then however notices a rustling upon the grass: Freadia has shown herself. This is not in Itsuwa's plans however, as she believed she could've used the blank parchment she found earlier to draw a Mandala, scatter it to the wind, and sending her sword out of control. She wonders why Freadia stepped into danger even knowing that she still had an advantage on Itsuwa. Thus, Freadia faces off against the mysterious magician from fifty meters away, with her thoughts on Itsuwa's plan, though decent was still likely to fail. The magician pulls out her sword again, this time the same one that cut down the trucks in the first place. As the blade slices towards Freadia, she holds out her hand with crystral radio components and the Trapezohedron that Vase coughed up after being detained. The cut struck her hodge-podge. Here, in accordance with the principles of the legends of stones and the sword being connected in spite of being physically apart, her more powerful and conductive method (direct contact with the Trapezohedron) interfered with the stone, overwriting it and turning it into a the form of a Trapezohedron. The effect was the sword that was produced from the trapezohedron qualify as healing. The blade grew pitch black explosion and evenly attacked all nearby forms of life, throwing both Freadia and the magician into the air. Freadia smiles, contented that she had defeated a sinner.

With the Amakusas freed, Itsuwa instructs Saiji the combination of the dial in order for them to heal Tsushima. Itsuwa comes towards Freadia, still quite conscious, though portions of her body was covered in black, which is doubtful that it can be healed from the sword as her injuries were derived from an extraordinary situation. Freadia mentions that the magician is likely to have the same injuries as well, and mentions that if she can get back to an Anglican cathedral, she can have the injuries, her curse, on her body broken. Isahaya and Ushibuka then arrives, with Itsuwa leaning on him for support while the latter carries Freadia. Isahaya explains that the others are looking through the destroyed trucks and that they are trying to salvage a working spiritual itme for communication. Saiji, after treating Tsushima, tosses Itsuwa the ID from the attacker. The magician's name is Emilie Fordia, and her nationality was a country near the equator in the Pacific Ocean that uses pound as a currency. Itsuwa then asks if Freadia have any ideas. Here, Freadia realizes something from when she put on the armor from the Sword Sanctuary, on how her colleague needed her to help in the construction of a security arrangement for the summit of the pound economy leaders. As a planner for security, she is supposed to look into detailed information with the VIPs even with some secrets that they do not want to be discovered. Here, she realizes that Emilie wasn't attempting to get information out of her for use in assassinating a VIP of the pound economy but kill her outright. This means Emilie attacked not to gather information but to eliminate it. Here, she discovers the one behind the attac was from the pound economy.

News of the attack traveled fast with Prime Minister Aili Hexenphobia, a figurehead leader of a pound economy country, figuring out that Emilie had failed in her mission, despite taking advantage of the situation surrounding the Dusk Waiting to Awaken to attack Freadia. And news of her failure reached other ears as well as the Anglican Church has arrived to take her away for questioning, and entering her room. Aili makes no attempt to hide her involvement, apparently believing already victorious. She points out on how her country is still not free despite being "independent" from England, as the ley lines and other veins of magical energy are still artificially altered, and still being used by the Church to draw energy in order to spread their influence. As such, she states that she will destroy the magical foundation of England. At that moment, the entire room was covered in duralumin, originating from the attaché case in a corner of the room opening, slowing down the magicians present there from doing anything. Aili mentions the legend of St. George and how the spell is related to it, with St. George having God destroy the Romans' priests and temples destroyed with something like a meteor. Aili threatens that the spell would thoroughly destroy every temple, spiritual item, and other magical device in the range of twenty kilometers in every direction. The target was London, and the spell would essentially make the city a magical vacuum. Thus Aili boasts to them on how they have already failed, and she needs only to wait before the duralumin to uncover her room again to see the fruits of her triumph. Thus there was a silence in that room while they wait for the duralumin barrier to end. However, as it does so, Aili is horrified to discover that the city is still intact. Suddenly, there was a ringing of the phone, a fact that the occupants of the room thought queer, especially Aili, who only uses communication spiritual items with everyone within her group. Tension spread through the room even to the Anglican magicians there as Aili answered the phone. There, Aili discovers something terrible, someone said to Aili that their country's magical foundation have been destroyed. The person on the phone then asks if her country was okay. Upon hearing this Aili grew pale, as she discovers that the spell was swapped out to use they ley line connections and destroy pound economy countries instead.

Meanwhile, the party responsible, the one who "sold" the St. George-derived spell, notes on how the pound economy now not being able to function has reduced England's influence. And thus they begin their preparations in their final battle with England.
