"Book of the Law" (法の書 Hō no Sho?) is the second episode of the second season of the Toaru Majutsu no Index anime adaption and the twenty-sixth episode overall. It was first aired on October 15, 2010.
On the streets of London, an unlikely scene unfolds: The Archbishop of Necessarius, Laura Stuart, goes out for a stroll with Stiyl Magnus. Laura insists on going on despite her status and Stiyl's bickering around about it, and in the middle of their conversation, has her "unusual" Japanese commented harshly by Stiyl. She feels uncomfortable at the remark, and assumes that the Japanese she learned from Tsuchimikado Motoharu is the usual manner of speaking; Stiyl dispels that assumption and tells her to avoid basing him for a normal Japanese citizen.
Soon, Laura switches to a magical form of communication using amulets, and as they walk along, she opens the topic about "The Book of the Law", a person named Orsola Aquinas, and their involvement with the Amakusa Christians, a Japanese religious sect.
Upon reaching St. George's Cathedral, they head inside and discuss further on the issue.
Meanwhile, the second of the three-trimester schedule of classes in Academy City begins.
Because of the hectic schedules, Index is left alone in Touma's apartment. Fortunately, Tsuchimikado Maika is there as well, doing her usual chores as a maid school student. Index discovers from Maika how a maid can go around without hassles and blurts out that she wants to become one as well; however, Maika reminds her that being a maid is never an easy job.
As the two girls converse, a man with red hair and wearing a black robe appears behind Index: Stiyl Magnus.
Touma, on the other hand, finds himself unfamiliar to the upcoming Daihaseisai as a result of having his memories erased in a previous event, and goes home like always. There, he saws a distressed Maika waving at him. There, Maika explains what happened to her companion Index and who was her abductor, and gives a small envelope containing a letter telling Touma to go to Hakumeiza at 7 pm. Upon guessing who kidnapped Index, Touma shrugs it off, as that person is familiar to Index. Soon, another slip of paper fell from the envelope, and it contains a permit for exiting Academy City.
Stiyl and Index talk at the meeting place, and after listening to Stiyl's explanation, Index understands what is going on. As it turns out, Stiyl is asked to return to Japan by Laura Stuart and resolve the issue regarding "The Book of the Law" and Kanzaki Kaori, who has gone missing (and is suspected to switch sides). Also, she wants Index involved as well. However, Index is still puzzled as to why Touma must be involved as well.
Soon, a nun joins them; a girl with braided hair, a short nun's robe, and shoes with tall soles.
Touma decides to head outside Academy City to look for Stiyl; upon his search for Hakumeiza, he sees a woman dressed in black nun's clothing. That woman sees Touma and begins to ask for ways to go to Academy City. Touma explains that there are no means of travel into Academy City, but the confused nun has a hard time understanding what he's trying to say.
The nun decides to stay with Touma longer and there, Touma asks her about her intents on going to Academy City. She answers that she is pursued.
At Hakumeiza, the stranger that joins Stiyl and Index introduces herself as Agnese Sanctis from the Roman Catholic Church, and admits that they are in a dire situation, not knowing how their enemy--the Amakusa--work. Index tells Agnese that the Amakusa are masters in subtlety, their powerful spells disguised in the least likely of places. Soon, Index notices Touma going their way, and Agnese notices someone familiar with him: Orsola Aquinas.
Touma finally meets up with Stiyl and demands an explanation from him. However, Stiyl strongly rejects his demand and instead, asks him to bring Orsola Aquinas--Touma's companion on the way--to their custody. The topic shifts to Stiyl's rudeness against Touma, and back to Orsola, who discovers that she is in front of the same person she has been trying to run away from.
Then suddenly, a voice came out of a ball floating in mid-air, telling them about Orsola living more meaningfully on his custody. Orsola then falls into a triangular hole made by sword that pierce through the concrete, and Touma tries to follow her down, only to be stopped by Index, who sees three men armed with swords below the hole. Stiyl tries to fight back as well, but he no longer feels any presence inside the hole.
Touma looks to Stiyl for any explanation on what's going on, but even Stiyl admits that he wants things explained as well.
That night, Agnese calls the nuns under her command while Index explains on the extent of power of "The Book of the Law". Stiyl also adds that it is capable of ending the world ruled by Christianity. Touma suggests burning the book, but Index tells him that magical books do not burn, and can only be sealed.
They are then joined by Agnese, who loses her balance and drags Touma in an indecent situation the moment she was to start. After receiving a kick from Stiyl for screwing up, Touma goes to listen Agnese with Stiyl and Index. Index judges that Agnese still has little information regarding the Amakusa and suggests that they might use "miniaturized pilgrimage"--a magical transportation technique based on a certain map-- to escape their pursuers. Despite this, Index assures that it can only be done at midnight, meaning that they still have four hours to prepare. Meanwhile, she uses the GPS function in Touma's phone to plot the location of the nearest portal.
For the meantime, they can only rest until the time comes.
As some of the nuns set up their tents, Touma walks around and realizes the tension involved with being a nun. He soon arrives at a tent filled with runes, which he assumes are Stiyl's runes protecting Index's tent, and sees that it's empty. Soon, he hears a scream from one of the larger tents. Alarmed that it might be Amakusa, he rushes to help, but instead finds an naked Agnese clinging to him. Agnese mutters something about a slug and faints, while Touma realizes that Index is bathing with Agnese, and finds the silver-haired nun in tears. Touma tries to calm her down, and the situation ends with Index gnashing her teeth on Touma's head.
Touma retires to a tent with Stiyl watching him. There, Touma asks Stiyl about the girl she likes after having two girls involved with the fire mage (Index and Kanzaki Kaori) on opposing sides. Stiyl tells Touma that he has decided, that he has vowed to protect Index no matter what it takes.
With that, Stiyl tells him to go to sleep.
Touma soon wakes up and finds someone creeping inside his blanket. He assumes that it was Index, but instead, he sees Index on the entrance to the tent and a scantily-clothed Agnese just inches from his face. Index, half-asleep, mutters about returning her frustrations and gives another bite at Touma.
Meanwhile, at Parallel Sweets Park, a man wearing a white shirt with a red cross design and unkempt black hair watches as Orsola is bound behind him. A girlreportsto him about the completion of preparations for the miniaturized pilgrimage.

Even if it means putting my life on the line." -said to Touma regarding his question if he would still fight knowing Kaori might become an enemy.
