| At night in Academy City, Toma Kamijo meets the third most powerful Level 5 esper Mikoto Misaka at a bridge after saving her from delinquents inside a restaurant. The following morning, Toma finds a hungry nun hanging on his dormitory's balcony. She introduces herself as Index from the Church of England. Index and Toma then engage in a debate about the existence of magic and his right hand's power called "Imagine Breaker" which can negate any supernatural abilities. Afterward, Index leaves as she is being pursued by magicians seeking the 103,000 grimoires in her head. After attending his supplementary lessons and encountering Mikoto again, Toma finds a wounded Index in front of his room when magician Stiyl Magnus showed up to retrieve her. Stiyl finds his magic attacks useless against Toma's Imagine Breaker and summons a fiery creature called "Innocentius". Toma manages to defeat Stiyl after destroying the runes surrounding the dormitory's floor, which keeps the creature alive. He later brings Index to his homeroom teacher Komoe Tsukuyomi for assistance in healing her. The next day, a recovering Index introduces Toma to her religion. |||||

| While heading to a public bath with Index, Toma meets magician Kaori Kanzaki. As the two fight, Kaori reveals that she and Stiyl are friends with Index and how her memory is being erased every year to protect the grimoires in her head. Three days after the battle, an injured Toma wakes up back inside Komoe's apartment with Index taking care of him and panics since he learns from Kaori that Index's memories need to be erased today. Afterward, Stiyl and Kaori arrive to prepare the ceremony required for the erasure of Index's memories. Toma left them and calls Komoe for information about memory capacity since he also learns that Index can only use 15% of her brain for unwanted memories while the remaining 85% is reserved for the grimoires. Komoe tells him that a human brain can store a huge amount of information for up to 140 years. With the newfound knowledge, Toma rushes back into the apartment and convinces the two magicians to give him time in saying a farewell message to Index. He then finds a hidden spell to be the cause of her predicament in her throat and negates it using the Imagine Breaker, resulting in her activating her defense mechanism called "John's Pen". A fight between the two ensues until Toma manages to save Index with the help of Stiyl and Kaori. The after-effect of John's Pen called "Feather of Light" causes Toma's memories to be erased instead, subsequently knocking him down. In a hospital the following day, Index visits Toma upon hearing about his memory loss. He chooses to hide it from her. |||||

Toma then calls Komoe for information about Hyōka and learns that she is an artificial human created by esper's AIM diffusion fields. Toma still decides to save her as a friend and seeks assistance from nearby Anti-Skills led by Aiho Yomikawa. As Sherry attacks and scolds Hyōka for being a monster, Toma arrives with Anti-Skills to save her. He manages to knock Sherry down but she escapes from him. Toma deduces that she plans on targeting Index next but is unable to leave the underground mall due to the lowered security shutter doors. Hyōka then decides to pursue Sherry instead through the hole the latter created earlier during the escape. Index arrives at a construction site while pursuing Sphynx and suddenly gets attacked by Sherry's golem. Index manages to evade its attacks using Spell Intercept but struggles to defeat it.

| Saiji further reveals that Orsola finds the Roman Catholic Church hard to live in since they see her as a threat for being the Book of Law's decoder. He explains that the Amakusa Church wants to follow their former priestess Kaori's good examples by helping Orsola. Toma hears Orsola's scream but is prevented by Sisters Lucia and Angelene from seeing her. A fight between them ensues until the two sisters retreat upon orders. Saiji plans on rescuing both Orsola and his captured comrades. After entrusting him with Orsola's safety, Toma, Index, and Stiyl head back to Academy City, but Toma still decides to charge in a church where the Roman Catholic nuns torture Orsola. As Toma is surrounded by the nuns, Index, Stiyl, Saiji, and his Amakusa Catholics arrive. A battle follows while Toma carries Orsola to safety. Meanwhile, Index uses her ability called "Sheol Fear" against the nuns, which can break down their minds upon hearing it, but they counter-attack the power by jabbing their ears.

While dining with Index and Orsola, Toma meets a member of the Amakusa Church named Itsuwa. After helping pack up Orsola's belongings for her move to London, Toma and Index part ways with Orsola when they are suddenly attacked by the Roman Catholics. They manage to defeat the attackers, but Toma and Orsola accidentally board an ice-made ship that suddenly emerges from the canals.

Index explains the trigger for Vento's magic "Divine Punishment" and is instructed by Toma to work with Mikoto, who currently fights several Hound Dogs, to determine the nature behind the angel and the core that controls it. Toma reaches the area where Hyōka is and prevents Vento from attacking her since she sees her as a threat to the Roman Catholic Church. Vento reveals her hatred of science due to the death of her young brother, resulting in her joining God's Right Seat.

Meanwhile, the terrorist named Musset occupies Toma's seat to install an emergency landing jammer near its seat when Index discovers him. Toma saves Index as she is about to get killed by the terrorist in a room close to his. The plane suddenly detects a loss of fuel, which is revealed to be magic by Laura to force an emergency landing in the countryside. Her magic is later interfered with by an unknown organization from Scotland. Toma deduces that there is another terrorist in the plane and finds him in the cargo hold planning to bomb it. The terrorist is later subdued by him with Stiyl's help who arrives on another plane as per Laura's instruction. |||||

| Arriving at an airport in Edinburgh, Toma and Index are picked up by Kaori and brought to Buckingham Palace, where they meet the Knight Leader and Queen Elizard. Elizard introduces Toma to the second replica of the Curtana sword she is wielding and explains how it is related to the three factions in the United Kingdom–Royal, Knights, and Church–that control the country. Toma then meets the Queen's daughters: Riméa, Carissa, and Villian. During the meeting, Elizard orders the Knight Leader and Index to investigate the Eurotunnel incident and Kaori to find the magic cabal that has interfered with Sky Bus 365 emergency landing. Kaori learns from Agnese the involvement of the New Light cabal in the interference and their recent excavation. Carissa orders Toma to join Oriana, who has made a deal with the Anglican Church, in capturing New Light. In London, New Light members Bayloupe, Lessar, and Floris have arrived with each holding a Skíðblaðnir suitcase. Lessar encounters Toma and Oriana, while Bayloupe and Floris are respectively captured by Itsuwa and Kaori. Meanwhile, Agnese deduces with Lucia and Angelene the suitcases' capability to teleport the hidden excavated item between them. She then contacts Toma, who is in the middle of pursuing Lessar, to inform him about the suitcases. Toma manages to capture Lessar, but the latter teleports the hidden item to Lancis, another member of New Light who is currently located outside the city, and also reveals the existence of the fifth suitcase. The Knight Leader, who owns the fifth suitcase, receives the item from Lancis, which turns out to be the original Curtana sword. Carissa wields it and with the backing of the Knights of England, declares a coup d'état against the British monarchy. The Knights of England and the police force in the country begin their operation toward other factions, facing off against the witches, Agnese Forces, and Laura and Elizard. At the Eurotunnel, Carissa mobilizes the country's military force toward France after confirming with Index about the French's involvement in the bombing. |||||
