During their fake date, Tōma learns that only 10 of the Sisters remain at Academy City while the rest went overseas for treatment. Tōma converses with Unabara but is surprised to see another person who looks exactly like the latter running into a restaurant that Mikoto has entered. As the second and injured Unabara warns Mikoto about an approaching danger, the first Unabara remarks to Tōma about espers who can shift appearances, and Tōma realizes that he is conversing with an imposter when the latter tries to hit him from behind. As Tōma flees, Index reveals by phone that the imposter is using the magic of Aztec priests to disguise himself with another person's skin and wields an obsidian spearhead as a replica of the lance of Tlahuizcalpantecuhtli. When Tōma is forced to fight him, the imposter reveals that he had been sent to become close to Tōma's friends (such as Mikoto) to prevent the formation of the "Kamijō Faction", a group of mages and espers lead by Tōma which both the magic and science sides fear will destroy the truce between them. Since the imposter had fallen in love with Mikoto, he decided to protect her by killing Tōma, but, now defeated and severely injured, he asks Tōma to promise him to protect her since they'll be others like him after Tōma and his friends. Unknown to both of them, Mikoto is listening nearby and is embarrassed to hear Tōma's answer.
Last Order (The End)
Since his defeat, Accelerator is no longer feared by others, though he remains powerful enough to get rid of troublemakers. During the last day of summer vacation, he is approached by a younger Misaka clone capable of showing emotions, who introduces herself as "Last Order" and begins to follow him around, much to his annoyance. Because she is hungry, Accelerator takes Last Order to a restaurant and sees Ao Amai, a former researcher for the "The Sisters" project, but does not pursue him. As Last Order eats, she converses with Accelerator on the Sisters and how she believes that Accelerator was an unwilling participant of the Level 6 Shift project. Tired of her comments, Accelerator leaves her at the restaurant to confront Yoshikawa, a researcher in charge of the Level 6 Shift project. She informs him that Last Order was not created for the Sisters project but for administrating the Misaka Network and that Ao Amai injected a virus into Last Order, which could spread to the other Misakas and cause them to go berserk and attack humans. To stop the virus, she gives Accelerator the choice of finding Ao Amai to explain how to stop the virus or returning Last Order to her incubator. Accelerator chooses the latter.

After discussing their roles as researchers and her dream of wanting to become a teacher, she and Amai shoot each other.

He learns that Ellis was once a friend of Sherry who suffered painful consequences from an attempt by Necessarius and Academy City to reconcile magic and science; to prevent this tragedy from occurring again, Sherry intends to divide them forever through conflict. Outraged that Sherry does not believe that people who are different like Index and Hyōka could be friends, Tōma successfully defeats Sherry. However, doing so results in Golem Ellis above ground losing control, and Index is cornered until Hyōka suddenly appears and destroys the Golem each time it reforms.

As Tōma tries to find her, running into Mikoto along the way, Ouma prepares a ceremony that will allow him to access the grimoires inside Index's head in order to find a cure for a curse inflicted on a woman he has fallen in love with. As the ceremony begins, Ouma's body and mind is put through excruciating pain trying to access the grimoires. Thanks to Index using her new cellphone, Tōma is able to find her and stop the ceremony. Tōma gets Ouma to snap out his pitiful state and offers to cure the woman's curse using his Imagine Breaker. Meanwhile, Kanzaki is seen fighting the Knights of England.
The Book of Law
Archbishop Laura informs Stiyl that the Liber AL vel Legis has been stolen by the Amakusa Catholics and sends him to Japan along with a group of Catholic battle nuns known as the Agnese Forces, to search for the grimoire and Orsola Aquinas, the only one who can decode it who was also kidnapped by the Amakusas. In order to get Tōma's assistance, Stiyl pretends to kidnap Index. While Tōma coincidentally runs into Orsola on the way to save Index, the Amakusas appear and abduct her via a hole in the ground. After determining that the Amakusa's goal is to use a special teleport magic to escape with Orsola before midnight, Tōma, Index, Stiyl and the Agnese Forces set up camp at the required location, where Tōma gets into a lot of awkward situations with the group's leader, Agnese Sanctis. Because Kaori was once an Amakusa Catholic, Stiyl knows he may have to fight her if necessary. Meanwhile, the Amakusas prepare to make their move.
The Amakusa Church
The Agnese Forces face off against the Amakusas as a diversion while Tōma, Stiyl and Index sneak inside the amusement park. While escaping from some Amakusa warriors, Tōma manages to find Orsola and gives her a crucifix that Styil gave him earlier. The two are reunited with Stiyl and Index, who are facing against the leader of the Amakusas, Saiji Tatemiya. Working together, Tōma and Stiyl defeat Saiji and the rest of the Amakusas are captured by Agnese's battle nuns. However, the captured Saiji reveals to Tōma and Index that the Amakusas have never stolen the Liber AL vel Legis, as the real reason the Catholic Church wanted Orsola was to kill her to prevent the secrets of the grimoire from being abused. The Amakusas only got involved as Orsola sought them for protection but ran away as she didn't trust them. Troubled by this revelation, Tōma asks two of the Battle Nuns, Luccia and Angelene to see Orsola again but he accidentally angers Luccia who tries to kill him, Index and Saiji. However, she and Angelene are forced to retreat when Index uses spell interception on Angelene's magic and counters Luccia's attack.
Sheol Fear (Voice of the Magicbane)
Stiyl explains that the Catholics won't kill Orsola until they can prove her to be a heretic. As Saiji leaves to free his comrades, Stiyl tells Tōma and Index to go home, since they have no further stake in this matter. Tōma, however, goes by himself to where Orsola is being held and tortured by Agnese's battle nuns, who reveal they deceived Necessarius to assist them. He is later joined by Stiyl, who reveals the crucifix Tōma gave to Orsola means she is under protection of the Church of England, followed by Index and the Amasukas. Whilst Tōma is put in charge in protecting Orsola, the others fend off the battle nuns, with Index utilizing the power "Sheol Fear", to deafen and paralyze some of the battle nuns. However, Luccia brings another force of battle nuns who willingly stab their ears to protect themselves from Sheol Fear.
As Tōma, Index, Stiyl, Saiji and Orsola barricade themselves from the battle nuns, Tōma and Index come up with an idea that Orsola could help them decipher the Liber AL vel Legis in Index's head to their advantage. When Orsola mentions her deciphering method, Index reveals her translations is a fake, revealing Orsola was never able to really decode the grimoire all along. Whilst the others fend off against the battle nuns, Tōma confronts Agnese who attacks him with her Lotus Wand. However, Tōma manages to learn its attack patterns and land a hit on Agnese. As Agnese tries to bluff that Tōma sacrificed his friends as decoys, they arrive with Innocentius, who Stiyl managed to summon thanks to the Amasukas. Her confidence broken, Agnese is knocked out by Tōma, breaking the battle nuns morale, before Tōma himself falls unconscious. Waking up in a hospital in Academy City, Tōma is greeted and taken care by Kaori, who thanks him for helping and tells him that Orsola and the Amasukas are now under the protection of the Church of England. Meanwhile, back in London, Laura reveals to Stiyl that the true reason she got involved with the Orsola incident was to get the Amakusa Catholics under her control and use them as leverage to ensure Kaori's loyalty to Necessarius.
Kuroko's day of shopping with Mikoto is interrupted by reports of robbers stealing an aerospace carrycase. Kuroko subdues the thieves but is then attacked and wounded by their leader, another teleporter named Awaki Musujime. She reveals to Kuroko about Tree Diagram's destruction and how various factions are gathering of its remnants, the contents of the carrycase being one of them. Kuroko manages to escape, but becomes concerned over what Awaki had told her, particularly concerning how Mikoto had been trying to stop them for reasons she had kept from her, (namely being that if Tree Diagram were rebuilt, the Level 6 Shift experiment would start over again). As Mikoto goes out that night to confront Awaki, Kuroko decides to follow her and overhears their conversation before Awaki escapes. As Kuroko decides to take matters into her own hands, Misaka 10032 decides to take action.
Move Point (Coordinate Relocation)
Kuroko finds Awaki at a nearby building and uses the latter's trauma of self-teleportion to make the first strike but during their battle, her injuries make her unable to concentrate on teleporting and she is trapped under a pile of furniture. Awaki explains to Kuroko that she and her organization, the Science Syndicate, plan to build a new Tree Diagram in order to create other species of espers. Awaki tries to persuade Kuroko to join her, believing her powers is a curse that caused her to become how she is. Kuroko rejects her offer, verbally abuses Awaki for making excuses for her own behavior, breaks loose and tries to attack Awaki, but is shot by her. After a brief traumatic loss of control over her powers, Awaki attempts to kill Kuroko by dropping the building on top of her, but she is saved by Mikoto and Tōma, who came to rescue her after he was alerted by Misaka 10032. As the Anti-Skill's stop the Science Syndicate, Awaki tries to escape but to her horror, is confronted by Accelerator who, using the Misaka Network to utilize his powers, defeats her and destroys the Tree Diagram remnant. As everyone recovers, Mikoto gives her thanks to Kuroko.
The Daihasei Festival
Academy City is hosting the Grand Champion Star Festival, a sports competition between the various schools of the city, during which visitors from outside the city are allowed entry. Whilst Tōma's parents, Tōya and Shiina, as well as Misuzu, a relative of Mikoto's, get to know each other, Tōma and Mikoto decide to make a bet in which the loser does anything the winner wants. Meanwhile, Laura contacts Aleister to inform him that magicians have infiltrated Academy City in order to make a transaction with a magical weapon called the Stab Sword, which has the power to kill a Saint. Meanwhile, Tōma has several troubles with a hungry Index and awkward situations with the class representative, Seiri Fukiyose. Later, Tōma runs into Stiyl and Tsuchimikado, who tell him about the intruding magicians and asks him not to get Index involved. Whilst getting scolded by Seiri after an awkward incident with Index and Komoe, Tōma runs into a woman named Oriana Thomson. When his Imagine Breaker reacts to her, he realizes she is one of the magicians in question and starts to follow her.
Route Disturb (Pursuit Inhibited)
As Oriana realizes she's being followed and runs away, Tōma, Stiyl and Tsuchimikado chase her through a bus station filled with booby traps, but she manages to escape and uses a counter magic called Short Hand to avoid being traced. Despite Tōma's objections, Tsuchimikado and Stiyl undergo a painful magical spell in order to locate the Short Hand spell, which happens to be right in the center of a middle school ball throwing tournament. With the competitors in danger of being hurt by the spell if they touch it, Tōma and Tsuchimikado infiltrate the match as contestants in order to find it, only to find the opposing team is Mikoto's school. Tōma tries to protect Mikoto from one of the basket poles which he believes has the Short Hand, only for Seiri to end up touching the real one and gets hit by magic and falls unconscious before Tōma destroys the spell. As Seiri is taken to the hospital, Tōma vows to make Oriana pay on what she did.

Whilst Heaven Canceler attends to Seiri, Stiyl manages to lead Tōma and Tsuchimikado to Oriana's location. Oriana inflicts a curse on Tsuchimikado and gives Tōma trouble with her variety of spells, yet Tōma's determination allows him to land a hit on her. Oriana escapes but leaves behind her cargo, which is later revealed to be a decoy. Laura soon learns that the Stab Sword is actually St. Peter's Cross, which she fears the Catholic Church will use to put Academy City under their control if the trade goes through. After Tōma, Stiyl and Tsuchimikado are informed of this, Tōma has lunch with Index, his parents, Mikoto and Misuzu, and is surprise to learn Misuzu is Mikoto's mother.
After Tōma has some women trouble with Index, Mikoto and Kuroko following lunch, Tsuchimikado manages to find Oriana's location and instructs him and Stiyl to go there. However, whilst Tsuchikimado tries to track Oriana, she goes straight to him and attacks him. She defeats Tsuchikimado and destroys his search spell, but he manages to pull off a bluff that he has summoned reinforcements to trick her into running away before finishing him off. Meanwhile, Aisa becomes worried about Tōma, with Komoe suggesting she should invite him to a night parade at the end of the festival. However, when they bump into Oriana as she makes her escape, she sees Aisa's magic Celtic Cross and mistakes her for a Necessarius magician, attacking her with a vicious spell which leaves her brutally wounded. As Tōma falls into despair upon witnessing her state, Komoe recalls the healing spell she performed on Index, so Stiyl stays to help her perform it whilst Tōma chases after Oriana.

However, Lidvia contacts them and reveals that she and St. Peter's Cross are outside the city and there's nothing they can do to stop her from activating the spell. Luckily, the Night Parade, the festival's fireworks event has started which blocks out the stars and prevents the cross from activating. As Tōma is checked into the hospital, he is visited by Index, Kuroko and Mikoto which the latter informs he has lost their bet. Meanwhile, Lidvia escapes by a private jet but is tracked down by Laura via Stiyl's rune cards and has her ejected out of the plane. Despite Laura offering to save her if she surrenders, Lidvia refuses and chooses to fall to her death while protecting the cross. At the same time, Aleister decides to take action personally due to these recent events. The next morning, Aisa is visited by Index and later, to her joy, Tōma.

Despite a chain of bad luck with his female companions during the festival, Tōma gets lucky on the last day when he wins a lottery for a one week trip to Chioggia, Italy. After he and Index arrive at Chioggia, Tōma tries to find Index after she gets lost but is found by Orsola who manages to find Index. Later, Orsola explains to them that she and the Amakusas are here at Chioggia to help move and pack her belongings to London.

As they hide from their pursuers inside the ship, both of them realize the assassins were from the Catholic church and there is a fleet of Ice ships heading towards the Adriatic Sea.

While Accelerator easily deals with his men, Amata, who had helped Accelerator learn his powers, knows all the tricks to negate his ability and brutally beats him up. When the Hound Dogs attempt to kidnap Last Order, Accelerator manages to muster up enough strength to blow her away to safety, before Index, who wanted to return a tissue package to him appears on the scene. Meanwhile, Tōma goes looking for Index after she went off but witnesses a group of Anti-Skill officers mysteriously falling unconscious before running into Last Order, who asks for his help. At the same time, a magician from God's Right Seat named Vento of the Front has entered Academy City and contacts Aleister that she has neutralize the Anti-Skill and Judgment forces, killed three of his Board of Directors and is planning to kill him and everyone else in Academy City.

Hound Dog (Hound Squad)
Accelerator uses Index's presence as a distraction to force a driver to get him and Index away from the Hound Dogs. Before Amata can go after them, Vento appears and takes care of his men as he pursues after Accelerator. Meanwhile, as Tōma and Last Order search for Accelerator, they escape from the Hound Dogs chasing after her by hiding in a restaurant where everyone is also unconscious. Accelerator leaves Index in the care of Heaven Canceller, who informs him about Last Order's situation. In an attempt to take out the Hound Dogs hunting him, he lures them into a railway factory and kills them off one by one. As Tōma and Last Order continue to hide, they are confronted by Vento, whose image has caused several people, including Aiho and Kazari, to fall unconscious. Tōma defends the unconscious patrons of the restaurant from Vento's attacks and tells Last Order to run as Vento is after him but she soon starts coughing up blood and is forced to flee. Accelerator finally kills the last Hound Dog soldier hunting him but his actions have been witness by an Anti-Skill patrol unit, putting him as a wanted murder suspect. Meanwhile, Tsuchimikado is investigating Vento's actions, and comes across a white spectral being.
Testament (Learning Device)
As Tsuchimikado battles against the spectral being who is working with Vento to kill the unconscious residents of Academy City, Tōma calls Accelerator from Last Order's cellphone to update him on her status. Accelerator soon learns that Amata has managed to capture Last Order, though is keeping her alive for some reason. Aleister then uses Testament, with Last Order's authorization, to summon an angel to appear in the city to target those who use magic. As Tōma, Mikoto and Index head towards where the angel is, Index realizes the angel is actually Hyōka. As Mikoto holds off the Hound Dogs, Index explains the nature of Vento's Divine Punishment, which targets anyone who experiences a certain emotion towards her and how Hyōka isn't an ordinary angel. Tōma tells her to work with Mikoto to combine their knowledge of magic and science to figure out how to help her. Meanwhile, Accelerator breaks into the Hound Dog's headquarters and confronts Amata. As Tōma witnesses Hyōka's controlled state and feels helpless, since using his right hand would kill her, Vento appears before him again, threatening to kill them both, so Tōma stands to defend Hyōka.

Accelerator starts to fight Amata, but the battery for his link to the Misaka Network runs out, leaving him paralyzed and defenseless. However, he begins to move again by force of will and starts to come after Amata. Meanwhile, Tōma fights against Vento, who continues to be weakened by Testament, while Hyōka makes snow appear over the city, protecting the unconscious civilians. Vento reveals her hatred towards science because both she and her little brother got into accident at a amusement park that was supposed to be the safest and the hospital only had enough blood to save her alone. Tōma argues against her reasoning for her actions and manages to punch and knock her out. Index appears in Amata's HQ and, thanks to Mikoto's knowledge of science, learns that Last Order is being used as a container to create the angel. She sings a song in order to sever the shackles controlling Last Order, which in turn resonates with Accelerator who awakens as a result and blasts Amata into the sky. In the end, Acqua of the Back from God's Right Seat appears and gives Tōma Vento's cross as her Divine Punishment has been dispelled before warning Tōma not to fight him as he is a Saint and leaves with Vento.
Thanks to Index, Hyōka returns to normal and, despite blaming herself for the chaos she caused, Tōma ensures her she also protected the city's populace. As Acqua retreats with Vento and the rest of her men from Academy City, Accelerator is captured by the City's security forces. As the city recovers from Vento's attack, Tsuchimikado and Tōma's class have dinner at a sukiyaki restaurant where they later talk about how a war will be coming to Academy City.

However, Accelerator manages to use a pistol to clear the air and land a shot on him, thanks to Awaki's assistance. After killing Ritoku, Accelerator decides to do some overtime and encounters a drunk Misuzu, who is searching for the Dangai University database center for a report. After sending her off in a taxi, where she exchanges numbers with Tōma, Accelerator is contacted by GROUP's mysterious head, who reveals that they have hired the Skill-Outs to kill Misuzu as she is the Parent-Student representative who are attempting to take their children out of Academy City before the impending war. When they cut off his powers after he refuses to help the Skill-Outs, Accelerator decides to head to Dangai University to rescue Misuzu despite spotting Tōma, who also goes there to save Misuzu after she called him for help. Thanks to Accelerator's unseen aid, Tōma is able to escape with Misuzu from the Skill-Outs, only to confront by one of them named Shiage Hamazura.
