Unified Story Timeline

The lists events in the Toaru Majutsu no Index universe in chronological order. This timeline tries to harmonize the events from all the mediums that tell the stories of the Toaru Majutsu no Index universe, so long as they are canon, things that happen in the story as it goes, things that have come to pass or mentioned in passing, and things that may. This bars video games, parodies, and audio dramas unless their time frames can be determined. Discrepancies will surely abound, but this is the fate of a franchise that has spanned greatly in several media and in the hands of several people.

December 10

 * After getting Mikoto to Heaven Canceller's hospital, Touma's group decide to set off a delayed explosion at Useful Spider's base in District 21 to draw their forces away from District 11 so they could access the A.A.A.'s core. Due to Useful Spider's actions, the Kamisato Faction see them as an obstacle and also target their base. During the battle at the base, Fran's nature as a magician and spy from the Anglican Church is revealed.
 * Escaping from District 21, Fran and Luca move to cast the spell to rescue Kamisato Kakeru from the 'new world'. After the initial attempt with the A.A.A. is thwarted by Maya, the group manages to fend off the pursuing Kamisato Faction and use the part of Nephthys inside Patricia Birdway to carry out the retrieval spell.

December 11

 * The Kamisato Rescue Arc concludes.
 * Useful Spider declares the end of '48 Hours to Restore Order'. Residents leave the shelters and run to their homes as normal activities resume in Academy City.
 * Fran is confronted by Aleister Crowley. Before she can be abducted, Aleister is shot by Tsuchimikado Motoharu for not fulfilling his promise to protect Maika. With Aleister not dead, the two decide to go to Touma and use him as a shield to protect themselves from Aleister.
 * The Aleister Crowley Arc occurs.
 * Touma accompanies the Tsuchimikados and Fran in their attempt to escape Academy City, however Maika is pierced by a cursed shadow sword at the wall, which summons chain beasts bearing Karma to their position and forces them to break into the Windowless Building and face Aleister to find a way to remove it.
 * After the group enter the Windowless Building, Touma is split up from the others. As he ascends the Windowless Building, he is shown a series of visions detailing Aleister's past, guided through them by a recreation of Mina Mathers by the Reading Thoth 78.
 * Meanwhile, Misaka Mikoto reanalyzes the original Anti-Art Attachment with Shokuhou Misaki's help. After determining that it is connected to the Board Chairman, who is focused on and facing Touma, the two cooperate and manage to penetrate the Windowless Building's walls with the Liquid Proof Railgun.
 * Touma faces Aleister in battle, during which he summons Aiwass as part of a ceremony to destroy the phases. Due to the intervention of the Reading Thoth 78, as well as Mikoto's attack on the building and the group's dispelling of the shadow sword, Aiwass disappears and Touma is able to knock out Aleister.
 * Following the battle, Aleister is attacked by Laura Stuart who is revealed to be the demon Coronzon possessing his second daughter's body. Immediately after her 'victory', she learns that the British Commonwealth is under attack and that Aleister has diffused into over a billion potential selves. At the same time, one of Aleister's potentials rescues Touma, who was blown out of the building during the attack.
 * The Processor Suit Arc begins.
 * Aleister launches the Windowless Building into space in order to delay Coronzon. The Reading Thoth 78 in the form of Mina Mathers prevents the demon's avatar from escaping before Aiwass intervenes. Aiwass grants Mina a grimoire to act as a vessel for her consciousness outside the building, allowing her to escape. Aiwass then faces Coronzon as the Windowless Building leaves the atmosphere.  Around the same time, Aiwass releases Lilith's essence back into the world through Academy City's AIM diffusion fields.
 * Coronzon uses Karasuma Fran as its secondary avatar, under the name A. O. Francisca, in an attempt to seize the Bank, attacking the trading office where its previous form was located and taking its new form, the Processor Suit. She places an identical suit on Hamazura Shiage as a decoy, but ends up targeting him due to an access conflict created by the two suits, making use of both the suit and Mimetic Predators.
 * While being pursued by both A. O. Francisca and Anti-Skill, Shiage comes across the baby Lilith and cares for her. With assistance from Takitsubo Rikou and the other members of, he manages to get Lilith to Heaven Canceller's Hospital.

 * Touma accompanies Aleister as they try to track down Coronzon's secondary avatar.

December 12

 * The Processor Suit Arc concludes.
 * As Shiage fights A. O. Francisca at the hospital, with Touma and Aleister joining the battle. Coronzon activates Index's John's Pen Mode but Mina uses her grimoire to disable the control over her. Having reunited with his daughter and received an oracle from Aiwass via Mina, Aleister annihilates the Mimetic Predators before surgically excising Coronzon from Fran.
 * After the battle, Aleister makes a deal with Touma, Accelerator and Shiage, aiming to travel to England to eradicate Coronzon's influence and save his daughter Lola.
 * Coronzon manages to defeat Aiwass and turns the Windowless Building around to crash onto Academy City, but Aiwass intentionally lost and made it so that Coronzon would end up shifted into the New World. After being toyed with by the Magic Gods, Coronzon manages to return to the regular world (dragging Nephthys and Niang-Niang along with her), only to find Academy City shut down by Aleister's virus and its population set to evacuate, with Aleister declaring war against the demon.
 * The Coronzon Arc begins.
 * Aleister temporarily seals Coronzon in Academy City using the Banner of the West, buying time for him to deal with the roots the demon has placed in the United Kingdom. Academy City is evacuated.

December 12+

 * The Coronzon Arc occurs
 * Following a trip through several countries, including Egypt where Lilith is left hidden in Mina's care, Aleister and Touma's group arrive at the Strait of Dover as the Crowley's Hazards overwhelm the crossing and land on the Dover shores.
 * After landing at Dover, Aleister and Touma's group fly towards London in a non-magical balloon, slipping past the magical anti-air defenses. After passing Canterbury and the outer walls of the England-Londinium Fortress, Aleister engineers Touma's capture by the Knights so he would be taken to the Tower of London and be in a position to destroy the core of the final barrier protecting London.
 * Having been separated from the others during the landing, Hamazura Shiage and Takitsubo Rikou make their way to London by car, with Nephthys and Niang-Niang joining them. On the way, they pick up Agata and other members of the Agnese Forces.
 * Following the barrier's destruction, Aleister arrives in London and fights Kanzaki Kaori and the Knight Leader. The defenders deploy the Divine Mixtures against Aleister and the Crowley's Hazards, transforming the London landscape into that of Egypt as imagined by the Europeans. Due to the defenders not knowing the proper way of using them, most of the Divine Mixtures are destroyed without displaying their true power.
 * The last Divine Mixture, Isis-Demeter, is brought to the British Museum by Oriana Thomson and presented to the Agnese Forces. Before any of them can offer their body to it, Orsolas Aquinas, overwhelmed by feelings of helplessness, offers up herself. Touma and Aleister face Orsola, possessed by Isis-Demeter and with her perception distorted, near the Palace of Westminster. Elsewhere, Accelerator interrogates Holegres Mirates, the knight responsible for the situation. The battle moves to the London Underground, where Aleister is seriously injured by Isis-Demeter's true power. Realizing the truth behind the Divine Mixture's power of weaponizing mutual intolerance, Touma eventually manages to get through to Orsola and get her to separate from Isis-Demeter, which they then destroy.
 * Arriving at Westminster Abbey, Aleister seeks Mathers' corpse in the graveyard in order to utilize its connection to Coronzon but finds another in its place. He is then confronted by Mathers himself and other members of the Golden Dawn, thought to be dead but apparently alive. Touma and Accelerator stand alongside Aleister.
 * Heaven Canceller, accompanied by a revived Kihara Noukan, goes to the RV where Mina and Lilith are hiding to help make a body for the latter.
 * After escaping from Westminster Abbey, Touma and Aleister's group flee into London while preparing their counterattack, pursued by the Golden Dawn. After encounters in Piccadilly Circus and the Isis-Urania Temple, it is revealed that the Golden Dawn are actually tarot-based grimoire reproductions, created by Coronzon as an anti-Crowley measure. During a clash with Mathers, Aleister is forced to unlock Academy City's technology to turn the tables. Shortly afterwards, Coronzon escapes the seal and takes flight.
 * As the Royal Family are being evacuated to Scotland, Mathers and the Golden Dawn move to pursue them, in order to prevent the barrier on the real Mathers' grave in Edinburgh Castle from being shattered by their presence. A battle ensues on the motorway between the defenders of the royal carriage and the cabal, with Touma joining in partway.
 * After being separated from the others, Aleister and Mathers face off in front of the church where Aleister was married, at sunrise. Aleister eventually succeeds in disrupting the flow of power from the ley lines to the grimoires, erasing the reproductions of the Golden Dawn.
 * The Coronzon Arc concludes
 * Reaching Edinburgh Castle and finding the real Mathers' corpse, Aleister attempts to use the connection to save his daughter from Coronzon. Too late, it is revealed that Coronzon had lied and she never was possessing Aleister's daughter. With Aleister heavily wounded and Mathers' corpse burnt, Kamijou Touma faces Coronzon, but his Imagine Breaker is ineffective against her and he is grievously injured by the demon's flaming sword. Aleister manages to save Touma, cutting off his right arm to prevent the Imagine Breaker interfering with the healing process. With Aleister and Touma both down, Mikoto and Misaki take advantage of Accelerator's arrival to escape from Coronzon.
 * Coronzon steals the Honours of Scotland and the Queen Britannia, intending to use them to hijack the United Kingdom's magical foundation and as the ignition of the Ceremony of Mo Athair, intended to cause the world's breakdown. At the same times, she commences multiple simultaneous attacks across the world through the ley lines in order to eliminate possible threats and incite chaos.
 * Starting at 11 AM, the British forces, aided by Touma and Aleister's group, attack the Queen Britannia on the frozen Irish sea, in order to thwart the Ceremony of Mo Athair. In the final stages of the battle, Coronzon accidentally breaks the seal on the entity lurking behind the Imagine Breaker, resulting in her defeat and the ship's destruction. Touma is subsequently forced to flee in order to prevent the entity from harming anyone.
 * Shortly after noon, as the bisected Queen Britannia sinks and following an encounter with Madame Horos, Aiwass and Anna Sprengel, the dying Aleister entrusts Accelerator with the full authority of Academy City's Board Chairman. Although her own body dies and is recovered by the British forces, an unexpected side-effect of the 1909 summoning results in Aleister taking control of Coronzon's body.
 * The Kamijou Arc occurs
 * In the aftermath of the battle with Coronzon, as a result of the damage he sustained and his own regrets, an emanation of Touma's power takes on his form and makes off with Imagine Breaker, intending to usurp his identity as a party is held at Windsor Castle to celebrate the victory over Coronzon. These circumstances and subsequent manipulations eventually result in a battle between the two Toumas and associated forces at the castle, ending with the original regaining everything that the other had taken.
 * As Academy City recovers, several days after the initial evacuation, students return to the city from around the world. Accelerator takes his seat as the new Board Chairman. Remaining in the UK, the recreated Dion Fortune offers her services as a new Archbishop for the Anglican Church. Meanwhile, Anna Sprengel plans her own moves to make up for the two outcomes which defied her expectations, and Aleister warns Tsuchimikado Motoharu of the new threat which has emerged in a coded message.
 * With her knowledge, manipulations and hidden Rosicrucian treasures stashes, Anna Sprengel founds R&C Occultics, an IT company specializing in magic, recruiting numerous sacrificial pawns to support the growth of the company, itself intended as a sacrificial piece for her true goals. With both Magic and Science Sides not able to properly tackle it, the company rapidly expands.
 * One of the companies that R&C Occultics seizes control of is Space Engage, with the Logistic Hornets being exploited for a worldwide delivery system and atmospheric control weapon rather than the easier space travel they were meant to achieve. Many of the original start-up employees are driven away, but Melzabeth Grocery stays to unsuccessfully try and prevent her dream and creations from being abused.

December 24

 * The Christmas Eve Arc occurs.
 * Misaka Mikoto and Shokuhou Misaki work together to escape Tokiwadai's strict Christmas oversight while mutually intending to betray one another, with Mikoto being the one to succeed. She runs into Kamijou Touma shortly after midnight as he is caught up in trouble caused by an incognito Anna Sprengel, and again while trying to escape from a mob of Tokiwadai students and teachers, after Touma's remote remedial lesson was cut off by technical failure with no way for him to contact Tsukuyomi Komoe. Unsure how to spend Christmas Eve, Touma, Index and Mikoto end up playing a darts game at a bar.
 * As Board Chairman Accelerator has turned himself in to Anti-Skill and is preparing to initiate Operation Handcuffs to eliminate the Dark Side of Academy City (with Yomikawa Aiho visiting him in the final stages), Board Director Neoka Norito has his agent Maidono Hoshimi attempt to kidnap Last Order for use as a bargaining chip. Though injured in the initial kidnapping, Touma manages to defeat Maidono and foil the abduction with help from Misaka 10032, Mikoto and Index.
 * With evidence of Neoka's involvement uncovered, the group head for his base as Anti-Skill also moves in, interrupting him in a staged attempt to frame Anti-Skill for alleged injuries and use their rules to impede their investigation long enough for him to eliminate the incriminating evidence. Neoka attempts to eliminate them using magic he acquired from R&C Occultics, which he helped to spread but didn't recognize as the occult, but is defeated by Touma with help from Othinus.
 * After the director's defeat, Touma is ambushed by Anna Sprengel, her identity now revealed, who forces a black pill into his mouth.

December 25

 * The Christmas Day Arc occurs.
 * Having been infected with the St. Germain virus, Touma is hospitalized, meeting Shokuhou Misaki and a hospitalized Aogami Pierce. He eventually learns from Heaven Canceller that his condition (the true nature of which not known to the doctor) is going to soon kill him at its current rate of progress, the virus spreading throughout his esper body and wrecking it with the rejection reaction as it automatically refines magic power inside it.
 * Hearing the severity of Touma's condition, Mikoto and Shokuhou confront Anna Sprengel in hopes of extracting a cure and stalling her march towards the hospital. Despite bringing their strongest tools and their best efforts, they are no match for Anna who toys with them until she loses interest and crushes them.
 * Incidents and casualties across the world due to the spread of magical knowledge by R&C Occultics continue to rise, particularly among Academy City's esper population, overwhelming the city's hospitals. On learning that the girls went to face Anna, a dying Touma attempts to leave the hospital, rejecting help from Maidono Hoshimi and Aihana Etsu, but coming to an understanding with the now-aware St. Germain inside him.
 * Touma confronts Anna outside the hospital as she was about to finish off the girls, working in tandem with the magic-wielding St. Germain, with Anna fighting with powers formed and focused on her right hand in mockery of her opponent. At the same time, Index and Othinus work to save the hospitalized espers from their affliction. On the ropes for most of the fight, Touma and St. Germain manage to use knowledge spread by R&C Occultics to deduce the nature of Anna's spell and disrupt it long enough to land a knock-out punch.
 * With Touma on the verge of death, St. Germain converges the virus comprising his being on Imagine Breaker and sacrifices himself to save Touma. Mikoto and Shokuhou are hospitalized, while Anna lets herself be captured and imprisoned in a cell next to Accelerator.
 * The Operation Handcuffs Arc begins.
 * Late in the afternoon, Anti-Skill is fully mobilized for Operation Handcuffs, along with several volunteers from Judgment. However, due to the influence of the Coins of Nicholas, which R&C Occultics had distributed amongst the city's populace early in the day, the operation spirals out of control and devolves into a bloodbath which leaves both Anti-Skill and the Dark Side of Academy City crippled.
 * In the latter part of these events, survivors discover Academy City's Greatest Taboo and head towards the Vanishing Tunnel in order to flee the city, but are slaughtered by Frillsand . After Kihara Hasuu manages to neutralize the artificial ghost, Drencher Kihara Repatri loses his life but Hamazura Shiage manages to defend the children in Drencher and Frillsand's care, and defeats Ladybird. Hasuu dies after a wish on a Coin of Nicholas to make Hamazura's gun malfunction causes it to go off and shoot him, but manages to persist as a ghost from reverse engineering the technology behind Frillsand.

December 26

 * The Operation Handcuffs Arc concludes.
 * The Los Angeles Arc occurs.
 * Identifying R&C Occultics HQ in Los Angeles, Academy City and the Anglican Church join forces to eliminate them in Operation Overlord Revenge. In response, R&C Occultics uses a combination of Citrinitas and the Logistic Hornets to engulf the city in sand and make the entire population disappear, attackers included.
 * Touma accompanies Index as she is brought with Stiyl and Kanzaki to LA to investigate the mass disappearance. Following clues left by a vanished Melzabeth Grocery, they find her daughter Helcalia, the sole person to escape being swallowed up. After Kanzaki falls victim to Citrinitas and Space Engage's creations are revealed to be involved, Touma and Stiyl come into conflict over Melzabeth's apparent role in these events. Touma follows Melzabeth's trail separately to prove her innocence, while the culprit attempts to frame her for their crimes.
 * In Academy City, Accelerator's trial for the clone murders commences, but runs into difficulties from attempts to impede it. During a break, a communication with Archbishop Dion Fortune convinces Accelerator to take a risk and allow the Sisters to reveal themselves to the world in order to help Touma and his efforts to exonerate Melzabeth in LA, resulting in a favorable worldwide reception for the clones. The Sisters fight the hijacked Five Overs from the operation, while Touma focuses on Citrinitas.
 * At the same time, during a charity debate at the White House, Vice President Darris Hewlane is revealed to be in league with R&C Occultics, his betrayal motivated by a desire to seize the presidency. His double clashes with President Roberto Katze in a gun fight, while also fighting Touma as Citrinitas in LA. He is ultimately bested in both battles and the core of his spell destroyed, freeing the trapped people from the sand.
 * While Melzabeth and Helcalia reunite and Accelerator's trial concludes, the executives of R&C Occultics are brutally killed ahead of the Anglicans' arrival by Aleister Crowley in a message to Anna Sprengel, who has made contact with the Bridge Builders Cabal elsewhere.

December 29

 * The Post-Handcuffs Arc occurs.

December 31

 * The New Year's Eve Arc occurs.
 * Kamijou Touma takes up Kumokawa Seria's situation and journeys to Shibuya for a part-time job to earn money to survive until the ATMs reopen on January 4th, ending up making food deliveries. Shortly before departure at 9AM, due to the circumstances in the Bridge Builders Cabal, Aradia makes an attempt on Touma's life which is thwarted by the Bologna Succubus and Good Old Mary, with Touma himself not fully aware of what transpired.
 * In the early afternoon, Aradia tries to assassinate Touma again, the other two again intervening. The Bologna Succubus escapes through the air with Touma, filling him in on the situation along the way. The two hide in the Miyashita Ark shopping mall as the witch searches for them. Eventually finding them, Aradia is narrowly repelled but escapes when Touma focuses on the injured succubus instead.
 * After the sunset, having converted thousands in Shibuya into a new coven, Aradia sends the group to kill Touma. In response, the Bologna Succubus uses her own magic to incite mass hysteria against them, with Shibuya falling into chaos as witches clash with 'witch hunters'. Pursuing the Transcendents in order to put a stop to it, Touma arrives as the succubus is mortally wounded, having lost too much blood in the process of reviving Touma previously for Good Old Mary to use her resurrection technique. But after Kumokawa's suggestion of using a blood substitute, she, Mary and Index take the demon to find one, while Touma stays to face Aradia with Othinus at his side. The girls manage to find a substitute in time, while Touma eventually defeats Aradia.
 * Having taken advantage of the chaos to retrieve the preserved body of Anna Kingsford from the Miyashita Ark, Aleister reanimates her using technology and she easily defeats Anna Sprengel before she can cause any mischief in the aftermath of Aradia's defeat, sealing her alive. Aleister then interrogates Anna Sprengel about the Bridge Builders Cabal and Alice Anotherbible. Meanwhile, as the year ends, Touma discovers via phone call that his parents actually could have transferred money directly to him after all and gets set upon by his angry roommates.

January 1

 * The New Year's Arc begins.

January 3

 * The New Year's Arc continues.

Trivia

 * It is unclear which years the series takes place in. There are some hints that it is in the first decades of the 21st century, as evidenced by 1700 years having passed since the rule of Constantine the Great in the 4th century and Aleister Crowley being said to have died more than 60 years ago in 1947. The global population is also said to be of 6 billions (and in later volumes, 6 or 7 billions), as was the case from 1999 to 2012, but the Catholic population is of 2 billion adherents and the British population of 90 millions (as opposed to 1.2 billion members and ≈ 60 million British in real life). Furthermore, the year has been stated to have the third Friday of March as March 15 and five Fridays in September, which should technically be impossible. Regardless, one should keep in mind that the Toaru Majutsu no Index universe is first and foremost a fictional universe, so it's expected to not always be comparable to ours.
