Aleister Crowley/Chronology (Souyaku Toaru Majutsu no Index)

This article covers Aleister Crowley's chronological history in Souyaku Toaru Majutsu no Index.

Operation Handcuffs Arc
After the events surrounding Operation Handcuffs, Noukan met Aleister in Shinjuku, which was located near Academy City's East Gate. Noukan asked him either is going to intervene or watching Academy City collapse. Aleister will leave for Accelerator's decision. They also talked about their true goals about destroying all magics. Noukan urged him to get back work.

Los Angeles Arc
On December 26th, immediately after the defeat of Citrinitas and the release of Los Angeles's trapped population, Aleister and Noukan visited R&C Occultics HQ ahead of the joint Anglican-Academy City force, with Aleister gruesomely killing the executives and sending a message to the absent Anna Sprengel, the two leaving before the joint force arrived.

Post-Handcuffs Arc
On December 29th, Aleister and Noukan briefly visited Academy City as part of preparations for the upcoming confrontation with Anna Sprengel. Late in the day, Aleister ran into Kamijou Touma, who was tangled up in events surrounding the crash of the Overhunting and the escape of its prisoners, survivors of Operation Handcuffs. Repeating these events after rejecting the intervention of Alice Anotherbible, the injured Touma expressed relief at Aleister's survival but firmly rejected his offer of dealing with the dark side members.

While Touma and Hamazura Shiage were dealing with Kihara Hasuu's ghost in Vanishing Tunnel, Aleister visited the former site of the Windowless Building, joined by Noukan after the dog had done his part in the battle. Though the building was gone, its foundation and original network still remained, so Aleister was able to reacquire access by repairing the damaged and concealed portions and carry out a search. Bitten by Noukan for a comment regarding romance and male genitalia, Aleister found the location where Anna Kingsford's corpse had been preserved.

New Year's Eve Arc
On December 31st, during the events in Shibuya, Aleister and Noukan took advantage of the absense of people caused by the effects of the battle between Aradia, seeking to kill Kamijou Touma, and the Bologna Succubus, trying to save him. Accessing the hidden treasure store in a restaurant kitchen in the Miyashita Ark, Aleister retrieved Anna Kingsford's body and prepared it for reanimation.

After the battle between Kamijou Touma and Aradia, the reanimated Anna Kingsford confronted and easily defeated Anna Sprengel, sealing her away into parchment charms in a film can. Immediately after she released the separation that isolated her and Anna Sprengel from their surroundings during their clash, Aleister reached for the safety switch he had installed in her back and retrieved the sealed Sprengel. After a brief talk with Aleister on what a magician was in her mind, he switched Anna Kingsford off, but not before she warned Aleister that while she would do someone's bidding if it would lead to a positive result and help others, if their behavior went beyond what she deemed necessary, she wouldn't hesitate to turn against them. Aleister then picked up the sealed Anna Sprengel and started interrogating her about the Bridge Builders Cabal and Alice Anotherbible, which he recognized as a product of Magick, also saying that he would not let her or anyone else toy with Touma's life any further.

New Year's Arc
On January 1st, Aleister and his companions were on the roof of one of Shinjuku's tall buildings with a view over Academy City's outer walls, interrogating Anna Sprengel over her plot with R&C Occultics and the Bridge Builders Cabal. Aleister drew a chalk magic circle to backtrace the cabal's headquarters from the connection Sprengel had formed with them through her meddling and had Anna Kingsford perform the magic, surprised when it pointed into Academy City.

On January 2nd, as they were heading into the city once more, towards the cabal's newly-established consulate in District 12, Aleister considered the Transcendents and their possible connections to his Magick system.

On the morning of January 3rd, Aleister and the others were approaching the consulate, as well as the truth behind the Transcendents and the Bridge Builders Cabal's plans, when they encountered Aradia and then the injured Kamijou Touma, fresh off from the conflict that had erupted over the matter of the cabal's intent to execute Anna Sprengel straight away for her actions and his intent to change this decision. On seeing Anna's sealed form in the film canister, a roaring Touma broke the seal with Imagine Breaker and ran off with her, to Aleister's shock and dismay. As Aleister was crying over how things had turned out in the aftermath, he was comforted by Anna Kingsford.

Following the escape and the declaration of martial law in Academy City, the trio continued their movements against Anna Sprengel and the Bridge Builders Cabal across the next couple of days, with anti-recognition magic concealing them from Anti-Skill. While planning their actions, they used a room in District 23's Science Tower as a temporary base. They eventually ended up facing Christian Rosenkreuz on the night of December 4th, in the aftermath of the Transcendents' ceremony.
