Evacuation of Academy City

The Evacuation of Academy City was an event which occurred on December 12th in the current year of the story timeline.

Following Coronzon's attack on Aleister Crowley in the Windowless Building on December 11th, the latter took measures to prevent Academy City from falling into the demon's hands. Shutting down the city and locking its technology with a virus via the Bank, Aleister had the population evacuate to various locations around the world while personally seeking Coronzon's achilles heel in the United Kingdom, aiming to grasp it while the demon was temporarily sealed in Academy City.

December Heatwave and 48 Hours to Restore Order
Barely a week before the evacuation, Academy City had been hit by an abnormal heatwave, the result of microwaves emitted from a certain space station, crippling its infrastructure, and was also infested with the Elements, creations of Kihara Yuiitsu. Following the end of the heatwave on the morning of December 9th, Useful Spider carried out repairs to the city in a period referred to as 48 Hours to Restore Order, completed on the morning of December 11th.

Having suffered due to the heatwave and infrastructure breakdown, and having only just recovered, the fear and dangers of a complete infrastructure collapse were fresh in the minds of Academy City's residents.

Aleister Crowley and Coronzon
When Aleister Crowley was knocked out by Kamijou Touma following their battle and his attempt to destroy the phases, he was ambushed and stabbed by Coronzon, who had snuck into the Windowless Building and took advantage of the opportunity, using the Sword of Damocles. Revealing herself to Aleister, Coronzon mocked Aleister with claims of having possessed his daughter Lola before infesting Aleister's mortally wounded body. However, her plans to toy with Academy City using the Board Chairman's corpse were cut short when it was revealed that Aleister had previously bound over a billion alternative possibilities of himself to his body, which had now diffused and manifested across the world, and were now attacking the British Commonwealth.

Having shifted his main consciousness to one of his alternative selves outside the Windowless Building, Aleister launched the Windowless Building into space to temporarily remove Coronzon and buy some time to act. The reproduced Mina Mathers and then Aiwass prevented the demon from escaping before the ship cleared the atmosphere, with the latter fighting her as the Windowless Building headed out towards deep space. Lacking an avatar, Aiwass was eventually defeated but ensured that Coronzon would be shifted into the 'new world' by relativistic effects on the return journey. After crashing the Windowless Building into the 'new world' Academy City, Coronzon was set upon by the Magic Gods, who saw a new toy.

At the same time, Coronzon's secondary avatar, a possessed Karasuma Fran under the name A. O. Francisca, attempted to seize the latest iteration of Academy City's Bank, the Processor Suit. A mistake in attempting to use Hamazura Shiage as a decoy with a second suit left A. O. Francisca unable to access the Bank, forcing her to go after Hamazura, who had also found and was trying to protect Lilith Crowley, returned to the world through Aiwass's actions. Coronzon's influence was eventually excised from Fran by Aleister during a battle in front of Heaven Canceller's Hospital on the morning of December 12th. While searching for A.O. Francisca, Aleister had also prepared a potent computer virus as insurance and the Processor Suit, though damaged, was left in a suitable state for it to be used.

Coronzon's Sealing
Early in the morning on December 12th, Coronzon managed to escape from the 'new world', dragging Nephthys and Niang-Niang along with her. She found herself in front of Heaven Canceller's Hospital and facing Aleister, whose consciousness had shifted to one of his diffused possibilities, a young girl. After revealing how she had sealed Academy City's technology, depriving the demon of its prize, Aleister sealed Coronzon temporarily using a city-scale Banner of the West.

Evacuation
While there was no official announcement and no clue as to the cause of the blackout other than a sudden flash like lightning, the population of Academy City, having only just recovered from the previous infrastructure collapse during the heat wave, quickly recognized the situation they were in and wasted little time in beginning an evacuation of the city.

As the city was being evacuated, Aleister Crowley set off to grasp Coronzon's achilles heel, accompanied by Kamijou Touma, Accelerator, Hamazura Shiage, Index Librorum Prohibitorum, Othinus, Karasuma Fran, Takitsubo Rikou, Tsuchimikado Motoharu and Mina Mathers, with Lilith and Sphynx in tow. From, they travelled along Southeast Asia and then headed to Egypt. There, Tsuchimikado took his leave, while Aleister left Lilith hidden under the protection of Mina Mathers in an RV in the desert, with Sphynx staying with them. The others subsequently crossed the to, travelled to France and then from , crossed the Strait of Dover to England. Heaven Canceller would later travel to Egypt to help give Lilith a physical body, after healing Kihara Noukan, who accompanied him there.

Some students were picked up by their families, while others made their own way. Some of the groups within the city remained together, while others went their own ways.

External Effects
Due to the world already being in chaos from the ongoing attack on the 53 countries of the British Commonwealth by the Crowley's Hazards, the effects of Academy City's shutdown and evacuation were less than some residents expected.

One side effect of Academy City's sudden shutdown was that the price of artificial mink skyrocketed.

Coronzon's Escape
While in London, Aleister encountered reproductions of the Golden Dawn, created by Coronzon as an anti-Crowley measure. Facing death at the hands of the reproduced Mathers, Aleister was forced to unlock Academy City's technology and fire a satellite laser to escape from Mathers' grasp. Shortly afterwards, Coronzon escaped from the seal and after fashioning herself a pair of wings from the 'contents' of spare parts from the Anti-Art Attachment, set off for the United Kingdom.
