Referbacks

 * The earlier attempt by Karasuma Fran and Tsuchimikado Motoharu to escape over the city wall is referenced with regards to some of Fran's actions under Coronzon's control. This includes her choice of Shiage as the decoy, whom the group had passed on the bus as he was helping to install ATMs, and the retrieval team outside the city, whom Aleister guesses were likely Kanzaki Kaori and the Amakusas, through which Coronzon snuck its primary avatar Lola into the city and then the Windowless Building.

Cultural References

 * When explaining the Mimetic Predator, Aleister refers to his Loch Ness experiment and the, the story of which apparently arose due to sightings of a few half-formed spirits that welled up on their own as a side-effect of the experiment.
 * The real-life Aleister Crowley owned near  between 1899 and 1913, where he carried out a series of rituals from . The Loch Ness experiment is likely a reference to this.


 * Aleister refers to the demon's method of strengthening its avatar as being like an instant version of a master.
 * In describing Aleister's use of Spiritual Tripping, the narrative compares it to the Japanese urban legend 'Purple Mirror' (紫の鏡), involving a cursed phrase which will kill a person if they remember it until they reach 20. Just like how someone may try to forget the phrase and end up only focusing on it more, the target may try picturing another image to avoid picturing the implanted one but end up narrowing it down and being unable to escape.
 * Aiwass refers to just before Coronzon unknowingly enters the New World.
