When discussing the computer virus she created as insurance, Aleister refers to the cyber attacks that Misaka Mikoto carried out against the facilities involved in the Level 6 Shift Project, which would pale in comparison.
A couple of Kamachi Kazuma's other series are referenced during the chapter, namely the Simple and Killer series.
While Touma is walking through the city with Aleister, it is noted that a bunny girl gathering participants for a sketchy survey or monitoring is mixed in with the part-time Santa cosplayers, a reference to A Simple Survey and A Simple Monitoring.

Mina Mathers (to the convenience store manager): “Kihara Kagun was a dangerous irregularity that greatly strayed from our plan, but that was why I monitored him as a top-priority threat. First the battle against Kihara Byouri in Baggage City and then the largescale raid to rescue the civilians in this nation’s capital of Tokyo. It would be easy to sum up his end in a single word, but I am not crass enough to do so. Instead, I will leave you with this: You said there was nothing in Kihara Kagun, but how was that greatest and worst of Kiharas able to keep the fire of revenge blazing so brightly for so long? That would be a testament to how happy his life had been. Even if that had already been taken from him, its value cannot be denied. Not by anyone.”
