The pressure felt like an asteroid at this point. Aleister Crowley used her heel to shove the Great Demon into the dark wet asphalt.

Then, with an odd sound reminiscent of a punishing lightning strike from heaven, an unnatural light flashed through several of the roads that acted as Academy City’s arteries.

That light drew a giant equilateral triangle with a cross carved into the center.

Anyone who knew anything about modern Western magic would immediately recognize it as the Banner of the West. That symbol of exorcism was one of the most convenient Symbolic Weapons that protected the spell user by monitoring and rejecting the approach of evil power on the ceremonial grounds – for example, something resembling Telesma that was out to get humans. The banner was so useful because good and useful powers would remain unmolested while only the evil and useless powers were affected.

It only took an instant.

Once the light vanished, nothing remained.

Not even the golden demon sinking into the asphalt.
