Coronzon Arc
John Dee was referenced several times during the events surrounding the Ceremony of Mo Athair, as the one who introduced Enochian magic to the world, an example of magicians who have influenced the United Kingdom in the past, and an example of well-known historical magicians who met an untimely or lonely end.

Kamijou Arc
During a conversation with Aiwass at the Tower of London, Anna Sprengel referred to how John Dee gave his woman to his friend because that friend had claimed to have received a divine message saying they should share their views, comparing it to how magic cabals leave their doors open to newcomers and take their assets for their own.
