He Who Does Not Exist (Paperback) (ISBN-13: 9798998841613)

God allows the devil to temporarily make a few demons mortal.

The devil does this to improve those demons at getting souls and to select a lead soul catcher, an elite position in Hell. The demons, while on earth are mortal, meeting on a college campus, and explaining the deadly sins. Each demon is the embodiment of a deadly sin and most want to be lead soul catcher.

An angel points out the risk of making demons mortal, even for a short time; while a demon never gets the choice, a mortal can choose salvation.

Now, one of the devil's demons, Penny, who represents the sin of Pride, may be at risk of being saved.
