Paxton Holley's Reviews > Lucky Devil

A regular average guy named Stanley is possessed by a demon, then a second rate exorcist performs a ritual that expels the demon but leaves all of his supernatural power inside Stanley. Stanley isn’t sure what he wants to do with this demonic power, and he’s unsure if that power is also corrupting him the more he uses it

This was pretty good with great artwork. Can Stanley control the power? Is the demon trying to get his power back from Stanley? And is Satan himself not happy that a mortal now has the power of a demon lord?
