The Devil's Panties is not, in fact, satanic porn. It's an autobiographical comic strip about a girl in flame boots who works at a comic shop while dreaming of being a successful comic artist.
As Jennie starts getting traction on her dream, Nigel the Pirate enters her world and shows her the ropes, slopes and gropes of convention life. However as things start to go awry, her conscience summons supernatural "help" from on high and down low.
Little did Jen know that they would overstay their welcome.
