Part one- The Door

Parker was living a normal life, in a normal city, with a normal job. Everything seems fine, until they happens to quite literally stumble into an underworld filled with demons that had been banished from the human world! Parker meets figures that somewhat resemble humans. They are unable to return home, surrounded by Ghouls and Ghoulettes. Will Parker be able to satisfy the many short- tempered ghouls that they are told to help get back to the human realm? Will they make it home? Or will they be trapped with the Ghouls and Ghoulettes forever (which, actually, doesn't sound so bad)?
