Comics are a wonderful medium for conveying episodic content in an incredibly small space. As such, they are often used to convey morality, science, storytelling and, of course, humor.
Hell Inc is a daily webcomic focusing on the balance of good vs. evil and how mutable it can be. The comic focuses on Kevin, a minor demon sent to Earth on a mission, and an angel named Levi who is determined to foul up his plans. With no friends, a hostile environment, no powers and completely the wrong idea of what to do, Kevin looks to be in a hopeless situation.
