[[http://faith.rydia.net/ Demonology101]] is an UrbanFantasy webcomic by Faith Erin Hicks which ran from 1999 to 2004, and for some time held the distinction of being the longest completed [[{{Webcomic}} online comic]].

It focuses on the daily life and adventures of a demon named Raven, a foundling left for [[MosesInTheBulrushes mysterious reasons]] with the Network, a secret society dedicated to ''fighting'' demons. Although her adoptive father, Gabriel, has left the organization in hopes of giving her a normal life, Raven's heritage will not permit a quiet existence, and Gabriel's own past is starting to catch up with him...

!!This series provides examples of:
* AwfulTruth: Several.
* BadassNormal: Almost all of the protagonists are completely normal humans, and the few that aren't aren't any more effective.
* DealWithTheDevil: The Jenner family, who are charged with acting as Hell's representatives on Earth. Deal first made by a distant (as in [[BibleTimes first century]]) ancestor.
* DemonicPossession: Once. [[spoiler:Ironically it's Raven who is posessed]]. Not implied to be possible for normal demons.
* EvilParentsWantGoodKids: [[spoiler: In the backstory A Distant Faith, Alexander Jenner asks Mr. Sachs to free his son from servitude to the Devil. http://faith.rydia.net/adistantfaith/page32.html]]
* GoodThingYouCanHeal: Mr. Sachs gets stabbed an awful lot. No matter he's always trying to quit.
* HalfHumanHybrid: Subverted. [[spoiler:Raven eventually finds out that she is half-demon and half-angel.]]
* HeelFaceTurn: Mr. Sachs.
* HeyYouHaymaker: [[http://faith.rydia.net/episode1/page43.html John does this to Mr. Sachs]].
* IsThatWhatHeToldYou
* LukeIAmYourFather: [[spoiler:The angel Aaron is Raven's father.]]
* FromACertainPointOfView: Poe calls Gabriel out on this in regards to Raven's origins [[spoiler:though later on he just lies about it outright]].
* OurAngelsAreDifferent
* OurDemonsAreDifferent
* ThePlan: [[spoiler:The entirety of episode 2. It goes almost flawlessly.]]
* RedEyesTakeWarning: Somewhat subverted. Raven has red eyes [[WordOfGod according to the author]], though she isn't evil. Since the art is black and white it is unknown if other demons do.
* RousseauWasRight: There are some truly horrible characters, but despite talk of rules and lacking free will demons and damned humans can still choose to be good (and several turn at the end).
* {{Tykebomb}}: Lacey.
