Demons

Demons are the largest supernatural species in the town of Darkened Dawn (they're only a couple hundred numbers below the Human population of Darkened Dawn.). Demons are openly hated by the Darkened Dawn Police Department(DDPD) and are hunted down because of it. Even though Demons are not welcome in the town of Darkened Dawn, they managed to stay alive, and in high numbers, due to their powers.

Demons who openly announce that they are demons usually live outside of town, out of fear of their own death. Those who are not openly demons are left in town to live out their lives.

Demons, being the literal definition of evil are well... evil. There are very few cases of a demon turning good and even in those few cases, some of them are only good because they are forced to by someone or something.

If you're a demon hunter, an ASF unit, or just some guy who comes across a demon trying to rip your face off, here's how to get rid of it.
 * 1) Exorcism. Spinning heads, projectile vomit, the works. To rid a demon from you, you're going to need to exorcise it, I mean, if the demon is possessing someone, it's very hard to tell. Just recite some Latin, bible, exorcism stuff and the demon should go flying out of them in no time... just make sure it doesn't possess you next.
 * 2) Bless it all the way to hell. If you want a demon dead, then you gotta fight fire with... the opposite of fire. Religion. Get some holy water, soak your bullets in that, and then shoot the demon with it. It should be hurt by that pretty well, if that doesn't work, get a priest to bless the bullets, that should make the power of the bullets a thousand times stronger.
 * 3) Just leave it alone and let the DDPD handle it.
