Demons

Demons are the humanoid creatures of Hell. They are mean, vicious, and bloodthirsty. Power is everything to Demons, so killing other Demons to achieve power is fair play, though many aren't courageous enough to do so. Demons use dark magic, have a Human and Demon Form, and have Demon wings. Due to their greed, they invaded the Human World and continue to fight with the Angels and Humans.

Demons are very weak to light magic. If any instance of light magic enters the body of a Demon, they disintegrate instantly. Because of this they can't enter the Angel World, which is full of divinity, a form of light magic.
