Vindicta

In a certain fantasy world where humans and the like coexist, a big injustice occurs everyday.
Demons wage war at the other races for supremacy and those who are captured become slaves.

But one demon is different, one demons seeks for venegance, and to change the world.
How will that go?

(Inspiration has been taken from Destiny, so no point of coming to shout at me for that :P)
