Berserk. Out of control with anger. This is what Natsu was born to be. A warrior soaked in blood. A murderer. This is what Pergrande turned him into. Taken at a young age by the King, Natsu is a soldier of the Royal Army, a creature of rage and violence—a weapon. Lucy is a thief from Fiore with a price on her head and magic in her blood.

Natsu and Lucy are from warring clans, each acting as a powerful warrior for their people. Natsu's clan consists of skilled blacksmiths, crafting weapons from the earth and enchanting them with lost elemental magic. Lucy's people are Spiritwalkers, powerful seers who can make contracts with ancient spirits from the bones they leave behind. (enemies to lovers AU)

Of all of the stupid shit Lucy has done while drunk, entering a contract with a demon probably takes the cake. The icing on said cake, however, is the fact that neither of the two know what the terms of the contract are. Until they figure it out, Lucy is stuck living with a demon who doesn't really understand the concept of keeping a low profile.

Lucy: a ruthless Vampire Slayer. Natsu: a not-so-ruthless S class Vampire. Out on a Solo mission, Lucy is kidnapped by her enemy, Natsu, who in-visions harmony. Will this bad-assed Vampire Slaying princess, fulfil her duties as a slayer, or will the vampire pursued her for world peace? Or will the anger of her past surface, turn to bitter hatred?
