This world is divided in normals and monsters. Monsters, carnivorous demons in mundane form that only eat meat and... humans, also known as normals. To monsters, human flesh, or normal flesh, is far better than any animal meat. It tastes like heaven to them. Sometimes, no monster can resist to feed once tasted normal blood. This caused normals to fear monsters. For their protection, they depend on skilled normals to kill monsters-- Hunters. And so, Monsters hide away from hunters to feel safe. Safety? There's no such thing in a monster's endangered life. But can one find love and romance?
