After Early Humans win a war against a powerful supernatural species, some individuals are left with strange abilities. These individuals, known as Vampires, go on to blend into society in an attempt to live normal lives. Over time these Vampires spread throughout the world, and like all humans some of them turn out more sinister than others. Naturally this results in secret organizations being formed around the world to hunt down these potential threats. As this battle of "good and evil" persists behind the scenes, society progresses with most humans only hearing about vampires in folklore or works of fiction. However as humanity enters the digital age, the existence of vampires is inevitably revealed to the world. This causes Vampire activity to grow exponentially, bringing Vampire Hunters into the spotlight as humanity looks for protection. Thicker Than Blood is a story that follows a young vampire woman and her human brother as they enter the world of Vampire hunting.
