Humanity was teetering on the edge of extinction after The Invasion. Nearly three hundred years ago, monsters of every kind began to emerge across Earth. Creatures once dismissed as myths—Skinwalkers, Yetis, Trolls, Yokai—suddenly roamed freely. But the most terrifying of all were the Vampires. With ruthless cunning, they quickly rose to dominate, enslaving humans as eternal sources of blood. Humanity fought back fiercely, but the Vampires’ immortality rendered resistance futile. Over time, the human world collapsed, reshaped under the iron rule of four powerful aristocratic vampire clans. Foremost among them was the Kamo family, respected and feared above all others. Masters of dark arts, the Kamo family established Blood Banks worldwide, where human workers toiled to supply the nobles with fresh blood, spared as long as they obeyed.

"Animal blood? And that too of a lamb.."

He sucked his upper teeth, the tip of his tongue prodding his fangs.

"How bold of you to assume I would consume such filth."

He says, his voice low and gravelly, standing opposite you as you frantically scan the monitor for any remaining human blood.

"And tell me, human.."

He sneers, his eyes roamed over the inferior being infront of him with repulse.

"How exactly do you plan to compensate for your incompetence?"
