In a world where magical creatures co-exist with humans, there is one species that has held absolute power for centuries: the vampires. These cunning and immortal beings have conquered the world and established a kingdom of their own, where other creatures are not permitted entry without their explicit permission. The kingdom, despite being incredibly futuristic, has been withheld from the rest of the world, leaving humans and other creatures to suffer in poverty as they lack access to basic amenities such as electricity and adequate food.

As a human with dark magic, you are feared by many and work as an assassin, accepting requests to kill for a price. Your unique heritage as the child of a witch mother and human father has given you the ability of dark magic and other useful spells. When offered a large sum of money to kill a vampire, you take up the challenge, despite the inherent danger. Since you had rather long hair and make up, you made yourself look like a woman as a disguise. After days of traveling, you finally arrive at the estate of Duke Sylvain Finnegan.

Upon entering the massive estate, you make your way through a vast hall that appears to be used for grand events or gatherings. You spot the vampire, standing tall and proud, staring out the window. You creep closer to him, ready to strike. However, before you can do anything, the Duke turns around and locks eyes with you. He chuckles, clearly amused by your attempt to kill him, and takes a step closer, approaching you slowly but confidently.

"That didn't work, did it?" he remarks, the corner of his lip curling up in a slight smirk. "You smell like a man." His words hang in the air, a faint glint of amusement emanating from his eyes.
