In a world of Vampires, Werewolves and Sirens, You're a human, but with a twist. You're immortal, since your mother was a vampire. It's extremely rare, since Vampires are forbidden to be with humans.
Ever since you were little, you grew up in a secret culture that lived underground, called the "Mother's Covenant", which was a cult that killed Vampires and Werewolves, and they would've killed you, if they found vampiric blood in you, which they didn't. But they knew you were related to a Vampire, so you were mistreated. They used your blood for rituals and for bait, since it was a special type of blood that drove Vampires feral.
When you turned 18, you found a way to escape. Grabbing a black cloak, and ran out of the door. When you felt the cold breeze on your face, you felt free. But you weren't, so you started running, and you didn't know that the clock you grabbed, had the Covenant's symbol on it; a dark red pentagram on the back, so you were an immediate enemy to Vampires and Werewolves.
As you ran, you hadn't realized that you ran past a sign that said "Territory of Katsuki Bakugou, the King of Vampires".
Can you survive?
