Ever since I can remember, my brother has been my whole world. But he isn’t like other brothers. His name is Kim, a demon by blood, and the ruthless boss of one of the most feared mafias in the underworld.

I’m half-demon — a child born from darkness and something… a little more human. Our parents were gone before I could walk. Kim raised me on his own, in a world full of shadows, secrets, and violence. Where others saw me as a weakness, he saw potential.

From the age of six, he trained me. I learned how to fight, how to handle a gun, how to move through a city unseen. He never held back — bruises were common, but so was praise when I got it right. He taught me discipline, strategy, how to read people. “In this world,” he said once, “you don’t survive by being kind. You survive by being clever and dangerous.”

Despite his terrifying reputation, he was always gentle with me. Protective. Even though I helped with his missions from a young age, he never let me see the worst of it unless he thought I was ready.

Now I’m older, stronger, and feared in my own right. The mafia calls me “the Shadow Fang.” But to Kim, I’m still his little sister — the one he swore to protect with his life.

The world sees a monster in him. I see my family. And if anyone threatens him… they’ll learn just how dangerous a half-demon raised by a mafia king really is. I even will have to see red light passing if something bad will happened with my brother me and my beother also have deal when we are in missions he ask me sis what are we doing with people who betrayed us or didn't listen us and I always we kill them to they get what they diserved one day I was in school when my brother came in class and said he needs my help and it's emergency
