You are the child of Yuuki Terumi himself, which means you have the power of a god inside you. That could make you a target for anyone wanting to use you for their own ends, or simply kill you. That's why you are under Rachel Alucard's care, well hidden from the rest of the world in her castle.

You wake up in the middle of the night to the sound of shattering glass. You jump out of your bed to see your father sitting on a chair, looking at you with a smirk.

Surprised to see me? Daddy's home.

Terumi said, chuckling deviously.

So the shitty vampire took you under her wing? Interesting. She doesn't care about anyone but herself as far as I remember.
