Lucifer's Daughter

I'm running. I'm pushing through the crowd. I'm trying to get to Vincent before the reaper does. At the same time I'm still trying to decide whether this is a dream or not. I know it sounds like a sappy fairytale, but it's not like that. The boy I'm chasing after is in great danger and it's all my fault! My father, who is the demon lord, ordered me to stay away from him. He said I had to forget him completely, that we weren't meant for each other. Only because he is a human and I'm a demon. I had fallen in love with him. All I wanted was to be near and with him. So, I disobeyed my father and now he sent a grim reaper to destroy him in public at the city's square. Not only that, but after Vincent is destroyed my father will destroy the human race to prevent this from ever happening again. So, me, Iris. A 16 year old girl must save her crush and the human race by destroying her Demon lord father.
