A New Born Devil?

Hello, I am Ray Gremory, and I think... I killed Rias Gremory...I am the second son of Duke Zeoticus and Duchess Venelana Gremory. I apparently was born when Rias should have been. I am the only other child my parents have, so that is why I said I killed Rias Gremory. Oh, and my older brother is the Devil King, Sirzechs Lucifer, that I am constantly compared to because I was also born a Super Devil, sigh. How do I know I took Rias's spot? Because when I was 4 years old, I was kicked in the head by one of our family camels and regained a few of my past life's memories. Damn, I forgot most of the story-line of my new world, so nothing is going right in my new life. "Please God help me..." *PAIN*... "Ouch, Damn you God!"
