Rizevim was sitting in a chair when a servant appeared before him. "My lord, the child was left in the human world just as you ask". Rizevim smiled "good, I want to see how he grows, no one interfere with his life". The servant nodded and left.
(Mc pov) Five years have passed since I was reborn into the DxD universe. I was looking in the mirror at my white silver hair and blue silver eyes, the traits of the Lucifer bloodline.
A system screen was in front of me. [Status:pure blood devil(artificial) bloodlines-Lucifer, leviathan, Beelzebub, asmodeous] I stared at it. Hard. "Ok so this is how my day is starting, system what bloodline abilities do I possess?" [You possess (Lucifer demonic power supremacy) (Beelzebubs king of flies) (asmodeous's starsend moment)]
I blinked as I asked "ok why those ones only?" [It's because you're dealing with multiple king lineages. Normally they would have fought for supremacy, and they did, which is why you only have three out of there many bloodline abilities]
I couldn't even fault it, just today I still thought I was a normal kid, then the system awakened and my memories of my past life appeared as well. I summoned up some demonic power. It was instinctive and messy.
