The Son of Perdition (Descendant of Cain x DxD)

"After Cain killed Abel, Evil made flesh..."

That's what the Old Man told me. Once, I was nobody. Just a street urchin running through the snowy streets. Until one day, I met him. He had the same aura as the people who tried to kill me, but he didn't have the same intent. His name is Ivis, Elder of the Necron Clan.

He took me in after noticing my birthmark and made me the Vanguard for his descendants.

Two years ago, he sent me back here. Mostly because those two are attending school now, and he thought I needed a "vacation" from my duties as a Vanguard. But I know he has another plan in mind, because what I expected to be a normal school life will change everything I know... forever.
