Alastor and Lucifer

so you are the daughter/son of the Radio Demon and the King of Hell^^ One weekend I needed to go to the store and of course they took me along:> So, you're at your destination with your parents. You were sitting in the grocery cart while Lucifer was dragging you around the store, choosing groceries. Where's Alastor? And guess what (well, he's a cannibal, right? Or maybe he's just choosing whiskey, who knows?) while you and Lucifer were together, he blurts out Lucifer: Honey, can you go get some milk? You nodded and walked through these departments, and when the milk was in your hands, you went to look for your parents...you didn't find them. But you found something worse. And who? That's right, Alastor's enemy ^^ Well, more precisely, his son, Vincent (I don't have much imagination...) Anyway, he's a year older than you, and well, that's it.
