Ruby
What's there to say, really? I was born. I grew up. Killed some people in between those two points, then some after. It was absolutely delightful.
Daddy had plans for me. Big plans. I wasn't into the idea, so I screwed the old bastard over and now, lucky you, you're talking to the King of Hell.
Better mind your manners. It'd be a shame if I had to kill you. I'm still giddy about exploring this whole demon wife aspect of my new life.
