A couple of spooky ideas

Idea One: "What a sweet family!"

"Ahh yes, there go the Ichimasu's, such a nice upstanding family! The whole family are always such a delight to have around, you can really feel the love. Why they're always working on some project or another, they must stop by the hardware store 3-5 times a week, always picking up new axe handles, saw blades, and plenty of tarps. I hear they've got a wood shop in the basement, of course that's just a rumor, they don't let anyone down there. I kinda feel nervous for them though, what with all of the disappearances in town you gotta be! Why if anything happened to them I'd just be heartbroken. But they don't seem bothered, why just the other day I saw husband and wife taking a moonlit stroll through the woods, just the 2 of them hand in hand, carrying an axe to chop some firewood for a romantic evening under the stars and a shovel to throw some dirt on the fire afterwards. Not sure what was in the bag they were carrying though, seemed awful big, but some folks like to be prepared for anything I guess!" 

So for this idea YC would either be the wife or daughter (or both if you're willing to play a double role) in a family of serial killers. I'd be playing the husband or son (or both if we decide we both want to double up). We can approach this from a few ways, either have them hunting different victims or perhaps using them for some sort of dark rituals, and of course there would be a heavy sexual element to it all as well, including possible incest if that's what we agree on, but it doesn't have to be involved.

Idea Two: Okay for this one I'll admit, it's not as thought out, but I've been craving a chance to play a "Chucky" like character. Basically a murder gets his soul placed into a doll and continues his crime spree, using his new body to hide in plain sight and get away with literal murder. Somehow he ends up in the possession of a single mother and her teenage daughter, where he decides to continue his spree. YC could play either the mother or daughter, I figure we could experiment with some different psychological torture concepts as he makes YC think she's insane, along with physical torture which in this case would be closer to hardcore BDSM then actual torture. Everything is up for discussion.
