[@Grifter] hope you dont mind me dragging you into this thread, but if you read the original post youll see the basis for my idea.

The ghosts of 5 undead girls terrorising the natural world. 

Now throughout this thread ive only been able to come up with 3, so if you have ideas I'd love to hear them

Also have you ever played the game Killer7? I think thats sort of how I want to have the protagonists, multiple characters who share one body.
