Crazy Crossover! Can they survive?!

Originals, Yugioh, Buffy the vampire slayer, Percy Jackson, Harry Potter, Twilight, and Supernatural crossover. This was a request from my sister. All of the characters go to vacation to the same spot. Some mysterious man knows all of their secrets and wants to kill them all. They have to all work together to survive. Will they? or will their stories end in blood and gore.

Don't own Originals, Yugioh, Buffy the vampire slayer, Percy Jackson, Harry Potter, Twilight, or Supernatural.
