Ok, so the plot if this story is that a family((based off of my family but different still)) is sucked into killing game and the only way to escape is to kill one of your family members. They're trapped in a mansion some of the doors are closed, yada yada the usual. it's pretty much Danganronpa but with a family instead of a highschool class, and yes they do have ultimates. Also you can use this idea just credit me if you do.
