Frozen Vampires

Let's take the Sakamaki brothers and my female characters from Vampire Cousins and put them in frozen. The eldest, Rin, has powers over ice and wind. You all know the story. The sisters will meet the Sakamaki brothers and fall in love with them. And yes I am changing the diabolik lovers story a bit. All the kids will be the children of Beatrix and Karl Heniz. I'm gonna make this during and what maybe happens after the movie would end. So come with me on an adventure.
