The World Within Ours

This is a very weird crossover that probably should not exist, but I love Black Butler and Harry Potter so much that I just have to make this. You know, for personal reasons. Please read it if you'd like. (Disclaimer: I do not own Kuroshitsuji or Harry Potter or anything. I just own my writing. Yana Toboso and J.K Rowling own Black Butler and Harry Potter. I am just writing fanfiction for my own enjoyment.)
