A small black book with the words "Fuck Note" scrawled on the cover was found by Misa Amane. As she opens it, she sees multiple names scribbled next to one other.

You are no novice and have seen books of this type before; fortunately, you possess a pen and an inventive notion of your own Light to place your name beside hers. What comes next?
