Very useful to have if you want to manipulate someone. She may become a Yandere because of the book, she falls in love with Senpai. But she will have rivals that she has to eliminate, and the first rival is Ameria Amamiya. Or she can become Deredere, she will want to eliminate the people she doesn't like, and her first rival is Ameria.
