When Saiki heard about ANOTHER transfer student, he didn't expect this. Saiki Kadoka. She is smart, athletic, fit, cute, basically everyone likes her. She doesn't want attention, so she ignores everyone and goes her own way. When Saiki realizes that he can't read her mind, he starts to find out more about her as they become friends. Kaidou, of course, is all over her! Nendou doesn't care, and all of Saiki's other friends like her as well. They don't realize, though, that they have the second most dangerous weapon. Can Saiki find out how to stop her before it's too late? Can she help him? What will happen?
