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.
