Yuu Otosaka is a boy who wakes up one day and finds that he has the ability to temporarily possess anyone in his line of sight for five seconds. Using this power to look at other students' answers during exams, Yuu manages to enter the prestigious Hinomori High School, where he once again uses his ability to woo the school's madonna, Yumi Shirayanagi. However, Yuu's perfect scores catch the attention of the student council president, Yoshiyuki Omura, who challenges him to take the exam again or else face expulsion on grounds of cheating. This turns out to be a trap set up by a girl named Nao Tomori, who had been observing his abilities in action.
