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. Using this power to look at other students' answers during exams, Yuu manages to enter a prestigious 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, 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. Yuu attempts to flee but is caught by Jōjirō Takajō, who can move at uncontrollably high speeds. Nao, who can make herself invisible to a specific target, beats up Yuu. Afterwards she arranges for him and his little sister Ayumi to be transferred to Hoshinoumi Academy, a school for those with abilities like him. Getting dumped by Yumi as a result of the restrictions forced upon him, Yuu reluctantly prepares for his new life as a member of Hoshonoumi Academy's Student Council.
