When Keitarou Gentouga started college, he had a firm dislike for ghosts. Unfortunately for him, he attracts them like a magnet. In fact, two years ago, a spirit caused him and his friend harm, leaving Keitarou a recluse with no social skills. But his friend Eiko Houzuki has been helping him slowly reintegrate back into society. To aid his recovery, Keitarou starts tutoring and his first pupil is Eiko's cousin, the intelligent Yayoi Houzuki, who also shares Keitarou's ability to sense ghosts. However, unlike Keitarou, Yayoi is eager to seek out ghosts in hopes of finding the one responsible for her mother's death. Despite Keitarou's aversion to ghosts, Eiko and Yayoi persist in taking him to haunted places, causing his tutoring duties to take a backseat.
