Keitarou Gentouga is a college freshman who despises ghosts. Unfortunately for him, he possesses a knack for attracting spirits. Two years ago, this affinity resulted in him sustaining a spiritual injury to his right hand, with his friend caught in the crossfire. The incident caused him to become a shut-in, leaving him with very poor social skills. Fortunately, Keitarou is slowly beginning to re-enter society, thanks to the assistance of his childhood friend, Eiko Houzuki. As part of his rehabilitation, Keitarou takes on a part-time job as a private tutor, and his first student is none other than Eiko's cousin, Yayoi Houzuki. In addition to being a child prodigy, Yayoi has another peculiarity—she possesses a spiritual constitution, just like Keitarou. However, unlike Keitarou, she yearns to encounter spirits, hoping to find the ghost that took her mother away. As Keitarou is dragged along by Yayoi and Eiko to haunted locations, his part-time job seems to be drifting further and further from its original purpose.
