Chima Nagatsu, a high school sophomore, has always been able to see spirits that have died but haven’t passed on yet. She also has the power to banish them. One day she gets a job from her uncle asking her to banish the spirits in an all boys school. She reluctantly accepts only to find that one of the spirits, Tsukasa, is a boy whom she admires!
