Lonely high school student Kimihiro Watanuki has a secret, he can see ghosts, a gift or a curse he might as well be without. One day, he is drawn to the home of Yuko ichihara, a self-proclaimed dimensional witch who offers to cure him in exchange for an unspecified length of service as her servant. Watanuki and his friends are slowly drawn into a world of ghosts, God and demons, and an endless battle between the forces of positivity and darkness.
