Without realizing it, Kimihiro Watanuki has purchased a dream. According to his boss Yuko Ishikawa, the mysterious time-space witch, people usually buy good dreams-but Kimihiro's dream is a man-eating nightmare. Even worse, it has come true. Then Kimihiro meets a wistful girl who, like him, can see the spirit world. Together they try to prevent a harmless ghost from being exorcised from its beloved resting place, an ancient cherry tree. The girl's mother wants her to have nothing to do with Kimihiro, but the spirits say otherwise.
