Beautiful and young, Ayami has a solid reputation as a dedicated and reliable elementary teacher, but her true character is solely clandestine. Ayami does not believe in love and trust, and her values make her oblivious to other people's matters. Almost devious, she is always scheming so she never has to deal with responsibility and troubles that spur around her. One day, a new student Yuiko enrolls in her homeroom class. It does not take long for Ayami to find out that Yuiko has an ability to predict the future through the dreams she sees in her sleep; dreams which are symbolic and require proper interpretation to understand the upcoming occurrences. But when Yuiko begins to have nightmares of people around them, Ayami, though unwillingly, must team up with Yuiko to try to change the tragic fate of those around them... But can they properly assess what Yuiko's nightmares truly mean and change what may already be destined?
