A Book of Dreams

An ordinary highschool girl, SEONWU Rin, who is actually a woman saint holding the 'Jade of Bango', the power of ancient times, however she does not recognize that shie is a woman saint. On her seventeenth birthday, she can obtain special eyesight seeing the ghosts and she goes to school every morning with the harmless and lovely ghosts. One day, however, she has an abnormal dream, and that evening, she encounters a terrible evil spirit. She is shivering in horror, but in the very nick of time a handsome man she had seen in a dream appears to rescue her and he frees the ridiculous power that had been concealed in SEONWO Rin. His name is In-Mu, who says to her that he is her fiance.
