Jade of Bango

An ordinary highschool girl, Lin Seonu, who is actually a woman saint holding the 'Jade of Bango', the power of ancient times, however she does not recognize that she 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 Lin. His name is In Mu, who says to her that he is her fiance.
