Yusuke Oramichi, 14, seems to be the worst student in his class in a long time. Perhaps things could change after Yossuki was a rogue student and fought many battles with his colleagues. Things really turn out after Yusuke died in order to save a small boy from traffic. Because of this self-act by Yusuke, he will pass through a new ordeal through which he becomes a spiritual detective who is engaged in several new experiments.
