The demon tells her she has something it wants and that she must travel back in time through a mirror in order to rescue Joey. On the other side of the mirror, in the world of the past, Rena uncovers many secrets and discovers she is more connected to that world than she could have known. With the help of a new friend, one whom she is inexplicably drawn to, she embarks on a journey to find her brother. But she soon learns that her companion may have a mysterious connection to her own past.
