With only a week to go until New Year's, Uryu leaves Amagami Shrine to spend a few days at Kiseki-En Foster Home for some intensive study. But while there, he gets some strange texts from Yuna...and when he rushes back to the Shrine to investigate, he finds a little girl in her place! And in exchange, the present-day Yuna finds herself at the Amagami Shrine of ten years ago...face-to-face with her deceased mother! In the world within the mirror, she must face her past and herself in order to make the connections that will last into the future...
