This story takes place before the events of the first movie and tells a different tale.

It had been almost two long years since Sunset had stepped through the magic mirror and entered this strange world. To her disillusionment, there was also a Hearth Warming Eve holiday in this world, which the humans called Christmas.
It was the last day of school before Christmas Eve and Sunset was already preparing to break the Christmas spirit of her classmates next year. But this year, the spirits had other plans for her.
