Fandisc of Garnet Cradle.

When she wakes up, she finds herself being in a crystal ball.... She is very very small and confined in a hard ball.... There is a prince in front of her. He is surprised to see her, but he doesn't know what's going on.... A messenger suddenly appears in front of them and tells them that she is confined in the ball because the prince did something extremely evil.... The messenger also says him, "If you want to save her, you'll need to complete a Christmas tree that is one and only in the world. If you can't, she will be confined in the ball forever...."
