[The Story]
Deemo is a mysterious being who lives alone in a castle, playing the piano to itself.

Deemo feels compelled to help her get home to her world.
While looking for a way to return her to the sky, Deemo notices a small sapling which grows the more music is played.
If Deemo is able to make it grow into a tree, tall enough so it would reach the window in the ceiling, she may just be able to get home.

As the two interact, Deemo learns what it means to have a friend.
What awaits the two when the little girl regains her memory?
This is a slightly strange, touching tale――
