Saga is a tidy young girl, living an ordinary life with her grandmother in a pleasant small town. One day she comes across a tiny pink-haired creature who seems to be ill. Thinking it might be hungry, Saga feeds it and brings it home.
The creature turns out to be snow fairy apprentice Sugar, a hyperactive, cheerful little fairy with magical skills and the ability to make snow...and she can only be seen by Saga! Now, what is Saga going to do with such a whimsical little thing invading her well-planned life, and will Sugar ever accomplish what she came to the human world for?
