This piece was produced as a pilot film for a theater movie and was not actually released at theaters. Although it turned out to be an excellent piece of work, it had little public exposure until it came out in video. The original story, "Black rain and white feather" comes from the story serialized in a magazine called Ririka. All the staff worked very hard to make this beautiful work. In the story, Unico tries to restore the blue sky for a sick girl in a city where the sun has lost light due to factory smoke.
