The King of the Cosmos once accidentally destroyed all the stars in the universe. He sent his son, the Prince, to Earth and ordered him to create a large katamari. The Prince rolled the katamari and made the katamari bigger and bigger, rolling up all the things on the earth. The katamari that he created floated in space, sparkling, and brought back the lost starry sky. As the starry sky was restored, the King's fans gradually grew in number all over the world. The King wanted to respond to the wishes of his fans for his success, and the Prince kept rolling the katamari to make everyone's dreams come true.
