When what appears to be a cluster of shooting stars appears in the sky, Rinko Kougyoku and her friend Minami each make a wish. What the girls actually saw were not stars, but 'Jewel Charms' falling to Earth. These charms were created by three magicians in a magical world named Jewel Land, each housing one of its many native Jewelpets. Although these creatures are free to roam the world in their original form, the magicians sometimes turn them into charms so that they can be carried around with great ease. Most Jewelpets do not find this troublesome, but once a mischievous bunny named Ruby feels overly claustrophobic, she devises her escape. One day, the magicians decide to move the Jewelpets and task a pelican with delivering them to the Dream Forest. All is well until a strong gust of wind disorients the bird, who then drops all the charms he was carrying. Instead of heading towards the Dream Forest, all the Jewelpets but Ruby fall to Rinko's home city on Earth. Someone must go and retrieve them all, and as Ruby was the worst-behaved of the bunch, she is given the task of going to Earth. When Ruby reaches Earth in the form of a red Jewel Charm, she falls into Rinko's water glass, and thus begins a rather unexpected adventure. Rinko, Minami, and Ruby form an alliance to search for and gather all the fallen charms, encountering strange creatures and tons of helpful allies along the way. Will they be able to successfully bring the Jewelpets home safely, or is Earth full of more danger than they had expected?
