While a girl named Hinako moves away, her Guardian Egg drops out from her package. Amu notices this and picks it up on her way to the Royal Garden. She, Kukai, and the Guardians discuss and decide to find the owner of the egg.

The egg eventually hatches to reveal Kiran, Hinako's Guardian Character. The Guardian Characters go places, having fun, helping out others, and try to find Kiran's owner. Yoru, Il, and El later come and decide to help. They eventually find Kiran's owner and part ways after Hinako is troubled, hurting Kiran. Amu gets a text message from Utau, telling her where to find her Guardian Characters. She eventually meets up with the rest of the Guardians.
