Everybody thinks Amu is so cool. But that really isn't who she really is. Deep inside, she is shy and a little cynical. One day she wished she could be more true to herself, and the next day she found three eggs in her bed!

Ran, Miki, and Su hatched from the eggs.They are Amu's "Guardian Characters". They say that they are Amu's "true selves", and when Amu Character Changes with them, she can become good at sports, art, or cooking! Soon after they hatched, Amu found herself recruited to become one of the Guardians of Seiyo Elementary.
Now Amu has to fright the evil forces of the Easter Corporation!
