Amu Hinamori has a reputation for being "cool and spicy"; however, her real personality is that of an extremely shy and easily intimidated girl. One night Amu makes a wish that she would have the courage to be reborn as her "would-be" self. The next morning Amu finds three brightly colored eggs red, blue, and green in her bed. Each egg eventually hatches into a Guardian Character: Ran, Miki, and Su. Guardian Characters are tiny beings that aid a person into becoming their "would-be" selves and fulfill the person's dreams. The Guardian Characters accomplish this by giving encouragement and advice, but they can also temporarily change a person's personality and abilities. With the Guardian Characters, Amu's life becomes much more complex as she now struggles to deal with her new personalities and the Seiyo Academy Guardians a student council group where each member has their own Guardian Character who recruits Amu to search for and seal the X eggs and X Characters, which are the corrupted forms of people's dreams.
