Amu Hinamori is a student at Seiyo Elementary, where she has a reputation for being super cool and Stylish. Amu’s real personality is in contrast very shy, and one night she makes a wish that she would have the courage to show be her “real” self.
The next morning Amu finds three brightly coloured eggs, each one eventually hatching into a Guardian Character, angel-like beings able to give Amu a temporary change in personality. With the Guardian Characters, Amu’s life becomes much more complex as she now struggles to deal with her new personalities and the Seiyo Elementary Guardians – a student council group where each member owns their own Guardian Character.
Everyone at Seiyo Elementary thinks Hinamori Amu is the coolest girl in class. But, she’s nothing like that. Amu’s actually a very shy girl who wishes to have courage to truly be herself.
One morning, she found three mysterious, little eggs in her bed. Each egg contains a “Guardian Character“.

Because of this, he does not do Chara Change with Kiseki unless it’s absolutely necessary. Actually, he too is a shy person and is not a public speaker. So he wished to become stronger and become another character, much like Amu.
