SHUGO CHARA! (Shugo Kyara!), by Peach Pit. First published in 2006 and first published in North America in 2007.
PLOT:
Amu has a reputation for being a cool, badass sort of girl, but Amu has no idea where it came from. She doesn't see herself as cool and aloof, but instead as painfully shy. She wants to be more assertive with people, particularly where the handsome class president Hotori Tadase is concerned. Her salvation comes in the form of three magical eggs, with each containing a doll-like creature known as a Guardian Character. Under their influence, Amu finds she can do anything and discovers that she is not the only one to possess Guardian Characters. She also soon learns that there are others who covet the Characters and their powers for themselves and that she must fight to protect them from these mysterious (and sometimes cat-eared) figures.
