Amu Hinamori (日奈森 あむ, Hinamori Amu), the series' protagonist, is a student at Seiyo Elementary School. Amu's classmates see her as "cool and spicy". She can be identified as a tsundere (cold and mean to opening up to other people), but her true character is shy and timid. Part of the reason for this misunderstanding is the trendy punk goth clothing her mother buys for her as well as the way she expresses her shyness. However, when Amu wishes for the courage to become her would-be self, three colorful eggs appear. When they hatch, they reveal Amu's Guardian Characters: Ran, Miki, and Su.
