Amu Hinamori (日奈森 亜夢, Hinamori Amu?)

• Character Transformations: Amulet Heart (Ran), Amulet Spade (Miki), Amulet Clover (Suu)
  

Amu Hinamori, the series protagonist, is student of Seiyo Elementary (fifth grade at start of story). Amu was seen as a cool and stylish girl and has become popular at school but what she really is is just a shy, gentle, and extremely normal girl. The main reason for this misunderstanding is the trendy punk and gothic lolita clothing her mother buys for her. One night she wished she was not the type of person she currently was, and on the next morning, three Guardian Eggs appeared. During Character Change and Character Transformation her hair clip changes (Ran→Heart, Miki→Spade, Suu→Clover) The characters Amu becomes are good at certain activities like Amulet Heart who is athletic, Amulet Spade who is artistic, Amulet Clover who is a skilled house-worker or maid, and Amulet Diamond who is a musician.

Amu has a crush on Tadase Hotori, the King's Chair of Seiyo Elementary's Guardians. However, when she confessed her feelings during her first Character Change with Ran in front of the entire school, Tadase refused her. Amu later learns that Tadase is not good a receiving confessions and would Character Change with Kiseki, who would refuse the confession. At first, Amu rejects the offer to join the Guardians, using the excuse that she does not want to wear the royal cape. But the Guardians announce her as a member anyways under a special position, Joker's Chair. On joining the Guardians, she receives the "Humpty Lock", a locket with a four leaf clover decoration. Nadeshiko states that the very first king left it and said, "Entrust this to the joker whom comes with three Guardian Eggs." Later on, it was explained to her that the Joker's duty is to hunt X eggs.

It is seen that Amu has a crush on Ikuto as whenever he touches her, she blushes which she does not realizes at first but began to be aware of. In volume 5, Amu goes on a date with Tadase, which shows a little bit more development of their relationship. She also was confronted by Ikuto, on her date, resulting to a confession from Ikuto saying the actual reason he bothers her is because he is interested in her. This is also shown as Miki liking Kiseki and Yoru, but liking Yoru seemingly more.
