Amu becomes a member of the Guardians, the school's student council, and discovers that each member has a Guardian Character. Amu's position with the Guardians is the Joker. Her task as the Joker is to search for and purify X Eggs and X Characters (also, in the second season, she purifies Mystery Eggs, the corrupted forms of people's would-be selves). Ran, Miki, and Su help Amu with her task through a process called Character Transformation, which is enabled by the Humpty Lock and grants Amu special abilities depending on the Guardian Character. Later on, Amu also creates a fourth egg, known as Diamond. In the second season, when Amu shows her true potential, the Humpty Lock increases in power. Thus, new transformation scenes are used.
Amu's two main love interests are Tadase Hotori and Ikuto Tsukiyomi. Amu's primary rival is Utau Hoshina, an idol singer for Easter who is jealous that Ikuto shows an interest in Amu instead of her.
Amu gains the Dumpty Key from Yoru and uses it to unlock the Humpty Lock. In some of the later chapters, when Amu opens the Humpty Lock with the Dumpty Key, she and Tadase see more of Ikuto's past. Their journey ends when Amu Character Transforms with Diamond, and she and Ikuto fight briefly. Ran, Miki, Su, and Diamond all combine their powers, making Amu Character Transform into Amulet Fortune and Ikuto Character Transforms into Seven Seas Treasure.
In the latest chapters, after defeating Gozen and saving Ikuto, Amu's feelings for Ikuto are shown more clearly. When he reveals he is leaving, Amu begins crying and runs away showing she does indeed feel strongly about him. At the airport, before he leaves, she runs after him, to which Ikuto responds with kissing her on the cheek - very close to the lips - and confessing his love. Amu remains stubborn and does not openly return his feelings. However, Ikuto promises her he'll make her fall for him, as she promises she will find her true self.
Amu ventures to the Eggs' Cradle, a place where unborn and "lost" Shugo Chara reside, in order to search for four coloured shards representing each of her Shugo Chara in an attempt to bring Ran, Miki and Su back. In chapter 44, Diamond tells Amu that Ran, Miki and Su have "disappeared" and that she will help Amu find them as her "navigator". Diamond becomes Amu's guide in the Eggs' Cradle in Amu's search for the four coloured shards. With her help, Amu realizes that she loves Ikuto as she managed to "go through" her heart while she only likes Tadase for his "outer" character. She finally comes to terms with the loss of her Guardian Characters at the end of the story. In the anime television series, Amu is voiced by Kanae Itō. She is portrayed by Yuuka Maeda in the musical.
