Shugo Chara / Shugo Chara Doki

..... Amu Hinamori .....

Amu Hinamori (日奈森 あむ, Hinamori Amu?), the series' protagonist, is a student of Seiyo Elementary. Amu's classmates see her as "cool and spicy", but Amu's 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.

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. Throughout the first half of the series, Amu had a crush on Tadase and blushed everytime she was in his presence. She initially regarded Ikuto as a jerk and pervert, but she grew close to him as he aided her countless times. When Ikuto first confesses his love to her, she thinks he is teasing her and dismisses it. When Tadase asks Amu if it is okay for him to fall in love with her, she is thrilled at the progress in their relationship but soon finds herself drawn to Ikuto. She was saddened when Ikuto decided to leave in search of his father. Because of this, she realizes that she truly loves Ikuto. After he confesses to her and kisses her close to the lips, she refuses to admit her feelings for him, which prompts Ikuto to make a deal with her that he will get her to fall in love with him. In chapter 48, Amu confesses to Tsukasa that she had liked Ikuto for his outer character and his inner character Although they have a much better relationship than before, Amu remains stubborn about her feelings for him. Amu's primary rival is Utau Hoshina, Ikuto's younger sister who is jealous that Ikuto shows an interest in Amu instead of her. They soon become good friends after Utau leaves Easter.

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.

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, Dia 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. She finally comes to terms with the loss of her Guardian Characters at the end of the journey, however as she returns she realizes that she has Ran, Miki, Su and Diamond back in Egg form much to her relief and later joy as they born gain later in Shugo Chara Encore. In the anime television series, Amu is voiced by Kanae Itō. She is portrayed by Yuuka Maeda in the musical.

In chapter 38, Ran undergoes a new Character Transformation, along with Miki, Su, and Diamond; becoming Amulet Fortune. In chapter 44, she disappears along with Miki and Su, and later Diamond as well when Amu no longer needs them.

.....Miki.....

Amu's blue egg. The second Guardian Character to hatch is Miki. Miki represents Amu's desire to be more sharp, level headed, and artistic. Miki is also the one to help Amu make fashion choices. Reflecting Amu's love interests, Miki has shown an interest in Tadase's Guardian Character, Kiseki, Ikuto's Guardian Character, Yoru, Kukai's Guardian Character, Daichi, and Nagihiko's Guardian Character, Rhythm. During Character Change, Amu gains increased artistic abilities. During Character Transformation, Amu becomes Amulet Spade.

.....Dia.....

Amu's yellow egg. Dia is Amu's fourth Guardian Character. Dia represents Amu's radiance. Unlike most Guardian Characters, she is supposedly the most powerful. She becomes an X Egg when Amu dislikes all the changes that were happening in the spring. While collecting X Eggs with Yukari, Utau finds Diamond's egg inside the box. She soon hatches into a X Character. Unusually, she is not shaped like the usual X Character; she looks like a normal Guardian Character, but with a white X-shaped clip covering her black diamond-shaped clip. Because of this, Amu doesn't know Dia's true name. Utau uses X-Dia to extract heart's egg of other people by character changing with her. X-Dia can Character Transform with Utau, becoming Dark Jewel, however, the transformation does not last very long. When Amu is finally able to prove to Dia that she does have enough confidence to shine she reverts into her true original form. Together they undergo a Character Transformation, becoming Amulet Diamond. Afterward, Dia returns to her egg until she sees that Amu "shines again", but secretly comes out as a spirit at times.

Dia becomes Amu's guide in the Eggs' Cradle in Amu's search for the four colored shards. Coming to terms with herself and the future, Amu accepts the loss of her Guardian Characters and Dia disappears as well, guaranteeing that the four of them will always be watching over her. In Shugo Chara Encore Dia and the other three have hatched again and save Amu's catching of the thrown bouquet. When Amu Character Changes with Dia in Shugo Chara Party's Shugo Chara Dokki Doki, Amu doesn't really do much but smile and sparkle, disappointing Ran, Miki, and Su. It should be noted that she only does this in the anime. It is unknown what her character change really does since the manga has never shown. Just like Amu, she is voiced by Kanae Itō.

.....Ikuto Tsukiyomi.....

Ikuto Tsukiyomi (月詠 イクト, Tsukiyomi Ikuto?) is a teenage boy in high school, contracted by Easter to find the Embryo. He often helps Amu even though he works for Easter. Ikuto actually despises Easter and tries to wrench himself free from them by trying to find the Embryo to grant that wish. He possesses the Dumpty Key which pairs with Amu's Humpty Lock which at first did not fit in the keyhole. Like his father, Ikuto is a skilled violinist. He is the current owner of the Dumpty Key, which originally belonged to Aruto, his father, although Tadase's father had it for a little while. His father is presumed to be dead, but Ikuto refuses to believe it and has set out on finding him. His mother was forced to marry the president of the Easter Company after her husband's violin was found in a foreign country. From her second marriage, she bound her children into working for Easter.

In chapter 43, Ikuto confesses to Amu he will never see her again as he is going to search for his father. At the airport, when Amu shows up to see him, he tells her that he loves her and kisses her close to the lips, and tells her that he will make her fall in love with him. Ikuto returns for Yukari Sanjo and Yuu Nikaidou's wedding. He promises that he would show Amu sides of him that she has not seen, but only when he returns for her when she is older.
