Main characters
Amu Hinamori
, 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. 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 main love interests are Tadase Hotori and Tsukiyomi Ikuto. Throughout the first half of the series, Amu has a crush on Tadase and blushes every time she is 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 him. 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 is saddened when Ikuto decides 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 Tadase's older self that she had liked him for his outer character. Although they have a much better relationship than before, Amu remains stubborn about her feelings for Ikuto. In the final chapter of ''Shugo Chara Encore'', she is happy to reunite with him and is seen holding hands with him at Sanjou and Nikaidou's wedding. 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 the Amu Character transforms with Diamond, and she and Ikuto fight briefly. Ran, Miki, Su, and Diamond all combine their powers, making the Amu character transform into Amulet Fortune and the Ikuto character transform into Seven Seas Treasure. Amu ventures to the Eggs' Cradle, a place where unborn and "lost" Shugo Chara reside, 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. 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 are born again later in ''Shugo Chara! Encore''. She is portrayed by Yuuka Maeda in the musical. ; : Ran is the first to hatch from Amu's eggs and represents her desire to be more honest, confident and athletic. Ran is frequently cheering Amu on. During Character Change, Amu gains increased athletic abilities. During Character Transformation, Amu becomes Amulet Heart, with a cheerleader inspired outfit. 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. In ''Shugo Chara! Encore'' at the very end of the last chapter, she and Amu's other Shugo Chara emerge and hatch again at Sanjou and Nikaidou's wedding much to Amu's joy. ; : The second Guardian Character to hatch is Miki. Miki represents Amu's desire to be sharper, level headed, and artistic. Miki also helps 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. In chapter 38, Miki undergoes a new Character Transformation with Ran, Su, and Diamond becoming Amulet Fortune. In ''Shugo Chara! Doki'', Miki is the only one of Amu's Guardian Characters to be able to sense Mystery Eggs clearly. In chapter 44, she disappears along with Ran and Su, and later Diamond as well when Amu no longer needs them. In ''Shugo Chara Encore'', she returns along with the others and together they catch the wedding bouquet for Amu who accidentally threw it back in the air again. ; : The third Guardian Character, Su, represents Amu's desire to be more caring, sensitive and improve her domestic skills. However, Su is prone to silly mistakes. She is very fond of Amu's teacher, Yuu Nikaidou. Amu cooking and cleaning skills improve during Character Change. She also becomes "too girly". During Character Transformation, Amu becomes Amulet Clover with an outfit just like Su's. In chapter 38, Su undergoes a new Character Transformation with Ran, Miki, and Diamond becoming Amulet Fortune. In chapter 44, she disappears along with Miki and Ran, and later Diamond as well when Amu no longer needs them. She and the others make an unexpected return toward the end of the last chapter of ''Shugo Chara Encore'' as they appear to be reborn again from Amu's feelings. ; : Diamond is Amu's fourth Guardian Character. Diamond represents Amu's desire to calmer and more optimistic. She is shown to be an air-headed character who always speaks with a soft voice. In Japanese versions, her name is shortened to Dia. She is a unique Guardian Character, who only appears and uses her powers when she senses Amu's strong desire to help others. Before hatching, she became an X Egg and left after Amu lost confidence in adjusting to the changes happening in the spring semester. Her egg is later found by Utau, while collecting X Eggs with Yukari. 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 does not know her true name. X-Diamond is able to character change with Utau to extract more X-eggs from people. They can also Character Transform with Utau, becoming Dark Jewel, however, the transformation does not last very long. When Amu is finally able to prove to Diamond 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, Diamond returns to her egg until Amu's desires to "shine again", but secretly comes out as a spirit at times. In chapter 38, Diamond finally returns and helps Amu to lift Ikuto's spirit. They then character transform and help Ikuto, She, Ran, Miki, and Su combine powers with Amu becoming Amulet Fortune. 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 colored shards. Coming to terms with herself and the future, Amu accepts the loss of her Guardian Characters and Diamond disappears as well, guaranteeing that the four of them will always be watching over her. In ''Shugo Chara! Encore'', Diamond and the other three have hatched again and catch Amu's thrown bouquet. When Amu Character Changes with Diamond in ''Shugo Chara! Party's Shugo'' Chara Dokki Doki, Amu does not really do much but smile and sparkle, disappointing Ran, Miki, and Su.Tadase Hotori

Like Amu, he is actually a shy person and is not good at public speaking; instead, he Character Changes with his Guardian Character, Kiseki. Although he is popular with the girls, when a girl confesses their love to Tadase, he will have Kiseki reject her. However, whenever he hears the word ''ouji'' ("prince"), or anything resembling the word ''ouji'', he Character Changes into an egotistical king who seeks world domination. Amu develops a crush on Tadase soon after she transfers to the school. His love interest is Amulet Heart, Amu's Character Transformation with Ran, but it later becomes Amu herself. In episode 39, Kiseki's egg turns into an X Egg because Tadase lost his self-esteem by not being able to find the ''Embryo''. With the help of Amulet Heart, Tadase turns back to normal. Tadase has known Ikuto and Utau since childhood, but he does not talk about it in detail until the Guardians are about to face Utau in their final battle. Amu and Tadase reconcile soon after, though. Later on, he agrees to help Amu save Ikuto from Easter. Tadase confesses his love for Amu in chapter 28 (episode 74 in the anime) behind Amu's house while Ikuto is hiding in Amu's closet.

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 to find him.

In chapter 43, Ikuto confesses to Amu he will never see her again as he is going to search for his father. Ikuto returns for Yukari Sanjo and Yuu Nikaidou's wedding.
