Welcome to Gaia! ::

Tadase Hotori!..The KING 8D. Well actually..not really.

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 into the school. His love interest is Amulet Heart, Amu's Character Transformation with Ran! sad eh? =_=

ANYWAY his Chara is Kiseki is Tadase's Guardian Character. Kiseki was born for a combination of Tadase's desire to be stronger and the dream of world domination. Because of this, Kiseki is extremely egotistical and often demanding, and doesn't like obeying others. He frequently calls other Guardian Characters to go on "Special Secret Meetings." A running gag is that the other Guardian Characters will almost always ignore him when he starts up a meeting. Kiseki is aware of Tadase's crush on Amu and acts the same way as Amu's Guardian Characters whenever Tadase seems to be confessing to Amu. Kiseki holds a grudge against Ikuto's Guardian Character, Yoru. During Character Change, Tadase gains the confidence to overcome his shyness. However, sometimes Tadase will become an egotistical person who seeks world domination.! MWAHAHAHA

Tadase's transformation character

Ikuto Tsukiyomi

Ikuto is a teenage boy ..much older then the other characters .Older then Amu! 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 his own 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. The Dumpty Key used to belong to him, but the Dumpty Key is believed to belong to Tadase's father, but it actually belongs to Aruto, Ikuto's father. His mother, upon marrying someone else after they found her husband's violin in a foreign country and believing that he would not come back, bound her children into working for Easter. Ikuto's personality is aloof, stoic, and a little naughty. He likes teasing people, especially Amu and Tadase. He is also the older brother of Utau Hoshina. As the series goes on, he grows very strong feelings for Amu — he confessed that he loves her in the same chapter Tadase did, although she believes that he is teasing her. He later surrendered himself to Easter, not wanting to get anyone else involved in the mess he made. In the manga timeline, it is shown he Character Transformed with a new black Guardian Egg to become Death Rebel, shocking Amu. In chapter 37, Tsukasa told Ikuto he resembles his father when he yells. In chapter 38, he Character Transforms with Yoru and the black egg into Seven Seas Treasure. In chapter 39, it's said that Ikuto may have two eggs, one is possibly still inside him. In one of the later chapters, Ikuto calls Amu 'princess' and she replies by asking him to thank her for making him get back to normal. Ikuto swears that this time he will be the one to protect her

Yoru
Yoru is Ikuto's cat-like Guardian Character and represents Ikuto's desire to be free. Yoru often goes out by himself and enjoys causing trouble for the Guardians and their Guardian Characters for fun. When Ikuto and Yoru undergo a Character Transformation, they become Black Lynx. Yoru is hysterical when Ikuto does the Death Rebel Character Transformation

Death Rebel

Nadeshiko Fujisaki
Nadeshiko Fujisaki is a student in the same year as Amu and serves as Queen's Chair of the Guardians. When Amu rejected the offer to join the Guardians, Nadeshiko tries several tactics to convince Amu to join. The two become best friends and Nadeshiko looks over and supports Amu in her love life. However, before Amu and Nadeshiko enter the sixth grade, Nadeshiko leaves Seiyo Elementary for Europe to study dancing.
Nadeshiko is actually a boy named Nagihiko Fujisaki, called "Nagi" as a nickname by Amu and the girls. It is tradition in the Fujisaki family for males to be raised as females as part of their training so that they may play female roles in Japanese dance. Nagihiko's secret is known by his family, Kukai, Tadase, Kiseki, Daichi, the school's principal Tsukasa Amakawa, and Rima. After Kairi leaves the Guardians, Nagihiko returns and is appointed as the interim Jack's Chai

Chara
Temari

Temari is Nagihiko's first Guardian Character. Temari appears to be elegant and Nagihiko's desire to be more mannered and become a Japanese dancer. However, during Character Change, both Temari and Nagihiko (as Nadeshiko) become aggressive and very masculine; Nagihiko, inadvertantly, also gains a naginata, which he promptly uses. Prior to Nagihiko's return to the guardians, Temari went back into her egg to slumber

Rhythm

Rhythm is Nagihiko's second Guardian Character. Rhythm appears to be cool and outgoing, showing Nagihiko's boy self.

Yaya Yuiki

Yaya Yuiki is the childish girl serving as the Ace Chair and is one year junior to Amu. Yaya often acts immature for her age, such as having an enormous sweet tooth, a great soft spot for items like ribbons, as well as tending to be hyperactive. She is also a ballerina, though a rather clumsy one. She has a newborn baby brother named Tsubasa, who, she claims, gets all her parents' attention. It is because of this that her baby-like Guardian Character, Pepe, was born. Though she acts jealous around Tsubasa, Yaya does have a responsible side, once personally taking him to the doctor when he had a fever, as no other option was possible

Pepe

Pepe is a baby-like Guardian Character who was born from Yaya's desire to remain baby-like in nature. When either she or Yaya get hurt or something goes wrong, both of them will begin to whine and cry in unison. During Character Transformation, they become Dear Baby!

Chara transformation

Kairi Sanjo

Kairi Sanjo replaces Kukai as the new Jack's Chair when Kukai leaves for middle school. Kairi is tall, despite being two years junior to Amu. Unlike the spontaneous Kukai, Kairi is uptight, very organized, and blunt about faults. Even with these traits, he is so capable that Amu and Yaya call him "chairman."
Kairi is the younger brother of Yukari Sanjo and was sent to spy on the Guardians. This wasn't his choice though, as Yukari immediately begged him to transfer to Seiyo upon discovering that he had a Guardian Character. Since his sister is busy at work, Kairi takes care of the household work (and his sister) in her apartment. However, when he saw the true meaning of his "missions," he tries to rebel against Yukari, but not before he reveals his secret to the Guardians when they accidentally discover him with Pestering CDs. He switches sides after Amu convinces him he is a good person. Afterward, he leaves saying that he promised his parents and local classmates that he would return, but not before declaring his love for Amu, saying that he shall return for her when he has become a man. He also declared a rivalry toward Tadase. Recently in Chapter 44, he is shown in Amu's town looking for Yukari and comments about also looking for "that person".

Musashi

Kairi's Guardian Character. Musashi has traits and the personality of that of a samurai. He also has some of Kairi's traits, such as green hair and glasses. When he Character Transforms with Kairi, they become Samurai Soul.

Chara transformation

Yukari Sanjo

Yukari Sanjo is a former employee of Easter Company, Kairi Sanjo's older sister, and Utau's manager. She came up with a new project, Black Diamond, to find the Embryo and mass-produce X Eggs. The CDs of the band were freely distributed and the people listening to it had their Eggs removed by force. As the band became more famous, their song is slated to be released to the Internet together with the unveiling of the band.
She and Utau resigned from Easter after Amu got Diamond back, and started their own music industry called Sanjo Productions. Yukari once dated Yuu Nikaidou, but the two have since broken up. She gets annoyed whenever their former relationship is mentioned
