There is a group at Seiyo called 'The Guardians'. The Kings Chair, Tadase Hotori, is the one Amu has a crush on. The rest of the Guardians' names are: Nadeshiko Fujisaki, Queen's Chair; Kuukai Souma: Jack's Chair; and Ace Chair: Yaya Yuiki.

Her first Shugo Chara to be born is Ran. Ran is really girly, and she's very good at sports. Amu's first character change with Ran is at a school assembly later on. She sees the prince and feels bad about what she did earlier, and she thinks he's very cute. Ran turns Amu into a not so honest girl, into an honest girl. So then Ran character changes with Amu and Amu 'confesses' that she really loves Tadase.

The second Shugo Chara to be born is Miki. She's a little tomboyish, and she's a very good artist and has an artistic talent. Miki's first character change with Amu is when Amu and Ran go to Amu's art class, and Amu is forced to draw a picture of Yamabuki Saaya and the drawing looks horrible.
