3x1 - Shugo Chara!

Amu and her Guardian Characters are on their way to school when they see a girl taking water to a flower. Amu comments on how kind that is. The girl gets flustered, and trips and almost crushes the flower, to be saved by Amu. The two introduce themselves. The girl's name is Rikka and she just transferred to Seiyo. Amu gets surprised when she's able to see Ran, Miki, Su, and Diamond. On the way to school, Amu and co. try to explain everything to Rikka, who lost attention while seeing a butterfly. In the Royal Garden, Amu tells the Guardians about her meeting with Rikka. Then, commotion starts outside and the Guardians check it out. Rikka is trying to save a cat from a tree branch. The branch breaks, and Rikka clutches the cat in fear as she falls.
