The secret of the violin! Notes dancing in the wind!
Amu runs home and encounters Ikuto playing his violin. While Ikuto plays, Amu sings until one of the violin's strings breaks. Having no spare string, Ikuto and Amu go to a violin shop for repairs. At the shop, Amu meets Kotone, who has a crush on Ikuto and aspires to be a violin artisan. Another customer stops in and drops off two violins for repair, one of which the customer asks Kotone to repair. Kotone diligently works on the violin. After finishing, Kotone falls asleep, but knocks over a cup and spills tea onto the violin. When she wakes, Kotone notices that the tea has soaked into the violin's frame, panics, and runs off with the violin. When Amu finds Kotone, an X Egg emerges and hatches. Amu transforms with Miki and purifies the X Character. With encouragement from her father and the customer, Kotone continues repairing the violin.

Shugo Chara!
Amu Hinamori is a 5th grade transfer student who is fashionably cool, tough and independent. Despite this, she is also a girl who seems unapproachable, both at home and at school. In reality, the "Cool and Spicy" role she plays is just a facade that she unconsciously plays. With her guardian characters, she fights the Easter Company who is extracting people's eggs to create X Eggs & X Characters in search of a special egg called the Embryo.
