Dia

Dia is Amu Hinamori's Guardian Character. She was the fourth to be born.

For a while, Dia was turned into an X-Character whe Amu didn't like the changes that came with Spring. She later removed her X when Amu believed in her own radiance, even when she was in a tough situation.

For Shugo Chara! and Shugo Chara!! Doki! Dia only came out of her egg when Amu believed in her radiance. However, in Shugo Chara!!! Party!, Dia was out of her egg the whole time, except when she was sleeping.
