What happens in the end of shugo chara and who marry amu?

In the end of Shugo Chara!, Amu Hinamori doesn't marry anyone. The series focuses on her journey of self-discovery and growth, with her romantic relationships playing a secondary role.

Here's what happens:

* Amu's feelings become clear: She realizes her true feelings for Ikuto Tsukiyomi, but he chooses to leave with his father to travel the world.

* Open ending for romance: The series ends with Amu and her friends moving on to high school, leaving their romantic possibilities open.

* Focus on growth and friendship: The final arc of the series focuses on Amu's self-acceptance and her strong friendships with Tadase Hotori, Nadeshiko Fujisaki, and the others.

While there's no explicit marriage, the anime does hint at the possibility of a future relationship between Amu and Ikuto. However, the series ultimately emphasizes the importance of personal growth and friendship over romantic relationships.
