I LOVE shugo chara! and no... its not because there are two cute guys in it! (Kukai and Ikuto) Although the eye-candy makes the anime much more watchable. I like it much more due to it's message, to follow your dreams and to be yourself. Always aspire and do something you are passionate about, but if you are too hard on yourself, you'll never be able to do anything.
Shugo chara starts off with a girl named Amu, who is perceived as "cool and spicy", even though no one is America would be caught dead calling someone spicy... but she does not feel that way, and would like to be her own person. But if she does, her classmates might be upset as she will change the status quo. And here comes the eggs, she gets three guardian characters (shugo chara) to help her reach her potential. Amu's abilities increase when she "character changes", but that is just her potential, she still has to learn her skills outside of the chararter changes.
She meets up with other people who have guardian characters and has to ward off the X-egg's, which is what becomes of the eggs in peoples heart when they are depressed. She also has to prevent the bad guys from achieving the embryo, which is a egg that will grant you a wish.
