Kinkan-chou is a circular shape town with castle-walls surrounding it. With its calm scenery including a park, a theatre, lines of shops, it looks as if just any ordinary town... but why is it a slightly unusual? The people who live there are all nice, but these are including cats, crocodiles, all of which can speak!
In this town, there is a large performing arts school, Kinkan-gakuen, where a girl named Ahiru learns ballet. She is a little clumsy but tries as hard as anyone else, and is always scolded and made fun of but also loved by her friends, Pike and Ririe.
Ahiru has an upperclassman, a boy whom she is fond of, Myuto. He is very good at dancing, not so talkative, but handsome; he is Ahiru`s Prince. However, Ahiru feels Myuto`s eyes look lonely. Just once, she would love to see her Prince smile! With those wishes in mind, she continues to work hard with her ballet lessons. But Myuto has a very beautiful, smart girlfriend Ru, who is even better than her at dance. To think that someone like herself would be able to dance with Myuto is just a dream in another dream. Will Ahiru be able to become a Princess and dance with her Prince?
