"Ratirica" is a magical tiara with hidden powers, that has been passed down through the generations of the royal family. Upon being rejected by Ratirica, Princess Caroria fails her succession ceremony. During the following two months, she must train herself until the next succession ceremony occurs, in the hopes of being accepted by Ratirica.
With the help of Norn, a Shinto priest, she is also able to explore other kingdoms and befriend the various princes that she meets.
