Petite Princess Yucie (ぷちぷり＊ユーシィ, Puchi Puri Yūshī) is an anime series, which was produced by Gainax, aired from 2002 to 2003, and ran for 26 episodes.

There, she experiences many things in her quest to collect the "fragments" of the Eternal Tiara in hopes that she may become the legendary Platinum Princess, who is chosen every 1,000 years.

Yucie is a spunky heroine who is a genius of smiles, and who, despite her common lifestyle, is actually the daughter of a noble and former hero who has retreated from courtly life and lives in the countryside.

Strangely enough, the five candidates Yucie, Glenda, Elmina, Cocoloo and Beth are representatives of these five existing worlds in this story's universe.

Blindly pursuing what is her heart's lifelong desire, to finally grow up and be treated and respected like an adult, Yucie must prove her worthiness to the Tiara and sets out to do many odd jobs as part of the academy's special Curriculum (NOTE: community service) for the candidates, such as tending flowers, babysitting a giant fluff ball, helping to run an old church, helping to run a bakery, and overseeing a kindergarten picnic.

The viewers later discover that all the candidates are under the same 10-year-old "curse" and their rivalry quickly turns into admiration for one another's determination in reaching their common goal.

The girls are resolved in helping their friend and saving the Fairy Realm by defeating the ancient evil Diablo who threatens the existence of all the worlds.

With the combined help of their stewards and friends, the girls succeed with the power they obtained as candidates, but the prince is badly injured.

Upon entering the place of judgment, Yucie and her friends meet a mysterious figure, wrapped in a tattered brown cloak.

Yucie refuses to accept the Tiara when she learns this, and tells the others she is determined to save the Prince some other way, as she cannot sacrifice her friends in the process.

After careful thought, Glenda, Cocoloo, Elmina, and Beth ask the judge to erase Yucie's memories of them, so that she can return to the Human Realm in time to save the prince.

The Eternal Tiara disappears after its owner makes her wish, its immense power quelled by Yucie's strength of heart, and history repeats itself.

With the help of the fathers of the missing girls, he opens the gateway to the place of judgment so Yucie and Prince Arrow can retrieve what was lost.
