Uno Uzume may just be your typical second year middle school student, but one day something happens that turns her life around completely. She gets hold of some mysterious cards that can materialize mysterious girls called Fantasista Dolls! Uzume becomes a card master, and forms a contract with five dolls, each with their own unique personalities.

But then a battle begins that could mean trouble for not only the city she lives in, but the entire world... and she is the only that can stop it now! Even though she may think it's impossible for her, she can't do anything to get out of it now! She must fight using various combinations of cards - different weapons, costumes and even events which will allow her to fight. Not to mention that each of the dolls also keeps coming up with strangely cute demands of her!

Will Uzume be able to save the world? For that sake will she even be able to protect herself?!
