I'm Usami Ichika! Myself and the others all decided to take part in a famous sweets contest that's to be held in France♪ But Ciel doesn't seem like herself...so making sweets and transforming into a Cure don't go so well for her!

At the contest venue, we meet a pâtissier called Jean-Pierre. Hang on! This is the same man who taught Ciel how to cook in Paris! Ah! I just had a bright idea☆Ciel should create a memory filled-sweet called "Mille-feuille" together with Jean for the contest! With that all decided, let's・la・cooking...well, that's what I thought until a mysterious monster attacks the pâtissier! We also find out that Paris is hiding the realest sweet ever!? What is going on~~~!?
