Kashou and Shigure Minazuki are accompanied by a group of six catgirls, among them Chocola and Vanilla who assist Kashou at the patisserie La Soleil. Meanwhile, Coconut, Azuki, Cinnamon, and Maple keep Shigure company at home. One day, when Chocola is running an errand, she stumbles upon a green-haired kitten all by herself in the park. Concerned, she brings the kitten back to the patisserie where the Minazuki clan decides to adopt her and give her the name Cacao. As a new member of the household, Cacao adds excitement to their daily routines.
