Having a friend that knows you inside out should be a good thing, but in Nishikata's case, the opposite is true. His classmate Takagi loves to tease him on a daily basis, and she uses her extensive knowledge of his behavior to predict exactly how he will react to her teasing, making it nearly impossible for Nishikata to ever make a successful comeback. Despite this, Nishikata vows to someday give Takagi a taste of her own medicine by making her blush out of embarrassment from his teasing.

Cheerful teenager Ichika Usami has a passion for sweets that is inspired by her mother's baking. In celebration of her mother's return from overseas, she tries her hand at making a cake herself. She is interrupted when a dog-like fairy named Pekorin crashes into her kitchen. With Pekorin's help, Ichika successfully bakes her cake. Only then enters an imp named Gummy who bursts in and attempt to steal the cake's kirakiraru, a magical power that gives sweets the ability to bring happiness. Though Ichika initially offers her cake to Gummy in order to protect Pekorin, the fairy helps her realize how important the treat is and the love it represents. As the kirakiraru within Ichika's cake grows, it changes into a set of trinkets that transforms her into Cure Whip, a hero known as a Pretty Cure. Using her newfound powers, she goes on to battle kirakiraru thieves whenever they appear. Ichika fights to protect Ichigozaka's sweets and finds colorful new allies along the way.

Ryoutsu, being an underpaid policeman, is always coming up with underhanded schemes in order to make a quick buck. But in the end, his plans (which are ridiculous to begin with) always go wrong and land him in big trouble with the chief.

Long ago, there was a monk named Myoue who could bring anything he drew to life. He quietly lived with his wife Koto—a black rabbit in human form—and their three children: Yakushimaru, Kurama, and Yase. One day, the high priest of the land concluded that Myoue's drawings caused too many problems for the locals and ordered him to find a solution. In response, the family secretly fled to an alternate world of Myoue's own creation—the Looking Glass City. Everything was peaceful until Myoue and Koto suddenly vanished. Their three children are left to take care of the city, and Yakushimaru inherits Myoue's name and duties. Stranded in this alternate world, their problems only get worse when a young girl—also named Koto—crashes down from the sky and declares that she is also looking for the older Myoue and Koto. Armed with a giant hammer and two rowdy familiars, Koto just might be the key to releasing everyone from the eternal paper city.
