Number 1: Azu and Yuihopper
The first story is adapted from the "Grasshopper and Ant" story. Azusa plays the a hard-working ant who collects food before the winter, while Yui plays the role of the lazy grasshopper who relaxes all day. During the winter, the grasshopper starves, but the kind ant allows the grasshopper to enter and enjoy the food. The grasshopper fails to learn from her mistakes and last year's events repeat themselves next year.

Number 2: Yuisparrow
The second story is about the sparrow (played by Yui) and the cat named Azu-nyan (played by Azusa). The cat has to save the sparrow but brings trouble to its master. The sparrow continues eating Jun's cake which makes Azu-nyan guilty because of her previous actions.

Number 3: Azutaro
The final story is about Azutaro, who lives in Mt. Masakari and describes a journey to catch the devil. Soon, a dog, pheasant, and monkey appear, asking for dumplings. Azutaro gives only one dumpling to them and they leave after eating the dumpling, butchering the story.
