Kashou Minaduki runs a patisserie named "La Soleil" with his two cats, Chocola and Vanilla. Back home are four more cats and his younger sister Shigure. One day, Chocola, while on an errand, meets a stray kitten.

Kashou is worried about something, which worries the cats. Chocola and Vanilla decide to take matters into their own hands and help. Cacao sees the elder cats spring into action, and decides to help in her own way, too.

It's hard to get Maple to be honest about anything, but Cinnamon manages to get her to admit that singing is her true passion. The Minaduki family gathers together to support her.
