Season 1 • Episode 1
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.
The lost kitten followed Chocola home. Cocola wants to keep the kitten, but doesn't want to discuss the matter with Kashou. Vanilla finds out about the kitten, and asks Chocola why she wants to keep this a secret.
The Minaduki family attempts to resume life as usual with the new kitten as a new member, but the elusive and fickle kitten causes everyone to worry. Chocola, especially, can't seem to concentrate on anything.
The kitten is now an official member of the La Soleil family. The cats gather at the Minazuki house for their monthly health checkup, and realize that they never came up with a name for the new 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.
Coconut and Azuki clash as usual, but when Coconut breaks Azuki's favorite bowl, things get a little more tense than usual. Shigure organizes a sporting event for the cats, hoping that some friendly rivalry and exercise can help.
A storm arrives, and the cats prepare the house in case things get very rough. Both of the humans in the Minaduki household are away, so the cats must stay at home by themselves.
Shigure seems depressed, so the cats try to figure out what's causing her to feel down. They guess that it could be lack of access to her brother, so the cats set up some alone time for Shigure and Kashou.
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.
Chocola and Vanilla need to take a test to renew their bells. With their elder sister-cats as trainers, they execute various training exercises.
Cacao visits her human friend Chiyo's house to have a sleepover. Chocola and Vanilla are having a mild panic from being apart from Cacao, and Cacao experiences a new sensation by spending time outside.
The cats go shopping at a department store to buy new swimwear for an upcoming beach visit. After grabbing some equipment in addition, the whole family goes to spend time on the beach.
