"A summer promise. A little bit of courage. And a whole lot of cats."
Summer vacation has arrived at the Minaduki household. While Shigure and the older catgirls are busy planning how to spend their time, the youngest "kitten," Cinnamon, finds herself facing an unexpected problem.
Usually the cool and composed one, Cinnamon is struggling to write a letter to her parents. It seems like a simple task, but for a kitten striving to become an adult, the words just won't come out. When the family decides to go on a trip to the beach, Cinnamon sees it as the perfect opportunity to find inspiration—but she ends up finding much more than she bargained for!
From splashing in the ocean to a heartwarming moment under the stars, this is a story about growing up, the bonds of family, and the summer memories that stay with you forever.
