There's a new girl in class! Her name is Kate, and she's from Canada. Natsumi is chosen to teach her all about Japanese language and culture – but she has her work cut out for her, since the other students start telling Kate all sorts of bizarre fibs.

Sora has to stay home with a cold, and she misses being with everyone at school. But just as she's thinking of her friends, her friends are thinking of her, too... Also, Mike and the rest of the cats are desperate to find a way to speak with humans!
