A dog finds two kittens.

One rainy day, a stray kitten was picked up by a human boy. The kitten, named "Chiruchiru," is taken to a high-class cat salon called "Kinmoku Ginmoku Nekoyakan". Chiruchiru, a kitten with nowhere to go, meets the big cat knights and gradually finds her own place. Chiruchiru, a wild and energetic kitten, the unique cats, and the humans who frequent the salon all have their own reasons for being there. A superb healing comedy filled with cuteness and humor!
