Shizuku is a cheerful rural girl, born and raised on a dairy farm. She has strong work ethics, a positive outlook on life, and an unlimited love for cows. With a catchphrase of "Moo♪", she carries the motif of her favorite animal, specifically the black and white heifers known as Holstein Friesian cattle. As the daughter of a farmer from the countryside of the Iwate Prefecture, she is not ignorant of technology and the times but still finds city life new and exciting.
