In a cone-shaped land named Kikyōgahara in Shin Province, there lives a girl named Hana. She is a gentle girl, who always thinks of her family, in particular her great-grandmother Chiyo, whom she affectionately calls "Granny." One day, a traveling entertainment troupe named the Natsugawa Genzaemon Troupe happens by, and the villagers welcome them warmly.
