Shikada Dagashi, a small company providing traditional Japanese confectionery, is located in the countryside and has been managed by the Shikada family for nine generations. Despite his father's efforts, however, Kokonotsu Shikada, an aspiring manga artist, refuses to inherit the family company. However, with the entrance of the eccentric Hotaru Shidare, this may begin to change. Hotaru is looking for Kokonotsu's father in order to get him to return to her family's firm, Shidare Corporation, a world-renowned sweets producer. Although the older Shikada first declines, he claims that he would reconsider if Hotaru can persuade Kokonotsu to take over the family business. So Hotaru's endeavor to teach the youngster on the actual joy starts.
