The action of this human drama takes place in the city of Echizen. The main character, whose grandfather was a master of washi (making Japanese traditional paper), gets acquainted with the culture and history of Echizen-washi and realizes her responsibility as a successor. Natsu Iwasaki was born in the city of Echizen and grew up familiar with washi as a descendant of washi artisans. When she was a child, she drew pictures on washi made by her grandfather, and received an award from the governor of the prefecture. However, I did not receive any prizes at the art university in the specialty “watercolor painting”, and now I am not sure of myself. Natsu and her family live in Tokyo, and her 80-year-old grandfather Junji still makes handmade Japanese paper in the city of Echizen alone.
