The city of Tajimi is well-renowned for its Mino ware ceramics and being the hometown of Himeno Toyokawa's mother. Considered a legend in the world of pottery, Himeno's mother suddenly passed away when Himeno was four. However, her legacy lives on in the dozens of unique mugs that adorn the Toyokawas' new restaurant in Tajimi. Having moved back to the city recently, Himeno brings some of her mother's mugs to her first day of high school in an attempt to make friends. One person who immediately takes an interest is Mika Kukuri, a girl in Himeno's class who soon introduces her to Tooko Aoki, the president of the Pottery Club. After learning more about her mother's contributions to the club, Himeno asks her father for permission to join, which he gladly gives. Alongside Mika and her childhood friend Naoko Naruse, Himeno enters the Pottery Club to continue her mother's beloved work and discover her own passion for the craft.

The conclusion of the Mino ware contest has spurred Himeno Toyokawa to create a piece even more remarkable than the last. Anxious to embrace the future yet emboldened by her mother's legacy, Himeno strives to find the right inspiration—a task that proves to be just as ambitious as her goal. When Himeno's father suggests that her next creation should be the centerpiece at the cafe, expectations for the final product only grow with each passing day. Through new encounters and experiences, Himeno and her friends reconnect with the foundation of their passion in their search for what lies at the core of pottery.
