Everyone at Ryokushou is participating in the Miyama school district's sports festival. Itsuka feels shy and awkward around Nagomu, causing her to adopt a brusque manner toward him. But in his loud cheers of encouragement she feels the warmth of family. Nagomu's father, Heigo, gets overly fired up and ends up hurting himself. Nagomu and Itsuka have to step up to take his and Nagomu's place in the parent-child event. Meanwhile, at Ryokushou, a woman calling herself Itsuka's mother appears.

A new artisan, Kisaichi Hiiro, arrives at Ryokushou. Enchanted by artisan Tatsumi Masa's sculpted sweets, Hiiro decides to become a wagashi artisan herself. However, her overly serious mindset and perfectionism cause her to lose sight of her surroundings and to make mistakes. She becomes despondent, then Masa teaches her about the spirit of an artisan. Amidst all of this, due to a whim of Nagomu's, Ryokushou holds a "Hands-on Wagashi Class" at the elementary school Itsuka attends.
