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.
No matter the person, 
everyone makes mistakes.
كائناً من كان، الجميع خطّاؤون
Alle Menschen machen Fehler.
Todo el mundo comete errores.
Todo el mundo comete errores.
Tout le monde fait des erreurs.
Tutti commettono errori.
Todo mundo comete erros,
não importe quem for.
Любой человек может ошибиться.
