After seeing his son's immaturity, his father⁠—also a master calligrapher—sends Handa to a village in the Goto Islands as punishment. Deprived of city comforts, Handa moves into a house in the local village with the sole intention of spending his stay engrossed in calligraphy. However, the house he has moved into was previously the hideout for some rambunctious children, headed by Naru Kotoishi, who are unwilling to move out. Furthermore, the neighbors seem very interested in the calligrapher, who they see as an amusing oddity!

Despite Handa having been uprooted from his comfortable lifestyle, his experiences with the village and its people will teach him things about himself, life, and calligraphy.
