The story of Kozukuri Ninkatsu Bu! centers on Ao Suto (洲藤蒼), a self-confessed, passionate otaku who often discusses his hobbies with his classmates. Despite his enthusiasm, Ao has never had a girlfriend and is openly mocked by his classmate, Umi Tono, who dismissively calls him "Otaku-kun". However, beneath his shy exterior, Ao harbors a dream: to find a good partner and start a family.
The study of human activities (ninkatsu) within this context reveals the intricate relationship between communities and their environments. It highlights the skills passed down through generations, the challenges faced by modernizing agriculture, and the cultural significance of chestnuts. From an agricultural science perspective, understanding these dynamics can provide insights into sustainable practices and community development.
