Nagi no Asukara is the story of two subsects of humanity: land-dwellers and sea-dwellers. As the culture of humanity on land grows, the more separate the culture of the sea becomes. Catastrophe draws ever closer as the population of the once-vibrant sea community dwindles, and the near-forgotten sea god preparing to freeze the land, tipping the balance of power back to the sea in the distant future. Faced with this calamity, four junior high school students, the last of the sea population’s youth, are caught in the friction between land and sea.
Four friends from a village beneath the ocean become unwitting ambassadors to a village on land when their own school closes down due to a lack of students. Tensions run high between the children from both the land and sea; however, as Nagi no Asukara progresses, individuals begin to form strong relationships, romantic or otherwise. These bonds lead to additional tension and understanding as the adolescents struggle to express or hide their respective emotions while a calamity looms in the horizon.
The two paragraphs above are plot synopses for the same series: Nagi no Asukara. One focuses on the social and political narrative within the series, while the other focuses specifically on the character relationships. Chances are, if you are a viewer of the series, your emotional investment is firmly entrenched in the latter, rather than the former. It’s difficult to care about the overarching narrative of the world slowly going into a deep freeze when all you want is for Miuna Shiodome to find her happiness. It is a credit to the writing of Nagi no Asukara, headed by series composer Mari Okada, that it integrates both stories so well.
