Atragon is set in the 1960s, during the postwar era. This time period was marked by rapid technological progress and geopolitical tension, making the concept of a high-tech atomic submarine plausible as a guardian of peace. The historical context frames the moral choices around power and responsibility during a time when Japan was rebuilding while facing a renewed threat from the lost continent of Mu.

Atragon explores three interconnected themes. Power & Duty examines whether great power should serve collective safety or be used for imperial revival. War & Peace shows how Mu's threat forces international cooperation and the cost of choosing vengeance over compromise. Empire & Legacy probes whether national pride can justify monumental weapons and if legacy should guide or hinder the present.
