The story follows the adventures of two young people, Lafiel and Jinto (along with the Abh ship Goslauth, aka Gosroth) find themselves at the very beginnings of a war between the Abh Empire and the Four Nations Alliance of humankind—an anti-Abh alliance of the democratic nations of the United Mankind, the Federation of Hania, the Republic of Greater Alcont, and the People's Sovereign Union of Planets.
