In the distant future, humanity is under attack by the Abh Empire, a race of advanced humanoid beings possessing vastly superior technology. As countless worlds fall to the Abh, mankind establishes the Four Nations Alliance—a resistance faction made up of the United Mankind, the Republic of Greater Alcont, the Federation of Hania, and the People's Sovereign of Union Planets. Seikai no Monshou tells the story of Jinto Linn. When he was young, his father—the president of Martine—sold their world in exchange for a high position in the empire. Now a young count, Jinto must learn the ways of Abh nobility and live among those who subjugated his people. Helping him is Lafiel Abriel, an austere Abh princess whom Jinto quickly befriends. While traveling to Jinto's new school in the Abh homeland, their ship is caught in a violent space battle between the fleets of the Alliance and the Abh. Jinto and Abriel are thrust into the conflict, unaware that this skirmish marks the beginning of a full-scale war between the Abh Empire and mankind. [Written by MAL Rewrite]
