In the thirty-sixth century, humanity has conquered the galaxy and colonized countless star systems. The Galactic Empire, modeled along Prussian lines, and the democratic Free Planets Alliance are at war, and the fate of every human being in the universe hangs in the balance. This classic Japanese space opera, adapted into a legendary anime, is finally available in English for the first time.

A grand scheme for retaking Iserlohn is delivered to Reinhard, who with renewed determination seeks to become ruler of the galaxy, and fulfill the oath he made with a dear, departed friend. But what are the aims of Phezzan, the third force at work behind the scenes?
Meanwhile, no sooner is Yang breathing a sigh of relief when Julian returns from his first combat mission than he is summoned to an inquest and departs for the capital of the Alliance. As if waiting for this opportunity to strike, however, the Imperial military's fortress appears right at the gates of Iserlohn. The battle between two gigantic fortresses begins!
