Ginga Eiyū Densetsu Die Neue These - All Seasons

For over a century and a half, two interstellar states have wrested for control of the Milky Way. The Galactic Empire, an absolute monarchy ruled by Kaiser Friedrich IV and an entrenched nobility, seeks to suppress the rebels daring to oppose the inviolable crown. The Free Planets Alliance, a representative democracy led by a corrupt High Council, degenerates as its elected leaders⁠ use war and conflict as a way to win popular support.

But this long-standing stalemate between the Empire and the Alliance ends with the rise of two opposing military geniuses. Reinhard von Lohengramm, a minor noble and High Admiral of the Empire through his strategic brilliance and his sister's position as the favored concubine of the Kaiser, dreams of conquering the galaxy and uniting mankind under his iron fist. Meanwhile, Yang Wen-li of the Alliance, an avid historian and reluctant commodore hailed as the Hero of El Facil, uses his tactical prowess to navigate around his leaders' incompetence—and to carve the path to lasting peace. As the war rages on, Reinhard and Yang each strive for their ideals and to secure their place among the stars as the leaders of a new era of galactic heroes.

The Free Planets Alliance's invasion of the Galactic Empire has failed after supply mismanagement led to heavy losses. Unwilling to abort the expedition despite being greatly outnumbered, Fleet Admiral Lazar Lobos orders the remaining Alliance fleets to gather in the Amritsar Starzone for a final stand against the incoming counterattack.

Strategic genius Fleet Admiral Reinhard von Lohengramm leads the Imperial forces into this decisive battle with an overwhelming advantage. However, his rival, tactical magician Vice Admiral Yang Wen-li of the Alliance, once again makes up for the incompetence of his superiors and stages a narrow escape for himself and his fellow soldiers. Though both Reinhard and Yang are displeased with the outcome—the former for his imperfect victory and the latter for the tremendous casualties—their attention must turn to the bubbling political unrest on both sides of the galaxy.

As Yang is ordered to appear before the Free Planet Alliance, he's shaken by the corruption he discovers. Meanwhile, Marshal Reinhardt uncovers disloyalty under his command as an upstart admiral launches a vicious offensive to retake the Iserlohn Fortress. Struggling to make strides in this never-ending bloody war, these two finally see their true enemy lies not from without—but from within!

After Yang Wen-li successfully captures the Iserlohn Fortress, the Free Planets Alliance grows bolder in its militaristic ambitions. With recent incursions into Galactic Empire territory and the possession of a perfect beachhead, the Alliance is now able to deal significant damage to the Empire. However, Reinhard von Lohengramm has no intention of allowing the Free Planets Alliance to gain a foothold. He is adamant about carrying on his best friend Siegfried Kircheis' dearest wish: to be the one to unite the universe.

As wide-scale military clashes continue, the opportunist Adrian Rubinsky, Fezzan's ambitious leader, attempts to take advantage of the war to further his personal goals.
