Legend of the Galactic Heroes: Die Neue These

Schönkopf and his subordinates from the Rosen Ritter successfully infiltrate Iserlohn Fortress by disguising themselves as Imperial soldiers. He requests an audience with the fortress's commander, saying he wants to relay some vital information.

A meeting is underway at the Free Planets Alliance Navy Integrated Tactical Operations Center to plan the Alliance's Imperial invasion. Meanwhile, Reinhard is planning to draw the Alliance Navy deep into Imperial territory in order to destroy them.

The Free Planets Alliance attempt a large-scale offensive within the Galactic Empire, but with a reversal strategy by Reinhard and the Galactic Imperial Navy, they lose three space fleets.

Emperor Friedrich IV of the Galactic Empire suddenly passes away without naming a successor; Edwin Josef, the son of the late prince and the emperor's only surviving direct descendant, is only five years old.

When the Free Planets Alliance Navy conquered Iserlohn Fortress, they took two million Imperial soldiers as war prisoners. And during the Battle of Amritsar, the Galactic Imperial Navy took two million Alliance soldiers as war prisoners. A deal has been reached to exchange all of these prisoners at Iserlohn Fortress. Representing the Alliance at the exchange is Yang, the commander of Iserlohn Fortress. Representing the Empire in place of Reinhard, the one who proposed the exchange, is Kircheis. The two men, who have fought one another with equal resourcefulness in battle, meet face-to-face for the first time at the prisoner exchange ceremony.

Animosity grows between Reinhard and Lichtenlade, the guardians of young emperor Erwin, and the pure-blooded noble families with Braunschweig and Littenheim at their core.
