This movie, based on an anecdote of "Ginga Eiyuu Densetsu" written by novelist Tanaka Yoshiki, preludes the 110-episodes TV series by describing the first encounter between the ambitious young man Reinhard von Müsel under the imperial flag and the passive Yang Wenli who serves a corrupting democracy. Set in an imaginative future, the story describes the first encounter between Yang and Reinhard and discusses how heroes are born.

For decades, the Galactic Empire has been locked in an interstellar war with the Free Planets Alliance, a conflict that involves thousands of spaceships and millions of soldiers on both sides. Two new commanders enter the conflict with great hopes: Imperial Admiral Reinhard von Lohengramm and the FPA's Yang Wen-Li. As they deal with superiors and subordinates, maneuver through complicated political arrangements, plot strategies, and win battles, each will be tested, and ultimately, changed, by the reality of war.

Prequel to the original series, focusing on Reinhard and his steps up the chain of command in the Galactic Empire.

A prequel to The Legend of the Galactic Heroes, focusing on the FPA's Yang Wen-li. A chronicle on how he earned the title "The Hero of El Facile" and his handling of assignments he received after the historic event.

Spiral Labyrinth also continues with the background of Reinhard and Kircheis where the first Gaiden left off.

Thousands of years later, humanity has advanced into space. Here it has divided into two countries with two different forms of government: the autocracy of the Galactic Empire, and the democracy of the Free Planets Alliance. These two countries have been at war for 150 years, which turned the galaxy into a stage for a never-ending series of conflicts.

As the long war continues, both countries fall into decline. The Galactic Empire suffers corruption among the noble classes, while the Free Planets Alliance falls victim to the mob rule of democracy. Then, near the end of the 8th age of the space calendar, the appearance of two geniuses will change history forever. The unstoppable genius, Reinhard von Lohengramm, and the unbeatable magician, Yang Wen-li. As heads of the Imperial and Alliance armies respectively, the two will face each other in battle over and over again.

The year is UC 796 (Imperial Calendar year 487). The Free Planets Alliance expedition, thirty million soldiers strong, entered Imperial territory and engaged with Fleet Admiral Reinhard's massive fleet as well as the entire Galactic Empire Space Fleet, also led by Reinhard as its new vice commander. As a result, the Alliance lost three of its eight fleets. However, after learning the intentions of the Free Planets Alliance High Council, Commander-in-Chief Lobos gave the order for the surviving fleets to assemble and continue the battle. Reinhard, desiring a perfect victory, advanced on the Amritsar Starzone, where the remaining Alliance fleets were amassing. And so the curtain rose on the Battle of Amritsar.

The social and political reforms implemented by Reinhard are earning more and more support from the citizens of the Galactic Empire. Meanwhile, the Free Planets Alliance is experiencing a declining phase, its national power weakened significantly due to widespread government corruption, despite the military success it has achieved on the battlefield.

As the balance of power between the two superstates dominating the Galaxy is clearly undergoing a major shift, Adrian Rubinsky, the Landesherr of the autonomous and nominally neutral dominion of Fezzan, sees an opportunity to take advantage of the situation.
