In the far future, two young military leaders rise above their peers. The invincible genius Reinhard von Lohengramm is matched only by the unbeatable magician Yang Wen-li; though the two share a profound respect for each other, they meet on the battlefield not as comrades but as bitter adversaries. Commanding thousands of warships and millions of soldiers, they lead giant space fleets into battle on behalf of the two interstellar states that have wrested for control of the Milky Way for over a century and a half. 

The Galactic Empire, an absolute monarchy ruled by Kaiser Friedrich von Goldenbaum 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. Reinhard is a minor noble who became a High Admiral through his strategic brilliance and his sister's position as the favored concubine of the Kaiser, while Yang is an avid historian and reluctant commodore hailed as a hero despite only using his tactical prowess to navigate around his leaders' incompetence. On opposite sides of the galaxy, the two men have wildly different visions for the future: Reinhard dreams of uniting mankind under his iron fist, while Yang wants only to carve a path to lasting peace. As the war rages on, Reinhard and Yang each strive for their ideals and secure their place among the stars as the leaders of a new era of galactic heroes.

Legend of the Galactic Heroes

銀河英雄伝説

Tezuka, Osamu

From time immemorial to the age of space colonization, there is one legend that has stayed unchanged in every history book—the tale of the immortal bird Phoenix. A being whose blood is said to grant eternal life or wisdom, the radiant figure ensures the continuation of sentient life in the universe as it oversees human civilizations and their development.

Yet, mankind remains a slave to its habits; from happiness and sorrow, to wrath and love, a myriad of emotions continue to play an integral part of human life. Simultaneously, time and time again, certain beliefs and agendas persist over the centuries to disturb the fragile equilibrium of the world's preordained nature and principles. It appears that fate, with its dynamic variables, can manifest itself in many ways—and oftentimes exhibits a bizarre sense of humor.
