Legend of the Galactic Heroes: Die Neue These

A few thousand years in the future, humans have begun to immigrate into space. These space colonies where split into two countries with opposing government organizations called the Galactic Empire--an autocracy--and the Free Galaxy Alliance--a democracy. These two nations fight together in the endless galaxy for over 150 years. The two nations continue to fight. The Galactic Empire is beginning to crumble due to its society of nobles. On the other hand, the abuse of the democratic system has turned the country's politics into a mobocracy. At the end of the eighth century in the space calendar, history begins to chance due to the appearance of two people: the invincible genius Reinhard von Lohengramm, and the never-losing magus Yang Wen-Li. With each controlling an opposing force, they find themselves clashing again and again.
