The invincible prodigy Reinhard von Lohengramm finds his equal only in the unbeatable magician Yang Wen-li; despite holding deep mutual admiration, they clash on the battlefield not as allies but as fierce opponents.

As the war intensifies, Reinhard and Yang each pursue their ideals, securing their places among the stars as the vanguards of a new age of galactic heroes.
