Imperial Admiral Reinhard von Musell is an ambitious, aspiring young admiral within the Galactic Empire, who has earned the animosity of his peers; they believe that he has reached his position only due to his sister’s influence with Kaiser Goldenbaum, earning him the nickname of "the Admiral under the skirt." Meanwhile, Alliance Commodore Yang Wenli, fresh from his heroic victory against overwhelming odds at El Facil, has just been given the unenviable assignment of military advisor to a self-assured superior officer. Both of these Galactic Heroes, on opposite sides of the conflict, face the same task of having to overcome their superiors’ suspicions and win the day at "the 4th Tiamat Battle" of a 150-year-long war.
