When his father was compelled to sell Annerose for money as a concubine of Emperor Friedrich IV, young Reinhard swears to put an end to the Goldenbaum Dynasty.
At the age of 15, Reinhard and Kircheis enter their first active service in the army; their rapid promotion in rank follows, owing it to their outstanding contributions to the country.
With brilliancy in military strategy especially at a macro-level, and giftedness in civil affairs and in identifying ones with talent, Reinhard succeeds in attracting a great number of able officers, gaining as well the admiration of the public.
In solidifying his grounds by gathering advocates, Reinhard does not miss an opportunity to take advantage of his handsomeness and other charming qualities.
Believing that the Universe should be reigned over by the most powerful and capable person, Reinhard leaves a will to his Empress consort Hildegard, in which he states that if their son (Alexander Siegfried) fails to prove promising as his successor, there should be no reason for the Lohengramm Dynasty to continue.
Though a matchless genius by all account, Reinhard's main flaw lies in the restriction of his emotions, as he opens his heart to two people only: his beloved sister Annerose and his closest friend and loyal companion Kircheis.
Annerose describes him as a star that shines brightly until it completely burns itself out; that the day Reinhard slows down his pace would be the dawn of his end.
Built with the latest technology of the time, the battleship earns a sobriquet ‘The Unsinkable Ship', for surviving all of her battles without a single damage in spite of its constant acting as a spearhead of the fleet.
The only damage Brünhild ever receives is caused by an infiltration from which a direct engagement of battle ensues with a boarding party of 730 combatants led by Julian Mintz towards the end of the series.
Not willing to take on a bigger role or responsibility, he and Reinhard's battle were never in equal footing and at same time handcuffing him from doing things that could change the scale of the power balance.
He also agrees that benevolent autocracy is better and more efficient than corrupted democracy if social change is needed, and noted that if he was born in the empire, he would actually volunteer to serve under Reinhard despite his dislike of military.
She served as the New Galactic Fleet's Chief Advisor, and later reigned with Reinhard von Lohengramm when she became his wife and Empress in 801 UC.
Hildegard, usually referred to by the nickname Hilda, was born in 777 UC into a distinguished noble family of the Goldenbaum Dynasty, the sole daughter of the benevolent and just Count Franz von Mariendorf.
In 797 UC, the old Galactic Empire split into civil war, where the old nobility stood against the new emerging camp of military elites led by Reinhard von Lohengramm.
During Operation Ragnarök, where the empire battled the Alliance, Hilda served as a staff officer on board the flagship Brünhild.
In the year UC 800, in the Ninth Battle of Iserlohn, Hilda succeeded Admiral Steinmetz to become the Fleet's Chief Advisor, formally capable of representing the Emperor and command on his behalf on the battlefield.
Subconsciously realizing that his reliance on her has deepened past their professional relationship, he asked her to stay, and she agreed, determined to help him to the best of her abilities.
She also did not reveal her pregnancy to him until after the Urvashi affair and Reuenthal's subsequent rebellion, which deepened the insight of both Hilda and Reinhard toward their own feelings.
Reinhard's illness seriously exacerbated a mere sixteen days later and was diagnosed with a rare form mutative connective tissue disease, with no known cure.
During the first season, Lady Annerose told Kircheis that should Lord Reinhard one day stop listening to him, then he will walk down the path of self-destruction.
Julian Mintz, voiced by Nozomu Sasaki is the adopted teenage son of Yang Wen Li.
Oskar von Reuenthal, voiced by Norio Wakamoto, flagship Tristan, is someone with vast intelligence and talent.
He has no problems finding women, but he despises the idea of settling down and having children because his mother attempted to kill him when he was an infant due to his heterochromatic eyes.
In the end his pride compelled him to rebel after being framed for an assassination attempt against Reinhard and died of wounds taken during a battle against Mittermeyer, but in his heart he was still supportive and loyal to him.
Wolfgang Mittermeyer, voiced by Katsuji Mori, flagship Beowulf, is best friends with Reuenthal and both were together referred to as the "Twin Pillars of the Empire", after the death of Kircheis.
Paul von Oberstein, voiced by Kaneto Shiozawa, first served as Reinhard's advisor and later as Minister of Military Affairs.
Kesler was usually sent to serve in rural areas or in similar unpopular assignments as indirect punishment for his integrity under the corrupt old rule.
While preventing an assassination attempt against Kaiserine Hildegard and Crown Princess Annerose by the Terraist cult, he meets Marika von Freuerbach, a servant, whom he marries two years later.
In that maneuver, his fleet caused significant damage to the Flagship Hyperion, killing High Admiral Merkatz.
The Terraist Church is a secret society which emphasized that humans should all return to their home planet of Earth and re-establish its fame as the capital of the universe.
