・The eldest child and First Prince. ・The most likely candidate for the next Emperor. As Co-Emperor, he assists his father. ・Since the Emperor is often away on foreign campaigns, he has been entrusted with politics as the acting Emperor during those times. ・He has a good personality and connections with almost every faction. His influence is such that if he mediates a conflict between factions, both sides will reach a compromise. The same applies to diplomacy. ・He has no clear enemies. ・He gets along well with his siblings and is generally relied upon. ・Trust in him is so strong that everyone would be satisfied if he became the next Emperor. ・While he is head and shoulders above the rest in networking and diplomacy, he is mediocre in other fields. Therefore, he intends to delegate those tasks to people who specialize in them, and his ability to do so is his strength. ・On the other hand, he lacks a desire for power and dislikes the struggle for the throne.

・The Second Prince and Grand Vizier. The Emperor's second child. ・Extremely brilliant and virtually flawless in all fields. ・The most trusted individual among the empire's bureaucrats. ・He is cold-blooded and can only perceive things rationally. However, he is capable of behaving in a way that does not let others realize this. ・He generally behaves in an approachable manner, so he doesn't give a cold impression. However, he hides a mechanical, rational way of thinking inside. ・Though he seems kind, he possesses a cold-bloodedness that allows him to choose any means to achieve his goals. ・A master strategist; no one surpasses him in political maneuvering or tactics. ・He is the intellectual type who moves the world from the shadows using high intelligence and political power rather than going to the front lines. ・His talent lies in his grand strategic and conspiratorial abilities, viewing the battlefield like a chessboard and constructing victory on a global scale. ・He does not view the throne as absolute; as long as the empire's prosperity is achieved, that is enough. He would gladly offer himself as a gear for the sake of the empire.

・The First Princess. The Emperor's third child. ・A military officer known by the epithet "Angel of the Battlefield." As one of the Imperial Generals, she has dedicated herself to expanding the territory. ・She has deep support from the soldiers on the front lines. ・While Leon has the talent of a Commander-in-Chief, she excels as a field commander. ・She values rule by force and pride, but she has a compassionate side that deeply cherishes those close to her. ・Her talent lies in her overwhelming tactical and combat abilities, leading troops on the ground to bring victory. She possesses the martial might to lead the charge and personally shatter enemy formations. Furthermore, because she is always on the front lines, she has the charisma to raise military morale to its peak.

・The Second Princess. The youngest child of the Emperor. ・She lacks strategic wit or martial prowess but is kinder than anyone else. With pure ideals free of calculation or lies, she attracts people's hearts and turns them into allies regardless of whether they are friend or foe. ・She boasts immense popularity among the citizens of the capital. ・She has the talent of an "absolute charisma" that moves the world through sincere purity. ・Once she decides on something, she has the judgment and decisiveness to carry it out even over the objections of those around her. ・While Leon moves people through calculation, she moves people through sincerity. Even Leon highly evaluates and fears this talent of hers. ・While Eudokia provides order through fear and force, she seeks to eliminate conflict through kindness.

・The current Emperor of Vasilia. He built the empire's golden age with his rare talents. ・He primarily ruled through a reign of terror and frequent foreign campaigns, expanding the empire's territory to its greatest extent in history. ・He also commissioned the compilation of a legal code to solidify his own power. ・He intends to have his children compete for the throne and make the most capable one his successor.
