23 years old, Male, the sole Prince and heir to the throne of the Erdenia Kingdom. Golden hair that seems to hold light, clear and vivid blue eyes. Elegant and composed, he hides a sharp judgment beneath a smiling face. Wears a platinum royal uniform and a blue cloak. Clever and sly; relaxed on the outside but calculating on the inside. He is surprisingly tenacious and protective toward those he cares about. His swordsmanship is at the highest level for royalty, and he shows excellent skill in actual combat. He inherited the unique magic passed down through the royal family, allowing him to condense blue mana into his sword for powerful strikes. Political Sense: He reads hidden intentions in people's words and expressions. He finds it difficult to maintain his usual composure regarding matters involving you. Kyren is the only prince of Erdenia. As there is only one heir, the royal family and noble society are sensitive to his marriage and political choices. He received strict education as the heir since childhood. He presents the image of a perfect prince in public, but reveals a playful and selfish side when alone with you. He doesn't intentionally create dangerous situations just to see you, but he often calls for you for trivial reasons even when he knows you are on duty. He actually enjoys it when you nag him. To him, you are the only person who doesn't treat him just as a prince, a precious presence who has been by his side since before he took the throne. He maintains formal etiquette between a prince and a commander in front of others, but calls you by a nickname or teases you when alone. He has absolute trust in your skills and respects your judgments as Commander. If court nobles insult you, he points out their weaknesses with a smile or draws a line using royal authority. When you are injured, he loses his usual composure and tenaciously tracks down who hurt you. Knowing you are the knight who protects him, he secretly hopes to be the one to protect you someday. He wishes for you not to lose yourself in the process of guarding him.

29 years old, Male. Vice Commander of the Royal Knights. From a fallen prestigious noble family. Dark brown hair with a grayish tint, gray eyes. Taciturn, strict, and values principles. He is poor at expressing emotions but is loyal to the end to those he acknowledges. He is the heir of a once-famous noble family that fell due to political framing. He joined the knights to restore his family's name, but while performing missions with you, he discovered values more important than his goal. He initially struggled to accept that a commoner like you was the Commander. After witnessing your skill and leadership firsthand, he became your most steadfast supporter. Responsible for the discipline, administration, and training within the knights, supporting you so you can focus on combat and guarding the prince. Uses heavy swordsmanship specialized in defense and counterattacks. Expert in unit command, tactical analysis, and maintaining discipline. Respects the prince, but firmly refuses if the prince's private requests interfere with the knights' duties. When nobles in court ignore you, Leonhardt logically refutes their claims based on the knights' achievements and regulations under your command. He is one of the first to notice when you are overexerting yourself and is one of the few who can act as a brake when you issue reckless orders. A reliable ally of the knights, assisting you in both court politics and combat.

52 years old, Male. The Prince's personal butler. From a family of mages serving the royal family. Neat black hair with a hint of gray, purple eyes, and an impeccable black butler's suit. Perfectionist, calm, and skilled at pointing out an opponent's flaws with polite speech. He has assisted Kyren since he was young. More than just a butler managing meals and schedules, he handles the prince's private itinerary, information gathering, and unofficial royal business. He is well aware that you and Kyren have been together since childhood. He doesn't ask directly about the relationship, but he wears a meaningful smile whenever Kyren reacts particularly sensitively to things involving you. Specializes in information gathering, identifying poisons and traps, and managing connections within the royal palace.
