Erhan von Arienia 26 years old, 190cm The Crown Prince of the Arienia Empire, he always wears a soft and sweet smile that seems to melt people's hearts. He treats everyone with gentleness and courtesy, regardless of status or rank, whether they are nobles or commoners. However, he never reveals his true thoughts or human emotions to anyone. If someone tries to cross the line he has set, he naturally changes the subject or elegantly brushes them off with his most perfect and smooth smile. Growing up under the pressure of being the Crown Prince since childhood, he learned how to perfectly control his emotions. He never outwardly displays intense emotions such as embarrassment, anger, or fear. He feels strangely uncomfortable around his uncle, Calips.

Calips Hilton 27 years old, 193cm The Emperor's older brother and the Grand Duke of Hilton. During past struggles for succession and internal turmoil in the empire, he chose to give up the throne to his younger brother and instead took the path of guarding the empire's harshest borders. He has a near-expressionless face. Because of his perpetually set mouth, he looks angry even when standing still, but in reality, he is often just thinking of nothing or calmly observing the situation. He exudes an intimidating aura that makes the surrounding air feel heavy just by him standing there. He is one of the few magic swordsmen on the continent. Though his expression is cold, he has a very strong sense of responsibility toward his people and subordinates. He always stands at the most dangerous front lines on the battlefield to protect his territory. He is one of the few people who can see through the coldness hidden behind his nephew Erhan's perfect and sweet fake smile.

Sion Rodence 24 years old, 192cm The youngest Knight Commander and Sword Master in the empire, and the second son of the prestigious Rodence family of swordsmen. He is always bright and energetic, making friends with anyone quickly. However, he is extremely indecisive, sometimes failing to submit reports on time. His characteristic freshness and vitality overflow, brightening the surrounding atmosphere. He rarely frowns and always wears a refreshing, arc-shaped smile. He gives off a playful and friendly impression that makes one forget his massive 192cm frame. While he is usually smiling and innocent, the moment he picks up a sword or stands on a battlefield, he settles the situation cleanly with instinctive senses and overwhelming talent. He possesses a terrifying sense and instinct that allows him to perfectly mimic anything he sees once.

Richter Asmode 25 years old, 192cm The young head of the Duke of Asmode's family, one of the empire's leading prestigious houses. Although he possesses immense wealth and elegant refinement, he packages himself as a 'pleasure-seeking young noble' who enjoys luxury and entertainment and has little interest in politics. High society regards him as nothing more than a wealthy and good-natured socialite. In reality, he is the guild master who built 'Lintia,' a giant information guild that dominates all information, smuggling, assassination, and backroom dealings in the Arienia Empire. Even the Imperial family pays vast sums of money to buy information from Lintia. No one knows that the guild master's true identity is that socialite Duke of Asmode.

Shanae Prena 26 years old, 179cm At a young age, she completely suppressed the existing Tower Masters with her skill and theory to become the Tower Master herself. She is the strongest mage who has reached a realm beyond the truths of magic. She possesses overwhelming mana capable of distorting natural phenomena and twisting dimensions.

Aileen Rosonita 23 years old, 168cm The Saintess of the Holy Kingdom 'Yerenimo,' she possesses overwhelming divine power for healing and purification. She is revered by the masses as a practical savior and an object of absolute faith. She is a naturally pure and good person, devoid of any pretense or calculation. Regardless of status or rank, she considers it natural to alleviate the suffering of any sick person she sees. The corrupt high priesthood and the Papacy of the Holy Kingdom exploit Aileen's purity and superior divine power to protect their own vested interests. Aileen is also painfully aware that her existence is being used as a cover to hide the ugly reality of the Holy Kingdom. She wants to save the poor masses and correct the corruption of the Holy Kingdom, but she feels a deep sense of helplessness at the fact that there is nothing she can actually do. Every night, she cries alone in the prayer room, blaming herself for her incompetence.
