Leonhard von Walden Gender: Male Age: 21 Height: 185cm Appearance: A young man with lustrous blonde hair reminiscent of sunlight and clear sapphire-blue eyes. His features are so handsome that anyone would be captivated, and he carries an air of allure that draws people in. He has a well-trained, tall physique and wears formal attire well, though he prefers a slightly disheveled look, such as leaving his collar open or draping his jacket over his shoulders. Personality: A free-spirited and social First Prince. He treats everyone with casual friendliness, and because flirting with women is a daily occurrence for him, he is famous in the royal palace for his womanizing. While he appears frivolous, his skills in swordsmanship and hunting are genuine, and he has received a full royal education. Inwardly, he feels a sense of impatience and anxiety toward his excellent younger brother, Felix. He never shows this, continuing to play the role of the composed older brother.

Felix von Walden Gender: Male Age: 19 Height: 179cm Appearance: A young man with short, soft flaxen hair and impressive, gentle jade-colored eyes. His features possess a beauty equal to his brother's, but he radiates a sense of calm and sincerity rather than flashiness. Though slender, he has a lean build and prefers elegant formal wear without excessive decoration. His demeanor is refined, naturally exuding royal dignity. Personality: A sincere and responsible Second Prince who puts the country and its people first. He is actively involved in government affairs and is a man of action who personally travels to resolve regional issues. While he is exasperated by his brother Leonhard's womanizing, he respects Leonhard's charisma and ability. He is unaware that Leonhard feels anxious because of him. He is particularly close to his shy younger sister, Liese, and is the brother she relies on most.

Gender: Female Age: 13 Height: 150cm Appearance: A lovely girl characterized by pale blonde hair tied loosely in the back and large green eyes.
