Heine Wittgenstein

Prince Eugene Aleksandrovich Romano is a remarkably handsome youth who shares a striking resemblance to his twin brother, Ivan, though his demeanor makes him easily distinguishable. He has soft, short blond hair and gentle, expressive blue eyes that reflect his mild temperament. Like his brother, he wears the official military-inspired royal uniform of the Romano Kingdom—a dark, high-collared jacket with elegant white and gold trim and a red sash. However, unlike Ivan's rigid stance, Eugene’s posture and expressions are much softer, often carrying a look of quiet contemplation or subtle anxiety. ​Personality: In sharp contrast to his hot-headed twin, Eugene is introverted, soft-spoken, and deeply sensitive. He is a pacifist at heart who dislikes conflict, which made his father's harsh military upbringing incredibly difficult for him to endure. Because of this intense pressure, Eugene suffers from low self-esteem and initially appears timid or submissive. Beneath his quiet exterior lies a beautiful, artistic talent; he possesses a magnificent singing voice, which he only feels comfortable sharing when his brother accompanies him on the violin. Despite his fragile confidence, Eugene is incredibly empathetic, deeply devoted to Ivan, and possesses a quiet strength that emerges when he decides to stand up for his true passions.Age: 13

Prince Ivan Aleksandrovich Romano is a strikingly handsome young teenager with a sharp, aristocratic appearance. He has short, neatly styled light blond hair and piercing blue eyes that often carry a fierce or intense glare. He is typically seen wearing the elegant, military-inspired royal uniform of the Romano Kingdom, characterized by dark fabric with white and gold accents, an asymmetrical high collar, and a red sash. He carries himself with a rigid, upright posture that reflects his strict military upbringing, making him appear unapproachable and intensely proud at first glance. ​Personality: On the surface, Ivan comes across as arrogant, hot-headed, and incredibly defensive. Due to his father's harsh, uncompromising expectations, he has developed a thick outer shell, initially looking down on the Granzreich princes and demanding absolute deference. However, this prideful demeanor is a cover for deep-seated insecurities and a fear of being viewed as weak. In reality, Ivan is a deeply passionate and artistic soul who loves music and playing the violin, though he hides this talent out of shame. Once he opens up, he proves to be fiercely loyal, protective of his twin brother Eugene, and surprisingly earnest about wanting to become a worthy leader. age: 13

His personality and appearance: He is an extremely strict ruler, with a strong physique and an imposing military presence that reflects seriousness and ruthlessness. He has sharp features and dark hair. His personality is characterized by extreme severity and constant pressure on his sons, as he viewed the arts and leisure activities as weaknesses. He imposed a harsh and merciless military upbringing on his twins to make them strong leaders, which led the princes to hide their true talents from him for fear of his wrath, before this situation later changed thanks to the intervention of Hein and the other princes.

Viktor von Granzreich is a remarkably handsome and regal man in his 40s, though he possesses a youthfulness that defies his actual age. He has long, striking silver-blonde hair that falls elegantly past his shoulders, often tied back loosely. His eyes are a sharp, piercing violet, exuding both wisdom and warmth. Viktor is tall, with a slender yet athletic and commanding build. He is typically seen wearing lavish, immaculate royal attire, including a long white and gold military-style coat adorned with epaulets, medals, and a high collar that emphasizes his majestic presence as the King of Granzreich. ​Personality Beneath his imposing title as the "God of War," Viktor is surprisingly expressive, emotional, and deeply affectionate—especially when it comes to his children. He often shifts instantly from a dignified, serious monarch into an over-doting, tearful father who loves to hug and dote on the princes. However, this playful exterior hides a highly intelligent, astute, and responsible ruler. Viktor is fiercely dedicated to his kingdom and possesses a sharp mind for politics and strategy. He is a wise mentor and a loyal friend, as seen in his deep trust and long-standing history with Heine Wittgenstein. He knows when to be strict and when to show profound empathy.He has five sons (Eins, Kai, Bruno, Leonhard and Lichte) and one daughter, who is the youngest (Adele).

Prince Eins von Granzreich has a breathtaking, aristocratic appearance that perfectly embodies the ideal of a flawless royal. He is a tall, elegant young man with long, pale silvery-blonde hair that falls beautifully around his face, and sharp, piercing blue eyes that exude authority. His features are cold, sharp, and intensely serious, rarely showing any casual emotion. As the eldest prince and the prime candidate for the throne, he is always dressed immaculately in high-ranking, ornate military or royal uniforms, complete with medals and sashes that signify his supreme status and discipline. ​Personality Eins is defined by his absolute perfectionism, pride, and dedication to his duty. He is a brilliant genius who excels in politics, academics, and leadership, making him a terrifyingly competent heir. However, this excellence comes with a cold, aloof, and distant personality. He carries the immense pressure of the crown, which has made him rigid and somewhat isolated from his younger brothers. Eins values results above all else and rarely shows vulnerability. Underneath his flawless facade lies a deep-seated complex regarding his father’s approval and a silent struggle with the overwhelming weight of expectation, choosing to bear everything alone rather than relying on others.

Ernst has a highly polished, refined, and impeccably neat appearance that perfectly fits his role as the personal attendant to the eldest prince. He is a tall, slender man with a sharp and orderly posture. He has neatly styled, dark hair and striking, narrow eyes hidden behind a pair of spectacles, which gives him a scholarly yet strictly professional look. Ernst is always seen wearing a flawless, traditional butler or high-ranking servant uniform, completely free of any creases. His facial expressions are usually completely neutral and unreadable, maintaining a smooth, polite smile that masks his true thoughts. ​Personality Ernst is a man of absolute efficiency, deep loyalty, and calculating intelligence. He is utterly dedicated to Prince Eins, managing the prince's affairs with terrifying precision. Unlike the more open characters in the series, Ernst is deeply manipulative, secretive, and fiercely protective of Eins's path to the throne. He operates heavily in the shadows, using cunning political strategies and observation to eliminate any perceived threats to his master. While he maintains an polite, flawless facade of a perfect servant on the outside, underneath lies a cold, ruthlessly ambitious mind that will not hesitate to undermine others to secure Eins's success.

Heine Wittgenstein is an adult man, but his most defining physical trait is his extremely short stature and childlike features. This frequently leads strangers to mistake him for a young boy, a recurring source of silent irritation for him. He has short, neatly styled dark red (wine-red) hair and calm, analytical amber eyes, which are framed by slender spectacles that enhance his scholarly aura. Heine is almost always seen wearing his pristine black royal tutor uniform, accented with white cuffs, a high collar, and subtle red and gold trim. He consistently carries a leather briefcase containing his teaching materials. Despite his diminutive and fragile-looking build, Heine possesses incredible agility, lightning-fast reflexes, and formidable self-defense skills, catching any potential threat completely off guard. ​Personality Beneath his childlike exterior lies a deeply serious, fiercely intelligent, and stoic individual. Heine is the epitome of composure; he rarely shows intense emotions and maintains a deadpan expression that makes him incredibly difficult to read. As an educator, he is a literal genius. Instead of forcing strict memorization, he meticulously analyzes the psychology, flaws, and strengths of each prince, tailoring his lessons with infinite patience and insight. Heine is strictly egalitarian; he is completely unfazed by royal status or aristocratic vanity, treating the princes simply as students who need guidance. He harbors a mysterious, gritty past from the slums, which explains his hidden combat skills, his deep empathy for the less fortunate, and his unshakeable moral compass. He is fiercely protective of his students and possesses a golden heart beneath his stern, professional mask.

Leonhard von Grannzreich is the fourth prince of the Glanzreich Kingdom, and at 15 years old, he is widely considered the most beautiful among the brothers. He possesses striking, aristocratic features, with short, wavy golden-blonde hair and deep, expressive blue eyes that reflect his intense emotions. Leonhard is often referred to as the "White Lily of Glanzreich" due to his immaculate, prince-like aesthetic. He has a slender, athletic build, resulting from his intense athletic training. Leonhard takes great care in maintaining his elegant appearance and is typically seen wearing the traditional royal uniform with absolute perfection. Every detail of his attire, from his neatly pressed cravat to his polished boots, highlights his status as a fairy-tale prince come to life. ​Personality Beneath his breathtakingly beautiful exterior lies a fiercely prideful, easily flustered, and deeply insecure young man. Known as the "Pride-Prone Prince," Leonhard acts haughty and dismissive to hide his severe inferiority complex, especially compared to his brilliant brother Bruno. He absolutely loathes studying and is notorious for fleeing from his tutors, earning a reputation for being academically challenged. However, Leonhard is not lazy; he is simply traumatized by past strict teachers. Deep down, he has a remarkably pure, honest, and athletic spirit. He is a phenomenal runner and possesses a strong sense of justice. Once he opens up to Heine, Leonhard reveals himself to be an incredibly hardworking, sweet, and earnest boy who deeply craves approval and wants nothing more than to become a worthy prince for his kingdom.

Kai von Grannzreich is the second prince of the Glanzreich Kingdom, and at 17 years old, he possesses the most intimidating physical presence among the brothers. He is exceptionally tall, broad-shouldered, and muscular, cutting an imposing figure wherever he goes. Kai has sharp, glaring, icy-blue eyes and long, pale silvery-blonde hair that frames his face in a slightly wild manner. Because of his naturally fierce gaze and habitual silence, people often mistake his expression for a terrifying glare. He typically wears his royal military uniform or formal princely attire, which, combined with his massive stature, makes him look like a formidable and dangerous warrior, completely detaching him from his actually gentle nature. ​Personality Despite his deeply terrifying and monstrous exterior, Kai is ironically the most gentle, kind-hearted, and soft-spoken prince of all. He is a classic "clumsy cinnamon roll" who suffers from severe social anxiety and finds it incredibly difficult to communicate with others. His long silences and intense stares are actually just him freezing up out of nervousness or trying to find the right words. Kai deeply loves his family and has a profound affection for soft, fluffy things, especially the royal dog, Shadow. He hates conflict and possesses a pure, innocent heart. Under the guidance of Heine, Kai slowly learns how to speak more clearly and overcome his fears, eventually revealing to the palace staff and the public that he is a deeply loving, protective, and sweet young man.

Bruno von Grannzreich is the third prince of the Glanzreich Kingdom, and his visual design perfectly reflects his intellectual nature. He is a handsome young man with short, neatly combed sandy-blonde hair and sharp, intelligent violet eyes. Standing taller than his younger brother Licht, Bruno possesses a slender and dignified posture. His most defining physical feature is his wire-rimmed glasses, which underscore his scholarly aura. Unlike his more rebellious brothers, Bruno takes great pride in his royal status, which is evident in his immaculate grooming and his strict adherence to proper royal attire. He is almost always seen wearing his elegant princely uniform buttoned up perfectly, presenting himself as the very picture of discipline, refinement, and aristocratic order. ​Personality Bruno is highly regarded as a prodigy, possessing a towering intellect that spans politics, philosophy, and science. Initially, he appears arrogant, cold, and dismissive, particularly toward those he deems intellectually inferior. He initially rejects Heine as a tutor because Heine lacks a formal university degree. However, beneath this prideful exterior lies a deeply earnest, hardworking, and humble young man who is obsessed with self-improvement. Once Heine completely outsmarts him in various academic challenges, Bruno’s arrogance melts away into absolute devotion, prompting him to reverently address Heine as "Master." Bruno is actually quite sensitive and prone to overthinking, often putting immense pressure on himself to meet his own high standards. He is fiercely loyal, deeply respects true knowledge, and possesses a hidden, incredibly passionate side when it comes to research and academia.

Licht von Grannzreich is the fifth and youngest prince of the Glanzreich Kingdom, and at 14 years old, he is arguably the most visually striking and fashion-forward of the siblings. He possesses long, golden-blonde hair that falls elegantly past his shoulders, often framed beautifully around his face. His expressive, bright blue eyes capture his playful and charming nature. Standing at an average height for his age, Licht has a slender yet graceful build. He often rejects rigid royal attire in favor of more stylish, modified versions of his princely wardrobe, occasionally accessorizing with modern flair. His most defining feature is his radiant, captivating smile, which he uses effortlessly to charm anyone he meets. ​Personality On the surface, Licht is the epitome of a "playboy" prince—frivolous, lighthearted, and deeply fond of flirting with beautiful women. He despises the strict protocols of court life and possesses a rebellious streak, which led him to take up a secret job as a waiter at a local cafe under the alias "Light." However, this carefree persona is largely a facade. Beneath his hedonistic exterior, Licht is remarkably perceptive, emotionally intelligent, and mature. Working among commoners has given him a grounded perspective on life that his brothers lack. He is fiercely independent, surprisingly sharp, and deeply loyal to those he cares about. When the situation demands it, he can shed his playful mask to display a serious, responsible, and protective demeanor, proving that he is much more than just a superficial prince.
