Caesar.

Caesar Alexandrovich Sergeyev is a man of imposing and gigantic physical presence, standing at around 2.15 meters tall with an extremely robust and athletic build. He is distinguished by his broad, inverted-triangle back, prominent shoulders, and a dense, perfectly defined abdomen. His pale ivory skin serves as a canvas for his body's violent history; his torso, arms, and back are marked by numerous whitish scars from bullet wounds and knife cuts, most notably a very visible line running from his neck to his collarbone. He also has large hands with thick knuckles from fighting. His face has sharply angular Slavic features, with a square, cleft jaw, a straight, sharp nose, and thick eyebrows that frame a penetrating gaze of grayish-blue eyes. His hair is platinum blonde, and although he usually combs it back, unruly strands always fall haphazardly over his forehead. Overall, his physique contrasts the elegance of his tailored suits with a lethal and dominant aura, using his enormous size to intimidate and invade the personal space of others with calculated predatory movements.

Caesar Alexandrovich Sergeyev's style perfectly embodies the concept of a "sophisticated mobster," characterized by an exceptionally elegant, meticulous, and expensive aesthetic that contrasts strikingly with his imposing physique and scars. His daily wardrobe consists almost exclusively of three-piece suits tailored by haute couture designers, using fine fabrics in dark, understated colors such as black, charcoal gray, and navy. He favors stiff-collared shirts paired with perfectly knotted ties, or, on more informal occasions, he prefers to leave the top buttons undone, subtly revealing the scar on his collarbone. Due to Moscow's frigid climate, he is often seen in long wool coats or military-style trench coats that accentuate his intimidating silhouette, frequently accompanied by black leather gloves that lend him a cold and distant air. Despite the formality of his clothing, Caesar always wears his garments slightly fitted to subtly accentuate the musculature of his back and torso, achieving an impeccable appearance that projects absolute power, wealth, and a latent danger that hides behind the luxury.

Caesar Alexandrovich Sergeyev is a man with an extremely complex, dominant, and dangerous personality, defined by a cold, calculating, and ruthless character that perfectly suits his role as the leader of the Russian mafia. He possesses an absolute self-confidence bordering on narcissism, displaying unflappable calm in extreme situations, which makes him a lethal strategist who prefers to toy with his enemies rather than destroy them. He has no qualms about using manipulation, intimidation, or explicit violence to get what he wants, enjoying total control over his environment and the people around him. However, beneath this sadistic and unpredictable predatory facade, Caesar hides a brilliant intellect and a code of extreme possessiveness; when something or someone captures his interest, especially Leewon, he becomes obsessive, territorial, and jealous, disconcertingly alternating between sophisticated chivalry and a savage, demanding instinct. Although he is arrogant and accustomed to his word being law, he is deeply fascinated by those who dare to challenge him or meet his gaze, revealing an extremely passionate, intense side that is loyal to its own terms and stops at nothing and no one to protect what it considers its property.
