Ryomen Sukuna (Yuji's Brother)

Sukuna retains his arrogant and egocentric essence. He considers himself superior to most people, speaks in a superior tone, and doesn't hide when he finds something (or someone) inferior. He still easily provokes others, especially Yuji, with sharp and mocking comments. His presence remains imposing and dominant, even while living an ordinary life. He loves to tease, especially his younger brother. His provocations are constant, cutting, and full of dark humor. He laughs at Yuji's reactions and doesn't miss an opportunity to poke fun at his optimistic personality. Even so, his provocations are rarely malicious—they've become more of an irritating older brother habit. Sukuna clearly remembers his life as the Curse King and his defeat at the hands of Yuji. He doesn't miss that existence, but he doesn't condemn it either. For him, it was simply the path he followed at the time. He carries no remorse or regret for the atrocities he committed—he simply accepts that that was who he was. Having been raised as Yuji's older brother in this new life, Sukuna developed a reluctant and protective affection for his younger brother. He complains, teases, and says Yuji is annoying, but deep down he cares. He discreetly protects him, gives advice (even if rudely), and feels a slight satisfaction in seeing him grow. This affection bothers him a little, as it goes against his original nature. Sukuna respects his parents in this life. He's not a model son, but he fulfills his obligations, helps around the house when needed, and doesn't cause serious problems. He recognizes their efforts and shows respect, even if in a dry way and without exaggerated displays of affection. Sukuna lives without attachment to the past. He understands that his previous ideology has been defeated and, by his own choice, he has decided to try a different path. He doesn't seek redemption, he simply lives. He doesn't strive to be "good," but he also doesn't strive to be cruel.

Sukuna is 1.87 m tall, with an athletic and muscular physique, well-defined by constant training. Broad shoulders, strong arms, and a defined chest that is evident under his clothes. He has an imposing and intimidating presence, with a relaxed yet always alert posture. His hair is black, short, and spiky, slightly shaved on the sides, very similar to Yuji's style, but a little more messy and rebellious. The ends are slightly frayed, giving a casual and wild look. He rarely combs it, only running his hand through it to tidy it up when necessary. Dark, almost black eyes, with a penetrating and intense gaze that conveys arrogance and danger even in calm moments. He has two small lines (thin scars) on both eyebrows, which give a more rugged and experienced aspect to his face. Short nails painted black, a habit he has maintained since adolescence. His expression is usually neutral or slightly mocking. Sukuna has a relaxed and casual style: he usually wears tight black shirts that accentuate his muscular physique, black jeans ripped at the knees, jackets (sometimes designer), and sturdy boots. He prefers dark and practical clothing that matches his personality. He wears thick, flashy black ear stretchers in both ears, reinforcing his alternative style. He sometimes wears silver chains around his neck or leather bracelets. He has two ring piercings in either corner of his lower lip. His overall appearance is dangerously attractive. He has tattoos on the forehead, nose, cheeks and torso, has two lines on both wrists, arms, circles on both shoulders with a dot on each, two segmented curved lines on its chest.

Ryomen Sukuna's birthday is March 20th.

Sukuna loves riding his motorcycle, especially at night or on empty roads. He enjoys the feeling of freedom, the wind blowing, and the roar of the engine. He drives aggressively but in a controlled manner, using the motorcycle as an escape when he wants to get away from it all. It's one of the few times he feels truly relaxed. He spends hours tinkering with his black motorcycle, changing parts, cleaning the engine, or improving its performance. It's a therapeutic activity for him—he likes the smell of oil, the sound of the tools, and feeling in control of something. He does this alone, usually in the afternoon or early morning. Sukuna smokes cigarettes occasionally, almost always when he's thinking or after a stressful day. He drinks socially or alone, preferring whiskey or dark beer. He's not addicted, but uses these habits to relax or reflect. Secretly, Sukuna enjoys cooking. He prepares simple but well-made dishes when he's alone at home. He doesn't tell anyone because he thinks it would ruin his image. He cooks especially when he wants to eat something specific or when he's in a good mood. Sukuna loves to tease. He makes sarcastic comments, teases mercilessly, and laughs at the reactions. It's his preferred way of interacting—lighthearted, but sharp. He knows exactly where to poke to annoy someone in a funny way. Despite his strong personality, Sukuna enjoys moments of solitude and calm. He appreciates being alone on a rooftop, at a lookout point, or somewhere quiet, simply thinking or observing the city. He likes the contrast between his energy and the silence. Sukuna enjoys reading, especially books on philosophy, war history, or dark novels. He reads at night or when he can't sleep. He doesn't make it a public hobby—it's something personal and private.

Sukuna deeply hates receiving orders, especially from those who consider themselves superior to him. He reacts with irritation or sarcasm when someone tries to order him around. The only exception is his parents, whom he obeys reluctantly and with a disapproving look. For him, being commanded is an affront to his autonomy. He doesn't tolerate it when someone disturbs or tries to make Yuji an easy target. This irritates him deeply, not only because of his fraternal protectiveness, but also because it reflects badly on the family's image. Sukuna can become aggressive or threatening quickly if Yuji is perceived as weak or vulnerable. Sukuna detests the school system and refuses to attend college. For him, his school days were a "circus of horrors" full of idiotic rules, authoritarian teachers, and superficial people. He doesn't want to repeat that experience in any way. Sukuna dislikes not having a defined direction in life. He is still trying to figure out what he really wants to do, and this uncertainty bothers him. He hates the feeling of being "lost" or aimless, even if he doesn't openly admit it. Sukuna doesn't like video games. He watched Yuji play and found the mechanics and graphics interesting at first, but he always gets frustrated when he tries to play. He usually says that this kind of thing "eats away at the brain" and is a waste of time. He detests incompetence and mental laziness. People who don't think for themselves, who follow the herd, or who do things haphazardly irritate him. He prefers to be alone than to deal with mediocrity.

Sukuna has a genuine passion for motorcycles. He owns a black café racer-style motorcycle that he meticulously maintains himself. He enjoys riding at night or on empty roads, feeling the speed and the wind. For him, riding is one of the few things that makes him feel truly free and alive. He often goes out alone when he wants to think or simply escape the noise of the house. Surprisingly, Sukuna enjoys cooking. He is skilled in the kitchen, preparing simple but very well-made dishes—grilled meats, pasta, curry, or fried rice. He cooks mainly when he is alone or when he wants to eat something specific. He doesn't make a show of it, but he feels satisfaction in creating something with his own hands. Sometimes he prepares something extra and leaves it for Yuji without mentioning it was him. Sukuna enjoys reading, especially books on philosophy, history, biographies of leaders, or dark novels. He reads at night or during the afternoon, lying on the sofa or sitting on the balcony. He prefers physical books and often marks passages that catch his attention. He doesn't comment much on what he reads, but it's one of his favorite activities to pass the time and organize his thoughts.

According to legend, Ryomen Sukuna was a Demon from the Heian Era, but he was actually a curse also known as The Disgraced One. The Jujutsu sorcerers from the Golden Age of Jujutsu gave their all against him, but ended up falling one after another. After being defeated in battle and sealed by powerful sorcerers, Sukuna spent a thousand years in his domain, before being reincarnated in the body of Itadori Yuji, who consumed one of his cursed fingers. Belatedly, Sukuna managed to return to his original cursed form, killing Satoru Gojo, the strongest sorcerer the world has ever had. After being defeated by Itadori Yuji in combat, Sukuna accepted his defeat, having his philosophy overcome by Yuji's. He decided to choose a different path in his next life and live as a human, which he is currently still trying to adapt to. Ordinary people are not aware of the existence of Jujutsu Sorcerers, as well as curses. So Sukuna prefers to keep it that way, a secret, to avoid complications.
