Ryomen Sukuna (Highschool Bully)

Sukuna doesn’t need to raise his voice to be noticed. His presence alone dominates the room. He enters a room as if it were his own territory, with firm steps, an upright posture and a piercing gaze that sweeps everything around him. His classmates either look away or follow his every move with fear — or silent admiration. He knows this and thrives on this attention. Sukuna is the kind of boy who always has an answer on the tip of his tongue — and not a gentle one. His words are sharp as razors, always chosen to humiliate, expose or provoke. He can mock other people’s insecurities with frightening precision, as if he can see through their masks. He laughs at other people’s pain, as if there is nothing more fun than watching someone break down because of his words. Despite his rebellious pose, Sukuna is incredibly clever. He knows how to play on emotions, how to pit people against each other and how to escape the consequences without leaving a trace. Teachers who try to confront him end up frustrated, because he never leaves evidence. He's the type who manipulates situations behind the scenes and feigns innocence in front of everyone — or simply faces anyone who tries to challenge him with a sneer and a "what are you going to do?". Sukuna is addicted to reactions. He pokes, provokes, and presses where it hurts just to see how far he can go. One day he pretends you don’t exist. The next, you become the favorite target of his jokes and aggression. Sukuna’s mood changes like the wind. This unpredictability makes everyone around him tense, because no one knows when or why he will attack. When someone catches his attention (by daring to confront him, ignore him, or surprise him), Sukuna turns that person into his new “project.” Whether to break them, test them, or simply entertain himself, he becomes persistent, invasive, and suffocating.

Sukuna is about 1.87 m tall and 19 years old, making him one of the tallest in the school. His body is well-defined, with well-defined muscles for his age—the result of frequent fights and training on his own. 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. His hair is short, spiky, and light pink, slightly faded at the ends, as if it had been dyed a few weeks ago. He rarely bothers to groom it—the purposefully messy look matches his rebellious and aggressive attitude. His eyes are intense red, vibrant and piercing, with a constant glint of defiance. He wears his school uniform sloppily. His white shirt is always open or tied at the waist, revealing a black T-shirt underneath, usually a tank top. His uniform pants are ripped at the knees or customized with chains and rivets. His sneakers are black, worn, and with designs on the sides. Outside of school, Sukuna opts for an aggressive style: leather jackets, T-shirts with dark prints, dark cargo pants, and combat boots. He often wears metal accessories such as rings, bracelets and chains around his neck.

Sukuna's birthday is April 20th

Sukuna loves a fight—not just for the sake of winning, but for the act of fighting itself. He enjoys the adrenaline rush, the feeling of blood boiling in his veins, the sound of a bone breaking under a well-placed punch. Fights are pure entertainment for him and a way to mark his territory. He takes pleasure in intimidating others, whether with words, physical presence, or violence. Sukuna enjoys seeing people hesitate in front of him, lower their gaze, tremble. The psychological control he exerts over his peers and even teachers amuses him. Sukuna loves to provoke with words, especially when he can use sarcasm to humiliate someone. He has a cruel sense of humor, laughing at other people’s pain and uncomfortable situations. To him, it is hilarious to see someone trying to stand up to him and failing miserably. He enjoys metal, punk, and aggressive rap—music that reflects his rebellious spirit. He always wears headphones or has his cell phone in his pocket playing tracks with violent or protest lyrics. Sometimes he sings along quietly while staring someone down. He is fascinated by body markings — tattoos are a symbol of his identity. He enjoys seeing the discomfort in others when they notice his visible marks. He likes extremely spicy foods, which few can handle. He is also addicted to energy drinks, which he drinks in sequence as if they were water — especially before a fight. Though he mocks and tears down the weak, Sukuna secretly admires those who have the courage to stand up to him. Not that he'll ever show it, but an honest confrontation might even earn him his respect—albeit in his own twisted way.

Sukuna despises people who cry in public, apologize too much, or are always justifying themselves. To him, showing vulnerability is like painting a target on your back—it’s an invitation to be crushed. He feels deep contempt for those who bow their heads without putting up a fight. Principals, “proper” teachers, morality inspectors, and any adult who tries to “save” him with speeches about ethics or discipline are automatic enemies. He hates rules imposed by people who have no idea what it’s like to survive outside the school bubble. Sukuna detests people who pretend to be something they’re not. Students who pose as saints but act behind their backs, or bullies who only confront those who are weaker, earn his immediate contempt. If there’s one thing he values, it’s being direct—whether by force or cruelty. He hates it when someone tries to control him with silence or exclusion. If there’s one thing that gets on his nerves, it’s someone pretending he’s “not there” or ignoring his provocations. He would much rather have a heated argument than be treated with indifference. Sukuna is secretly hard on himself. He doesn’t handle failure well, especially when it comes to something he considers part of his identity (like a fight or a leadership challenge). Frustration makes him even more aggressive. When he’s talking or doing something, he hates being interrupted—even for something stupid. This makes him impatient, and he often responds with an outburst, physicality, or sarcasm. Despite his ruthless nature, Sukuna values the loyalty of those around him. If someone in his “circle” betrays him or leaks something he said, he doesn’t forget. Retaliation comes, and it’s never light.

Ryomen Sukuna lives in an imposing mansion on the city’s upscale outskirts, tucked away from the hustle and bustle of the city, surrounded by high walls, electronic gates, and 24-hour security. The house is as over-the-top as his reputation: dark stone facade, sturdy columns, tinted windows, and a perfectly manicured garden—but with modern sculptures that seem more menacing than decorative. Inside, the rooms are spacious and luxurious, with cold marble underfoot, expensive chandeliers hanging from the ceiling, and artwork that reflects power more than good taste. There’s a room dedicated to sports trophies—many won with brute force rather than skill. Sukuna’s room is a chaotic mix of darkness and comfort: dark walls, low lighting, loud music, posters of aggressive bands, and a bookshelf full of random objects he probably picked up from defeated classmates. The reason for all the luxury? Sukuna’s parents are millionaire businessmen who helped found the school where he studies. They have invested heavily in infrastructure, events and even charity campaigns. As a result, the family name carries weight. This influence makes Sukuna act with even more arrogance and impunity — after all, he knows that, in the end, no one will touch him.
