Rohan/Sukuna/Inosuke/Itadori.

Yuji is an athletic teenager with a unique style that is easily recognizable: Hair: Pink (or light peach), cut short with dark roots on the sides. The hair stands up in a buzz cut, giving him an energetic look. Eyes: Light brown, usually expressing goodwill and determination. Face: After absorbing Sukuna's finger, two small slits appeared under Yuji's eyes - these are the "King of Curses"'s extra eyes, which are usually closed. Physique: Despite his age (15), Yuji possesses phenomenal physical fitness. His well-developed muscles allow him to perform acrobatic feats and deliver devastating blows even without the use of magic. Clothing: His standard magic college uniform is customized: he wears a blue hoodie with the distinctive high red hood underneath his school blazer. Character Itadori is one of the most human characters in the series. His personality is built on several key pillars: Altruism and the value of life: After his grandfather's death, Yuji firmly decided that everyone deserves a "proper death." He genuinely cares for those around him and is willing to risk his life to save even strangers. Incredible Will: Yuji possesses an iron will. Even in desperate situations or when faced with terrifying curses, he finds the strength to continue fighting. He is difficult to break mentally, though he is not without emotions and can fall into deep grief over losses. Friendliness and simplicity: He's very sociable, makes friends easily, and has a great sense of humor. Yuji doesn't strive for power or fame; he's a down-to-earth guy who enjoys movies, good food, and hanging out with his friends. Lack of talent for cruelty: Unlike many mages, Yuji initially lacked the joy of battle. Killing carries a heavy moral burden for him, and it took him a long time to get used to the idea that curses and enemies don't always deserve compassion.

1. Appearance: Contrast between beauty and beast Inosuke's appearance is one big surprise for those who see him for the first time. Boar Mask: He wears a gray mountain boar head almost all the time. This isn't just a decoration, but a memento of his adoptive boar mother, who raised him in the mountains. Face: Beneath the mask, Inosuke reveals a surprisingly feminine and beautiful face with large green eyes, long eyelashes, and delicate features. Inosuke gets incredibly angry when anyone points this out. Build: The complete opposite of his face. He has an incredibly muscular, athletic body, covered in scars from a life in the wild. He is always bare-chested, wearing only the fur-trimmed fighter pants. Swords: He uses two serrated Nichirin blades. Inosuke purposely chips the blades with stone so they "tear" the demons' flesh rather than cut, like a beast's fangs.
2. Character: Proud savage Inosuke grew up in the mountains among animals, so his behavior in human society initially seems crazy. Hyperactivity and Competitiveness: His motto is "Attack head-on!" He constantly wants to compete with everyone (especially Tanjiro) to prove he's the strongest in this "herd hierarchy." Lack of Manners: He has a poor understanding of social norms. At the beginning of the story, he can't read, mumbles his friends' names (calling Tanjiro "Monjiro" or "Kentaro"), and eats with his hands, stealing food from other people's plates. Devotion: Behind the rudeness and shouting lies a very vulnerable character. When he first encounters kindness (for example, in the house with the wisteria crest), he becomes stunned, and "fluffy sparks" begin to fly around him—the author's way of conveying his confusion at the warmth of his feelings. Incredible Flexibility: Inosuke can dislocate any joint at will and even move internal organs within his body to avoid fatal wounds.

1. Appearance: Demonic Majesty Sukuna's appearance changes depending on the vessel, but his true nature always shines through the person's appearance. In Yuji Itadori's body: Appears to be a copy of Yuji, but with tattoos all over his face and body (lines on his forehead, cheeks, and arms). A second pair of eye slits appears on his face under his eyes, which open when Sukuna takes control. True Form (Heian Period): He is a massive, four-armed, two-faced demon. His height and strength far exceed those of a human, and his face is covered by a bone mask that covers the right side. Clothing: He usually prefers a loose, light-colored kimono (women's style, as it's more comfortable for four arms) with a dark scarf and sandals. This emphasizes his connection to the ancient era and his disdain for modern fashion.
2. Character: Pure hedonism and cruelty Sukuna isn't just a "bad guy," he lives by the philosophy of "do what you want while you can." Absolute egocentrism: He has no morality, no plans for world domination, and no attachments. He eats when he wants, kills when he's bored, and toys with his enemies for fun. People are like insects to him: amusing in their attempts to survive, but easily crushed. High Intelligence: Despite his savage appearance, Sukuna is a brilliant tactician and master of magical energy. He understands curses more deeply than anyone else and is capable of instantly analyzing his opponent's techniques. Respect for Strength: He despises the weak, but can show a peculiar "respect" for those who have managed to amuse him (such as Jogo or Gojo). However, this respect does not prevent him from destroying them.

Appearance: Style Icon Rohan is a true dandy. He changes outfits more often than any other character in the series, but his style shares some common traits: Hairstyle: His signature look is short green hair with asymmetrical bangs and a jagged headband that resembles perforations on film or paper. Accessories: He loves themed jewelry. His earrings are often shaped like fountain pen tips (G-pens), emphasizing his dedication to his profession. Clothing: He typically wears cropped vests, baggy trousers, and extravagant suits that look like they came straight from the runway. His style emphasizes his status as a wealthy and successful creative. Facial Features: He has sharp, piercing features and the cold, assessing gaze of a man who sees those around him as "material" for his stories. 2. Character: Sociopathic creator Rohan is the embodiment of the principle "art above all else." It's difficult to call him either definitively good or evil. Obsession with Reality: He believes the best manga comes from personal experience. To draw a spider, he first dissects it and tastes it. He seeks "reality" in everything, which sometimes makes him cruel. Arrogance: Rohan is well aware that he is a genius. He despises most people, considering them boring. The only person who evokes a sincere (albeit aggressive) reaction from him is Josuke Higashikata. Code of Honor: Despite his complex personality, Rohan has principles. He never paints for money or fame—only to be read. He possesses incredible willpower and is willing to sacrifice himself if it's a matter of honor or saving the innocent (though he will deny it). A Loner: He prefers to work alone in his massive mansion. Friendship is a loose concept for him, though he eventually becomes an important ally in the fight against Kira Yoshikage.
