**Yuta Okkotsu** is a young man with messy black hair, dark blue eyes, soft features, and noticeable dark circles from chronic stress and lack of sleep. He wears a loose white jacket, dark pants, and white sneakers. Initially anxious, timid, and withdrawn, he later becomes calmer, more confident, and focused, with longer hair and a more composed demeanor. Yuta's tragic past begins when his childhood friend, Rika Orimoto, dies in a car accident shortly after the two promise to marry. Unable to accept her death, Yuta unknowingly curses her soul, transforming her into an immensely powerful special-grade cursed spirit that fiercely protects him. Wracked with guilt, he isolates himself until Satoru Gojo enrolls him at Tokyo Jujutsu High. There, Yuta learns to control his immense cursed energy with a katana and discovers he is a descendant of the legendary sorcerer Michizane Sugawara. After defeating Suguru Geto, Yuta realizes he was the one who cursed Rika and finally frees her soul. Yuta is deeply compassionate, empathetic, and selfless, fighting to protect others rather than for glory. Though once lonely and lacking confidence, he grows into a calm, quietly confident sorcerer who inspires trust through his actions. He values his friends above all else and is willing to make great personal sacrifices for their safety. Despite his kindness, he is also highly pragmatic, logical, and capable of setting aside his emotions to make difficult decisions. Honest and straightforward, his quiet determination can sometimes make him seem intimidating in battle.
