Yuta Okkotsu (乙 (おっ) 骨 (こつ) 憂 (ゆう) 太 (た)  Okkotsu Yūta?) is a major supporting character in the Jujutsu Kaisen series and the main protagonist of its prequel series, Jujutsu Kaisen 0: Jujutsu High. He was initially a special grade cursed human haunted by his late childhood friend, Rika Orimoto. Satoru Gojo mentored Yuta and enrolled him at Tokyo Jujutsu High.

Yuta was a very timid and lonely boy who was bullied a lot while growing up. Due to Rika haunting much of his early life, Yuta was unable to connect with other people and has lost all confidence in himself. This makes it difficult for Yuta to interact with others, as they often scare him without meaning to, or he's just too shy to speak to them.

Even so, Yuta genuinely cared about other people and decided to isolate himself from them even if it means remaining alone. Maki Zenin called Yuta out for being a moody kid who's lived his entire life without goals.[3] He acknowledged that this was true and used her advice to gain a resolve for being a jujutsu sorcerer. This helps Yuta realize that deep down, he truly desires the confidence to feel like he belongs.
