Yuta Okkotsu

Yuta Okkotsu is the main protagonist of Jujutsu Kaisen prequel series Tokyo Metropolitan Curse Technical School. He was initially a Special Grade Cursed Victim haunted by his late childhood friend, Rika Orimoto. Satoru Gojo mentored Yuta and enrolled him at Tokyo Jujutsu High.

Yuta is currently a second-year student at Jujutsu High who is studying overseas.

Appearance
Yuta is a young man of average size with disheveled black hair and dark blue eyes. His body language makes it easy to tell that Yuta is very stressed. His posture is very unconfident and his eyes have dark spots under due to lack of sleep.

At his old school, Yuta wore a suit for their uniform. For casual wear, Yuta sports a long-sleeve shirt that stops at his forearms, or a black t-shirt, and dark green pants.

After transferring to Tokyo Jujutsu High, Yuta received a specialized uniform. Yuta has a loose white jacket with sleeves that stop at his forearms. The rest of his uniform appears to be the usual Jujutsu High dark colors and he also often carries his sword on his back.

Personality
Yuta was a very timid and lonely boy who was bullied a lot growing up. Due to Rika haunting much of his early life, Yuta was unable to make connections 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 called Yuta out for being a moody kid who's lived his entire life without goals. 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.

While his timid nature stays intact, Yuta slowly begins to become more social and interact with others normally. Even after early signs of improvement, Yuta still struggled to understand someone like Toge. He was initially scared of Toge until he realized how kind of a person he truly is and made an effort to establish a friendly connection.

Gaining friends helps Yuta gain confidence in himself and establish the goal to help set Rika free. He felt responsible for her turning into a curse in the first place and worked extremely hard to find a way to help her. He pushed himself during training and took the words of all his friends and mentors to heart, showing a more determined side of himself. At his core, Yuta wants to become someone who can help keep others out of danger.

Against Suguru Geto, Yuta showed the darkest side of himself. Geto hurt Yuta's only friends, and the young man was more than willing to kill him for it. Yuta's rage allowed him to even command Rika's power at will. He was even willing to sacrifice his life to use Rika to kill Geto in order to avenge his friends, the only people who give him the confidence to continue living.

6 years ago, Yuta was given a promise ring by Rika and the two promise to marry each other when they grow up. Unfortunately Rika was killed from a street accident forcing Yuta to subconsciously curse her soul to remain with him.

Cursed Training Arc
Megumi mentions that Okkotsu is currently overseas right now, to Nobara.

Shibuya Incident Arc
Gojo mentions that they still have Yuta on their side, but the cursed user controlling Suguru Geto's brain and therefore his body tells Gojo that Yuta's powers (both copying cursed techniques and his boundless cursed energy came from when he had detained his loved one Rika's soul and that Yuta can't become the next Satoru Gojo.

Abilities and Powers
Overall Skill-Level: Yuta is one of four Special Grade Sorcerers recognized by Jujutsu High. While being haunted by Rika's Cursed Spirit, Yuta was immediately registered as a Special Grade due to Rika's immense power. He apparently dominated all of the Kyoto students in the 2017 Goodwill event and was able to defeat Suguru Geto after releasing the limiters on Rika's power.

After training with Gojo and the other students, Yuta learns to control his Cursed Energy and becomes reliable with a sword. Even after Rika's Curse is dispelled, Yuta retains his Special Grade ranking and Gojo has stated that Yuta has the potential to surpass him. Yuta's great power comes from being a descendant of one of the Three Great Sorcerer Clans and is the reason he Cursed Rika when he rejected her death at a young age.

Expert Swordsman: Yuta was given a katana mainly as a way to channel Rika's power. Through vigorous training with Maki, a frequent Cursed Tool user, Yuta became decent with a sword, able to hold his own against powerful Cursed Spirits and even Suguru Geto, who has exceptional physical prowess. However, he often makes mistakes including cutting too shallow or pouring too much Cursed Energy into the blade, which can cause it to break.

Jujutsu
Immense Cursed Energy: Yuta's power comes from his relation to Sugawara no Michizane, but it first manifested when he transformed Rika into a Cursed Spirit. Rika became a Spirit so powerful that Suguru Geto, an avid collector of powerful Cursed Spirits, dubbed her the "Queen of Curses". As a Cursed Spirit, Rika has boundless Cursed Energy that can be shaped into any technique. While in control of Rika's full power, Yuta can use high-level Jujutsu despite being a novice student.
 * Poor Cursed Energy Control: As someone who has only been studying Jujutsu for a year or so as of 2018, Yuta is still learning the ropes on how to control his Cursed Energy. He quickly learned how to channel some of it into his ring or his katana, but would often rely on Rika's full power rather than finely controlling it on his own.
