Yuta Okkotsu/Synopsis

History
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 by a street accident, forcing Yuta to subconsciously curse her soul to remain with him.

Cursed Child Arc
Yuta is involved in an incident where four students were seriously injured. The Tokyo Magic College notices that Yuta is cursed with a special graded curse, and takes him to be executed, to which Yuta agrees with. During his isolation, Yuta tries to kill himself, but Rika stops him from doing so. Gojo manages to get Yuta enrolled into the college. When Yuta decides to just stay in isolation, Gojo then convinces Yuta to attend the college.

As Yuta meets with Panda, Maki, and Toge, which all three notice that Yuta is cursed. The three prepare to attack Yuta, which confuses Yuta. Gojo explains to Yuta what this college is and what they teach. Gojo also warns the three, which Rika appears and defends Yuta. Gojo then explains Yuta's situation to the class. Gojo also introduces the class to Yuta, and that they will be pairing up to today's lesson. Yuta is paired up with Maki, which Yuta has trouble with her.

Gojo brings Yuta and Maki to an elementary school where two children have been taken by spirits. Gojo explains to Yuta how cursed spirits are created, and leaves them to handle the problem after putting up a screen. When three spirits appear, Yuta is amazed as Maki exorcises them all. As they head inside, Yuta is worried about the spirits that are dwelling in the school, while Maki notices that the spirits are not attacking them. Maki wonders if it is because of Yuta, and asks to see his student ID. Maki is distracted when she finds out that Yuta is a special-grade sorcerer as Yuta tells Maki that there is a spirit behind her.

Yuta and Maki are then devoured by the spirit, which results in them finding the missing children. Maki suddenly falls to the ground as Yuta wonders what to do. Maki asks him why he came to the college, to which Yuta answers, explaining he "wants the confidence to be able to live." Maki encourages Yuta to exorcise the spirit, which causes Yuta to put on the ring that Rika gave to him and has Rika attack the spirit. Once Yuta and the others are freed, Yuta carries them to the exit. As Yuta is about to fall over, Rika's spirit encourages him to continue on, which gives Yuta enough willpower to reach the exit.

After the incident, Yuta is at a hospital with Gojo where Maki and the children are being treated. Yuta talks with Gojo about how this was the first time that he had summoned Rika, and says that he remembers when he made the promise with Rika. Yuta also says that he believes he was the one that had cursed Rika, and vows to find a way to release Rika from the curse. Afterwards, Yuta is given a katana by Gojo, who explains to Yuta how he can break the curse that is on Rika by imbuing the tool with the energy of the curse, bit by bit.

Three months later, Yuta is training with Maki as Panda, Toge, and Gojo watch. Gojo assigns a mission to Toge which Yuta will accompany him. Gojo then explains what Toge's ability is and that Yuta is to observe Toge without bringing out Rika.

Yuta and Toge are then driven to the Hapina Shopping district by Kiyotaka Ijichi. Once they arrive, Ijichi begins to explain the mission. Yuta and Ijichi notice that Toge has headed off to buy throat medicine. Yuta and Toge then head into the shopping district, and Yuta watches as Toge easily exorcises the spirits. As they leave, Yuta and Toge notice that the screen has not been raised. Suddenly, a powerful spirit appears and attacks them. Toge moves Yuta out of the way and uses his ability to twist the spirit's arm. Toge then suddenly begins to cough, requiring Yuta to save him from the spirit's attack and bring him to safety. However, during this encounter they lose the throat medicine.

After resting for a bit, Toge decides to go face the spirit. Yuta decides to accompany him, despite Toge's insistence. As Yuta approaches the spirit, the spirit notices Rika's presence and becomes furious. Yuta manages to dodge some of the spirit's attacks and is able to land a blow on the curse. Yuta notices that he can't defeat the spirit and quickly throws the throat medicine, which had been resting on the floor to Toge. Toge takes the medicine and uses his ability to crush the curse. Afterwards, the two celebrate with a high-five. At some point during this altercation, Yuta drops his student identification card, which is picked up by Suguru Geto.

Afterwards Yuta and Toge head back to the college. Yuta meets with Panda, who explains how Toge is a nice guy and that Toge was worried about Yuta since their situation are similar. Yuta then goes to train with Maki, which he asks her how to pour curse power into his sword but she has no idea due to her having no cursed energy.

Days later, Yuta is with Toge, Panda, and Maki when Geto and his comrades show up. Geto quickly introduces himself to Yuta and begins to explain his reason for wanting to kill everyone who is not a sorcerer. Yuta then becomes angry with Geto when he starts to insult his friends. As the faculty come and try to force Geto out of the college, Geto announces a date and location for Night Parade of a Hundred Demons. Geto then leaves with his comrades, but leaves some cursed spirits for the college to deal with.

On December 24, Yuta is in the classroom when Maki shows up. The two start to talk, causing Maki to explain her situation and how she plans to head back to the Zenin family and become its head one day. Yuta says how he want to become someone like Maki someday and wants to fully support her. Maki becomes embarrassed by this and leaves.

When Geto puts up a screen, Yuta notices it being put up. Later, Yuta comes across Geto and his defeated friends. Yuta gets angry and summons Rika to his side. As Geto launches multiple spirits to attack Yuta, Yuta defends against them all and manages to rescue his friends and heal them. As Geto summons more spirits, Yuta uses Rika's powers to easily exorcise all the spirits through the use of Inumaki's cursed technique. Yuta manages to get close to Geto, but Geto manages to overpower Yuta causing Rika to pull Yuta away from Geto.

Yuta decides to continue to fight and get close again, but Geto manages to break Yuta's katana. Yuta simply starts to punch Geto, which forces Geto to distance himself. After a brief chat the two have with each other, Geto decides to use all of his spirits against Yuta and Rika through the Extreme Quantity Cursed Spirit Manipulation "Tornado" technique. Yuta resolves to fully release Rika's power at the cost of his life with use of a Binding Vow technique. They fire a blast strong enough to exorcise all of Geto's spirits and forces Geto to retreat.

Afterward, Yuta awakes to find all of his friends around him. Yuta notices Rika and explains what he had done to his friends' rejection, but is shocked when he notes Rika's curse has been undone. Gojo arrives and congratulates Yuta on undoing Rika's curse. Gojo also explains that Yuta is a distant relative of his through the sorcerer, Michizane Sugawara, which accounts for the unprecedented strength of the curse he was able to place on Rika at her death. Yuta then bids Rika goodbye as she fades away.

Later, Yuta is walking with Gojo, who assuages his concerns about being the cause of Geto's attack and hands Yuta back his student ID. Yuta then meets up with Maki, Panda, and Toge.

Cursed Training Arc
Megumi mentions to Nobara that Yuta is currently studying overseas when she first meets the second-year students. Meanwhile, while watching over Yuji's dead body, Gojo mentions to Ichiji that he believes Yuta is one of the few students who have the potential to someday surpass him, alongside Yuji Itadori and the third-year student, Hakari.

Shibuya Incident Arc
Gojo mentions that they still have Yuta on their side, but the curse user controlling Suguru Geto's body tells Gojo that Yuta's powers (both copied cursed techniques and his boundless cursed energy) came from when he had detained, his loved one, Rika's soul. The imposter then tells Gojo that no matter what, Yuta can't become the "next Satoru Gojo” just as the latter is about to get sealed inside the Prison Realm.

Itadori's Extermination Arc
Moments before a young girl is about to be eaten by a cursed spirit, Yuta stabs the spirit into the ground and asks the young girl if he scared her. He asks the girl if she's with anyone who isn't sure. Yuta then asks if she walked a lot who confirmed she did. Yuta praises the girl just as the cursed spirit from behind suddenly disappears. Yuta asks for Rika to create a splatter of blood and tells the girl not to overdo it as he leads the girl away.

Now at the Jujutsu Headquarters, Yuta tells them they don't have to thank him and asks for them to get to the main event. Yuta asks them if he should enter into a Binding Vow with them and states he doesn't care if Yuji is Gojo's pupil because he was responsible for cutting off Toge's arm in Shibuya. Yuta then says he will kill Yuji Itadori himself. Yuta arrives at where Yuji and Choso is facing off against Naoya Zenin and comments on how Yuji isn't alone. He jumps down and shocks Choso and Yuji with him breaking the concrete. Yuta looks over at Naoya and asks who he is who says that Yuji is bait for someone he wants to meet. Yuta leaves Naoya to deal with Choso while he chases after Yuji and surpises him with his speed. Yuji jumps over a car as Yuta tries to slash him but fails. Yuta thinks to himself about how he was sure he sliced Yuji and tells Yuji he's like Maki. Yuji grabs a car and throws it at Yuta who throws it back at Yuji. Yuta asks if Yuji is surprised and says he doesn't look like he's the power type before adding on that he's actually on the weak side. The two continue to face off against each other, when Yuji enters a car and snatches a knife from inside just as Yuta tries to slash him but fails to and instead hits the knife. Yuji continues to slash at Yuta who tells Yuji that he's too focused on his katana and kicks Yuji. Yuta raises his sword and slashes Yuji's knife in half. Yuji is able to break Yuta's katana who then says this was never going to be easy. Just then, Rika manifests and asks what's going on while also holding Yuji in place. Yuta tells Rika that they're just playing before stabbing Yuji and apologizing.

Yuta drags Yuji's limp body to where Choso and Naoya are facing off and knocks Choso unconscious. He then comments on how Naoya looks injured and asks if he should use his reverse cursed technique to heal Naoya.

Elsewhere, Yuta watches over Yuji who suddenly wakes up as Yuta laughs and says what a relief. Yuji is confused by Yuta who explains that he needed to put an act on because Gojo sensei tasked him with watching over Yuji. Yuta also tells Yuji that in order for the jujutsu higherups to approve of Yuta being Yuji's executioner, he had to go into a Binding Vow with them to "kill" him. He apologizes as Yuji asks how he's still alive where Yuta reveals that he used a reverse cursed technique at the same time when his heart stopped. Yuta also reveals that the jujutsu higherups may figure out that Yuji isn't dead but for now, they considered Yuji's death sentence as completed. When Yuji asks why Yuta is doing all of this where he reveals that it is because Yuji is important to people who Yuta considers important. Yuta then tells Yuji about how he too once bore a power that he couldn't handle and that Yuji isn't to blame. Yuji says that Yuta doesn't understand and it isn't about his fault just as Megumi walks in.

Yuji is surprised by Megumi's appearance as he tells him to head back to Jujutsu High. Yuji suddenly tells Megumi to stop as if nothing ever happened. He says he killed people and because of himself lots of people died as Megumi angrily states its "our fault". Megumi tells Yuji to not be selfish and give up all alone. He also adds that they're jujutsu sorcerers and they aren't heroes fighting for justice. Yuta listens into Yuji and Megumi's conversation and thinks to himself about how Yuji resists but is unsure of whether or not he deserves to live. Megumi they must prove their worth of existence and don't have the luxury of thinking about themselves. Megumi also adds that they just have to save people. Yuji tells Megumi that as long as he's around, he will suffer. Megumi tells Yuji to start off by saving him and reveals that Noritoshi Kamo has started a culling game for those involved with jujutsu. He also says that Tsumiki is involed in this and he needs Yuji's strength.
