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, where 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 Tokyo 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 involved in this and he needs Yuji's strength.

Culling Game Arc
Yuji talks to Yuta about how Sukuna is plotting something for Megumi. He mentions that Sukuna most likely took over his body in Shibuya because he ate all ten in one go and also includes that he has already eaten fifteen fingers. Yuji then says he doubts Sukuna would be able to take over his body after he's eaten the rest of the fingers, however, if Sukuna is able to Yuji asks for Yuta to kill him as he believes he's able to do that. Yuta says he'll do what he can do if that ever happens. While Megumi is talking about the Prison Realm and Noritoshi Kamo's motives, Yuta comments on how the problem is Tengen's concealing barrier. When Choso suddenly appears, Yuta is surprised to see Choso and wonders if he was listening.

Afterwards, Yuta along with Yuji, Megumi and Choso all head to Tokyo Jujutsu High where Yuta notices Maki's bandages and asks her if it's okay for her to move around who replies that it's fine. Yuta listens to Yuki as she tells him that even a reversed cursed technique can't get rid of the burn scars Maki now has and includes the reason behind why Maki is still alive. It is because of her in born toughness that saved her from death. Yuta listens to Choso as he explains about his connections with the Death Painting Wombs being held at the warehouse should be able to provide some guidance. Yuta goes to the elevator with the others where they go to where Master Tengen resides. When Yuji asks about the blood stains and what happened there, Yuki explains how it all started 11 years ago when everything started to get distorted which leaves Yuta confused. The group enters an area where they find is completely empty, Yuta tells them to just head back because Tsumiki doesn't have enough time. Just then Master Tengen appears and asks why they're leaving so soon before greeting them.

Yuki confronts Tengen and asks why they're not greeting her which Yuta is surprised to see Tengen. Tengen tells them that they were afraid they were aligned with Kenjaku, which Yuki wonders who they are. Tengen reveals that Kenjaku is the sorcerer who was once Noritoshi Kamo but now is inhabiting Suguru Geto's body. Upon having Yuji suddenly ask why Master Tengen looks the way they do, Megumi thinks to himself about how much guts he has for cutting into an important discussion. Tengen reveals that although they are immortal, they are not immune to aging, which surprises Yuji. It was 11 years ago where they failed to merge with the Star Plasma Vessel that their age accelerated and self awareness as an individual diminished. Yuta and Megumi interrupts the conversation asking about Kenjaku's objectives and how to open the Prison Realm. Tengen tells them that they wished they could simply say yes but there is one condition: Yuki Tsukumo, Yuta Okkotsu and or Choso are to remain as his two guards. Yuta is confused and asks why they need guards despite them being immortal. Maki adds on wondering if it's because of the seal.

Yuki objects to this as Tengen tells them that Kenjaku's objective is to force the evolution of all humankind throughout Japan. Megumi tells them that they are aware of this but asks what exactly does Kenjaku intend on doing. Tengen explains how Kenjaku lacks the cursed energy to do so. Someone asks why Kenjaku didn't use their barrier at that time in Japan into sorcerers via Idle Transfiguration. Tengen reveals that the method Kenjaku has chosen is to merge humankind with themselves. Yuji is shocked by this and asks if it's even possible, where Tengen confirmed. Choso asks how can they merge with multiple people even though they're only a single person. Tengen confirms that they are indeed one person but due to them having evolved over the past 11 years, it would not be impossible for them to merge with someone other than a Star Plasma Vessel.

Tengen tells them that a human who merges with themselves transforms into something greater than a sorcerer as a new being that is both there and also not there. Tengen explains that they possess barrier techniques which enable them to maintain their current form and self control even after evolving. They add on that if humankind evolves and only one person rages out, the world will end. Yuki asks them why who says that the impurities of a hundred million people would flood the world, which what happened to Tokyo would happen to the entire world as well. They add that there are no boundaries between individuals so evil would instantly spread. When Maki asks why they refuse to merge, Tengen says that is the problem. Yuji asks Tengen why Kenjaku would do this who is unsure why because they cannot read human hearts.

Tengen tells the group that now that they've evolved, they are more cursed spirit than human which makes them a target for cursed spirit manipulation, shocking everyone. Tengen tells them that considering Kenjaku's ability as a sorcerer he might be able to seize them when they encounter each other. They add on that this is the reason why their main body is rejecting everything at the Tombs of the Star Corridor. Yuta then asks if that's the reason why they want guards which they confirms. Tengen tells them that Kenjaku is the second most powerful barrier user behind themselves and adds that they are unsure when he will undo the seal on the tombs. Yuki asks why now and adds on that Kenjaku prevented a merging with a Star Plasma Vessel, wants to consume and control them through curse manipulation and also was apparently was involved with Sukuna so he has been a sorcerer for over 1,000 years. Tengen says that themselves, the Star Plasma Vessel and the Six Eyes are all connected by faith.

Tengen reveals that Kenjaku lost twice to a sorcerer with the Six Eyes and the second time he took no chances and killed both the Star Plasma Vessel and the Six Eyes less than a month after they were born. On the day of the merging, both the Six Eyes and the Star Plasma Vessel appeared. Which Kenjaku switched to sealing instead eradicating the Six Eyes and thus began searching for the Prison Realm because two bearers of the Six Eyes cannot appear at the same time. However, the unexpected happened 11 years ago when Toji Zenin intervened. Megumi is confused by this but doesn't say anything. Tengen tells them that he was physically gifted through a Heavenly Restriction and was an anomaly who had zero cursed energy and destroyed their destiny. Then came a boy with curse manipulation, where all the pieces suddenly came together other than for the Prison Realm which fell into his grasp six years ago.

Megumi then asks why the culling game is happening, Tengen explains the culling game uses the participants and the boundaries binding barriers in a ritual that conveys to the human beings of this country to the other side. And with that, Kenjaku will begin the merging with themselves, however, to preform the ritual, he has undertaken certain binding vows. They add on that one stipulates that he isn't the game master and this game doesn't work in their favor because even if Kenjaku is killed, the culling game will continue until all participants are either dead or the players refuse to participate and die. Megumi is upset from learning of this. Yuta concludes that they have no other choice but to participate and add a rule that allows Tsumiki and other unwilling participants to safely get out. Megumi adds that they also should free Gojo sensei because he would be able to settle everything on his own. Yuji looks over at Master Tengen and asks for them to tell them but they say to first decide who should remain as guards.

Much to the surprise of both Yuji and Megumi, Yuki and Choso step up for that position. Choso tells Yuji he will absolutely need either Okkotsu or Yuki's cooperation especially if Kenjaku comes for Tengen. Tengen thanks the group before pulling out a box that is the "back" of the Prison Realm. Megumi is shocked to hear that there is a "back" for for Prison Realm. Tengen explains that before Kenjaku found the Prison Realm, it was outside of their barrier who believes it was overseas and reveals that by sealing the rear gate, they were hiding the existence of the "front" but it was useless. Yuji asks if it's like a back gate which Tengen confirms it is. Tengen tells them that Gojo is sealed inside of the rear gate as well and that the authority of opening the gate rests with Kenjaku as he is the bearer point of the "front". They add on that to break it open, they will need the Inverted Spear of Heaven that nullifies cursed techniques and or the Black Rope that disrupts and cancels cursed techniques effects.

Yuji and Megumi are shocked because Gojo either sealed and or destroyed it 11 years ago but Yuta tells them that he along with Miguel searched for it in Africa but to no avail. Yuki asks Tengen if there's another way who confirms there is. Tengen reveals that among the players participating in the culling game, there is a sorcerer from 1,000 years ago who calls herself, an angel and that her cursed technique can extinguish any cursed technique.
