Shibuya Incident Arc

The Shibuya Incident is the eighth arc in Akutami Gege's Jujutsu Kaisen.

Investigating the Traitor
On October 19, 2018, Gojo is asleep and dreams about when he had first met Megumi and what they had discussed that day. When Yuji, Megumi, and Gojo arrive, Gojo wakes up and sends them to Utahime's location. Once the three meet up with Utahime, she tells them about the mole in the school and how they are going to investigate Kokichi Muta.

At the Kyoto School, Miwa meets with Mechamaru about the notebook that they have to turn in. Mechamaru tells her were he had left it and that he will be going to sleep for a bit. Once Mechamaru is asleep, Miwa wonders were the real Mechamaru is at. At another location, Utahime informs Nobara, Yuji, and Megumi about Kokichi's capabilities in using cursed energy. When they break into the room that Kokichi is held in, they find it empty, learning that he is at another location.

In a separate room entirely, Kokichi meets with Geto and Mahito. Kokichi comments about how he had thought that they had forgotten about him, which Geto replies that they would never do that since Kokichi knows the consequences of Cursed Restriction. As Mahito suggests they kill Kokichi since they have the information that they need, Geto tells him that they first have to heal Kokichi before they can kill him due to the terms of the Binding Vow between them. Mahito remarks that Kokichi should show some enthusiasm, but Kokichi replies that that comes after they settle their business.

Battle at the Dam
Mahito prepares to fight while Kokichi brings out multiple Mechamaru puppets. As Kokichi sends his puppets at Mahito, Mahito easily destroys them all. Upon noticing that Kokichi has disappeared, Mahito comments about how he wanted to fight instead of going hunting. As the floor under Mahito gives way, he heads outside of the dam only to stand facing a giant Mechamaru, revealed as Ultimate Mechamaru - Mode: Absolute. Mahito deduces that Kokichi is piloting the puppet from its head. Inside the cockpit, Kokichi notices that a screen manifested by Geto is blocking him from contacting Gojo. With a massive reservoir of cursed energy stored up from his time spent beneath Heavenly Restriction, Kokichi resolves to use that to defeat Mahito before going to get Gojo's assistance.

Kokichi fires Ultra Cannon at Mahito, but Mahito heals himself and runs. As Mahito wonders what Kokichi is planning, Kokichi realizes Mahito now knows he can't be hurt. As Kokichi attacks Mahito again, Mahito easily dodges it and transforms into a fish while diving into the water. Kokichi attacks with a Miracle Cannon technique, but Mahito avoids it and grabs a hold of Mechamaru. As Mahito strikes the cockpit in an attempt to break it, Kokichi loads up his secret technique, a capsule which he inserts into the cockpit. Hit in the wing by an exploding cannister, Mahito's arm is blown off by the weapon, much to his shock. Kokichi takes this chance to hit Mahito into the trees. As Mahito thinks about how that technique had destroyed his soul along with his arm, Kokichi continues his attack on Mahito. Mahito quickly makes his escape, which Kokichi notices Mahito's arm has regenerated. Kokichi figures that Mahito had kneaded his soul to make it seem that his arm has regenerated and that his secret weapon is working. As Geto watches the fight, he comments on the effectiveness of Kokichi's countermeasures and his strategy. Kokichi then unleashes Vision Viola, sending a barrage of lasers at Mahito which he dodges with ease. Kokichi manages to strike him down with a follow-up punch, however, and immediately deals another blow to Mahito upon his recovery. Loading up his secret weapon again, Ultimate Mechamaru gains a spike-like finger as Kokichi reminisces on his meeting up with his friends. This maneuver is cut short by Mahito activating his Domain Expansion, "Mahayana Prison".

With Kokichi now trapped in Mahito's Domain, Idle Transfiguration is activated, causing Ultimate Mechamaru to fall. Mahito turns away from the Mechamaru and explains how Kokichi had lost the fight, only to suddenly be pierced by him through the middle. Kokichi's secret weapon is revealed as Simple Domain - acquired from analyzing Miwa, he was able to protect himself from Mahito's domain on top of cancel Mahito's techniques. Activating Simple Domain once more, Kokichi seemingly blows up Mahito's body and kills him. As Mahito's Domain disappears, Kokichi yells out in triumph, with Geto expressing surprise at Kokichi's weapon. Kokichi then turns his attention to Geto, now prepared to attack him directly and take down the curtain. Suddenly Mahito, taking on a monstrous form, breaks into the cockpit and charges toward Kokichi. Kokichi decides to use his last secret weapon by stabbing Mahito directly for a fatal hit, and the two charge towards each other.

At the Kyoto school, Miwa talks to the sleeping Mechamaru about how she wishes to meet him in person since she feels that they have gotten closer during the baseball game.

Back at the Dam, the fallen Mechamaru is laying on the ground while Mahito and Geto make their departure. The two talk about how Mahito was able to avoid the technique and how they were able to see what the new screen is capable of.

In Shibuya on October 31
On October 31, a large screen was cast around Shibuya and multiple shamans were called to the scene. At the Shibuya station near exit 13, Nanami, Megumi, and Takuma are informed about how the screen is only capable of trapping civilians and that communication is blocked due to the curtain not allowing reception. Nanami then asks the manager where Gojo is at. At the Shibuya Mark City Restaurant Avenue Entrance, Akira informs Naobito, Maki, and Nobara about how the people inside the screen are saying to bring Satoru Gojo to Shibuya. Naobito comments about how someone told the people to say that and wonders if they can just break the screen. Akira says that breaking the screen would be tough and that it would be easier to just take out the caster. Maki says that they are here to help with that, to which Akira tells her that they are just here on standby. At the Jr Shibuya Station Shin Minami Entrance, Panda and Atsuya are talking about how the culprit behind the screen are most likely the same ones behind the Goodwill Event Incident. Atsuya then comments about how the higher ups want Gojo to handle everything alone with minimal damage, with everyone else on standby. Panda comments about how the higher ups don't want Sorcerers to be lost and wonders about the citizens. Atsuya says that he had looked in the screen a little while ago and that the citizens are just fine even through they are in a panic. Atsuya also comments about how he is not going back in there since he feels that there are likely multiple Special Grade Curses within the screen.

Inside of the screen, as multiple people are banging on the screen and asking for Gojo to be brought here, Gojo himself arrives and starts to make his way towards the basement of the Hikarie Shine. Outside the screen at the Aoyama Cemetery, Yuji comments about how they should head into the screen to back up Gojo. Mei Mei states that is why they are here, while Ui Ui, Mei Mei's brother, wonders why Yuji is to be Gojo's backup. Suddenly Mei Mei receives a call and is informed that another screen has suddenly appeared at Meiji Jingumae station. The three then head out towards the station.

Inside the station in Shibuya, Gojo arrives at the bottom floor and encounters Hanami, Jogo, and Choso. As Hanami blocks the exit, Gojo says that he won't be running away. All the gates at the station then open at once, causing civilians to fall into the middle of the tracks as Hanami, Jogo, and Choso start to slaughter them on their way towards Gojo. As Choso distracts Gojo, Jogo and Hanami take this chance to attack Gojo with their new technique - Domain Amplification. Gojo quickly makes his escape and thinks about how Domain Amplification is capable of neutralizing his Infinity. Jogo thinks back to when Geto talked with him about what Gojo is capable of and how they will counter Gojo's abilities. As Jogo comments about how Gojo is running away, Gojo takes off his blindfold and says that he is not running away and that he is going to take down Hanami first.

As Gojo gets close to Hanami and Jogo, the two attack but Gojo easily counters the two and wounds them. Jogo proceeds to run away with Gojo right behind him, and Hanami decides to use his technique to attack Gojo, realizing Gojo has deactivated Limitless. Gojo quickly grabs a hold of Hanami and rips the branches off of Hanami's head, realizing that you have to deactivate Domain Amplification in order to use cursed techniques. Choso attacks Gojo, but Gojo easily blocks the attack, deeming him a low priority and deciding to save him for later. Jogo and Hanami attack Gojo but Gojo easily blocks it and explains how their technique is useless since he will just increase the strength of his ability. Pouring all his cursed energy into his Limitless technique, Hanami is steadily pressed against the wall by Gojo's Infinity, even when Jogo tries to stop Gojo by threatening to kill some humans. When Gojo crushes Hanami against the wall, killing him, he coldly turns to Jogo.

The Meiji-Jingumae Station Incident
As Yuji, Mei Mei, and Ui Ui arrive at Meiji-jingumae station, they are informed that there are two screens surrounding the station. The manager tells them that there are mutated humans in between the screens, which Yuji thinks is Mahito's doing. After being informed about the situation, Mei Mei uses her ability on some crows to investigate the station. When Mei Mei finishes her investigation, she informs Yuji of what she saw in the station. Yuji asks if Mahito is down there, and Mei Mei replies that she didn't see him but he must be in their since their are mutated humans in the station. Mei Mei then says that they will split up and that they will meet up once they finish their tasks.

As Yuji enters another entrance, he comes across a cursed spirit. Yuji asks the spirit if Mahito is here, which the spirit says that Mahito is down below and that he is protecting the screen. As Yuji wonders if this spirit had put up the screen, he notices an object and realizes the spirit was only guarding an item that projects the screen.

Suddenly the spirit comments about how the mutated humans that Mahito creates taste worse, deciding to attack Yuji. As Yuji dodges the grasshopper spirit's attacks, Yuji thinks about how the spirit is a high level one. As the spirit attacks from a distance, Yuji dodges and closes the gap. The spirit begins an attack with its abdomen but Yuji easily dodges it and grabs it. Yuji then defeats the spirit and breaks the object that is creating the screen. At another entrance, Mei Mei and Ui Ui notices that the screen has been raised, and decides to meet up with Yuji and head towards basement 5. As the b5 station, Mahito notices that the grasshopper spirit has been done in and that he can't fight the shaman that did it since he has work to do.

Back at the Shibuya station, Jogo is running away from Gojo. Jogo manages to distract Gojo and launch an attack but Gojo blocks it and is forced to run away. Jogo thinks about how he can't let Hanami's death be in vain and will continue his hit and run tactic. Jogo tells Choso to help him out, which Choso attacks but it doesn't work. Gojo thinks about how the two spirits are attacking him and that it will be a matter of time until he can get to the two and exorcise them. Jogo thinks about how they can use the Prison Realm even through 20 minutes have already passed a while ago. A distance away, Geto and another spirit is watching the fight, and comments about how Gojo still has to get it more worked up.

At the Meiji-Jingumae station, Yuji meets up with Mei Mei and Ui Ui and they head towards the lower platform. While on their way to the platform, Mei Mei compliments Yuji capabilities and how Yuji can easily be a first grade shaman. Once they arrive at the platform, they notices that their is only one person their. Yuji asks the guy what had happened their, which the guy says that the rest were mutated and that he couldn't go because the train was full before mutating and dies. Yuji thinks about how this is the work of Mahito but realizes that the train full of Mutated humans head to the station that Gojo is at.

The Prison Realm
At the station the Gojo is fighting at, the train stops there which Jogo comments about Mahito is here. As the people start to head towards the train, but suddenly Mutated humans come out of the train and start to kill the people. Gojo sees this and wonders what the spirit are thinking. Mahito comes out of the train and meet up with Jogo. Mahito comments about how they should leave some humans alive and release them in a forest to hunt them. Jogo says that he will just burn the forest down, which Mahito replies that Hanami will get mad because of that. Jogo reveals that Hanami is dead, which Mahito is shocked by this.

As Gojo wonders what the spirits are planning, Mahito suddenly attack but Gojo easily blocks the attack. Gojo figures that Mahito is the one that attacked Yuji and Nanami and goes to attack but Mahito dodges it. Mahito comments about how find humans disgusting since their are some many of them, which at this point people start to pour into their location. Gojo figures that their are allies with the spirits above that are throwing people to their location. Mahito and Choso each use a technique to attack Gojo with, but Gojo easily blocks the attacks. Suddenly Jogo attacks which Gojo manages to grabs his arm, but Jogo severs his arm to get away. Mahito and Jogo thinks about how because of their current situation, Gojo won't activate his Domain Expansion. The spirit are shocked when Gojo starts to activate his Domain Expansion. Gojo only activates it for less then a second, which causes the spirits, mutated humans, and people to be stunned. As everyone is stunned, Gojo starts to kill all the mutated humans. Once his done, Gojo notices an object on the ground. At this point Geto activates the Prison Realm.

A little while back Geto is planning mahjong with Mahito, Hanami, and Jogo, while explaining how the Prison Realm is capable of sealing anything but the target has to stand still for a minute. Back in the present, Gojo sees the Prison Realm open and starts to run when Geto shows up. As Gojo wonders why Geto is standing before him, a minute passes and the Prison Realm starts to seal Gojo. Gojo notices that he had been trapped, and asks the person if front of him who he is. Geto says that he is Geto, but Gojo replies that he can tell that the person in front of him is not Geto. The person takes the top of his head off and reveals that he is capable of switch bodies, along with using the bodies natural abilities. The person tells Gojo that he will undo the seal after they are finished with their plans. Gojo says that they still have Yuta on their side, which the person replies that Yuta's power only came when he had detained his loved ones soul. The person then tell Gojo goodbye that they will meet again in the new world.

Down the train tunnel, Yuji, Mei Mei, and Ui Ui are heading to Gojo's location when something lands on Yuji's ear. Yuji is then contacted by Kokichi, who quickly explains that Gojo has been sealed.

Back at the station, the person tells Gojo that this is good night which Gojo replies that it is good night for him but its time to him to wake up. Gojo then asks Geto how long he is going to let someone else use his body, which Geto's arm suddenly grabs its neck. Mahito suddenly comes to their location after getting over being stunned, which the person explains to Mahito that his theory that the soul comes before the body is wrong. Mahito replies that it might be different for people since their Techniques are so different, which the person says that he like that techniques dictate their world. Gojo tells them to just get this over with, which the person says that he is correct and closes the Prison Realm and drops into his hand. Mahito comments about how they can't use it anymore, which the person says that only one person can be sealed within the object unless they kill themselves.

Back in the tunnel, Mei Mei asks why they should believe Kokichi. Kokichi replies that the proof is that he is their, and explains how he had died days before and that the one talking to them is nothing then a contingency plan that he had come up with just in cause something happened to him. Kokichi also says that he had elimination both Yuji and Mei Mei as being a mole within the school. Mei Mei asks why he eliminated them, which Kokichi says that Yuji has only been apart of the Jujutsu world for a few months and Mei Mei was sent to MejiJingu-Mae Station instead of staying at Shibuya. Mei Mei replies that she could just not be following orders, which Kokichi then asks why their are two Cursed Users following them. Mei Mei notices that their are two following them and asks Yuji if they are stronger then the curse that he had faced, which Yuji replies that the Cursed Users are stronger. Mei Mei wonders were the two were hiding and suggest they continue down the tunnel to were Gojo is at. Kokichi tells them that their are four screen in Shibuya, and that one of those screen block shamans from entering. Mei Mei tries to contact others, but notices that the screen is blocking them from making calls. Kokichi then suggests that Yuji should head back to Meijijingu-Mae station and head back to Shibuya from above ground. Kokichi tells Mei Mei to create a path for Yuji to get through the Cursed Users, which Mei Mei asks if Kokichi's bank account is not frozen. Kokichi finally tells them that they will have to put their lives on the line since they will need Gojo to save the Jujutsu world and Human Society. Ui Ui asks what he can do, Kokichi says that he can choose which he says that he will stay with his sister. As the Cursed Users show up, Mei Mei, Yuji, and Ui Ui prepare to fight.

Back at the Shibuya station, Choso and Jogo get over being stunned and meet up with the Geto impostor and Mahito. As the impostor is about to discuss what they are going to do need, when the Prison Realm suddenly forces it way to the ground. Inside of the object, Gojo comments about how time doesn't flow in the object and that he has messed up. Gojo then says that it is fine since he has faith in everyone.

Outside of the screen surrounding Shibuya, the groups that are on standby head inside the screen to rescue the citizens since curse spirits are attacking the citizens. At another location, a manager contact Akari and informs her that they to be in constant communications with the other managers when he is suddenly attacked by an enemy that had attacked during the cultural exchange. The enemy is told be someone to head around the screen and attack anyone who is wearing a suit, which the enemy agrees and announces that he will head inside the screen once he is done.

At the Shibuya Station, Mahito wonders what is going on which Geto explains how the sealing is complete but the Prison Realm will need time to process Gojo before they can move it. They notice one of Kokichi's devices and Mahito destroys it. At Yuji's location, Kokichi informs Yuji that the enemy can't move Gojo even through Gojo is sealed. Kokichi then proposes a plan were the shamans will attack all at once, when the screen surrounding Shibuya station comes down. Just before they enter the screen surrounding Shibuya, Kokichi inform Yuji that he can get in contact with Kiyotaka.

Operation: Rescue Satoru Gojo
Once Yuji enters the screen, he notices that spirits are attacking the citizens and quickly take care of them. After taking care of the spirits, Yuji quickly climbs up a building and yells out for Nanami. Yuji shouts that Gojo has been sealed, which Nanami informs Takuma and Megumi that they going to meet up with Yuji.

At the Shibuya Station, Impostor Geto and the Curse spirit hear what Yuji is shouting. The Impostor Geto informs the others that the shamans will increase in number and head this way. He also says that he will stay here and asks what they are going to do. Choso says that he will avenge his brother by kill Nobara and Yuji, and then head to the college to retrieve the rest of his brothers. Jogo tells Choso that they have to turn Yuji into Sukuna but Choso replies that he doesn't care. As Jogo gets angry, Mahito tells Jogo to calm down. Mahito then announces that he wants to kill Yuji too, and explains he had figured that Shaman and Curses are evenly matched after seeing Gojo in person. Mahito also says that they should kill Yuji since they don't need Sukuna since they can win even without Sukuna. Jogo continues to try to persuade Mahito that they need Sukuna, which Mahito says that he doesn't want to fight with Jogo on this matter. Mahito then says that he will make a deal with Jogo, in that if he finds Yuji fight then he will kill him or if Jogo finds Yuji first then he can offer Sukuna his finger in order to restore his power. Choso says that if he finds Yuji then he will kill him, which Mahito is glad that Choso is joining in. Mahito asks what the impostor Geto is going to do, which he replies that he has to keep an eye on the Prison Realm and that they can do whatever they want. As Jogo tells them that all the shamans are heading to their location, but the others ignore him and leave which Jogo follows after them. After the spirits leave, Mimiko and Nanako show up and tell the impostor to give back Geto's body. The impostor tells them that they should have done a binding vow with him and that they should leave or they will be killed by Geto's body. The girls say that the impostor will regret it, which the impostor sits down and comments about how he has forgotten what regret feels like.

Elsewhere Yuji is continuing shouting out Nanami's name until Nanami, Megumi, and Takuma show up. Kokichi then explains what had happened, and suggests what their should do next. After listening to everything, Nanami says that he will go meet up with Kiyotaka, which Yuji, Megumi, and Takuma deal with the screens that are blocking Shamans from entering. Nanami also tells Takuma that if they meet up with Atsuya and Naobito, to tell them what the situation is and that he is also in charge.

After Nanami leaves, Takuma tells Megumi and Yuji that their are two problems with Gojo disappearing. Takuma says that the first problem is that the Gojo family will fall from power since Gojo is the only member of that family. Takuma also says that Gojo has saved a lot of shamans with Yuji even being one of them. Takuma tells them that their will be those that will become a nuisance to the authorities and in the worst case they might be killed. Takuma then tells them that the second problem is that the balance of power will collapse. Takuma explains how their are those that have stayed in the shadow will make their move since Gojo is gone. Takuma also tells them that they will lose if they have to fight both Shamans and Spirits at the same time. After explaining this to them, the three head off to take down the barriers.

At another location, three shamans are protecting the objects that are creating the screen. One of them comments about how the intel of Gojo's sealing has been revealed, and wonders what would happen to this country now.

As Yuji tries to break through the next Screen, but Megumi realizes that the screen is to strong for them to break through it. As Megumi wonder how they can slip through the Screen, but Takuma explains how the screen basically works and that the castor is most likely inside the screen. Suddenly Takuma figures that the castor is mostly likely outside of the screen, since the screen would get stronger with the more risk to the castor their is. Megumi and Takuma then say that the castor would be at an obvious place, which Yuji figures out were they enemy might be at.

At the Shibuya Tower, the enemies are discuss if the Shaman might knew were they are at. They also discuss how it wouldn't matter since the bottom floors of the tower are swarming with Mutated Humans. Suddenly Megumi and Yuji shows up at the top of the tower, and manages to distract the enemies. Takuma takes this chance to break one of the Cursed Tools that is putting up the screen, but also realizes that one of the enemies had taken the other two Cursed Tools that are putting up the other screens. Megumi and Yuji quickly wrap the enemies with the Cursed Tools with a wire and tosses his off the tower. As Ogami has her grandson Awasaka fight Takuma, Takuma prepares to fight him and comments about how its time to show what he is capable of. As Megumi and Yuji find where the enemy has fallen, Megumi realizes that the enemy is still alive. As the Enemy gets up, Megumi and Yuji prepare to fight him.

As Takuma fights Awasaka and Ogami, he thinks back to when he told Nanami why he wanted Nanami to nominate him. Takuma uses his Cursed Technique to attack the two, which the two notice something about Takuma's technique. On the ground floor, Megumi and Yuji attack the enemy and notice that their attacks are doing nothing to him. Back at the top of the tower, Awasaka defends Ogami from Takuma's attacks while she chants. As Ogami finishes, Awasaka swallows something and starts to transform into Toji Zenin.
