When Yuji, Megumi, and Gojo arrive, Gojo wakes up and sends them to were Utahime is at. 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.

When they reach the location that Kokichi is suppose to be at, they break in and find that Kokichi is at another location.

At the location that Kokichi is really at, 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 restrictions. As Mahito suggest 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 Kokichi. Kokichi tells them to just hurry up and heal him, which Mahito says to not blame him if he turns Kokichi into a caterpillar. Geto tells Mahito that they don't know what would happen if they break the vow they made with Kokichi, which Mahito agrees to heal Kokichi. Mahito then uses his Idle Transfiguration technique on Kokichi and completely heals his body. Mahito comments about how Kokichi 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. Geto asks if he should help him but Mahito replies that Kokichi is his toy. As Kokichi sends his puppets at Mahito, Mahito easily destroys them all. Mahito then notices that Kokichi is gone and comments about how he wanted to fight instead of going hunting.

Mahito then figures that Kokichi is piloting the puppet from its head. Inside the cockpit, Kokichi notices that a screen if blocking him from contacting Gojo. Kokichi thinks about how he will have to get in contract with Gojo. Kokichi thinks about how he will have to exorcise Mahito first and looks at Geto, which Geto says to not mind him. Kokichi then thinks about how he is currently at a disadvantage and that he can't be frugal with the cursed energy that he has saved up while also thinking about Miwa.

Kokichi fires a Ultra Cannon blast at Mahito, but Mahito heals himself and runs. As Mahito wonders what Kokichi is planning, which Kokichi thinks about how Mahito should know that Mechamaru's attack won't work on Mahito. As Kokichi attacks Mahito again, Mahito easily dodges it and turns into a fish while diving into the water. Kokichi attacks with a Miracle Cannon technique, but Mahito dodges it and grabs a hold of Mechamaru. Mahito thinks about how Kokichi doesn't care about his attacks and will be on the offensive, while Kokichi thinks about how he will use his secret weapon. As Mahito lands a blow on Mechamaru, Kokichi thinks about how Mahito will break the armor if he is not careful while loading his secret weapon. Mahito thinks about how he has to finish the fight quickly since he only has four chances with his secret weapon. Kokichi manages to blow off Mahito's arm with his secret weapon, much to Mahito's 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 watching the fight, he thinks about how Kokichi's countermeasures are working on Mahito. As Kokichi attacking with his Vision Viola technique, Mahito easily dodges the attack. As Mahito thinks about which techniques have an effect on his soul, Kokichi goes to attack Mahito. As Mahito tries to get away from Kokichi, Kokichi manages to land a blow. As Kokichi loads his secret weapon again, Kokichi thinks about how he can win this fight and join his friends.

Suddenly Mahito activates his Domain Expansion "Mahayana Prison" and says that he has won. Mahito then uses his Idle Mutation technique on Kokichi and the Mechamaru falls over. Mahito turns away from the Mechamaru and explains how Kokichi had lost the fight. Suddenly Mahito is pierced by the Mechamaru, much to his surprise. Kokichi thinks about how his secret weapon is a technique that allows him to create a territory that will protect him from others cursed energy. Kokichi then uses his secret weapon to blow up Mahito's body. As Mahito's Domain Expansion disappears, Kokichi yells out since he has won. Geto sees this and realizes that Kokichi secret weapon is "Simple Territory" technique and how this technique is capable of Neutralizes all other techniques. Kokichi then turns his attention to Geto and thinks about how he can win and will join the others. Suddenly Mahito breaks into the cockpit and charges toward Kokichi. Kokichi decides to use his last secret weapon by stabbing Mahito directly, and the two charge towards each other.

At the Kyoto school, Miwa is talking 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 Mechamaru is laying on the ground while Mahito and Geto are walking away. 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.

On October 31, a large screen was cast around Shibuya and multiple shamans were called to the seen. At the Shibuya station near exit 13, Nanami, Megumi, and Takuma are informed about how the screen is only capable of trapping humans. Suddenly Takuma starts to explains how a screen works to Megumi, which Megumi and Nanami state that Megumi already knows that stuff. 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, 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 what Gojo to handle everything alone with minimal damage, and how everyone else is just on standby. Panda comments about how the higher ups don't want to Shaman 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 their since he could feel that their are 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. As some wonder why they are in such a panic, one of them explains what they had saw at the train station. Suddenly Gojo arrives and starts to make his way towards the basement of the Hikarie ShinQ, while thinking about what they enemy is planning. Outside the screen at the Aoyama Cemetery, Yuji comments about how they should head into the screen to back up Gojo.

Suddenly the people surrounding them are forced towards them, which Hanami, Jogo, and Choso start to kill the people while making their way towards Gojo. As Choso distracts Gojo with a technique, Jogo and Hanami take this chance to attack Gojo with the Domain Amplification technique. Gojo quickly makes his escape and thinks about how Domain Amplification is capable of neutralizing his cursed ability. Jogo then 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. As Jogo runs away with Gojo right behind him, Hanami wonders what Gojo is planning since he had deactivated his Cursed ability. Hanami decides to uses his cursed ability and prepares to attack Gojo, which Jogo tells him to not deactivate his amplification. Gojo quickly grabs a hold of Hanami and rips the branches off of Hanami's head. Jogo then thinks about how strong Gojo is and that it is only because had his domain amplification activated that he was able to survive. Choso attacks Gojo, but Gojo easily blocks the attack. Gojo figures that Choso is one of the cursed womb death paintings and decides to not attack him since Choso is not proactive in the fight. Jogo and Hanami attack Gojo but Gojo easily blocks it and explains how he their technique is useless since he will just increase the strength of his ability. Gojo then use his ability to kill Hanami even when Jogo tries to stop Gojo by threatening to kill some humans. When Gojo finishes killing Hanami, he wonders who will be next.

The Meiji-Jingumae Station Incident
As Yuji, Mei Mei, and Ui Ui arrive at Meiji-jingumae station, they are informed that their are two screen surrounding the station. The manager tells them that their are mutated humans in between the screens, which Yuji thinks that this 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 is done, Mei Mei informed Yuji what she saw in the station. Yuji asks if Mahito is down their, which Mei Mei replies that she didn't see him but he must be in their since their are mutated humans in the station.

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 but notices an object and figures that that object is the source of the screen that he will have to break.

Suddenly the spirit comments about how the mutated humans that Mahito creates taste worse. Yuji starts to beat the spirit and comments about how he should not underestimate humans. The spirit says that Yuji is not smart and even doubt that Yuji can tell what kind of curse he is. Yuji replies that the spirit is a grasshopper cursed spirit, which the spirit thinks that Yuji is smart. As the spirit starts to attack Yuji, Yuji manages to dodges all the spirits attacks. As Yuji dodges the spirits attacks, Yuji thinks about how the spirit is a high level one. The spirit asks if Yuji is smart, which Yuji replies that smart people don't go around saying that they are smart which shocks the spirit. Yuji then starts to beat the spirit again, which the spirit wonders why he is the one that is getting hit even through he has more arms. As the spirit attack from a distance, but Yuji dodges and closes the distance. The spirit thinks about how he is smarter and attacks with its abdomen but Yuji easily dodges it and grabs it.

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 Gate's Boundary charm 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 Gate's Boundary
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.

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 Gate's Boundary.

A little while back Geto is planning mahjong with Mahito, Hanami, and Jogo, while explaining how the Prison Gate's Boundary is capable of sealing anything but the target has to stand still for a minute. Back in the present, Gojo sees the Prison Gate's Boundary open and starts to run when Geto shows up. As Gojo wonders why Geto is standing before him, a minute passes and the Prison Gate's Boundary 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.
