Chapter Summaries

Seiya used four Shikigami to form his Simple Domain, the Four Flames Sacred Domain, and fought Ryomen Sukuna inside its blazing barrier. Sukuna endured the flames until Seiya ran out of Cursed Energy, but Gojo Satoru arrived before Sukuna could finish him, forcing Sukuna to return to Itadori's appearance.

• Seiya summoned the Tail Fire Tiger, Winged Fire Snake, Mouth Fire Monkey, and Chamber Fire Pig, then arranged them at the positions of the Four Symbols.

• Ijichi contacted Gojo Satoru, who quickly finished his assignment and rushed to the Juvenile Detention Center.
• Sukuna endured the domain's flames and kept fighting Seiya until Seiya's Cursed Energy was exhausted.
• As Sukuna reached to finish Seiya, he sensed Gojo's arrival, reverted to Itadori's appearance, and collapsed.

After waking from his battle with Ryomen Sukuna, Seiya learned that Itadori had died from the loss of his heart. Seiya rejected the news and rushed to the morgue, insisting Itadori could still be saved.

• Seiya asked where Itadori was, and Gojo Satoru told him that Itadori had died after Sukuna ripped out his heart.
• Seiya insisted Itadori was not completely dead and hurried toward the morgue to find him.

Seiya reasoned that Ryomen Sukuna had kept Itadori alive to preserve his Vessel, and Gojo found Itadori revived in the morgue. Gojo suspected Itadori had made a hidden agreement with Sukuna and decided to keep that concern from the jujutsu higher-ups while trusting Seiya with it.

• Seiya explained that Sukuna had a reason to keep Itadori alive, since losing his Vessel would threaten his awakened consciousness and Cursed Energy.

• Gojo chose not to report his suspicion to the hostile jujutsu higher-ups and considered Seiya a trusted, capable ally.

Gojo Satoru arranged special training for Itadori, Fushiguro Megumi, and Kugisaki, but found Seiya already had few weaknesses. Seiya explained why he could not yet perfect his Domain Expansion and asked to learn a difficult skill from Ieiri Shoko, leaving her curious about why Gojo had brought him.

• Gojo Satoru prepared individualized training for Itadori, Fushiguro Megumi, and Kugisaki ahead of the exchange event with Kyoto Prefectural Jujutsu High School.
• Gojo Satoru judged Seiya to be exceptionally capable and offered to teach him about domains, but Seiya declined because his Domain Expansion depended on summoning more Shikigami.

• Gojo Satoru warned Seiya that his requested training would be difficult and that Ieiri Shoko might refuse, but Seiya insisted he would try.
• Gojo Satoru brought Seiya to the infirmary, where Ieiri Shoko complained about his visit before letting them in and asking what trouble he had brought.

Seiya asked Ieiri Shoko to teach him the Reverse Cursed Technique and proposed a one-week trial as her assistant. Shoko agreed to guide him temporarily, expecting that the trial would convince him to give up.

• Gojo Satoru brought Seiya to see Ieiri Shoko and described him as an assistant for her workload.
• Seiya told Ieiri Shoko that he wanted to become her disciple and learn her Reverse Cursed Technique.
• Seiya explained that he wanted to learn healing because his fighting style relied on swordsmanship and hand-to-hand combat.

Tokyo and Kyoto Jujutsu High agreed to a seven-versus-six Sister School Exchange, with Tokyo required to exorcise thirty percent more Cursed Spirits to win. The late-arriving black-haired Tokyo student stunned the Kyoto group, and Todo recognized that he had approached without being detected.

• Utahime objected when Gojo revealed that Tokyo's exchange lineup consisted of first-years, and Todo said he was more interested in Okkotsu than the other Tokyo students.

• A cheerful black-haired boy arrived late and apologized, leaving Utahime, Gakuganji, Todo, and the others stunned.
• Mai dismissed the boy as ordinary, but Todo pointed out that she had not noticed him approach.

• Todo Aoi warned the Kyoto Branch School students that Seiya might have been able to ambush them before they noticed him, and he sensed that Seiya was formidable.

• Todo Aoi tossed Mechamaru aside and warned the Kyoto students not to interfere in his fight with Wenren Seiya.
• Seiya summoned Heart Moon Fox, Zhang Yue Lu, Net Moon Crow, and Wei Yue Yan, stunning the Kyoto students.

• Todo Aoi realized Seiya had turned the fight against the Kyoto team, while Iori Utahime and Gakuganji watched and recognized Seiya’s potential.

During the Sister School Exchange, Seiya’s talent and care for Ieiri Shoko convinced Gojo Satoru and Utahime that he had exceptional potential. An enemy barrier trapped the students and blocked Gojo, while Seiya reported a Special Grade Cursed Spirit inside and questioned whether the attack force was too small.

• Iori Utahime asked Gojo Satoru to let the Kyoto Branch School guide Seiya, but Gojo said Ieiri Shoko had already taken him as her disciple.
• Gojo explained that Seiya had learned the basics of the Reverse Cursed Technique in a week and had developed several Cursed Energy techniques while assisting Shoko.
• A massive Barrier Technique descended over the Sister School Exchange, trapping the students as Mahito and Kugisaki Nobara watched from the jujutsu higher-ups' building.
• Principal Yaga, Gakuganji, Gojo Satoru, and Iori Utahime hurried to the barrier, where they realized it had been strengthened to keep Gojo out.
• Seiya called Gojo and reported a white Special Grade Cursed Spirit with a branch growing from one eye, then questioned why the attackers had sent only one powerful curse.

Seiya warned Gojo Satoru that the attack on the students was a diversion and that the intruders’ real target was Jujutsu High’s Cursed Object vault. Gojo tried to reach it, but enemies blocked his path, including his dead former best friend Geto Suguru.

Seiya and the other students fought Hanami, who unleashed its Domain Expansion after learning that Gojo Satoru had engaged Jogo and Pseudo-Geto. The chapter left Seiya and Todo Aoi cutting through Hanami’s relentless tree roots while Itadori and Maki lay struck down inside the Domain.

• Maki and Panda were defeated by Hanami, leaving Itadori and Todo Aoi to battle the Special Grade Cursed Spirit.
• Todo Aoi and Itadori coordinated with Immoral Game, but Hanami learned from Jogo that their plan had been exposed and Gojo Satoru was confronting Jogo and Pseudo-Geto.
• Hanami expanded its Domain, Abundant Light Sea, and covered the students with flower seeds that devoured Cursed Energy when they tried to use it.
• Seiya, Itadori, Todo Aoi, and Maki attacked Hanami after avoiding or resisting the flower seeds.
• Hanami summoned guaranteed-hit tree roots that struck Itadori and Maki, while Seiya cut through the roots and Todo Aoi evaded them as more roots kept growing.

Seiya and Todo Aoi devised a two-stage attack against Hanami, using a thrown sword and Immoral Game to put Seiya above the Special Grade Cursed Spirit. Hanami recognized the trap but, seeing Seiya unarmed, met his descending punch with one of his own.

• Seiya and Todo Aoi realized Hanami's relentless plant attacks would wear them down, so Seiya risked injury to close the distance.
• Seiya threw his cursed tool Divine Blessing at Hanami, but Hanami blocked it with a wall of roots and sent the sword spinning away.

• Seiya plunged toward Hanami with a punch, revealing that the thrown sword had been a feint for their coordinated attack.
• Hanami assumed Seiya was helpless without his sword and punched back at him.

Seiya overwhelmed Hanami with his strength and fire, then used a vast Simple Domain to free the students and open an escape route. The students fled through the gap while Seiya remained to face Hanami.

• Hanami tried to drain Seiya's blood and Cursed Energy, but Seiya's punch twisted Hanami's arm and Agumon's Super Flame burned away the flesh buds.

After Seiya helped the students escape Hanami’s Domain Expansion and foiled the attack on Jujutsu High’s cursed object repository, the invasion ended with the students safe and the exchange event canceled. Gojo Satoru said Seiya’s achievements should earn him promotion to Grade 1, while Iori Utahime invited him to transfer to the Kyoto Branch School.

• Seiya and the others escaped Hanami’s domain, and Hanami retreated after receiving information while Seiya and Todo Aoi stopped the students from pursuing him.

Jujutsu Seiya complained that he needed stronger allies to survive Ryomen Sukuna, and two new Seiyas appeared in the Pure White Mystic Space. The group discovered that one came from the Naruto world and the other lived in an R18 world, though the latter had yet to make use of his setting.

• Leomon introduced Seiya as the Agumon of Sacred Dragon Mountain, and Seiya rejected responsibility for stopping Devimon or protecting other Digimon.

• The DigiDestined understood Leomon’s explanation but still wondered how Seiya could devolve on his own.

Seiya joined the DigiDestined on their way to Infinite Mountain to defeat Devimon, then battled Dark Gear-controlled Digimon alongside Leomon. As dark energy engulfed the summit and Black Gears flew toward it, the group faced a new development at Devimon’s stronghold.

• Leomon explained that the DigiDestined’s Digimon regressed because their borrowed power returned to the Digivice, though he could not explain Seiya’s ability to evolve and regress.
