Chapter Summaries

Suguru Geto entered Asama Ridge Mine to subdue the powerful cursed spirit inside, while Satoru Gojo waited outside. Geto defeated it with his Domain Expansion and Maximum: Uzumaki, but emerged exhausted and collapsed into Gojo’s arms.

• Geto reached the mine entrance with Rainbow Dragon and entered alone, while Gojo waited outside and gave him twenty minutes to return.
• Geto found the enormous rock cursed spirit deep inside and attacked it with Slit-Mouthed Woman and Rainbow Dragon.
• Geto activated Domain Expansion: [All Spirits Submit: Cursed Spirit Prison], but the rock cursed spirit countered with its own domain, [Netherworld Vein: Ten Thousand Bones Collapse].
• Geto used Forced Capture to discover the enemy domain’s core, then expanded his domain to push back the cursed spirit’s barrier.
• Geto used Maximum: Uzumaki to destroy the cursed spirit’s core, swallowed its Cursed Spirit Orb, and made the egg inside him grow.
• Geto returned to the entrance eighteen minutes and forty seconds later, where Gojo caught him as his legs gave out.

After being suspended from missions, Suguru Geto learned that the egg inside him was deforming his cursed energy core and agreed to Shoko Ieiri’s risky treatment. The first session partially restored the core and shrank the egg, leaving a second session scheduled for a week later.

• Masamichi Yaga told Suguru Geto that the Association had suspended him from missions and ordered him to rest.
• Yu Haibara shared rice balls with Suguru Geto and asked whether the egg inside him would hurt him.
• Shoko Ieiri gave Suguru Geto his examination report, explained that treatment had a thirty percent chance of success, and scheduled it for the next day.
• Shoko Ieiri used her cursed energy to push Suguru Geto’s deformed core toward its original shape while Suguru Geto calmed the resisting egg.
• Shoko Ieiri stopped the treatment after restoring about a third of the core and shrinking the egg from three and a half fists to three, then scheduled a second session for a week later.

Yuki May ordered Suguru Geto to report to Tokyo Headquarters for an evaluation, and he agreed to protect Jujutsu High from an Association inspection. After Shoko completed his final treatment, Geto left for Tokyo on January 31, carrying only Satoru Gojo’s knife.

• Yuki May told Suguru Geto to report to Tokyo Headquarters for a comprehensive evaluation by January 31 or face suspension and a security inspection of Jujutsu High.
• Geto agreed to attend despite Masamichi Yaga’s objections, saying he wanted to keep the Association from dragging others into his problems.
• Satoru Gojo told Geto to finish his final treatment before going to Tokyo, and Geto agreed.
• Shoko administered the last treatment, compressing the egg inside Geto to the size of two fists and relieving the pressure on his cursed energy core.
• Geto departed Jujutsu High for Tokyo Headquarters at five in the morning, carrying the knife Gojo had given him.

Suguru Geto underwent the Jujutsu Association’s assessment in Tokyo, where tests confirmed an unknown presence inside him, a 150 percent increase in cursed energy, and an open domain. The Association ordered him to remain at Jujutsu High and avoid missions while it reviewed the results, and he called Satoru Gojo before heading back.

• Suguru Geto told deputy director Yamamoto that something inside him absorbed and released cursed energy, though he did not know what it was.
• A physical examination showed that Suguru Geto’s cursed energy core had been compressed and that an unknown, two-fist-sized presence remained inside him.
• A cursed energy test found that Suguru Geto’s total cursed energy had increased by 150 percent since last August and had become more concentrated but unstable.
• Suguru Geto demonstrated his domain, and Yamamoto identified it as an open domain without a barrier.
• Yamamoto told Suguru Geto to stay at Jujutsu High and accept no missions until the Association sent its assessment results within two weeks.
• Suguru Geto called Satoru Gojo to report the test results and said he was returning.

After returning from Tokyo, Suguru Geto waited for the association’s evaluation while worrying about the egg changing him. Shoko and Satoru Gojo urged him not to face it alone, and Gojo reassured him that he would still be himself as long as the light in his eyes remained.

• Suguru Geto watched Yu Haibara and Kento Nanami spar, then told Haibara that the association would not lock him up.
• Shoko warned Suguru Geto that the egg was remodeling his cursed energy core and that the association might act later, and she urged him to share what he felt.
• Suguru Geto admitted to Shoko that he did not know how to describe the egg’s effects and promised to tell her once he understood them.
• Satoru Gojo asked Suguru Geto if he feared the egg hatching, and Suguru Geto admitted he feared no longer being himself.
• Satoru Gojo reassured Suguru Geto that the light in his eyes meant he would remain himself, whatever emerged from the egg.

Suguru Geto received a three-month suspension and found records of a past sorcerer whose cursed energy mutation resembled his own. As the egg continued to grow and an unfamiliar presence stirred in his consciousness, he concealed his abnormal sensations from the association and went to sleep.

• Suguru Geto learned the association had suspended him from missions for three months, and Yu Haibara promised to stay by him whatever happened.
• Suguru Geto searched Jujutsu High's archive for the Soul-Sealing Technique and found records of Special Grade Sorcerer Nakajima, whose growing inner presence had deformed his cursed energy core and led to his death.
• Suguru Geto worried that the association might eventually confine him as it had Nakajima and touched the knife Satoru Gojo had given him on his way back to the dorm.
• Satoru Gojo taught Suguru Geto to channel Rainbow Dragon's power directly, and Geto destroyed a target with little cursed energy.
• Suguru Geto wrote a weekly report claiming he had no abnormal sensations, though he could feel a voice-like presence within his consciousness as he drifted toward sleep.

During his suspension, Suguru Geto kept to a quiet routine while worrying about the deformation of his cursed energy core and the thing growing inside him. Records about Ichiro Nakajima deepened the parallel between their conditions, and Suguru ended the chapter choosing not to tell Masamichi Yaga what he had found.

• Suguru Geto asked Shoko whether Reverse Cursed Technique could repair his deformed cursed energy core, and she said it might take years or never recover.
• Suguru Geto told Shoko he had found a record of a Special Grade Sorcerer named Nakajima who had a growth inside him, was imprisoned by the Association, and died.
• Kento Nanami told Suguru Geto that Association officials had questioned Masamichi Yaga about Suguru’s movements and contact with the outside world.
• Suguru Geto asked Nanami not to tell Satoru Gojo about the Association’s inquiries, and Nanami agreed.
• Suguru Geto found an Association report blaming Nakajima’s death on spontaneous core collapse, a test report noting an unknown component in his cursed energy, and Nakajima’s letter describing the growth as a seed.
• Suguru Geto considered telling Masamichi Yaga about Nakajima’s case but left the archive and returned to his dorm without speaking to him.

During his suspension, Suguru Geto discovered Ichiro Nakajima’s journal, which described the echo’s nature and its consumption of memories. When the association’s examination triggered the echo to repel a probe and warn Geto not to let them in, he woke to find it had grown and gained a new layer of color.

• Suguru Geto found Ichiro Nakajima’s journal and learned that the echo was a remnant of a dead cursed spirit that consumed its host’s memories.
• Satoru Gojo told Suguru Geto that Sasaki, the association’s new investigator, was an ordinary person trained to sense changes in cursed energy.
• Sasaki questioned Suguru Geto about anomalous readings and requested a direct probe of his cursed energy core, which Geto accepted.
• During the examination, the echo absorbed the probe’s cursed energy, surged back through the machine, and left the technician injured before Geto lost consciousness.
• Suguru Geto woke six hours later and learned that Sasaki had asked whether the echo had consciousness.
• Suguru Geto silently asked the echo why it had protected him and sensed its answer: “Because you're mine.”

Suguru Geto made contact with the echo inside his body and learned it could feel pain and cold. As the Jujutsu Association imposed new monitoring, Masamichi Yaga defended Geto’s privacy, and Geto ended the chapter with the echo answering him by name.

• Suguru Geto heard the echo say it was cold and hurt, and Satoru Gojo recognized that it was conscious and could share Geto’s sensations.
• Suguru Geto received the Association’s warning against communicating with the echo, while Masamichi Yaga said Geto had the right to learn what was inside him.
• Three new observers arrived and demanded frequent monitoring and samples from Geto, but Masamichi Yaga refused to let them monitor him beyond the school infirmary’s records and weekly checkups.
• Suguru Geto reread Ichiro Nakajima’s journal and reached out to the echo, which answered that it was listening.
• Suguru Geto named the echo, and its pulse quickened in apparent happiness before settling as he promised to continue their conversation the next day.

Suguru Geto learned that Echo could perceive images beyond his own senses, including visions of the past and possible timelines. After Echo showed him a grieving Satoru Gojo amid ruins, Suguru comforted it, and its pulse gradually returned to normal.

• Echo showed Suguru Geto Ichiro Nakajima's room beneath the Old Library, first as it had been occupied and then tidied after his disappearance.
• Association observers Kiryū, Iguchi, and Tamura began checking Suguru Geto's cursed energy twice daily, while Yu Haibara worried they might be planning to imprison him.
• Echo showed Suguru a frightened version of Haibara standing alone in darkness, and Suguru remembered that Haibara had died in another timeline.
• At Suguru's checkup, Shoko recorded Echo's new ability to show images and advised him to observe them without overthinking.
• Echo showed Suguru an image of Shoko gazing at the sea, then showed Satoru Gojo standing amid ruins with bloodied hands and grief in his eyes.
• Suguru told Echo that Gojo's suffering was not its fault, and Echo's rapid pulsing slowly returned to its usual rhythm.

During a heavy snowfall, Suguru Geto reflected on Echo’s connection to the past and spoke with Satoru Gojo about what it might be. After Shoko found Echo had begun shrinking, Geto accepted it as part of himself and reassured it that it could stay.

• Suguru Geto visited the snow-covered cherry tree and saw Echo’s image of Ichiro Nakajima standing beneath it while already dying from depleted cursed energy.
• Satoru Gojo suggested that Echo might be a product of Suguru Geto’s changing cursed energy rather than residue left by cursed spirits, and said it had brought Geto closer to others.
• Shoko’s checkup showed that Echo had shrunk from the size of two fists to 1.8 fists, and she suggested it might be shrinking because it no longer needed to grow to prove it could exist.
• Suguru Geto recorded his thoughts in his diary, then told Echo it could stay and did not need to grow anymore.
• Echo pulsed calmly in response, and Suguru Geto felt it thank him.

Suguru Geto told Kiryū that he had been speaking with the echo, which had shrunk as his cursed energy core improved. The echo then showed him frightening images of ruins, an open door, and a lost Satoru Gojo, leaving Suguru Geto to comfort it and wonder whether it was his friend.

• Kiryū questioned Suguru Geto about the echo shrinking and his core recovering, and Suguru Geto admitted he had told the echo it could stay.
• Kiryū warned Suguru Geto to stop communicating with the echo and treat it as a foreign body to monitor.
• Before dawn, Suguru Geto experienced visions of a ruined city, a barred iron door opening onto a void, and a future-looking Satoru Gojo asking where he was.
• Suguru Geto found Satoru Gojo’s room empty and realized the echo was afraid the door would open and Satoru Gojo would not find him.
• Suguru Geto promised the echo he would stay and keep the door from opening, then asked whether it was his friend; the echo pulsed once.

Suguru Geto investigated the locked basement room and challenged the Association’s decision to place him under supervision. After he began reporting in, Satoru Gojo promised to help him leave Jujutsu High in five weeks.

• Suguru Geto went alone to the Old Library, considered opening the basement door, and concluded that Echo had made Ichiro Nakajima’s room appear as a void.
• Kiryū confronted Suguru Geto about visiting the basement and ordered him to report to the Reception Room three times a day under centralized supervision.
• Suguru Geto refused to report on Sunday morning until Kiryū, Iguchi, and Tamura came to his room, then went with them to the Reception Room.
• Suguru Geto wrote “I am not Ichiro Nakajima” on his record form and returned to the corridor.
• Satoru Gojo told Suguru Geto the supervision would likely end after his reassessment in five weeks and promised to show the Association what abnormal meant if it did not.
• Suguru Geto told Echo that he and Echo would leave Jujutsu High in five weeks.

Suguru Geto remained under strict supervision as Satoru Gojo and Shoko visited him and urged him not to isolate himself. As the echo inside him continued shrinking and showed him the iron door in the Old Library basement, Geto wondered whether he was choosing confinement or had become unable to leave it.

• Kiryū checked Suguru Geto three times a day while Iguchi and Tamura guarded the dorm, and Geto spent his days confined to the reception room and his dorm room.
• Satoru Gojo defied Kiryū’s orders to bring Geto cafeteria ramen, told him he was already involved, and asked whether Geto would enter the iron door if it opened.
• Geto told Satoru Gojo that the shrinking echo showed him an iron door and that it still spoke to him.
• Shoko visited Geto and explained that Ichiro Nakajima had stayed in the basement by choice, then urged Geto to return to the infirmary and stop locking himself away.
• Geto wrote in his diary that the echo had shown him Ichiro Nakajima’s hands, which seemed to be reaching for something, and wondered whether Ichiro had clung to the unopened door.

Suguru Geto’s movement restrictions ended early, and he resumed training and missions as Echo continued shrinking and adapting to his core. After a successful Grade 2 mission, Satoru Gojo and Shoko Ieiri suggested Echo was merging with him, while his next checkup showed his condition had improved further.

• Kiryū delivered the Association’s decision lifting Suguru Geto’s movement restrictions, and Suguru Geto reflected on what freedom meant in his diary.
• Kento Nanami gave Suguru Geto the next week’s mission schedule, and Suguru Geto chose to take a mission the following Monday.
• Suguru Geto subdued and absorbed a Grade 2 Cursed Spirit in Ichihara, while Echo accepted its cursed energy without growing.
• Satoru Gojo told Suguru Geto that Echo was adapting to him and said it would reveal what lay beyond the door when Suguru Geto was ready.
• Shoko Ieiri’s checkup showed Suguru Geto’s core deformation had fallen to very slight, and she said the Association might end his suspension early.

Suguru Geto investigated an abandoned hospital and met Tokieda, who claimed to carry the other half of echo and demanded that the halves reunite. Geto returned to Jujutsu High uncertain about what reunion would mean, but echo’s pulse told him it wanted to live.

• Suguru Geto sent cursed spirits to scout the abandoned hospital and found a strange, unusually clean cursed energy environment.
• Tokieda revealed that he carried the other half of echo and said the two halves were disappearing unless they reunited.
• Suguru Geto and Tokieda fought, and Tokieda used his palm’s black mark to try to pull echo from Geto.
• Tokieda left Geto to decide whether to reunite the halves, warning that time was running out.
• Suguru Geto returned to Jujutsu High and asked echo if it wanted to reunite; echo pulsed to say it wanted to live.

Suguru Geto investigated the disappearance of four jujutsu sorcerers in Chiba and found clues at Kumano Shrine, including Kazuya Yamada’s identification plate and a cursed-energy-tainted doll. He realized the traces matched those Tokieda had left at the hospital, and resolved to find the person responsible.

• Masamichi Yaga assigned Suguru Geto to investigate four missing Grade 2 jujutsu sorcerers in the Kanto region.
• Suguru Geto searched the quiet Chiba town and found footprints that vanished inside Kumano Shrine’s worship hall.
• Suguru Geto discovered Kazuya Yamada’s scorched identification plate and a strange rag doll hidden beneath a stone lantern.
• Masamichi Yaga sensed faint human cursed energy on the doll and advised Suguru Geto to have Shoko examine it.
• Suguru Geto recognized the doll’s traces as the same kind Tokieda had left at the hospital and decided to search for the person who took the sorcerers.

Suguru Geto learned that the doll carried a trace from a dead cursed spirit and belonged to the Kumano Society, a group of curse users tied to the missing sorcerers. The priest identified the missing Mayu Sato and revealed that Tokieda had once belonged to the Society and was hunting it after it killed his younger brother.

• Shoko told Suguru Geto that the doll held a fragmented trace from the same source as Echo and that the hair sewn into it belonged to a jujutsu sorcerer.
• Suguru Geto found several Kumano Shrines marked across Kanto and visited the active shrine in Kawagoe to investigate the doll’s name.
• The priest told Suguru Geto that the doll belonged to the Kumano Society, an organization of curse users that carried out forbidden activities.
• The priest identified Mayu Sato as a sorcerer who had disappeared in Kawagoe after asking about a similar doll.
• The priest told Suguru Geto that Tokieda had left the Kumano Society and was tracking it because its members had killed his younger brother.
• Suguru Geto realized Tokieda had been pursuing the Society when they met, and that their encounter at the abandoned hospital had been incidental.

Suguru Geto followed a hidden message to an abandoned mine in Ome, where Hazuki, president of the Kumano Society, told him that Tokieda had taken the missing sorcerers to sustain the echo inside himself. Geto left the mine and asked Satoru Gojo to investigate Hazuki, while Tokieda remained on the way to claim the last portion of cursed energy.

• Suguru Geto found a hidden note in the rag doll directing him to a meeting place at an abandoned mine in Ome.
• Suguru Geto traveled alone to the mine and discovered Hazuki waiting among a collection of identical dolls.
• Hazuki told Suguru Geto that Tokieda had taken the four missing sorcerers and was using their cursed energy to slow the echo inside himself from disappearing.
• Hazuki said Tokieda had gone to find the last person with cursed energy and would come to Suguru Geto once he had obtained it.
• Suguru Geto left the mine and called Satoru Gojo, asking him to investigate Hazuki and the Kumano Society.

After learning that Tokieda was connected to the Kumano Society and that his brother died from cursed energy core collapse, Suguru Geto set out with Satoru Gojo to investigate. In the abandoned mine, they found proof that seven echo fragments were scattered across Kanto, and Geto chose Tokyo as their next destination.

• Satoru Gojo told Suguru Geto that Tokieda had once belonged to the Kumano Society and that his brother Shigure had died from cursed energy core collapse.
• Geto decided to find Tokieda before he gathered the cursed energy of four jujutsu sorcerers, and Gojo agreed to accompany him.
• Geto and Gojo returned to the abandoned mine in Ome, where they found that Hazuki and the embroidered dolls were gone.
• Gojo found scratches on a stone wall like those in the Old Library, and Geto felt the echo throb as he touched them.
• Geto opened a hidden box and read that seven echo fragments had remained after Ichiro Nakajima's death, scattered across Tokyo, Saitama, Chiba, and Kanagawa.
• Geto followed the echo's guidance and chose Tokyo as their next destination.
