Chapter Summaries

Sosuke Aizen confronted Uchiha Madara in the God Tree Space, but Otsutsuki Urashiki revealed that Aizen’s future would consume the world and tried to send him away. Aizen instead used Urashiki’s time-space device to travel to another world, leaving Kakashi and Senju Tobirama in charge of Las Noches until his return.

• Sosuke Aizen broke the Divine Tree's Space-Time Barrier, stopped its Chakra network, and confronted Uchiha Madara while asking him to release Obito and Rin with their consent.
• Uchiha Madara asked Aizen to send Kakashi Hatake of Konoha home, and Aizen opened a Garganta for him.
• Otsutsuki Urashiki appeared and activated the damaged Plow with Kakashi's Bankai, attempting to send Aizen to another world after warning that Aizen's future would bring endless suffering to all life.
• Aizen recognized the light curtain as a cavity and poured his Chakra into it, helping repair the passage instead of resisting it.
• Aizen told Kakashi to have Senju Tobirama lead Las Noches with him until Aizen returned, then vanished through the passage with Hatake Kakashi's Bankai.

Kakashi woke at home believing his encounter with another world had been a dream, only to find Sosuke Aizen there and learn it had really happened. Aizen began recounting the radically different history of his world, leaving Kakashi stunned and ready to take notes.

• Kakashi woke in his Konoha home, recalled his dream of fighting alongside his younger self, and tried to dismiss it as a nightmare.
• Kakashi found Sosuke Aizen calmly reading a newspaper in his living room and realized Aizen was truly there.
• Aizen explained that Kakashi had traveled to another universe and returned after the Otsutsuki used Plow to imprison them and cast them into other worlds.
• Kakashi agreed to exchange verifiable information with Aizen and asked him to explain the history of his world.
• Aizen described leaving Konoha with Hiruzen Sarutobi and Shimura Danzō to establish rival organizations, while the Ninja villages formed opposing alliances; Kakashi was left astonished.

Kakashi told Sosuke Aizen about the bleak history of his world and asked what Aizen intended to do about Konoha. Aizen requested access to Konoha’s records about Orphanage No. 3, but Might Guy interrupted their conversation at dawn.

• Kakashi read about the vastly advanced alternate world and listened as Aizen explained his vision for Las Noches and the Borderless Army.
• Aizen said he might act against anyone who obstructed his ideals and admitted he could not promise to spare Konoha or Kakashi.
• Aizen asked to study Kakashi, learn about this world’s technology, and visit the major Ninja Villages, so Kakashi recounted his timeline and the deaths and wars it had brought.
• Kakashi described Team 7’s fate, and Aizen noted that Minato and Kushina had died, the Uchiha Clan had been exterminated, and the Hyuga Clan’s Caged Bird still remained.
• Aizen asked Kakashi to investigate Konoha’s records about Orphanage No. 3, where Aizen had been found, but Might Guy arrived to challenge Kakashi as dawn approached.

Kakashi brought Sosuke Aizen to meet Might Guy, whose fervent ideas about youth quickly captivated Aizen. Aizen decided to remain in Konoha, report to the Hokage, and teach Guy, while Kakashi resigned himself to the unlikely pairing.

• Kakashi opened his home to find Might Guy waiting to challenge him to a spar.
• Aizen healed Kakashi’s injuries and set up a Chakra connection that could shut off his Mangekyō Sharingan when unused.
• Aizen asked Guy about the Eight Gates Formation and offered to share training research involving Guy’s father.
• Guy explained that youth meant constantly pushing forward, and Aizen enthusiastically interpreted it as a drive to challenge limits.
• Aizen decided to stay in Konoha, accompany Kakashi to report to the Hokage, and teach Guy afterward.

Might Guy reported Sosuke Aizen and Kakashi to Hokage Tsunade, who confronted Aizen at the Hokage Building. Aizen offered a bargain, but Tsunade ordered his capture, and he answered with a devastating Kido spell.

• Might Guy left Aizen and Kakashi to train, then reported them to Tsunade at the Hokage Building.
• As Aizen and Kakashi walked through Konoha, Aizen praised Might Guy's determination and spoke about pursuing one's own convictions.
• Tsunade confronted Aizen with Konoha's Ninja and demanded to know who he was, while Aizen claimed he had once been a Konoha Ninja from another world.
• Aizen offered to grant a wish, even to revive the dead, in exchange for access to Konoha's intelligence network and research materials.
• Tsunade refused the bargain and ordered the Ninja to activate the Four Violet Flames Formation.
• Aizen warned Tsunade to activate the Hundred Healings Technique, then unleashed Way of Destruction Number Thirty-Three: Cinder-fall, sending a pillar of fire skyward.

Sosuke Aizen overwhelmed Konoha’s forces to demonstrate his strength and insisted he wanted to negotiate rather than become their enemy. After binding the gathered Ninjas, he revealed that he knew Tsunade as Captain Tsunade Senju of Konoha’s 13th Guard Division, Fourth Division, and began explaining why he had sought dialogue.

• Aizen broke through the Four Violet Flames Formation, engulfed Konoha’s plaza in blue fire, and left Tsunade relying on Creation Rebirth to survive.
• Aizen stopped a Konoha Ninja’s attack with a glance, while Might Guy opened the Gate of View and struck him with Reverse Lotus without causing harm.
• Aizen explained that ordinary ninjutsu and taijutsu could not hurt him, then absorbed Chakra from the air and nearby Ninjas.
• Guy prepared to open the Gate of Death, but Aizen used Bakudō Number One, Seki to pin every Konoha Ninja present to the ground.
• Aizen explained how Seki worked and told Tsunade that he knew her as Captain Tsunade Senju of Konoha’s 13th Guard Division, Fourth Division.

Sosuke Aizen subdued Konoha’s Ninja, explained that he had come to understand the differences between their world and his, and transported them to the Unseen Court, a hidden world linked to Konoha’s shadows. After ordering the injured Ninja to recover, Tsunade found evidence of an alternate future in the Fourth Division captain’s office, including a research document bearing her name and Dan Katō’s.

• Sosuke Aizen told Tsunade that he came from a different past and had once lived in Konoha, and he said he wanted to speak with Kakashi normally.
• Sosuke Aizen used his sword to reveal the Unseen Court, a palace complex he said was connected to Konoha’s shadows, and released the Ninja from their restraints.
• Sosuke Aizen offered the Ninja places to recover, Chakra hot springs, and uniforms, then disappeared into the Sixth Division captain’s office.
• Tsunade ordered the Ninja to form groups of three, recover in the division barracks, and await her assembly order.
• Tsunade searched the Fourth Division captain’s office and found a future research document on the Improved Theory of the Hundred Healings Technique, listing herself, Orochimaru, and Dan Katō as co-authors.

Tsunade studied documents from another world describing a terrifying new version of the Hundred Healings Technique and found comfort in evidence that she could have lived a happier life. Across Soul Society, the Ninja searched for traces of their alternate-world lives while Aizen waited in his office for them to arrive.

• Tsunade soaked in the captain's office hot spring while reading records about version 7.4 of the Hundred Healings Technique and its possible path to immortality.
• Tsunade dressed in a captain's outfit that fit her perfectly, then chose to search the office for traces of her alternate-world life instead of confronting Aizen immediately.
• Kakashi Hatake and Might Duy explored the 11th Division barracks and found a sword technique booklet credited to Kakashi's father, Hatake Sakumo.
• Kakashi and Might Duy agreed to keep exploring Soul Society for intelligence, while Might Duy celebrated finding signs of his father's youthful presence there.
• Aizen waited in the Sixth Division captain's office, wondering why the Ninja had not come to see him.

Tsunade and the Konoha Ninja negotiated a cooperation deal with Sosuke Aizen after exploring the Unseen Court and examining its records and technologies. They returned to Konoha with the agreement settled, while Tsunade briefly glimpsed a figure resembling Dan Katō in the shadows.

• The Ninja arrived at Aizen’s quarters after spending hours exploring Soul Society and examining its records and artifacts.
• Aizen offered Konoha theories and techniques in exchange for access to its intelligence system, research summaries, and a designated area for his experiments.
• Tsunade secured conditions against ecosystem-damaging experiments and required Aizen to teach Konoha disciples or let them assist with his research.
• Tsunade and Aizen finalized their agreements, and she led the Ninja out of the Unseen Court and back to Konoha.
• While leaving, Tsunade glimpsed a weary figure resembling Dan Katō, then set aside her questions and returned her attention to Konoha’s development.

After Sosuke Aizen left, the balance holding the Ninja World together weakened and the threat of a major war grew. Hiruzen Sarutobi tried to rally Konoha’s Soul Reaper captains to prevent war, but their indifference left him planning to speak with Minato instead.

• Dan Katō told Tsunade he had mistaken a vision of her for her leaving, and she urged him to keep working despite the strain on the Covert Operations Unit.
• Aizen’s departure fractured the balance among the world’s powers as small nations and ambitious factions prepared for conflict.
• Hiruzen Sarutobi called a captains’ meeting and declared that Konoha should contain the growing threat of war, even through covert measures.
• Kagami Uchiha supported Hiruzen and proposed that Konoha claim the cause of peace and use networked military exercises to show people the reality of war.
• The captains showed little interest in intervening, and Hiruzen ended the meeting, saying he would discuss peace with Minato.

Minato Namikaze worried that the 13th Guard Division and other Soul Reaper organizations were drifting away from Konoha after Sosuke Aizen’s departure, while political tensions across the Ninja World threatened to erupt into war. He resolved to contain the turmoil to protect Konoha’s interests, wondering whether Aizen had foreseen the crisis.

• Minato learned that Hiruzen Sarutobi had convened a captains’ meeting without his approval, deepening the divide between Konoha and the 13th Guard Division.
• Minato told Kushina that the Soul Reapers were becoming detached from ordinary Ninja and that three organizations had already declared their independence from their villages.
• Minato described how the Daimyo demanded an attack on Las Noches while the great nations and villages grew increasingly restless, and he feared the conflicts could trigger a world war.
• Kushina urged Minato not to assume the 13th Division would abandon Konoha, and Minato recalled Aizen’s warning that ambition expanded with ability.
• Minato concluded that Konoha had to preserve the peaceful system for its own interests and wondered whether Aizen had anticipated the turmoil.

Sosuke Aizen examined evidence that he had no counterpart or roots in this world and considered how Chakra resonance might connect parallel worlds. He then welcomed Sakura Haruno, Ino Yamanaka, Shino Aburame, and Shikamaru Nara as students sent by Tsunade, leaving them to begin their studies under his guidance.

• Aizen concluded that Kakashi Hatake's summoning and their shared Chakra could let him detect and interact with other worlds, though he had no clear route back to his original world.
• Aizen reviewed Konoha records and found that neither the orphanage nor the civilian named Ishige from his memories had existed in this world.
• Aizen decided to fulfill his exchange with Tsunade by teaching four selected Konoha youths new techniques, while furthering his own research into resonance.
• Sakura Haruno arrived first and introduced herself as a student sent by Tsunade, then led Aizen to Ino Yamanaka, Shino Aburame, and Shikamaru Nara.
• Aizen welcomed the four students and urged them to share their thoughts; he told Shikamaru that clever people could become foolish when their reasoning led them to predictable conclusions.

Sosuke Aizen gave Shikamaru Nara, Shino Aburame, Ino Yamanaka, and Sakura Haruno an overwhelming curriculum supported by pills and talismans that let them study almost nonstop. As Aizen assigned each of them research suited to their ambitions, the others embraced the work while Shikamaru remained horrified by the prospect.

• Sosuke Aizen presented the four young ninjas with an enormous index of Chakra theories and explained pills and talismans that could sustain their bodies and focus for a month.
• Shino Aburame asked whether the research could help him breed new insects, and Aizen directed him to biology materials and offered access to testing grounds and supplies.
• Ino Yamanaka asked about flower-related Chakra research, and Aizen pointed her toward Wood Style and life-energy studies that could lead to flower-based ninjutsu.
• Sakura Haruno asked how she could grow strong enough to bring back her friend, and Aizen recommended studying Blut Arterie, Blut Vene, Nature Energy manipulation, Kido, and Spiritual Power.
• Sakura Haruno began studying with determination while Shikamaru Nara watched in dismay as the others committed themselves to Aizen's curriculum.

Shikamaru Nara resisted joining his companions’ obsessive research until Sosuke Aizen challenged his belief that he was a genius. Stung by Aizen’s criticism, Shikamaru headed to the laboratory to prove himself, where he unexpectedly encountered Sakura and Ino.

• Shikamaru watched from his room as Sakura, Ino, and Shino spent weeks conducting intense research with Aizen’s support.
• Aizen confronted Shikamaru and called him an ordinary, unproductive student whose supposed genius had never produced results.
• Shikamaru admitted to himself that he had relied on his reputation and clan techniques instead of developing his own abilities.
• After Shikamaru asked Aizen to teach him, Aizen explained he had only come to replace Sakura and Ino’s destroyed clothes and protect his reputation.
• Determined to prove Aizen wrong, Shikamaru dressed and went to the laboratory, where Sakura and Ino shouted at him for interrupting them.

Sosuke Aizen assessed the self-destructive tendencies of Sakura Haruno, Ino Yamanaka, Shikamaru Nara, and Shino Aburame, but Tsunade defended the harsh training as necessary for survival in the Ninja World. After confronting Tsunade over Konoha’s covert adoption of his spiritual techniques, Aizen agreed to a training competition against Neji Hyuga, Tenten, and Rock Lee in a month.

• Sosuke Aizen reviewed information about Sakura Haruno, Ino Yamanaka, Shikamaru Nara, and Shino Aburame and judged their interests and behavior to be shaped by the Ninja World’s violent culture.
• Tsunade told Sosuke Aizen that the children should pursue their own goals and argued that rigorous training gave them the strength to protect themselves.
• Sosuke Aizen asked Tsunade about the Mind’s Eye Blade and natural-environment spirit particle technology, then revealed that he had detected Konoha ninjas developing Spiritual Power and Zanpakuto traits.
• Tsunade challenged Sosuke Aizen to an internal Konoha training competition, proposing Neji Hyuga, Tenten, and Rock Lee as opponents for his students.
• Sosuke Aizen accepted the competition, which was to take place after his training class temporarily concluded in a month.

Aizen explained why he was gradually changing Konoha through research rather than force, then told his students their month of training had ended and they needed to prove their abilities in a simulated match. The students negotiated to keep working in the Testing Ground and began planning a way to fool their opponents with clones.

• Aizen reflected that Konoha's resistance to his technology stemmed from political interests, and that he wanted to preserve the Ninja World as a control group for his experiments.
• Aizen told Ino Yamanaka, Sakura Haruno, Shino Aburame, and Shikamaru Nara that their scheduled training period was over and a match would test what they had learned.
• Ino pleaded to stay and continue her flower experiments, while Sakura revealed her Chakra-Sensing Liquid and Shino protested experiments on insects.
• Aizen agreed to let them continue researching in the Testing Ground if they performed well in the simulated match, and the four began planning realistic clones to stand in for them.
• The students assigned roles for their deception plan, with Shikamaru handling realism, Ino using flowers, Sakura providing precise control, and Shino proposing Insect Clones.

Neji Hyuga and his teammates received Tsunade’s order to test four Konoha shinobi whose education had changed them, expecting a deadly fight. Ino Yamanaka, Shikamaru Nara, Sakura Haruno, and Shino Aburame defeated them in turn with bizarre techniques, leaving Tsunade horrified by the results of Sosuke Aizen’s teaching.

• Tsunade ordered Neji Hyuga, Rock Lee, and Tenten to face Shikamaru Nara, Sakura Haruno, Ino Yamanaka, and Shino Aburame in simulated matches and told them to use their full strength.
• Neji Hyuga discovered that the trio would face the four opponents one at a time and understood Tsunade wanted them to kill their former companions.
• Ino Yamanaka incapacitated the trio with Flower Fairy Powder, which slowed and then blocked their Chakra.
• Shikamaru Nara defeated the trio using Chakra absorption and his Fluid Backwash Technique, and Sakura Haruno later trapped them in her Chakra Reversal: Heavenly Net.
• Shino Aburame overwhelmed the trio with swarms of insects, treated their injuries, and left them unconscious as Tsunade watched in horror.

Sosuke Aizen explained to Tsunade how the children’s interests, intensive study, Shadow Clones, and accelerated training had let them make years of progress in one month. Tsunade agreed to allow small-scale promotion of his methods and a year of verification, while Aizen warned he would pursue his goals himself if Konoha did not meet his demands.

• Tsunade watched the children defeat Neji Hyuga, Rock Lee, and Tenten with techniques they had developed during a month of training.
• Aizen explained that the children had effectively trained for fifteen years by combining focused learning, accelerated perception, Shadow Clones, and other support.
• Aizen described his vision of education and urged Tsunade to let talented people choose their own paths, then asked whether his answer satisfied her.
• Tsunade authorized small-scale promotion of Aizen’s techniques but required a year to verify them before any large-scale rollout.
• Aizen warned Tsunade that he would act to obtain what he wanted if Konoha failed to meet his demands, then left the field.
• Tsunade watched the young Ninja awaken and hoped Aizen’s work would destroy the village’s decayed traditions.

After more than two years of training, Naruto and Jiraiya returned to a strangely dilapidated Konoha and met a radically changed Sakura. Jiraiya learned that she was an unusually powerful chakra clone, and he followed her into the village wary of what had happened.

• Naruto and Jiraiya heard rumors that Konoha had declined under Tsunade and hurried back to see the village for themselves.
• At Konoha's ruined gates, Sakura greeted them in a tattered lab coat and led Naruto toward a hall where everyone was waiting.
• Sakura acted unusually familiar with Naruto, then revealed that she was a Chakra Flesh Clone rather than the original.
• Sakura described a chakra-based movement technique called the Subspace Void Technique, confusing Jiraiya and Naruto.
• Jiraiya sensed the clone's immense chakra and followed Sakura into Konoha, suspecting that the village had undergone a major, unexplained change.

Nine Otsutsuki survivors traveled from the future to Rōran, determined to prevent the catastrophic future caused by Sosuke Aizen’s infinite evolution. They secretly strengthened the Tailed Beasts and the Divine Tree, while their leader set out to join the seal on the moon, leaving Aizen with an unexplained sense that something had changed.

• Nine future Otsutsuki appeared in the ruins of Rōran and confirmed they had arrived in the year Uzumaki Naruto returned to Konoha.
• The Otsutsuki leader explained that Aizen’s coming One Day War would lead him to resonate with other worlds and eventually trigger Infinite Divine Wrath.
• The nine agreed to sacrifice themselves by enhancing the Tailed Beasts and the Divine Tree, with their leader assigned to merge with the moon’s seal.
• The Otsutsuki scattered across the Ninja World, secretly attaching Chakra pills to the Tailed Beasts and sending faint lights toward the moon.
• Sosuke Aizen watched Uzumaki Naruto in Konoha and instinctively sensed that something had happened.
