Chapter Summaries

Shinji completed the Type Four Aging Potion and warned Sasuke about the risks of rushing into another fight with Upper Moon Two. After Sasuke chose to face the demon again, Shinji took him to the Icefield north of the Land of Iron to begin the mission.

• Shinji confirmed that the Type Four Aging Potion had been successfully formulated and named it, though he could not measure how much stronger it was than Type Three.
• At a Konoha training ground, Sasuke demanded to know why Tsunade's team had not taken him to fight Upper Moon Two.
• Shinji cautioned Sasuke that his recovered Dojutsu could take months or longer to recover again and urged him to prepare a new strategy.
• The next night, Sasuke resolved to challenge Upper Moon Two again, and Shinji agreed to leave with him.
• Shinji had Sasuke leave a Shadow Clone in the village, then used his Lamp ability to teleport them to the Icefield north of the Land of Iron, where Sasuke announced his arrival.

Kokushibo escaped Mifune and the Land of Iron samurai, then attacked Sasuke when he encountered him with Shinji and Yakumo. As the Third Tsuchikage and Fourth Raikage moved their armies onto the snowfield to hunt Upper Moon Two, Sasuke and Shinji pursued him into the storm.

• Kokushibo killed several Land of Iron samurai before Mifune confronted him, then fled when a signal flare revealed the Iwagakure Ninja Army was nearby.
• Mifune decided the samurai should join the Iwagakure Ninja Army rather than pursue Upper Moon Two alone.
• Kokushibo recognized Shinji and Yakumo as Akatsuki members and launched a surprise attack on Sasuke, whose Susanoo blocked the strike.
• Kokushibo fled into the snowstorm, and Sasuke and Shinji chased after him.
• Mifune joined the Third Tsuchikage's forces, while the Fourth Raikage ordered the Kumogakure Ninja Army to search for Upper Moon Two before Iwagakure could claim him.

After three days of pursuing Kokushibo across the snowy plains, Sasuke was caught between the demon and the allied shinobi forces. The Third Tsuchikage and Fourth Raikage agreed to cooperate, but the fighting continued as the Raikage attacked Sasuke and Shinji confronted Kokushibo.

• Sasuke relentlessly pursued Kokushibo for three days while the allied forces surrounded them across the snowy plains.
• The Third Tsuchikage and Fourth Raikage agreed that Iwagakure would receive Kokushibo for research, while Kumogakure would help capture the two Akatsuki Organization members.
• The allied forces charged Kokushibo and Sasuke, and the Fourth Raikage forced both fighters to dodge his blow.
• The Fourth Raikage abandoned Kokushibo and attacked Sasuke, demanding to know where Yugito Nii was.
• Sasuke tried to evade the Raikage and return to the pursuit, but the Raikage blocked his path and attacked him.
• Shinji blocked Kokushibo after Kokushibo killed several Iwagakure shinobi.

Shinji tested the Type Four Aging Potion on Kokushibo during the snowstorm, using the Ketsuryūgan to restrain him long enough to inject it. As Kokushibo’s body decayed and his mind deteriorated, he fled with Shinji following, and they slipped through the Joint Force’s encirclement.

• Shinji approached Kokushibo after Iwagakure and Kumogakure began a joint operation, and Kokushibo attacked him with Moon Breathing, Tenth Form: Piercing Face Slash, Waning Moon.
• Shinji blocked Kokushibo’s blades with Susanoo, used the Ketsuryūgan to raise blood blisters on him, and injected him with the Type Four Aging Potion.
• Kokushibo fled into the storm as the potion took effect, causing him to spit blood, suffer bodily decay, and lose mental clarity.
• Kokushibo attacked and feasted on several Kumogakure ninja, while Shinji observed the potion’s apparent effect on his mind.
• Kokushibo fled on all fours with Shinji pursuing him, and the two passed through the Joint Force’s encirclement under cover of the storm.

Shinji pursued the deteriorating Kokushibo while Sasuke escaped the Fourth Raikage and later confronted the demon. Sasuke wounded Kokushibo with Chidori, but Kokushibo escaped after cutting Sasuke eleven times.

• Shinji tracked Kokushibo through the snowstorm and noted that the Type Four Aging Potion was still damaging his body after nearly fifteen minutes.
• Sasuke escaped the Fourth Raikage, then followed Shinji's guidance toward Kokushibo.
• Sasuke trapped Kokushibo in a concealed steel-wire net and prepared to finish him with Amaterasu.
• Kokushibo burst free with his Evil Blades and attacked Sasuke, who struck him with Chidori and blew away half his body.
• Kokushibo regenerated and fled into the blizzard, while Sasuke discovered he had suffered eleven blade wounds.

Shinji and Sasuke pursued the weakened Kokushibo across the snowfield as Shinji assessed the Type Four Aging Potion’s effects. A Konoha squad led by Tsunade encountered Kokushibo and the two Akatsuki members following him, and Shinji’s Shadow Clone attacked before the squad could intervene.

• Shinji confirmed that the Type Four Aging Potion had suppressed Kokushibo for twenty-five minutes and decided Sasuke could finish him off.
• Tsunade’s squad resumed its search across the snowfield after the blizzard eased, but the harsh conditions limited their scouting.
• Yakumo and Shibi Aburame spotted Kokushibo approaching with two Akatsuki members, whom the squad recognized as A and E.
• Tsunade ordered the squad not to move, but Shinji’s Shadow Clone charged at Kokushibo.
• Shinji’s Shadow Clone unleashed Fire Release: Great Fire Annihilation, engulfing Kokushibo in flames.

Shinji’s Shadow Clone burned Kokushibo to ash, then Shinji fought Akatsuki Organization’s ‘A’ with powerful Fire Release and a carefully prepared Explosive Tag trap. As the Joint Force approached, ‘A’ and ‘E’ withdrew from the battlefield.

• Shinji’s Shadow Clone used Great Fire Annihilation to destroy the weakened Kokushibo, who died and turned to ash.
• Shinji confronted ‘A’, forcing him to evade a series of powerful Fire Release attacks while Tsunade’s team and Sasuke watched.
• Shinji’s Shadow Clone retreated and triggered steel wires linked to Explosive Tags, engulfing ‘A’ and his golden Susanoo in explosions.
• ‘A’ signaled ‘E’, and the two Akatsuki members withdrew before the approaching Joint Force arrived.

Shinji’s deception allowed him to destroy Upper Moon Two’s remains and withdraw with Sasuke, but the arriving Kage suspected Konoha had captured the demon and accused Sasuke of being Akatsuki’s ‘E’. The chapter ended with Tsunade and Jiraiya troubled by the Raikage’s evidence about ‘E’ and Sasuke’s Lightning Release skills.

• Shinji’s Shadow Clone told Tsunade he had gotten carried away, while the squad praised him for driving off Akatsuki’s ‘A’ and ‘E’.
• Shinji concealed that he had staged the battle and used Magatsu to supply his Shadow Clone with Chakra as it launched Fire Release attacks.
• The Third Tsuchikage and Fourth Raikage arrived and learned from Shinji that Upper Moon Two had turned to ash.
• The Joint Force found no trace of Upper Moon Two, leading the Kage to suspect Konoha had captured and sealed him.
• The Fourth Raikage accused Sasuke of being Akatsuki’s ‘E’, citing his purple Susanoo, inexperience, and skill with Lightning Release.

After the Kage refused to pay Shinji’s bounty for Upper Moon Two, Tsunade and Jiraiya reported the snowy plain events and questioned whether Sasuke was Akatsuki’s “E.” Back in Konoha, the Third ordered Kakashi to test Sasuke, and their spar began under his watch.

• The Third Tsuchikage and Fourth Raikage claimed they could not pay Shinji’s bounty until Upper Moon Two’s death was verified, then left.
• Tsunade and Jiraiya discussed the similarities between Sasuke’s Susanoo and Akatsuki’s “E” before Jiraiya sent a report to Konoha.
• Sasuke returned to his apartment, frustrated that Shinji had killed the demon he had pursued for three days and nights.
• Kakashi attacked Sasuke at his apartment, and the two fought through the village until they reached a training ground.
• Kakashi revealed his Sharingan, and he and Sasuke began a Lightning Release-enhanced spar while the Third watched from a tree.

Kakashi tested Sasuke in a sparring match and, after recognizing Sasuke’s growing arrogance, used the fight to teach him practical ninja skills. Sasuke ended the chapter bound in a tree while the village leaders watched.

• Sasuke taunted Kakashi and claimed his speed and strength were beyond Kakashi’s, while Kakashi resolved to teach him a lesson.
• The Third, Danzo, Utatane Koharu, and Mitokado Homura debated whether Sasuke was an impostor and why the Akatsuki might be involved.
• Sasuke attacked Kakashi with Fire Release techniques and ninja tools, binding him behind an earth wall before striking with Dragon Fire.
• Sasuke discovered that the Kakashi struck by his Chidori was a Lightning Clone, then was trapped by wires around a tree.
• Kakashi told the immobilized Sasuke that using ninja tools was his new lesson.

Kakashi defeated Sasuke and warned him against caring only about victory, while the village elders debated whether Sasuke should be watched. After Tsunade's squad returned from the Land of Iron, the Third Hokage awarded the squad mission credit and gave Shinji an S-rank credit for killing Upper Moon Two.

• Kakashi trapped Sasuke in steel wires, then freed him and criticized him for ignoring the risks of failure.
• The Third Hokage and the elders discussed monitoring Sasuke, but the Third postponed the decision to avoid undermining his plan to win Sasuke over.
• Tsunade and Jiraiya reported the Land of Iron mission to the Third Hokage, including the suspicions about Sasuke raised by the Third Tsuchikage and Fourth Raikage.
• The Third Hokage accepted Shinji's explanation for attacking Upper Moon Two alone and judged his actions appropriate.
• The Third Hokage awarded Tsunade's squad one A-rank mission credit each and gave Shinji one S-rank mission credit for killing Upper Moon Two.

After Shinji was celebrated for killing Upper Moon Two, Utatane Koharu offered him a place in her personal ANBU unit, but he chose to remain at the Ninja Academy. She then assigned him to monitor Sasuke, Naruto, and Yakumo, unaware that Shinji led the Akatsuki Organization.

• Jiraiya encouraged Shinji to take pride in defeating Upper Moon Two, and Yakumo asked him to treat their classmates to barbecue.
• Utatane Koharu offered Shinji a direct promotion to Genin and a place in her personal ANBU unit, but Shinji declined and chose to stay at the Ninja Academy.
• Utatane Koharu assigned Shinji to investigate whether Sasuke had secretly joined the Akatsuki Organization.
• Utatane Koharu also ordered Shinji to watch Naruto Uzumaki and Kurama Yakumo for weaknesses the Advisor Elder Council could use against the Third.

Shinji celebrated with his classmates after killing Upper Moon Two and revealed that he had declined an offer to join ANBU so he could remain at the Ninja Academy. Later, he reflected on the danger posed by the Demon Slayer World and the possibility that an Overlord was behind its invasion.

• Shinji joined his classmates for dinner, where they congratulated him and discussed how he killed Upper Moon Two, while Sasuke privately resented Shinji receiving the credit.
• Yakumo asked Shinji about the Elder advisor’s plan to send him into ANBU, and Shinji confirmed the offer but said he had turned it down to stay with his friends.
• Naruto celebrated Shinji’s decision, while Karin and Haku felt relieved that he would remain at the Academy.
• Sasuke left the restaurant fuming, and Neji felt melancholy as he compared his lack of progress with his classmates’ achievements.
• Shinji returned to his apartment and worried that an Overlord had set its sights on the Shinobi World, explaining that he had let demons roam partly to test whether the mysterious man could still invade.

Shinji weighed the danger of investigating the Demon Slayer World and focused on slowing its contamination of the Shinobi World. After weeks of hunting demons, he found nine remained and decided that eliminating the Upper Moon Five held by Konoha was his most urgent task.

• Shinji considered whether invading the Demon Slayer World could expose the Shinobi World to the Overlord and kept releasing Kaguya Otsutsuki as a desperate fallback plan.
• Shinji learned from his Lantern that the worlds might collide in a year and eight months, though interference from other Lanterns could make its estimate unreliable.
• Shinji worried that Konoha's interrogation of Upper Moon Five could reveal contaminating information about the Demon Slayer World and Lantern Bearers.
• Over the following weeks, Shinji hunted down demons scattered across the Shinobi World and used his Lantern to locate the nine that remained.
• Shinji found that Upper Moon One, Upper Moon Three, and Muku were hiding in the Land of Water, while the other demons were held by Konoha, other villages, Orochimaru, or the Akatsuki Organization.
• Shinji decided to deal with Upper Moon Five in Konoha as soon as possible, before the village could extract dangerous information from him.

Shinji infiltrated the interrogation room disguised as a Root shinobi, killed Upper Moon Five, and left the village investigating the incident. He burned his disguise and then sensed something at Karin’s apartment.

• Kurenai failed to extract information from Upper Moon Five, while Ibiki said the village had not approved Sasuke Uchiha’s involvement.
• Root shinobi entered to examine Upper Moon Five, and an alarm soon revealed that one of them was an intruder who had abducted him.
• Ibiki and Kurenai found two Root shinobi unconscious or dead and Upper Moon Five reduced to ash; Tsunade concluded an intruder had killed him.
• The Third Hokage ordered Tsunade to question the surviving Root shinobi and Ibiki to investigate the interrogation unit, then took Danzo aside.
• Shinji burned his Root disguise and, after sensing something, looked excitedly toward Karin’s apartment.

Karin’s Eternal Mangekyō Sharingan stirred and grew stronger, convincing Shinji that it had begun evolving into the Rinnegan. Unsure of the exact process, Shinji reasoned that Karin needed vast amounts of Chakra and began planning to supply it through Magatsu.

• Karin’s Eternal Mangekyō Sharingan stirred briefly, and she told Shinji that it had stopped.
• Shinji examined Karin’s eyes and found that their Dojutsu had grown stronger, widening the gap between them and his own eyes.
• Shinji told Karin that the Rinnegan awakening they had awaited was about to happen, though he did not know exactly what she should do.
• Shinji reasoned that awakening the Rinnegan required a massive accumulation of Chakra and noted that Karin’s body and eyes gave her a strong foundation.
• Shinji considered using Magatsu to channel Chakra from himself and several allies into Karin.

Shinji prepared a secret attempt to awaken the Rinnegan in Karin, using Yugito Nii as a reserve source of Chakra. At his hidden laboratory, Karin began the process, and Shinji supplied Yugito Nii’s Chakra when Karin’s reserves started to fail.

• Shinji chose a secret laboratory outside Konoha and arranged to bring Yugito Nii to the Land of Fire.
• Shinji notified Haku, Shion, Yakumo, Sasuke, and Kimimaro to stay ready for possible Chakra extraction.
• Shinji and Karin sneaked out of Konoha and reached the laboratory, where he prepared the instruments and calmed her nerves.
• Karin channeled Chakra into her Eternal Mangekyo Sharingan, triggering the Power of All Things as Shinji monitored her condition.
• When Karin’s Chakra weakened after more than two hours, Shinji sent her Yugito Nii’s Chakra through the “Magatsu” channel.
• Karin continued channeling the new Chakra, and the instruments showed the Eternal Mangekyo Sharingan’s fluctuations returning to their peak.

Shinji used Chakra drawn from Yugito Nii, Yakumo, Sasuke, and finally himself to stimulate the transformation of the Eternal Mangekyō Sharingan implanted in Karin. Karin opened her eyes with a newly formed pair of Rinnegan, leaving Shinji amazed at what he had created.

• Yakumo and Ido wondered why the Kurama Clan leader had summoned Yakumo’s Chakra, while Sasuke resentfully waited for his Chakra to be taken.
• Shinji exhausted Yugito Nii’s Chakra through the ‘Magatsu’ channel, then drew Yakumo and Sasuke’s Chakra to raise the fluctuations in Karin’s Eternal Mangekyō Sharingan.
• Yakumo and Sasuke ran out of Chakra, and Shinji chose not to draw from his other candidates, instead channeling his own Chakra into Karin.
• Karin opened her eyes as her red pupils turned pale purple and their spirals settled into circles, forming a pair of Rinnegan.
• Shinji watched Karin’s new Rinnegan and exclaimed that he had created them.

Shinji helped Karin awaken the Rinnegan, and she demonstrated its attraction and repulsion abilities. He planned to take the eyes after Karin had stabilized, while using them to help strengthen his own eyes and prepare for a future First Hokage cell transplant.

• Karin awakened the Rinnegan and demonstrated Banshō Ten'in and Shinra Tensei to Shinji.
• Shinji decided to wait until Karin had stabilized before taking the Rinnegan, and gave her contact lenses to conceal its pupils.
• The next morning, Yakumo and Sasuke arrived at the Ninja Academy exhausted after Shinji had drained their Chakra the previous night.
• Yakumo and Sasuke wondered what Shinji had been doing the night before.

After Karin awakened the Rinnegan, Shinji learned that Kumogakure had supposedly located Yugito and joined a mission led by Jiraiya to assist them. Shinji discovered Yugito was still in her cave but had broken free of his genjutsu, suggesting the reported discovery was a trap.

• Karin showed no adverse reaction to awakening the Rinnegan, and Naobi reported that her power and physical constitution were still improving.
• An ANBU messenger summoned Shinji to the Hokage Building, where the Third Hokage announced that Kumogakure had found Yugito Nii and requested assistance.
• Shinji used Naobi to locate Yugito and realized she had broken free of his genjutsu but remained in the cave, apparently waiting to lure him into a trap.
• Jiraiya led ten teams out of Konoha, with Shinji assigned to Tsunade's team alongside Yakumo and Shizune, while Sasuke joined Kakashi's team.
• Tsunade explained that Kumogakure had tracked Yugito using a sensory technique that detected her powerful Chakra signature after she entered the Land of Fire.
