Chapter Summaries

Gengetsu discovered that Black Zetsu had ambushed his Shadow Clone and rescued the White Zetsu, while Obito remained in Madara Uchiha’s hands. Minato, Kakashi, Rin, and Gengetsu searched for Madara’s hideout but found only a trapped maze of tunnels, leaving Gengetsu to reconsider how he could uncover their location.

• Gengetsu used Dragon Vein Chakra to revive one Uchiha clansman, but Black Zetsu immobilized his Shadow Clone and freed the White Zetsu after the clone dispelled.
• Gengetsu realized that Obito might possess both Mangekyo Sharingan and warned himself to be more cautious around Black Zetsu.
• Gengetsu’s Shadow Clone met Minato, Kakashi, and Rin after their mission at Kannabi Bridge and told them Madara Uchiha had taken Obito and controlled the Ten-Tails’ shell.
• The Shadow Clone was destroyed while Gengetsu was explaining the enemy, and Minato, Kakashi, and Rin resolved to investigate and try to bring Obito back.
• Minato and the others searched Madara Uchiha’s underground maze but failed to find his hideout, and Gengetsu regretted not keeping a White Zetsu for information before going to Jiraiya’s command center.

Gengetsu explained to Jiraiya why Nagato was likely still alive and how Madara Uchiha planned to use hatred, Obito, and the Zetsu as safeguards. He returned to Konoha with Kakashi and Rin, where Hiruzen Sarutobi approved Gengetsu’s research and agreed to bring Tsunade back to the village.

• Gengetsu argued that Madara Uchiha needed Nagato alive to revive him and had chosen Obito as a pawn to carry out his plans.
• Jiraiya decided to report the threat to Hiruzen Sarutobi, while Gengetsu warned that bringing Kakashi and Rin back to Konoha would not guarantee their safety.
• Gengetsu left the Land of Rain that night with Jiraiya’s letter, leaving Uchiha Shinsui behind, and later met up with Minato, Kakashi, and Rin.
• Minato agreed with Gengetsu’s plan, then headed for the Land of Hot Water as Gengetsu escorted Kakashi and Rin back to Konoha.
• Hiruzen Sarutobi approved Gengetsu’s research, accepted its estimated one-billion funding cost, and agreed to transfer Tsunade back to the village.

• Kushina agreed to cultivate Nine-Tails Chakra Mode, and Gengetsu prepared to help her draw on the Nine-Tails' pure Chakra.

Gengetsu and Kushina tried to extract Kurama’s Chakra before Madara Uchiha could use him, while Gengetsu and Ao Cang restrained the raging Nine-Tails. Kushina resisted Kurama’s malice and successfully pulled a Nine-Tails made of pure Chakra from his body as Hiruzen Sarutobi arrived with ANBU in the Forest of Death.

• Kushina released Kurama from his restraints in the Sealed Space, and he attacked as Gengetsu prepared to intervene.

• Kushina overcame Kurama’s malice and extracted a Nine-Tails made of pure Chakra from his body.
• Hiruzen Sarutobi arrived at the Forest of Death with a squad of ANBU ninja.

Kushina mastered a risky form of Nine-Tails Chakra Mode, and Hiruzen Sarutobi learned she could use its Malice Sensing to hunt spies in Konoha. Gengetsu pursued White Zetsu underground while Kushina and the ANBU began a village-wide spy purge.

• Kushina used Nine-Tails Chakra Mode after taking some of the Nine-Tails' Chakra, and Gengetsu warned her that Kurama would drain more Chakra whenever she used Shadow Clones.

• Gengetsu suggested using Kushina's Malice Sensing to locate spies and White Zetsu Clones, and Kushina sensed five White Zetsu hiding underground.
• Gengetsu entered Dragon Vein Chakra Mode and pursued the White Zetsu, but it detected him and escaped, leaving him with only half its head.
• Hiruzen Sarutobi ordered the ANBU to work with Kushina, who began hunting spies across Konoha while Gengetsu gathered supplies and another Shadow Clone taught Rin the Spirit Transformation Technique.

Gengetsu and Tsunade pursued two methods of cultivating a clone that could fuse with White Zetsu and First Hokage cells, while Gengetsu advised Kakashi on developing a lightning-based combat style. Their experiment succeeded when a White Zetsu clone entered Sage Mode and used Sage Art: Spore Technique.

• Tsunade warned that Rin might not master the Spirit Transformation Technique in time, so Gengetsu arranged for his Shadow Clone to train her while they pursued a second experimental plan.
• Gengetsu Sun reported that experiments using Rin's cells had failed, so Tsunade and Gengetsu began cultivating clones using Rin's cells and Gengetsu's cells respectively.
• Gengetsu watched Kakashi train in Lightning Release Chakra Mode and suggested he develop a Lightning Release High-Frequency Vibration Blade.
• Gengetsu rushed back to the Laboratory Base after Gengetsu Sun announced the clone was complete.
• Gengetsu's Shadow Clone used the Spirit Transformation Technique to control the White Zetsu clone, which entered Sage Mode and used Sage Art: Spore Technique to consume a discarded clone.

Gengetsu tested the Sage Art-enhanced Spore Technique, discovering that it could imitate people, transfer chakra, heal wounds, and evade even Sage Mode detection. He then mastered Metal Release before learning that the Third Raikage had died in battle and that the Third Hokage had summoned him.

• Gengetsu and Tsunade observed a Spore Clone transform into Shizune, evade sensory detection, and transfer chakra to Kaori.
• The Spore Clone healed a wound in the White Zetsu clone by sacrificing and regrowing an arm, then spread undetected spores among everyone present.
• Tsunade said her experiments would take much longer, so Gengetsu continued cultivating and studying White Zetsu ninjutsu.
• As fighting continued on the Land of Rain front, Gengetsu mastered Metal Release in the Forest of Death.
• An ANBU ninja told Gengetsu that the Third Raikage had died in the Land of Earth and that the Third Hokage wanted him at the Hokage Office.

Gengetsu learned that the Third Raikage had died after fighting Iwa Ninja alone, then received orders to join the Hidden Mist front while Hiruzen and Danzo handled the Land of Rain. He began Obito’s plan by making a Spore Sage duplicate Rin, and Rin agreed to serve as bait if the clone was exposed.

• Gengetsu assessed the Third Raikage’s death and concluded that Konoha had benefited from the conflict between the Cloud Ninja and Iwa Ninja.
• Hiruzen Sarutobi assigned Gengetsu, Kakashi, and Rin to a temporary squad and ordered them to escort Tsunade back to the front lines, while Danzo said he would go to the Land of Rain with Jiraiya.
• Gengetsu told Tsunade he would proceed with Obito’s plan and brought a White Zetsu clone to Rin’s training site.
• Gengetsu used the Spore Technique to create a Spore Sage that absorbed Rin’s Chakra and transformed into a perfect duplicate of her.
• Rin volunteered to become the bait if the duplicate was exposed, and Gengetsu prepared a Summoning Scroll so he could summon her to safety.

Gengetsu arrived at the front lines with Tsunade and used his healing techniques to restore many wounded Konoha ninja, prompting Tsunade to plan an offensive built around his Shadow Clones. He then recognized Fugaku Uchiha’s newly awakened Mangekyō Sharingan and warned him and Shisui Uchiha that Madara Uchiha had begun controlling Uchiha clansmen.

• Gengetsu, Kakashi, and Rin escorted Tsunade, Shizune, and Kaori to the front lines, while Gengetsu worried that Kakashi might detect that Rin was not herself.
• Gengetsu healed the wounded at the Medical Outpost with Shadow Clones, Katsuyu, and the Strength of a Hundred Technique, raising Konoha’s morale.
• Tsunade decided that Konoha’s squads would follow Gengetsu into battle the next day to avoid a prolonged war of attrition.
• Gengetsu noticed Fugaku Uchiha’s altered Chakra and recognized that he had awakened the Mangekyō Sharingan.
• Gengetsu privately warned Fugaku Uchiha and Shisui Uchiha that Madara Uchiha had controlled two Uchiha clansmen with Three-Tomoe Sharingan.

Gengetsu led Konoha’s counterattack against the Mist Ninja, using his Shadow Clones to drive the enemy back to the coast. After weeks of victories, he felt his eyes beginning to transform and prepared to awaken a new form of Byakugan.

• Gengetsu learned that Shisui might awaken the Mangekyo Sharingan before the war ended, then attended Tsunade’s meeting, where she ordered an all-out counterattack led by his Shadow Clones.
• Gengetsu’s Shadow Clones and Konoha’s elite attacked the Mist Ninja, using powerful ninjutsu, Ice Release, and Uchiha fighters to defeat the enemy forces.
• Gengetsu learned that Suikazan Fuguki and Karatachi Yagura were among the Mist Ninja, and he sent a Shadow Clone after Fuguki to pursue Samehada.
• Konoha won battles for roughly half a month and pushed the front along Wave Country to the coast.
• Gengetsu sensed that his eyes were changing due to Sage Transformation, notified Tsunade with a Shadow Clone, blindfolded himself, and waited for them to transform.

Gengetsu’s eyes began transforming as he started Sage Transformation of his Internal Organs, but the Mist Ninja captured his Spore Sage clone and sealed the Three-Tails inside it. Kakashi helped the clone escape, then stayed behind to hold off their pursuers while Gengetsu faced the danger of being trapped with a Tailed Beast inside him.

• Gengetsu realized four sources of power were transforming his eyes and began Sage Transformation of his Internal Organs to complete the process.
• Little Katsuyu reported that the Mist Ninja had captured Gengetsu’s Spore Sage clone, and Gengetsu sensed the Six-Tails appearing on the battlefield.
• Gengetsu summoned his White Zetsu clone and sent it to deal with Obito while he went to confront the Six-Tails.
• In the southern Land of Fire, Gengetsu’s clone awakened as Rin, discovered the Three-Tails and a Cursed Seal inside its body, and added an Eight Trigrams Sealing Style.
• Kakashi rescued Rin from the cave, but Mist Ninja surrounded them, and Kakashi stayed behind to hold off the pursuers as Rin fled.

Gengetsu discovered that Rin had been summoned away and rushed with Kakashi to stop Madara Uchiha and Black Zetsu’s plan. Obito arrived in time to witness Rin’s death, awakened his Mangekyō Sharingan, and charged at the Mist Ninja in anguish.

• Little Katsuyu told Gengetsu that Rin had been taken by a Summoning Technique, and Gengetsu revealed his identity to Kakashi.
• Gengetsu sensed Rin’s location, killed the pursuing Mist Ninja with Wood Release, and explained that Madara Uchiha meant for Obito to witness Rin’s death.
• White Zetsu disguised as Gengetsu controlled Rin with a Three-Tomoe Sharingan and prepared a scene for Obito to witness.
• Obito raced toward Rin after learning she was in danger and saw her run herself onto White Zetsu’s Gengetsu’s blade.
• Obito awakened the Mangekyō Sharingan, realized the Gengetsu who had attacked the Mist Ninja was a Shadow Clone, and charged at the Mist Ninja as wooden spikes tore through his arm.

Gengetsu and Kakashi discovered that Obito had taken Rin’s body after Madara’s scheme led to her death, leaving Gengetsu unable to track or revive her. Back at the medical outpost, Gengetsu decided to leave the Three-Tails’ fate to the Third Hokage, while accepting that the war’s losses might help unite the ninja villages later.

• A White Zetsu clone found Rin’s body missing, and Kakashi broke down after Gengetsu confirmed she was gone.
• Gengetsu released his seals and used the Three-Tails’ Chakra to search for Rin, but Obito had hidden her body in Kamui Space.
• Gengetsu deduced that Madara had prepared Rin and the surrounding events in advance to make Obito blame him for her death.
• Gengetsu supported Kakashi back to camp, where they learned Gengetsu’s main body had defeated the Six-Tails but failed to capture it.
• Tsunade heard the account and questioned what to do with the Three-Tails; Gengetsu chose to let the Third Hokage decide after the war.

Gengetsu grieved Rin’s death, resolved to pursue resurrection and end the war, and continued training as Kirigakure retreated. After inviting Hiashi Hyuga and Hizashi Hyuga to witness his transformation, he revealed that his newly changed eyes resembled the Byakugan.

• Gengetsu blamed himself for Rin’s death, considered possible resurrection techniques, and decided to study Impure World Reincarnation after the war.
• As Kirigakure suffered defeats and withdrew from the Land of Fire, Gengetsu sent Kaori to ask Tsunade for reconnaissance on its command headquarters so he could plan a surprise attack.
• Gengetsu considered training paths for Kaori and Naohide, then felt a faint throbbing between his brows that suggested his Heavenly Eye might emerge.
• Five days later, Hiashi Hyuga and Hizashi Hyuga visited Gengetsu, who asked the Hyuga Clan to bear witness to his eye transformation.
• After two hours of training, Gengetsu opened his changed eyes and declared that they were the Byakugan.

Gengetsu’s Sage Transformation awakened a Heavenly Eye, and he explained the Hyuga Clan’s ancient connection to the Otsutsuki lineage to Hyuga Hiashi and Hizashi Hyuga. After they parted on friendly terms, Gengetsu reflected on the Hyuga Clan’s political position and its lack of top-tier fighters.

• Gengetsu’s Sage Chakra fused seven Chakra natures, forming a Heavenly Eye in his forehead as Hyuga Hiashi and Hizashi Hyuga watched in shock.
• Gengetsu used the Heavenly Eye to perceive the Caged Bird Seal imprinted on Hizashi Hyuga’s soul, then explained that his Byakugan awakening came from Sage Art and shared ancestry.
• Gengetsu told Hyuga Hiashi and Hizashi Hyuga that they descended from Hamura Otsutsuki, while Kaguya Otsutsuki was their ancestral matriarch.
• Hyuga Hiashi and Hizashi Hyuga accepted Gengetsu’s account, and Hyuga Hiashi shared Byakugan techniques with him for an hour before the brothers left.
• Gengetsu considered how Konoha’s anti-clan policy had weakened the Hyuga Clan and questioned why it lacked powerful fighters comparable to the Uchiha.

Gengetsu completed another stage of Sage Transformation and set out to visit Kirigakure, claiming he wanted to discuss peace with the Third Mizukage. He attacked a Mist Ninja command island from the air, destroying it with Ao Cang’s Divine Dragon Spiraling Sphere.

• Gengetsu tested his Byakugan and Heavenly Eye, then used Unity of Heaven and Man to refine Sage Chakra for two hours.
• Gengetsu used the Sage Chakra to deepen his Sage Transformation and sensed his cells, internal organs, and pineal gland growing stronger.
• Tsunade told Gengetsu that preparations were complete and Sunagakure had been contacted for simultaneous attacks.
• Gengetsu asked to visit Kirigakure, and Tsunade agreed on the condition that he take Little Katsuyu and avoid recklessness.
• Gengetsu flew to the Mist Ninja command island and ordered Ao Cang to destroy it with Divine Dragon Spiraling Sphere.

Gengetsu destroyed Kirigakure’s frontline command headquarters, searched the captured Hozuki Awabiko’s memories, and sent the intelligence to Tsunade as Konoha launched its counteroffensive. He defeated a large Mist Ninja reinforcement force at sea and headed toward Kirigakure, while his Shadow Clone kept Awabiko captive.

• Gengetsu found Hozuki Awabiko alive after destroying the island and searched his memories for Kirigakure’s intelligence.
• Gengetsu relayed the Mist Ninja’s deployments and fighters’ abilities to Little Katsuyu, who passed them to Tsunade as she ordered Konoha and Sunagakure to attack.
• Gengetsu froze Awabiko’s water-transformed body when he tried to escape, then confronted six ships carrying more than four hundred Mist Ninja.
• Gengetsu froze and shattered the Mist Ninja’s waves, then used four Dragon Vein Rasenshuriken and purple lightning to defeat the force.
• Gengetsu left a Shadow Clone to secure the survivors and flew toward Kirigakure, while the clone assured Awabiko that he intended to make peace with the Third Mizukage.

Gengetsu infiltrated Kirigakure and confronted the Third Mizukage, claiming he had come to negotiate peace. He warned that Kirigakure would lose the war and revealed information about a mysterious organization manipulating the Five Great Ninja Villages, leaving the Mizukage to decide whether to keep fighting.

• Gengetsu sent a Shadow Clone to attack Kirigakure’s defenses while his main body slipped through the village barrier in disguise.
• Gengetsu confronted the Third Mizukage outside the Mizukage Building and insisted he had come for friendly talks, despite the destruction caused by his clone.
• Gengetsu claimed he had destroyed Kirigakure’s frontline command headquarters, captured Hozuki Awabiko, and dealt with reinforcements, then argued that Kirigakure would lose against Konoha and Sunagakure.
• Gengetsu told the Third Mizukage that an organization operating under Madara Uchiha was provoking wars and had killed the Third Kazekage and possibly the Third Raikage.
• Gengetsu warned that one member of the organization could absorb Chakra, impersonate others, and evade Chakra sensing, and said the corpse Kirigakure had found had appeared as one of their own ninja.

Uzumaki Gengetsu accompanied Kirigakure’s peace envoys to Konoha and met Kisame Hoshigaki, whose respect for him led them to discuss training and the horrors of war. Gengetsu began to suspect that Kisame might have been sent on a mission to kill his fellow envoys.

• The Third Mizukage dismissed objections from Kirigakure’s elders and ordered envoys to begin peace talks with Konoha, believing Konoha would likely accept Kirigakure’s claim to Wave Country.
• Gengetsu read Kirigakure’s proposed terms, speculated that the Third Mizukage might be connected to White Zetsu, and focused on ending the war before Black Zetsu could exploit it.
• Gengetsu met the Kirigakure envoys and recognized Kisame Hoshigaki among them; the two showed mutual respect despite being enemies.
• Gengetsu traveled by ship with the envoys to protect the negotiations, and Kisame approached him on deck to praise his strength and dedication to cultivation.
• Gengetsu and Kisame discussed the demands of training and the brutality of war, and Gengetsu wondered whether Kisame had been assigned to kill his fellow envoys.
