Chapter Summaries

Uchiha Sou studied Gelel energy and ordered research into how it could stabilize Hashirama Cells, while expanding surveillance of the Land of Demons ahead of the priestess succession. He left plans in motion to influence Madara’s evolution and investigate the tensions surrounding Mōryō and the new priestess.

• Shinnō reported that Gelel energy promoted cellular activity and regeneration, and tests showed it made Hashirama Cells more controllable.
• Sou ordered a secret research project to develop a life energy stabilizer using Gelel energy’s effects on biological tissue.
• Sou directed his intelligence network and ninja cats to gather information about the Land of Demons, the priestess succession, Shion’s future mother, and Yomi Cult activity.
• Sou observed the priestess’s life energy and Mōryō’s darkness fluctuating as the succession approached, and considered the ceremony a possible opportunity to intervene.
• Sou adjusted research resources and issued new orders while monitoring Gelel energy, Madara’s unstable Chakra, and readings from the Land of Demons.

Uchiha Sou used stabilized Gelel energy to help Uchiha Madara fuse with Hashirama Cells, easing the rejection and greatly increasing his power. Madara still needed time for his Yin and Yang energies to settle before he could awaken the Rinnegan.

• Sou offered Madara Gelel energy to guide the fusion, and Madara agreed in exchange for experimental records and Sou’s promised intelligence.
• Madara guided the azure energy into his body, enduring a painful process as it forced his Hashirama Cells and Chakra toward an orderly balance.
• The fusion succeeded, stabilizing Madara’s Chakra and letting him wield his Perfect Susanoo more easily and combine it with the Wood Golem Technique.
• Madara declared that he was closer to awakening the Rinnegan, while Sou warned that the fused energies needed months or years to settle.
• Madara resumed his cultivation in the cavern, and Sou left with experimental data and a deeper understanding of Yin and Yang fusion.

Uchiha Sou watched Uchiha Madara’s Yin-Yang power approach the Rinnegan awakening while the crisis surrounding Miroku and Mōryō in the Land of Demons neared its climax. As the coming storm gathered, Sou prepared to reap the results of the causes he had set in motion.

• Uchiha Sou observed Gelel energy steadily merging Uchiha Madara’s Yin Release Chakra and Hashirama Senju’s cells into a stable dark-gold power, bringing the Rinnegan close to awakening.
• Little Black and Sou’s other intelligence sources reported worsening nightmares, tighter guards at Miroku’s palace, and signs of Yomi cult activity in the Land of Demons.
• Uchiha Sou saw Miroku’s protective power struggle to contain Mōryō as the cultists’ plan to exploit the shrine maiden transition reached its final stage.
• Uchiha Sou sensed the imminent fusion of threads representing fanaticism, ignorance, destruction, and extreme yang, and declared that he would reap the fruits of Causality as the storm approached.

Uchiha Madara awakened the Rinnegan after Yin Release, Yang Release, and Gelel energy fused, gaining a new perception of Chakra and laws. The eyes’ power rapidly consumed his life force, but he accepted the cost and set his sights on the Eye of the Moon.

• Uchiha Sou witnessed Madara’s causal line transform as his Yin and Yang powers fused under the influence of Gelel energy.
• Madara opened his Rinnegan, and the awakening sent a ripple through the surrounding land and sky.
• Madara perceived Chakra, earth veins, and distant life and conflict in unprecedented detail.
• Madara formed a repulsive field with a thought and crushed a boulder into powder.
• Madara felt the Rinnegan draining his life force and accelerating his body’s decline, though Gelel energy buffered the cost.
• Madara accepted the price, adapted to his new power, and declared that the path to the Eye of the Moon was clear.

As Uchiha Madara awakened the Rinnegan and unleashed a vast upheaval in causality, Uchiha Sou’s Mangekyō Sharingan completed its transformation and awakened Fruit Reaping. Sou gained the ability to sense causal fruits and potentially harvest them, while Madara faced the heavy life-force cost of his new power.

• Uchiha Madara perceived the world through the Rinnegan’s vision of Chakra and natural laws, but felt the Eyes of the Sage rapidly draining his life force.
• The ripples from Madara’s awakening struck Uchiha Sou’s Dojutsu Power, while Light felt an unexplained disturbance and Mirror moved protectively closer to her.
• Uchiha Sou endured an overwhelming influx of pain and visions, including the consequences of his past actions and possible futures connected to them.
• Uchiha Sou’s Mangekyō Sharingan transformed, allowing him to sense causal threads and the fruits at their ends, with the potential to harvest them.
• Uchiha Sou declared that the stage was set and the feast had begun.

Uchiha Sou contacted Uchiha Madara after Madara awakened the Rinnegan, then collected samples and data to study the eyes’ effects. Sou discovered that the Rinnegan acted as a causal engine that consumed and assimilated its host’s life, while Madara continued adapting to his new power.

• Uchiha Sou asked Uchiha Madara for detailed Rinnegan data and arranged to send a stealth collection unit.
• Uchiha Madara allowed the unit to scan him and collect blood and tissue samples before it returned to Angkor Fortress.
• Uchiha Sou examined the Rinnegan sample through his causal perspective and identified it as a rule-defining causal singularity.
• Uchiha Sou found that the Rinnegan consumed Madara’s life force and gradually assimilated his causality, despite Gelel energy slowing the damage.
• Uchiha Sou analyzed the sample to deepen his knowledge of the Rinnegan and his own powers while Uchiha Madara continued adapting to his eyes.

Uchiha Madara summoned the Demonic Statue of the Outer Path, while Uchiha Sou used his dojutsu to observe Black Zetsu’s hidden influence and quietly steer its plans. Sou arranged for Madara and Black Zetsu to become more likely to notice a red-haired boy with Uzumaki blood.

• Uchiha Madara summoned the Demonic Statue of the Outer Path and sensed its connection to his Rinnegan.
• Uchiha Sou detected the statue’s arrival and recorded its energy and causal effects from Angkor Fortress.
• Uchiha Sou traced Black Zetsu’s influence on Madara’s history and saw it trying to draw closer to Madara’s bond with the statue.
• Black Zetsu considered finding an Uzumaki vessel and a backup executor for its plan.
• Uchiha Sou subtly influenced Madara and Black Zetsu to seek a powerful, vulnerable proxy, making a red-haired boy with Uzumaki blood more likely to attract their attention.

Madara awakened the Demonic Statue of the Outer Path, discovered Yin–Yang Release, and unintentionally gave Black Zetsu a chance to take form and deceive him. Cang observed Black Zetsu’s emergence from Angkor Fortress as a new connection between it and Madara formed.

• Madara summoned the Demonic Statue of the Outer Path, and a few thousand unfinished White Zetsu emerged around it.
• Madara experimented with Yin–Yang Release and formed a shifting substance infused with creation and destruction.
• Black Zetsu exploited Madara’s creation to take form, then claimed it was the manifestation of Madara’s will.
• Madara questioned Black Zetsu, but its advice about gathering the Tailed Beasts, using the Uzumaki Clan, and finding an agent persuaded him to spare it for now.
• Cang watched the events through Netherworld Manifestation and noted the new creator-and-created connection between Madara and Black Zetsu.

As the Second Great Ninja War erupted, Uchiha Madara and Uchiha Sou met to plan how to exploit the conflict to gather the Tailed Beasts and advance the Eye of the Moon Plan. Sou agreed to track the Jinchuriki and study the White Zetsu, while Black Zetsu remained hidden and wary of him.

• The Second Great Ninja War spread across the nations as Madara began adapting to the Rinnegan and summoned the Demonic Statue of the Outer Path.
• Uchiha Sou warned Madara that using the Rinnegan recklessly would drain his life, and advised waiting for the war to weaken the villages before targeting vulnerable Tailed Beasts.
• Madara and Sou agreed to locate displaced Uzumaki survivors for experiments while preserving Sou's protected Uzumaki clansmen for their skills.
• Sou proposed analyzing and programming the White Zetsu to improve their use as an intelligence network, and Black Zetsu hinted that the statue could help them grow.
• Madara tasked Sou with tracking all nine Tailed Beasts and their Jinchuriki, while Sou concealed his knowledge of Black Zetsu's true nature.
• After Sou vanished, Black Zetsu warned Madara that Sou was dangerous, but Madara insisted he could control and use him.

Madara reviewed White Zetsu’s reports on several Uzumaki descendants and chose Nagato as the best future vessel for the Rinnegan, while Uchiha Sou’s subtle interference reinforced that decision. Sou ordered Nagato’s family watched and protected as he continued overseeing Hikari’s training at Angkor Fortress.

• Black Zetsu presented Madara with reports on several Uzumaki, including a weakened woman imprisoned in Kusagakure and Nagato, whose exceptional Chakra and intact family made him a promising candidate.
• Madara chose Nagato as a potential Rinnegan vessel and ordered Black Zetsu to monitor and protect his family, while marking the other Uzumaki as possible reserves or test subjects.
• Uchiha Sou observed Madara’s decision and considered the nearly spent Uzumaki Mihai’s role as a decoy and precursor to descendants such as Karin.
• At Angkor Fortress, Sou explained a barrier diagram to Hikari and described the war-torn Land of Rain as a place that might nurture special vitality.
• Kagami silently noted Sou’s interest in the Land of Rain as a possible part of his plans.

Uchiha Sou sent Kagami Uchiha to steal samples of Mōryō’s dark energy and Miroku’s priestess power during the succession ceremony in the Land of Demons. Kagami also retrieved Uzumaki Mihai from Kusagakure, leaving Sou with rare energy samples and a fading Uzumaki subject for further experiments.

• Uchiha Sou ordered Kagami Uchiha to infiltrate the priestess succession ceremony and secretly collect traces of Mōryō’s energy and Miroku’s sealing power.
• As Mōryō attacked the seal during the ceremony, Kagami captured both energy samples without being noticed by the priestesses.
• Light sensed the distant clash of opposing energies and recognized Kagami’s Chakra signature, while Kagami’s clone recorded her unusual sensitivity.
• Uchiha Sou ordered Kagami to detour to Kusagakure and retrieve Uzumaki Mihai, whose bloodline and vitality had nearly faded.
• Kagami collected Uzumaki Mihai’s tissue and blood, returned with her and the energy samples, and Sou sent her to cryogenic storage for possible experiments.

Madara arranged for Nagato to receive an implanted fragment of the Rinnegan’s power, then had White Zetsu kill Nagato’s parents to awaken it through grief. Yahiko and Konan found the orphaned Nagato and took him in, while Sou secretly watched the new bonds form and prepared to exploit the events.

• Madara told Sou that Nagato was the ideal Rinnegan vessel and planned to awaken his hatred by having White Zetsu kill his parents.
• Kagami Uchiha used a special scroll linked to Sou to imprint a hidden Shinra Tensei seed into Nagato’s eyes.
• White Zetsu, disguised as Konoha ninja, killed Nagato’s parents, triggering the seal and causing Nagato to unleash a repulsive force before collapsing.
• Yahiko and Konan found Nagato beside his parents’ bodies and carried him to their shelter, with Konan placing a paper flower in his hand.
• White Zetsu reported the encounter to Madara, while Sou observed the new bonds among Nagato, Yahiko, and Konan and continued his research at Angkor Fortress.

After Shaton died, Sunagakure’s new Third Kazekage approved a secret invasion of the Land of Rain to secure resources and strengthen his rule. Uchiha Sou observed the resulting upheaval and welcomed the growing chaos as cover for his plans.

• Shaton died after entrusting Sunagakure to his young successor, the future Third Kazekage.
• Several days later, Chiyo and other elders urged the Third Kazekage to launch a preemptive strike, citing Sunagakure’s dwindling resources and threats from Konoha and Iwagakure.
• An intelligence elder proposed targeting southern Land of Rain while Konoha and Iwagakure focused on each other.
• The Third Kazekage approved Operation Sand Fangs and ordered Sunagakure’s forces to assemble secretly for an assault on southern Land of Rain.
• Uchiha Sou observed Sunagakure’s aggressive intent and judged the conflict useful for concealing his plans amid widespread chaos.

Sunagakure prepared a swift raid on the Land of Rain while Hanzo misread its movements and focused on threats in the north. Uchiha Sou watched without intervening as the attack began, leaving the Land of Rain’s southern defenses breached.

• Elder Chiyo gathered Sunagakure’s elite forces and ordered them to strike and plunder the Land of Rain, withdrawing if Konoha or Iwagakure intervened.
• Nagato, Yahiko, and Konan struggled to survive in the war-torn Land of Rain as Hanzo focused his attention on the northern front.
• Hanzo dismissed reports of Sunagakure’s unusual movements as routine border patrols and sent more scouts north.
• Uchiha Sou observed Sunagakure’s impending attack and chose not to interfere, seeing the resulting chaos as useful to his plans.
• Sunagakure’s puppet army ambushed an Amegakure patrol at the southern border, killing its members and opening the attack.

Sand Village’s brutal invasion devastated the Land of Rain, driving Nagato, Yahiko, and Konan into hiding and pushing Hanzo to retaliate. As Hanzo set out for the southern battlefield, Uchiha Sou watched the forces of Causality converge and anticipated that their destruction would nourish his final “fruit.”

• Sand Village’s puppet forces and special assault units slaughtered civilians and Amegakure defenders, looted settlements, and poisoned wells across the southern Land of Rain.
• Nagato, Yahiko, and Konan hid in a collapsed irrigation channel, where Nagato struggled with traumatic memories, Yahiko seethed with rage, and Konan tried to keep them calm.
• Hanzo received reports of the invasion’s atrocities and ordered the Poison Cocoon unit to assemble, the First and Fourth Combat Brigades to prepare, and the Death Rain plan to begin.
• Hanzo dismissed an elder’s concern about Rain Village survivors and rushed toward the battlefield, declaring that the demigod was going hunting.
• Uchiha Sou observed the forces of Causality bringing Hanzo, Sand Village, and the surviving trio toward a violent collision, and said their suffering would nourish the final fruit.

Hanzo launched a surprise attack on Chiyo’s Sand Village force in a rain-shrouded river valley, slaughtering ninja and destroying puppets with his speed and chained kama. He summoned his salamander and unleashed lethal poison, forcing Chiyo to retreat while Hanzo remained in control of the valley.

• Chiyo halted the Sand Village advance to scout the poisonous mist, but Hanzo ambushed the vanguard and killed three ninja.
• Hanzo used his Body Flicker Technique and chained kama to break through the Sand Village formation and kill more ninja.
• Chiyo deployed the Chikamatsu Three Puppets, but Hanzo damaged the Dharma puppet and kept attacking the troops around them.
• Chiyo used the Monk puppet to raise a barrier, but Hanzo struck it hard enough to crack it.
• Hanzo summoned his salamander, whose poisonous mist corroded puppets and killed Sand Village ninja.
• Chiyo ordered a full retreat and withdrew with her surviving puppets as Hanzo watched the Sand Village force flee.

After Sunagakure suffered a devastating defeat at Hanzo’s hands, the Third Kazekage met him and negotiated a temporary truce. Their fragile agreement redirected their shared hostility toward Konoha, which Uchiha Sou watched with interest from Angkor Fortress.

• Chiyo assessed Sunagakure’s losses, including damaged puppets and fallen elite ninja, after Hanzo’s poison mist routed her forces.
• The Third Kazekage ordered Chiyo to withdraw, fortify her position, treat the wounded, and refrain from further attacks without his command.
• The Third Kazekage met Hanzo alone in a rainy valley and argued that Konoha and Iwagakure would benefit if Sunagakure and the Land of Rain continued fighting.
• The Third Kazekage proposed a temporary secret truce, intelligence sharing, and possible covert cooperation against their northern enemies.
• Hanzo accepted the temporary truce, and the Third Kazekage warned that Sunagakure would face Hanzo’s poison if it broke the agreement.
• Uchiha Sou observed the two powers’ Causality entwining and welcomed their new hostility toward Konoha.

The Sand Village, Hanzo, and Hatake Sakumo prepared for the next stage of their conflict as Hanzo secretly moved north to lure Sakumo into an ambush at Withered Bone Gorge. From Angkor Fortress, Uchiha Sou watched the opposing forces converge and anticipated the coming battle.

• Chiyo studied Hanzo's poison and planned sealed, air-filtering puppets and traps, while ordering Sand scouts to monitor Hanzo's clashes with Konoha's White Fang.
• Hanzo secretly redeployed his brigades north and decided to personally lure Sakumo into a poison-mist ambush at Withered Bone Gorge.
• Sakumo learned that Rain forces were gathering north and that reports pointed to Withered Bone Gorge, so he warned his troops not to act without orders and strengthened defenses against poison.
• Sou observed Hanzo's forces targeting Sakumo's Konoha contingent through his Netherworld Manifestation and anticipated their confrontation.
• The Seed of Causality within Nagato's Rinnegan trembled as Sou looked forward to the conflict feeding his plan.

Sand Village and Amegakure ambushed Hatake Sakumo’s forces as Iwagakure invaded the western border, forcing Hiruzen Sarutobi to dispatch reinforcements. Kagami Uchiha infiltrated the Hidden Leaf to strengthen Sou’s hidden plans and discovered Root’s surveillance of the Uchiha, leaving him determined to protect Xiyue and Ayako.

• Chiyo’s puppet forces struck Sakumo’s flank while Hanzo attacked from the front, and Sakumo ordered his troops to regroup as Iwagakure invaded the Land of Grass.
• Hiruzen ordered Jiraiya, Orochimaru, and Tsunade to reinforce the Land of Rain and sent Torifu Akimichi to defend the western border.
• Sou sent Kagami to the Hidden Leaf to inspect and expand planted Causality seeds and observe the village’s response, especially the Uchiha.
• Kagami secretly entered the village, checked existing Chakra metal plates, and planted additional rune-metal plates at key locations.
• Kagami watched Xiyue awaken his Single Tomoe Sharingan during training and saw Ayako care for him.
• Kagami detected Root surveillance around the Uchiha compound and resolved to monitor Danzō while protecting Xiyue and Ayako.

As war strained the Hidden Leaf Village, Uchiha Sou monitored its people and the wider Ninja World from Angkor Fortress while directing covert experiments and interventions. He recognized that the Rinnegan was hastening Uchiha Madara’s decline, and Black Zetsu sensed an unknown observer as Sou sent a White Zetsu spore toward the border between the Land of Earth and the Land of Fire.

• Xiyue Uchiha trained under a Chunin instructor while Ayako Uchiha watched with Kagami Uchiha’s keepsake.
• Hiruzen Sarutobi spoke with Jiraiya about the fighting, dwindling medical supplies, and suspected dealings between Sand Village and Amegakure.
• Kagami Uchiha reported on the Hidden Leaf Village to Uchiha Sou, warning that Danzō and Root threatened the Uchiha and possibly the Jinchuriki.
• Uchiha Hikari tested a dangerous Hashirama Cells fusion on an unconscious subject, but the experiment triggered severe rejection and mental collapse.
• Uchiha Sou observed that using the Rinnegan was draining Uchiha Madara’s life force, while Madara coughed blood and Black Zetsu sensed an unfamiliar gaze.
• Uchiha Sou sent a hidden White Zetsu spore toward the Land of Earth–Land of Fire border to further intensify the war.
