Chapter Summaries

As Konoha’s reconstruction neared completion, Tsunade and Shikamaru sought Rinto’s help with impact-resistant training grounds, construction waste recovery, and emergency shelters. Rinto designed solutions for all three, and their successful rollout supplied him with extensive field data as he turned his attention to deeper mysteries of the world.

• Konoha’s reconstruction leaders reported that damaged training grounds, enormous piles of construction waste, and inadequate emergency shelters had stalled progress.
• Shikamaru explained how all three problems could provide new research opportunities, and Tsunade brought the requirements and samples to Rinto.
• Rinto accepted the work and promised plans in three days, then designed waste-recycling configurations, layered impact-resistant training grounds, and modular protective shelter pods.
• Rinto delivered the manuals, and Tsunade ordered small-scale tests that confirmed the designs worked better than expected.
• Konoha implemented all three systems, while departments sent Rinto daily field data that he used to refine his research.
• With reconstruction nearly complete, Rinto focused on investigating the origin of Chakra, the Sage of Six Paths, the God Tree, and the Otsutsuki.

Konoha completed its reconstruction in six months, and Tsunade brought Rinto forbidden Jutsu records and research notes as thanks. As Rinto studied Tobirama’s notes on Impure World Reincarnation, Kabuto secretly assembled an army of reincarnated dead, and an urgent report from the Land of Fire’s border disrupted Konoha’s peace.

• Konoha finished rebuilding its infrastructure and defenses, drawing astonished envoys from the Land of Fire and other great villages.
• Tsunade and Shizune brought Rinto forbidden Jutsu records, past Hokage research notes, and other gifts, but Rinto accepted only the documents.
• Rinto found Tobirama Senju’s notes on Impure World Reincarnation and recognized their potential for researching souls, regeneration, and ninja abilities.
• Obito advanced the Eye of the Moon Plan while Kabuto perfected Impure World Reincarnation and gathered samples to create an army of reincarnated ninja.
• Disappearances and grave robberies spread across the borders, but the villages treated the incidents as isolated crimes and Rinto remained absorbed in research.
• An urgent battle report arrived from the Land of Fire’s border, breaking Konoha’s peace and presenting Rinto with an unprecedented research sample.

A Konoha patrol squad was ambushed by three enemies who used dead ninja’s techniques and regenerated from fatal injuries, leaving only two survivors. After the survivors warned Tsunade and Konoha’s leaders, Shizune took an enemy’s severed arm for urgent research, whose results promised an unprecedented shock.

• A ten-person Konoha patrol squad found three dead Land of Wind ninja in a Gobi canyon and was ambushed by three cloaked attackers using techniques associated with long-dead ninja.
• The attackers regenerated instantly from devastating injuries and killed half the squad within minutes, forcing the Jonin leader to order a retreat.
• The Jonin leader died holding off the enemies after sealing a fragment of one attacker’s arm and throwing it to his squad; only two Chunin escaped with it.
• The two surviving Chunin reached Konoha and reported the ambush to Tsunade, who examined the fragment and summoned the village’s leaders.
• Tsunade’s leadership discussed the enemies’ abilities, and Shizune took the arm fragment to Konoha’s research team for urgent examination.

Shizune and Konoha’s researchers tested the severed arm of an undying enemy but could not explain its regeneration, foreign chakra, or traces of a bound soul. Tsunade decided to take the sample to Mr. Rinto, the only person she believed could uncover its secrets.

• Shizune brought the arm fragment to Konoha’s advanced laboratory, where researchers found it still regenerating a day after it was severed.
• The researchers discovered extraordinarily active cells, mixed genetic sequences, three kinds of chakra, and traces of soul fragments bound inside the cells.
• Shizune tried to stop the regeneration with Yang Release chakra, but the fragment’s sinister binding chakra repelled her.
• Tsunade, Shikamaru, and Kakashi reviewed the test results and admitted they could not understand the fragment or find a way to counter it.
• Tsunade decided to take the sample to Mr. Rinto, despite the risk of disturbing him.

Tsunade brought Rinto a fragment of an enemy whose body could regenerate endlessly and wield a dead ninja’s Kekkei Genkai. Rinto identified it as an improved Impure World Reincarnation sample and began examining it, while Tsunade ordered Konoha to investigate who had revived the forbidden jutsu.

• Tsunade brought Shikamaru and Shizune to Rinto’s courtyard and offered him the fragment, test data, and a report on the border attack.
• Rinto recognized the sample’s traits as Impure World Reincarnation and eagerly invited the group inside to study it.
• Rinto examined the fragment and found a dead person’s soul imprint embedded in its cells, bound by a caster’s control imprint that sustained its regeneration.
• Rinto kept the sample, told Tsunade to bring him any related samples or information, and identified the jutsu as one developed by the Second Hokage Tobirama Senju.
• Tsunade ordered border patrols to prioritize their safety and investigate who had mastered Impure World Reincarnation.
• Rinto took the fragment to his laboratory and began recording its cellular, soul-binding, and chakra-imprint mechanisms.

Rinto deciphered the core mechanisms and weaknesses of Impure World Reincarnation while Konoha’s forces struggled against its undying reanimated ninja. He told Tsunade he had a countermeasure but withheld it until he could study more samples, beginning with fragments from the reanimated former Tsuchikage Ōnoki of Both Scales.

• Reanimated ninja attacked all four borders of the Land of Fire, and Tsunade sent their fragments and combat reports to Rinto for study.
• Rinto determined that Impure World Reincarnation bound soul fragments throughout the body, used chakra to reconstruct it, and relied on a caster’s control spell.
• Rinto identified two ways to release the dead: erase the caster’s control imprint or let the dead person break free of its suppression.
• Rinto told the messengers that he understood the technique and had a countermeasure, but asked Konoha to keep bringing him different samples.
• Tsunade ordered the frontline troops to prioritize collecting reanimated samples and prepare to deploy Rinto’s countermeasure once it was ready.
• Rinto began examining fragments from the reanimated Ōnoki of Both Scales to study his Dust Release and Kekkei Tōta.

Rinto dissected the cellular structure and regeneration mechanism of Impure World Reincarnation, identifying how soul imprints and control formulas enabled reanimated bodies to rebuild themselves and where the technique could be countered. He kept his findings from Konoha and welcomed new samples from the front lines for further research.

• Rinto compared reanimated cells with ordinary, Yang Release-enhanced, and modified corpse cells, finding soul imprints and caster control formulas embedded in their nuclei.
• Rinto recorded how soul templates reproduced the deceased's body and abilities while control formulas suppressed their consciousness, maintained the binding, and supplied Chakra.
• Rinto damaged reanimated samples in controlled tests and observed their bodies reconstructing from surviving cells through Chakra converted into matter.
• Rinto identified three ways to stop the technique: seal a reanimated body, erase its control formulas, or terminate the caster's Impure World Reincarnation.
• Rinto encrypted his findings without informing Konoha, then ordered the newly arrived samples from Kirigakure's Seven Ninja Swordsmen of the Mist and Konoha's Ino-Shika-Cho clan heads brought into the laboratory.

As Konoha struggled against increasingly powerful Impure World Reincarnation attacks, Tsunade and Shikamaru traded Tobirama Senju's original forbidden jutsu notes to Rinto for a battlefield countermeasure. After studying the notes, Rinto produced two teachable methods and sent them to the front, while looking forward to researching the unusual reincarnated fighters the war would bring.

• Konoha's leaders discussed mounting casualties from Impure World Reincarnation and agreed to offer Rinto Tobirama Senju's original research notes in exchange for a usable countermeasure.
• Tsunade and Shikamaru brought the sealed notes to Rinto, who accepted them and promised a countermeasure in three days.
• Rinto studied Tobirama's notes, compared the original jutsu with its improved version, and identified weaknesses in the improved technique.
• Rinto developed a precision talisman-erasure method and an easier sealing formula, along with combat guidance for frontline ninja.
• Tsunade and Shikamaru received Rinto's scroll and manuals and hurried back to distribute the countermeasures, while Rinto anticipated studying future reincarnated fighters.

Rinto’s countermeasure enabled Konoha to break Impure World Reincarnation and sharply reduce frontline casualties. While Konoha celebrated, he studied the jutsu’s soul-release mechanisms and received new samples from a previous Raikage and a previous Mizukage.

• Tsunade distributed Rinto’s manual and ordered Konoha’s ninja to train in its countermeasures and teach them across the front lines.
• Konoha’s teams used the talisman-erasure method to release reanimated ninja’s souls, reversing the battlefield situation and reducing casualties.
• Rinto dissected the jutsu’s binding stages and verified how his configuration erased control talismans and released souls from reanimated bodies.
• Rinto determined that the full-scale jutsu could be ended by interfering with its control links or killing its caster, but kept those methods out of Konoha’s manual.
• Ninja brought Rinto fragments from a previous Raikage of Kumogakure and a previous Mizukage of Kirigakure, and he began examining their abilities.

Rinto dissected the Raikage’s Lightning Release Chakra Mode and the Mizukage’s Lava Release, then built a vast sample library and a genetic model explaining Kekkei Genkai as inherited chakra configurations. As his research reshaped his understanding of chakra, a fragment of Hashirama Senju’s Wood Release arrived, leaving Rinto poised to investigate its connection to life energy and deeper powers.

• Rinto scanned the former Raikage’s fragment and found that specialized cellular receptors and inherited chakra-conversion configurations enabled Lightning Release Chakra Mode.
• Rinto dissected the former Mizukage’s Lava Release and identified genetic configurations that fused multiple chakra attributes by overcoming their natural repulsion.
• Over the next half month, frontline ninja delivered samples from across the shinobi world, and Rinto analyzed them while expanding his all-type sample library.
• Rinto classified Kekkei Genkai into nature-transformation, bodily-function, and secret-technique types, defining them as inherited configurations for chakra application.
• Two wounded ninja delivered a sealed fragment of Hashirama Senju, and Rinto placed its Wood Release cells into his highest-precision testing instrument.

Rinto deconstructed Hashirama Senju’s Wood Release cells and concluded that their life-creating power combined water-earth chakra, Yin-Yang Release, and senjutsu chakra. After recording and optimizing his findings, he received word that Madara Uchiha had appeared on the front lines and ordered the new samples brought to him.

• Rinto examined Hashirama Senju’s cells and found that they had immense life energy, could absorb natural energy, and could assimilate ordinary cells.
• Rinto determined that Wood Release’s life creation depended on Yin-Yang Release, while water-earth chakra provided its material form and senjutsu chakra fueled its growth.
• Rinto deconstructed Wood Release techniques, optimized their chakra efficiency, and devised a method to prevent transplanted cells from causing backlash.
• Rinto connected the cells’ chakra imprint to Asura and six paths power, then archived his findings on life creation and Wood Release.
• A ninja told Rinto that Madara Uchiha had appeared through Impure World Reincarnation and that the front line had recovered Susanoo fragments and bodily tissue.
• Rinto ordered Madara’s samples brought to him so he could study the Sharingan, Susanoo, and Yin Release.

Rinto analyzed samples from Madara Uchiha and uncovered the principles behind the Sharingan, Susanoo, and Madara’s fused bloodlines. He gave the shinobi who brought the samples a brief account of Madara’s abilities and weaknesses, leaving them to carry possible counters back to the front line.

• Madara Uchiha overwhelmed the Allied Shinobi Forces, and two shinobi brought fragments of his body and a Susanoo chakra crystal to Rinto in Konoha.
• Rinto examined Madara’s cells and found that Hashirama Senju’s cells, Indra’s chakra imprint, and a faint Rinnegan imprint had fused within them.
• Rinto concluded that the Sharingan amplified and applied yin release chakra, and that its advanced abilities and blindness resulted from the strain of using that power.
• Rinto analyzed the Susanoo crystal and determined that Susanoo was a Yin-Yang Release creation whose form depended on a Yin Release framework and Yang Release physical structure.
• After two days of research, Rinto gave the shinobi written explanations of Madara’s abilities, their weaknesses, and possible counters, then asked them to bring him more samples.

Rinto analyzed a vast collection of shinobi samples, refining his general models of Chakra, Kekkei Genkai, and Sealing Jutsu while identifying techniques’ weaknesses. The chapter ended with an urgent report that countless unfamiliar white life-forms had attacked the Allied Forces and could absorb Chakra and copy Ninjutsu.

• Rinto analyzed the Hozuki Clan sample and uncovered how the Hydrification Technique worked and what could counter it.
• He examined Uzumaki Clan samples and Sealing Jutsu, then derived and optimized their underlying rules.
• Rinto analyzed samples from numerous Kekkei Genkai and clan techniques, expanding his Chakra theory and creating a general model for Kekkei Genkai.
• He finished processing more than a hundred samples and prepared to study samples from reincarnated Jinchūriki and Tailed Beast Chakra.
• A shinobi reported that white life-forms had appeared at the front, absorbed Chakra, copied Ninjutsu, and inflicted severe casualties on the Allied vanguard.

Rinto analyzed White Zetsu’s cellular structure, abilities, weaknesses, and countermeasures, then prepared a report for the Allied Shinobi Forces. Before he could study the samples, a messenger reported that reincarnated past jinchūriki had appeared with control over the Tailed Beasts, and the front had collapsed.

• Two ninja delivered sealed White Zetsu specimens and asked Rinto to find a way to counter them.
• Rinto examined the specimens and determined that White Zetsu cells could assimilate other life, imitate identities, absorb chakra, replicate ninjutsu, and regenerate from tiny fragments.
• Rinto identified White Zetsu’s vulnerabilities and wrote practical countermeasures for the Allied Shinobi Forces.
• Rinto archived his research and prepared a concise report for the front.
• A frantic ninja reported that reincarnated past jinchūriki had appeared, wielded Tailed Beast power, and overwhelmed the front.

Rinto analyzed samples from reincarnated Jinchūriki to explain tailed beast chakra, the Jinchūriki symbiosis system, and how Tailed Beast Bombs worked, then gave the Allied Shinobi Forces a handbook of countermeasures. Just as he returned to his research, he learned that Madara Uchiha had freed himself from Impure World Reincarnation and was heading toward Allied Forces headquarters.

• Two ninjas brought Rinto samples from reincarnated Jinchūriki and Tailed Beast Bomb explosions, asking him to find countermeasures.
• Rinto analyzed Rasa's cells and identified three levels of Jinchūriki and Tailed Beast symbiosis.
• Rinto studied tailed beast chakra and recorded the distinct chakra characteristics of the Nine Tailed Beasts.
• Rinto worked out how Tailed Beast Bombs formed and erupted, then devised ways to evade, disrupt, absorb, or counter them.
• Rinto completed a handbook of countermeasures for the frontline commanders and Sealing Squad ninjas.
• A panicked messenger told Rinto that Madara Uchiha had broken free of Impure World Reincarnation and was advancing toward Allied Forces headquarters.

Rinto analyzed Madara’s self-rewritten Impure World Reincarnation and prepared countermeasures for the Allied Shinobi Forces. Just as the front received his handbook, Madara joined the Masked Man to revive the Ten-Tails.

• A messenger brought Rinto samples of Madara’s body and chakra after Madara defeated the Five Kage and escaped Impure World Reincarnation’s control.
• Rinto determined that Madara had anchored his soul to his cells and made his body’s chakra supply and regeneration self-sustaining.
• Rinto identified ways to counter Madara, including severing his soul’s bond to his body, disrupting energy absorption, targeting his soul, or sealing him in an isolated space.
• After two days of research, Rinto gave a handbook of Madara’s weaknesses and countermeasures to the commanders, who rushed to relay it to the front.
• A messenger reported that Madara had joined the Masked Man, and they were using the Demonic Statue of the Outer Path and tailed beast chakra to revive the Ten-Tails.

Rinto went to the Fourth Shinobi World War battlefield to study the Demonic Statue of the Outer Path and the origins of Chakra. As he recorded the fusion of the Seven Tailed Beasts’ Chakra, the Ten-Tails revived, while Madara and Obito noticed the mysterious researcher observing them.

• Rinto learned the battlefield’s location, opened a spatial rift, and traveled from Konoha to the allied forces’ position.
• Rinto told Kakashi Hatake and the others that he had come for research samples, then hurried toward the Demonic Statue of the Outer Path as the Tailed Beasts’ Chakra began fusing.
• Rinto reached a vantage point less than a kilometer from the statue and recorded its Chakra changes while Madara Uchiha and Obito watched him with suspicion.
• Rinto observed the Seven Tailed Beasts’ Chakra return to a primordial form and begin combining into the Ten-Tails’ Chakra.
• The Demonic Statue of the Outer Path transformed, grew ten tails, and revived as the Ten-Tails.

The Ten-Tails transformed into its more precise second form and launched attacks against the Allied Shinobi Forces, while Rinto secretly diverted its long-range strike aimed at headquarters. The four Hokage arrived to intercept the Ten-Tails’ bombardment, and Hashirama and Madara prepared to face each other.

• The Ten-Tails fired a destructive Tailed Beast Bomb at Naruto, Kakashi, Killer B, and Might Guy, and Killer B and Naruto diverted it away from the allied troops.
• Obito guided the Ten-Tails through its transformation into its second form, then ordered it to target the Allied Shinobi Forces headquarters with a compressed long-range Tailed Beast Bomb.
• Rinto silently transported the bomb away from headquarters and into the distant sea, leaving the command center unharmed.
• Obito ordered the Ten-Tails to bombard the allied position with dozens of Tailed Beast Bombs, overwhelming the defenders and causing heavy casualties.
• Minato Namikaze, Hashirama Senju, Tobirama Senju, and Hiruzen Sarutobi arrived, and Minato and Tobirama transported most of the incoming bombs away.
• Madara confronted Hashirama as Rinto prepared to record the battle.

Obito fought Kakashi in the Kamui Dimension, learned the truth about Rin’s death, and broke free of Madara’s control. He absorbed the Ten-Tails and became Six Paths Obito, leaving the Allied Forces facing a new overwhelming power.

• Obito unleashed the Ten-Tails’ Wood Release: Cutting Sprigs against the Allied Forces while Hashirama protected the shinobi and fought Madara.
• Kakashi confronted Obito, and the two entered the Kamui Dimension to settle their conflict.
• Kakashi revealed that Rin had deliberately sacrificed herself to protect Konoha, causing Obito’s certainty in his plans to waver.
• Madara used the Black Receivers to force Obito to prepare Rinne Rebirth, but Obito resisted and began sealing the Ten-Tails into himself.
• Obito endured the violent fusion and emerged as the Ten-Tails Jinchuriki, Six Paths Obito.

Obito stabilized his Six Paths power, broke the Four Red Yang Formation with a Truth-Seeking Orb, and overwhelmed the Allied Forces. Rinto secretly collected a sample of the orb’s energy and diverted some of Obito’s attacks, while Obito prepared a massive strike to end the war.

• Obito suppressed the Ten-Tails’ will, and Hashirama Senju, Tobirama Senju, Minato Namikaze, and Hiruzen Sarutobi trapped him in the Four Red Yang Formation.
• Obito used a Truth-Seeking Orb staff to dissolve the barrier, while Rinto recorded the technique and secretly collected a sample of its energy.
• Naruto Uzumaki and Sasuke attacked Obito, but his Truth-Seeking Orb shield nullified their attacks, and Tobirama Senju explained that only senjutsu and pure taijutsu could harm him.
• Obito launched a barrage of Truth-Seeking Orb spikes at the Allied Forces; Minato Namikaze and Tobirama Senju teleported some away, while Rinto secretly sent others to the sea.
• Obito gathered a powerful sphere of Ten-Tails chakra in his palm as Rinto observed his still-imperfect control.
