Chapter Summaries

Chapter Summary: Susanoo vs. the Eight-Tails and Two-Tails

Key Plot Points and Events

• The Fourth Raikage charges into Konoha’s camp but is caught in Nara Shikaku’s carefully prepared trap.
• Shikaku uses a feint involving countless shadow-like figures to lure the Raikage into the correct position, then activates the Four Red Yang Formation, trapping him inside a powerful barrier.
• The Fourth Raikage attacks the barrier repeatedly but cannot damage it. Shikaku explains that the formation requires four Kage-level chakra sources to maintain.
• The Raikage notices that the barrier is being maintained by strange figures resembling Hashirama Senju and Madara Uchiha, though their eyes contain the wrong dōjutsu. Shikaku does not reveal what they are.
• Meanwhile, Uchiha Ensei’s Perfect Susanoo overwhelms Killer B and the Eight-Tails. Killer B’s smaller Tailed Beast Bombs prove ineffective.
• Yugito Nii finally achieves a Complete Tailed Beast Transformation as the Two-Tails and attacks the Susanoo. Her claws, fangs, flames, and agility allow her to damage the Susanoo slightly and accelerate the exhaustion of Ensei’s ocular power.
• While the Two-Tails distracts Ensei, the Eight-Tails begins gathering a massive Tailed Beast Bomb.
• The Two-Tails accidentally meets Ensei’s Sharingan gaze and falls under genjutsu. Ensei then seizes her, cuts off one of her ears, and seals the detached Tailed Beast chakra temporarily in a scroll.
• He strikes the Two-Tails, forcing it to revert and exposing Yugito’s injured body.
• Gyuki takes control of Killer B’s body and demands to know Ensei’s objective. Ensei openly confirms that he wants Tailed Beast chakra and threatens to cut off one of Gyuki’s horns—or take one of his tails—if Gyuki refuses.

Character Developments

• Nara Shikaku demonstrates exceptional tactical skill, successfully predicting the Fourth Raikage’s movements and completing the capture plan despite appearing physically weakened.
• The Fourth Raikage is shown to be extraordinarily fast and powerful, but even his Lightning Release Chakra Mode cannot overcome the Four Red Yang Formation.
• Killer B/Gyuki struggles against the Perfect Susanoo. Gyuki ultimately takes control of B’s body, showing his concern for the Two-Tails and his growing awareness of Ensei’s intentions.
• Yugito Nii and the Two-Tails initially turn the battle around through their agility and flames, but their failure to avoid Sharingan eye contact leaves them vulnerable to genjutsu.
• Uchiha Ensei remains calm and confident throughout the battle. He prioritizes collecting Tailed Beast chakra over simply defeating his opponents and uses the Sharingan, Susanoo, and sealing techniques with ruthless efficiency.

Significant Themes

• Strategy versus raw power: The Fourth Raikage’s overwhelming strength is rendered ineffective by Shikaku’s preparation and the Four Red Yang Formation.
• The danger of the Sharingan: Even powerful Tailed Beasts can be neutralized if they meet an Uchiha’s gaze.
• Weaponization and exploitation: The strange Hashirama- and Madara-like figures, the barrier formation, and Ensei’s extraction of Tailed Beast chakra all suggest that powerful bodies and chakra are being treated as tools.
• Control and autonomy: Yugito loses control to the Two-Tails, while Gyuki takes control of Killer B, emphasizing the unstable relationship between jinchūriki and Tailed Beast.
• Confidence and intimidation: Ensei openly states his objective and threatens Gyuki, demonstrating that he believes his Susanoo gives him complete dominance.

Character Interactions

• Shikaku and the Fourth Raikage: Shikaku taunts and advises the trapped Raikage, presenting the capture as a completed checkmate.
• The Fourth Raikage and the strange puppets/barrier: The Raikage questions Konoha’s methods, but Shikaku refuses to explain the mysterious figures.
• The Two-Tails and Ensei: The Two-Tails attacks Ensei’s Susanoo but is eventually caught through genjutsu and physically subdued.
• Gyuki and Ensei: Gyuki pleads with Ensei not to kill the Two-Tails, while Ensei ignores him and demands Tailed Beast chakra.
• Killer B and Gyuki: Gyuki takes over B’s body during the crisis, revealing the seriousness of the situation and the close bond between host and Tailed Beast.

Chapter Summary

Key Plot Points and Events

• The Eight-Tails agrees to negotiate with Uchiha Ensei, demanding to know why he wants Tailed Beast chakra. Ensei offers to spare Killer B and Yugito Nii, the Two-Tails’ jinchūriki.
• Ensei seals and removes the unconscious Yugito Nii from the battlefield, using her as leverage.
• The Eight-Tails forms an enormous Tailed Beast Bomb and threatens Ensei with it. Ensei accepts the terms and releases Yugito, while the Four Red Yang Formation trapping the Fourth Raikage is dispelled.
• The Fourth Raikage, recognizing that Kumogakure has lost the war and risks losing both its Raikage and Tailed Beasts, announces defeat to Nara Shikaku.
• The Raikage retrieves Yugito and orders Killer B to end the Eight-Tails’ transformation and retreat. However, Killer B warns that he cannot control the Eight-Tails, which fires the massive Tailed Beast Bomb at Ensei.
• Ensei abandons Perfect Susanoo just before the attack, teleporting onto the Eight-Tails’ shoulder. The bomb destroys most of Susanoo and creates a huge crater, but Ensei survives unharmed.
• Ensei forces the Eight-Tails to surrender one of its tails and most of its remaining chakra. He seals the chakra into a scroll, noting that it exceeds the amount of Nine-Tails chakra currently contained in Zero-Two.
• The Eight-Tails returns to Killer B, while the Fourth Raikage remains beside him. Ensei declares that Konoha will negotiate war reparations with Kumogakure.
• Before he can finish, Zero-Two detects an intruder. A mysterious hand grabs Ensei’s shoulder, and he identifies the attacker as Obito Uchiha.

Character Developments

• Uchiha Ensei demonstrates overwhelming confidence and tactical intelligence. He avoids the Eight-Tails’ devastating attack through teleportation and calmly pressures it into surrendering chakra.
• The Eight-Tails shifts from defiance to reluctant cooperation after realizing that Ensei can survive even its strongest attack. It ultimately sacrifices one tail and most of its remaining chakra to protect Killer B and Yugito.
• Killer B loses control of the Eight-Tails’ transformation, unintentionally launching the Tailed Beast Bomb despite the Raikage’s order to retreat.
• The Fourth Raikage accepts Kumogakure’s defeat and prioritizes saving Yugito and Killer B over continuing the battle.
• Nara Shikaku survives the collapse of the Four Red Yang Formation and witnesses the Raikage’s surrender, though he recognizes how close he was to death.
• Obito Uchiha makes a sudden entrance at the chapter’s end, introducing a new and dangerous threat.

Significant Themes

• Power and intimidation: Ensei’s ability to withstand the Eight-Tails’ strongest attack establishes his dominance and makes negotiation possible through fear.
• Pragmatism in war: The Raikage concedes defeat to prevent Kumogakure from suffering even greater losses, while Ensei accepts surrender rather than destroying the village outright.
• The cost of survival: The Eight-Tails sacrifices part of itself to preserve its jinchūriki and ally, reinforcing the bond between Tailed Beasts and humans.
• Deception and tactical superiority: Ensei’s apparent vulnerability is a calculated feint; he abandons Susanoo and escapes before the Tailed Beast Bomb lands.
• Balance among the great villages: The Raikage believes Kumogakure’s defeat will weaken it but not destroy it, while Konoha’s victory may provoke hostility from the other major villages.

Character Interactions

• Ensei and the Eight-Tails engage in a tense negotiation involving the lives of Killer B and Yugito.
• The Fourth Raikage confronts Nara Shikaku after the barrier disappears but chooses surrender instead of attacking him.
• The Raikage orders Killer B to retreat, but B cannot control the Eight-Tails, leading to the destructive attack on Ensei.
• Ensei taunts and pressures the Eight-Tails into giving up one of its tails.
• The chapter ends with Obito unexpectedly grabbing Ensei, interrupting Konoha’s anticipated victory and signaling a new confrontation.

Chapter Summary: “Nagato at the Height of His Power Attacks”

Key Plot Points and Events

• Uchiha Yansheng senses a space-time disturbance and escapes using his limited version of the Flying Raijin. Because he can only teleport to fixed, pre-marked locations, he jumps to the nearest mark beside his damaged Perfect Susanoo.
• He inspects the ocular power sustaining the Susanoo to ensure it has not been tampered with, then releases more stored power and quickly repairs the construct.
• Killer B witnesses the restored Susanoo through the Eight-Tails’ eyes. The Eight-Tails compares Yansheng’s power to that of the Sage of Six Paths, prompting Killer B to question the tailed beast about the Sage, though it refuses to answer.
• Obito recalls how Minato once overwhelmed him and recognizes Yansheng’s use of the Flying Raijin as the reason Yansheng was willing to leave Konoha. Black Zetsu then appears and confirms that everything is ready.
• Black Zetsu summons the Demonic Statue of the Outer Path. The statue immediately attacks Yansheng, seemingly attracted to the ocular power sustaining his artificial Susanoo. Yansheng avoids it by taking to the air, exploiting the statue’s inability to fly.
• Nagato unexpectedly joins the battle, apparently restored by Black Zetsu. His crippled legs have been replaced with a white substance, and he is now capable of wielding the Rinnegan at close to its full potential.
• Nagato uses Universal Pull and then Planetary Devastation, trapping Yansheng and drawing him toward the black sphere. Yansheng destroys the sphere with four chakra blades from his Susanoo.
• Nagato reaches him before he can escape and uses the Preta Path to absorb the chakra forming Yansheng’s Susanoo. Because Yansheng’s construct is only an imitation rather than a true Mangekyō Sharingan Susanoo, it begins to dissolve.
• Yansheng uses a scroll containing Sage Art chakra and unleashes Sage Art: Tiger’s Roar, briefly stunning Nagato. He drops away from the collapsing Susanoo and prepares to escape using the Flying Raijin, ending with a taunting farewell.

Character Developments

• Uchiha Yansheng demonstrates rapid decision-making, strong sealing and space-time skills, and the ability to repair his powerful artificial Susanoo. However, his limitations become clear: he cannot use Flying Raijin fluidly in combat, cannot fly independently, and his Susanoo is vulnerable to chakra absorption.
• Nagato is revealed to have been physically restored by Black Zetsu. With his body repaired, he attacks with far greater speed and power than the previously encountered Six Paths of Pain, posing a serious threat even to Yansheng.
• Obito remains wary of Yansheng because of his connection to Flying Raijin and recalls being nearly defeated by Minato. His envy of Yansheng’s Susanoo also highlights his disadvantage from possessing only one Sharingan.
• Black Zetsu continues manipulating events from behind the scenes, preparing the battlefield, restoring Nagato, and summoning the Demonic Statue.
• Killer B becomes curious about the Sage of Six Paths after hearing the Eight-Tails’ comparison, though the tailed beasts still refuse to reveal their knowledge.

Significant Themes

• Power and imitation: Yansheng’s Susanoo is formidable but artificial, and its differences from the genuine technique leave it vulnerable to Nagato’s absorption abilities.
• Preparation versus instinct: Yansheng survives through planning, marked teleportation, stored chakra, and prepared Sage Art scrolls, while Nagato’s overwhelming attacks leave little time for conventional strategy.
• Manipulation and hidden control: Nagato’s unexpected appearance and restoration suggest that Black Zetsu is altering events and possibly exploiting the restrictions placed on Nagato’s borrowed Rinnegan.
• The legacy of the Sage of Six Paths: The Eight-Tails’ comparison elevates Yansheng’s power while also reinforcing the mystery surrounding the Sage and the tailed beasts’ unwillingness to discuss him.
• Limits of overwhelming strength: Even Yansheng’s massive Susanoo cannot guarantee victory when confronted by an ability specifically suited to absorb chakra.

Character Interactions

• The Eight-Tails praises Yansheng’s power to Killer B, leading B to press it for information about the Sage of Six Paths.
• Obito reflects on Minato while observing Yansheng, linking Yansheng’s Flying Raijin to Obito’s past defeat and fear.
• Black Zetsu informs Obito that the preparations are complete before summoning the Demonic Statue.
• Nagato directly confronts Yansheng, using gravitational techniques and the Preta Path to dismantle his Susanoo.
• Yansheng counters Nagato with his prepared Sage Art and escapes while taunting the assembled enemies.

Chapter Summary: “Escape, Flying Raijin Really Is Useful”

Key Plot Points and Events

• Uchiha Yansheng uses Flying Raijin to appear beside Zero-Two, confirms she is unharmed, and keeps his four artificial humans with him as escorts.
• Black Zetsu locates Yansheng, allowing Obito and Nagato—accompanied by the Demonic Statue of the Outer Path—to track him down.
• Yansheng stalls by taunting them, especially Obito over his fixation on Rin and Yansheng’s creation of Zero-Two in Rin’s image.
• Obito loses control and attacks with Wood Release: Cutting Sprigs Technique, impaling Zero-Two. Her resemblance to Rin momentarily confuses him and successfully distracts him.
• Nagato summons numerous giant beasts. Yansheng sends his other artificial humans to fight them while confronting Nagato directly.
• When Nagato grabs him, Yansheng escapes through a Shadow Clone. The clone leaves behind an explosive container, creating a distraction while Yansheng transforms into a bird and observes from safety.
• A second decoy, disguised as Morino Ibiki, is exposed and killed by Black Zetsu. The real Ibiki is revealed to be a White Zetsu ally in disguise.
• Yansheng immediately abandons his transformation, anticipating that the enemy may detect it. Nagato attempts to use the Human Path to seize his soul, but Yansheng escapes once again.
• Using Flying Raijin, Yansheng ultimately returns to the ruins of the Empty Zone, where he recalls and repairs his four artificial humans.
• He concludes that Nagato has become unexpectedly powerful, likely due to Black Zetsu’s intervention, and begins considering how to strengthen himself and eliminate Black Zetsu.

Character Developments

• Uchiha Yansheng demonstrates increasing reliance on strategy, deception, Shadow Clones, transformations, explosives, and Flying Raijin rather than attempting to overpower Nagato and Obito directly.
• He remains arrogant and provocative, but his internal thoughts reveal genuine caution regarding Nagato’s strength and the danger posed by the Rinnegan’s Human Path.
• Obito is shown to be emotionally unstable regarding Rin. Seeing Zero-Two’s resemblance to her causes him to hesitate briefly, but Yansheng’s insults provoke him into an uncontrolled attack.
• Nagato appears physically healthier and possesses greatly increased chakra reserves, making him a much more dangerous opponent than before.
• Black Zetsu continues to act as a calculating and persistent enemy, apparently manipulating circumstances to enhance Nagato’s power.
• Zero-Two and the other artificial humans serve as combat support and distractions, suffering injuries but surviving through Yansheng’s ability to summon them back.
• Chachamaru complains about his oversized body after gaining Sage Art chakra, adding a humorous contrast to the otherwise dangerous situation.

Significant Themes

• Deception and survival: Yansheng survives through misdirection, decoys, transformations, and teleportation rather than direct combat.
• The power of Flying Raijin: The technique proves invaluable for rapid movement, escape, retrieving allies, and avoiding lethal attacks.
• Emotional manipulation: Yansheng exploits Obito’s grief over Rin, showing how personal trauma can be weaponized in battle.
• Unpredictable power growth: Nagato’s unexpected recovery and increased chakra demonstrate that previous battle assumptions are no longer reliable.
• Creation and identity: Zero-Two’s resemblance to Rin raises questions about artificial beings, imitation, and the emotional consequences of recreating someone who has died.
• Escalating threats: Yansheng recognizes that Black Zetsu’s interference has made Nagato more dangerous and identifies Black Zetsu as a priority target.

Character Interactions

• Yansheng verbally provokes Obito by dismissing Rin’s death and comparing it to the countless other deaths in the world.
• Obito responds with overwhelming violence, attacking Zero-Two because of her resemblance to Rin.
• Yansheng attempts to speak with Nagato but is immediately seized by the throat, prompting him to use a Shadow Clone escape.
• Black Zetsu repeatedly exposes and attacks Yansheng’s decoys, while White Zetsu humorously mocks Black Zetsu after one deception fails.
• Yansheng repairs and discusses the condition of his artificial humans, while Chachamaru asks him to help reduce his oversized form.

Chapter Summary: “Opening the Mangekyo Sharingan Experiment... Failed!”

Key Plot Points and Events

• After notifying Fugaku Uchiha of his safety, Uchiha Yansheng returns to the ruins of the Empty Zone to conduct a strength-enhancement experiment.
• He identifies Nagato—possibly enhanced with White Zetsu cells and influenced by Kotoamatsukami—as one of his greatest potential enemies. Nagato’s Rinnegan is especially dangerous because it can counter Yansheng’s reliance on overwhelming ocular power.
• Concluding that awakening the Mangekyo Sharingan would be the safest way to strengthen himself, Yansheng begins preparing:
  • He cultivates Three-Tomoe Sharingan using Hashirama Cell culture mediums.
  • He attempts to grow a fragment of the Demonic Statue of the Outer Path, which he previously severed using Flying Raijin.
  • He creates a White Zetsu outer shell enhanced with Hashirama Cells to provide temporary, powerful regenerative abilities.
• Because Yansheng lacks the emotional trauma, treasured relationships, or Kotoamatsukami assistance that helped other Uchiha awaken advanced Sharingan, he chooses extreme anger as the emotional trigger.
• He seals chakra taken from Itachi’s brain into his Sharingan and prepares multiple safeguards, including Izanagi sealed into a spare Three-Tomoe Sharingan.
• He injects himself with anger-inducing and paralysis drugs, then dons the Hashirama-enhanced White Zetsu shell.
• The paralysis takes effect before the anger drug appears to work. However, a sudden surge of rage eventually activates the sealed chakra in his eyes.
• Yansheng loses mental control during the process, nearly risking the accidental release of his most dangerous techniques.
• Three months later, he exits the laboratory and reveals that the Mangekyo awakening experiment failed—but that the failure unexpectedly led to an even better discovery.

Character Developments

• Uchiha Yansheng: Becomes increasingly focused on long-term preparation and scientific experimentation to overcome threats such as Nagato. He demonstrates extreme caution by preparing Izanagi as a failsafe, while also showing his willingness to risk his life in pursuit of greater power. His emotional detachment makes awakening the Mangekyo especially difficult.
• Nagato: Although absent from the chapter, he is established as a major threat. His possible physical enhancement and mental manipulation make him a dangerous counter to Yansheng.
• Chachamaru: Guards the laboratory for three months, though Yansheng recognizes that his concern is largely motivated by hopes of gaining access to Sage Art research involving female Ninja Cats.
• Cat Granny: Continues to restrict Sage Art experimentation, leaving Chachamaru as the only Ninja Cat capable of using Sage Art chakra.

Significant Themes

• The pursuit and cost of power: Yansheng continually seeks stronger abilities, but every method carries severe physical, mental, or strategic risks.
• Science versus natural talent: Rather than awakening the Mangekyo through personal tragedy, Yansheng relies on genetic modification, drugs, chakra manipulation, and biological experimentation.
• Preparation and contingency planning: His use of Izanagi, spare Sharingan, regenerative tissue, and Flying Raijin reflects his belief that no experiment should proceed without a means of survival.
• The danger of emotional manipulation: Yansheng attempts to manufacture the intense emotion traditionally associated with Mangekyo awakening, but the resulting rage threatens his control and judgment.
• Failure as discovery: Although the stated experiment fails, the outcome suggests that unintended results may produce a more valuable advancement.

Character Interactions

• Yansheng sends a Ninja Cat to reassure Fugaku Uchiha that he is safe.
• His plans are shaped by the threat posed by Nagato and the Rinnegan.
• Chachamaru waits outside the laboratory and questions him after the experiment, primarily hoping to benefit from Yansheng’s Sage Art research.
• Yansheng’s final statement to Chachamaru establishes a cliffhanger: the Mangekyo experiment failed, but it produced an unforeseen and potentially superior result.

Chapter Summary

Key Plot Points and Events

• Uchiha Ensei’s attempt to awaken the Mangekyō Sharingan fails. The rage stimulus and chakra extracted from Itachi’s brain have no effect, possibly because Izanagi and its Transcription Seal altered the event into an illusion.
• He shifts focus to recreating the Tenseigan. Rather than replacing his eyes with cloned Byakugan, he plans to seal the ocular power of 100,000 Byakugan within his body and use it to purify specially cloned eyes.
• After cloning 100 pairs of Hinata’s Byakugan, only six survive the purification process. Two retain their Byakugan form and appear noticeably more powerful or pure, while the others mutate.
• During the experiments, the Divine Tree fragment in Ensei’s possession mutates under the influence of his chakra and Natural Energy. The resulting white substance resembles Ōtsutsuki flesh and may be related to the Ten-Tails or a Divine Tree seed.
• Ensei researches the substance for over a month and confirms that it absorbs chakra and Natural Energy, grows continuously, and can nourish its host. He names it the “Little Ten-Tails.”
• The Little Ten-Tails’ evolutionary chakra transforms basic One-Tomoe Sharingan into two Mangekyō Sharingan. The eyes originate from the Kamui and Kotoamatsukami abilities, while Itachi’s ocular power is discarded as less practical.
• The Little Ten-Tails grows to over three meters and eventually requires Natural Energy and the Byakugan power stored within Ensei to continue developing. Instead of producing Chakra Fruits, it releases an energy that causes nearby objects to evolve.
• Having achieved the Mangekyō Sharingan, Ensei could return, but he chooses to risk using the Little Ten-Tails to evolve himself toward Ōtsutsuki-level abilities.
• To protect his original body, he prepares a replacement vessel. He combines his own cells with Hyuga cells, implants one of the two special Byakugan pairs, uses the Spirit Transformation Technique, and transfers his consciousness into the new body.

Character Development

• Uchiha Ensei becomes increasingly experimental and ambitious. His failed Mangekyō plan does not discourage him; instead, he adapts through increasingly dangerous biological and chakra-based research.
• He demonstrates greater caution by creating a backup body before attempting personal evolution, showing that his ambition is balanced by practical contingency planning.
• His discovery of the Little Ten-Tails strengthens his confidence and raises his goals from merely acquiring the Mangekyō Sharingan to obtaining power comparable to the Ōtsutsuki Clan.

Significant Themes

• Experimentation and adaptation: Ensei repeatedly abandons failed methods and develops new approaches.
• The limits of artificial power: Cloned eyes and manipulated chakra prove unreliable, while the mutated Ten-Tails-like organism offers a more successful route.
• Evolution through forbidden means: The Little Ten-Tails represents artificial biological evolution and the dangerous pursuit of Ōtsutsuki-like abilities.
• Risk versus survival: Ensei is willing to gamble his body and identity for greater power, but only after preparing a backup vessel.
• Identity and transformation: The creation of new bodies, transplanted eyes, and evolving flesh raises questions about what remains of Ensei as he changes himself.

Character Interactions

• Ensei’s primary “interactions” are with the biological materials and powers he manipulates: cloned Byakugan, Uchiha ocular abilities, Hyuga cells, Natural Energy, and the Divine Tree fragment.
• His connection to the Little Ten-Tails evolves from experimentation to a form of mutual dependence: Ensei feeds it chakra and Natural Energy, while it nourishes him and grants evolutionary power.
• The chapter also indirectly involves Itachi, Shisui, Kakashi, Hinata, and the Hyuga and Ōtsutsuki clans through their genetic material, eye techniques, and biological legacy.

Chapter Summary: “Scheming for the Power of the Dragon Vein”

Key Plot Points and Events

• Uchiha Ensei tests the Spirit Transformation Technique by transferring his soul into a specially created clone. He confirms that the technique resembles body-snatching but is not true reincarnation: his soul remains connected to his original body, and the clone eventually begins rejecting it.
• He discovers that the technique’s duration depends on the amount of chakra carried by his soul. When the chakra runs out, both the original body and the clone attempt to draw his soul back, forcing him to choose. He ultimately returns safely to his original body.
• Ensei continues experimenting with the clone and activates its Byakugan, confirming that the earlier lack of visible strain was because the Byakugan in his original body had absorbed the activation burden.
• He draws ocular power from the enormous supply of Byakugan sealed within his body to nourish the clone’s eyes, hoping to evolve them into a Tenseigan. Although the evolution begins, it soon slows, possibly because he lacks chakra from Hamura Ōtsutsuki’s lineage.
• Ensei uses the clone’s partially awakened Tenseigan abilities to control its body like a puppet. He then merges the clone into the Little Ten-Tails and continues his experiments with additional Byakugan.
• After visiting the Cat Ninja Village and receiving intelligence and a map from Cat Granny, Ensei travels to the ruins of Rōran, abandoning his promised Natural Energy research with Chachamaru for the time being.
• Using the Byakugan, he locates the Dragon Vein Seal beneath a Flying Raijin kunai. He carefully opens a small gap in the seal, wary of the Dragon Vein’s ability to affect space and time.
• Ensei releases the Little Ten-Tails, which instinctively attempts to absorb the Dragon Vein’s leaking power. Ensei orders it to stop, testing his control over it. The creature obeys immediately despite its eagerness.

Character Developments

• Uchiha Ensei becomes increasingly focused on acquiring overwhelming power and preparing for future enemies, aiming eventually to reach a level comparable to a Ten-Tails jinchūriki.
• His experiments show his growing understanding of the relationship between souls, bodies, chakra, and ocular powers. He accepts the instability of his clone-body possession and considers simply changing bodies periodically if necessary.
• Ensei’s ambition expands toward obtaining the Tenseigan, even though he recognizes its limitations compared with the Rinnegan. His desire for strength outweighs concerns about long-term risks.
• He also confirms his authority over the Little Ten-Tails, demonstrating that it will obey direct commands even when its instincts urge it to act otherwise.

Significant Themes

• Power through experimentation: Ensei treats his body, soul, clones, and the Ten-Tails as subjects of systematic experimentation.
• Compatibility of soul and flesh: The chapter explores the tension between spiritual identity and physical vessels, presenting body possession as a process limited by chakra and rejection.
• Ambition and preparedness: Ensei’s pursuit of the Tenseigan reflects his fear of powerful future enemies and his willingness to pursue dangerous abilities for security.
• Control versus instinct: The Little Ten-Tails’ hunger for Dragon Vein energy contrasts with Ensei’s authority, emphasizing the struggle between natural impulse and imposed control.
• The destructive potential of chakra: Ensei reflects that chakra has allowed great civilizations to develop but has also made the Ninja World’s native civilizations vulnerable to sudden destruction.
• Time and forbidden power: The Dragon Vein’s connection to space-time recalls the possibility of time travel and introduces a potentially dangerous new source of power.

Character Interactions

• Ensei interacts with his clone, using Spirit Transformation and testing whether his soul can control and remain within another body.
• He communicates with the Little Ten-Tails, first allowing it to merge with the clone and later testing whether it will obey a direct command.
• He visits Cat Granny at the Cat Ninja Village to exchange information and obtain directions to Sunagakure and Rōran.
• Although not physically present, Chachamaru is relevant through Ensei’s postponed promise to research Natural Energy.
• The chapter also alludes to Naruto’s possible past time-travel incident and to figures such as Toneri and Kaguya, which shape Ensei’s expectations and plans for future power.

Chapter Summary: “Tenseigan Successfully Synthesized”

Key Plot Points and Events

• Uchiha Ensei prepares the underground chamber containing the obedient Little Ten-Tails by constructing a powerful barrier and placing numerous Flying Thunder God marks.
• He deploys four artificial human puppets, several of which contain Tailed Beast chakra, and installs additional defenses, including the Four Red Yang Formation, explosives, Exploding Flies, Patrick Star, and other technology.
• To ensure the Little Ten-Tails remains controllable, Ensei extracts and seals away a fragment of its body, marks it with hundreds of Flying Thunder God seals, and embeds a Flying Thunder God Kunai inside it.
• After confirming that the creature will not absorb Natural Energy without permission, Ensei allows it to draw power from the leaking Dragon Vein Seal.
• While replenishing supplies in the Land of Fire, Ensei detects White Zetsu hiding underground. He deliberately allows them to approach before capturing several, while making the incident appear accidental. He then conceals one of the captured White Zetsu in his laboratory and notices that Konoha’s forces have searched the facility.
• Ensei returns to the Rōran Ruins and orders the Little Ten-Tails to absorb only the Natural Energy leaking from the Dragon Vein Seal.
• He places two cloned bodies containing Byakugan and Hyuga bloodlines inside the Little Ten-Tails and continuously feeds them ocular power from the vast number of Byakugan sealed within his body.
• After several months, the third gestation successfully produces the Tenseigan. Ensei uses the Spirit Transformation Technique to enter the new bodies and test their abilities.
• The Tenseigan proves comparable to the Rinnegan, with some advantages such as the ability to create Truth-Seeking Orbs and absorb chakra from a distance. However, its stamina is more limited, and it must rely on stored or external chakra to recover.
• Ensei discovers that he can remain in another body for months through the Spirit Transformation Technique, though he still considers his original body essential.
• He has the Little Ten-Tails consume and cultivate his original body, hoping to enhance it with Ōtsutsuki-level potential. He also adds two Mangekyō Sharingan, hoping they will develop abilities such as Kamui or Kotoamatsukami.
• After transferring himself into the Tenseigan body he intends to use for the next several years, Ensei leaves the other body with the Little Ten-Tails and prepares to return to Konoha.

Character Development

• Uchiha Ensei becomes even more cautious and strategically minded. Although he begins trusting the Little Ten-Tails, he continues taking precautions by installing seals, barriers, tracking marks, and emergency defenses.
• He demonstrates increasing confidence in manipulating enemies and information, particularly when he intentionally baits and captures the White Zetsu while concealing his true capabilities.
• Ensei’s ambitions expand beyond simply creating the Tenseigan. He now seeks to optimize his body, combine various bloodlines and eye powers, and potentially achieve Ōtsutsuki-level talent.
• The Little Ten-Tails develops as a cooperative and obedient experimental partner. Its restraint—refusing to consume Natural Energy until instructed—convinces Ensei that it can be trusted, at least provisionally.

Significant Themes

• Control versus trust: Ensei relies on the Little Ten-Tails but surrounds it with safeguards, reflecting the difficulty of trusting a powerful artificial creature.
• Scientific experimentation and bodily transformation: The chapter focuses on cultivating bloodlines, synthesizing the Tenseigan, transferring souls, and modifying bodies.
• Power and limitations: Although the Tenseigan reaches Rinnegan-level strength, its weaker endurance shows that superior power comes with trade-offs.
• Preparation and paranoia: Ensei constantly plans for betrayal, invasion, and failure, emphasizing his survival-oriented mindset.
• The pursuit of transcendence: By combining Byakugan, Mangekyō Sharingan, Natural Energy, and Ten-Tails biology, Ensei seeks to surpass normal shinobi and approach the power of the Ōtsutsuki.

Character Interactions

• Ensei maintains a cautious partnership with the Little Ten-Tails, giving it precise instructions about where and how to absorb Natural Energy.
• He uses the creature as a cultivation vessel for the Byakugan-based clones and later sacrifices his own body to its development.
• His encounter with the White Zetsu is indirect but highly calculated: he deceives them into approaching and captures several before the remainder escapes.
• The discovery that Konoha searched his laboratory suggests growing tension between Ensei and Konoha, though he avoids direct confrontation and secretly relocates his resources.
• Ensei’s relationship with his own bodies becomes increasingly complex, as he treats them simultaneously as vessels, experiments, weapons, and potential paths toward greater power.

Chapter Summary: “But Unfortunately, I Don’t Trust You”

Key Plot Points and Events

• Before leaving the Rōran Ruins, Uchiha Ensei investigates the remaining Rōran survivors, particularly Sara, the former queen and the only person capable of sensing or partially controlling the Dragon Vein Seal.
• He summons the ninja cat Hina to obtain information from Cat Granny about the survivors’ location. He also dismisses Chachamaru’s request for help researching Natural Energy, prioritizing his ongoing Tenseigan and Little Ten-Tails research.
• Ensei finds the survivors living safely near the Land of Fire, under Konoha’s protection. Sara is managing the village’s finances when he approaches her.
• Using his Byakugan and genjutsu, Ensei shows Sara visions of future wars involving the Allied Shinobi Forces and the Ten-Tails. He claims he needs the Dragon Vein to oppose a powerful enemy and insists that he has already ensured its power will not harm anyone.
• Sara initially distrusts him, associating his behavior with Mukade, the rogue ninja who previously exploited Rōran and caused its downfall. She pretends to cooperate while expecting Konoha to intervene.
• Ensei recognizes her suspicion and admits that killing her would be the simplest way to prevent interference, though he claims he avoids killing unless necessary. He explains that the Dragon Vein may possess dangerous, time-related power and that Sara’s ability to control it makes her a potential threat.
• To prove his claims, Ensei uses Flying Thunder God to take Sara directly to the Dragon Vein’s underground chamber. After sensing the seal and finding no immediate leak, Sara agrees not to interfere.
• Ensei nevertheless reveals that he does not trust her. He places her under a genjutsu and creates a duplicate body with Sharingan-like eyes, apparently establishing a protective or monitoring connection.
• The next day, Sara believes the encounter may have been a dream until she discovers a marked kunai beside her bed. The Flying Thunder God mark confirms that Ensei’s visit was real and allows him to reach her if she is endangered.

Character Developments

• Uchiha Ensei: Demonstrates caution, strategic thinking, and a willingness to manipulate others to protect his plans. Although he presents himself as being on the “good” side, he openly considers killing Sara and ultimately uses genjutsu without her consent. His concern about hidden powers in the Ninja World shows increasing awareness of the dangers surrounding the Dragon Vein.
• Sara: Displays competence and vigilance as leader of the Rōran survivors. She remains deeply wary because of Rōran’s past exploitation, but her concern for the Dragon Vein forces her to investigate Ensei’s claims. She agrees not to interfere, though her trust remains uncertain.
• Hina and the ninja cats: Serve as Ensei’s information network and remind him of his connections to Cat Granny and Chachamaru, though Ensei remains impatient with their requests.

Significant Themes

• Trust and distrust: The chapter centers on the mutual suspicion between Ensei and Sara. Neither fully believes the other, and their cooperation is based on necessity rather than confidence.
• Power and responsibility: The Dragon Vein represents immense, potentially world-altering power. Ensei believes controlling it is necessary to stop greater threats, but his methods raise questions about whether he can be trusted with such power.
• Manipulation versus protection: Ensei claims to protect Sara by placing her under genjutsu and marking her with a Flying Thunder God kunai, but he does so without her consent. The same act can be interpreted as either safeguarding her or controlling her.
• The burden of leadership: Sara’s work managing the survivors’ village and protecting Rōran’s legacy contrasts with Ensei’s larger concerns about future wars and supernatural forces.

Important Character Interactions

• Ensei and Hina: Ensei uses Hina to gather intelligence and rejects Chachamaru’s request for assistance, emphasizing his current priorities.
• Ensei and Sara: Their interaction evolves from confrontation to reluctant cooperation. Ensei explains his plans and demonstrates the Dragon Vein’s situation, while Sara tests whether he is telling the truth.
• Ensei and the Dragon Vein: Ensei treats the Dragon Vein as a dangerous strategic resource that must be controlled before it can threaten others.

Chapter Summary: Izanami That Lasted Two Years

Key Plot Points and Events

• Uchiha Ensei returns to Konoha after disappearing for two years. At the village gate, guards Izumo Kamizuki and Kotetsu Hagane sense his overwhelming presence and initially prepare for trouble.
• Ensei identifies himself as a returning Konoha special jonin. Hiruzen Sarutobi arrives personally to confirm his identity, having detected him through Konoha’s barrier.
• Ensei refuses to discuss what happened during his disappearance and heads directly toward the Uchiha compound. His dismissive attitude reminds the gate guards of his old arrogant reputation.
• News of his return spreads rapidly. Sasuke Uchiha rushes to him and begs for help, explaining that his older brother Itachi has never awakened from the attempt to awaken his Mangekyō Sharingan.
• Ensei realizes that Itachi has remained trapped in the Izanami genjutsu he cast more than two years earlier. The technique forced Itachi to repeatedly experience horrific visions involving the massacre of the Uchiha clan, the deaths of his parents, and Sasuke’s death.
• Fugaku initially explains that Izanami should release its victim once they accept their true nature. However, Ensei admits that he accidentally modified the technique, potentially leaving Itachi trapped indefinitely.
• Although shocked, Fugaku accepts responsibility for the consequences, arguing that the clan chose the dangerous shortcut of awakening the Mangekyō Sharingan and must bear the resulting price.
• Ensei releases Itachi by sending chakra into his eyes and undoing the Izanami. Itachi awakens seemingly emotionless, then looks at Ensei with his Mangekyō Sharingan and thanks him.

Character Developments

• Uchiha Ensei: Returns more powerful and self-assured, remaining blunt and dismissive toward authority. Despite claiming not to care about Itachi, he feels genuine embarrassment and guilt over accidentally trapping him for two years. His actions reveal that he is willing to correct his mistakes.
• Hiruzen Sarutobi: Personally verifies Ensei’s return and reacts with relief and complicated emotions. Ensei’s refusal to acknowledge him reminds Hiruzen that he can no longer easily control or command him.
• Fugaku Uchiha: Demonstrates composure and responsibility as clan head. Though disturbed by what happened to Itachi, he accepts that the clan’s pursuit of power created the situation and allows Ensei to attempt the rescue.
• Itachi Uchiha: Has endured severe psychological torment within Izanami and awakens emotionally vacant. His first clear action is to thank Ensei, suggesting maturity, gratitude, and perhaps a changed perspective.

• Izumo and Kotetsu: Initially fear Ensei as an overwhelming threat but quickly recognize him as the famous Uchiha hero. Their reaction also emphasizes Ensei’s intimidating reputation.

Significant Themes

• The consequences of seeking power: The Uchiha’s attempt to awaken the Mangekyō Sharingan through experimentation leads to Itachi’s prolonged suffering.
• Responsibility and accepting consequences: Fugaku argues that choices made by the clan must be paid for, while Ensei is forced to confront the unintended consequences of his own technique.
• Appearance versus reality: Ensei appears polite upon returning, but his familiar arrogance quickly resurfaces. Similarly, Izanami is intended as a corrective or saving technique, yet Ensei’s modification turns it into prolonged torment.
• Guilt beneath indifference: Ensei insists that he dislikes Itachi and does not care deeply about him, but his discomfort and immediate effort to free him reveal hidden concern.
• Psychological transformation: Itachi’s repeated exposure to death and betrayal may have fundamentally changed him, and his quiet gratitude hints at the impact of the two-year ordeal.

Important Character Interactions

• Ensei calmly challenges the gate guards and ignores Hiruzen’s authority, reinforcing his independence.
• Sasuke appeals directly to Ensei as the only person capable of saving Itachi.
• Fugaku confronts Ensei about the implications of Izanami and ultimately gives him permission to release Itachi.

Chapter Summary: Minato Namikaze Awakens

Key Plot Points and Events

• Itachi Uchiha awakens after spending two years unconscious and reveals that he has finally confronted the truth that tormented him. He admits that his arrogance—not merely the Uchiha Clan’s pride—was responsible for his mistakes.
• Uchiha Ensei feels uneasy about Itachi’s recovery, since Itachi’s mental revelations were caused by Ensei’s use of Izanami. He quickly leaves rather than continue the awkward conversation.

• Ensei reflects cynically on Hiruzen Sarutobi’s political strategy, recognizing that Hiruzen has neutralized the Uchiha through diplomacy rather than open conflict.
• He resumes work in his laboratory after more than two years of inactivity. His main research subjects are flesh taken from the Little Ten-Tails and a captured White Zetsu.
• After several days, Ensei concludes that both specimens are beyond his current scientific ability to analyze. He decides to improve his skills by studying under Tsunade, while postponing any dealings with Orochimaru.
• Ensei visits Kushina Uzumaki and discovers that Minato Namikaze has awakened. Minato has been conscious for less than a month but remains weakened because the dark power inside him has not been fully removed.

Character Developments

• Itachi Uchiha: Emerges from his prolonged unconscious state with a changed perspective. He recognizes his own arrogance and appears emotionally scarred but mentally clearer.
• Uchiha Ensei: Remains detached and opportunistic.

• Identity and detachment: Ensei views his body as expendable and considers only his soul truly his own, reinforcing his alienation from ordinary human attachments.
• Limits of knowledge: His failure to analyze the Ten-Tails tissue and White Zetsu pushes him toward formal learning and collaboration with stronger experts.

Character Interactions

• Itachi and Ensei: Itachi thanks or acknowledges Ensei’s role in forcing him to confront his flaws, while Ensei becomes uncomfortable and quickly withdraws.
• Mikoto and Itachi: Mikoto anxiously checks on her son, demonstrating maternal concern despite not understanding what happened to him.

Chapter Summary: “Black Zetsu’s Chakra”

Key Plot Points and Events

• After speaking with Minato and Kushina, Ensei agrees to investigate the dark energy corrupting Minato’s body, suspecting it is Black Zetsu’s chakra.

• Ensei activates his unstable Tenseigan Chakra Mode and uses its chakra to suppress Minato’s own chakra and take control of his body.
• He examines Minato’s internal condition and successfully extracts a small strand of intensely malicious black chakra.
• Ensei seals the chakra inside a Three-Tomoe Sharingan containing Izanagi, clearly intending to study or contain it despite Minato’s concerns.
• Ensei explains that he can gradually remove the remaining corruption, but the process would take several years if performed three times a day.
• He proposes taking Minato to Tsunade, believing she can help now that Minato’s consciousness has awakened.
• The chapter ends with Ensei asking how Minato regained consciousness, leaving the mystery of his awakening unresolved.

Character Developments

• Minato Namikaze: Shows trust in Ensei by allowing him to control his body without resistance. Despite being weakened, he remains knowledgeable and perceptive, questioning Ensei’s use of a Sharingan and Izanagi.
• Kushina Uzumaki: Remains deeply protective and anxious about Minato. Her efforts to become a medical ninja for his sake are emphasized, as is her continuing relationship with Kurama.
• Kurama: Senses that Ensei’s chakra is extraordinarily powerful—possibly approaching the Sage of Six Paths’ level—and briefly wonders whether Ensei may be connected to the Sage’s prophecy. He also hints at forgotten knowledge about the chakra.
• Black Zetsu: Though absent, he becomes more threatening through discussion of his history, hidden strength, and lingering chakra inside Minato.

Significant Themes

• Trust and cooperation: Minato must trust Ensei enough to surrender control of his body, while Kushina relies on Ensei to save her husband.
• Hidden threats and vigilance: Black Zetsu’s deceptive nature reinforces the need for extreme caution and decisive action.
• Power and instability: Ensei’s new Tenseigan ability is powerful but not yet stable, suggesting potential risks in using it.

• Ensei invites Minato to meet Tsunade, creating a possible path toward both Minato’s recovery and Ensei’s own medical training.

Chapter Summary: Going to Tsunade for Treatment

Key Plot Points and Events

• Minato Namikaze awakens from his long-term coma after sensing Kushina Uzumaki’s chakra. Kushina hides the fact that she kissed him awake, while Minato explains that her presence helped him escape the nightmare.
• Uchiha Ensei analyzes Minato’s recovery and suggests two possibilities: Black Zetsu’s technique weakened over time, or Kurama somehow helped awaken him.
• Kushina reveals that Kurama once tried to transmit her longing to Minato, though he was unsure whether it worked. Ensei concludes that Black Zetsu’s influence most likely weakened naturally.
• Minato recounts the original incident. After severely injuring Obito, he was ambushed by Black Zetsu. Minato escaped using the Flying Thunder God, but afterward discovered that his chakra had been disrupted and soon fell unconscious.
• Ensei realizes that Minato may not have been deliberately placed under a long-term technique. Instead, part of Black Zetsu’s unusual chakra may have remained inside Minato after the attack, causing his body to reject it and forcing him into a coma.
• Minato proposes that Black Zetsu may be a special chakra-based life-form, similar in nature to a tailed beast. Ensei agrees and suggests that sealing the foreign chakra might cure Minato, although the technique would need to be as powerful as the Reaper Death Seal.
• The group reflects on how Minato’s coma resulted from an unforeseen consequence of the battle, as well as Ensei’s failed plan to have Hiruzen use the Reaper Death Seal during the Nine-Tails crisis.
• Ensei decides that Minato must be taken to Tsunade for treatment and orders Kushina to prepare and send Tsunade a letter.

Character Developments

• Minato regains consciousness and begins reconstructing the events that caused his condition. He demonstrates clear judgment by recognizing that Black Zetsu’s chakra may be responsible.
• Kushina becomes more emotionally open and visibly devoted to Minato. Her connection with Kurama has developed rapidly, and her chakra may have played a role in Minato’s awakening.

• Kurama is portrayed as having formed an unexpectedly cooperative relationship with Kushina, even attempting to communicate her feelings to Minato.
• Black Zetsu is revealed to have left behind dangerous, abnormal chakra, though his exact intentions and abilities remain uncertain.

Significant Themes

• Love and emotional connection: Kushina’s bond with Minato and Kurama’s attempt to convey her feelings suggest that emotional attachment can influence even severe supernatural conditions.
• Unintended consequences: Minato’s coma may have been an accidental result of injuring Black Zetsu rather than a deliberate technique, showing how battles can produce unforeseen outcomes.
• Sealing and sacrifice: The Reaper Death Seal represents the extreme measures required to counter powerful chakra and recalls the sacrifices made during the Nine-Tails attack.
• Changing fate: Ensei’s plans to protect Minato and alter Konoha’s future have partially succeeded, though unexpected events continue to disrupt them.
• Political criticism and responsibility: Ensei harshly condemns Hiruzen’s indecisiveness and contrasts it with Minato’s willingness to act decisively.

Character Interactions

• Kushina and Minato share an intimate, emotionally charged reunion, with Kushina embarrassed about how she awakened him.
• Ensei questions both of them directly, forcing Minato to revisit the traumatic battle with Obito and Black Zetsu.

• She suddenly recognizes Ensei as the person who awakened a Mangekyō ability capable of seeing the past and future.

Character Developments

• Tsunade: Her gambling behavior and apparent resignation to her cursed luck reveal her emotional withdrawal from her former ninja life. However, her intense reaction to Dan and Nawaki’s names shows that their deaths remain a deep emotional wound. She also demonstrates that, despite her older age and disillusionment, she retains extraordinary physical power and combat instincts.
• Uchiha Ensei: He is established as a powerful, unconventional researcher with advanced knowledge of cloning and resurrection. He is confident enough to provoke Tsunade and capable of matching her in battle, though his blunt remarks worsen the situation.

• The chapter ends with Tsunade recognizing Ensei’s connection to the mysterious Mangekyō ability that can perceive the past and future.

Chapter Summary: “No, I Agree.”

Key Plot Points and Events

• Uchiha Ensei reveals that he knows two possible methods of resurrection and offers this information to Tsunade in exchange for her medical assistance.
• Tsunade initially becomes hopeful, then realizes Ensei is likely referring to forbidden techniques involving the dead, particularly Impure World Reincarnation. After reflecting on the possibility of seeing her loved ones again, she decisively agrees to help.
• Ensei explains the first method: Chiyo’s forbidden technique, One’s Own Life Reincarnation. Developed for Sasori, it can restore life to someone who has only recently died, but it requires the user to sacrifice their own life. Ensei clarifies that this is closer to an advanced revival or healing technique than true resurrection.
• He then explains the second method: the Rinnegan’s power to revive the dead, which Tsunade has encountered through one of Jiraiya’s former disciples in Amegakure. However, the eyes belonged to Madara Uchiha, and using their resurrection ability would require an unknown and potentially fatal amount of life force.
• Tsunade questions Ensei about Madara and the Infinite Tsukuyomi, realizing that she has missed important intelligence during her years of isolation.
• Tsunade agrees to assist Ensei and treat Minato Namikaze, but she refuses to return to Konoha. She resumes her former life of drinking, gambling, and wandering, though her agreement reveals that hope has begun to return.
• Several days later, Tsunade proposes establishing a laboratory. Ensei transports her and Minato to laboratories he prepared in the ruins of the Empty Zone near the Cat Ninja Village.
• Shizune is sent to accompany Kushina, while Ensei begins working closely with Tsunade and repeatedly consults her about medical and experimental matters. When Tsunade lacks answers, she directs him toward books in the Konoha Library.

Character Developments

• Tsunade: Moves from guarded despair to cautious hope. Although she maintains her self-destructive lifestyle and continues refusing to return to Konoha, she chooses to help Ensei and Minato, suggesting that she is not truly indifferent or beyond recovery.
• Uchiha Ensei: Demonstrates strategic manipulation by using knowledge of resurrection as leverage to gain Tsunade’s cooperation. He is also pragmatic, dispelling his Tenseigan Chakra Mode to conserve chakra and focusing on creating the conditions necessary for his experiments.
• Minato Namikaze: Remains largely silent but becomes directly involved in Tsunade’s decision, since her assistance will also allow her to treat him.
• Shizune: Is temporarily separated from Tsunade and assigned to keep Kushina company, despite being repeatedly overlooked.
• Hiruzen Sarutobi: Is criticized by Ensei for leaking information about Ensei’s abilities while apparently failing to remember or reveal his name accurately.
• Madara Uchiha: Is established as a continuing threat whose preparations and plans extend beyond death.

Significant Themes

• Hope emerging from despair: Tsunade’s agreement marks the return of a small but meaningful hope after years of grief and avoidance.
• The morality and cost of resurrection: Both methods require disturbing natural death or sacrificing life, raising questions about whether revival is worth its price.
• Knowledge as power: Ensei uses rare information about forbidden techniques, Madara, and the Rinnegan to influence Tsunade and secure her cooperation.
• Trauma and avoidance: Tsunade’s refusal to return to Konoha and her continued gambling and drinking show that she still avoids painful memories and people associated with them.
• Life, death, and sacrifice: The chapter contrasts genuine resurrection with temporary revival and emphasizes that restoring life always demands an enormous cost.

Character Interactions

• Ensei and Tsunade negotiate directly, with Ensei offering resurrection knowledge in exchange for medical aid.
• Tsunade challenges Ensei’s claims and identifies Impure World Reincarnation as the likely method behind his promise to let her see the dead.

• Tsunade asks Ensei for further intelligence about Madara and the Infinite Tsukuyomi, shifting their relationship from a negotiation toward cooperation.
• Tsunade agrees to treat Minato and work with Ensei in a new laboratory, while still maintaining her distance from Konoha.

Chapter Summary: “Don’t Judge Me by Your Standards”

Key Plot Points and Events

• Tsunade becomes involved in Uchiha Ensei’s experiments and is horrified by his work involving human experimentation, cloning bodies, and the replication of Kekkei Genkai.
• She confronts Ensei, questioning his morality and view of life. Ensei reacts angrily, warning her that she has no right to judge him and telling her to leave if she refuses to help.
• Realizing that she has misunderstood him and risked damaging their cooperation, Tsunade consults Minato Namikaze about Ensei’s history.
• Minato explains enough of Ensei’s past for Tsunade to understand that he has been struggling to survive from a very young age. She also recognizes the danger that he could become another Orochimaru, though he still retains certain moral limits.
• Tsunade becomes especially alarmed by Ensei’s cloning technology, which could potentially create an army of shinobi if sufficient resources were available.
• Ensei insists that his experiments are necessary because he is preparing for a future catastrophe in which Madara Uchiha becomes the Ten-Tails’ jinchūriki and threatens the entire world.
• To prove the seriousness of the threat, Ensei activates his partially completed Tenseigan and uses it to seal Tsunade’s chakra and control her body like a puppet.
• He explains that the Tenseigan can drain an opponent’s chakra and control them through physical contact, though it is still inferior to the Rinnegan in some respects.
• Tsunade realizes that Ensei’s current abilities would be useless against the future Madara, who reaches the level of the Sage of Six Paths.
• Ensei argues that foreknowledge of this future is the only reason he has survived and that Tsunade should not judge him by ordinary moral standards.

Character Developments

• Uchiha Ensei: Revealed as deeply pragmatic, defensive, and willing to pursue disturbing experiments in order to survive. His anger comes from years of hardship and the burden of knowing about a future catastrophe. Despite his ruthless methods, he retains some boundaries and does not experiment merely for pleasure or ambition.

• Minato Namikaze: Serves as the source of information that helps Tsunade reassess Ensei and recognize the reasons behind his extreme behavior.
• Madara Uchiha: Though absent, he is established as the future existential threat Ensei is preparing to face.

Significant Themes

• Survival versus morality: Ensei believes extreme circumstances justify dangerous research, while Tsunade initially evaluates him according to conventional ethical standards.
• The burden of foreknowledge: Knowing about a catastrophic future gives Ensei hope but also isolates and distorts him, forcing him to prepare for threats others cannot imagine.
• Power and vulnerability: The Tenseigan demonstration shows how quickly even a powerful shinobi like Tsunade can be rendered helpless.
• Fear of becoming a monster: Tsunade worries Ensei may follow Orochimaru’s path, while Ensei insists that his motives and remaining limits distinguish him from true nihilistic cruelty.
• Isolation and alienation: Ensei’s closing remarks reveal his resentment toward the world he has been forced to inhabit and the hopeless circumstances surrounding him.

Character Interactions

• Tsunade and Ensei clash over the ethics of his experiments, nearly damaging their cooperation.
• After speaking with Minato, Tsunade returns and attempts a gentler approach, warning Ensei that his research is dangerous.
• Ensei responds by demonstrating the Tenseigan directly on Tsunade, forcing her to experience the helplessness he fears facing in the future.
• Their relationship shifts from open moral confrontation toward uneasy understanding: Tsunade remains disturbed by Ensei’s methods, but she begins to recognize that his actions are driven by fear, survival, and preparation rather than simple cruelty.

Chapter Summary: “Soul Changes Are Irreversible”

Key Plot Points and Events

• Ensei realizes that modern medical practices could have saved Tsunade’s former lover, Dan Katō, by controlling internal bleeding, sustaining his vital functions, and replacing damaged organs.
• After learning that internal organs can potentially be repaired or replaced, Tsunade disappears for three days. When she returns, her hemophobia has completely vanished, suggesting she has emotionally confronted or reprocessed Dan’s death.
• With Tsunade’s assistance, Minato Namikaze becomes the first successful patient to recover. He returns to Konoha, while Tsunade stays behind to continue researching with Ensei.
• Ensei secretly leaves the laboratory every fifteen days to return to his original body, concealing the true nature of his research and his use of the Spirit Transformation Technique.
• Tsunade eventually confronts him after discovering that he has been disappearing for thirteen hours at a time. Their argument shifts from teasing and physical confrontation to a serious discussion about Ensei’s deteriorating humanity and the dangers of his techniques.
• Tsunade warns that the Spirit Transformation Technique is changing Ensei’s soul and chakra. Unlike physical damage, these changes are irreversible, and she believes his original body may already be suffering as well.

Character Developments

• Uchiha Ensei: Remains intensely focused on strength, experimentation, and survival. He rejects emotional attachments and dismisses Konoha’s ideals, but Tsunade’s concern clearly affects him enough to explain his condition. His reliance on clones and spiritual techniques is revealed to be gradually transforming his soul.
• Tsunade: Becomes both Ensei’s teacher and a concerned guardian. Her hemophobia disappears after learning that organ damage might be treatable, showing that she has begun confronting her trauma over Dan’s death. She also reveals lingering resentment toward Konoha and Hiruzen, while trying to prevent Ensei from following Orochimaru’s path.
• Minato Namikaze: Recovers through the new medical methods and returns to Konoha, presumably to restore stability there.
• Dan Katō: Though deceased, his fate remains central to Tsunade’s trauma and motivates her reaction to Ensei’s medical discoveries.
• Kushina Uzumaki: Has asked Tsunade to monitor Ensei, indicating that others are also worried about his mental and spiritual decline.

Significant Themes

• The dangers of scientific advancement: Medical breakthroughs can save lives, but forbidden experimentation and insufficient ethical boundaries may destroy the researcher.
• Irreversible transformation: The chapter emphasizes that changes to the soul cannot be safely reversed or halted once they begin.
• Humanity versus power: Ensei values strength above belonging, compassion, or ideology, while Tsunade fears that this pursuit will strip away his remaining humanity.
• Trauma and healing: Tsunade’s hemophobia and grief over Dan are challenged by the possibility that his death could have been prevented.
• Disillusionment with ideology: Ensei rejects the Will of Fire as propaganda used to justify sending children into war, contrasting sharply with Tsunade’s complicated connection to Konoha.
• Parallels with Orochimaru: Tsunade fears Ensei may become like Orochimaru—an exceptional but morally and spiritually ruined researcher.

Character Interactions

• Ensei and Tsunade maintain a sharp, sarcastic dynamic, trading insults even while relying heavily on each other’s knowledge.
• Tsunade attempts to physically discipline Ensei after catching him returning from his secret activities, but he easily blocks her attack, reminding her of the power imbalance between them.
• Their confrontation becomes emotionally serious when Tsunade questions whether Ensei still possesses genuine human emotions.
• Ensei responds by rejecting pity and Konoha’s ideals, while Tsunade counters that his current path is damaging his mind and soul.
• Despite his resistance, Ensei listens to Tsunade’s warning, revealing that her concern has some influence over him.

Chapter Summary: “Abandon It? Abandon This Power?”

Key Plot Points and Events

• Tsunade uses her exceptional medical knowledge to determine that Uchiha Ensei’s original body is being altered by the Little Ten-Tails. The chakra within it is strengthening his soul but may also be influencing or overwriting his will.
• Ensei compares this phenomenon to the Ōtsutsuki Clan’s Karma, a form of preserved soul or chakra that allows resurrection, though he admits his understanding is incomplete.
• Despite the danger, Ensei resolves to continue pursuing greater power, believing that future threats—including Kaguya, Madara, Black Zetsu, and other Ōtsutsuki—make supreme strength necessary.
• After securing the laboratory with barriers and bringing Zero-Two from the Dragon Vein, Ensei reveals to Tsunade his knowledge of Kaguya Ōtsutsuki and the origin of chakra. He explains that Kaguya came from another world, cultivated the Divine Tree, and was eventually sealed on the moon by her sons, Hagoromo and Hamura.
• To prove his claims, Ensei transports Tsunade to a hidden space and shows her a massive fragment of the Divine Tree’s shell, along with his original body and its overwhelming chakra.
• Tsunade recognizes that Ensei’s chakra has surpassed even the Nine-Tails and urges him to abandon the Little Ten-Tails before its power corrupts him.
• Ensei refuses to give up the power. He believes the body is currently obedient and that its effects may simply result from his soul struggling to contain its immense chakra.
• Returning to the laboratory, Ensei presents the Little Ten-Tails’ flesh and blood as a research subject and encourages Tsunade to study it, suggesting that her work might eventually allow her to master the Rinnegan—or possibly achieve resurrection.

Character Developments

• Uchiha Ensei: Becomes more determined and accepts the possibility that his power may carry existential risks. Although he recognizes the danger of losing control or having his will altered, he prioritizes survival and future strength over caution. He also demonstrates increasing secrecy and manipulation by withholding information about the Byakugan and using the prospect of resurrection to motivate Tsunade.
• Tsunade: Shows strong concern for Ensei’s physical and mental safety. Her medical perspective makes her especially sensitive to the dangers of uncontrolled power and psychological corruption. She remains skeptical of his choices but is fascinated by the Divine Tree’s potential and the possibility of regaining the Rinnegan or reviving the dead.
• Zero-Two: Appears briefly as a controlled asset brought to the laboratory, demonstrating Ensei’s continued ability to manage his resources and secure his research.

Significant Themes

• Power versus identity: Ensei fears that the chakra within his original body may alter his will, raising the question of whether immense power is worth sacrificing one’s autonomy.
• The temptation of forbidden power: Tsunade argues that uncontrollable strength must be abandoned, while Ensei believes dangerous power is still preferable to helplessness.
• Knowledge and secrecy: Ensei reveals carefully selected truths about Kaguya and chakra while concealing information that could compromise him, emphasizing the strategic value of partial disclosure.
• Mortality and resurrection: Tsunade’s possible desire to revive the dead makes the Little Ten-Tails especially tempting, while Ensei uses that desire as leverage.
• Human ambition against cosmic threats: The looming danger of Kaguya and the Ōtsutsuki reinforces Ensei’s belief that ordinary strength is insufficient for survival.

Character Interactions

• Tsunade examines Ensei’s condition and warns him that his attachment to the Little Ten-Tails indicates he may already be influenced by it.
• Ensei counters her concerns by explaining that the creature obeys him completely and may simply be overwhelming his soul with chakra.
• He educates Tsunade about Kaguya, Hagoromo, the Divine Tree, and the origins of chakra, gradually replacing her skepticism with awe after showing her the Divine Tree fragment and his original body.
• Their disagreement reflects their opposing philosophies: Tsunade values control and safety, while Ensei accepts extreme risks in pursuit of the power needed to face future enemies.
• Ensei finally tempts Tsunade into cooperation by suggesting that researching the Little Ten-Tails could help her obtain the Rinnegan and perhaps resurrect the dead.

Chapter Summary: “What Caused His Emotional Numbness”

Key Plot Points and Events

• Tsunade continues researching the Ten-Tails’ flesh and blood with Uchiha Ensei, but her medical knowledge proves insufficient once the investigation reaches more mysterious aspects of the creature.
• As Ensei begins considering dismissing her, Tsunade offers him Hashirama Senju’s Sage Art research and access to the Slug Sage’s teachings. Her condition is that Ensei temporarily stop using, or permanently abandon, his dangerous power.
• Ensei recognizes that Tsunade’s concern affects him emotionally, forcing him to admit that his emotions have been altered. He agrees to stop using the power temporarily but refuses to give up what he has already gained.
• Ensei seals the Little Ten-Tails inside a second Tenseigan body using the Four Symbols Seal. He keeps his original body in an incubation tank and continues operating through the Tenseigan body.
• He explains that the Little Ten-Tails may be connected to Black Zetsu or Ōtsutsuki Isshiki and that it is not yet safe or appropriate to release it. The Dragon Vein space was also nearing its capacity.
• Tsunade gives Ensei two scrolls: Hashirama’s Sage Mode research and a contract with the Slug of Shikkotsu Forest.
• Ensei studies the materials throughout the night and concludes that he may be able to recreate Hashirama’s “Sage Body.”
• When Tsunade later complains that he ignored her after receiving the scrolls, Ensei reveals that he has identified the source of his emotional numbness: abnormal hormone secretion in his current clone body.

Character Developments

• Uchiha Ensei: Becomes increasingly detached and analytical, but his reaction to Tsunade’s concern proves that his emotions have not disappeared entirely. He identifies that his current body, rather than the Little Ten-Tails or his original body, is suppressing his emotional responses. Despite recognizing the problem, he chooses not to correct it because emotional numbness benefits his research.
• Tsunade: Demonstrates genuine concern for Ensei and takes a major risk by sharing Hashirama’s research and offering access to Slug Sage training. Her behavior suggests she wants to guide him away from dangerous experimentation, though she remains frustrated by his coldness and lack of gratitude.
• The Little Ten-Tails: Is treated as a possible source of influence or manipulation. Ensei does not trust it and chooses to seal it away rather than risk allowing it to affect his will.

Significant Themes

• Emotional detachment and self-imposed isolation: Ensei discovers that his own artificial body has trapped him in an “emotional cage,” illustrating the danger of separating physical power from human feeling.
• Power versus control: Ensei refuses to surrender his abilities but agrees to restrain their use. His sealing of the Little Ten-Tails reflects his preference for controlled containment over reckless power.
• Scientific ambition: Both Ensei and Tsunade use research to understand supernatural biology, though Ensei’s methods are more extreme and morally detached.
• Concern disguised as conflict: Tsunade’s attempts to restrain Ensei are motivated by concern, even though he interprets their relationship as practical rather than emotional.
• The body’s influence on identity: The chapter emphasizes that physical changes—particularly hormones and cloned bodies—can alter personality, emotions, and judgment.

Character Interactions

• Tsunade tries to persuade Ensei to abandon his dangerous power, while Ensei remains suspicious of her motives and considers removing her from the project.
• Her willingness to share Hashirama’s legacy surprises Ensei and reveals that he is still capable of being affected by another person’s concern.
• Tsunade later teases and scolds him for being ungrateful, while Ensei responds with blunt indifference.
• Their relationship remains distant and transactional, but Tsunade acts increasingly like a mentor attempting to redirect Ensei, while Ensei grudgingly accepts her help for the sake of his research.

Chapter Summary

Key Plot Points and Events

• Uchiha Ensei signs the summoning contract with Shikkotsu Forest and meets Katsuyu, discovering that she is highly talkative and possesses knowledge of the ancient world.
• Katsuyu explains that Shikkotsu Forest does not have a conventional Sage Art tradition. Its Natural Energy is corrosive and dangerous, making it difficult for humans to absorb.
• Ensei questions Katsuyu about Kaguya, Jigen, the God-Demon Era, powerful monsters, the three sacred lands, and Natural Energy cultivation. Katsuyu knows little about Jigen or Kaguya’s sealing but reveals that Natural Energy once became much more violent after major changes in the world.
• Katsuyu describes Sage cultivation as sensing Natural Energy, intentionally absorbing it, and surviving the process. Ensei abandons the idea of directly mastering it because his mixed chakra cannot safely merge with Natural Energy.
• Ensei instead focuses on creating a body or clone capable of containing Sage Chakra. His first attempt fails catastrophically, turning to stone before he can release the Spirit Transformation Technique.
• He summons Chachamaru, a growing Ninja Cat, and uses Katsuyu’s guidance to improve the cat’s Natural Energy absorption and Sage Chakra balance.
• Over the following months, Ensei and Tsunade’s experiments progress:
  • After three months, Tsunade leaves and returns to Tanzaku Town.
  • After six months, Ensei masters the initial stage of Sage Mode through a specially created clone, though he cannot yet use it in combat.
  • After nine months, his original body stabilizes enough for him to safely return to it.
  • After eleven months, his experiments with the Little Ten-Tails’ flesh, blood, and Tailed Beast chakra trigger an ancient mark, suggesting a major new development.

Character Developments

• Uchiha Ensei becomes more knowledgeable about Natural Energy and adapts his strategy after realizing direct Sage Mode cultivation is too dangerous for his current chakra composition. Rather than giving up, he develops a safer artificial method through clones and experimentation.
• Katsuyu is revealed as ancient, unusually knowledgeable, and far more personable than expected. Her casual remarks hint at forgotten history and the long lifespan of her species.
• Tsunade acts as Ensei’s research partner and provides access to the First Hokage’s cells, though she remains protective of Hashirama’s reputation.
• Chachamaru has grown physically but has not significantly increased his Sage Chakra. Under Katsuyu’s instruction, he begins learning how to absorb Natural Energy more effectively.

Significant Themes

• Knowledge versus danger: Ensei seeks ancient power but learns that understanding a technique does not make it safe to use.
• Adaptation and experimentation: Unable to follow the traditional path, Ensei relies on scientific research, artificial bodies, clones, and biological experimentation.
• The instability of the natural world: Natural Energy has changed from a gentle force into something violent and corrosive, implying that ancient cosmic events permanently altered the world.
• Forgotten history: Katsuyu’s memories provide fragmented clues about Kaguya, the God-Demon Era, and the origins of powerful beings, while emphasizing how much of the past has been lost.
• Creation and transformation: Ensei’s work with clones, Sage Chakra, and the Little Ten-Tails reflects his ongoing attempt to reshape bodies and unlock new forms of power.

Character Interactions

• Ensei repeatedly questions Katsuyu, taking advantage of her openness and curiosity to gather information about history and cultivation.
• Katsuyu teases Ensei about his inability to become a shrine maiden and casually discusses ancient legends, creating a contrast between her immense age and innocent personality.
• Tsunade and Ensei clash humorously over his disrespectful attitude toward Hashirama, with Ensei escaping before she can lecture him.
• Katsuyu instructs Chachamaru directly, while the cat remains terrified of her overwhelming power despite its irritation at being treated like a “little cat.”
• Ensei observes and learns from Katsuyu’s guidance, using Chachamaru’s cultivation as a practical model for his own Sage Chakra research.
