• The clone, locked at Peak Kage Level, combines the combat systems of Madara and Izuna Uchiha:
  • Madara’s overwhelming, destructive strength.
  • Izuna’s deceptive, stealthy, assassination-focused techniques.
• This constantly shifting style prevents Sasuke from adapting. The clone alternates between crushing frontal attacks and unpredictable ambushes, exhausting Sasuke physically and mentally.

• When the clone briefly transitions between attacks and exposes a tiny opening, Sasuke immediately launches a fierce counterattack.

• The medical team stabilizes Sasuke’s condition by repairing damaged meridians, neutralizing the lightning poison, regulating his vitality and blood, and beginning long-term recovery.
• Natsu watches the treatment, then leaves after ordering that Sasuke visit him once he has recovered.
• Fugaku arrives in a panic and asks about Sasuke’s condition. Natsu reassures him that Sasuke’s life is no longer in danger, allowing Fugaku to finally release his fear and tension.

Character development

• Sasuke: Demonstrates extraordinary stubbornness, courage, and willingness to risk death. Though his injuries are almost fatal, he refuses to surrender during the trial, proving that he possesses the mentality required to pursue the path of the strong. His recovery marks the beginning of a new stage in his transformation and the Uchiha clan’s development.
• Natsu: Gains deep satisfaction and approval from Sasuke’s defiance and resolve, though he also feels regret over allowing the trial to approach genuine death. He believes physical injuries and damage to one’s foundation can be repaired, while the will to challenge fate is rare and invaluable. His calm exterior contrasts with the seriousness of what Sasuke endured.
• Fugaku: Reveals intense paternal fear and emotional vulnerability. His anger stems from nearly losing his son, and his relief after hearing Sasuke is safe highlights the depth of his concern.
• Vallen and Caesar: Show professionalism and growing expertise as they respond quickly and efficiently to a medical crisis far more severe than Sasuke’s previous training injuries.

Major themes

• The price of strength: True cultivation requires more than talent and resources; it demands life-and-death trials, perseverance, and the willingness to confront despair.
• Courage versus recklessness: Sasuke’s bravery earns Natsu’s admiration, but the severity of his injuries exposes the dangerous boundary between heroic resolve and needless self-destruction.
• Parental love versus the philosophy of strength: Fugaku sees Sasuke’s ordeal as terrifying and unacceptable, while Natsu views it as a necessary test of character. Their opposing perspectives create the chapter’s central emotional contrast.
• Rebirth and transformation: Sasuke’s recovery symbolizes the beginning of a new phase for both him and the Uchiha clan, suggesting that suffering will lead to renewed power and growth.
• Emotional restraint: Natsu remains outwardly calm despite the near-fatal outcome, while Fugaku openly expresses rage, fear, and relief, emphasizing their sharply different personalities.

Character interactions

• Fugaku confronts Natsu over the terrifying trial, expressing anger born from fear for Sasuke’s life.
• Natsu entrusts Sasuke’s treatment to Vallen, Caesar, and the medical staff rather than intervening further himself.
• Vallen and Caesar respond urgently and collaboratively, supported by the Laboratory’s researchers and medical ninja.

Chapter Summary: “Setsuna Was Speechless: I Really Want to Retire”

Key Plot Points and Events

• After the brutal battle in which Sasuke was gravely injured, Fugaku finally relaxes once Natsu confirms that Sasuke’s condition has stabilized.
• Fugaku complains about the extreme danger and emotional strain he has endured, comparing himself to an aging father overwhelmed by his son’s reckless adventures.
• Natsu dismisses Fugaku’s “middle-aged” complaints by reminding him that the Uchiha Clan now possesses lifespans beginning at ten thousand years, making Fugaku’s fifty years effectively youthful.
• Setsuna arrives and confirms that he witnessed the earlier events, including Sasuke’s near-fatal injury. He asks directly whether Sasuke will survive.
• Natsu explains that Sasuke is recovering in a Nutrient Pod, aided by Vallen and Caesar Clown’s medical technology. Although Sasuke needs prolonged rest, he will suffer no permanent damage.
• Once Sasuke’s safety is confirmed, Setsuna reports on the Uchiha Clan’s administrative situation:
  • Resources and populations from three islands linked to Origin Island have been reorganized.
  • Security, defenses, and cultivation zones have been established.
  • Confusion remains between the old and new administrative systems, with authority and responsibilities still needing clarification.
• Natsu, Fugaku, and Setsuna shift their attention from Sasuke’s recovery to the continued expansion and organization of the Uchiha Clan.

Character Developments

• Natsu: Remains calm, blunt, and authoritative. He reassures Fugaku about Sasuke while immediately focusing on the larger needs of the clan. His transformation of the Uchiha Clan has made him its central leader and source of authority.
• Setsuna: Shows deep concern for Sasuke but also frustration over being forced back into administrative work after expecting to retire. His restored youth and longevity have extended his life but denied him the peaceful retirement he wanted.
• Sasuke: Though mostly absent from the scene, his survival and recovery serve as the emotional center of the chapter. His injuries demonstrate the dangers of the preceding battle.

Significant Themes

• The burden of immortality: The Uchiha’s extraordinary longevity removes aging and death but creates new obligations, including centuries or millennia of work.
• Family and parental fear: Fugaku’s emotional distress shows that extraordinary power and long life cannot suppress a parent’s instinctive fear for a child.
• Duty versus retirement: Setsuna and the older generation expected to withdraw from public affairs, but the clan’s growth forces them back into service.
• Order amid expansion: The Uchiha Clan’s rise brings prosperity and power, but also administrative complexity that must be carefully managed.
• The cost of progress: Natsu’s reforms have elevated the clan, yet they require sacrifices from its members, especially the elders.

Character Interactions

• Fugaku vents his frustration to Natsu, but Natsu humorously and bluntly refutes his complaints about being old.
• Setsuna shares Fugaku’s concern for Sasuke and finds solidarity in Fugaku’s frustration, though his own grievance concerns being forced back into work after rejuvenation.
• Natsu reassures both men about Sasuke’s recovery, then listens to Setsuna’s detailed administrative report.
• Fugaku and Setsuna transition from worried family members to responsible clan officials, emphasizing how personal concerns must be balanced with collective duty.

Chapter Summary

Madara Uchiha observes a peaceful-looking village from a cliff on an island in the East Blue. The village’s simple, harmonious life briefly moves him, reminding him of the peace and safety ordinary people deserve. However, his admiration quickly turns to regret and anger because he knows the village’s tranquility is unusual rather than representative of the East Blue as a whole.
After traveling through the region for more than twenty days, Madara has seen widespread poverty, ruined villages, piracy, village raids, and the suffering of fishermen and farmers. He recognizes that the East Blue’s reputation as the safest of the Four Blues is largely a façade. The World Government and hereditary nobles maintain their wealth by exploiting commoners, while the Marines protect the nobles’ privileges and suppress popular resistance. People who oppose oppression are branded as pirates, rebels, or traitors and are violently eliminated.
Madara is especially disgusted by the corruption among low-ranking Marines, many of whom secretly cooperate with pirates. Pirates hand over much of their stolen wealth as bribes, while Marines pretend to fight them but actually provide protection and share the profits. Realizing that the region’s “peace” rests on exploitation and collusion, Madara’s brief warmth disappears and his killing intent emerges.
The chapter then contrasts the East Blue with the West Blue, which is now controlled by the Uchiha Clan under Natsu’s leadership. Once known for violence and disorder, the West Blue has supposedly been transformed within two or three years through strict Uchiha rule. The clan abolished the noble system, hereditary privilege, and class barriers, declaring all inhabitants equal regardless of race or origin. Citizens are required to follow the Uchiha Clan’s laws and authority.
Natsu has also created a layered security and administrative system. The Heavenly Star Guard, made up of developing Uchiha members, supervises local conduct and prevents corruption. The Earthly Chief Guard consists of trustworthy local commoners who handle patrols, disputes, and everyday protection. The Nightingale Guard, composed of stronger and more talented Uchiha members, oversees administration, resource distribution, officials, and local welfare. The chapter ends while describing this system.

Character Development and Interactions

• Madara Uchiha: His reaction reveals both his longing for genuine peace and his growing hatred of corrupt systems that create suffering. His observations show that he judges societies by their treatment of ordinary people rather than by their public reputation.
• Natsu: Although he does not appear directly, his earlier analysis of the World Government and his transformation of the West Blue strongly shape Madara’s thoughts. He is portrayed as a powerful, authoritarian reformer who has created order by dismantling the old ruling class.
• Madara and Natsu: Their earlier conversation provides the framework for Madara’s interpretation of the East Blue. Madara’s comparison of the two seas suggests that he is increasingly evaluating Natsu’s rule as an alternative to World Government oppression.

Significant Themes

• False peace versus genuine peace: The East Blue’s calm appearance hides exploitation, violence, and corruption.
• Class oppression and institutional injustice: Nobles, the World Government, and corrupt Marines form a system that extracts wealth from commoners and suppresses resistance.
• Order through authoritarian control: The West Blue’s stability is presented as the result of strict Uchiha rule rather than democratic or traditional government.
• The burden of witnessing suffering: Madara’s personal experience with war and poverty deepens his desire for peace while also intensifying his anger toward those who perpetuate injustice.
• Law, equality, and control: The Uchiha system removes hereditary privilege and promotes equality, but it also demands complete obedience to Uchiha authority.

Chapter Summary: Madara Uchiha’s Reflections

Key Plot Points and Events

• The West Blue has been transformed under the Uchiha Clan’s strict administration. Corruption, piracy, oppression, and official collusion with criminals have been nearly eliminated through harsh laws, rapid arrests, and severe executions.
• As a result, the region has entered a prosperous “golden age.” Transportation networks, including sea trains and passenger ships, connect the islands, allowing ordinary people to travel freely, build wealth, and enjoy unprecedented security.
• Madara reflects on the contrast between the West Blue’s genuine peace and the East Blue’s false, superficial stability. He concludes that the World Government-controlled seas have rotted beneath their appearance of order.
• A Night Owl Guard member arrives through spatial distortion to deliver a message from Natsu: Madara must immediately travel to the New Marine Headquarters in the New World after completing his recovery.
• The messenger explains that a major confrontation recently occurred on a deserted New World island. Members of the Uchiha Clan encountered the Straw Hat Pirates, followed by the arrival of the Flying Pirates and Blackbeard Pirates. Marine forces, led by an admiral, intervened but eventually withdrew because of the dangerous balance of powers.
• Madara recognizes that the New World is entering a period of upheaval, with pirates, Marines, and other major factions locked in unstable opposition as the old order begins to collapse.
• Before discussing his mission, Madara asks about the condition of the Uchiha Clan and Origin Island. He learns that:
  • Clan administration remains stable.
  • Sasuke is recovering from severe injuries sustained during extreme training and is not in danger.
  • Transportation and infrastructure in the West Blue continue to expand.
  • The Heavenly Star Guard and Earthly Chief Guard are eliminating remaining hidden threats.
  • Ancient records and secret maritime scrolls have been catalogued and secured in the Origin Island library.
• Reassured by the report, Madara decides he is ready to leave for the New World and confront the coming crisis.
• The chapter ends with Natsu returning briefly to his residence, greeting Izumi, and proceeding toward the clan’s heavily guarded experimental chamber.

Character Developments

• Madara Uchiha: His reflections deepen his belief that strong, uncompromising authority can create genuine peace. His concern for the clan and its people is evident, but after confirming their stability, he shifts from contemplation to readiness for action. He accepts that his period of recovery is over and prepares to reenter the broader conflict.
• Natsu: Though absent for most of the chapter, he is portrayed as a careful and reliable leader whose decision to summon Madara indicates that the New World situation is strategically significant.
• Sasuke: His injuries reveal the severity of his training, but his recovery confirms that his long-term potential remains intact.
• Night Owl Guard messenger: He demonstrates discipline, loyalty, and professionalism while delivering a comprehensive report to Madara.
• Natsu and Izumi: Their brief interaction suggests an established personal connection, though the chapter does not explore it in depth.

Significant Themes

• Order through authoritarian justice: The West Blue’s prosperity is built on strict laws, immediate punishment, and the suppression of disorder. The chapter presents this system as effective, while also highlighting its severity.
• Appearance versus reality: The East Blue’s celebrated peace is contrasted with the West Blue’s less publicized but genuine stability, criticizing systems that value reputation over actual welfare.
• Governance and prosperity: Reliable administration, public infrastructure, security, and social stability allow ordinary citizens to improve their lives.
• The collapse of the old order: The New World conflict signals a coming reshuffling of power among pirates, Marines, and independent factions.
• Duty versus contemplation: Madara’s quiet reflections are interrupted by political developments, forcing him to leave a peaceful environment and return to conflict.

Character Interactions

• The Night Owl Guard respectfully informs Madara of Natsu’s summons and provides a detailed account of the New World battle.
• Madara questions the messenger about both the political crisis and the condition of the Uchiha Clan, showing that he values strategic awareness and remains deeply invested in his people.
• The report reassures Madara that the clan’s leadership, military forces, infrastructure, research, and public welfare systems are functioning effectively.
• Natsu briefly greets Izumi before heading toward the experimental chamber, closing the chapter with a transition from peaceful domestic life to the clan’s secretive and militarized operations.

Chapter Summary: Izuna Uchiha’s Research Progress

Key Plot Points and Events

• The laboratory is heavily sealed with barriers to contain chakra fluctuations, experiments, and any accidental jutsu effects.
• Izuna Uchiha continues researching in the lab, surrounded by Hashirama Cell samples, Natsu’s cells, experimental fluids, and complex sealing formulas.
• His Impure World Reincarnation body has been extensively modified using genetic serums derived from Hashirama and Natsu’s cells. It now surpasses his former living body in strength and chakra capacity, though it remains an undead puppet.
• Izuna’s main projects include:
  • Perfecting and refining Impure World Reincarnation.
  • Developing new ninjutsu based on Natsu’s ideas.
  • Simplifying and improving the Flying Thunder God technique.
• Natsu visits the laboratory to ask about the simplified Flying Thunder God.
• Izuna explains that the technique’s basic framework is complete. It lowers the talent and technical requirements enough that more capable clan members may be able to learn it.
• However, the simplified version has major limitations:
  • Its teleportation range is reduced to a few thousand meters.
  • Its markers are less durable and can be destroyed by powerful Haki or ninjutsu.
  • Its reaction speed is inferior, making it unsafe for split-second evasions in life-or-death combat.
• Natsu examines the calculations and runes to judge whether the technique is practically useful.

Character Developments

• Izuna Uchiha: Izuna is portrayed as an extraordinarily dedicated researcher who has sacrificed rest for scientific and jutsu advancement. Although his reanimated body is stronger than ever, he remains deeply dissatisfied because it is not a true living body. His desire for genuine resurrection and freedom from Impure World Reincarnation becomes increasingly clear.
• Natsu: Natsu acts as Izuna’s collaborator and evaluator. He is directly involved in the development of new techniques and approaches Izuna with practical concerns about making the Flying Thunder God usable by more people.
• Madara Uchiha: Though absent from the laboratory, Madara is crucial to Izuna’s future. Izuna’s resurrection depends on Madara successfully fusing with the genetic serum, awakening the Rinnegan, and eventually using the Rinne Rebirth Technique.

Significant Themes

• Scientific and jutsu innovation: The chapter emphasizes painstaking experimentation, calculation, and iterative improvement rather than raw combat power.
• The cost of power: Izuna’s enhanced body grants him greater strength but cannot provide the humanity, independence, and security of a true body.
• Hope dependent on others: Izuna’s freedom and resurrection rest entirely on Madara’s success, leaving him vulnerable to events beyond his control.
• Accessibility versus perfection: The simplified Flying Thunder God sacrifices range, stability, and speed in exchange for allowing more people to learn it.
• Immortality and identity: Despite being powerful, Izuna fears remaining permanently trapped as an undead construct, highlighting the difference between survival and truly living.

Character Interactions

• Natsu enters the laboratory and asks Izuna directly about the progress of the simplified Flying Thunder God.
• Izuna presents the completed framework and honestly explains both its advantages and weaknesses rather than overstating its success.
• Their interaction reflects a cooperative relationship: Izuna provides technical expertise, while Natsu evaluates the technique’s battlefield value.
• As Natsu studies the scroll, Izuna’s unspoken anxiety about resurrection contrasts with his calm, professional explanation of the research.
