Chapter Summaries

Chapter Summary

Key Plot Points and Events

• Uchiha Sagiri asks her older brother, Setsuna, to train her after gaining permission from their mother, Riko. Setsuna begins teaching her basic ninja exercises in the woods.
• Watching Sagiri work hard, Setsuna reflects on her innocence, kindness, and perseverance. He compares her favorably with his classmates and questions why Itachi would ever consider someone like her deserving death during the Uchiha massacre.
• Setsuna begins another life simulation and obtains the Mind Disturbance Technique. In this timeline, he uses the Mind Body Switch Technique to manipulate Second Pillar into attacking Itachi, causing Itachi to accidentally kill him and lose control emotionally.
• Setsuna warns Uchiha Yashiro about the coming Uchiha Clan Downfall, escapes Konoha, and eventually reaches Kirigakure.
• While investigating Kirigakure, Setsuna attempts to flee the village but is overwhelmed and killed by pursuing ninja. He chooses the Mind Disturbance Technique as his reward, adding it to his abilities.
• Reviewing the simulation, Setsuna concludes that brute force cannot get him out of Kirigakure. He considers two possible solutions:
  1. Learn more Kirigakure-compatible techniques, especially Water Style and other skills suited to the misty environment.
  2. Create chaos within Kirigakure by exposing that Mizukage Yagura is being controlled by genjutsu.
• Setsuna develops a plan involving Ao. By controlling Ao with the Mind Body Switch Technique, he hopes to make Ao use his Byakugan to confirm that Yagura is under genjutsu. Because Ao is a trusted and credible figure, Setsuna believes his testimony would be more convincing than his own.
• In the next simulation, Setsuna successfully reaches Kirigakure and investigates Ao. At six years and seven months, he takes control of Ao and brings him toward the Mizukage’s office so Ao can inspect Yagura.
• Ao dies during the attempt, drawing suspicion to Setsuna. Yagura confronts him, and Tobi Uchiha appears. Setsuna attacks Tobi with the Great Fire Destruction Technique and tries to take his Mangekyō Sharingan, but fails and is killed.

Character Developments

• Uchiha Setsuna: Becomes increasingly strategic and pragmatic. Rather than relying solely on combat strength, he experiments with manipulation, espionage, psychological tactics, and political destabilization. His repeated simulations make him more cautious and efficient, though he remains driven by the need to prevent the Uchiha massacre.
• Uchiha Sagiri: Takes an important step toward becoming a shinobi by beginning formal training. Her diligence and good nature deepen Setsuna’s protective feelings toward her.
• Uchiha Itachi: Is portrayed as emotionally vulnerable and capable of losing control after accidentally killing Second Pillar. Setsuna’s resentment toward Itachi intensifies because he views Sagiri and other innocent clan members as undeserving of death.
• Ao: Becomes central to Setsuna’s plan to expose Yagura’s manipulation, though the attempt results in his death.
• Tobi Uchiha: Appears as a powerful and dangerous obstacle. Setsuna’s inability to defeat him or seize his Mangekyō Sharingan emphasizes the gap between Setsuna’s current abilities and the strength needed to change the future.

Significant Themes

• Preventing inevitable tragedy: Setsuna is racing against the approaching Uchiha massacre and knows that merely gaining moderate strength will not be enough to stop it.
• The value and cost of repeated simulations: Each death provides information and techniques, but Setsuna has limited time and must use each simulation efficiently.
• Strategy over strength: Since Setsuna cannot currently increase his Chakra level or overpower major villages, he seeks indirect solutions through infiltration, possession, and political disruption.
• Innocence amid political violence: Sagiri’s kindness and hard work contrast sharply with the brutal fate awaiting the Uchiha clan.
• Trust and credibility: Setsuna realizes that the truth about Yagura’s genjutsu will only be accepted if it comes from someone respected, leading him to manipulate Ao rather than speak directly himself.

Character Interactions

• Setsuna and Sagiri: Their affectionate sibling relationship grows as Setsuna begins training her and becomes more protective of her.
• Setsuna and Itachi: Setsuna manipulates Itachi indirectly by controlling Second Pillar, causing an accidental death and worsening Setsuna’s antagonism toward him.
• Setsuna and Ao: Setsuna uses Ao as a tool to investigate Yagura, demonstrating his willingness to control others for a larger goal.
• Setsuna and Tobi: Their brief confrontation ends with Setsuna attempting—and failing—to take Tobi’s Mangekyō Sharingan, leading to Setsuna’s death and highlighting Tobi’s superiority.

Chapter Summary

Key Plot Points and Events

• Uchiha Setsuna reflects on his failed attempt to control Ao and use the Byakugan to investigate the Mizukage’s office. Tobi Uchiha detected the plan and killed Ao, causing it to fail.
• Setsuna concludes that his strategy was sound and identifies the night of the Uchiha Clan Massacre as the ideal opportunity to act, since Tobi will be occupied attacking the Uchiha Police Force alongside Itachi.
• He plans to exploit the resulting chaos to escape Kirigakure and travel to Kumogakure.
• Setsuna claims his simulation reward and chooses the Mind Body Switch Technique, instantly mastering it.

  • Second: Hyuga Hinata
  • Third: Nara Shikamaru
  • Setsuna ranks thirty-first.
• The top ten students receive prizes, but Setsuna is uninterested in his ranking and leaves immediately after class, eager to conduct another life simulation and improve his escape plan.
• Sasuke returns home and proudly tells Mikoto that he placed first.

Character Developments

• Uchiha Setsuna: Becomes more determined and strategic after his failed plan. He gains the Mind Body Switch Technique and focuses entirely on escaping Kirigakure rather than school performance. His apparent indifference to ranking contrasts with his hidden strength and long-term goals.
• Uchiha Sasuke: Demonstrates his academic and physical superiority by ranking first, reinforcing his reputation as a young Uchiha prodigy. He remains proud of his achievement and seeks Mikoto’s recognition.
• Hyuga Hinata: Places second and shows concern for Setsuna, considering whether to share her prize with him. She misunderstands his lack of concern as discouragement and assumes he intends to train harder.
• Nara Shikamaru: Places third despite his usual laziness. Ino and Choji recognize that he could have ranked even higher if he had made a serious effort.
• Sakura and Ino: Sakura compares Setsuna unfavorably with Sasuke, revealing her admiration for Sasuke and her dismissive attitude toward Setsuna.
• Naruto and Kiba: Both anxiously await the results and hope to perform well, though neither appears among the top students.

Significant Themes

• Strategic planning and adaptation: Setsuna learns from failure and identifies a future moment when Tobi will be absent or distracted.
• Escaping fate and survival: The planned Uchiha massacre becomes a potential turning point in Setsuna’s effort to escape Kirigakure.
• Appearance versus reality: Others interpret Setsuna as a mediocre, disappointed student, while he is secretly an exceptionally capable ninja pursuing far more significant objectives.
• Youthful school life versus deadly shinobi politics: Ordinary exam rankings and student rivalries occur alongside Setsuna’s calculations about massacres, espionage, and escape.
• Talent and privilege: The strong performances of Sasuke and Hinata reflect their clan backgrounds and early training, while Shikamaru’s intelligence allows him to excel without apparent effort.

Character Interactions

• Students gossip about Sasuke’s success and criticize less impressive members of the Uchiha Clan, indirectly insulting Setsuna.
• Iruka encourages the class not to lose heart over their results and later distributes prizes to the top ten students.
• Ino informs Setsuna that he ranked thirty-first.
• Hinata watches Setsuna with concern and contemplates sharing her reward, but she never approaches him.
• Sasuke celebrates his first-place result with his mother, Mikoto, at home.

Chapter Summary

Key Plot Points and Events

• Mikoto Uchiha warmly praises Second Pillar and offers to cook whatever he wants, contrasting sharply with Uchiha Setsuna’s more subdued interaction with his grandfather, Kayan, after receiving mediocre results. Kayan encourages Setsuna to continue working hard.
• In the next life simulation, Setsuna follows a long-term escape and survival plan:
  • At six, he learns the Mind Body Switch Technique.
  • At six years and ten months, he escapes to Kirigakure.
  • During the Uchiha clan’s downfall, he controls Ao and uses the Byakugan to inspect the Mizukage’s office.
  • He reveals that Yagura is under a genjutsu, prompting Ao and the Kirigakure elder Genji to investigate.
  • The revelation causes conflict and chaos within Kirigakure.
  • After waiting several months, Setsuna escapes during the resulting factional battle, killing more than a dozen pursuing ninja.
  • He travels to the Land of Lightning and contacts Kumogakure, but is immediately imprisoned.
• Setsuna spends three years cultivating in captivity. At age nine, his chakra finally reaches the Elite Jonin level.
• Tobi Uchiha arrives through an apparent connection with Orochimaru and confronts Setsuna, demanding to know why he exposed Yagura’s condition and interfered with his plans.
• Setsuna attacks Tobi with the Great Fire Destruction Technique and attempts to remove his mask and steal his Mangekyō Sharingan, but fails and is killed.
• As his reward, Setsuna chooses Elite Jonin-level chakra rather than the item he held at death.

Character Developments

• Setsuna gains a major power boost: both his chakra reserves and chakra control now match those of an Elite Jonin, making all of his existing techniques substantially stronger.
• His decades of simulated experience have made him increasingly calculating, patient, and knowledgeable about the political dynamics of the ninja world.
• He recognizes that his strategy in Kirigakure was successful because it created internal chaos without requiring him to fight the entire village directly.
• Setsuna becomes more cautious regarding Tobi, realizing that revealing Yagura’s secret made him a personal target.
• He also understands that Kumogakure never trusted him and likely intended to exploit his Uchiha bloodline rather than treat him as an ally.

Significant Themes

• Accumulated experience and sacrifice: Setsuna’s power is the result of more than thirty simulated years of repeated cultivation and deaths.
• Manipulation and political chaos: Rather than relying solely on strength, Setsuna destabilizes Kirigakure by exposing Yagura’s genjutsu.
• Mistrust and exploitation: Kumogakure accepts Setsuna only for practical reasons and treats him as a resource or potential breeding tool.
• The value of strength in the shinobi world: Setsuna reflects that ordinary Jonin will eventually become insignificant as increasingly powerful Kage-level and tailed-beast threats emerge.
• Cause and consequence: His successful interference in Yagura’s situation indirectly leads Tobi to hunt him down.

Character Interactions

• Mikoto and Second Pillar: Mikoto shows affection and approval, promising to prepare any meal he wants.
• Setsuna and Kayan: Kayan responds to Setsuna’s poor results with encouragement rather than criticism, reinforcing their supportive grandfather-grandson relationship.
• Setsuna and Ao: Setsuna uses the Mind Body Switch Technique to control Ao and exploit his access to the Mizukage’s office.
• Ao and Genji: Ao reports what he witnessed, leading Genji to investigate Yagura and prepare against the Mizukage’s faction.
• Setsuna and Tobi: Tobi confronts Setsuna over his interference with Yagura and attacks him after Setsuna attempts to seize his Mangekyō Sharingan.
• Tobi and Orochimaru: The chapter implies that Tobi reached Kumogakure with Orochimaru’s assistance, likely through a secret agreement.

Chapter Summary

Uchiha Setsuna considers fleeing Konoha directly to Kumogakure, believing his current Elite Jonin-level strength gives him a reasonable chance of escaping Root and Anbu pursuit. He expects Kumogakure to protect him rather than compromise with Konoha, allowing him to remain imprisoned while training toward Kage level. His ultimate goal is to gain enough power and influence to prevent the Uchiha Clan Downfall.
Setsuna recognizes the major obstacles in that plan: Uchiha Itachi’s unwavering loyalty and desperation, Konoha’s ruthless leadership, and Fugaku Uchiha’s incompetence. He views Fugaku as an enemy rather than an ally and refuses to rely on him during the coming crisis.
At school, Hyuga Hinata secretly gives Setsuna a training manual she compiled herself. Although he appreciates her kindness, Setsuna returns it because accepting it might attract the Hyuga Clan’s attention and jeopardize his larger plans. Hinata is hurt by his rejection, while Setsuna feels guilty but believes sacrificing their relationship is necessary.
The next morning, Setsuna begins another simulation. At six, he escapes Konoha after giving Uchiha Yashiro information about the future Night of the Uchiha Clan Downfall. Root and Anbu pursue him across several nations, but he eventually reaches the Land of Lightning. Itachi confronts him, accusing him of worsening the Uchiha-Konoha conflict and calling him a traitor. Setsuna attacks with Fire Style: Dragon Flame Song, but Itachi overwhelms him until Kumogakure forces arrive and defeat the Konoha pursuers.
In Kumogakure, the Raikage questions Setsuna about his motives. Setsuna reveals that Konoha’s leadership intends to destroy the Uchiha Clan and offers information about Konoha, but the Raikage remains suspicious and imprisons him in a secret chamber. After the Uchiha massacre occurs, Setsuna again offers cooperation in exchange for revenge, yet Kumogakure still refuses to trust him.
Setsuna remains imprisoned for years and unsuccessfully attempts escape. At age eight and a half, Kumogakure uses his information to launch a war against Konoha, gaining a major strategic advantage. The conflict lasts until Setsuna is eleven. Kumogakure wins, though only narrowly, while Konoha suffers devastating losses and casualties.
After the war, Itachi infiltrates Kumogakure and confronts Setsuna in prison. He blames Setsuna for both the destruction of the Uchiha Clan and Konoha’s defeat, accusing him of betraying everyone. Itachi attacks, and Setsuna is unable to resist. The simulation ends with Setsuna’s death.

Character Development and Interactions

• Setsuna: Becomes increasingly pragmatic and calculating, prioritizing his long-term goal over personal relationships and accepting morally questionable alliances. However, the simulation reveals that fleeing to Kumogakure may save him temporarily without giving him meaningful freedom or control.
• Hinata: Demonstrates initiative and affection by creating a training manual for Setsuna, but is emotionally hurt when he rejects it.
• Itachi: Remains committed to protecting the Uchiha’s surviving members and Konoha, but views Setsuna as a traitor whose actions caused catastrophic consequences. His hatred ultimately leads him to kill Setsuna.
• Raikage/Kumogakure: Treat Setsuna as a potentially useful but fundamentally untrustworthy asset, exploiting his intelligence while keeping him imprisoned.
• Fugaku: Is presented through Setsuna’s thoughts as unreliable and potentially obstructive.

Significant Themes

• Trust and betrayal: Every faction views Setsuna with suspicion, while Setsuna likewise trusts neither Konoha, Fugaku, nor Kumogakure.
• Sacrifice for a greater goal: Setsuna rejects Hinata’s kindness and personal happiness to preserve his chance of changing the future.
• Powerlessness and unintended consequences: Escape prevents Setsuna from being immediately killed, but his information helps trigger a destructive war and still fails to save the Uchiha.
• Moral ambiguity: Setsuna’s attempt to prevent genocide indirectly contributes to widespread death, leaving him condemned by both Konoha and Itachi.
• The limits of strategic planning: Despite carefully analyzing political realities, Setsuna cannot control how others interpret or exploit his actions.

Chapter Summary

Key Plot Points and Events

• Uchiha Setsuna completes another Life Simulation and is offered a choice between receiving nothing or regaining the item he held before death. He chooses the latter, but nothing appears, proving he had possessed nothing at the time of death.
• Although the simulation was successful in one respect—it extended his life by five years—Setsuna is disappointed that his Chakra level remains at Elite Jonin and his Two-Tomoe Sharingan fails to advance to Three Tomoe.
• He analyzes his Kumogakure strategy. Despite giving Kumogakure substantial intelligence about Konoha, the village still imprisoned him and kept him under close guard rather than trusting him.
• Setsuna concludes that revealing too much intelligence only encourages war while doing nothing to secure his freedom. In future simulations, he plans to provide less information so Kumogakure will remain at peace with Konoha, allowing him to survive longer.
• He considers abandoning Kumogakure temporarily to seek ninjutsu from Konoha or Kirigakure, but ultimately decides to continue pursuing greater longevity through the Kumogakure route because Chakra remains the foundation of his strength.
• Setsuna also considers a more dangerous plan: secretly leaking Konoha intelligence to Kumogakure while remaining in Konoha, potentially provoking a war that might force the village leadership to ease its hostility toward the Uchiha—or use the war as an excuse to destroy the clan.
• The chapter then shifts to the Ninja Academy, where Iruka teaches the Clone Technique, one of the Three Basic Jutsu.
• Sasuke quickly masters the technique, earning Iruka’s praise and the admiration of most classmates. Naruto is notably unimpressed and resentful.
• Setsuna pretends to practice while privately dismissing the Clone Technique as largely useless compared with more advanced clone techniques such as Shadow, Water, or Earth Clones.

Character Developments

• Uchiha Setsuna: Becomes more analytical and pragmatic after recognizing the limits of his natural talent. He accepts that additional time alone may not improve his Chakra or Sharingan and begins considering political manipulation, espionage, and controlled provocation as alternative strategies.
• Sasuke: Demonstrates exceptional talent by learning the Clone Technique immediately, reinforcing his reputation as the class prodigy.
• Naruto: Displays his familiar competitiveness and dissatisfaction when Sasuke receives praise.
• Iruka: Acts as a patient and encouraging instructor, explaining the technique and praising Sasuke’s achievement.

Significant Themes

• Talent versus time: Setsuna’s central frustration is that even five additional years produce no advancement in his innate abilities, suggesting that time cannot fully compensate for limited talent.
• Survival through strategy: Setsuna relies less on direct strength and more on manipulating political circumstances, village rivalries, and wartime conditions.
• The danger of trust and espionage: Kumogakure’s refusal to trust Setsuna demonstrates that information can increase suspicion rather than earn freedom.
• The Uchiha’s precarious position: Setsuna weighs whether war could temporarily protect the clan or instead give Konoha’s leadership an opportunity to eliminate it.
• Generational perspective: Setsuna’s mature, cynical outlook contrasts sharply with the children’s excitement over a basic academy technique.

Character Interactions

• Setsuna internally evaluates Kumogakure’s treatment of him and its unwillingness to trust him despite his intelligence contributions.
• He reflects on Itachi’s likely reluctance to attack Kumogakure because of his obligations to Sasuke, referring to Sasuke as “Second Pillar.”
• Iruka teaches the class and praises Sasuke after his successful demonstration.
• Sasuke’s achievement inspires admiration from most classmates but provokes Naruto’s resentment.
• Setsuna outwardly participates in the lesson while inwardly mocking the childish exercise and wishing his academy life would end.

• The Past's Impact: Uchiha Setsuna's experience in the Life Simulator shows how past events can shape one's present decisions and future goals.
• Injustice and Humiliation: The treatment Uchiha Setsuna receives in the simulation highlights the theme of unfairness and the consequences of humiliation.

Character Interactions

• Naruto and Uchiha Setsuna: Uchiha Setsuna observes Naruto's struggle with the Clone Technique, showing empathy but also a sense of superiority, as he believes Naruto will never learn it.
• Uchiha Setsuna and Kumogakure: Uchiha Setsuna's interaction with Kumogakure in the Life Simulator reveals the village's despicable treatment of him, fueling his anger and disgust.

Chapter Summary: “Plotting to Steal the Scroll of Seals!”

Key Plot Points and Events

• Uchiha Setsuna observes that the students in his class are overwhelmingly focused on learning ninjutsu, especially the Clone Technique, rather than their regular lessons.
• After more than a month, the students begin forming friendships and social groups:
  • Yamanaka Ino and Haruno Sakura remain friends despite Setsuna’s presence.
  • Akimichi Choji follows Nara Shikamaru, who befriended him after noticing that other children excluded him because of his weight.
• Setsuna reflects on the Akimichi Clan’s political position. Although Torifu Akimichi was one of Tobirama Senju’s disciples, the clan seems to have received far less status and influence than the other disciples’ families. Setsuna wonders whether the Akimichi Clan has been unfairly subordinated to the Nara Clan and the Sarutobi faction.
• During a Transformation Technique assessment, Setsuna fails to perform the Clone Technique. Iruka encourages him, and Setsuna politely accepts the criticism.
• Setsuna thinks about Second Pillar, whom he has killed several times in Life Simulations—with Second Pillar’s consent—after asking whether he would sacrifice himself to hurt Uchiha Itachi following the massacre of the Uchiha Clan. This gives Setsuna increased respect and goodwill toward him.
• Setsuna decides to attempt stealing Konoha’s Scroll of Seals. He knows the task will be much more difficult for him than it was for Naruto, but he views failure as acceptable if he can obtain useful benefits during the attempt.
• To create an opportunity, Setsuna plans to sell Konoha’s intelligence to Kumogakure and provoke a war. He believes Kumogakure is the most likely village to attack because it is powerful, decisive, and led by the aggressive Raikage.
• In the Life Simulation:
  • At six years and one month, Setsuna locates a Kumogakure spy and passes Konoha’s intelligence to him.
  • He investigates Mizuki with Mind Invasion, hoping to learn about the Scroll of Seals, but discovers that Mizuki knows nothing.
  • Kumogakure attacks Konoha, creating the disorder Setsuna needs.
  • The spy is eventually exposed and names Setsuna, but Setsuna’s use of the Transformation Technique prevents Konoha from learning his real identity.
  • As the war intensifies, more Uchiha are sent to the battlefield and suffer heavy casualties.
  • When even older Uchiha students are mobilized and Setsuna expects he may soon be deployed, he decides to act.
  • He learns the Genjutsu technique Firefly and reaches the area near the Hokage Office Building, preparing to begin his attempt to steal the Scroll of Seals.

• Akimichi Choji is shown as socially isolated because of his appearance, despite belonging to a notable ninja clan.
• Iruka remains supportive and encouraging when Setsuna fails the Clone Technique.
• Mizuki is revealed to be useless to Setsuna’s investigation because he never possessed meaningful information about the Scroll of Seals.

Significant Themes

• Social exclusion and prejudice: Choji’s treatment demonstrates how children can be marginalized because of appearance or perceived status, even when they come from established clans.
• Clan hierarchy and political inequality: Setsuna questions why the Akimichi Clan remains subordinate despite its historical importance and connection to Tobirama’s inner circle.
• Manipulation of war and chaos: Setsuna views conflict not as a tragedy alone but as an opportunity to exploit instability for personal advancement.
• Moral ambiguity: His plan involves betraying Konoha and provoking war, showing how far he is willing to go to achieve his goals.
• The difference between appearance and reality: Setsuna deliberately performs poorly, hides his identity with Transformation, and conceals his real abilities and intentions from those around him.
• Fate and simulation: The Life Simulation allows Setsuna to repeatedly test dangerous plans, while his interactions with simulated characters still affect his emotions and judgments.

Character Interactions

• Shikamaru’s friendship with Choji reveals his kindness and challenges the class’s exclusionary behavior.
• Setsuna receives encouragement from Iruka after failing the Clone Technique.
• Setsuna notices Second Pillar’s complicated feelings toward him but chooses not to acknowledge them openly.
• Setsuna’s investigation of Mizuki shows his willingness to invade another person’s mind for information.

Chapter Summary: “Medical Ninjutsu: Eye Transplantation! (Please Vote)”

Key Plot Points and Events

• Uchiha Setsuna reflects on his growing skill with the Life Simulator. He now aims to accomplish several objectives in each simulation rather than pursuing only one.
• After leaving the Ninja Academy, he meets Uchiha Sagiri, who gives him a childish drawing of the two of them together. Sagiri expresses her hope that they will remain happy and close despite the worries that come with growing up. Setsuna reassures her.
• In the next simulation, Setsuna pursues two goals:
  • Investigating explosive tags secretly planted in Konoha’s buildings.
  • Learning Medical Ninjutsu capable of performing eye transplants.
• He successfully infiltrates the Medical Department, studies the technique, and eventually masters eye transplantation after experimenting on animals, humans, and himself.
• At age seven, during the Night of the Uchiha Clan Downfall, Setsuna waits near Fugaku and Mikoto Uchiha’s home. After Itachi kills them, Setsuna examines the bodies but discovers that Fugaku’s eyes have already been destroyed.
• Itachi returns and attacks Setsuna. Although Setsuna, now possessing Elite Jonin-level strength, manages to resist briefly, Itachi’s Mangekyō Sharingan overwhelms him and he dies.
• The simulation confirms Setsuna’s suspicion that Itachi cooperated with Konoha’s leadership in exterminating the Uchiha, since no Konoha ninja came to intervene.
• Setsuna chooses Medical Ninjutsu: Eye Transplantation as his reward instead of the investigation records, believing the records have limited value compared with the future usefulness of the Byakugan.
• In the real world, Setsuna trains with Sagiri in a forest and practices the Uchiha Fire Release technique Hōsenka Tsume Akai. Sagiri praises his performance, though Setsuna modestly notes that other children currently surpass him.

Character Developments

• Uchiha Setsuna: Becomes more strategic and ambitious with the Life Simulator. He obtains the ability to perform eye transplants and begins planning to acquire and implant a Byakugan. His simulation also confirms his growing strength, as he can now briefly challenge Itachi rather than being killed instantly.
• Uchiha Sagiri: Is portrayed as affectionate, hardworking, and emotionally attached to Setsuna. Her drawing and comments reveal her desire to preserve their bond as they grow older.
• Uchiha Itachi: Is depicted as exceptionally powerful and brutally committed to the Uchiha massacre. His willingness to kill Fugaku, Mikoto, and even Izumi contrasts with his refusal to kill Sasuke.

Significant Themes

• Preparation and long-term planning: Setsuna uses simulations to acquire abilities and information gradually, prioritizing tools that will benefit future plans.
• Power versus utility: The Sharingan provides greater direct combat power, while the Byakugan offers superior surveillance, detection, and resistance to genjutsu. Setsuna values the Byakugan as a strategic intelligence tool.
• Betrayal and political conspiracy: The simulation reinforces that the Uchiha massacre was not solely Itachi’s action but involved cooperation with Konoha’s leadership.
• The loss of innocence: Sagiri’s hope for lasting happiness contrasts sharply with Setsuna’s awareness of the violence and tragedy awaiting the Uchiha clan.
• Moral corruption and sacrifice: Setsuna reflects on Itachi’s willingness to kill his family and loved ones, questioning the extremity of his commitment to his mission.
• Identity and hidden potential: Setsuna remains disguised and downplays his current abilities, suggesting that his visible performance does not represent his true strength or ambitions.

Character Interactions

• Setsuna and Sagiri: Their relationship is warm and sibling-like. Sagiri shares her fears and hopes through her drawing, while Setsuna comforts her and later trains alongside her.
• Setsuna and Itachi: Their simulated battle demonstrates the growing gap between Setsuna’s developing abilities and Itachi’s Mangekyō Sharingan. Setsuna can resist but is ultimately defeated.

Chapter Summary

Key Plot Points and Events

• Uchiha Setsuna reflects on the limited importance of academic performance in the ninja world, recognizing that bloodlines, secret techniques, kekkei genkai, and innate talent matter far more.
• During Ninja Tool class, Iruka introduces more difficult exercises involving distant and moving targets. Setsuna observes the others rather than participating immediately, choosing to avoid drawing attention to himself.
• Setsuna struggles internally with his desire to show off and live more openly, but continues suppressing those impulses to avoid being noticed—especially by Uchiha Itachi.
• On his way home, Setsuna encounters Uchiha Izumi, Itachi’s childhood friend. He deliberately ignores her, fearing that interacting with her could draw Itachi’s attention.

• Iruka explains that different ninja serve the village in different ways, including teachers who guide and educate future generations.
• Setsuna internally rejects the lesson as hypocritical, questioning how the Will of Fire could coexist with the Uchiha clan’s oppression and eventual destruction.
• He reflects on Konoha’s treatment of the Uchiha, Orochimaru’s human experiments, and Naruto’s miserable childhood despite Minato’s contributions to the village.
• Naruto and many other students are inspired by Iruka’s speech, while Setsuna views the lesson as effective ideological conditioning.
• After school, Setsuna follows his normal routine before beginning another Life Simulation.

Chapter Summary

Key Plot Points and Events

• Uchiha Setsuna prepares for another Life Simulation, reviewing his available advantages: Izanagi, multiple Three Tomoe Sharingan, Medical Ninjutsu for eye transplantation, Water Transformation, and an Explosive Storage Scroll.
• He realizes the Storage Scroll greatly amplifies the explosive power of the tags inside it—more than ten times their combined strength—but concludes it is unlikely to kill a Kage-level ninja.
• Setsuna considers using the enhanced explosion to destroy the barrier protecting Konoha’s Scroll of Seals, though the plan ultimately fails.
• Since obtaining a Mangekyō Sharingan is one of his few possible paths to Kage-level strength, he decides to target Fugaku Uchiha and imitate Itachi in an attempt to kill him and take his eyes.
• In the simulation, Setsuna creates a diversion by detonating explosive tags near Hokage Rock while another Shadow Clone detonates the Explosive Storage Scroll near the Hokage’s secret chamber. The resulting blast severely damages the building but fails to break the Scroll of Seals’ barrier.
• Setsuna escapes after killing pursuing Anbu, then steals another Storage Scroll and medical supplies as preparation for obtaining more Sharingan.
• After failing to locate Kakashi, Setsuna transforms into Itachi and approaches Fugaku, copying Itachi’s behavior during the Uchiha clan massacre.
• Fugaku immediately recognizes the deception. Setsuna’s Mind Body Switch Technique fails, and Fugaku overpowers him even after Setsuna uses Izanagi.
• Setsuna dies while clutching the Storage Scroll, allowing him to claim it as his reward. Inside are three Three Tomoe Sharingan—two intact and one damaged—and one damaged Byakugan.

Character Developments

• Uchiha Setsuna: Becomes increasingly experimental and ruthless, treating the Life Simulation as a testing ground for dangerous plans. He acknowledges his limited talent and lack of emotional connection to the world as obstacles to naturally awakening the Mangekyō Sharingan. After acquiring more eyes, he gains additional resources but remains frustrated by the limits of using Izanagi without a body like Danzo’s.
• Fugaku Uchiha: Demonstrates exceptional perception and combat ability by instantly seeing through Setsuna’s disguise. His apparent familiarity with Izanagi and lack of surprise raise the possibility that he possesses a special Mangekyō ability or had already detected Setsuna during an earlier simulation.
• Kakashi: Remains an unsuccessful target, as Setsuna cannot locate him during his surveillance.
• Itachi: Functions as the identity Setsuna imitates, particularly his actions during the Uchiha clan downfall, but does not appear directly.

Significant Themes

• Power through experimentation: Setsuna relies on repeated simulations, stolen techniques, transplanted eyes, and explosive tools rather than natural talent.
• The limits of preparation: Even carefully planned schemes fail against stronger opponents, especially when Setsuna lacks complete information about their abilities.
• Identity and deception: Setsuna’s attempt to impersonate Itachi highlights the risks of copying another person without understanding their relationship with the target.
• Moral deterioration: His willingness to kill Fugaku, Anbu, and others for power shows his growing ruthlessness.
• Mystery surrounding Mangekyō abilities: Fugaku’s ability to expose Setsuna and his reaction to Izanagi create a central mystery about the true nature of his Sharingan powers.

Character Interactions

• Setsuna interacts indirectly with Konoha security by creating explosions and fighting the Anbu sent to investigate.
• His main confrontation is with Fugaku, where disguise, Mind Body Switch, and Izanagi all fail against Fugaku’s superior awareness and strength.

Chapter Summary: If Only Itachi Were My Younger Brother!

Key Plot Points and Events

• Uchiha Setsuna completes another Life Simulation in which Orochimaru injects him with Hashirama Cells. The experiment fails catastrophically, causing Setsuna to deform into a sapling and die.
• Given a choice between retaining the failed Hashirama Cell transformation or receiving the item he held at death, Setsuna chooses the latter. He receives two scrolls stolen from the Hōzuki clan residence in Kirigakure.
• Setsuna reviews the information gained from the simulation:
  • Major ninja villages protect important facilities with powerful barrier seals.
  • Konoha has placed an unidentified tracking mark on the Uchiha—or specifically on Setsuna—which allows its forces to locate him after he reenters the Land of Fire.
  • Orochimaru already operates a laboratory in the Land of Fields and is willing to accept Setsuna as an experimental subject.
  • Hashirama Cell transplantation may still be viable if Orochimaru’s techniques improve.
• He considers other possible research targets, including the Gelel Stone, the Box of Paradise, the Loulan Dragon Vein, Zero-Tail, and Gashadokuro. Because Setsuna is not a researcher and is easily tracked in smaller nations, he thinks about bringing someone like Yakushi Kabuto with him in future simulations.
• The scrolls contain Water Release: Water Gun Technique and Water Release: Water Bullet Technique. Setsuna considers the Water Gun Technique especially valuable for long-range assassination when combined with the Byakugan.
• After breakfast, Setsuna goes to train with Uchiha Sagiri. They walk hand in hand, watched from a distance by Second Pillar.
• Setsuna trains cautiously in physical conditioning and shuriken techniques, avoiding anything that might attract suspicion. He continues training through the day, and the following morning begins another Life Simulation before class.

Character Developments

• Uchiha Setsuna becomes more strategic and cautious. He evaluates the risks of Konoha’s surveillance, the limitations of his own abilities, and the value of future alliances and research opportunities.
• His failed Hashirama Cell experiment does not discourage him entirely; instead, he concludes that success may be possible with improved procedures and plans to postpone the experiment in future simulations.
• Setsuna demonstrates growing interest in specialized techniques and assassination methods, particularly using Water Gun Technique with the Byakugan.
• Uchiha Sagiri continues to train alongside Setsuna and shows a close, affectionate bond with him.

• Surveillance and mistrust: Konoha’s hidden mark on the Uchiha reinforces the atmosphere of suspicion and political control surrounding the clan.
• Family and emotional connection: The contrast between Setsuna and Sagiri’s companionship and Second Pillar’s longing for Itachi highlights the importance of sibling closeness.
• Power versus risk: Hashirama Cells promise immense strength but can also result in horrific failure, emphasizing the dangers of pursuing power through experimentation.

Character Interactions

• Setsuna speaks with Uchiha Kayan, who prepares breakfast and reminds him to return by noon.
• Sagiri joins Setsuna for training, briefly returning home to leave her bento before taking his hand and accompanying him.
• Second Pillar observes the pair and compares their closeness to his own relationship with Itachi, wishing that Itachi could have been his younger brother.
• Setsuna’s memories of Teuchi also contrast the ramen-shop owner’s kindness toward Naruto and the Uchiha with the hostility of Konoha’s leadership.
