Chapter Summaries

Chapter Summary: “A Dramatic Battle!”

Key Plot Points and Events

• As the Flower Tree World blooms inside the Uchiha Flame Formation, it releases poisonous pollen. Nadeshiko Saori realizes her petal-based technique cannot disperse it because the pollen is a natural effect rather than ninjutsu.
• Both fighters hold their breath to avoid poisoning. Saori believes Riu will run out of oxygen first, but Riu reveals that Hashirama’s power has greatly enhanced his physical endurance.
• Saori uses her ultimate taijutsu technique, Nadeshiko Style Body Technique Ultimate: Black Qilin, surrounding her fists with dense, black chakra shaped like qilin heads.
• She follows with Flying Flowers, Dancing Shadows, launching an exceptionally fast and intricate close-range assault. Riu initially finds her movement difficult to track, but his Mangekyō Sharingan improves his reactions.
• Rather than relying on his intangibility, Riu chooses to fight Saori directly, meeting her attacks with Senju-style super-strength punches. Their clash becomes an intense, evenly matched taijutsu battle.
• Observers outside the barrier cannot see clearly, but Ao uses his Byakugan to report that the fight is fierce. He notes that Riu’s chakra remains stable while Saori is gradually exhausting herself.
• After two minutes of combat, Saori’s breathing control, chakra, speed, and footwork begin to fail. She admits that Riu has shown her how wide the world is and acknowledges his overwhelming strength.
• Saori refuses to surrender and activates a forbidden technique sealed by the First Nadeshiko Queen: Nadeshiko Forbidden Art: Six Desires in Chaos.
• The technique sends a six-colored mental attack at Riu, capable of randomly intensifying one of a person’s six desires—greed, anger, obsession, appetite, lust, or desire.
• Saori collapses from chakra exhaustion after using the technique. Riu disperses the poisonous pollen with Wind Release and asks what she did to him.
• Saori admits that the technique’s effect is random and should soon manifest. The chapter ends when Riu suddenly displays a beastlike expression, implying that the technique has intensified an embarrassing desire—apparently lust. Saori panics at the result.

Character Developments

• Riu: Demonstrates superior endurance, advanced Sharingan abilities, powerful taijutsu, and confidence. Although he could have used intangibility to win safely, he deliberately fights Saori fairly, showing restraint and respect. His final reaction suggests that Saori’s forbidden technique has affected him.
• Nadeshiko Saori: Proves herself to be an exceptionally powerful fighter, possessing advanced taijutsu, Yin Release, strong chakra control, and several dangerous secret techniques. She recognizes Riu’s superiority but remains determined to fight until every option is exhausted. Her confident demeanor collapses into embarrassment and panic when her forbidden art appears to affect Riu in an unintended way.
• Mei Terumi and Ao: Observe and assess the battle from outside. Ao provides tactical information through his Byakugan, while Mei interprets Riu’s decision to fight physically as evidence of his gentlemanly nature.
• Nadeshiko’s female ninja: Defends Saori’s strength and hopes she can match a Kage-level opponent, though she privately fears Saori may lose.

Significant Themes

• Growth and the limits of strength: Saori realizes that even great power has limits and that she still has room to grow. Riu tells her that her already impressive foundation qualifies her to stand alongside the Kage.
• Fairness and dignity in combat: Riu intentionally avoids using intangibility, choosing a direct contest despite having safer ways to win. This emphasizes mutual respect and the importance of a worthy duel.
• Endurance versus explosive power: Saori relies on a powerful, high-intensity offensive strategy, but maintaining it while holding her breath drains her chakra. Riu’s superior stamina allows him to outlast her.
• Forbidden knowledge and unintended consequences: Saori’s sealed technique is powerful but imperfect. Its random effect creates danger and embarrassment, showing that uncontrolled power can produce unpredictable results.
• Public image and embarrassment: Saori worries that Riu’s altered desire will cause him to lose face as the Shadow, while her own panic reveals how personally and romantically she is invested in his reaction.

Character Interactions

• Riu analyzes Saori’s techniques while fighting her, recognizing the density of her chakra and her use of Yin Release.
• Saori and Riu exchange respectful but competitive remarks, with Saori acknowledging his superiority while refusing to surrender.
• Mei and Ao discuss the battle and Riu’s unusual choice to engage in taijutsu rather than rely on his known intangibility.
• After the battle, Saori explains the forbidden art to Riu and teasingly suggests he may be humiliated in public. When the technique apparently triggers an intense desire in him, her teasing immediately turns into alarm and embarrassment.

Chapter Summary: “A Ballad Carried on the Wind!”

Key Plot Points and Events

• Nadeshiko Saori’s forbidden technique affects Riu, causing his body temperature and sexual urges to rise uncontrollably. Her original intention was to humiliate him publicly and force him to marry into Nadeshiko Village, but the technique produces a much more dangerous situation.
• Fearing that Riu’s loss of control will disgrace herself, Nadeshiko Village, and the Land of Women, Saori attempts suicide. Riu stops her before she can injure herself.

• The Uchiha Flame Formation disappears, and Riu exits while Saori remains stunned. The villagers assume he has won, while Saori realizes how extraordinary his self-control is.

• They return to their room, only to discover Yugao there. She notices their disheveled state and tactfully leaves, promising not to enter without warning again.

• Riu then returns home, leaving the ruined Hidden Rain Village under its endless rain.

• Kakashi and Might Guy return to Hidden Leaf Village after their failed mission against Uchiha Riu. Kakashi has a broken arm and reports that Riu discovered their actions and defeated them.
• Kakashi conceals the true circumstances of their encounter, and Guy supports his story by claiming that Riu spared them because Minato had previously refrained from personally intervening against Orochimaru.
• Minato suspects that Kakashi is withholding information but accepts the explanation. He believes Riu still intends to infiltrate or operate against Konoha independently.
• Guy forgets to report Kurenai’s abnormal condition. Before he can return to Minato’s office, he and Kakashi overhear urgent intelligence: Pain is suspected of destroying Hidden Rain Village.
• Because Konoha’s Root once aided Hanzō in suppressing Akatsuki, Minato fears Pain may retaliate against the village. He places Konoha under martial law and orders all Jōnin to remain inside the village.

  • Six Paths Sage Art, which is currently beyond his reach.
  • Wood Release Sage Art, whose secrets remain unknown and which Hashirama only mastered later in life.
  • Mount Myoboku and Wet Bone Forest, whose sages are unlikely to accept him because of his hostility toward Jiraiya and Tsunade.
• Riu chooses Ryuchi Cave, the source of the snake-based Sage Art connected to Orochimaru’s Cursed Seal research.
• Orochimaru reveals that he has located Ryuchi Cave but has not entered it, since Manda lacks enough influence to grant him access.

Significant Themes

• Pursuit of power: Riu continually seeks new methods of strengthening himself, viewing Sage Art as both an immediate advantage and a foundation for future abilities.

Character Interactions

He balances Kakuzu’s harsh financial management with personal generosity, arranges protection for Shadow Village, and deliberately investigates dangerous supernatural powers instead of simply destroying them. His affection for Xiyang becomes more openly expressed.

Chapter Summary: “The Differences Between the Three Great Sage Arts!”

Key Plot Points and Events

• While traveling toward Ryūchi Cave, Riu asks Orochimaru to explain the differences among the three great Sage Arts.
• Orochimaru describes:
  • Ryūchi Cave’s Mutative Sage Art, which uses Yang Release to transform the body, greatly increasing Body Energy and strengthening techniques such as Wood Release. It allows continuous absorption of natural energy during battle but risks emotional instability if mental and physical energies become unbalanced.
  • Shikkotsu Forest’s Silent Sage Art, based on Yin Release and requiring perfect mental harmony with nature. It grants autonomous, flawless combat reactions, dramatically enhances Mental Energy and ocular techniques, and provides strong resistance to mental interference. However, entering this Sage Mode requires more than ten minutes of uninterrupted meditation.
  • Mount Myōboku’s Harmonizing Sage Art, which balances nature, body, and mind. It offers the most stable and controlled Sage Chakra, requires only about five minutes of meditation, but consumes Sage Chakra quickly unless the user employs frog fusion.
• Riu realizes that Shikkotsu Forest’s Sage Art could solve his greatest problems: the strain placed on his Sharingan and his vulnerability to mental-control techniques. He decides to pursue all three Sage Arts, especially the one from Shikkotsu Forest, even considering forcing his way into the sacred forest if necessary.
• After nearly three months of travel, Riu and Orochimaru reach the area surrounding Ryūchi Cave. They pass through the ruins of the Jūgo Clan’s village, learning that generations of exposure to leaking Sage Power caused the clan’s bodily mutations and ultimately produced the Cursed Seal phenomenon.
• Riu gradually begins sensing natural energy. When they reach Ryūchi Cave’s hidden entrance, he uses his Mangekyō Sharingan and appears able to see the spatial gateway directly.
• Using Kamui, Riu opens a black portal into the secret realm. He and Orochimaru enter Ryūchi Cave together.

Character Developments

• Riu gains a clearer understanding of the strengths and weaknesses of the three Sage Arts and begins planning to master more than one.
• His concern over the long-term damage to his Sharingan becomes more urgent; he fears that his eyes may fail before his eventual battles with Shisui and Itachi.
• Riu’s confidence and ambition are emphasized when he declares that he will obtain Shikkotsu Forest’s Sage Art regardless of the obstacles, even if it requires confronting Tsunade or invading the forest.
• His ability to sense natural energy shows that he is already beginning to adapt to Sage-related power.
• Orochimaru acts as Riu’s instructor and guide, providing detailed knowledge of Sage Arts and revealing his surprise at Riu’s ability to perceive Ryūchi Cave’s hidden entrance.
• Orochimaru remains amused and fascinated by Riu’s unpredictability, remarking that traveling with him is never boring.
• Tsunade is indirectly characterized as too hot-tempered to meet the mental requirements of Silent Sage Art, explaining why she never learned it.
• The chapter briefly notes the birth of Sakura Haruno, placing the journey within the broader timeline of the Naruto world.

Significant Themes

• Balance versus specialization: Each Sage Art represents a different philosophy—physical transformation, mental perfection, or harmony among body, mind, and nature.
• Power and its costs: Every form of Sage Art offers major advantages but includes limitations such as emotional instability, lengthy preparation, or rapid chakra consumption.
• The pursuit of power: Riu is unwilling to accept limitations and intends to collect every useful ability, even if doing so requires challenging established authorities or sacred locations.
• Preserving identity and ability: Riu’s desire to protect his Sharingan reflects his fear of losing the powers and purpose that define him.
• Hidden potential and perception: Riu’s Kamui-enhanced vision allows him to bypass the mystical requirement of a “sincere heart,” suggesting that his unique ocular abilities may let him overcome traditional barriers.

Character Interactions

• Riu and Orochimaru share a teacher-and-student-like discussion while traveling, with Orochimaru explaining Sage Arts and Riu asking perceptive questions.
• Riu challenges Orochimaru’s presentation of Mount Myōboku’s Sage Art as merely moderate, prompting Orochimaru to clarify its exceptional control over natural energy.
• Their conversation reveals mutual respect: Orochimaru recognizes Riu’s growing abilities, while Riu trusts Orochimaru’s knowledge.
• At the hidden entrance, Riu’s use of Kamui shocks Orochimaru, who realizes that Riu’s Mangekyō Sharingan may uniquely overcome the barrier to Ryūchi Cave.
• The two ultimately enter the secret realm side by side, beginning the next stage of Riu’s Sage Art training.

Chapter Summary:

Myriad Nest Snake Cavern

Key Plot Points and Events

• Riu and Orochimaru arrive in Ryūchi Cave through Kamui rather than the normal entrance. Because Riu forced his way in, they are subjected to a far more dangerous trial than the standard sage training process.
• They encounter Manda, Orochimaru’s former summon, who reveals that they have been transported to the Myriad Nest Snake Cavern, a deadly area inhabited by numerous Snake Kings as powerful as himself.
• The snakes attack with swarms of venomous smaller snakes and clouds of poisonous mist. Orochimaru and Riu initially fight back-to-back, but Riu is bitten while protecting Orochimaru and uses Kamui to take them both into his Space-Time Dimension.
• Riu survives the venom because Orochimaru previously modified his body to increase his resistance to toxins. He views the poison as an opportunity: if he can endure Ryūchi Cave’s venom, ordinary poisons will likely never threaten him again.
• After recovering, Riu and Orochimaru return to the cavern and combine Fire and Wind Release techniques, turning the area into a sea of flames and greatly amplifying their attacks.
• Riu uses Wind Cutter to slice through the giant snakes, while Orochimaru immobilizes them with Shadow Snake Hands and paralyzes them with Lightning Release.
• When Manda attacks, Riu traps him under the Sharingan’s control, forcing him to turn against the other snakes. Riu then activates Susanoo, while Orochimaru causes the cavern ceiling to collapse.
• After a prolonged battle, most of the Snake Kings are killed and the rest flee. Manda dies after condemning Riu and Orochimaru to an even worse fate ahead.
• Orochimaru respectfully closes Manda’s eyes, and the two continue searching for the White Snake Sage. Riu remains determined to find her, even if he must tear Ryūchi Cave apart.

Character Developments

• Riu demonstrates both combat ability and self-sacrifice by protecting Orochimaru from the venomous snakes. His willingness to endure the poison also reflects his practical, relentless mindset.
• Riu’s confidence and ruthlessness become more apparent when he decides to exploit the poison as a means of strengthening himself and later controls Manda with the Sharingan.
• Orochimaru shows concern for Riu’s condition and relies on his knowledge of Ryūchi Cave and its poisons. His earlier body modifications prove essential to Riu’s survival.
• Orochimaru displays emotional complexity when he closes Manda’s eyes, acknowledging their former partnership despite their hostile relationship.
• Their teamwork grows stronger as they coordinate elemental attacks and tactical retreats, suggesting increasing trust and cooperation.

Significant Themes

• Trial through adversity: Ryūchi Cave tests intruders through lethal combat rather than conventional instruction.
• Adaptation and survival: Riu treats poison and danger not merely as threats but as opportunities to improve his body and abilities.
• Power and control: The Sharingan’s domination of Manda highlights Riu’s willingness to use overwhelming power and manipulate enemies.
• Loyalty and sacrifice: Riu protects Orochimaru, while Orochimaru supports and prepares Riu for the dangers of the cave.
• Respect amid conflict: Orochimaru’s final gesture toward Manda shows that old alliances can retain meaning even after betrayal and violence.

Character Interactions

• Manda openly insults both Orochimaru and Riu, especially blaming Riu for a previous injury and opposing their pursuit of Sage Power.
• Orochimaru warns Riu about the poison and urges him to retreat into Kamui, while Riu later protects Orochimaru from a surprise attack.
• The two coordinate their Fire, Wind, Lightning, and sealing-style techniques with effective battlefield synergy.
• Riu’s control over Manda turns the summon against his own kind, provoking Manda’s fury and contributing directly to his death.
• Despite Manda’s hostility, Orochimaru mourns their past partnership, while Riu remains focused on their next objective: finding the White Snake Sage.

Chapter Summary: “Six-Separation Maze Formation!”

Key Plot Points and Events

• After leaving the Myriad Nest Snake Cavern, Riu and Orochimaru spend an entire month wandering through Ryūchi Cave’s mist-filled terrain. Because Ryūchi Cave exists in a separate space-time, Riu’s Kamui cannot transport them to the outside world.
• Their food and water supplies nearly run out, forcing them to stop wandering and investigate why they seem unable to reach the cave’s end.
• Orochimaru identifies their predicament as the Six-Separation Maze Formation, an extraordinarily powerful barrier that isolates and disorients living beings. Its strength may rival the Four Red Yang Formation.
• Riu realizes the formation may have a weakness: it appears to affect living creatures, while an Impure World Reincarnation corpse might not qualify as living.
• Riu supplies Hanzō’s severed, decayed arm and a living sacrifice. Orochimaru performs Impure World Reincarnation, resurrecting Hanzō as a controllable corpse.
• Under Orochimaru’s control, Hanzō is used as a guide. Because the formation does not confuse him, he leads Riu and Orochimaru to the hidden barrier wall.
• Orochimaru reveals the wall with mucus, exposing a red barrier. Riu uses Kamui to tear open a hole, but damaging the barrier activates a sealing trap.
• Black phantom snakes drag Hanzō underground, imprisoning his soul within Ryūchi Cave. Riu and Orochimaru escape through the closing hole just in time.
• After traveling through the remaining mist, they reach a magnificent temple marked “Ryūchi Cave.” A Snake Princess informs them that they have passed the trial and that the White Snake Sage awaits them.
• Instead of taking them directly to the sage, she brings them to a boiling pool of poisonous liquid and claims they must bathe in it for three days and three nights as part of the rules. Despite suspecting another trap, Riu and Orochimaru accept the challenge.

Character Developments

• Riu demonstrates patience and adaptability after realizing brute force and ordinary investigation cannot solve the maze. His knowledge of Kamui gives him confidence, but he recognizes the technique’s limitations within Ryūchi Cave.
• Riu also displays tactical creativity by connecting the formation’s possible restriction to living creatures with the nature of Impure World Reincarnation.
• Orochimaru proves his expertise by identifying the barrier formation and successfully performing Impure World Reincarnation under difficult circumstances. His willingness to cooperate closely with Riu continues to strengthen their partnership.
• Hanzō returns as a reanimated corpse, bitterly reflecting on his fallen status and the fact that the man who killed him now controls him. His forced sacrifice ultimately enables Riu and Orochimaru to escape.
• The Snake Princess initially appears welcoming but reveals a sinister, deceptive nature. Her poisonous “hot spring” introduces a new trial and reinforces the danger of Ryūchi Cave.

Significant Themes

• Ingenuity over strength: The maze cannot be overcome through direct power alone; Riu and Orochimaru escape by identifying and exploiting a technical weakness.
• The limits of power: Even Riu’s Kamui and advanced formations are insufficient without understanding the barrier’s structure.
• Life, death, and identity: Hanzō’s reanimation raises questions about whether the undead are living or dead, while his transformation into a puppet emphasizes the loss of autonomy after death.
• Partnership and mutual reliance: Riu and Orochimaru combine Riu’s space-time abilities, Orochimaru’s barrier knowledge, and their willingness to trust one another.
• Trials and deception: Ryūchi Cave’s challenges are presented as tests, but they are also dangerous traps designed to punish carelessness.

Character Interactions

• Orochimaru warns Riu about the barrier’s power and sealing mechanism, while Riu supplies the decisive idea involving Impure World Reincarnation.

• Hanzō confronts Riu about using him after death, but Riu dismisses his complaint by reminding him that his fate resulted from his own choices.
• Riu and Orochimaru remain coordinated throughout the escape, physically maintaining contact with Hanzō to avoid becoming separated.
• Upon meeting the Snake Princess, both men immediately sense danger and silently reinforce their vigilance before accepting the poisonous bath trial.

• Orochimaru warns Riu of the pool’s lethal nature and volunteers to test it first, demonstrating his concern for Riu.

• After half a day, Orochimaru realizes that he has also been weakened by the venom vapor and can no longer use chakra.
• Snake Princess appears and explains that their lack of reverence for Ryūchi Cave triggered the supposedly impossible trial. She pushes Orochimaru into the pool and leaves, believing both men will die.
• While submerged, Riu experiences a dreamlike confrontation with his former self and Obito. He nearly gets pulled back into his original world but resists, reaffirming his determination to remain in the Naruto world and continue living for both himself and Obito’s unresolved desires.

• Orochimaru reveals that he survived by using Izanagi, powered by Senju tissue derived from Riu’s blood and a transplanted Sharingan hidden beneath his armpit.

2. Character Developments

• Orochimaru: He demonstrates sincere loyalty by offering to test the venom for Riu and remaining nearby to rescue him. His preparation of Izanagi highlights his caution, ingenuity, and willingness to experiment, while his concern for his appearance provides comic relief.
• Snake Princess: She embodies Ryūchi Cave’s harsh standards and regards the trial as a punishment for the pair’s disrespect. Her confidence and cruelty emphasize the danger of the Sage Art system.
• Obito/Riu’s Phantom Self: The phantom represents Riu’s buried will to survive and functions as the force that prevents him from being dragged back to his original reality.

3. Significant Themes

• Refusal to submit to fate: Riu’s survival depends not only on power but on his determination to choose his own future.
• Identity and belonging: The mirror sequence explores whether Riu belongs in his old world or the Naruto world, ultimately establishing that he has claimed his new life.
• Friendship and mutual loyalty: Riu and Orochimaru begin as strategic allies but now risk themselves for one another.
• Preparation versus reverence: Orochimaru survives through careful planning, while Ryūchi Cave demands obedience and respect rather than cleverness.

• Instead, Riu’s body absorbs the Sage Power like a bottomless vessel. His Sharingan begins developing serpent-like pupils, suggesting a powerful transformation.
• When the White Snake Sage tries to withdraw, Riu traps her with six Wood Release dragons. The dragons drain a massive amount of Sage Power from her, causing her body to shrink and weaken.
• The chapter ends as Riu’s body begins changing while the Wood Dragons restrain and contain the Sage Power they extracted.

Character Developments

• Riu: Demonstrates exceptional resistance to poison and Sage Power. His defiance, confidence, and hidden Wood Release technique reveal that he is far more dangerous and prepared than the White Snake Sage expected. His body begins adapting to Sage Power rather than being corrupted by it.
• Orochimaru: Successfully earns a temporary Sage Power infusion and shows deference toward the White Snake Sage. He also recognizes the danger of Riu’s situation and warns him when the Sage attempts to overwhelm him.
• White Snake Sage: Initially controls the encounter and intends to manipulate Riu into becoming prey. However, Riu’s absorption ability catches her off guard, and her attempt to kill him leaves her severely weakened.
• Snake Princess: Begins confident in her ability to eliminate the challengers, but becomes shocked when they survive and alarmed when Riu resists the Sage Power.

Significant Themes

• Power versus control: The White Snake Sage assumes that Sage Power belongs exclusively to her and can be used to dominate others, but Riu turns the process against her.
• Defiance of authority: Riu refuses to follow traditional customs such as kneeling, challenging the Sage’s assumption that age and status guarantee obedience.
• Adaptation and exceptional potential: Unlike earlier challengers who transformed into snakes, Riu’s body adapts to Sage Power and actively absorbs it, marking him as an extraordinary individual.
• Hidden strength and deception: Riu conceals his Wood Release until the decisive moment, while Orochimaru survives through an undisclosed forbidden technique.
• The dangers of ambition: The failed challengers, Orochimaru, and Riu all seek power, but the chapter emphasizes that Sage Power can either destroy the unprepared or elevate those capable of mastering it.

Character Interactions

• The White Snake Sage and Snake Princess speak casually about former challengers, revealing their cruel view of humans as disposable “pawns” and food.
• Snake Princess confronts Riu and Orochimaru after believing them dead, but the White Snake Sage silences her when she insults Riu.
• Orochimaru respectfully negotiates with the White Snake Sage and receives her temporary blessing.
• Riu directly challenges the White Snake Sage’s authority, prompting her personal attack.
• Orochimaru warns Riu of the Sage’s true intentions, while Snake Princess mocks him until Riu’s resistance proves her wrong.
• The confrontation ultimately reverses the power dynamic: Riu restrains and drains the White Snake Sage, leaving her weakened as his own transformation begins.

Chapter Summary: “Mutative!”

Key Plot Points and Events

• Riu absorbs the White Snake Sage’s refined Dragon Cave sage power, producing an unstable, preliminary Sage Mode. Six sage-chakra snakes coil around him, and a horn emerges through his mask.
• Although the White Snake Sage threatens to kill him after fulfilling her part of their agreement, Riu prevents a confrontation by proposing an equal strategic alliance between himself and Ryuchi Cave.
• Riu argues that future threats connected to the true origins of the ninja world—and beings from beyond the heavens—will endanger both humans and immortals. He presents himself as someone who understands these dangers and could become the White Snake Sage’s most valuable ally.
• Intrigued by Riu’s confidence and potential, the White Snake Sage spares him and sends him and Orochimaru to Dragon-Transformation Sage Mountain to master Sage Mode.
• At the mountain, Riu’s sage power is so overwhelming that the normally violent snakes flee from him. He begins an extended meditation, while Orochimaru observes and wonders what form Riu’s completed Sage Mode will take.
• The White Snake Sage reveals that Riu is only the second human in decades to impress her enough to reconsider her usual rules. The first was Hashirama Senju, who mastered Dragon Cave Sage Art alongside the arts of Mount Myoboku and Wet Bone Forest, creating the legendary Unrestrained Sage Art.
• After a month of meditation, Riu gains precise control over natural energy. He senses it as an extension of his own body and can gather, disperse, separate, and merge it at will. The chapter ends as his Sage Mode begins to mutate.

Character Developments

• Riu: Demonstrates extraordinary talent, composure, and political intelligence. Rather than relying only on power, he negotiates with the White Snake Sage by appealing to her long-term interests. His mastery of natural energy progresses rapidly, suggesting that his Sage Mode may become something unprecedented.
• White Snake Sage: Initially views Riu as reckless and disposable, but gradually recognizes his unusual potential and foresight. Her hostility fades, and she chooses to “gamble” on his future, comparing him to Hashirama.
• Orochimaru: Remains wary of the White Snake Sage’s power and the danger of losing their sage energy. He is fascinated by Riu’s unique development and increasingly curious about the final form of his Sage Mode.
• Snake Princess: Acts as the White Snake Sage’s attendant and guide. She is shocked by Riu’s abilities and astonished by the revelation of Hashirama’s earlier achievement.

Significant Themes

• Power and control: Riu’s raw sage power is immense, but the chapter emphasizes that true mastery depends on controlling and integrating natural energy.
• Negotiation versus domination: Riu avoids conflict by proposing equality and mutual benefit rather than accepting a subordinate role.
• Long-term alliances: The White Snake Sage is persuaded that temporary human lifespans can still possess lasting value when tied to future threats and strategic cooperation.
• Legacy and exceptional talent: Riu is repeatedly compared to Hashirama, establishing a connection between two rare humans capable of surpassing traditional limits.
• The hidden origins of the world: Riu hints at extraterrestrial or otherworldly forces that may eventually disrupt the ninja world, broadening the story’s larger threat.
• Transformation and evolution: The final “mutation” suggests that Riu’s Sage Mode will differ from established forms and may combine or alter existing sage powers.

Character Interactions

• Riu and the White Snake Sage engage in a tense power struggle that shifts into a wary, potentially mutually beneficial alliance.
• Riu’s bold claims challenge the White Snake Sage’s assumptions about humans and persuade her to spare him.
• Orochimaru witnesses Riu’s transformation and silently compares their paths toward Sage Mode.
• Snake Princess questions the White Snake Sage about Riu, prompting the story of Hashirama’s visit and his creation of Unrestrained Sage Art.

Chapter Summary: Ryuchi Cave Sage Mode, Complete!

Key Plot Points and Events

• Riu completes his Ryuchi Cave Sage Mode after absorbing a massive amount of natural sage power, which merges with the sage energy previously received from the White Snake Sage and the enormous chakra of his Complete Hashirama Body.
• His sage chakra undergoes a qualitative transformation, changing from emerald green to silver. His horn enlarges, his hair lengthens, and nine silver snakes form around him to stabilize the overflowing power.
• The White Snake Sage and Orochimaru are stunned by the unprecedented perfection and strength of Riu’s transformation.
• Riu challenges Orochimaru to attack him with his strongest ability. Orochimaru enters his own powerful Sage Mode, gaining horns, fangs, scaled features, and four sage snakes growing from his back.
• Orochimaru uses an enhanced Sage Art: Wind Release: Ultimate Breakthrough. Riu effortlessly counters it with a water technique, later naming it Sage Art: Water Release: Cloud-Piercing Wave. The attack destroys one of Orochimaru’s sage snakes, though it quickly regenerates by absorbing natural energy.
• Recognizing the immense gap between their Sage Modes, Orochimaru uses his trump card: Sage Art: Eight-Branched Serpent Technique. The gigantic eight-headed serpent absorbs natural power and creates a dark-purple chakra sphere more powerful than a standard Eight-Tails’ Tailed Beast Bomb.
• Riu counters with Sage Art: Fire Release: Super Big-Ball Rasenshuriken, using three of his silver snakes to supply chakra while he focuses on its nature and shape transformation. The two attacks collide in a massive fiery explosion.
• Riu reveals that the explosion was only preparation for a greater technique. He gathers natural lightning from the storm clouds and creates a colossal lightning dragon.
• Rather than directly targeting Orochimaru, Riu directs Sage Art: Lightning Dragon Descends at Dragon-Transformation Sage Mountain. The resulting thunderstorm completely destroys the mountain, demonstrating that Riu had only been testing a fraction of his new power.

Character Developments

• Riu reaches a new level of strength, fully mastering Ryuchi Cave Sage Mode. His silver chakra, nine accompanying snakes, and ability to combine multiple elemental Sage Arts establish him as overwhelmingly powerful.
• He becomes more confident and experimental, calmly naming new techniques and treating Orochimaru’s strongest attacks as opportunities to measure his own abilities.
• Orochimaru reveals an advanced Sage Mode far beyond the version associated with Kabuto, including four regenerating sage snakes and the Eight-Branched Serpent Technique. However, he quickly realizes that even his ultimate technique cannot match Riu’s power.
• The White Snake Sage recognizes Riu as an extraordinary talent capable of achieving a level of sage mastery never before seen in Ryuchi Cave.

Significant Themes

• Power escalation and transformation: Riu’s physical and chakra changes symbolize a dramatic evolution beyond ordinary Sage Mode.
• Mastery versus raw strength: Both fighters possess extraordinary techniques, but Riu’s superior chakra reserves and control allow him to overwhelm Orochimaru.
• Innovation and experimentation: Riu develops and names new techniques during the battle, combining sage energy with Water, Fire, Wind, and Lightning Release.
• Controlled destruction: Riu demonstrates restraint by directing his final attack at the mountain rather than Orochimaru, proving both his dominance and precision.
• Natural energy as a limitless resource: The regenerating sage snakes and continuously absorbed natural power highlight the unique endurance and sustainability of Ryuchi Cave Sage Mode.

Character Interactions

• The White Snake Sage observes Riu’s transformation with awe and acknowledges his unprecedented potential.
• Orochimaru and Riu engage in a respectful but intensely competitive test of strength, with Orochimaru eager to challenge Riu despite recognizing the danger.
• Riu analyzes and comments on Orochimaru’s techniques, while Orochimaru openly praises Riu’s terrifying power.
• Their exchange shifts from a conventional battle to a demonstration of Riu’s overwhelming superiority, ending with Orochimaru witnessing the destruction of Dragon-Transformation Sage Mountain.
