Chapter Summaries

Chapter Summary: “Ultimate Form, Killing Intent Shatters the Sky”

Key Plot Points and Events

• Meruem senses the remaining energy of his dead Royal Guards, Youpi and Neferpitou, across East Gorteau.
• He absorbs Youpi’s scattered flesh and blood, greatly increasing his physical strength.
• He then consumes Neferpitou’s corpse, absorbing her abilities, including Terpsichora, rapid regeneration, heightened perception, and combat instincts.
• After absorbing both Guards, Meruem evolves into an immensely powerful “Super King,” possessing the combined abilities of all three Royal Guards, along with his own intelligence and combat talent.
• His aura becomes so overwhelming that it destroys the surrounding forest, tears open the ground, and parts the clouds.
• Using his vastly expanded En, Meruem locates a black airship carrying Netero, Zeno Zoldyck, and Saitama.
• Rather than attacking immediately, Meruem deliberately prepares himself, compressing his Nen into black armor and building suspense for his revenge.
• On the airship, Saitama casually eats an enormous meal while Zeno and Netero worry that Meruem may have survived.
• Netero suddenly senses Meruem’s terrifying approach and warns the others.
• Meruem arrives at the airship at extreme speed, openly declaring his intent to kill Saitama and leave him without a complete corpse.

Character Developments

• Meruem: Undergoes his final transformation by absorbing Youpi and Neferpitou. He becomes far stronger, gains multiple new abilities, and shifts from a defeated king into an arrogant, vengeful “Super King.” His grief over his subordinates is absent; he views them primarily as sources of power and tools for revenge.
• Neferpitou and Youpi: Even in death, their bodies and remaining energy contribute to Meruem’s evolution. Their loyalty is portrayed as continuing beyond death, though Meruem treats their sacrifice as part of his own advancement.
• Saitama: Remains comically unconcerned with the crisis, focusing entirely on food. He is confident enough to treat Meruem’s resurrection as a minor inconvenience, though he acknowledges that the King appears stronger.
• Netero: Despite his experience and strength, he is overwhelmed by fear and despair after sensing Meruem’s new power.
• Zeno Zoldyck: Maintains a cautious, observant attitude but recognizes that the situation has become nearly hopeless.

Significant Themes

• Power through absorption and sacrifice: Meruem’s evolution depends on consuming his fallen subordinates, emphasizing the Chimera Ant theme of strength gained by incorporating others.
• Revenge and wounded pride: Meruem’s hatred of Saitama is driven less by strategy than by humiliation and the desire to restore his damaged dignity.
• Contrasting seriousness and comedy: Meruem approaches the confrontation with apocalyptic intent, while Saitama is more concerned with eating. This contrast reinforces the absurd imbalance between Saitama’s casual attitude and Meruem’s obsession.
• The meaning of loyalty: Youpi and Neferpitou continue to serve Meruem after death, but their loyalty is portrayed as both devotion and exploitation.
• Overwhelming power: The destruction caused by Meruem’s transformation establishes him as a near-invincible force and raises the stakes for the coming battle.

Character Interactions

• Meruem speaks to Neferpitou’s corpse before absorbing her, calling her his finest subordinate and framing her consumption as a final honor.
• Zeno watches Saitama eat and reflects on the bizarre contrast between Saitama’s childish habits and his world-destroying strength.
• Saitama jokes that he needs to eat enough to fight Meruem if the Ant King revives, treating the threat casually.
• Netero and Zeno react with alarm when Meruem’s aura approaches, while Saitama remains calm until he notices the transformed King.
• The chapter ends with Meruem confronting Saitama directly and promising a brutal death.

Chapter Summary: “The King’s Curiosity, the Bald Man’s Secret”

Key Plot Points and Events

• Meruem suddenly appears inside the cabin after being revived and strengthened by absorbing the power of his three Royal Guards.
• The cabin’s occupants—Zeno, the critically injured Netero, and the staff—expect him to attack immediately. Instead, Meruem becomes fascinated by Saitama, who calmly finishes eating tiramisu despite sensing the Ant King’s presence.
• Meruem sits across from Saitama and observes him in silence, impressed by his extraordinary control over his immense power.
• Saitama casually greets Meruem, offers him dessert, and introduces himself as “a hero for fun.”
• Meruem acknowledges that Saitama previously destroyed him with a single kick, causing him to experience fear of death for the first time. Saitama dismisses the feat as a casual kick delivered because Meruem was about to step on Netero.
• Meruem reveals that he has become over a hundred times stronger after absorbing the Royal Guards and believes no one—including Saitama—can defeat him now.
• Curious about Saitama’s strength, Meruem asks whether he gained it through forbidden Nen, divine medicine, or some nonhuman origin.
• Saitama seriously explains that his training consisted of 100 push-ups, 100 sit-ups, 100 squats, and a 10-kilometer run every day for three years. He also mentions eating regularly, avoiding air conditioning, and losing all his hair.
• The other characters react with disbelief, since Saitama’s routine sounds like an ordinary fitness regimen rather than the secret behind overwhelming power.
• Meruem suspects Saitama is mocking him and rises from the table in anger, ending the chapter on a tense note.

Character Developments

• Saitama: Remains completely calm and indifferent in the face of danger. His casual attitude, straightforward honesty, and absurd confidence emphasize how far beyond everyone else his strength is. He also reveals a sincere, almost comically simple view of his own training.
• Meruem: Shows unusual curiosity and restraint. Rather than attacking immediately, he studies Saitama and openly admits that Saitama once made him fear death. His confidence returns after absorbing the Royal Guards, but his frustration grows when Saitama’s explanation seems impossibly mundane.
• Zeno: Becomes increasingly shocked and intimidated, especially by Saitama’s claim that he defeated Meruem with a “casual” kick.
• Netero: Though near death, remains deeply interested in discovering the source of Saitama’s power and reacts with astonishment to the training explanation.

Significant Themes

• True strength versus perceived power: Saitama’s effortless superiority contrasts with Meruem’s belief that strength must come from exceptional abilities, evolution, or supernatural methods.
• Humility and indifference: Saitama does not treat his overwhelming power as extraordinary, while Meruem views strength as central to identity and authority.
• Curiosity challenging arrogance: Meruem’s pride is unsettled because Saitama’s strength cannot be explained through the systems Meruem understands.
• Comedy amid danger: The chapter places a potentially catastrophic confrontation alongside mundane details such as eating tiramisu, offering dessert, and following a basic exercise routine.
• The limits of rational explanation: Everyone searches for a profound secret behind Saitama’s power, but his simple answer only makes his strength seem more absurd and incomprehensible.

Character Interactions

• Saitama and Meruem: Their conversation shifts from a possible execution to a strange, almost casual interview. Saitama treats Meruem like an ordinary visitor, while Meruem alternates between admiration, curiosity, and irritation.
• Saitama and Netero: Saitama’s earlier kick protected Netero, though Saitama describes the act as incidental rather than heroic.
• Meruem and the observers: Meruem’s presence terrifies Zeno, Netero, and the cabin staff, but their fear is contrasted with Saitama’s complete lack of concern.
• Meruem and his own pride: His discussion with Saitama becomes an internal conflict: he wants to understand Saitama’s power, but the trivial explanation makes him feel mocked and challenges his belief in his own superiority.

Chapter Summary: “Plains Showdown”

Key Plot Points and Events

• Meruem confronts Saitama about his absurd strength and demands to know how he became so powerful. Saitama explains that he trained through an ordinary routine, an answer so simple that Meruem initially suspects he is lying.
• A burst of Meruem’s aura shakes the airship and shatters its windows, but Saitama remains completely unmoved, casually catching a falling shard. This convinces Meruem that Saitama is telling the truth.
• Meruem challenges Saitama to a full-strength battle. Because the airship is too cramped, he proposes fighting in the sky, only to discover that Saitama cannot fly.
• They agree to fight on a broad plain several kilometers away. While Meruem immediately flies there and prepares seriously, Saitama stops in the kitchen to get a dorayaki so he will not become hungry during the battle.
• The people aboard the airship are left stunned by Saitama’s casual attitude toward what may be a world-shaking confrontation. Netero reflects that he has never encountered anyone like him.
• On the plain, Meruem meditates and prepares himself, having absorbed the power of the Royal Guards and reached the peak of his world’s power. Saitama eventually arrives while casually eating his dorayaki and apologizes for being late because the food needed reheating.
• Saitama then mentions that he would like to finish quickly so he will not miss lunch, further frustrating Meruem.
• Meruem launches his strongest speed-based attack, using Neferpitou’s Godspeed and Terpsichora: Zero Hand, unleashing more than a thousand attacks at supersonic speed.
• Despite the overwhelming assault, Saitama does not move and suffers no injury. He even yawns and complains that Meruem’s rapid movements are making him dizzy.
• Realizing that speed is ineffective, Meruem prepares to transform and escalate the battle.

Character Developments

• Saitama: Remains indifferent, relaxed, and comically practical throughout the confrontation. His lack of concern demonstrates his overwhelming confidence and reinforces that he views the fight as a minor interruption to his meals.
• Meruem: Begins with pride and determination, but Saitama’s simple explanation and effortless defenses challenge his understanding of strength. His initial confidence gives way to disbelief, though he maintains his composure and adapts strategically.
• Netero: Watches the encounter with growing awe and anxiety. His long experience with powerful beings makes Saitama’s casual behavior seem even more extraordinary.
• Zeno: Is visibly overwhelmed by Meruem’s aura and speed, recognizing that he would be defeated instantly in the same situation.

Significant Themes

• Absurd simplicity versus extraordinary power: Saitama’s godlike strength comes from an ordinary training routine, contrasting sharply with Meruem’s immense effort, inherited abilities, and absorption of the Royal Guards’ power.
• Composure as a sign of superiority: Meruem prepares carefully and treats the fight as a decisive battle, while Saitama’s boredom and hunger suggest that the difference in their power is enormous.
• The limits of conventional strength: Meruem’s speed and ultimate technique, which should be devastating, have no effect on Saitama, showing that normal measures of power cannot explain him.
• Comedy amid danger: The shattered airship, the impending world-changing battle, and Meruem’s serious preparation are repeatedly undercut by Saitama’s concern with dorayaki and ramen.

Character Interactions

• Meruem questions Saitama’s training and challenges him to prove his strength.
• Their discussion reveals the humorous contrast between Meruem’s regal seriousness and Saitama’s straightforward, almost careless manner.
• Zeno and Netero observe the confrontation from the airship, reacting with fear and amazement.
• During the battle, Saitama casually criticizes Meruem’s fighting style, while Meruem remains focused and begins searching for a way to overcome him.

Chapter Summary: “The Three Royal Guards Become One · The King’s Ultimate Form”

Key Plot Points and Events

• Youpi activates “Infinite Transformation,” expanding into a seven-meter-tall, heavily armored form with enormous scythe-like arms.
• He attacks Saitama with overwhelming physical force, but Saitama stops the scythe with one hand and casually knocks Youpi nearly a kilometer away.
• Meruem then uses Shaiapouf’s enhanced “Ultimate Illusion,” surrounding Saitama with horrifying images of dead civilians and accusing him of failing as a hero.
• Saitama acknowledges the accusations without emotional collapse, simply admitting that he did not save them and promising to continue being a hero and arrive sooner next time. His calm acceptance causes the illusion to disintegrate and severely damages Meruem through backlash.
• Meruem switches tactics, using Neferpitou’s “Terpsichora” to compress his body and launch an extremely fast, precise series of attacks against Saitama’s vital points.
• Despite the speed and lethality of the assault, Saitama dodges every strike effortlessly, often without removing his hands from his pockets.
• Realizing that individual abilities cannot defeat Saitama, Meruem fuses the powers of the three Royal Guards—Youpi’s armor and strength, Shaiapouf’s wings and mental power, and Pitou’s agility and combat instincts.
• In his new ultimate form, Meruem unleashes “Meruem Strike,” a punch carrying his full strength, soul, and pride.
• Saitama catches the devastating punch with one open hand and gently sends Meruem crashing through multiple hills into a mountain, ending the battle.

Character Developments

• Saitama: Remains emotionally detached and overwhelmingly confident, but his response to the illusion reveals a sincere sense of responsibility. He accepts his past failures without excuses and reaffirms his commitment to heroism.
• Meruem: Progresses through increasingly desperate strategies—physical transformation, psychological warfare, speed, and finally total fusion of the Royal Guards’ abilities. His growing frustration turns into cold determination, but he ultimately recognizes that Saitama exists beyond conventional combat logic.
• Netero and Zeno: Serve as observers, repeatedly shocked by Saitama’s ability to withstand and surpass attacks that exceed human comprehension.

Significant Themes

• Overwhelming strength versus unconventional power: Meruem combines every available ability, but none can overcome Saitama’s absurd superiority.
• Acceptance rather than resistance: Saitama defeats the mental illusion not through force, but by calmly accepting guilt and continuing forward.
• The limits of conventional combat: Speed, strength, technique, psychological attacks, and perfect synthesis all fail against Saitama’s anomalous nature.
• Heroism as persistence: Saitama’s promise to arrive sooner suggests that being a hero is defined not by never failing, but by continuing to help others despite failure.
• Pride versus simplicity: Meruem invests his entire identity in one ultimate attack, while Saitama treats the battle as an interruption before ramen.

Character Interactions

• Saitama and Meruem: Their battle escalates from physical confrontation to mental warfare and finally to a clash of ultimate forms. Meruem repeatedly tries to understand and overcome Saitama, while Saitama responds with casual observations and minimal effort.
• Saitama and the illusion’s victims: The dead accuse him of failing them, but instead of denying responsibility, Saitama admits it and recommits to being a hero.
• Netero and Zeno observing Saitama: Both are stunned by Saitama’s ability to stop Youpi’s transformed attack, ignore the mental assault, evade Meruem’s ultimate speed, and catch his final punch.
• Meruem and the Royal Guards’ abilities: Meruem internalizes and combines the strengths of Youpi, Shaiapouf, and Neferpitou, creating a final form that symbolizes the complete union of the three Royal Guards.

Chapter Summary: Legacy of the Dark Continent

Key Plot Points and Events

• As Netero prepares to speak aboard the airship, a nearby mountain begins to tremble and split open. Ancient dark-purple fluid seeps from its cracks, producing a scent Netero recognizes from the Dark Continent.
• The Chimera Ant King emerges in a transformed state. No longer merely a powerful being, he has awakened his Dark Continent heritage and becomes the “Egg of the Dark Continent,” a massive disaster-level creature covered in shifting runes, black wings, tentacles, and three star-reflecting eyes.
• The creature releases Life Plunder, an invisible wave that drains life from everything it touches. Plants wither, stone decays, and several airship operators rapidly age. Netero orders the airship to gain altitude.
• Saitama is completely unaffected by the life-draining attack. The Ant King then traps him in an alternate-space technique called Dark Domain, but Saitama escapes with a single Normal Punch, damaging the creature’s core.
• The Ant King regenerates by stealing vitality from the surrounding land, leaving the battlefield as a barren wasteland. Saitama becomes angry at the destruction, particularly because the creature has “stripped the whole place bare.”
• The Ant King attacks by splitting into dozens of monstrous forms, but Saitama destroys them all with Consecutive Normal Punches.
• Realizing that Saitama’s next attack will kill him, the Ant King’s instincts overwhelm him with fear. He flees toward the Dark Continent in the form of dark-purple light.
• Saitama is puzzled by the retreat and mainly regrets that the Ant King escaped without paying for his ramen.
• Netero and Zeno survey the dead land and recognize that the Ant King’s return may bring an even greater threat. Netero thanks Saitama by offering him food, and Saitama happily requests extra roast pork.
• As the heroes leave, a remnant of dark-purple mist burrows into the earth and whispers the name “Nanika,” hinting at a continuing connection to the Dark Continent and a future danger.

Character Developments

• The Ant King evolves from a powerful Chimera Ant into a primal Dark Continent disaster. His abilities become environmental and life-draining rather than merely physical, but he also discovers fear for the first time when confronted by Saitama.
• Saitama remains overwhelmingly powerful and unaffected by the Ant King’s supernatural abilities. However, he shows a rare moment of moral anger when he sees the land being consumed and stripped of life. His mundane concern about ramen continues to contrast humorously with the scale of the battle.
• Netero demonstrates his deep knowledge of Dark Continent threats and immediately recognizes the significance of the Ant King’s transformation. He shifts from confidence to grave concern and accepts that the danger may not be over.
• Zeno experiences instinctive fear toward the awakened creature, emphasizing how far beyond ordinary monsters the Ant King has become. His later exchange with Netero reinforces the seriousness of the threat.

Significant Themes

• Nature as a source of terror: The Dark Continent’s power is portrayed as ancient, alien, and fundamentally beyond human understanding.
• Life and exploitation: The Ant King’s abilities consume life itself, turning the environment into a dead wasteland and showing the destructive consequences of unchecked power.
• Predator and prey: Despite the Ant King’s transformation into an apex predator, Saitama becomes the natural enemy that triggers his first experience of genuine fear.
• Power versus responsibility: Saitama’s immense strength is paired with disapproval of needless destruction, suggesting that his sense of justice extends beyond defeating enemies.
• The persistence of hidden threats: The final mist and whispered reference to Nanika imply that defeating or driving off the Ant King has not eliminated the larger Dark Continent danger.

Character Interactions

• Netero and Zeno jointly recognize the Ant King’s transformation and react with fear and concern.
• The Ant King repeatedly tests his abilities against Saitama, but each attack fails, revealing the immense gap between them.
• Saitama’s anger at the ruined land creates the emotional turning point before his decisive counterattack.
• Netero later offers Saitama food as thanks, while Saitama responds with enthusiasm about ramen and extra pork, providing comic relief after the catastrophic battle.

Significant Themes

• Comedic indifference versus cosmic danger: Saitama treats catastrophic battles and unknown superhuman threats as secondary to his hunger, creating contrast with everyone else’s fear.
• The limits of comprehension: The group has witnessed powerful beings before, yet the new opponent produces a fundamentally different terror—an instinctive sense of being watched by a superior predator.
• Fame and spectatorship: Saitama’s companions choose to stay not only out of loyalty but also because witnessing his battles is a once-in-a-lifetime opportunity.

• He reveals that he has spent ten years traveling through time, enduring torment and consuming terrifying creatures in preparation for revenge against Saitama.
• Meruem attacks first, moving too quickly for Genos’s systems to track. Saitama blocks the blow but is forced back for the first time, recognizing Meruem’s extraordinary growth.
• The two engage in a devastating close-range battle, destroying the arena, shattering its protective barrier, and sending spectators into panic.
• After exchanging numerous powerful blows, they separate. Saitama realizes Meruem could not have reached this level through physical training alone.
• Meruem reveals a mysterious black mark and declares that his strength came from a dangerous power obtained from the deepest reaches of the Dark Continent. He prepares to demonstrate its full power.

Character Developments

• Saitama: Remains casual and uninterested in spectacle, but becomes genuinely surprised and intrigued when Meruem withstands his attacks and forces him backward. He begins questioning the source of Meruem’s power.
• Meruem: Has evolved from a defeated Ant King into a hardened, vengeful warrior. Years of pain, temporal displacement, survival, and sacrifice have intensified his hatred of Saitama and driven him to acquire forbidden power.
• Genos: Displays heightened vigilance and analytical focus, but his advanced tracking systems are unable to measure or follow Meruem’s movements.
• Bang: Recognizes the seriousness of the threat and remains ready to respond.
• King: Appears outwardly composed but is privately terrified, using his game controller to manage his anxiety.
• Gon and Killua: Immediately sense the overwhelming danger of Meruem’s aura, with Killua instinctively protecting Gon.

Significant Themes

• Revenge and obsession: Meruem’s entire transformation is motivated by his humiliation and defeat at Saitama’s hands.
• Sacrifice for power: Meruem’s strength comes at an unspecified but clearly enormous cost, suggesting a dangerous bargain or corruption.
• Time and endurance: His decade-long journey through time and the Dark Continent emphasizes the lengths he is willing to endure for revenge.
• Godlike conflict in a mortal world: The battle’s scale surpasses ordinary combat, turning the arena into a fragile setting for a clash between near-divine beings.
• Contrast between seriousness and absurdity: Meruem treats the confrontation as the culmination of years of suffering, while Saitama remains focused on food and finishing quickly.

Character Interactions

• Saitama and Meruem: Their reunion is defined by extreme contrast: Saitama casually calls Meruem “little ant,” while Meruem responds with intense hatred and a vow to destroy him. Their punches reveal that Meruem is now strong enough to challenge Saitama directly.
• Genos, Bang, King, Gon, and Killua: Their reactions establish the immense danger of the battle. All recognize that Meruem’s power is beyond normal human or Nen-based standards, though each responds differently—through analysis, readiness, fear, or protective instinct.
• Meruem and the spectators: His arrival alone overwhelms the audience, demonstrating that his presence is itself a weapon before the fight even begins.

Chapter Summary: “The Evolution of the Rental Pod”

Key Plot Points and Events

• Saitama and Meruem clash in Heaven’s Arena, with their punches damaging the supposedly indestructible alloy ring.
• During their first collision, Saitama realizes that Meruem is not merely blocking or stealing his energy—he is directly plundering a small amount of power from Saitama’s body through physical contact.
• Meruem reveals the Rental Pod, a machine originally belonging to the deceased Chimera Ant squadron leader Leol. Genos explains its rules:
  • The user must know or witness another person’s ability.
  • They must perform a task acknowledged by that person and receive the phrase, “You owe me one.”
  • The ability is stored as a receipt and can be borrowed for one hour.
  • If the original owner dies, the receipt should disappear.
• Genos identifies a major contradiction: Leol was killed by Saitama, so the Rental Pod should no longer exist. Meruem explains that Leol’s death allowed him to acquire and evolve the ability.
• Meruem activates the abilities of the three Royal Guards:
  • Neferpitou’s Terpsichora: Zero, which predicts Saitama’s movements.
  • Youpi’s Transformation Hardening, which grants immense physical power and armor.
  • Shaiapouf’s Scale Powder Clones, which creates endlessly regenerating, fully powerful duplicates.
• Meruem’s clones overwhelm Saitama and spread powder intended to interfere with his nerves and perception. Saitama destroys them with consecutive normal punches, but each physical blow allows Meruem to absorb more of his strength.
• Meruem reveals that the Rental Pod has evolved beyond borrowing Nen. In its first evolved stage, it can steal an opponent’s physical energy through contact.
• Combining the Royal Guards’ powers with Saitama’s stolen strength, Meruem launches the Black Spot Hardening Fist. The attack sends Saitama crashing through five reinforced walls, marking the first time Saitama has been visibly overpowered.
• Saitama survives without serious injury and emerges more determined than before. Meruem then merges the Rental Pod into his body and announces that he is about to reveal its even more powerful, “absolute Plunder” form.

Character Developments

• Meruem grows increasingly confident and predatory. He views Saitama’s strength as a resource to consume and demonstrates that he has transformed Leol’s relatively limited ability into a much more dangerous power.
• Saitama shifts from casual confidence to genuine focus. Although initially confused by the energy theft, he becomes serious after Meruem’s attack proves capable of overpowering him.
• Genos provides crucial technical analysis, identifying both the Rental Pod’s rules and the contradiction surrounding Leol’s death. His instinct is to intervene when Saitama is injured.
• Bang demonstrates his experience and judgment by stopping Genos from rushing into the fight, recognizing that Saitama remains capable of continuing.

Significant Themes

• Adaptation and evolution: Meruem’s transformation of the Rental Pod reflects the theme of abilities evolving beyond their original limits.
• Power as consumption: Meruem treats Saitama’s strength as something to devour, turning every attack against its source.
• The danger of direct confrontation: Saitama’s usual strategy—overwhelming enemies with powerful punches—becomes dangerous because physical contact empowers Meruem.
• Limits of invincibility: For the first time, Saitama is knocked backward and visibly challenged, creating a major disruption to his established image of absolute superiority.
• Knowledge versus brute force: Meruem’s predictive abilities and layered strategy allow him to exploit Saitama’s straightforward fighting style.

Character Interactions

• Saitama and Meruem: Their battle becomes both physical and psychological. Meruem taunts Saitama, mocks his reputation as an undefeatable fighter, and deliberately encourages him to attack so he can steal more power.
• Genos and Saitama: Genos reacts protectively when Saitama is blasted through the arena walls, showing his loyalty and concern for his teacher.
• Genos and Bang: Bang restrains Genos and urges him to observe rather than intervene, emphasizing the seriousness and unpredictability of the battle.
• Meruem and the Royal Guards’ abilities: Though the Guards are not physically present, Meruem uses their powers as extensions of his own, combining them into a single coordinated combat system.
• Meruem and Leol: Leol’s death becomes the foundation for Meruem’s new power. Meruem’s use and enhancement of the Rental Pod turns Leol’s former ability into a weapon capable of challenging Saitama.

Chapter Summary

Key Plot Points and Events

• The chapter reveals what happened after Leol’s apparent death. The Rental Pod revived him by absorbing a trace of Saitama’s power, transforming it into an immense physical force.
• Because Saitama had indirectly “owed” Leol his life, the Rental Pod treated that power as an advance payment. Leol gained strength on Saitama’s level and became determined to overthrow Meruem.
• Ten years later, Meruem returns from the Dark Continent after devouring Zobae, an action that transforms his body beyond normal physical laws. He emerges with greater size, six black-scaled wings, and overwhelming regenerative abilities.
• Leol pledges loyalty to Meruem but immediately betrays him, attacking with continent-shattering power. Although the blow destroys half of Meruem’s body, Meruem instantly regenerates and evolves beyond the attack’s effectiveness.
• Meruem uses “Gene Dominance,” an instinctive command rooted in Chimera Ant biology, to paralyze and control Leol. He forces Leol to surrender his body and then devours him, absorbing both the borrowed Saitama power and the Rental Pod.
• Meruem explains that he has rewritten the Rental Pod’s rules. It can now steal not only energy through contact but also the original source of that energy through a debt-based power called “Absolute Plunder.”
• Claiming that Saitama inherited Leol’s debt, Meruem begins draining Saitama’s strength from a distance. When Saitama launches a Serious Punch, Meruem nullifies it by declaring, “Repay the debt.”
• Meruem then unleashes Gene Dominance across Heaven’s Arena, forcing nearly everyone present to collapse in terror. Saitama remains physically unaffected but continues losing power.
• The chapter ends with Meruem preparing to take the “final debt” by reaching for Saitama’s head.

Character Developments

• Meruem: Evolves from an already powerful king into a transcendent being capable of regeneration, biological domination, energy theft, and manipulation of causality-like debts. His confidence becomes absolute as he gains control over the Rental Pod.
• Leol: Experiences a temporary rise from defeated Squadron Leader to overwhelming powerhouse, fueled by borrowed Saitama energy. His ambition and betrayal lead directly to his destruction, emphasizing that his strength cannot overcome Meruem’s superior evolution and authority.
• Saitama: Faces his first apparent combat disadvantage. His Serious Punch is neutralized, and his strength is actively drained, challenging his usual invincibility.
• Bang and Genos: Their reactions establish that Meruem’s transformation has surpassed ordinary power increases and reached an entirely new level.

Significant Themes

• Power and its limits: Leol gains seemingly limitless strength but is still helpless before Meruem’s superior nature and abilities.
• Debt and exploitation: The Rental Pod turns gratitude into an enforceable obligation, allowing Meruem to weaponize Saitama’s past actions against him.
• Inheritance and ownership: Meruem claims that everything possessed by the Chimera Ants—including bodies, souls, abilities, and borrowed power—ultimately belongs to him.
• Evolution beyond physical law: Meruem’s Dark Continent transformation represents a shift from conventional strength to an existence governed by entirely different rules.
• Hubris and betrayal: Leol’s confidence leads him to challenge the king, but his rebellion only results in Meruem acquiring even greater power.
• The reversal of certainty: Saitama’s normally unstoppable attacks fail, creating a rare situation in which he must confront an opponent who can negate rather than withstand his strength.

Character Interactions

• Meruem and Leol: Their relationship shifts from king and subordinate to predator and prey. Leol kneels in apparent loyalty, then attacks, but Meruem reasserts biological and spiritual control before consuming him.
• Meruem and Saitama: Their conflict becomes centered on debt rather than direct physical combat. Meruem argues that Saitama’s power belongs to him because he inherited Leol’s claim, while Saitama attempts to resist through sheer force.
• Meruem and the spectators: Meruem’s Gene Dominance reduces the arena’s living beings to helpless submission, demonstrating the psychological and biological reach of his authority.

Chapter Summary: The King Who Severed His Own Arm

Key Plot Points and Events

• Meruem attempts to use his causality-based Rental Pod/Plunder ability on Saitama, intending to drain Saitama’s overwhelming strength through their supposed “debt” connection.
• Saitama casually catches Meruem’s wrist, completely halting the ability. Instead of draining Saitama, the Plunder power rebounds violently, siphoning Meruem’s own Nen and energy.
• To escape, Meruem severs his own right arm while Saitama is holding it. His arm regenerates almost instantly, demonstrating his extraordinary biological abilities.
• The audience, commentator, Genos, Killua, and Gon are stunned that Meruem’s supposedly absolute ability has failed.
• Meruem realizes that Saitama did not technically break the Rental Pod’s rules; Saitama’s power simply exists on such a vastly higher level that the ability cannot affect him.
• Meruem abandons indirect tactics and attacks Saitama physically with extreme speed, his tail stinger, bladed limbs, punches, kicks, and Nen projectiles.
• Despite Meruem’s furious three-minute assault, Saitama remains unharmed, barely moving and even yawning from boredom.
• When Saitama announces that it is now his turn, Meruem destroys and absorbs the Rental Pod, consuming its remaining essence, along with Leol’s memories and abilities.
• The chapter ends as Meruem evolves again, surrounding himself with a terrifying dark-violet aura associated with the Dark Continent and promising to reveal his “true power.”

Character Developments

• Saitama: Remains calm, casual, and nearly invulnerable. His power is revealed to be so immense that even an ability designed to rewrite causality cannot interact with it. His attitude becomes slightly colder after Meruem tries to exploit him.
• Meruem: Suffers a major blow to his pride and confidence. Forced to sacrifice his own arm, he recognizes that his greatest ability is insignificant against Saitama’s overwhelming strength. His humiliation turns into rage, driving him toward a more desperate and powerful evolution.
• Genos: Confirms through his sensors that Saitama’s energy has not changed and that the Rental Pod is completely ineffective against him, reinforcing his absolute faith in his teacher.
• Killua: Uses his understanding of Nen to analyze the failure of Meruem’s ability. He correctly identifies that Saitama has not violated the rules; rather, the ability is simply too weak to impose those rules on him.
• Gon: Quietly observes Saitama’s unwavering strength and gains renewed resolve from it.
• Meruem and Leol: Meruem fully consumes the Rental Pod and Leol’s remaining abilities and memories, treating them as raw material for his next transformation.

Significant Themes

• Absolute strength versus complex abilities: Meruem’s elaborate causality-based power cannot compete with Saitama’s overwhelming physical superiority.
• The limits of rules: The chapter emphasizes that abilities and systems only matter when they can affect the target; Saitama’s power exists beyond the framework governing Nen and causality.
• Pride and humiliation: Meruem’s identity as an invincible king is shaken when he is forced to maim himself and flee.
• Adaptation through sacrifice: Meruem sacrifices his arm, abandons his strategy, destroys the Rental Pod, and absorbs its essence in pursuit of greater power.
• Composure versus desperation: Saitama remains relaxed and bored while Meruem grows increasingly frantic, furious, and desperate.
• Evolution and escalation: Meruem’s defeat does not end the confrontation; it triggers a new transformation and raises the stakes for the coming battle.

Character Interactions

• Saitama and Meruem: Their central conflict shifts from an attempted ability-based victory to a direct confrontation between Meruem’s rage and Saitama’s effortless superiority. Saitama’s statement, “I don’t owe you anything,” directly undermines Meruem’s debt-based strategy.
• Meruem and the audience: Meruem’s failed Plunder ability shocks the spectators and destroys the aura of invincibility surrounding him.
• Genos and Saitama: Genos enthusiastically analyzes the battle and confirms that Saitama remains completely unaffected.
• Killua and Gon: Killua interprets the mechanics of Meruem’s failed ability while Gon watches Saitama as a source of inspiration and determination.
• Meruem and Leol’s power: Meruem consumes the Rental Pod and Leol’s residual abilities, converting his former tool into fuel for his next evolution.

Chapter Summary: The Black Saitama

Key Plot Points and Events

• Meruem releases an immense dark-purple Nen aura throughout Heaven’s Arena, cracking the glass walls and overwhelming spectators with its pressure. His power appears to surpass even Boros’s peak.
• Genos prepares to attack, but the arena’s rules prevent him from intervening. Netero recognizes Meruem’s energy as connected to the Dark Continent, revealing that Meruem has fused a disaster source into his genes.
• Meruem unveils his ultimate technique, the Seed of Plunder, created by combining the Proliferation Disaster with his existing power. The technique can copy an opponent’s strength, speed, instincts, and soul without requiring a contract.
• The Seed is destroyed by Saitama’s Consecutive Normal Punches, but it transforms into an invisible black mist that enters Saitama’s body and begins draining and copying his power.
• Rather than resisting, Saitama deliberately inhales the remaining mist. The Plunder substance reacts violently to something within him, forcing it to flee.
• The substance then forms a perfect black duplicate of Saitama, complete with his appearance and abilities. The duplicate kneels before Meruem and transfers Saitama’s power into him.
• Meruem transforms into a gigantic, black-scaled, winged version of himself, greatly amplifying his aura and strength. He orders Black Saitama to attack the original.
• Black Saitama launches a punch with Saitama’s exact speed and power. Saitama meets it with his own fist, ending the chapter at the moment of their collision.

Character Developments

• Meruem: Reaches a new level of arrogance and power. By successfully plundering Saitama’s abilities, he believes he has finally obtained an unbeatable advantage. His physical transformation reflects his fusion with the Dark Continent’s disaster power.
• Saitama: Remains calm and almost amused despite facing an ability designed to steal his entire power and soul. His unusual reaction to the Plunder mist suggests that his body or strength possesses unknown properties capable of overwhelming the technique.
• Black Saitama: Emerges as a seemingly complete duplicate of Saitama, but without individuality or emotion. He is entirely obedient to Meruem and functions as a weapon against his original.
• Genos: Shows intense loyalty and readiness to break the rules to protect Saitama, though he is forced to hold back because firing could endanger the arena.
• Gon and Killua: React with fear and helplessness, recognizing the overwhelming danger posed by Meruem’s new power.
• Netero: Demonstrates his knowledge of the Dark Continent and remains cautious, pointing out that Saitama’s true limits are still unknown.

Significant Themes

• Power and imitation: Meruem attempts to overcome Saitama not merely by matching him, but by copying and weaponizing his identity and abilities.
• The unknown limits of strength: Although Meruem believes he has acquired everything that makes Saitama powerful, Netero and Saitama’s reactions imply that Saitama may possess qualities that cannot be copied.
• Control versus individuality: Black Saitama looks and fights like the original but lacks his personality, highlighting the difference between possessing someone’s power and possessing their true self.
• Escalation and spectacle: The destruction of the arena, the audience’s panic, and Meruem’s transformation emphasize the increasingly godlike scale of the battle.
• Confidence versus composure: Meruem’s confidence borders on arrogance, while Saitama remains casual and emotionally unaffected, creating tension over whether Meruem’s apparent victory is genuine.

Character Interactions

• Meruem and Saitama: Meruem taunts Saitama and attempts to prove that copied power makes him unbeatable. Saitama responds with confusion and humor rather than fear.
• Meruem and Black Saitama: Black Saitama submits completely to Meruem, who treats the duplicate as a personal weapon and orders it to kill the original.
• Genos and Saitama: Genos urgently warns Saitama and prepares to intervene, demonstrating his unwavering devotion even though he cannot legally attack.
• Netero, Gon, and Killua: Their reactions establish the danger of Meruem’s technique while also preserving hope that Saitama may still have an unknown advantage.
• Saitama and Black Saitama: Their confrontation becomes a literal battle between the original and a supposedly perfect copy, culminating in their identical punches colliding.

“Three Knockdowns” — Chapter Summary

Key Plot Points and Events

• Saitama and Black Saitama exchange identical punches, creating shockwaves that damage Heaven’s Arena. Although their power and speed appear evenly matched, Black Saitama’s body begins developing cracks from the repeated impacts.
• Genos analyzes the copy and discovers that its structural stability is weakening faster than its black substance can repair it. Gon realizes that Black Saitama lacks the original’s true regenerative durability, while Killua suspects Meruem is waiting for an opportunity to attack.
• Meruem confirms this strategy by studying Saitama’s movements and exploiting his distraction. He launches a surprise attack from behind using his Nen-enhanced wings, striking Saitama into a ten-meter-deep crater.
• The spectators fear Saitama has been defeated, but he is unharmed. His only concerns are that one of his geta has been broken and that his custom jumpsuit has been torn, costing him money to replace.
• Meruem is unsettled by Saitama’s complete lack of injury. Before Saitama can recover, Meruem orders Black Saitama to continue the assault, and the copy immediately attacks again.

Character Developments

• Saitama: Demonstrates overwhelming physical durability and remains emotionally detached from the supposedly devastating attack. His main distress concerns the damage to his clothes and footwear, reinforcing his mundane, deadpan personality.
• Black Saitama: Initially appears identical to Saitama in strength, speed, and technique, but repeated impacts expose its inferior structural stability. Its regeneration is unable to keep pace with the damage.
• Meruem: Shows strategic patience and growing frustration. Rather than relying solely on strength, he studies the battle and coordinates a surprise attack with the copy. Saitama’s survival begins to challenge his confidence.
• Genos: Provides crucial technical analysis, identifying the copy’s weakening structure and warning Saitama about Meruem’s attack.
• Gon and Killua: Gon reacts emotionally and focuses on the copy’s weakness, while Killua correctly recognizes that Meruem is planning an unfair tactical maneuver.

Significant Themes

• Authenticity versus imitation: Black Saitama can reproduce Saitama’s movements and apparent power, but it cannot replicate his fundamental durability.
• Limits of copying power: The copy possesses Saitama’s techniques but not the complete reality of what makes him nearly invulnerable.
• Strategy against overwhelming strength: Meruem attempts to overcome Saitama through teamwork, timing, and surprise rather than direct combat.
• Comedy amid extreme violence: The destruction of the arena is treated dramatically by everyone except Saitama, whose concern over a broken sandal and torn clothing undercuts the seriousness of the fight.
• Meruem’s shaken confidence: Saitama’s survival exposes the limits of Meruem’s copied power and forces him to reassess the battle.

Character Interactions

• Saitama and Black Saitama mirror each other in combat, making the fight appear perfectly balanced while revealing the copy’s hidden weakness.
• Genos supports Saitama through battlefield analysis and a warning about Meruem’s ambush.
• Gon and Killua interpret the battle differently, with Gon emphasizing the copy’s lack of regeneration and Killua identifying Meruem’s larger plan.
• Meruem uses Black Saitama as a distraction and attacks Saitama from behind, then immediately commands the copy to resume the assault after Saitama survives.

Chapter Summary: “Saitama Lost?”

Key Plot Points and Events

• Saitama blocks Black Saitama’s punch, but Meruem launches a surprise attack from behind, driving him deeper into the crater.
• Although Meruem’s second strike hits Saitama directly along the spine, Saitama rises again, largely unharmed. His main complaint is that his expensive yellow suit has been torn.
• Meruem and Black Saitama coordinate a pincer attack. Saitama blocks both attacks but cannot defend against Black Saitama’s knee, which strikes his chest and sends him through the arena into a deep trench.
• Saitama is buried beneath twisted safety netting and rubble. After waiting twenty seconds without seeing movement, Meruem concludes that Saitama has lost consciousness.
• Meruem publicly announces that humanity’s strongest individual has been defeated. He proposes allowing humans to live in controlled settlements in exchange for labor and the regular surrender of “high-quality individuals.”
• He intends to use Saitama’s combat data to create additional guards for suppressing regions that resist his rule, and plans to make Saitama the first such guard once he awakens.
• The spectators are overwhelmed by fear, while Genos prepares to attack Meruem. Netero stops him, insisting that the battle is not over.

Character Developments

• Saitama: Remains physically extraordinary and almost entirely uninjured despite three devastating attacks. His casual irritation over his ruined clothing emphasizes his usual indifference, but his apparent defeat creates uncertainty about his limits.
• Meruem: Becomes increasingly confident and analytical. He treats Saitama’s defeat as a logical conclusion rather than a triumph, revealing his cold, managerial approach to conquest and humanity.
• Black Saitama: Works in perfect coordination with Meruem and shows regenerative abilities as the cracks in his arms repair themselves. He remains silent and emotionless, functioning as a powerful combat duplicate.
• Genos: His loyalty and emotional dependence on Saitama become evident. Fear overrides his rational systems, and he immediately prepares to risk himself in retaliation.
• Netero: Maintains composure and strategic judgment. Rather than allowing an emotional counterattack, he recognizes that Saitama may still be capable of continuing.
• Gon and Killua: Both react with alarm—Gon openly worries, while Killua silently watches the ruins, visibly tense and distressed.

Significant Themes

• The appearance of defeat versus reality: Saitama’s silence convinces Meruem and the audience that he has been defeated, but Netero’s warning suggests that appearances may be misleading.
• Rationalized oppression: Meruem presents slavery, forced labor, population control, and the surrender of individuals as an orderly administrative system rather than cruelty.
• Power and arrogance: Meruem’s confidence comes from carefully observing Saitama’s apparent incapacitation, but his certainty may reveal a dangerous underestimation.
• Loyalty and hope: Genos’s faith in Saitama contrasts with the audience’s despair, while Netero preserves the possibility that the fight is not finished.
• Humanity as a resource: Meruem views people not as individuals but as labor, breeding stock, combat data, and strategic assets.

Character Interactions

• Meruem and Black Saitama coordinate their attacks, combining speed, timing, and positioning to overwhelm Saitama.
• Meruem addresses the entire human audience as a defeated population and dictates terms for their survival.
• Genos attempts to attack Meruem in defense of Saitama, but Netero physically restrains him.
• Gon expresses fear for Saitama, while Killua silently shares the tension.
• Netero’s final statement challenges Meruem’s conclusion and keeps open the possibility that Saitama will rise again.

Chapter Summary: “The Most Expensive Punch”

Key Plot Points and Events

• After enduring Meruem’s third attack—an impact equivalent to roughly 120 tons of TNT—Saitama emerges from the rubble almost completely unharmed.
• He is more concerned about his destroyed clothes and missing sandals than the devastating attack. He calculates the damage at five thousand Japanese yen.
• Meruem is deeply unsettled. His attack should have incapacitated or killed any known creature, yet Saitama recovers after only twenty seconds without even a scratch.
• Saitama’s attitude shifts from passive annoyance to genuine impatience. His growing pressure is not Nen or killing intent, but an overwhelming presence that makes others instinctively want to escape.
• Meruem’s duplicate, Black Saitama, attacks again with the same copied strength and speed. Saitama effortlessly dodges the punch and destroys the duplicate with a single casual strike.
• The punch causes Black Saitama’s body to fracture and shatter into countless pieces, apparently defeating it instantly.
• Meruem reveals that the fight is not over. The black smoke from the destroyed duplicate regenerates and divides, forming two identical Black Saitamas.
• The chapter ends with the two duplicates preparing to attack Saitama simultaneously.

Character Development

• Saitama: Reveals an overwhelming level of durability and power while remaining characteristically casual and detached. His priorities remain mundane—his clothes and sandals—until Meruem’s continued destruction finally provokes real irritation. His effortless destruction of Black Saitama demonstrates that his true power may exceed even the copied version of himself.
• Meruem: Experiences doubt for the first time. His confidence in his analysis and ability to copy Saitama’s strength is shaken when Saitama survives and destroys the duplicate with ease. However, he regains composure by using the duplicate’s regenerative ability to create two new opponents.
• Black Saitama: Initially appears to be an exact replica of Saitama, possessing identical power and speed, but is destroyed almost instantly by the original. Its regeneration and replication ability make it an ongoing threat despite its lack of individuality or emotion.

Significant Themes

• The limits of logic and prediction: Meruem’s calculations fail because Saitama’s abilities exceed normal physical laws and established standards of strength.
• The contrast between the ordinary and the extraordinary: Saitama treats catastrophic destruction as an inconvenience comparable to losing inexpensive clothing, emphasizing his absurd power and mundane personality.
• Escalation and adaptation: Although Saitama defeats the first duplicate effortlessly, Meruem counters by multiplying it, suggesting that the battle will continue through increasingly dangerous forms.
• Confidence versus uncertainty: Meruem’s belief in his superior judgment is challenged, revealing that even he can be forced into doubt when confronted with something he cannot understand.
• Power without spectacle: Saitama’s decisive punch is silent and understated, lacking the shockwaves and visual destruction associated with Meruem’s attacks, yet it proves far more effective.

Character Interactions

• Saitama and Meruem: Their exchange highlights their contrasting perspectives. Saitama complains about practical costs and property damage, while Meruem struggles to comprehend his strange priorities and impossible resilience. Saitama’s irritation signals a shift in their relationship from passive observation to serious confrontation.
• Saitama and Black Saitama: The duplicate mirrors Saitama’s physical abilities and fighting stance but lacks his personality. Saitama defeats it with minimal effort, establishing that copied power alone cannot match the original.
• Meruem and Black Saitama: Meruem treats the duplicate as a controlled weapon and remains confident in its regenerative potential. Its destruction initially appears to undermine him, but its reformation into two copies restores his tactical advantage.

Chapter Summary: “Infinite Proliferation”

Key Plot Points and Events

• Meruem reveals his Dark Continent ability, Infinite Division, acquired by devouring a calamity-bearing species. Any copy that is killed—unless completely annihilated at the atomic level—splits into two identical copies with no loss of strength.
• After Saitama destroys two copies, they become four, then eight, sixteen, and so on. The copies retain Saitama’s speed and power, quickly overwhelming the arena.
• Genos calculates that the number of copies will reach millions within an hour. Gon and Killua realize the battle is a logical trap: the more Saitama attacks, the faster Meruem’s army grows.
• Meruem confidently explains that Saitama cannot win because his stamina is finite while the copies are effectively infinite. The black Saitamas eventually spill out of the ring and into the audience stands.
• Saitama suddenly stops punching. Though his clothes are damaged, he is completely uninjured and shows no fatigue.
• Instead of attacking, Saitama begins walking toward Meruem. Any copy that touches him disintegrates instantly, without requiring a punch or producing any sound. The multiplying army cannot slow him down.
• Meruem becomes increasingly alarmed as his supposedly unbeatable ability proves ineffective. He retreats for the first time, experiencing genuine fear.
• Saitama reaches the edge of the ring, assumes a punching stance, and declares that he is finished playing and is ready to end the fight.

Character Developments

• Saitama: Initially treats the multiplying copies as a minor inconvenience and experiments by increasing his attacks. He then recognizes that destroying them conventionally is pointless. His calm shifts into an emotionless, overwhelming determination as he simply walks through the horde.
• Meruem: Begins the chapter confident that Infinite Division guarantees victory. His certainty collapses when Saitama finds a way around the ability without directly fighting the copies. Meruem’s fear marks a major reversal in their power dynamic.
• Genos: Uses his analytical systems to track the exponential growth and realizes the danger, but refrains from firing his energy cannon because it would only create more copies.
• Gon and Killua: Understand the strategic impossibility of the situation and become visibly frightened, recognizing that each copy is as powerful as Saitama.
• Netero: His experience with powerful Nen users offers no solution; he is deeply disturbed by an ability that appears impossible for humanity to overcome.

Significant Themes

• Infinite escalation: The ability turns strength against itself, making every successful attack worsen the opponent’s position.
• Limits of logic: Meruem’s strategy is mathematically sound, but Saitama’s overwhelming physical absurdity bypasses the rules Meruem assumes govern the battle.
• Confidence versus adaptability: Meruem relies on an apparently unbeatable plan, while Saitama succeeds by abandoning the expected method of fighting.
• Fear of the incomprehensible: Meruem is not merely frightened by Saitama’s strength but by his disregard for the logic of Infinite Division.
• Simplicity overcoming complexity: A complicated, limitless ability is countered not by a stronger technique, but by Saitama calmly walking forward.

Character Interactions

• Meruem repeatedly taunts and explains the inevitability of Saitama’s defeat, presenting the battle as an unsolvable problem.
• Saitama barely responds to Meruem’s speeches, focusing instead on testing the copies and eventually realizing that direct attacks are unnecessary.
• Genos, Gon, Killua, and Netero observe the battle from the sidelines, each recognizing the danger in a different way.
• Meruem’s relationship to Saitama changes from confident superiority to uncertainty and fear as Saitama effortlessly advances through the multiplying army.
• The chapter ends with Saitama directly confronting Meruem, signaling the transition from defensive endurance to the decisive final attack.

Chapter Summary: “Absolute Nothingness”

Key Plot Points and Events

• Meruem senses an instinctive terror emanating from Saitama, recognizing it as something beyond Nen or ordinary power.
• He orders his 1,024 Black Saitama duplicates to attack while preparing his ultimate technique, Black Star, a highly compressed Nen attack capable of destroying Heaven’s Arena.
• Saitama remains focused solely on Meruem and uses his Serious Series: Normal Punch.
• The resulting fist wind completely erases the Black Saitamas one after another without explosions or resistance. The attack continues toward Meruem.
• Meruem is unable to dodge or defend himself. His body, armor, wings, and even the fundamental particles composing him are annihilated.
• Because Saitama’s attack erases even the concept of death, Meruem cannot activate his Infinite Division ability, whose prerequisite is dying.
• Meruem realizes that his calculations, logic, pride, and immense power are meaningless before Saitama’s overwhelming strength.
• After the attack, Heaven’s Arena is silent and largely intact aside from warped railings and cracked flooring. Saitama complains only that his clothes have been damaged again.
• The crowd erupts in celebration, viewing Saitama’s victory as a miracle and the defeat of an impossible Dark Continent disaster.
• Netero, Killua, and Gon each react with awe, though Killua calls Saitama the true monster.
• Saitama ignores the fame and immediately asks Genos to accompany him for ramen.
• The chapter ends with a tiny black fragment briefly transforming into smoke and disappearing, hinting that Meruem or some remnant of his power may have survived.

Character Developments

• Saitama: Demonstrates absolute, effortless superiority. His calmness contrasts sharply with the scale of the battle, and he remains more concerned with his ruined clothes and hunger than with his victory or public adoration.
• Meruem: Experiences genuine fear for the first time. His confidence and belief in logic, proliferation, and overwhelming force collapse as he recognizes that Saitama exists beyond the systems he understands. He dies unable to resist or even meaningfully react.

Significant Themes

• The absurdity of power: The destruction of a seemingly world-ending threat is treated by Saitama as an inconvenience delaying his meal.
• Possible survival and continuation: The final black fragment introduces suspense, suggesting that Meruem’s influence, consciousness, or power may not be completely gone.
