  • A

Platinum Ability Upgrade Card

• The bizarre Demon Power AK-47, a weapon that converts Demon Power into bullets while preserving the energy’s characteristics.

Chapter Summary

Tanjiro, Inosuke, and Zenitsu arrive at Mount Natagumo, suspected to be a trap connected to Muzan Kibutsuji. Zenitsu remains terrified but agrees to follow Tanjiro, while Inosuke eagerly takes the lead. Zenitsu also continues his inappropriate “true love” fixation on Azuromaru, much to everyone’s disgust—and to Lin Fan’s private amusement.
At the mountain’s entrance, the group finds an injured Demon Slayer being controlled by nearly invisible threads. Lin Fan detects the trap, allowing Tanjiro to cut the threads and rescue him. The survivor explains that his squad was forced to attack one another after entering the mountain and warns that ordinary Demon Slayers will not survive inside. Despite this, Tanjiro insists on continuing because they were sent to provide support.
Inside the forest, Lin Fan uses his enhanced senses to detect demons and guide Tanjiro. The group encounters more Demon Slayers whose bodies are being manipulated by threads. Rather than fight the controlled victims, Tanjiro follows Lin Fan’s advice and targets the demon controlling them. He cuts through the threads restraining several Demon Slayers, including a girl who begs him to leave before being forced to attack him.
As Tanjiro advances, he discovers increasingly horrific examples of the demon’s cruelty, including mutilated and modified corpses. Enraged by the demon’s abuse of human lives, Tanjiro unleashes Water Breathing and destroys the controlled bodies and their threads. He eventually confronts the female demon responsible. Though initially terrified and prepared to fight, she realizes she cannot escape and willingly accepts death, hoping to be freed from the suffering she has endured.
Recognizing her resignation and tragic condition, Tanjiro does not kill her violently. Instead, he uses Water Breathing, Fifth Form: Blessed Rain After the Drought, a gentle technique intended to grant a painless death. His compassion deeply moves the demon in her final moments, and Tanjiro looks upon her without hatred or malice.

Character Developments

• Tanjiro becomes increasingly decisive and powerful, quickly rescuing victims and confronting the controlling demon. His anger toward the mistreatment of human lives reveals a stronger emotional intensity, but he remains compassionate even toward demons.

• Lin Fan/Azuromaru acts as Tanjiro’s unseen guide, detecting demons, identifying traps, and directing the group toward the real threat. He also takes mischievous pleasure in Zenitsu’s romantic misunderstanding.
• The female demon shifts from panic and fear to resignation. Her willingness to die suggests that she has been suffering under circumstances she can no longer endure.

Major Themes

• Compassion amid violence: Tanjiro’s final attack shows that killing a demon can still be an act of mercy.
• Loss of free will: The spider threads symbolize the horrifying destruction of personal agency, forcing Demon Slayers to harm one another.
• Righteous anger: Tanjiro’s fury is motivated not by hatred of demons alone, but by outrage at the cruelty inflicted on helpless people.
• Fear and courage: Zenitsu’s terror contrasts with his decision to keep moving, showing that courage can exist despite fear.
• Freedom through death: For the female demon, death represents release from manipulation, pain, and psychological torment.

• The spider-headed demon engages Inosuke, while the spider demon with a human head pursues the terrified Zenitsu.
• Tanjiro continues fighting Rui and the female spider demon. With Lin Fan’s warning that more Lower Rank demons are approaching, Tanjiro quickly decapitates the female demon using Water Breathing, Third Form: Flowing Dance.
• Rui takes advantage of the opening to wound Tanjiro with his threads, but Lin Fan immediately heals him through Demon Power.
• Three additional Lower Rank demons arrive and surround Tanjiro:
  • Mukago, Lower Rank Four, who controls enormous vines and explosive flower fruits.
  • Rokuro, Lower Rank Two, who observes the battle before attacking.
  • Wakuraba, Lower Rank Three, who hides in the shadows and uses wooden restraints and poisoned shuriken.
• Tanjiro attempts to fight all four demons with Water Breathing, cutting through Rui’s threads and Mukago’s vines. However, the demons coordinate their attacks, trapping him with webs, vines, wooden shackles, and poisonous projectiles.
• After nearly being killed, Tanjiro calls upon Lin Fan—whom he refers to as Arjuro Maru—to lend him power.
• Lin Fan activates Tanjiro’s Demonification, which now lasts four minutes due to Kamanue’s earlier contribution to Tanjiro’s strength.
• The transformed Tanjiro becomes dramatically faster and more dangerous. He dodges Mukago’s explosive fruit bullets and cuts apart Rui’s webs with ease.
• The demons combine their Blood Demon Arts in an attempt to overwhelm him. Tanjiro is ultimately buried beneath the barrage, and the demons assume he has been killed.
• Wakuraba alone senses that something is wrong, relying on his former ninja instincts. The chapter ends as Tanjiro experiences a flashback immediately before the attacks strike.

2. Character Developments

• Tanjiro shows courage and determination by refusing to flee despite being surrounded by several powerful demons. He recognizes, however, that his normal strength is insufficient and willingly accepts Lin Fan’s power.
• His Demonification has become stronger and more sustainable, lasting four minutes instead of only a brief period. The transformation gives him increased speed, power, and confidence.
• Lin Fan continues acting as Tanjiro’s hidden support and protector. He heals Tanjiro repeatedly, detects concealed enemies, and carefully manages the risk of the Demonification ability.

• Mukago appears playful and competitive, treating the battle almost like a game while competing with Rui for credit.

• Wakuraba is more cautious than the others. His instincts warn him that Tanjiro may have survived the combined attack.
• Kamanue, though not directly present, is credited with helping Tanjiro increase the duration and strength of his Demonification.

3. Significant Themes

• Power versus dependence: Tanjiro’s bravery is not enough to defeat the Lower Ranks alone, forcing him to rely on Lin Fan’s supernatural assistance.
• Transformation and identity: Demonification grants Tanjiro immense power, but it also changes his appearance, aura, and behavior, raising questions about how much of his humanity remains.
• Teamwork and coordinated combat: The demons nearly defeat Tanjiro by combining different abilities—threads, vines, poison, restraints, and projectiles—rather than relying on individual strength.
• Confidence and deception: The demons assume Tanjiro is dead, while the narrative emphasizes that appearances can be misleading. Wakuraba’s instincts suggest the fight is not over.

• Mukago challenges Rui’s claim over Tanjiro, creating competition between the demons even while they attack him together.
• Rokuro questions Rui’s failure to kill Tanjiro, while remaining detached from the immediate struggle.
• Wakuraba’s instinctive suspicion contrasts with the confidence of the other demons, establishing him as the first to doubt their apparent victory.
• Tanjiro’s appeal to Lin Fan marks a moment of trust and dependence, leading directly to his second, more powerful Demonified state.

Chapter 32 Summary

Key Plot Points and Events

• On another battlefield, Rui’s death causes the spider demons’ borrowed power to disappear. Their bodies shrink and weaken dramatically.
• Inosuke takes advantage of the weakened burly spider demon and chases it down, killing it.

• The difference between appearance and identity: Although Lin Fan uses Tanjiro’s body without visibly changing it, his aura, eyes, and behavior make it clear that an entirely different combatant has emerged.
• Power gained through emotion and death: Rui’s death produces negative emotional energy and Demon Power, turning the defeat of one enemy into a source of strength for Lin Fan and Tanjiro.

• Her treatment miraculously restores Kagaya’s disfigured face and even returns his sight. The Hashira initially celebrate, believing their master has been fully cured.

• Acceptance of mortality: Kagaya’s calm response emphasizes his willingness to accept death while valuing the additional time he has been given.
• Trust and loyalty: Tanjiro’s faith in Ashuramaru contrasts with Sanemi’s suspicion, while the Hashira’s reactions reveal their profound devotion to Kagaya.

Chapter 37 Summary

Key Plot Points and Events

• Lin Fan, speaking through Asuramaru, reveals that the curse afflicting the Ubuyashiki family originates from Muzan Kibutsuji. Killing Muzan would remove the curse.
• Kagaya Ubuyashiki declares that killing Muzan has always been his goal and believes the combined strength of the Hashira, Tanjiro, and Asuramaru may finally accomplish it.
• The Insect Hashira asks whether Asuramaru can continue healing Kagaya if the curse resurfaces. Lin Fan claims he can repeatedly suppress the illness, though doing so will require increasing amounts of power.
• Kagaya offers Lin Fan access to all Demon Slayer Corps intelligence and missions involving demons, allowing him to regain strength by killing them. In exchange, he asks about Asuramaru’s abilities and knowledge of Muzan.
• Lin Fan explains Asuramaru’s powers:
  • Blood Cry: wounds inflicted by the blade cannot heal properly and cause endless bleeding.
  • Healing: can completely restore severely injured people as long as they are still alive.
  • Nourishment: killing demons allows Asuramaru to gain Demon Power and strengthen its wielder.
  • Demonification: allows the wielder to use Asuramaru’s powers directly, though prolonged use may turn them into a demon.
• The Hashira are stunned by the blade’s potential, realizing it could eliminate demons’ regenerative advantage and dramatically strengthen human fighters.
• Lin Fan describes Muzan as cowardly but extremely powerful, explaining that Muzan possesses multiple Blood Demon Arts, including spinal whips and mouths covering his body.
• He bluntly tells the Hashira that they are currently too weak to face Muzan.
• Lin Fan reveals that Breathing Styles have three levels: ordinary mastery, the Demon Slayer Mark, and the Transparent World. None of the Hashira have awakened the latter two.
• He warns that the Demon Slayer Mark greatly increases power but causes its users to die before age twenty-five.
• When asked about Yoriichi Tsugikuni, Lin Fan explains that Yoriichi created Sun Breathing, possessed both the Mark and the Transparent World, and was likely the strongest human ever.
• Yoriichi discovered Muzan had five brains and seven hearts, making decapitation ineffective. Only Sun Breathing and sunlight can kill Muzan permanently.
• Despite Muzan’s overwhelming abilities, Yoriichi defeated him almost instantly, and Muzan survived only by fleeing.

Character Developments and Interactions

• Kagaya Ubuyashiki remains determined and pragmatic. He accepts the risks of relying on Lin Fan and establishes a mutually beneficial agreement to support Asuramaru’s recovery.
• Lin Fan/Asuramaru presents himself as indispensable while concealing the full truth of his abilities and the limits of his supposed healing powers. He deliberately exaggerates or withholds information when useful.
• Tanjiro is confirmed as Asuramaru’s chosen wielder and an example of the blade’s strengthening effect, having already defeated four Lower Ranks.
• The Hashira shift from suspicion and grief to cautious hope after learning about Asuramaru’s healing and enhancement abilities. They are also humbled and irritated when Lin Fan calls them weak.
• Nezuko remains controversial. Kagaya formally states that he accepts Tanjiro and Nezuko, though the Hashira still struggle to accept a demon within the Corps.
• Kagaya and Lin Fan develop a transactional but respectful relationship, with Kagaya recognizing Lin Fan’s value while Lin Fan uses Kagaya’s desperation to secure access to demon missions.

Significant Themes

• Hope against an inherited curse: The Ubuyashiki family’s centuries-long suffering gives the fight against Muzan personal meaning.
• Power and sacrifice: The Demon Slayer Mark offers immense strength at the cost of a shortened life, highlighting the price of victory.
• Trust and manipulation: Kagaya must rely on Asuramaru despite incomplete information, while Lin Fan carefully controls what he reveals.
• Humanity versus monstrosity: Asuramaru grants humans demonic abilities while claiming its demons differ from Muzan’s, blurring the boundary between human and demon.
• Legacy and forgotten knowledge: Yoriichi’s techniques and abilities were lost because marked swordsmen died young, emphasizing the importance of preserving knowledge.
• Hope through cooperation: The Corps, Tanjiro, Nezuko, and Asuramaru begin moving toward a unified effort against Muzan, despite lingering distrust.

Chapter Summary

Key Plot Points and Events

• Lin Fan reveals that Yoriichi Tsugikuni once defeated Muzan almost instantly, cutting down 1,500 of the demon’s 1,800 escaping pieces. Muzan survived only by fleeing.
• He explains that Muzan later killed those who knew Sun Breathing to prevent another swordsman like Yoriichi from appearing.
• Since Tanjiro has inherited the Dance of the Fire God, the Demon Slayer Corps realizes he may be the second person capable of using Sun Breathing—and potentially someone who could surpass Yoriichi with Asuramaru’s power.
• The Hashira recognize that Tanjiro’s survival is essential because he is both a Sun Breathing user and Asuramaru’s wielder.
• Asuramaru ends the meeting and returns to Tanjiro’s blade in the form of black mist. Before disappearing, he corrects Kagaya’s assumption that he is female, revealing that he is male.
• Attention then shifts to Nezuko. Although the Hashira acknowledge Tanjiro’s importance, many still fear that Nezuko may eventually eat humans.
• Sanemi proposes imprisoning Nezuko rather than executing her. Tanjiro vows that he will kill Nezuko and himself if she ever harms someone.
• Kagaya takes a cautious but sympathetic position, pointing out that Nezuko has not eaten anyone since becoming a demon.
• To test Nezuko’s restraint, Sanemi cuts his own arm and exposes her to his exceptionally tempting “Rare Blood.” Nezuko struggles intensely against her hunger as Kagaya watches anxiously.

Character Developments

• Tanjiro: Becomes central to the Corps’ hopes of defeating Muzan. He remains humble and embarrassed by the Hashira’s attention but firmly defends Nezuko and promises to take responsibility for her actions.

• Kagaya Ubuyashiki: Recognizes Tanjiro’s strategic importance and quietly commits to protecting him and Nezuko. He balances the Corps’ fears with evidence of Nezuko’s peaceful behavior.
• Sanemi Shinazugawa: Though hostile toward Nezuko, he acts from principle and concern for the Corps rather than simple malice. He accepts that Tanjiro cannot be sacrificed and devises a direct test of Nezuko’s control.
• Other Hashira: Rengoku, Gyomei, and Tengen are impressed by Tanjiro’s potential. Mitsuri becomes especially charmed by Asuramaru and Tanjiro’s awkwardness. Obanai remains suspicious but is also interested in Asuramaru’s powers.

Significant Themes

• Hope against Muzan: Tanjiro’s mastery of Sun Breathing represents the possibility that the Corps can finally overcome Muzan.
• Power and responsibility: Tanjiro’s importance makes his safety a priority, but it also places enormous responsibility on him as Nezuko’s protector and as a potential successor to Yoriichi.
• Trust versus prejudice: The Hashira must decide whether to trust Tanjiro and Nezuko despite their unusual circumstances and the Corps’ painful history with demons.
• Resisting one’s nature: Nezuko’s struggle against the smell of Rare Blood tests whether a demon can overcome its instinct to consume humans.
• Sacrifice and survival: Tanjiro’s willingness to die for Nezuko contrasts with the Corps’ insistence that he must survive to defeat Muzan.

Character Interactions

• Kagaya Ubuyashiki accepts this as proof that Nezuko will not attack humans. He cancels the need for her imprisonment but warns Tanjiro that he must continue proving her safety to those who distrust demons.

• Lin Fan spends 20,000 Emotion Points to unlock Demon Curse and Borrowed Power, preparing for the anticipated confrontation with Upper Rank Three, Akaza.
• Kagaya promotes Tanjiro from the lowest rank, Mizunoto, to the highest standard Corps rank, Kinoe—referred to in the chapter as an A-rank promotion. Tanjiro is not made a Hashira because he still lacks maturity and did not defeat a Twelve Kizuki entirely through his own power.

Chapter Summary

Key Plot Points and Events

• The Hashira agree to train Tanjiro in rotation, with each one taking responsibility for a day. Zenitsu and Inosuke are included as unintended participants.
• That evening, Tanjiro reflects on his dependence on Akaza, Urokodaki, Tomioka, and the Master. He acknowledges his weakness and resolves to master the Dance of the Fire God, become stronger, and eventually turn Nezuko back into a human.
• The next morning, Sanemi Shinazugawa arrives to conduct the day’s training. He forces Tanjiro, Zenitsu, and Inosuke to follow him to an isolated plain.
• Sanemi reveals that their training will consist of fighting him directly, warning that serious injuries are likely.
• Tanjiro counters Sanemi’s Wind Breathing with Water Breathing, managing to divert Sanemi’s tornado attack. Sanemi is impressed by Tanjiro’s strength, though the redirected attack nearly strikes Zenitsu.
• Sanemi stops the attack at Zenitsu’s neck, then punches him unconscious for panicking and complaining.
• Inosuke eagerly challenges Sanemi. Although he uses his inventive Beast Breathing techniques, Sanemi easily defeats him with a single Wind Breathing form and a kick.
• Sanemi declares Inosuke “dead” for the purposes of the fight, but Inosuke stubbornly insists that he is still alive and refuses to yield.

Character Developments

• Nezuko: Remains dependent on Tanjiro and Akaza for protection. Her peaceful sleep contrasts with Tanjiro’s serious reflections about her future.
• Akaza: Continues to criticize Tanjiro harshly while encouraging him to improve. His presence inside the sword suggests an unusual bond with Tanjiro and Nezuko, despite his denial of emotional attachment.
