• Tanjiro invites both of them to join the mission. They accept, forming a traveling squad with him and Sanemi.

• Zenitsu panics at the possibility of dying young from awakening the mark, but immediately becomes eager again when Tanjiro assures him that Asuramaru can heal the bodily damage.
• After two days of travel, the group arrives in the brightly lit, crowded Yoshiwara Entertainment District.

Chapter Summary: “Split Up” / “Who Would Serve as the Bait”

Key Plot Points and Events

• Akamaru detects a demon hidden beneath the Kabukicho district. The demon seems to possess an ability resembling Upper Rank Four Hantengu’s cloning technique, and numerous human presences are mixed with its aura.
• Tanjiro and the others arrive at Ogimoto House, where Tanjiro proposes splitting up to avoid alerting the demon:
  • Sanemi and Inosuke will enter Ogimoto House and search for a hidden underground entrance.
  • Tanjiro and Zenitsu will search for the demon’s main body.
• Sanemi initially doubts his ability to locate a concealed entrance, but Inosuke confidently volunteers, boasting about his experience finding holes and hidden spaces in the mountains.
• Zenitsu tries to join Sanemi and Inosuke, but Sanemi knocks him on the head and forces him to accompany Tanjiro instead.
• Akamaru leads Tanjiro and Zenitsu to Kyogoku House, where the demon’s scent is especially strong. Akamaru determines that the building is likely the demon’s lair, but the demon itself is not currently there.
• Tanjiro decides not to attack immediately and instead returns toward Ogimoto House, presumably to regroup with Sanemi and Inosuke.
• The scene then shifts to the Infinity Castle, where the Upper Ranks gather at Muzan’s command. Akaza, Douma, Gyutaro, Daki, and the demon occupying the strange pot are present, while Michikatsu observes from the shadows.
• Douma casually greets Akaza, provoking him. Akaza punches and destroys Douma’s head, but Douma regenerates instantly and continues smiling.
• Muzan arrives and announces that Hantengu has been killed, leaving a vacancy among the Upper Ranks. He criticizes the demons for failing to defeat the powerful demon slayer.
• Muzan punishes Akaza for losing to the demon slayer and fleeing. The revelation shocks the other Upper Ranks, especially Michikatsu.
• Douma volunteers to personally kill Tanjiro, confidently claiming that he has never disappointed Muzan.

Character Developments

• Tanjiro demonstrates strategic thinking and compassion. Although he wants to save the trapped humans immediately, he understands that attacking carelessly could cause the demon to escape and endanger more people.
• Sanemi shows practical leadership despite his harsh behavior. He accepts Tanjiro’s plan, takes responsibility for searching Ogimoto House, and trusts Inosuke’s specialized abilities.
• Inosuke displays confidence in his instincts and survival skills. His unusual mountain experience makes him the most suitable person to locate hidden entrances.
• Zenitsu remains fearful and reluctant, trying to avoid the dangerous investigation. His complaints also provide comic relief, especially after Sanemi strikes him for resisting the plan.
• Akamaru continues acting as an invaluable guide by tracking the demon’s aura and identifying locations connected to it. He also mocks Zenitsu, showing a teasing but observant personality.
• Akaza is portrayed as enraged and humiliated after his defeat by the demon slayer. His hatred of Douma remains intense, but he restrains himself after attacking him.
• Douma remains cheerful, provocative, and unnervingly calm even after being decapitated. His confidence suggests that he is eager to confront Tanjiro.
• Muzan reveals his frustration with the Upper Ranks and becomes more openly threatening. His punishment of Akaza reinforces his absolute authority.
• Michikatsu becomes increasingly suspicious that the demon slayer may be connected to Yoriichi, suggesting that Tanjiro’s power has attracted Upper Rank attention.

Significant Themes

• Strategy versus impulsiveness: Tanjiro avoids a reckless attack and divides the group to investigate multiple possibilities.
• Compassion and responsibility: The heroes must balance rescuing humans immediately with preventing the demon from escaping.
• Trust in individual strengths: Each member is assigned a role suited to their abilities—Inosuke’s tracking instincts, Sanemi’s combat strength, and Tanjiro’s scent detection and judgment.
• Hierarchy and fear within the demons: Muzan’s authority is absolute, and even powerful Upper Ranks are punished for failure.
• Rivalry and hostility: Akaza’s hatred of Douma contrasts sharply with Douma’s playful attitude, making their interaction both humorous and threatening.
• Growing danger surrounding Tanjiro: The Upper Ranks now recognize Tanjiro as a serious threat, increasing the stakes of the investigation.

Character Interactions

• Tanjiro consults Sanemi and proposes the split, establishing him as a tactical coordinator.
• Sanemi and Inosuke form the underground-search team, with Inosuke’s confidence compensating for Sanemi’s lack of investigative skill.

Chapter Summary

Key Plot Points and Events

• Muzan Kibutsuji orders all Upper Rank demons to unite and eliminate the powerful Demon Slayer. He promotes Nakime to Upper Rank Four so she can gather intelligence and commands the remaining Upper Ranks to stay ready for battle.
• Muzan rejects Gyokko’s unverified intelligence, declaring that every Upper Rank will participate if the information proves true. He considers hiding in the Infinity Castle indefinitely if they fail.
• Tanjiro and the others regroup at Ogimoto House. Tanjiro confirms that the demon’s main lair is beneath Kyogoku House, though the demon itself is absent.
• Azhuromaru identifies the hidden entrance beneath the floorboards of Ogimoto House and warns that the enemy is likely an Upper Rank demon.
• Because fighting in the crowded entertainment district could cause many civilian deaths, Sanemi proposes drawing the demon away with bait. Zenitsu is selected because his rare blood should attract the demon, while Sanemi plans to kill its underground clone.
• The following night, Tanjiro learns that the demon has returned. The group breaks through the floor and discovers that the passage is too narrow for most of them.
• Inosuke volunteers to dislocate his body and enter the passage. Azhuromaru confirms that the underground clone is relatively weak, so Inosuke is assigned to fight it after waiting thirty minutes.
• Tanjiro and Zenitsu go to Kyogoku House to lure out the main demon. Zenitsu uses his rare blood as bait, but the demon refuses to eat him because she finds him too ugly and loses her appetite.
• Zenitsu returns embarrassed and frustrated. Tanjiro comforts him, then begins searching for another strategy.

Character Developments

• Muzan becomes more aggressive and desperate, willing to risk all the Upper Ranks in a decisive attack rather than continue reacting defensively.

• Protection of civilians: Tanjiro’s concern about fighting in a crowded district emphasizes the moral responsibility of the Demon Slayers.
• Trust and teamwork: The plan depends on each member fulfilling a separate role—Sanemi fighting the clone, Inosuke entering the passage, and Tanjiro and Zenitsu luring the main demon.
• Desperation and escalation: Muzan’s decision to mobilize every Upper Rank shows the growing seriousness of the conflict.
• Appearance and humiliation: Zenitsu’s failure is played comedically, but it also highlights how appearances and personal pride affect the bait strategy.
