• Enmu tried to put Giyu to sleep again, but Giyu's Eleventh Form, Dead Calm, stopped the attack.
• Giyu moved to cut off Enmu's head, but a biwa sounded and Enmu disappeared.

Muzan punished Enmu for the deaths of Rokuro and Rui, then gave him more of his blood after Enmu welcomed the prospect of being killed by him. At the Hashira Meeting, Giyu reported that Enmu had vanished, while the Hashira examined Nezuko and Sanemi remained convinced that a demon could not be trusted.

• Muzan told Enmu that Rokuro and Rui were dead and that Enmu had nearly been killed by Giyu.

• Kanae, Mitsuri, and Shinobu examined Nezuko and discussed her ability to survive without eating humans.
• Sanemi doubted that Nezuko could truly be harmless, suspecting that other Hashira shared his distrust.

• Kagaya let Haruto sleep and said he understood why Haruto trusted a demon, adding that a demon was connected to his illness.

• Kagaya told the Hashira that the potion Tamayo developed treated his illness and gave Haruto slow regeneration after multiple injections.
• Tengen, Sanemi, Gyomei, Rengoku, and Shinobu expressed interest in receiving the potion, while Haruto woke and learned what they were discussing.

• Haruto noticed a beautiful, green-eyed patient calling him “Sunny Doll” and realized the patient was Inosuke.

Haruto comforted Shinobu after she revealed she had nearly sacrificed herself by replacing her blood with wisteria poison to kill an Upper Rank. The next day, Genya delivered a stronger replacement for Haruto’s mechanical training puppet, which Haruto still thought deserved a different name.

• Haruto pushed Shinobu on a swing as she told him she had once considered poisoning her body and letting a demon eat her to defeat an Upper Rank.

• Genya said the puppet was far stronger than the old one, and Haruto wondered whether it could be given a different name.

Kanao and Inosuke fought the Mechanical Puppet while Tanjiro and Zenitsu watched, and Haruto received drugs from Tamayo. He gave Muichiro the Dream Thief Drug to help him recover his memories, then shared a tender moment with Shinobu.

• Kanao dodged the Mechanical Puppet's attacks and kicked it toward Inosuke, who challenged it with his bare fists and got repeatedly struck.
• Haruto received twelve doses of Demonization Potion, syringes, and three doses of Tamayo's Dream Thief Drug at Demon Slayer Corps Headquarters.
• Haruto found Muichiro behind Gyomei and offered him the Dream Thief Drug to stimulate his lost memories.
• Haruto taught Muichiro how to construct an anchor, then left him asleep in a quiet room at the Butterfly Mansion.
• Haruto explained the drug's ingredients to Shinobu, who declined to use it and wished for everyone to stay safe and healthy.

Muichiro dreamed of his childhood with his twin brother Yuichiro and their clashes over Amane’s offer to join the Demon Slayer Corps. He woke after seven days in the potion-induced dream, but admitted he had forgotten the anchor that was supposed to keep him grounded.

• Haruto asked why Muichiro had not used his anchor, and Muichiro said he had forgotten what he had chosen.

Haruto responded to an urgent demon report in Hirano and found Saori, the woman he had helped years earlier, transformed into a demon calling herself Fisherwoman.

• Haruto recognized the woman as Saori and found a worker's smoking pipe beneath the seawater at his feet.
• Saori called herself Fisherwoman, said she was waiting for her husband, and asked Haruto where he was.

• Haruto confronted the Fisherwoman and learned she still believed her husband would return, unaware that he was dead.
• The Fisherwoman attacked Haruto with her Blood Demon Art, Fish Bubble Cloud, but Haruto resisted the poison and cut off her head.

• A small, dark face appeared through the Fisherwoman’s stretched belly and grinned at Haruto.
• Haruto panicked and unleashed a flurry of slashes while shouting that he had seen a ghost.

After hearing about the abuse she and her mother suffered, Haruto acknowledged that their tormentors had been wrong but refused to excuse their killings, and Demon Princess attacked him.

• Haruto unleashed over a hundred slashes, minced Saori’s body, and pushed past the limits of his swordsmanship.

• Demon Princess explained that Doma, a demon with rainbow-colored eyes, had turned them both into demons.
• Haruto said the villagers had wronged them but refused to apologize for their deaths or let Demon Princess live.
• Demon Princess dropped her helpless act, showed her fangs, and lunged at Haruto.

Haruto defeated the Demon Princess and learned that the Fisherwoman was Saori, who died remembering her human life. Back at the Butterfly Mansion, he learned that Tanjiro, Inosuke, and Zenitsu had gone to the Mugen Train to meet Kyojuro, then rushed after them when a comment warned him to help.

• Haruto severed the Demon Princess’s hand, dodged her Blood Demon Art, and killed her with his sword.
• The Fisherwoman recognized Haruto as Mr. Haruto and asked whether a demon had killed her husband, Yūki, before she died.
• Haruto returned to the Butterfly Mansion and found Kanao alone in the courtyard.
• Kanao told Haruto that Tanjiro, Inosuke, and Zenitsu had left for the Mugen Train to meet the Flame Hashira.
• After a scrolling comment urged him to help Kyojuro, Haruto ran toward the train.

Haruto reached the station where the Mugen Train incidents had occurred and learned that Kyojuro had recently bought all the bento there. As Haruto stopped to eat, a fleeing demon raced toward the station, and Haruto caught it by the head.

• Haruto arrived at the station before dawn after traveling through the night and recalled the disappearances aboard the Mugen Train.
• Haruto bought ten beef hot pot bento boxes from an elderly woman and her granddaughter, who told him that a red-and-yellow-haired swordsman had bought all their bento hours earlier.
• Haruto realized the swordsman was probably Kyojuro and learned that he had warned the women a demon might be nearby.
• Haruto sensed a demon rushing toward the station and caught it by the head before it could enter.

Haruto and Kyojuro defeated a foul demon outside the station, and Kyojuro spoke with a grandmother who had known his father, Shinjuro. The two shared breakfast before Kyojuro loudly announced that he had eaten five bentos.

• Haruto held the foul demon while Kyojuro explained it had attacked an injured woman and was probably unrelated to the Mugen Train incident.
• The foul demon tore its own skull apart and rushed toward the station, hoping to take Afu hostage, but Kyojuro beheaded it as she opened the door.

• Kyojuro told Haruto that the elderly woman had met Shinjuro and had compared Kyojuro to his father, which made him happy.
• Haruto gave Kyojuro three bentos, and Kyojuro ate them before shouting, "Five ants!"

Haruto and Kyojuro boarded the Mugen Train to hunt the demon responsible for its deaths, while three new recruits also sneaked aboard. Haruto sensed a demon on the moving train and prepared to face the suspected Upper Rank Three, Akaza.

• Haruto and Kyojuro decided to wait for the Mugen Train demon, and Haruto said he would stay out of the fight if it was only a Lower Rank so the current members could gain experience.
• When the train resumed service despite the unresolved deaths, Haruto condemned the authorities and challenged Kyojuro to race to its next station.
• Kyojuro stopped to help Xiao Fu and her grandmother with their bento boxes while Haruto ran ahead.
• Tanjiro and two other boys arrived at the station, and the boar-headed boy attacked the train before the patrol chased them away.
• Haruto waited on the train roof as the scrolling comments hinted at a new season, then the three boys sneaked aboard after dark.
• As the train set off, Haruto sensed a demon aboard and prepared to conceal the presence of two Hashira while gambling that he could kill Akaza.

Haruto fought Upper Rank Three Akaza after Akaza arrived at the Mugen Train, while Tanjiro, Inosuke, Kyojuro, and Zenitsu battled Enmu and protected the passengers. Akaza healed from Haruto’s strike and tried to recruit him as a demon, then attacked again.

• Haruto watched Enmu explain his dream-entering ropes while Kyojuro and the boys slept, and Tanjiro’s shout signaled that they had awakened.
• Enmu merged with the Mugen Train, prompting Tanjiro and Inosuke to attack outside while Kyojuro and Zenitsu defended the passengers inside.
• A pale-faced boy ordered Akaza to deal with the Demon Slayers, and Haruto sensed the Upper Rank demon approaching.
• Haruto launched a surprise attack on Akaza, who countered with Destructive Death: Annihilation Style and quickly regenerated his injured hand.
• Akaza praised Haruto’s swordsmanship and invited him to become a demon, but Haruto mentioned Doma’s earlier attempt.
• Akaza struck at Haruto again with a scorching punch.
