• A Kakushi carried Gyomei Himejima and his weapons to the Swordsmith Village, where Gyomei thanked him and mistook the gathered Hashira for a welcoming party.

• Upper Rank Five Gyokko emerged from a porcelain pot in the forest and muttered about destroying the Swordsmith Village and using its residents as materials for his art.
• Gyokko withdrew into his pot and headed for the village dining hall, expecting few people to remain there.

The Hashira shared a lively meal as Tengen Uzui advised Mitsuri Kanroji and revealed he had three wives. A porcelain pot then rolled into the cafeteria, and Gyokko emerged as all nine Hashira drew their weapons.

Lin Yoriichi killed Upper Rank Five Gyokko at the Swordsmith Village and sent a blood sample to Miss Tamayo for study. After finding a strand of Yushiro’s hair on Chachamaru’s backpack, Lin wondered whether his efforts to locate the Infinity Castle had made the demon lose his hair.

• Lin wrote a reply to Miss Tamayo while Kotetsu played with Chachamaru, then they sent the cat on its way.

In the Infinity Castle, Muzan Kibutsuji raged over Gyokko’s death and turned his anger on Nakime, who had discovered a strange object but had not dared report it.

• Kagaya Ubuyashiki received word that Upper Rank Five had attacked the Swordsmith Village, where all nine Hashira and the villagers remained unharmed.

Rui was summoned to the Infinity Castle and promoted from Lower Rank Five to Upper Rank Six after an Upper Rank died. Muzan ordered him to keep Rokuro and Koyuki on Mount Natagumo, and Rui decided to make them part of his family.

• Sanemi Shinazugawa and Giyu Tomioka attacked Rui, severing both his hands and inflicting wounds that healed only slowly.

• Rui called for his lord's help and tried to escape to the Infinity Castle, but Yoriichi overtook him and blocked his path.

After learning that Yoriichi Tsugikuni and all the Hashira had attacked Mount Natagumo and killed Rui, Koyuki, and Rokuro, Muzan Kibutsuji promoted Nakime to Upper Rank Six. He then announced that an Upper Rank had died, prompting the other Upper Ranks to suspect Doma.

After the battle on Mount Natagumo, Lin Yoriichi learned why Rui had become an Upper Rank and found that killing demons raised his Restoration Rate less than before. He planned to travel to Tokyo to meet Miss Tamayo and pursue new training techniques, leaving Yushiro’s worsening baldness as a curiosity he hoped to investigate.

• Lin Yoriichi saw Gyomei Himejima, Kyojuro Rengoku, and Tengen Uzui kill Koyuki, then summoned Chachamaru to collect her blood.

Lin Yoriichi learned that the Demon Slayer Mark drained a swordsman’s life and received Miss Tamayo’s experimental medicine to reduce its effects. After asking whether she could preserve demon remains, he encountered Hantengu’s Fear form, which tried to escape by splitting into clones.

• Miss Tamayo examined Lin Yoriichi’s Demon Slayer Mark and explained that it raised his temperature and heart rate by drawing on his life reserves.
• Miss Tamayo gave Lin Yoriichi experimental medicine that could partly replenish the life depleted by the mark, while explaining that fully removing its effects would require blood from Muzan Kibutsuji.
• Lin Yoriichi asked whether Miss Tamayo could preserve demon corpses, and she said even fragmented remains would help her research.
• Hantengu’s Fear form searched for the Blue Spider Lily and sensed a space behind a wall in an alley.
• Lin Yoriichi appeared before Hantengu’s Fear form, which pulled off its head and threw it away to create a clone and flee in separate directions.

Lin Yoriichi killed Upper Rank Four Hantengu by slicing his body and hidden true form into tiny fragments. He told Yushiro that Hantengu was now scattered across the ground, while considering whether he needed to wait until his restoration rate reached 100% before fighting Muzan Kibutsuji.

• Hantengu removed his head and began splitting into separate bodies, planning to hide his true form and escape.
• Lin Yoriichi covered Hantengu’s head and body with a vast net of blade strikes, cutting them and Hantengu’s tiny true form into fragments.
• Lin Yoriichi’s restoration rate rose to 76%, and he considered fighting Muzan Kibutsuji before reaching 100% because he had trustworthy companions and strong support.
• Yushiro emerged from the wall, saw the fragments, and asked where the Upper Rank demon was.
• Lin Yoriichi pointed at the scattered fragments and told Yushiro that Hantengu was all over the ground.

Lin Yoriichi killed Upper Rank Four Hantengu and gave Tamayo his remains for experiments before returning with her Demon Slayer Mark relief medicine. At the Butterfly Mansion, Shinobu Kocho reconsidered her plan to sacrifice herself for revenge, while Giyu Tomioka brought her pickled ginger; Tengen Uzui then invited Lin Yoriichi and Giyu to the Entertainment District.

• Lin Yoriichi told Yushiro that he had killed Hantengu, and Yushiro and Tamayo began collecting the demon's fragments for experiments.
• Tamayo warned that Hantengu might have discovered her secrets and said she and Yushiro might need to relocate; she gave Lin Yoriichi the Demon Slayer Mark relief medicine.
• Shinobu Kocho examined the marks from her wisteria poison injections and wondered whether Lin Yoriichi's strength meant she still needed to avenge her sister by dying alongside her enemy.
• Giyu Tomioka arrived at the Butterfly Mansion with pickled ginger for Shinobu, following Gyomei Himejima's advice.
• Tengen Uzui invited Lin Yoriichi and Giyu Tomioka to come with him to the Entertainment District.

Lin Yoriichi, Tengen Uzui, and Giyu Tomioka investigated the Entertainment District after hearing that an oiran had ordered men to collect blue flowers. They arrived at the Kyogoku House just as Muzan Kibutsuji possessed Daki to inspect the flowers, and Lin called for an attack.

• Tengen Uzui explained that the Master had asked the Hashira to watch for news about plants, and an oiran’s request for blue flowers had drawn his attention.
• Tengen Uzui invited Giyu Tomioka to investigate with him and Lin Yoriichi, then teased Giyu about smiling; Giyu tried and made an awkward expression.
• The three Hashira reached the Entertainment District at evening, and Lin Yoriichi recognized the Kyogoku House as the place where the oiran had requested blue flowers.
• Daki presented her collected flowers to Muzan Kibutsuji, who took control of her body and searched through them for a Blue Spider Lily.
• Muzan Kibutsuji found no Blue Spider Lily and continued using Daki’s body to experience the outside world, assuming the Kyogoku House was safe.
• Lin Yoriichi stared at the Kyogoku House and told Tengen Uzui and Giyu Tomioka to prepare to strike.

Lin Yoriichi, Giyu Tomioka, and Tengen Uzui launched a surprise attack on Kyogoku House, where Muzan Kibutsuji was controlling Daki’s body. Daki attacked the swordsman in the middle, then recognized Lin Yoriichi as her sashes were cut apart.

• Lin Yoriichi, Giyu Tomioka, and Tengen Uzui reached the roof near Kyogoku House and coordinated a careful attack to protect the civilians.

• Gyutaro picked up Daki’s head and ran from the Kyogoku House.

Gyutaro unleashed a wide-ranging Blood Demon Art to cover his escape with Daki, but Lin Yoriichi deflected the attack and beheaded him. Afterward, Lin discovered the bloodlike medicine spilled on his uniform gave off a peculiar fragrance that affected Gyutaro, and Giyu remarked that Lin smelled nice.

• Gyutaro fled with Daki's incomplete head and unleashed a barrage of blood scythes to delay the Demon Slayers.
• Tengen Uzui and Giyu Tomioka charged to stop the attack, but Lin Yoriichi deflected the scythes and beheaded Gyutaro.
