• Haruto sensed numerous demons and found them slaughtering villagers and passing absorbed energy through their antennae to a huge demon.
• Haruto recognized the huge demon as Koyuki, formerly Lower Rank Four and now Lower Rank Six.

Tanjiro and Genya fought demons on Mount Sagiri, where Tanjiro awakened Hinokami Kagura and beheaded his opponent. Elsewhere, Haruto killed Koyuki and concealed that her demons had been humans, leaving him burdened by guilt.

Haruto dreamed he was a Kasugai Crow alongside his ancestor Takanashi Sōma and watched Sōma demonstrate his extraordinary ability to read and pursue lightning. The dream ended with Sōma receiving an order to go on a mission in the Shinagawa Entertainment District, leaving Haruto stricken with dread.

• Haruto dreamed he was a Kasugai Crow perched on Takanashi Sōma, who was waiting for lightning beside a cliff.
• Sōma told Ryoji he had refused to become the Rumble Hashira because his pregnant wife, Hanae, needed his time, though he would continue taking missions.
• Sōma urged Ryoji to pursue the Hashira rank and explained that reading the temper of steel was a prerequisite for entering the true world.
• Sōma chased lightning with his blade as Haruto watched, then carried Ryoji and Haruto toward shelter when the storm broke.

Haruto practiced focusing his vision until he briefly slowed the falling rain, then used the ability to hunt snowcocks with Tanjiro and Genya. When the boys asked to take the Mount Fujikasane trial, Haruto consulted Sakonji Urokodaki, who set them a boulder-cutting test.

• Haruto briefly saw the rain move in slow motion before a gust blew water into his face and ended the effect.
• After the first snowfall, Haruto used his sharpened vision and slingshot to kill three snowcocks at once while Tanjiro and Genya hunted with him.

• Haruto returned from patrol and found Sabito sitting on a giant boulder; Urokodaki then told Tanjiro and Genya they had to meet the boulder-cutting requirement.

Haruto and Sabito joined Kyojuro and Mitsuri in Tokyo to hunt a demon suspected of abducting children during the Shichi-Go-San Festival. As the search began, five-year-old Kaoru became separated from his parents and was swallowed by a jade pot.

• Kaoru touched the pot and was swallowed as a shrill voice laughed from inside it.

Haruto and the other Hashira discovered that a demon was using enchanted pots to abduct children and identified him as Upper Rank Five, Gyokko. Mitsuri Kanroji encountered Gyokko alone, and he attacked her with his Water Prison Pot Blood Demon Art.

• Haruto questioned the parents of missing Shuko and noticed a strange pot on a stall roof.

• Mitsuri shattered one of Gyokko's pots, and Gyokko retaliated by using Water Prison Pot.

Mitsuri Kanroji escaped Gyokko’s Water Prison Pot when Kyojuro rescued her, while Haruto and the others confronted the demon. Gyokko unleashed goldfish toward festivalgoers and revealed a grotesque sculpture, prompting Haruto to provoke him into attacking with his Blood Demon Art.

• Mitsuri Kanroji struggled to escape Gyokko’s Water Prison Pot and remembered how the Demon Slayer Corps had accepted her.

• Haruto mocked Gyokko’s inability to defend his art, enraging him until he unleashed Blood Demon Art: Octopus Pot Hell.

Haruto, Kyojuro, and Mitsuri fought Gyokko as he unleashed giant octopus tentacles, and Haruto severed the demon’s head before realizing he had only struck a shed skin. Gyokko emerged in a faster, scale-covered true form, but Haruto dismissed his transformation as unimpressive.

• Gyokko attacked Haruto, Kyojuro, and Mitsuri with enormous octopus tentacles, which they cut apart with their Breathing techniques.

• Gyokko attacked the slayers with Ten Thousand Gliding Sticky Fish, and Haruto and Kyojuro shielded Kanroji while Sabito returned from evacuating civilians.
• Haruto struck Gyokko's arm, but Gyokko transformed the tip of Haruto's blade into a fish with his God's Hand.
• Haruto taunted Gyokko about his former life as a potter, enraging him and prompting him to unleash Thousand Needle: Fish Kill.
• Gyokko's poisoned needles numbed Haruto, but the antidote and his resistance helped him recover while Sabito and Kyojuro held off the demon.
• Haruto concentrated on Gyokko's movements until he saw Gyokko's body turn transparent and entered the transparent world.

Haruto used the Transparent World to analyze Gyokko and helped Sabito, Kyojuro, and Mitsuri Kanroji defeat the Upper Rank demon. After Gyokko died, Haruto collapsed with his broken sword and feared the Wind Chime Spirit would hunt him again.

• Haruto entered the Transparent World, saw through Gyokko’s movements, and cut the demon while Sabito and Kyojuro fought him.

• Haruto used Star Breathing, Ninth Form: Moon-Banishment, and severed Gyokko’s head.
• Haruto smashed Gyokko’s pot and condemned his art as trash as the demon crumbled away.
• Kyojuro celebrated the victory, Mitsuri Kanroji cried with relief, and Sabito checked on Haruto, who lay exhausted and worried that the Wind Chime Spirit would hunt him again.

Gyokko’s childhood in a fishing village showed how his grotesque art and disregard for human life took shape. After he killed a child and was left for dead, Muzan offered him demonhood, and Gyokko accepted, slaughtered the villagers, and became an Upper Rank demon devoted to Muzan.

• Gyokko drank Muzan’s blood, killed everyone in the fishing village, and became an Upper Rank demon devoted to Muzan.

After the Demon Slayer Corps learned that Haruto, Urokodaki, Rengoku, and other swordsmen had slain Upper Rank Five, Gyokko, Kagaya and Shinobu worried about the cost of the battle. Haruto arrived at the Butterfly Mansion, where Shinobu embraced him, and he reassured her that everyone would be all right.

• Haruto urged Kagaya to visit Tamayo if he wanted to live to see Muzan killed, while admitting he did not know what he might become.

Haruto faced competing invitations from the Hashira, who wanted to learn more about the Transparent World, while Muzan assembled the Upper Ranks in the Infinity Castle after Gyokko's death. Muzan condemned their failures and ordered them to avoid drawing attention as he pursued the Blue Spider Lily and a demon immune to sunlight.

• Gyomei Himejima, Tengen Uzui, Kanae, Shinobu Kocho, and Sanemi Shinazugawa tried to persuade Haruto to visit them and explain the Transparent World.
• Akaza confronted Doma in the Infinity Castle, and Doma teased him about eating women and challenging him in a rank replacement blood battle.

Haruto watched Tanjiro and Genya struggle to cut the oversized boulders on Mount Sagiri while Takeo joined them and shared the Kamado children’s grief over their family. When Shinobu arrived to examine Nezuko, she brought Kanao, who appeared to be training as a Demon Slayer candidate.

• Haruto learned from Urokodaki that Sanemi had secretly asked him to make Genya’s entrance-test challenge harder, so Urokodaki had enlarged both Genya’s and Tanjiro’s boulders.
• Takeo told Haruto that the Kamado children missed their mother and siblings, and that he was afraid to bring them to see the sleeping Nezuko.
• Haruto let Tanjiro and Genya continue their futile boulder training, believing they needed to experience helplessness and push past their limits.

• Shinobu praised Kanao’s keen eyesight, told Tanjiro to practice Sun Breathing more, and reassured Genya that he was already doing well.

Genya struggled with the limits of his abilities, but Haruto and Tanjiro supported him as he chose to keep training. With the next trial on Mount Fujikasane less than a month away, Genya finally split a boulder with one slash after taking a Demonization Pill, while Tanjiro advanced in Sun Breathing.

• After Shinobu Kocho and Kanao left, Tanjiro discovered that his keen sense of smell revealed threads leading to his opponents' weaknesses, and he split a boulder.
• Tanjiro encouraged Genya to use one of his keen senses, but Genya believed his sense of taste meant he could only grow stronger by devouring demons.
