Chapter Summaries

Kurozawa prepared to finish off Doma, but Hongyue arrived in Lotus Town before he could attack. Doma urged her to kill Kurozawa, while Kurozawa braced himself for a fight despite his uneasy feelings about breaking his promise to her.

• Kurozawa advanced on the weakened Doma, who offered a truce and warned that Kurozawa could not kill him before dawn.
• Kurozawa sensed an extraordinarily powerful scarlet Fighting Spirit approaching and recognized its owner as Hongyue.

• Kurozawa greeted Hongyue, then became wary when Doma accused him of destroying the Eternal Paradise Cult and killing Gyutaro and Daki.
• Doma warned Hongyue about Kurozawa's sword, Pitch-Black Flames, and explosive attacks as he knelt before her.

Hongyue met Kurozawa in Lotus Town and admitted she was the demon king, explaining that she had come because she feared he was in danger. When Kurozawa confronted her about killing demons, she offered him the Moon ranks and proved her control by binding Doma and placing him at Kurozawa’s feet.

• Hongyue silenced Doma, while Kanae watched and suspected Hongyue was the red demon who had destroyed Mount Fujikasane and killed the Flame Pillar.
• Hongyue told Kurozawa she had rushed to Lotus Town after Iguro Obanai said he was there, and Kurozawa challenged her for never revealing she was a demon king.
• Hongyue said she had not hidden her identity because Kurozawa had never asked, and Kurozawa told her he had killed Gyutaro, Daki, a Lower Moon, and many other demons.
• Hongyue smiled and offered Kurozawa the other Moon ranks, then used her blood to bind Doma and throw him at Kurozawa’s feet.

Hongyue handed Doma over to Kurozawa, who chose to spare him and sent him to hide in Asakusa with Kanae. Left alone with Hongyue in Lotus Town, Kurozawa asked why she trusted him, and she drew him into an unknown space with her Scarlet Armor.

• Doma tried to break free, but Kurozawa subdued him with Pitch-Black Flames before deciding to spare him for his value against the Demon Slayer Corps.

• Doma left Lotus Town with the nearly immobile Kanae as the ice crystals vanished, leaving Kurozawa and Hongyue alone.
• Kurozawa asked Hongyue why she treated him with such trust, and she pressed their brows together as her Scarlet Armor enclosed them and drew his consciousness into a blank space.

Kurozawa met Kamado Kawarutoki, a former transmigrator and Hongyue’s father, who showed him memories of his life and the catastrophe that destroyed his world. Kawarutoki revealed that he had died, reincarnated across worlds, and discovered that so-called world wills were Divine Wills left by gods.

• Kurozawa met Kawarutoki, who identified himself as a transmigrator and said Hongyue was more or less his daughter.
• Kawarutoki showed Kurozawa memories of becoming a demon, defeating Muzan Kibutsuji, recovering from Muzan’s blood, and marrying Kocho Shinobu.

• Kawarutoki told Kurozawa that he had been reborn in other worlds through endless reincarnation to gather strength.
• Kawarutoki explained that gods existed above worlds and that the beings people called world wills were actually Divine Wills.

Before vanishing, he revealed how he had prepared Hongyue to help Kurozawa and asked him to kill the deity if he ever could.

• Kawarutoki told Kurozawa that the Demon Slayer World had repeated the same events through countless cycles and that its Divine Consciousness tried to eliminate anyone who disrupted them.
• Kawarutoki explained that reaching a world's pinnacle allowed them to travel onward, retain the authority they had stolen, and cultivate it again in another world.
• Kawarutoki revealed that he was truly dead and that the voice speaking to Kurozawa was a consciousness he had left inside Hongyue's mind.
• Kawarutoki said he had adopted Hongyue, taught her about the world's cycle, and prepared her to help Kurozawa, whom he believed could surpass his own limit of fifty-six worlds.
• As his consciousness disappeared, Kawarutoki asked Kurozawa to kill the deity controlling the Demon Slayer World if he ever became strong enough.

• Kurozawa’s demon instincts stirred as hunger grew, and he rejected eating people despite knowing ordinary food would not satisfy his demon body.
• Kurozawa reached the mountain path near the Kamado home and decided to use coercion and temptation to obtain the Dance of the Fire God.

• Kurozawa sensed Kie and the children inside the house but could not detect Tanjuro, so he decided to abduct the siblings and demand a Breathing Technique as ransom.

• Kurozawa saw no fighting spirit in Tanjuro and wondered how he had concealed himself, while Tanjuro warily demanded to know who he was.

• Tanjuro wavered under the threat and offer, though he remained bound by his family's rule against passing the technique to outsiders.

Kurozawa forced Tanjuro Kamado to demonstrate the Kamado family's Breathing Technique so he could learn its rhythm, but the technique caused him intense pain. Before he could finish memorizing it, Gyomei Himejima arrived and Tanjuro stopped; Kurozawa asked Gyomei how his captured master was doing.

• Tanjuro Kamado agreed to demonstrate the Breathing Technique in exchange for his family's safety and asked Kurozawa to teach it to Tanjiro.
• Kurozawa copied Tanjuro's breathing rhythm, but the resulting aura caused him searing pain, so he switched back to Water Breathing and asked Tanjuro to continue.

• Gyomei evaded and blocked Kurozawa’s attacks, while asking whether the Demon Slayer Corps had judged him wrongly.
• Kurozawa gauged Gyomei’s sensing range, stepped outside its strongest area, and attacked with Bright Day and Secret Technique Sword Form: Annihilation.

Kurozawa fought the Stone Pillar to a standstill, then used Tanjuro Kamado and his family as leverage to make Tanjuro demonstrate the final segment of Sun Breathing. The Stone Pillar could not intervene without risking their lives, and Tanjuro began the demonstration.

• Kurozawa’s blade-light assault wounded the Stone Pillar, who counterattacked with his iron chain and forced Kurozawa to retreat.

• Tanjuro resumed his breathing demonstration and showed the final segment of the Breathing Technique.
