• Akaza activated Destructive Death: Compass Needle and lunged at Rengoku, while Yaha watched eagerly from the train roof.

Yaha watched Akaza overwhelm Rengoku, then awakened Sukuna’s instincts when Rengoku and Akaza prepared their strongest attacks. He intervened at the last moment, stopping Akaza’s Annihilation Style with one hand and confronting him.

• Akaza attacked Rengoku with Air Type, but Rengoku severed his arm with Blazing Universe before Akaza regenerated it.

• Tanjiro and Inosuke watched in shock as Rengoku recovered and Akaza rose again.
• Akaza activated Destructive Death, Compass Needle, but it failed to sense Yaha’s fighting spirit.
• Yaha threatened Akaza, then cut off half his left ear with an attack the Compass Needle could not detect.

Yaha faced Akaza, whose regeneration failed against the power that erased part of his ear. After dodging Akaza’s attacks and healing from a devastating kick, Yaha prepared a dark red flame to challenge the demon’s faith in his martial path.

• Akaza discovered that the missing half of his ear could not regenerate and realized Yaha’s power had erased the law behind his healing.

• Yaha struck Akaza with a knee that crushed his chest and sent him flying, while Akaza’s ear wound continued to smoke.
• A system message prompted Yaha to overwhelm Akaza and burn away his prized techniques, so Yaha dispersed his slashes and summoned a dark red flame.

• Akaza charged into the arrow, and their collision silenced the battlefield before white light swallowed them and the surrounding field.

Yaha defeated Akaza with Open (Flame Arrow), burning away his arms and leaving him unable to regenerate. As Akaza briefly glimpsed a woman from his human past, Yaha declared him not worth killing.

• Yaha's dark-red flames erased Akaza's Fighting Spirit and burned through his right arm, while Akaza's attempt to sever the limb only spread the fire to his left hand.

• Yaha taunted the ruined Akaza as Tanjiro, Rengoku, and Inosuke watched, while Yaha secretly endured damage from exceeding his body's limit.
• Akaza recalled a fleeting image of a woman from his past, and Yaha forced him to meet his gaze before saying he was not worth killing.

Yaha crippled Akaza and sent him back to Muzan Kibutsuji with a challenge, while Akaza escaped the rising sun by crawling into the forest. Yaha extracted a cursed object from Akaza’s severed flesh, and Kyojuro Rengoku knelt before him in reverence.

• Yaha extracted concentrated Muzan’s blood from Akaza’s severed flesh and obtained a finger-shaped cursed object.
• Kyojuro Rengoku arrived with Tanjiro, Inosuke, and Zenitsu, then offered Yaha his Nichirin Blade and bowed to him.

After defeating Akaza, Yaha forced Rengoku to stay alive and left before anyone could thank him. Alone in the forest, Yaha consumed the Origin Finger to repair his failing body, beginning to awaken the physical traits of the King of Curses.

• Rengoku knelt before Yaha and admitted defeat, but Yaha kicked him upright and ordered him to stay alive until he could kill an Upper Rank.
• Rengoku vowed to become strong enough that Yaha would not need to worry about him as Tanjiro realized Yaha had saved him in his own awkward way.
• Mutilated and burned, Akaza returned to Infinity Castle and told Muzan that Yaha had claimed his head, sending Muzan into a rage that shook the castle.
• Alone in the forest, Yaha discovered that his body was breaking down and that he had to consume the Origin Finger within 24 hours.
• Yaha ate the Origin Finger, and the resulting power began reconstructing his body and forming the first rudiments of his four arms.

After Yaha collapsed from the Crimson Cursed Object’s effects, Kyojuro Rengoku ordered the Hidden Corps to keep his demon-eating secret and had him rushed to medical care. At the Butterfly Mansion, Shinobu Kocho prepared to inject the restrained, unconscious Yaha in the carotid artery.

• Yaha swallowed the Crimson Cursed Object, briefly showing the phantoms of four arms before the glow faded.
• The Hidden Corps found Yaha beside Akaza’s remains, but Kyojuro Rengoku threatened them with a gag order and said Yaha had saved their lives.
• Yaha’s body failed during the reconstruction process, and Rengoku caught him as he collapsed and ordered him taken to Headquarters.
• Tanjiro and the Hidden Corps carried Yaha toward medical care while Rengoku worried that rumors of a demon-eating monster would reach the Hashira.
• At the Butterfly Mansion, Shinobu Kocho restrained the unconscious Yaha and aimed a specialized syringe at his carotid artery.

Shinobu Kocho tried to examine Yaha, but discovered that his body could not be pierced and that poison had no effect on him. After he woke and revealed his awareness of her fears, Sanemi Shinazugawa and Obanai Iguro arrived demanding to know where the demon-eating monster was.

• Shinobu Kocho attempted to draw Yaha's blood, but her specially made needle bent against his skin.
• Yaha woke, overpowered Shinobu, and resisted the poison she sprayed into his face.
• Yaha identified Shinobu's fear that her power would one day escape her control, then rejected eating her because her body tasted of wisteria poison.
• Yaha told Shinobu to bring him fifty kilos of roast meat, and she left the ward with the broken syringe.
• Sanemi Shinazugawa and Obanai Iguro arrived at the Butterfly Mansion, and Sanemi demanded to know where the monster that ate demons was.

Sanemi Shinazugawa and Obanai Iguro confronted Yaha at the Butterfly Mansion, but Giyu Tomioka defended him as his brother until Kagaya Ubuyashiki revealed that Yaha had defeated Akaza. Yaha emerged healed and learned that the Sound Hashira had gone missing in Yoshiwara, then set out to change before responding.

• Sanemi Shinazugawa and Obanai Iguro forced their way into the Butterfly Mansion, and Shinazugawa shoved Shinobu Kocho aside while demanding to find Yaha.
• Giyu Tomioka blocked the intensive care room and fought Shinazugawa and Iguro to protect Yaha, declaring, “He's my brother!”
• Kagaya Ubuyashiki stopped the clash and reported that Yaha had defeated Upper Rank Three Akaza alone.
• Yaha emerged from the room, intimidated Shinazugawa and Iguro into freezing, and pushed the injured Giyu behind him.
• Kagaya told Yaha that the Sound Hashira had gone missing in Yoshiwara three days earlier, where an Upper Rank was entrenched.
• Yaha headed out to change, remarking that the Sound Hashira was probably not dead yet.

Shinobu Kocho asked Yaha to help her kill Upper Rank Two, but he condemned her plan to sacrifice herself and told her to stay alive until he could kill the demon. Meanwhile, Muzan sensed Yaha’s body being reconstructed and ordered Nakime to prepare the Entertainment District as a means of burdening him.

• After the Hashira and the Ubuyashiki family left, Yaha returned to his ward and slept as his body continued reconstructing.
• Shinobu Kocho visited Yaha and asked him to use his cursed technique to help her defeat Upper Rank Two, offering to accept any terms.
• Yaha mocked Shinobu Kocho’s poison and her plan to die for revenge, leaving her sobbing beside his bed.
• Yaha told Shinobu Kocho to stay alive and watch him chop the demon into shaved ice, and she left saying she would remember his words.
• Muzan sensed Yaha’s accelerated reconstruction and ordered Nakime to prepare the Entertainment District by making its residents a burden for him.

Muzan learned from Akaza’s memories that Yaha’s devastating powers had limits, so he ordered Daki and Gyutaro to lure him into the crowded Entertainment District. At the Butterfly Mansion, Yaha corrected Tanjiro, Zenitsu, and Inosuke’s training, then sensed a deep hunger and leapt toward the mountain woods, where Tanjiro glimpsed a four-armed phantom behind him.

• Muzan reviewed Akaza’s memories, recognized Yaha’s primordial flame, and deduced that Yaha’s powers had a cost and an upper limit.
• Muzan ordered Nakime to warn Daki and Gyutaro to avoid open spaces and use the crowded Entertainment District as their battlefield against Yaha.
• Yaha woke at the Butterfly Mansion and demonstrated Inosuke’s weaknesses by kicking him into a tree and slamming him face-first into the dirt.
• Yaha corrected Tanjiro’s sword transition and Zenitsu’s stance, while Tanjiro’s strikes grew more precise and Inosuke kept demanding another fight.
• Yaha felt an intense hunger and sensed something in the mountain woods; Tanjiro saw a four-armed apparition behind him before Yaha vaulted over the wall and disappeared into the forest.

Yaha’s hunger and Sukuna’s instincts drove him to attack Shinobu Kocho, but his body healed her wound and stopped him before he could kill her. The next day, Kagaya Ubuyashiki ordered a task force to the Yoshiwara Pleasure District, where an Upper Rank demon was confirmed, giving Yaha a chance to find the essence he needed.

• Yaha crushed a lesser demon and absorbed its essence, but his body’s reconstruction barely advanced.
• Yaha’s instincts made him pin Shinobu Kocho against a tree and wound her neck, but Reverse Cursed Technique healed her and stopped his attack.
• Yaha left without looking back, while Shinobu Kocho realized he had kept himself from harming her and let go of her wariness.
• A Kasugai Crow delivered a report that contact with Tengen Uzui had been lost in the Yoshiwara Pleasure District and an Upper Rank demon was present.
• Kagaya Ubuyashiki ordered an Entertainment District task force to assemble, and Yaha faced the prospect of finding the essence his body needed there.

Yaha accepted Kagaya's mission to investigate the Entertainment District on the condition that he receive broad authority and unlimited food, while Shinobu was assigned to monitor his unstable mutations. Rejecting her plan to infiltrate the district in disguise, Yaha carried Shinobu at high speed toward Yoshiwara as they set out to find the missing Tengen and confront Upper Rank Six.

• Kagaya told Yaha that Tengen and the Kasugai Crows had gone silent and confirmed an Upper Rank Six demon in the Entertainment District.

• Yaha rejected Shinobu's disguise plan and said he would tear through the district, while Shinobu warned that charging into the underground labyrinth could endanger civilians and allies.
• Giyu stopped Yaha in the covered walkway and told him not to lose his guide, and Yaha flicked him on the forehead before leaving.
• Yaha crumpled Shinobu's route map, took her around the waist, and launched them into the sky toward the Entertainment District.

Yaha carried Shinobu Kocho to the Yoshiwara Entertainment District in just over two hours, shielding her from the wind with cursed energy. At the district entrance, he rejected Shinobu’s attempt to bribe the gatekeeper and insisted that he had come to kill demons, not go undercover.

• Yaha raced across the mountains and over a gorge with Shinobu Kocho in his arms, using cursed energy to protect her from the wind.

• A gatekeeper demanded that Yaha leave his Nichirin Blade behind, and Shinobu Kocho offered him money as a calling card.
• Yaha brushed aside Shinobu Kocho’s pouch of banknotes and said he had come to kill demons, not go undercover.

Yaha cleared Yoshiwara’s central avenue with his oppressive spiritual pressure, destroying Muzan’s hostage strategy. He then shattered Daki’s attacking sashes and cut apart a restaurant, calling her out from Kyogoku House.

• Yaha swept away the proprietor’s banknotes and unleashed spiritual pressure that extinguished the avenue’s lanterns, knocked out thugs, and turned demon informants to ash.
• Thousands of civilians fled Yoshiwara’s central avenue, and Muzan crushed a flask when he sensed his hostage shield had been cleared.
• Shinobu Kocho followed Yaha through the empty street toward Kyogoku House, while Daki trembled inside and prepared to test him with her sashes.
• Yaha traced an arc with his finger, shredding Daki’s three attacking sashes into fragments that carbonized into ash.
• Yaha sliced the nearby three-story restaurant into neat blocks, then called for Daki to come out.

Yaha dismantled Daki’s attack and left her unable to regenerate, drawing out her brother Gyutaro. The chapter ended with Yaha welcoming Gyutaro as a worthy opponent.

• Yaha pinned Daki beneath his boot and taunted her until Gyutaro burst from her back and threatened to kill him.
• Yaha dodged Gyutaro’s sickle and welcomed him as an opponent who could take a hit.

Yaha shrugged off Gyutaro’s poison and overwhelmed him with raw strength, then followed him underground to find Tengen Uzui and several civilians trapped in the granary. With Gyutaro unleashing an attack that would kill everyone in the chamber, Yaha awakened the cursed mark of a domain and prepared to fight back.

• Yaha revealed the cursed mark of a domain and declared that he would mince the entire space along with its occupants.
