Kimetsu no Yaiba: Yuukaku-hen

Tanjiro visits Kyojuro's family before joining Tengen Uzui in Yoshiwara

Akaza encounters Muzan, disguised as a young boy, who expresses disappointment that Akaza failed to eliminate three Demon Slayers besides Kyojuro. Akaza vows to kill Tanjiro, who is visiting Kyojuro’s brother Senjuro and their alcoholic father, a former Flame Hashira. The father initially dismisses Tanjiro violently but recognizes his earrings as evidence of Sun Breathing lineage. Tanjiro headbutts him for disrespecting Kyojuro, knocking him unconscious. Senjuro later thanks Tanjiro for delivering his brother’s messages. Four months after Kyojuro's death, Tanjiro, Zenitsu, and Inosuke accompany Sound Hashira Tengen Uzui on a mission to infiltrate the Yoshiwara red-light district, where demons are rumored to reside.

Tengen Disguises Slayers to Investigate Missing Wives in Yoshiwara

Concerned by the silence from his three wives sent to investigate demonic activity in Yoshiwara, Tengen disguises Tanjiro, Inosuke, and Zenitsu as women and sells them to the respective courtesan houses where his spouses were deployed. The three demon slayers successfully gain employment within the establishments. While Tengen observes the district from the rooftops, the narrative reveals that Makio, one of Tengen's wives, is being held captive in a secluded room within Inosuke's assigned house. She is restrained by numerous obi and is currently enduring interrogation from a mysterious female voice, highlighting the immediate danger facing the infiltrators.

Inosuke chases a mysterious presence while Zenitsu faces the wrath of Upper Rank Six Daki.

Inosuke searches a room he assumes belongs to Makio, expecting a demon, but finds it empty and messy. He detects movement within the structure and pursues the unseen entity without success. Meanwhile, Zenitsu protects a girl from Warabihime, the intimidating Oiran of the house. Although he identifies her as a demon, she attacks him in rage. Prior to the mission, the madam discovers Warabihime’s true nature and is killed by being dropped from a height. Warabihime then meets Muzan, who praises her strength and beauty, revealing her identity as Upper Rank Six Daki. Zenitsu wakes up after being cared for by the girls he defended, who thank him for his bravery. Shortly after they depart, Daki secretly captures Zenitsu.

Tanjiro and Inosuke reunite while Tengen investigates a demon threat in the pleasure district.

Tanjiro and Inosuke meet to share information, but their discussion is interrupted by Tengen, who learns Zenitsu is missing. Tengen orders the pair to leave to avoid unnecessary danger, yet they refuse and prepare for combat. Tanjiro visits the Oiran of his assigned house, who knew he was male, and says goodbye. Meanwhile, Tengen interrogates the house master at knifepoint for details about the demon. Tanjiro returns after detecting a scent, only to encounter Daki, who has absorbed the Oiran into her obi. Daki swiftly defeats Tanjiro using her sashes, breaking the strap on Nezuko’s box. Forced to leave his sister behind, Tanjiro acknowledges her as the most powerful demon he has faced and prepares to fight her alone.

Tanjiro struggles with exhaustion while Inosuke discovers a cavern holding Daki's obi and trapped victims.

Tanjiro fights Daki alone but finds his body too fatigued to effectively use the Hinokami Kagura. Meanwhile, Inosuke finds a narrow passage beneath his residence that leads to a cavern used as a holding cell by Daki. The space contains obi that Daki used to absorb victims, which function as independent entities. Inosuke initially tries to destroy the obi but chooses to rescue the people trapped inside instead. Although overwhelmed, he frees Suma, Makio, and Zenitsu. These survivors join the battle, and they are eventually joined by Tengen. Together, they confront the threat posed by the obi and Daki in this intense confrontation.

Tanjiro and Nezuko clash with Daki amid district destruction and shifting memories.

During the battle, Daki causes massive destruction, killing many innocents. Tanjiro retaliates with powerful Hinokami Kagura attacks, nearly severing her neck, but she transforms it into an obi to survive. As they fight, Daki recalls distant memories she attributes to Muzan's cells. Tanjiro nearly cuts her again but collapses from suffocating without breathing, saved by a vision of his late sister. Daki approaches the injured Tanjiro, but Nezuko appears and kicks off Daki's head. Remembering Muzan's orders to exterminate Nezuko, Daki engages her. Although Daki seemingly bisects Nezuko, she is stunned by her rapid regeneration. Nezuko removes her bamboo muzzle, matures in appearance, and faces Daki with intense rage.

Nezuko battles Daki while Tanjiro restrains her bloodlust as Tengen confronts the demon siblings.

Nezuko engages Daki in combat, sustaining severe injuries that she regenerates instantly, shocking the demon into admitting her healing power surpasses her own. Nezuko overpowers Daki, hurling her into a building where she nearly attacks a bleeding civilian before Tanjiro intervenes to restrain her. Tengen arrives and decapitates Daki, though she survives by summoning her brother Gyutaro from within her body. As Upper Six demons, they fight together; Gyutaro, jealous of Tengen’s appearance, attacks with sickles and Blood Demon Art. Tengen struggles to protect the civilians against their combined assault. Just as Tanjiro calms Nezuko, Zenitsu and Inosuke arrive to assist in the battle against the resilient demon siblings.

Tengen battles the siblings while Tanjiro defends against Gyutaro using Water Breathing.

Tanjiro tends to his injuries while preparing for the upcoming conflict. Tengen engages in a verbal clash with Gyutaro and Daki, reflecting on his past as a Shinobi trained by his father. He sought guidance from Kagaya alongside his wives to avoid his brother's fate. During the fight, Tengen separates the siblings but realizes he has been poisoned by Gyutaro. Tanjiro, Zenitsu, and Inosuke arrive to support him, earning Tengen's praise. Suma and Makio evacuate the district, and a recovering Hinatsuru joins the battle. The Upper Rank siblings coordinate their attacks, overwhelming the Demon Slayers. Tengen faces Gyutaro while Daki fights Zenitsu and Inosuke. Tanjiro switches to Water Breathing for better defense against Gyutaro. Hinatsuru attacks Gyutaro with wisteria-laced kunai, allowing Tengen to sever his legs and Tanjiro to strike.

Tengen and Tanjiro confront Gyutaro while Zenitsu and Inosuke battle Daki’s obi.

Tengen recalls his promise to his wives to live flamboyantly and retire after defeating an Upper Rank demon. He and Tanjiro attack Gyutaro, who neutralizes wisteria poison and regenerates his legs. Gyutaro uses a new Blood Demon Art to vanish and threaten Hinatsuru. Tanjiro combines Hinokami Kagura and Water Breathing to save her, earning Tengen’s gratitude. They resume their assault, but Gyutaro blocks the blades and forces Tengen to intervene, separating the fighters. Tanjiro joins Zenitsu and Inosuke against Daki. Inosuke decapitates her to prevent reattachment, but Gyutaro ambushes him, stabbing him through the chest and reclaiming the head. Tanjiro witnesses Tengen’s severed hand and unconscious body, freezing in despair. Zenitsu pushes Tanjiro off the roof to save him from an incoming obi attack.

Tanjiro and allies defeat Upper Six demons amidst city destruction and poison.

Surviving his fall, Tanjiro finds Nezuko safe in her box but is attacked by Gyutaro, who mocks his failures. Gyutaro offers Tanjiro demonhood, which he rejects by head-butting the demon. A wisteria kunai, lodged in Gyutaro’s leg from the impact, paralyzes him, allowing Tanjiro to strike with Hinokami Kagura. Daki intervenes but is swiftly attacked by Zenitsu, who slices her obi neck. Gyutaro removes the kunai and recovers, but Tengen, having slowed the poison, engages him evenly despite his missing arm. Tanjiro severs Gyutaro’s neck, activating his mark unknowingly while taking a jaw wound. Zenitsu, faltering from exhaustion, is joined by Inosuke, who survived a heart stab by moving his organs. The slayers simultaneously behead the siblings. As Tanjiro tries to counter the poison, Tengen urges him to flee before Gyutaro’s body explodes, destroying the area.

Tanjiro and Nezuko recover from the explosion and confront the dying demon siblings.

After the explosion, Nezuko survives safely using her Blood Demon Art. Tanjiro realizes he is no longer poisoned by Gyutaro and rejoins Nezuko. They find Zenitsu, who leads them to a dying Inosuke. Nezuko heals Inosuke by igniting the poison in his body. They also save Tengen, who is near death with his wives. Unable to move, Tanjiro asks Nezuko to carry him to find the demon siblings' heads. They discover the siblings arguing over their defeat. Tanjiro comforts them, prompting Gyutaro to recall his past. Born in a poor slum, Gyutaro suffered due to his ugliness until his sister Ume, later known as Daki, was born. Her beauty improved their lives, but she attacked a samurai at age 13 and was left to die. Gyutaro survived his own attack, killed his assailants, and was found by Douma. Douma offered them demonhood. Daki dies in agony, and Gyutaro joins her in Hell, where they reconcile. Obanai Iguro congratulates Tengen, who suggests Tanjiro replace him. Kagaya celebrates the victory at headquarters. Akaza learns of the defeat in the Infinity Castle. Tanjiro reunites with Zenitsu and Inosuke among the ruins.
