Ep. 11: 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.
