Awful Villain

Nezuko burns the blood blades with her fire. Tanjiro reunites with Zenitsu, Inosuke, and Tengen, while Nezuko burns Gyutaro's poison from their bodies. She and Tanjiro set out to finish off the demons and find them insulting their relationship. When Daki fades away right in front of him, Gyutaro calls her by her true human name; Ume. As he fades into nothing, Gyutaro recalls their past. They were born in a red-light district into poverty and suffered from an abusive mother; despite his appearance burdening him, Ume, considered very attractive as a child, gave them a comfortable life. One day, she attacked a customer of hers and was burned in retaliation. Gyutaro found her and killed the people responsible. They were found by the Upper Rank Six of then and transformed. In the afterlife, the siblings reconcile and walk to Hell together. Serpent Hashira Obanai Iguro arrives, sarcastically praising Tengen for killing Upper Six. However, Tengen relinquishes his position and informs him of Tanjiro's potential. An increasingly ill Kagaya is overjoyed at the news, while Akaza is summoned to the interdimensional Infinity Castle, where he realizes that an Upper Rank has fallen.
