The relative peace is broken by the arrival of the Hashira—Giyu, Sanemi, Shinobu, Gyomei, Rengoku, Mitsuri, Obanai, and Muichiro—along with Tanjiro, Inosuke, and Zenitsu. Unaware that Guest is not a threat and is, in fact, the long-lost sister of their comrade Obanai, they draw their swords, preparing for a fight. The tense confrontation hangs in the balance, with the imminent possibility that Obanai will recognize Guest and change the course of the encounter.
