Ubuyashiki, the leader of the Demon Slayer Corps, finally appears before Tanjiro. He tells him that he will allow Tanjiro and Nezuko to join the Corps. But the Hashira are unable to accept this decision right away. The Wind Hashira, Sanemi Shinazugawa, slashes his own arm and taunts Nezuko with his blood, trying to get her to show her true colors as a demon.
Tanjiro is pinned by Obanai but uses a breathing technique to break the ropes on his wrists and run to Nezuko, Giyu grabbing Obanai so he doesn't interfere. He stops by the porch and calls out to her, knowing he can't interfere directly. Nezuko remembers her family and controls her instincts, looking away from Sanemi. The Master takes that as proof she can be trusted and Sanemi stops, shocked.
The Master tells Tanjiro and Nezuko to go out and defeat demons and prove themselves and Tanjiro declares the siblings will defeat Kibutsuji, though the Master gently points out that he's so ill-equipped he'd better start with a Twelve Moon, embarrassing him - though the Hashira warm up to him some, admiring his spirit. Two Kakushi take Nezuko (again in her box) and Tanjiro to the Kocho mansion.
Tanjiro tries to come back to headbutt Sanemi for stabbing Nezuko again but Muichiro knocks him down with two well-placed pebbles to the head informing him that there is a protocol: Do not interrupt the Master. Tanjiro is taken away again. As he leaves, the Master tells Tanjiro to give Miss Tamayo his regards, making Tanjiro realize that he knows that there are good demons. At the Butterfly Manor, the Kakushi look for someone to ask permission to enter and find Tsuyuri, a Tsuguko (a swordsman trained by a Hashira). When they ask permission, she smiles but doesn't speak, confusing them.
A Kocho girl interrupts them and escorts them to the infirmary; in it, Zenitsu is whining about the bitter medicine which he must take to regrow his limbs, still deformed from the venom. Zenitsu and Tanjiro happily greet each other, and Zenitsu points out Inosuke, silently laying in a bed next to him. Tajiro is relieved that he survived and Inosuke hoarsely says not to worry, his voice damaged from the wounds which he was given by the Father demon. He's depressed and apologizes for being so weak. Nezuko is given a room of her own and she only makes it part way out of her box before falling asleep. Tanjiro affirms his promise to turn her into a human.
The Hashira, meanwhile, resume their meeting. The demons are in an active phase right now and the Corps needs to recruit new members, and train them well, as Sanemi points out that the events at Mt. Natagumo made it clear that the caliber of non-Hashira has plummeted. Shinobu KochoIt voices that it is difficult to recruit in this era though as many don't believe that demons exist and the more humans there are, the less unified they become. Gyomei Himejima states that only those who have lost loved ones to demons or descended from demon slayers are joining the Corps and asking laypeople who lack the will to fight would be too cruel.
The Master believes that Rui's drastic actions confirm that Kibutsuji is nowhere nearby as whenever the progenitor wants to hide something, he creates a diversion somewhere else that can't be ignored. After everyone leaves, the Master vows that they will bring Kibutsuji down without fail.
