After the battle is over, Tanjiro and Nezuko are taken to the Demon Slayer Corps headquarters. This is where the Hashira Meeting between the Corps leader, Ubuyashiki, and the Hashira, the most powerful swordsmen in the Corps, is to be held. The Hashira censure Tanjiro for violating the Demon Slayer Corps by protecting a demon. And then, the Wind Hashira, Sanemi Shinazugawa, raises his sword against Nezuko...
Tanjiro comes face-to-face with the nine most powerful Demon Slayers: Giyu (the Water Hashira), Shinobu (the Insect Hashira), Kyojuro Rengoku (the Flame Hashira), Tengen Uzui (the Sound Hashira), Mitsuri Kanroji (the Love Hashira), Muichiro Tokito (the Mist Hashira), Gyomei Himejima (the Stone Hashira), Obanai Iguro (the Serpent Hashira), and Sanemi Shinazugawa (the Wind Hashira).
They intend to put Tanjiro on trial due to his violation of the Demon Slayer Corps rules by travelling with a demon, even if she is his sister. Tanjiro states she won't eat humans and can fight with the Demon Slayers to protect humans. Sanemi comes outside with Nezuko Kamado in her box, calling him deluded and stabs through the box and into Nezuko's shoulder. Tanjiro charges him and Giyu calls out that the Master will soon be here and to stop, which startles Sanemi, giving Tanjiro and opening to headbutt him and knock him to the ground, putting himself between the box and Sanemi, which impresses the Hashira. Obanai deduces that Giyu shouting out was likely a distraction, but is still impressed that Tanjiro was still able to get a blow in.
The Master of the Demon Slayers arrives before Sanemi can strike him back and all the Hashira kneel, with Shinazugawa simply forcing Tanjiro's head down. The Master is a blind man with scars across the upper half of his face, but Tanjiro is uncertain if it is an injury or sickness, accompanied by two white-haired girls. The Master states he has sanctioned the situation with Tanjiro and Nezuko and asks the Hashira to accept it, but most don't. The Master has one of the girls with him summarize a letter from Sakonji Urokodaki, the former Water Hashira, asking the Master to approve of Tanjiro's situation as Nezuko has not lost her human emotions or harmed a human. If Nezuko does assault a human, he vows himself, Tanjiro, and Giyu will all commit seppuku (ritual suicide), and their loyalty shocks Tanjiro.
Sanemi says that regardless of how they choose to kill themselves, whether it be burning; hanging; or seppuku, it won't guarantee their safety, and Kyojuro agrees that they can't bring back the human whom Nezuko will kill and rejects it with Sanemi. The Master agrees that there is no guarantee that she won't attack humans, but they can't prove that she will attack humans either. Even when starved, she has not harmed even one human in two years and there are three people who would vouch for her with their lives, so the Master will risk it unless the Hashira can give a more convincing argument that she may attack humans. He then adds that Tanjiro has met Kibutsuji, shocking them as previously no Hashira has ever seen the reclusive progenitor of demons, at least none that have survived. They start demanding that he tell them details about Kibutsuji until the Master breaks them up. Kibutusuji has sent pursuers after Tanjiro, perhaps only to silence him and Nezuko, but it's the first time he's revealed himself and the Master doesn't want to let him fade away again.
Sanemi continues to refuse the Master stating that if it were human then it would be a different matter, but he is unwilling to let Nezuko live as she's a demon in light of how much the Demon Slayer Corps has been through and how many of their own whom they've lost to other demons thus far. He cuts open his arm to prove that she can't be trusted. After tossing the box inside a house out of the sun, he stabs Nezuko twice more through the box and opens it, telling Nezuko to attack him for the human blood which she hungers for. Tanjiro attempts to stop this madness so Obanai elbow drops him to stop him, also cutting off his oxygen supply. Nezuko stands from the box, badly wounded, and turns to him, salivating through her muzzle and preparing to attack.
