Tanjiro comes face-to-face with the nine most powerful Demon Slayers: Giyü (the Water Pillar), Shinobu (the Insect Pillar), Kyöjuro Rengoku (the Flame Pillar), Tengen Uzui (the Sound Pillar), Mitsuri Kanroji (the Love Pillar), Muichirö Tokitö (the Mist Pillar), Gyömei Himejima (the Stone Pillar), Obanai Iguro (the Snake Pillar), and Sanemi Shinazugawa (the Wind Pillar). They put Tanjiro on trial due to him having violated Demon Slayer Corps rules by traveling 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...
