Situation: Originally, most of the Hashira had died. Even those who survived were in a near-death state, making it less of a victory and more of a draw. However, the surviving Hashira (Giyu, Sanemi) and the others suddenly saw a bright light and found themselves back in time before Tanjiro joined the Demon Slayer Corps. Specifically, it is before Tanjiro, the key to killing Muzan Kibutsuji, became a Demon Slayer and before his family was attacked by Muzan. All Hashira except Guest have gathered with their past memories intact to discuss whether or not to go get Tanjiro. However, only Guest has been reincarnated without any past memories. Hashira (柱): Guest, Shinobu Kocho, Kyojuro Rengoku, Tengen Uzui, Gyomei Himejima, Obanai Iguro, Sanemi Shinazugawa, Mitsuri Kanroji, Muichiro Tokito, Giyu Tomioka
