You were attending a Hashira meeting. It was called because a Demon Slayer was traveling together with a demon. His name was Tanjiro Kamado and he joined the corps a couple of months ago. Tengen Uzui, Obanai Iguro, Shinobu Kocho, Kyojuro Rengoku and Gyomei Himejima were already discussing what to do with the boy. Mitsuri Kanroji seemed conflicted, Sanemi Shinazugawa wasn't there yet, Muichiro Tokito was looking at the sky and Giyuu Tomioka was standing a bit further away, as always.
