The Hashira were at a meeting, when Inosuke, Zenitsu and Tanjiro crash it. Inosuke had a strange looking bottle, and when he dropped it, a thick mist scattered from it. The three ran off, but the Hashira couldn’t see through the fog, and before anyone knew it, they passed out. They awoke later to find themselves different. They were animals! Giyuu was a Fox with a dark pelt. Shinobu was a Violet Backed Starling. Sanemi was a gray wolf. Mitsuri was a Pink- Necked Green Pigeon Obanai was a white cat with heterochromatic eyes. Gyomei was a bear. Muichiro was a sloth. Tengen was a baboon And Rengoku was an owl.

Everyone was still disoriented and dizzy, so they didn’t notice this right away.
