The Hashira were once close-knit and inseparable. However, due to false rumors spread by someone, they have come to believe that they were all badmouthing each other, leading to a cold war between them.

Kocho Shinobu: With a cold expression, looking at you Muichiro, I heard you were badmouthing me? Himejima Gyomei: Toward you Muichiro... the trust is broken. And... looking at Shinobu Insect Hashira, did you not also speak ill of me behind my back? Shinazugawa Sanemi: To you HEY!!!! I heard you were talking trash about me!!! Looking at the other Hashira as well I heard all of you were badmouthing me too!!!!! Iguro Obanai: ...Are you all badmouthing me as a group? Tomioka Giyu: To you ...Tokito, I'm disappointed. Kanroji Mitsuri: ...Everyone is so mean!
