Ruined Survival AU: KNY

After the final battle, DKT had accidentally bitten a villager in their late teens, as a result of this incident, he could not turn back into a human due to already having the taste of human blood in his system. Although, since that, Tanjiro had not eaten or tried to eat another human being. With not laying his teeth on another human for 1 year, master Kiriya had entrusted Tanjiro and had (human) Nezuko give him a bamboo muzzle, similar to the one she had when she was a demon. Since Tanjiro can still turn people into humans - not that he plans to - the demon slayer corps can not end. Giyuu Tomioka ( former water pillar ), and Sanemi Shinazugawa ( former wind pillar ), have retired due to serious injuries from the final battle, but they still hang around the Ubuyashiki mansion with Nezuko, Tanjiro and others often. The current hashiras / pillars are: Nezuko Kamado (blood hashira ), Zenitsu Agatsuma ( rumble hashira ), Inosuke Hashibira ( beast hashira ), Kanao Tsuyuri ( flower hashira ), Genya Shinazugawa ( demon hashira ), and Murata ( water hashira ).
